  • Twins born on same day as their twin brothers, 4 years later

    Exactly four years after a British mother gave birth to a pair of twin boys, on July 18, she delivered a second set of naturally conceived twins, according to a report Thursday in the British newspaper The Sun. The mom, Kim Hefer, is reportedly the first woman in the United Kingdom to have to two sets of twins on the same day years apart. A bookie set the odds of this happening at 30 million to one, the paper reported.

    That’s only the most recent case of attention-grabbing coincidental births. A mother, daughter, and granddaughter all sharing the same birthday or twin sisters giving birth on the same day or a boy and girl born on the same day in the same hospital who grow up and decide to get married -- these odds-defying stories capture our imagination.

    What is it about shared birthdays that are so irresistible?

    Humans understand the world exists in certain ways; for example, we know that weather patterns, not angry gods, cause thunder. But something we perceive as coincidental, say a mother, daughter, and granddaughter sharing the same date of birth, seems so random to us so we believe that supernatural forces cause this coincidence.  

    “Basically any event is unlikely. If you flip a coin five times and it comes up heads each time, you think that something funny [has happened]. The probability of getting heads, heads, heads, heads, heads, is the same as any other sequence. It’s not that it is unlikely … there is something else about it that strikes us,” says Tom Griffiths, director of the Computational Cognitive Science Lab and the Institute of Cognitive Brain Sciences at the University of California, Berkeley.

    Griffiths and his colleague wrote a paper, which explores coincidences and also considers “the birthday problem.” A classic statistical exercise, the birthday problem aimed to discover how many people needed to gather in a room for two to share a birthday. If there are only 23 people in a room, there is a 50 percent chance that two share a birthday and this likelihood increases as the number of pairs entering the room grows. Griffiths’ findings reinforce what experts know about the birthday problem—shared birthdays aren’t as random as we like to think.

    “Why is it that people having the same birthday is something that strikes us? Is it that it suggests there is some underlying reasoning behind it? Our brains want to believe that it is something other than chance,” Griffiths says.

    Atlanta psychologist Robert Simmermon agrees that people assign meaning to random events, believing God, fate, karma, or the stars contribute to chance.      

    “One in 30 million chances … that chance is incomprehensible,” says Simmermon, who has a private practice. “We really can’t understand anything else that might be like it.”

    And people feel more intrigued by these birthday coincidences because birthdays carry a lot of emotional weight.

    “It’s the genesis; it is the beginning,” he says. “The birthday is the beginning of our existence … well, the beginning of our consciousness.”

  • Glass shape may influence how fast you down that beer

    Rita Juliana / Stock Xchng via MyHealthNewsDaily

    Beer drinkers take almost twice as long to finish when drinking from a straight-sided glass compared with a curved glass, according to a new study.

    MyHealthNewsDaily Staff

    How quickly you down an alcoholic drink may depend on the shape of the glass you're holding, a new study suggests.

    In the study, participants were asked to drink beer from either a straight-sided glass, or a curved "beer flute."

    People took about almost twice as long to finish when drinking alcohol from the straight-sided glass, compared with the curved glass. There was no difference in drinking rates from the glasses when the drink was nonalcoholic.

    People may swill their alcohol faster from curved glasses because it is more difficult to accurately judge the halfway point of these glasses, the researchers speculated. As a result, drinkers may be less able to gauge how much they have consumed.

    "People often talk of 'pacing themselves' when drinking alcohol as a means of controlling levels of drunkenness, and I think the important point to take from our research is that the ability to pace effectively may be compromised when drinking from certain types of glasses," said study researcher Angela Attwood of the University of Bristol's School of Experimental Psychology in the United Kingdom.

    In another experiment, participants completed a computer task in which they were shown pictures of two glasses containing varying volumes of liquid, and asked to judge whether each glass was more, or less, than half-full. The researchers found people made greater errors in judging the halfway point of the curved glass.

    The participants who showed the greatest error in these judgments also tended to show the greatest changes in their drinking rates, the researchers said.

    The speed at which people drink alcohol influences their level of intoxication, and the number of drinks they consume on an occasion. Therefore, slowing down is likely to have a positive impact for the individual, and also at a population level, the researchers said.

    Pass it on: The shape of a glass may influence how quickly we consume alcohol.

  • Myth, busted: The blue moon doesn't really make you crazy

    By Stephanie Pappas, LiveScience 
    With two full moons in August, the month would seem ripe for lunacy. But the idea that the moon contributes to madness is, fortunately, a myth.

    Friday, Aug. 31 will feature a blue moon, the second full moon of the month, an event that happens every 2.7 years, on average. (The next blue moon won't occur until 2015.) This double full moon might seem like good reason to stay indoors, given that the full moon has been linked to odd behavior in legends both old (werewolves, anyone?) and new (cops and emergency room staff have been known to blame the full moon for wild nights). In fact, scientists have looked into the connection between lunacy and the moon, and they've found very little evidence to back it up.

    Take, for example, emergency room visits. In 1996, researchers examined the history of more than 150,000 emergency room visits to a suburban hospital. They found no difference between full-moon nights and every other night of the month, they reported in the American Journal of Emergency Medicine. Other studies have tried and failed to find a link between the full moon and psychiatric emergency visits, epilepsy seizures and surgery outcomes. [ Gallery: The Fantastic Full Moon ]

    Most likely, the urban legends that spring up about illness, madness and the moon are examples of what psychologists call confirmation bias — the very human tendency to remember information selectively. If you're an emergency room nurse having a busy night and you happen to notice that the moon is full, you're more likely to remember the link than on a busy night when the moon is waxing or waning.

    So if humans aren't affected, how about animals? A 2007 study in the Journal of the American Veterinary Medical Association did find that more cats and dogs arrive at the veterinary emergency room at Colorado State University on full-moon nights. Cats had a 23 percent greater chance of requiring an emergency vet visit under a full moon than during other moon phases, while dogs had a 28 percent greater chance. The researchers couldn't say why the link existed, though it's possible that the full moon's brightness means more people are out and about with their pets on those evenings, increasing the risk of injury.

    Other animal studies have been similarly confounding. A study published in the British Medical Journal in December 2000 found that one emergency room in Great Britain saw more animal bites on or around full-moon nights, but a study in the same issue of the journal that focused on Australia found no such link. Perhaps the werewolves of London haven't made it to Sydney.

  • Woman's non-stop orgasms: Too much of a good thing

    The other day, a few media outlets in the New York region covered the story of a woman who can’t seem to stop having orgasms, which would seem joke-ready but can actually be a nightmare.

    While the New Jersey woman’s condition has not been formally diagnosed, it appears she has persistent genital arousal disorder (PGAD), something we explored years ago

    The syndrome usually manifests as a constant blood engorgement of the female genitals, mainly the clitoris. This creates a sensation of needing “relief.” Cue the jokes. But imagine constantly sensing the need for orgasm at work, on the bus, while visiting with friends, and then finding no relief, or only very temporary relief, if you masturbate. Genitals can become highly sensitive, and sore. Sufferers describe feelings of isolation and mental anguish.

    Unfortunately, nobody is quite sure what causes it or how to treat it, but, according to Jim Pfaus, a researcher at Montreal’s Concordia University who studies the neuroscience of sexual response, and who is currently engaged in studying persistent genital arousal, there are enough clues to develop a working theory.

    “The root cause,” he explained, “may be an irritation of the clitoral sensory nerves.” The brain interprets this sensation and sets off a cascade of events.

    A brain region called the pro-optic area responds to dopamine signaling by sending out instructions for the body to prepare for sex, as if a woman has been engaged in foreplay when, in fact, she’s not remotely in a sexual context. Blood flows to the genitals. “So we think that this blood flow is in a state of hyperarousal in women with PGAD,” Pfaus said. “They get engorgement quickly, reach orgasm quickly when they try to relieve themselves. It shares features with premature ejaculation and priapism” in men.

    That’s consistent with observations others have made. For example, Barry Komisaruk at Rutgers University found that of a group of 18 women with PGAD, 12 had cysts on nerves in the sacral region of their spines. The cysts may be stimulating clitoral nerves.

    A variety of drug therapies (there’s even one report of a physical therapy involving manipulation of muscles in the region) have shown to help. SSRIs, commonly used for depression, seem to provide some relief. But Pfaus believes the drug varenicline (Chantix, commonly used for smoking cessation) is most promising. It works by interrupting the signaling that leads to dopamine release. Blood stops flowing.

    While the therapy has worked in scores of women, Pfaus said, the drug isn’t perfect. “Unfortunately it comes back when they go off it.”

  • Can hurricanes make pregnant women go into labor?

    By Karen Rowan, MyHealthNewsDaily 

     

    Exactly what triggers the start of labor remains a mystery, but folklore holds that the weather may influence a baby's arrival. With Isaac -- now downgraded into a tropical storm -- making landfall, and two other storms brewing in the eastern Atlantic, some may be wondering if the Southeast is due for an increase in births.

    Several studies have suggested that drops in barometric pressure can trigger either the onset of labor, or the rupture of the fluid-filled amniotic sac membrane, which is the technical term for a woman's water breaking or starting to leak.

    "There's definitely a belief out there," said Dr. Jonathan Schaffir, associate professor of obstetrics and gynecology at Ohio State University College of Medicine. "It's certainly not cut-and-dried, but there is some scientific evidence that changes in pressure can contribute to membrane rupture," he said.

    Of the studies that have looked at whether the weather might trigger pregnant women's water to break, two have suggested that it can, while two others have found no association, Schaffir said.

    "The idea behind this belief is that the amniotic sac is like a balloon, and if you lower the external pressure on it, there is an increased risk it can 'pop,'" Schaffir said.

    However, in his own experience as a practicing obstetrician for 18 years, Schaffir said he has seen no link between weather events and women going into labor. "In reality, the amniotic sac is protected. It's kind of hard to imagine that a small drop in barometric pressure would cause a change in the  amniotic sac," he said.

    Dr. Salih Yasin, a practicing obstetrician for 25 years in Miami, also said he has not seen any increase in women going into labor during hurricanes.

    As for the studies that have suggested a link, their usefulness in practice is doubtful, said Yasin, who is an associate professor of obstetrics and gynecology at the University of Miami Miller School of Medicine. The ranges of the barometric pressure changes in the studies were not very large, he noted.

    In one study, researchers considered 162 women who, over the course of a year, went into labor at a Houston hospital around times of significant air pressure drops. Using air pressure data from the National Oceanic and Atmospheric Administration (NOAA), the researchers found that more women started labor after a drop in barometric pressure than prior to a drop, according to the study, published in 1997 in the Journal of Nurse-Midwifery. For example, for one drop in pressure, three women went into labor prior to it, but 11 began labor after it.

    When looking at the 12 pressure drops that occurred that year, they found 66 women began labor prior to pressure drops, whereas 96 women began labor after the drops.

    However, another study's results cast doubt on the link. In that 1996 study of about 2,400 pregnant women published in the American Journal of Obstetrics and Gynecology, the researchers found no link between days with the lowest pressure and the number of women who began labor.

    But when the pressure drops were broken down into three-hour time periods, there was a link: fewer women went into labor during the hour after a period of falling air pressure.

    "We were surprised to find a significant decrease in the onset of labor," after the pressure drops, the researchers wrote.

    Yasin and a colleague looked at deliveries around Aug. 24, 1992, when the lowest barometric pressures drops during Hurricane Andrew were noted, at the University of Miami Jackson Memorial Hospital, which had the most deliveries in Miami-Dade County before, during and after Hurricane Andrew hit, Yasin said.

    The researchers looked births and complications of pregnancy, and related them to NOAA data on barometric pressures, taking into account women's ZIP codes, to determine where they lived in relation to the Andrew's path. No association between air pressure and labor onset was found, Yasin said.

    The most important things pregnant women can do during extreme weather events are to maintain their safety, eat and stay hydrated, he said.

  • Swimming in her sleep? How the Idaho woman did it

    You may have heard about the 31-year-old Idaho woman who last week woke up after “sleep swimming” in the Snake River. She was found, suffering from hypothermia, along the shore. It was the second time she’d done it this summer.

    Sounds ridiculous, right? Sure, we’ve all heard of bizarre cases of “sleep driving” and “sleep eating” and even “sleep sex,” but sleep swimming? In a cold river? (I’ve been in the Snake River in Idaho, and I can tell you, it’s cold.) Surely, even if you could walk to the river in your sleep, that first splash of icy water would wake you.

    Not necessarily. 

    The problem with that popular notion, explained Dr. Mark Mahowald, visiting professor at Stanford University’s parasomnia clinic (parasomnia refers to sleep disorders involving behavior), is that “sleep” doesn’t have to be an all-or-nothing affair.

    Parts of your brain can be “asleep” while other parts are “awake.” Brain regions, mainly the frontal cortex, responsible for self-control, reasoning and laying down memories can be happily snoozing while parts of the deep brain, like the stem, can be “awake.”

    Because deep brain regions have been equipped with what Mahowald calls “central pattern generators,” patterns of physical acts, something like one of those dance steps instructors lay down on a floor, “you can have somebody who is sleepwalking, and be capable of performing extremely complex behaviors.”

    He likens it to a chicken that goes under the hatchet and then starts running around, headless, through the barnyard. The chicken doesn’t have any brain at all, and yet, because its spinal cord has complex pattern generators in it, the chicken runs.

    “In humans,” he explained, “there is good evidence that complex behaviors like running, screaming, shouting, sex acts, are all pre-packaged central pattern generators,” either learned or instinctive, that are let loose while the rational brain is sleeping.

    You’d have to know how to swim in order to swim in your sleep, of course -- you can’t just start playing Chopin in your sleep if you don’t already know how -- but this explains why people can drive, sometimes long distances, and not recall ever doing it.

    People have actually committed murder while sleeping, as documented on a website run by Mahowald and colleagues.

    The cold water of a river wouldn’t necessarily wake the sleeper because sleep is like being in a state of anesthesia. We tend not to feel pain or discomfort while sleeping, only after the event is over.

    “We had a case in Minnesota where a guy sleep walked outside, at 20 below zero, and sustained incredible frostbite on his feet,” Mahowald recalled. “He wasn’t aware until he woke up and saw the blisters.” 

    The causes of sleep walking vary, but may have a genetic component, explained Dr. Steven Poceta, a neurologist affiliated with the Scripps Clinic Sleep Center in San Diego who has documented cases of sleep eating, driving, and cooking among other behaviors.

    While science hasn’t figured out why many children sleep walk, but outgrow it, it does appear that the habit can return during times of stress. “That’s a very common scenario,” Poceta said.

    Sleep deprivation caused by apnea, or restless leg syndrome, can lead to sleepwalking. So can drugs like zolpidem (Ambien), which became infamous for leading to sleep eating. As for how often that happens, Poceta said, “we think it is more common than is fully appreciated.”

  • Forget white noise. 'Pink noise' will help you sleep better

    By Markham Heid, Prevention

    You've probably never been jealous of an elephant, but you're about to be. Elephants need only three to four hours of sleep per night in order to be their happy elephant selves during the day. So what's Dumbo's secret? Deeper, more stable sleep--and new research may have found the secret to helping you achieve elephantine-levels of repose each night: Pink noise.

    You've likely heard of "white noise," says study author Jue Zhang, Ph.D., an associate professor at China's Peking University, which is produced when the sounds of different frequencies are combined. Pink noise, on the other hand, is a type of sound in which every octave carries the same power, or a perfectly consistent frequency, Zhang explains. "Think of rain falling on pavement, or wind rustling the leaves on a tree," It's called pink noise because light with a similar power spectrum would appear pink, he says.

    Top 10 Sleep Thieves

    To see how pink noise would affect human sleepers, Zhang and his team recruited 50 people and exposed them to either pink noise or no noise during nighttime sleep and daytime naps while monitoring their brain activity. The results: An impressive 75% of study participants reported more restful sleep when exposed to pink noise. When it came to brain activity, the amount of "stable sleep"--the most restful kind--increased 23% among the nighttime sleepers exposed to pink noise, and more than 45% among nappers, says Zhang.

    What's going on here? Sound plays a big role in brain activity and brain wave synchronization even while you're sleeping, Zhang explains. The steady drone of pink noise slows and regulates your brain waves, which is a hallmark of super-restful sleep.

    To experience the benefits of pink noise in your own bedroom, Zhang recommends fans or noisemakers that produce steady, uninterrupted sound or that imitate falling rain or wind. You could also download an application that will play pink noise through computer speakers or your cell phone, such as the Perfect Sleep application. Just don't wear headphones, which can disrupt sleep, he says.

  • Why do so many of us hate black licorice? A few theories

    Getty Images stock

    When the American Licorice Company announced on Wednesday it was voluntarily recalling its black licorice Red Vines because of high levels of lead, about half the country paused and thought, “Wait, people eat black licorice?” The other half (presumably mostly curmudgeonly grandfathers and uncles) became disappointed to learn it would be harder than ever to find the sweet treat.

    Licorice, which comes from the root of Glycyrrhiza glabra plant, flavors what we call black licorice (which is redundant), liqueurs such as Jagermeister, and medicines such as NyQuil, which relies on the pungent flavor to mask the medicinal taste. Even though it commonly appears in products, licorice seems polarizing.

    “People either love it or hate it and, as far as I can tell, it’s not a learned like or dislike,” says Marcia Pelchat, an associate member of the Monell Chemical Senses Center in Philadelphia, a nonprofit center, which researches taste and smell.  

    “I don’t know a specific gene that is associated with liking and disliking licorice. [But] it does seem to be something that people are born with.”

    While experts haven’t conducted much research on licorice preference, Pelchat — who dislikes the flavor but is married to a lover of licorice — shares a few theories as to why licorice divides us between the lovers and the haters.

    When we eat, we use both the sense of taste and smell to detect flavor. Taste includes sweet, bitter, salty and sour. When we bite into a piece of licorice, we taste glycyrrhizin, a natural sweetener in licorice root, which can taste, to some, like saccharin, the artificial sweetener found in Sweet 'n' Low. With licorice, this sickly sweet lingers, causing some to wrinkle their noses in displeasure.

    “What this suggests to me is maybe liking and disliking licorice is related to liking and disliking saccharin,” Pelchat says.

    Licorice also contains anethole, which is aromatic and plays on our olfactory sense. Anethole also occurs in anise and fennel, both of which licorice haters might find more tolerable. (Anise and fennel flavor absinthe, for anyone who thought it, too, might be a licorice liqueur.)

    “[Taste] seems to be built-in; it doesn’t require any learning,” she explains, adding that people can train themselves to like spicy foods, or even cilantro. “However, responses to smells seem to be learned.”

    While this means people might dislike licorice because it reminds them of the smell of NyQuil, or another malodorous memory, Pelchat suspects that it’s really the taste, not the smell that turns people off.

    “There are lots and lots of genes involved in the perception of [flavor] and of aroma and we probably all have relatively unique sensory worlds. So that’s just something to keep in mind in talking about individual differences in preference.”

  • Why men are less likely to eat veggies

    Amy Neunsinger / Newscom stock

    A new study explores the reasons why men are less likely to eat fruits and vegetables than women.

    By MyHealthNewsDaily.com

    Men are much less likely to eat their veggies than women, and now researchers say they know part of the reason why.

    In a new study, men reported less favorable attitudes than women about the value of eating fruits and vegetables, and men also said they had less control over their fruit and vegetable intake than women did.

    The study showed that "men don’t believe as strongly as women that fruit and vegetable consumption is an important part of maintaining health," said study researcher John A. Updegraff, associate professor of social and health psychology at Kent State University in Ohio. It also showed that "men feel less confident in their ability to eat healthy foods like fruits and vegetables, especially when they are at work or in front of the television," he said.

    The findings suggest that messages that are effective in encouraging women to eat more produce don't work so well on men. "It's important to help men understand the importance of a healthy diet, as well as to develop confidence in their ability to make those healthy choices, whether it be at work or at home," Updegraff said.

    Fruits and vegetables, and beliefs
    In the study, Updegraff and his colleagues set out to look at whether an idea in psychology called "the theory of planned behavior" could explain what so many studies have shown — that men are much less likely than women to meet the daily recommendations for fruit and vegetable intake.

    This theory looks at the link between people’s beliefs, and their behavior, Updegraff said, and the researchers looked at three beliefs that should motivate people to eat nutritious food: their attitudes toward fruit and vegetables, their feeling of control over their diet, and their awareness that other people want them to improve their diet.  

    The researchers used data from nearly 3,400 people gathered as part of the National Cancer Institute's Food Attitudes and Behavior survey. The survey, conducted in 2007, included questions aimed at measuring people's attitudes, beliefs and behaviors regarding food. About 40 percent of those surveyed were between 35 and 54 years old.

    On the whole, the researchers found that women had more favorable attitudes toward eating fruits and vegetables. For example, women were more likely to agree that if they ate plenty of fruits and vegetables every day, they would look better, and live a longer life.

    Additionally, the researchers found that women reported greater confidence in their abilities to eat fruits or vegetables as a snack even when they were tired, really hungry, or around family or friends who were eating junk foods.

    Peer pressure doesn’t work
    While the theory of planned behavior is well-accepted among most health researchers, the new study is the first to use it to figure out why women consume more fruits and vegetables than men, Updegraff said.

    The findings suggest "some fruitful avenues" for improving men's diets, he said.

    "What might work best is teaching men ways to take control over their fruit and vegetable consumption," he said. For example, men could be shown options for eating healthy while at work, or how to better include fruits and vegetables in their in-front-of-the-TV snacks. 

    The study also suggested that one technique isn't likely to get men to eat better: peer pressure. "It turns out that this peer pressure is not a particularly strong motivator, for either men or for women," Updegraff said. In the study, men actually reported greater pressure than women from others around them to eat more fruits and vegetables, but still consumed less.

    The study was published online Aug. 13 in the journal Appetite.

  • How far back can you remember? When earliest memories occur

    Some are as cozy as a lullaby, like the 52-year-old melodic, moving picture inside Scott Rubel’s head of Joan Baez and her sister, Mimi, strumming guitars, “smiling like goddesses,” and personally serenading away his tears. In that moment, he was 3. 

    Others are sad, like the 43-year-old desperate pleas that still echo inside Lucy Boyd’s mind: she’s wrapped in her mother's arms as the woman begs her husband — Lucy’s father — not to leave their marriage. On that day, she was not quite 2.

    Our first palpable recollections — from vital, early mileposts to seemingly random snapshots of our toddler years — stick for good, on average, when we reach 3 1/2 years old, according to numerous past studies. At that age, the hippocampus, a portion of the brain used to store memories, has adequately matured to handle that task, experts say.

    In fact, a fleet of neural-engines are simultaneously revving to life at roughly that same age, including our verbal abilities and the revelation that we are each our own entities, says Julie Gurner, a Philadelphia-based doctor of clinical psychology.

    “We know that having language can be very important to memories because in having words for our experiences, we can talk about them, repeat them, and structure them,” says Gurner, who lectures on the brain’s anatomy and functions as assistant professor of psychology at the Community College of Philadelphia. “Around the age of three, we are also developing a distinct sense of self that allows you to distinguish who you are from the outside world.”

    Meanwhile, research continues to churn up evidence on how, why and when first memories are recorded.

    • Last year, researchers at Memorial University of Newfoundland in Canada reported that the earliest recollections of most grade-school children change or "shift" as they mature – and only by about age 10 are they finally cemented into those singular recollections that adults carry through life. That study was published in the journal Child Development.
    • Females seem to form their first permanent memories two to three months earlier than males and, for both genders, inaugural memories tend to be visual and positive rather than verbal or negative, according to a study published in journal Consciousness & Emotion in 2003.

    “Strong emotional events truly burn themselves into our memories — both the good and the bad,” Gurner says. “My experience tends to be about half of clients report positive and half report negative experiences. There is likely no one reason we can pinpoint why one person might retain a good memory and another person might retain a bad one. Psychologists are continuing to examine how our predispositions, traits, environment and biology factor into how we frame our own experiences.”

    For whatever reason, one lone moment has been selected and stamped in our brains as the first day our life experiences became worthy of mentally filing away and cataloguing. In a sense, they're our cognitive birthday.

    For Scott Rubel, that everlasting fragment comes with its own sweet soundtrack – provided by folk singer Joan Baez. That’s the first memory cherished by Rubel, who from age two to four lived on the campus of Redlands University in Redlands, Calif., where his dad was a student.

    One night in 1960, a classmate of his father took the family to dinner. En route, they stopped in San Bernardino at the Wigwam Hotel -- which featured an array of 30-foot-tall teepees -- to pick up two more friends: Baez and her sister.

    “I probably had seen a couple of John Wayne movies by then and the situation I found myself in seemed like a threat,” says the 55-year-old president of a custom stationery website who lives in Los Angeles. “I began to cry like a baby -- which I guess I was -- and my mother and father held me while the very kind and patient sisters took out their guitars.

    “I remember the visual of it clearly as I stopped crying and gazed at these two beautiful women, who [were] dressed almost the same in boots and black skirts with red tops and buckskin jackets," Rubel recounts. "Both had long super-black hair and were true entertainers."

    The duo sang and played “until I was calm,” he says, adding that he can mark his age at three years and nine months because he was told Baez had just performed at the Newport Folks Festival.

    On the other edge of the emotional spectrum, Lucy Boyd lugs a harsh first childhood memory – the crumbling of her parents’ marriage. During that horrible few minutes, Boyd can picture herself being held by her mother as the woman sat on a piano bench near the front door, beseeching her husband.

    “He said he was leaving and she was begging him not to go … I also always had an innate sense of, ‘This is important; I need to always remember this,'" says Boyd, 45, a registered nurse and author from Hixson, Tenn. She knows this occurred just before she was two because her parents divorced in 1968.

    Then, there are what seem like mundane first memories – stray threads of our past that seem to carry no special weight.

    Paula Pant, 28,  remembers sitting on her mother’s lap in their Cincinnati living room. She believes she was 2 years old at the time.

    “My mom was talking to a guest, one of her friends, who was sitting opposite us," says Pant, who now lives in Atlanta and runs a financial-advice site . "The guest wanted me to sit in his lap. My mom tried to put me in his lap. I started crying, so my mom reversed course, keeping me in her lap. That’s it. It’s a standard, everyday childhood event; nothing special or out-of-the-ordinary. There's no reason it would be seared in my mind as my first memory. And yet it is.”

    While such fragments might seem to lack any larger meaning decades later, often they do carry some form of subconscious heft, Gurner says.

    “This woman may only remember what she sees as an insignificant snippet of memory because it may be the only trace left of a memory that likely was more extensive at another time,” Gurner says. “Often, especially in early memories or before language, we have a hard time keeping our memories in a context. Our memories can fade, and if they do not disappear, sometimes we can be left with the bits."

    Gurner’s own first memory was notched, she says, at about age 2, taking place on the farm where she grew up. She is standing in her playpen, gazing out the window at a creature in the pasture. As she soaks in the image, her brain is flooded with questions and feelings of amazement because it is the largest single thing the girl has ever seen. The object: a horse.

    “That sense of wonder and curiosity has never left me,” Gurner says. “I believe that sharing a first memory is meaningful because it reveals something uniquely personal about us to others. It allows us to share a moment in time from a vantage point of a younger version of ourselves, and gain insight into the younger versions of someone else.

    “First memories get beyond the presentations of everyday life – of clothing, career and status -- and reveal something distinctly personal and unique about you … something about our families or environment," she adds. "But all of it has something that has been so resilient that it has withstood many years of other memories and experiences without erasure. For some it will be fun, for others, very painful – but for everyone, it’s personal.”

  • Why do so many women go blonde?

    By Emily Sohn, Discovery Channel
    Teen actress and singer Miley Cyrus wowed fans this week by chopping off most of her hair and dying it platinum blonde. Afterwards, she tweeted, "LOVE my hair ♥ feel so happy, pretty, and free."

    With the new 'do, Cyrus joined the throngs of women around the world who choose to go blonde.

    So, what's the appeal?

    NEWS: Blonde to Brunette: X-rays Reveal Artist's Switch

    At its root, the desire to have light hair represents an urge to look different, said Peter Frost, an anthropologist at Laval University in Quebec City. Most people have dark hair, so blondes stand out.

    The urge to be blonde may also be driven by deep evolutionary history beginning many millennia ago when light shades first appeared on women's manes, allowing them to turn the heads of potential mates.

    "The more common a hair color becomes, the less often it is preferred," Frost said. "It's a kind of novelty effect. The moment you become ordinary, you no longer have the same appeal. There's selection for being a bit different and eye-catching."

    Modern humans evolved in Africa. Even after migrating to Europe about 35,000 years ago, scientists think that all people had black hair. Then, sometime between 10,000 and 15,000 years ago in northern and eastern Europe, studies suggest, the hair-color gene MC1R developed variations that produced a diversity of hues, including red, brown and blonde.

    NEWS: How Hair Turns Gray

    Eye color, which is controlled by several genes, including one called OCA2, diversified at the same time. Some researchers have speculated that lighter hair and eyes helped people better acquire vitamin D in a high-latitude environment. Frost has a different theory.

    During the last Ice Age, he proposes, men had to travel longer distances through Arctic tundra to find animals to hunt. That led to higher death rates for men as well as a decreased chance for polygamy because it would have been nearly impossible to support more than one family with such a scarcity of food.

    As women came to outnumber the supply of monogamous men, they had to become more competitive for male attention. In evolutionary terms, this produced strong sexual selection for novel hair and eye colors. Women with unusually bright looks were eye-catching and appealing.

    Men didn't experience the same pressure, which might explain why it is still more common for women to be born blonde, and why it takes longer for blonde hair to darken on girls than it does on boys.

    Even today, Frost said, the market for blonde hair dye is greater among women in places like Latin America, where naturally light locks are particularly unusual. In Sweden, where a large proportion of people are blonde, women often darken their hair. Purple, magenta and other unusual hues have also become popular.

    In addition to the desire to stand out, going blonde might represent a subconscious attempt to look young and cute. That's because, along with broad foreheads and little noses, blonde hair is also more common in young children than in adults.

    All of that hair coloring may pay off for women, suggests some research. In a study published in April in The Journal of Socio-Economics, for example, French waitresses earned more money in tips from male customers if they wore blonde wigs.

    Other research, which included more than 12,000 American men using a popular dating website, found that men showed a slight preference for blondes over other hair colors, said Jena Pincott, author of the book, "Do Gentlemen Really Prefer Blondes?: The Science Behind Sex, Love, and Attraction." Polish men have been shown to prefer blonde hair on women who are older than 25, a finding that supports the youthful-look theory.

    For modern women, the benefits might be psychological more than anything else.

    "If being a blonde makes you feel more attractive, you'll be more confident, seek more attention, and likely get it," Pincott said. "Then you'll have more fun."

    Once blonde hair becomes too common, though, it may lose some of its appeal.

    Some research has shown that single men prefer pictures of blonde women if embedded in a series of brunettes. But if the men see mostly blondes, brunettes become more attractive to them. Scandinavian men, who are surrounded by blondes from birth, often say they prefer women with darker hair.

    "Modern men are attracted to blond hair for the same reason as their Ice Age counterparts: It's eye-catching and, much of the time, rarer," Pincott said. But, she added, "Even the most dazzling shade won't help you stand out if everyone has it."

  • Antibiotics may help make you fat, studies show

    AP

    A clump of Staphylococcus epidermidis bacteria (green) in the extracellular matrix, which connects cells and tissue, taken with a scanning electron microscope. At right, the bacterium Enterococcus faecalis, which lives in the human gut, is just one type of microbe that live on your skin, up your nose, in your gut; enough bacteria, fungi and other microbes that collected together could weigh a few pounds. (AP Photo/National Institute of Allergy and Infectious Diseases (NIAID, Agriculture Department)

    Could antibiotics make you fat?

    Two studies this week suggest that using antibiotics may save people’s lives, but could also change their metabolisms. Put together, the studies suggest that taking antibiotics might alter digestion to help people absorb calories from food they normally would be unable to digest.

    Every human carries pounds of microorganisms that we couldn’t live without. They break down food and extract nutrients like Vitamin K for us. Antibiotics will kill some of these beneficial organisms, which is why so many doctors now tell patients to eat yogurt after taking a course of the drugs, to replace some of the good guys.

    “There is emerging evidence suggesting the importance of the microbes in our intestines and their role in absorbing food,” said Dr. Leonardo Trasande of New York University, who led one of the studies.

    The two studies look at different sides of the coin, and help answer two questions -- whether antibiotics really do affect how we absorb nutrients, and how they might do so. Together, they support the idea that the drugs kill off some populations of bacteria and allow microbes to flourish that are very good at getting calories out of hard-to-digest plant foods.

    Trasande’s team looked at the medical records of more than 11,000 newborns in Britain, who were carefully followed after they were born in the 1990s. The babies who got antibiotics before they were 6 months old were 22 percent more likely to be overweight by the time they were 3 years old, the team reported in the International Journal of Obesity. If they got antibiotics later in childhood, there wasn’t a strong effect – something that could suggest the antibiotics changed the balance of the microbes as they were just setting up shop in the infants. Babies are born with sterile digestive tracts, and they acquire bacteria, yeast and other microorganisms mostly from their mothers. The germs are collectively called “flora” by scientists.

    “They play key roles in immune functions, among other things,” Trasande told NBC News. “Antibiotics disrupt the development of the healthy flora in our gut. The earlier the exposure occurs, the more disruptions occur,” Trasande says. “It seems the first few days and months are important. It is difficult to reconstitute that in later life.”

    The other piece of the puzzle is whether it’s the antibiotics or something else that is doing this. Dr. Martin Blaser of New York University has been studying the effects of antibiotics on the body for years. A second team he heads has been studying what happens if you feed antibiotics to animals.

    They wanted to replicate what farmers have known for decades -- that giving low doses of antibiotics to farm animals make them fatter. Many experts had thought the drugs were keeping the animals from getting infections and making them healthier, but Blaser suspected something else was going on.

    When his team gave mice low doses of antibiotics long-term, the mice got fatter even though they weren’t eating any more than other mice. This, they report this week’s issue of the journal Nature, suggests the antibiotics somehow make the mice absorb more calories from their food.

    “We have other work that is in process that continues to confirm and extend this,” Blaser said. “That work shows that giving antibiotics early in life, similar to what farmers do in their farm animals, is changing metabolism in mice and making them bigger and fatter.”

    The gastrointestinal tract is also the center of hormone production, the researchers said. It’s possible altering the organisms in the intestines – called the microbiome -- could help people better absorb nutrients and calories from “indigestible” foods such as cellulose.

    The second NYU team gave the mice varying combinations of the antibiotics penicillin, vancomycin and chlortetracycline. Mice that got the antibiotics piled on more fat than other mice, even though the fatter mice did not eat more. Also, their poop had fewer calories – suggesting they were absorbing more and eliminating less.

    Other mouse studies being done by Blaser’s team show that giving antibiotics to mice every once in a while -- akin to giving antibiotics to a child to treat ear infections -- also alter the gut bacteria.

    So does that explain why people are getting fatter? Does every dose of antibiotics kill off some bacteria, allowing the energy-efficient species to move in and squeeze every calorie out of an apple peel or bowl of high-fiber cereal?  

    “That’s at least one of the mechanisms,” says Blaser. But he notes that studies in people suggest it’s doses very early in life that matter most, just as various colonies of bacteria are getting established in the colon and intestines. And there’s an effect on the immune system, too. Other studies show that changing the balance of bacteria effects immune cells known as T-cells – something that may someday help explain links between diet and diseases such as inflammatory bowel diseases and perhaps even colon cancer.

    In other words, it is too soon to say whether a 5-day prescription of Zithromax for strep throat could make you fat.

    “A lot of things are interconnected,” Blaser says. “Obesity is multifactorial. I am not saying antibiotic effects on the microbiome are everything but our work suggests it is contributory. Whether it’s 10 percent or 70 percent, we don’t know yet.”

    Another big missing piece of the puzzle: Which species of bacteria are the most important? People have trillions of bacteria in and on their bodies. Microbes outnumber human cells by a factor of at least 10 to one and scientists believe at least 10,000 different species live in and on us. Healthy colonies of microbes not only process vitamins, but maintain pH balance on the skin, prevent tooth decay and even protect against infections. So which ones are killed by the antibiotics, and which do we want more of? No one knows yet.

    “We are just beginning to scratch the surface,” said Dr. Ilseung Cho, who worked on the study in mice.

    While it is important not to use antibiotics when they are not needed, the researchers stress that they do save lives. “I wouldn’t rush to come off any antibiotics right now,” Cho cautioned.

    It’s also not clear if food like yogurt, called probiotics, help much. “There is a concept called prebiotics,” Cho said. “It is essentially introducing nutrients into your digestive tract that would select for particular bacteria. Then you might be able to alter the bacteria.”

    Prebiotics are found in plain old food such as soybeans, jicama and raw oats, all of which are rich in compounds such as inulin, which people cannot digest, but which certain bacteria love.

  • Spacing out for a bit can boost your memory

    By Ashley Insalaco, Men's Health
    Next time you zone out when your girlfriend is talking to you, just tell her you wanted to remember what she was saying longer. Wakeful resting--or zoning out--after learning something new can boost your memory, according to a study published in Psychological Science.

    In the study, researchers told two short stories to 33 people. After one story, the participants sat in a room with their eyes closed. After the second story, they played a computer game. Seven days later, the people who zoned out were able to recall more of the story details. After learning something new, your brain automatically replays the information to form a new memory. But learning something new interferes with this process, the study explains.

    Your move: When you learn something new, close your eyes and take a break. You can review what you just learned, think about what you're having for lunch, or replay the events of last night's date--just don't take in any new information. For more ways to improve your memory, check out these 27 Ways to Power Up Your Brain.

  • Banish brain freeze: New study shows how

    Getty Images stock

    By K. Aleisha Fetters, Women's Health

     

    It's a sweltering summer day, so you take a big sip of a refreshing, frozen coffee--and you're immediately doubled over with throbbing head pain.

    Why do frosty foods give us headaches? New research has shed light on the possible causes (and cures) of the phenomenon known as brain freeze.

    When a frozen treat comes in contact with the roof of your mouth, it triggers nerves that alert your brain of the temperature change. In response, the anterior cerebral artery dilates and increases blood flow to the brain's frontal lobe to help keep it warm and protected, says Jorge Serrador, M.D. of Harvard Medical School, lead researcher on a recent study which identified the mechanisms at work during what's commonly called brain freeze.

    Researchers believe that the additional blood flow to the frontal lobe increases pressure in the skull, which brain receptors process as pain. This could explain why the frontal lobe is the area of the brain that feels "frozen" post-popsicle, Serrador says.

    Here are three ways to avoid the big chill:

    1. Tongue It
    Can you curl your tongue? Good. Fold the tip of it backward and stick the bottom of your tongue to the roof of your mouth. The warmth will help heat up the nerves in your palette and cause the blood flow to your brain to normalize, Serrador says.

    2. Slurp Slowly
    To make study participants get brain freeze, Serrador had them suck down ice water like thirsty maniacs. Why? "The only way to get a brain freeze is to drink or eat whatever it is [that's cold] really fast," he says. If you drink (or eat) more slowly, you give your blood time to heat the tissue in the roof of your mouth and avoid triggering a cold-induced headache. So slow down and savor your treat.

    3. Warm Your Hands
    Your hands might not be cold, but acting like they are can make your mouth warmer, Serrador says. Cup your hands around your mouth like you would in the winter and exhale deeply. It will trap warm air in your mouth and help thaw your noggin.

  • Shy people are better at reading facial expressions

    By Rachael Rettner, LiveScience

    Shy people may be hesitant to look you in the eye, but they seem to have a superior ability to recognize certain facial expressions, a new study suggests.

    In the study, college-age adults who were shy were better able to recognize expressions of sadness and fear compared with those who were not shy.

    The findings were surprising, said study researcher Laura Graves O'Haver, a doctoral student at Southern Illinois University at Carbondale, given that previous work has found shy people tend to misinterpret facial expressions. However, this earlier work was typically performed on children, and the ability to recognize facial expressions may change with age, Graves O'Haver said.

    The new results put a positive twist on a trait that is usually considered unfavorable, she said.

    "We tend to give shy people a bad rap," but the new study suggests there are some strengths to being shy, Graves O'Haver said. "It might be nice to focus on those strengths."

    Graves O'Haver presented her findings this month at the American Psychological Association meeting in Orlando, Fla.

    Graves O'Haver analyzed information from 241 college students (average age of 19) who took an online survey. Participants were shown 110 pictures of faces and asked to identify the facial expression represented by each picture (happy, sad, anger, fear, surprise, disgust and a neutral expression.)

    To determine their level of shyness, participants were also asked whether certain statements were true for them, such as "I feel tense with people I don’t know well," "I find it difficult to ask for information," and "I'm uncomfortable at parties." [ Life's Extremes: Outgoing vs. Shy ]

    Overall, people were able to identify the facial expressions quite well, with an 81 percent accuracy rate.

    People with high levels of shyness were more accurate at identifying facial expressions of sadness and fear than those with low levels of shyness.

    When asked how they were feeling during the study, shy people were more likely to be in a negative mood. This could, in part, explain the results, because studies have found that people in a bad mood tend to see other things in a negative light, "kind of like the opposite of rose-colored glasses," Graves O'Haver said.

    It's also possible the superior ability to recognize sad and fearful facial expressions can contribute to people's shyness, Graves O'Haver said. If shy people see negative emotions on people's faces to a greater degree, "that could make you feel shy," Graves O'Haver said. "You might want to limit how much you look at faces," she said.

    However, Graves O'Haver stressed the study only shows an association, and not a cause-effect link.

    And because the study was conducted online, it's not clear how well the results would translate to a real-world situation, Graves O'Haver said. She would like to conduct another study in which the experiments more closely resemble a real-life conversation, perhaps through using videos instead of pictures.

  • Could you go 10 weeks without lying?

    Getty Images stock

    We tell one lie, sometimes two, every day, sharing an average of 11 untruths per week. We tell lies to avoid hurt feelings, or we embellish to make a story more interesting. 

    But whether it’s a white or boldface lie, all these fibs harm our health. Researchers discovered that people who lie less experience better physical and mental health than those who commonly bluff.

    “If I could establish a link between better health and lying, maybe people wouldn’t [lie so much],” says Anita Kelly, a professor of psychology at the University of Notre Dame.

    As an expert in secrecy, Kelly had known that people frequently lie and also value honesty in others. Fascinated by this paradox, she wondered if people could stop lying and how it would impact their health and relationships.

    Kelly divided 110 participants, ages 18 to 71, into two groups: a control group, who could go about their lying lives as usual, and a “no lie” group, who were instructed to refrain from all lies, whoppers and white alike, for 10 weeks. Once a week over the 10 weeks, subjects answered questions about their health, sometimes while connected to a polygraph machine. Both groups knew they would be answering questions about the number of white and major lies they told but the no lie group were also instructed not to fib (and they even signed a contract stating they wouldn’t).  Being hooked up to a polygraph machine meant the no lie group couldn’t lie about the times they'd, well, lied; if they did lie during the week, they had to admit it (telling no lies has a learning curve; despite best intentions, the no lie group still fibbed). 

    “The irony is that now that we have more outlets for disclosure [such as Facebook], it forces us to lie more because now people ask really bold questions,” she says.

    When people refrained from sharing white lies, weekly they experienced three fewer physical ailments such as sore throats or headaches. And, their minds were at ease -- avoiding little fibs led to four fewer reports of mental anguish, such as depression and anxiety.  

    Giving up a bluffing habit wasn’t easy. The non-liars had to consciously think about what they were saying. When they first tried 24/7 honesty, they still told a few lies a week, but not as many as the control group.  

    “Depending on the participants, some found it very easy to drop to zero [lies]; some did drop to zero. It still was, on average, one lie in the non-lie group,” she explains.

    In her daily life, Kelly tells as few tall tales as possible. She once discovered a dead chipmunk prior to a meeting and she struggled to dispose of it, making her tardy. Because she’s known for her honesty, no one doubted her.

    Kelly stresses that not lying doesn’t mean sharing harsh truths -- it means telling kind truths or not revealing some information. A kind truth might sound like “I loved how that other dress looked on you,” instead of “you look terrible in this dress.” Participants in the no lie group also avoided exaggerations by changing the subject or not answering questions, politely, of course.

    In addition to reporting less anxiety and depression and improved physical health, the no lie group felt happier in their relationships.

    “Good relationships have long been connected to good health,” says Kelly. “The bottom line is this is really about the relationships … being caught in these lies is anxiety [producing] because we don’t want to ruin the relationships.”

  • Brain function remains sharp in rare 'SuperAgers'

    Scientists have long assumed that fading memories are just a normal part of aging. But a new study suggests that certain 80-somethings can remember every bit as well as people much younger.

    Researchers from Northwestern University found that these mentally sharp octogenarians, dubbed SuperAgers, also have brains that look very much like those of people in middle-age, according to the study published in the Journal of International Neuropsychological Society.

    For the new study, researchers used MRIs to look at the thickness of the outer layer of the brain, a region called the cortex, in SuperAgers, normally aging 80-somethings, and healthy 50- to 65-year-olds.

    What they found was intriguing – the SuperAgers had brains that looked very much like those of the younger people in the study and in some ways looked even healthier. 

    "We were very surprised at that," says study co-author Emily Rogalski, an assistant research professor at the cognitive neurology and Alzheimer's disease center at the Northwestern University Feinberg School of Medicine

    "When we looked at cortical thickness, we were very shocked to see that even with a 20- to 30-year age gap, there was seemingly no difference in the cortical thickness," she says. "In normally aging 80-year-olds, you see quite a bit of cortical thinning, even among those who are still performing normally for their age."

    The cortex is key since it's involved in memory, attention, and complex thinking, also known as executive function.

    Rogalski and her colleagues tested the memories and cognitive skills of 12 Chicago-area SuperAgers and 14 middle-aged volunteers. They then scanned all 26 with a 3D MRI machine and compared both groups of scans to images from normally aging 80-somethings that came from a national data bank.

    Finding a group of SuperAgers was no easy task, however.

    While plenty of 80-somethings showed up at the lab saying their memories were great, most didn’t remember as well as healthy middle-aged people do.

    "We weren't even sure if we would be able to find any SuperAgers since we set the bar so high," says Rogalski. "They had to be as good as 50- to 65-year olds. We screened 300 people who thought they had good memories and found 30 SuperAgers."

    And the MRIs showed why the 30 SuperAgers were so mentally sharp.

    Rogalski found the SuperAgers' cortexes were as thick as those in people 20 to 30 years younger.

    Experts believe that shrinking cortexes are a sign that cells are shriveling and dying with age - sometimes killed off by the same abnormal proteins as you see in Alzheimer's brains. One finding that really surprised Rogalski and her colleagues: a region deep in the brain, called the anterior cingulate was actually larger in SuperAgers than it was in middle-aged folks.

    The anterior cingulate is very important for attention. Studies have shown that one of the reasons memory fails as we age is that we can't focus as well as we did when we were younger.

    "If I were to tell you ten things you need to pick up at the grocery store and then the phone rang and you got distracted talking to your best friend you'd probably find it hard to remember those ten things when you got to the store," Rogalski explains. "That wouldn't mean your memory was bad, but rather, that you weren't able to focus on the task."

    Rogalski hopes the new research on SuperAgers may help scientists unlock the secrets of these "youthful brains" and find ways to protect us against from age-related damage.

    "This is the first step in a new way of looking at this - a road less traveled in aging research," she says. "Instead of looking at what is going wrong with the brain, we want to know what is going right."

    As for why some people are SuperAgers and some aren't, the research team can't provide any answers at this point. It could be all related to genetics or a combination of genes and the environment: no clues popped up during the SuperAger's interviews that set them apart from people who had aged normally.

    But the question of whether there's something we can do to keep mentally sharp is something Rogalski is hoping she'll be able to answer as she continues to study the SuperAger phenomenon.

  • The science of spite, explained

    By Trevor Stokes, LiveScience 

    Most people aren't spiteful, but given the opportunity, those with malice lash out to produce the maximum harm, new research suggests.

    In the study, researchers used an eBay-like setup where student participants could raise the prices others would pay for items, without necessarily winning the auction. People consistently chose to be vengeful or kind, with little in between, the researchers found.

    "We were surprised by how stark the distribution of spitefulness was," study researcher Erik Kimbrough, an economics professor at Simon Fraser University in Canada, told LiveScience. "People either go all out or they don't act spiteful at all."

    Why spite — petty ill will in an effort to annoy or hinder another — exists has puzzled psychologists, evolutionary biologists and economists, but seminal work in the early 1960s by W. D. Hamilton suggested that an individual may help those more closely related pass on their genes by selectively harming others. [ The 10 Most Destructive Human Behaviors ]

    The current study identified a bipolar (all or none) distribution of spiteful behavior, but in the majority of cases (70 percent), participants were consistent in their level of kindness or spitefulness.

    The research team originally wasn't looking for spiteful behavior at all, but instead was trying to figure out why people tend to overbid during online auctions compared with set "buy-it-now" prices.

    "The result that we found about spite was accidental," Kimbrough said.

    In the experiment, bidders put in their first offer and before the second round started, the highest bid gets revealed. Any highest bidder wins the item at the second-highest bid price — which gives the researchers wiggle room to determine how spiteful bidders would act during the second round of bidding.

    During the second round, participants could raise their bids to win the item, but spiteful participants could use the highest bid information to drive up prices and ensure they weren't the highest bidder (making sure the "winner" had to at least shell out more money for the item). Bidders were also given the choice to try to win the item or to keep their original bid. A total of 48 participants underwent 16 auction rounds during the experiment.

    Those who chose spiteful responses could do so by: not winning the auction (minor spite), driving up the price and still losing the auction (abundant spite), and increasing the price as much as possible without winning the auction (maximum spite).

    Nearly a third (31 percent) of all spiteful actions were to the maximum effect; and the majority of the remaining spiteful events (68 percent) were defined as abundantly spiteful.

    Whether or not the results can be explained by evolution, which would suggest there is some sort of advantage to being spiteful, is up for debate. Evolutionary biologists define spite as an action that harms or reduces the fitness of both the spiteful person and their victims.

    "It's not clear how to translate the payoffs of the human experiments into these Darwinian fitness terms," Andy Gardner, zoology fellow at the University of Oxford, wrote in an email to LiveScience. Gardner was not involved in the study.

    "There's a danger of over-interpreting these kinds of studies, reading an adaptive rationale into the behavior where none exists," Gardner wrote. "This is like how moths are attracted to lamps when it's dark -- there's no benefit to the moth in doing this, and the behavior evolved (to let the moths use the moon's light for navigation) at a time before there were lamps in the moths' environment.

    "However, it is interesting, from a psychological point of view, to know that people do seem to enjoy inflicting harm on others, even when this incurs costs for themselves.

    To understand the behavior better, the researchers interviewed several participants afterwards and Kimbrough said the responses were a mixed bag.

    In some cases, spiteful participants told researchers they wanted to punish bidders for bidding too high or to teach them a lesson.

    "The rationale that they wanted to teach a lesson didn’t hold any weight because there wasn't an opportunity to change their first bids, they were already submitted," Kimbrough said.

    In a minority of cases, participants changed their behavior to become more spiteful. "It's not exactly clear why; it could have been impatience," Kimbrough said.

    Though the study helped to quantify spite, the motivations behind the behavior remain complicated. In one case, Kimbrough tried to be helpful by giving out directions to a couple taking a driving trip in California. “After they drove off, I realized I gave them wrong directions,” Kimbrough said.

    The journal PLoS ONE published the study Aug. 15.

  • Sleepwalking writer uncovers the mysteries of slumber

    Consider yourself lucky people if you’re one of those people who fall asleep easily, and stay asleep until the alarm goes off. Not so for David K. Randall, author of the new book "Dreamland: Adventures in the Strange Science of Sleep."

    Three years ago he woke up one night and instead of rolling over in his bed, he found himself in his hallway with a bruised knee and back.  It’s not like Randall’s loving wife kicked him out of the sack. Instead, he’s among the one in seven Americans with a long-term sleep disorder. Randall talks to NBCNews.com about the state of sleep research, why some of us just can’t seem to get enough  Zzzzzs, and also about those sometimes humorous, but more often dangerous, nighttime rambles.

    Q: It stands to reason that finding yourself in your hallway instead of your bed was pretty much of a “eureka” moment in terms that something was wrong with you.

    A: Absolutely. I went to my doctor and basically said that I didn’t want to run into another wall, so what can be done to help me. He said that they really didn’t know much about sleep, so just try and take it easy. This was the summer of 2009, and was the first sleepwalking episode that I had that I was actually aware of. I probably had more.

    I know I used to laugh and sing and talk in my sleep all the time. But being mobile really freaked me out. I wanted to find out more about sleep, and after I started working on the book I found that sleepwalking could be due to stress, depression, accumulated lack of sleep, or even have a genetic component. I realized my dad told me that he was a sleepwalker. He grew up on a farm in Kansas and once found himself in a corn field, which sounds more like an alien abduction, but it was a sleepwalking episode. So it’s probably in my genes.

    Q: Science recognizes some 75 sleep disorders, yet you say science really doesn’t know that much about sleep.

    A: Well, actually, most studies are actually focused on sleep deprivation, rather than just sleep itself. We know that lack of sleep, for example, can cause a lot of issues from high blood pressure and diabetes to poor work or athletic performance, among other problems. But science still can’t answer the basic question on why we need to sleep. I was really surprised by that.

    Q: So what do we know about sleep deprivation?

    One study showed that rats will die from sleep deprivation after 11 days. That’s a terrible way to go. The most extensively documented study on a human was done in the 1960s when a subject went without sleep for 11 days. He developed paranoia, delusions, hallucinations, and problems with short-term memory.

    Q: But most of us don’t go without sleep for 11 days. We turn to medications even if we have one lousy night of sleep. What’s your take on pharmaceuticals?

    A: I think there’s a two-part issue. First, with over-the-counter aids, some people take them every night, when they are supposed to be used short-term. Then, while there may not be a physical dependency, there is a mental dependency.  Prescription drugs, like Ambien and Lunesta, really don’t have that great of an effect. Studies show they may make you go to sleep 10 minutes earlier and sleep 10 minutes longer. That’s it. Plus, potential drug side effects like sleep eating and sleep driving, for example, aren’t a lot of fun.

    Q: Everyone blames a sleepless night on modern-day stressors like a bad economy, a bad job, a bad fill-in-the-blank. So did our ancestors sleep better?

    A: Maybe. But it’s kind of hard to say how sleep was for people in 500 A.D. when they probably slept on straw or were afraid of being eaten by some animal. But what we do know in pre-industrial times, people would sleep for a few hours, wake for an hour around midnight, and then go back to sleep until daybreak. Studies show that if people are deprived of artificial lighting, they will naturally sleep in this pattern. There’s been some work that shows that our gadgets like TV’s, computers, cell phones, and computer tablets are helping to destroy our sleep patterns.

    Q: What about dreams? Is that still looked at as voodoo science?

    A: I had a dream researcher tell me that he still gets weird glances from colleagues who think the work is a little to “new agey.”  I never used to think dreams meant anything, now I’m not so sure.

    Q: Why not?

    A: There are some studies showing our dreams are pretty true to life, minus the logic of the dream world, which can be very strange.

    Researchers know that we tend to dream of things that make us anxious, and most dreams are unpleasant. That could be due to the fact that nothing else is competing for our attention when we’re dreaming. And letting our minds experience some anxious moment while dreaming could possibly function as a dress rehearsal for life. Plus, there is some work showing that that dreams could possibly play a role in how we pick up a new skill or come up with a solution to a problem.

    Q: How are you sleeping now?

    A: I think sleepwalking will be with me my whole life. But then again, I also have a two-month old son. So I’m not sure I’m going to get a good night’s sleep until he’s about 18.

  • Study details how to avoid the weirdo on the bus

    Toby Burrows / Getty Images file

    Maybe it was the guy who hit him on the head with an umbrella because he was writing on his laptop. Or maybe it was the strange woman who took his picture, then followed him to work because she was smitten with him. Or maybe it was the gentleman who pooped his pants.

    Whatever the case, daily bus rider Jonathan Shipley has come up with a number of tactics to avoid sharing his seat with questionable commuters.

    "You have to have strategies when riding public transportation," says the 38-year-old writer from Seattle. "You don't want to be at the whims of fate because fate will undoubtedly stink and/or shout at you."

    Instead of trying for his own seat, for instance, he'll often sit next to an old woman. "Old women rarely stink," he says. "Old women are rarely crazy."

    Other strategies include putting a bag on the empty seat beside him, pretending to be asleep and flopping halfway onto the next seat and avoiding both the very front and the very back sections of the bus, which are often occupied by what he terms either "nutjobs" or "hooligans."

    Odd as it sounds, Shipley's tactics are right in line with those discovered by Yale University's Esther C. Kim, a Ph.D. candidate in sociology who recently published a paper in the journal Symbolic Interaction regarding the lengths commuters will go to avoid sitting next to each other on public transportation, something she refers to as "nonsocial transient behavior" or NTB.

    "Nonsocial transient behavior is basically an active effort to avoid other people," says Kim regarding these unspoken commuter acts. "The difference between simply not paying attention to someone and nonsocial transient behavior is the active, calculated way of deterring strangers from engaging in any kind of social interaction."

    For her research, Kim took a series of cross-country Greyhound bus trips over the course of two years, observing behaviors and talking to passengers about their commuting experiences. Some of the tactics for fending off fellow passengers she saw included people who would fall asleep, pretend to be busy by checking their phones or rummaging through their bags or don a "don't bother me face," which she calls the "hate stare."

    Other common tactics for avoiding a seatmate -- particularly what fellow passengers referred to as "the crazy person" -- included making no eye contact, stretching out legs to take up both seats, putting a coat on the seat to make it appear that it's already taken and simply lying and telling people that someone's already sitting in the seat.

    Kim says NTB is rooted in our desire to keep ourselves safe and comfortable and that it's not necessarily limited to buses.

    "This type of behavior can be seen in any place -- even at a public park where someone may not want to share their public bench," she says.

    She adds that nonsocial transient behavior stems from our frustrations about having to share a "small public space together for a lengthy amount of time." Although on Greyhound bus rides, other factors such as the passengers' transient nature, fear of potential danger, physical exhaustion and confinement in a small space without privacy also cause people to actively disengage, she says.

    Along with avoidance behaviors, the researcher also noted big commuting no-nos, such as sitting next to someone when other seats are available, which one passenger said immediately branded you as "weird."

    As for how to deal with the occasional stinky commuter, Shipley says he puts antibacterial lotion on his hands to mask the smell or wears loose tops that he can stretch up over his face.

    "In winter, I'm a fan of the turtleneck just for that reason," he says. "Turtlenecks are terrible for fashion, but great to breathe through on public transportation."

  • Goose bumps are a natural lie detector

    By Jennifer Viegas, Discovery Channel
    Goose bumps often turn out to be a skin orgasm of sorts, frequently resulting from an emotional climax stimulated by a "powerful other," according to new research.

    A study exploring the scientific and social aspects of goose bumps finds that this common form of piloerection is associated with feelings of awe. This physical reaction also cannot be faked.

    BLOG: Eye-Tracking Method Detects Lies

    The study, published in the journal Motivation and Emotion, helps to explain how a defense mechanism protecting the body from cold also surfaces during moments of wonderment.

    "We suggest that goose bumps may be the initial reaction: a blend of fear, surprise and defense, which is displaced by a positive appraisal made even more positive by the contrast from bad to good," co-author Richard Smith told Discovery News.

    Goose bumps come at the intersection of our fight-or-flight response, even if the emotional jolt arises from something as seemingly harmless as a musical performance, Smith, a professor in the University of Kentucky's Department of Psychology, explained.

    "[The] powerful other has the capacity to harm, but does not, assuming our submissive response," he said. "An initial 'fight' response, after a subsequent positive appraisal, precludes a 'flight' response. This positive response may be made all the stronger by the contrast."

    WATCH VIDEO: Can you REALLY tell if your friend is lying to you? As it turns out, probably not.

    From a physical standpoint, goose bumps occur when the muscles underneath the skin contract, making the individual's hair stand on end. This is useful for the survival of animals with skin fur or hair, the authors note, since goose bumps aid in the retention of body heat. This explains why we get them when exposed to sudden cold.

    Goose bumps are also, however, associated with intense emotional moments.

    For the study, researchers had participants keep a four-week journal making detailed entries each time they experienced goose bumps and rating their feelings during such moments.

    NEWS: The No-Fear Woman (And What Her Brain Reveals

    Awe was the second most-cited response as a cause of goose bumps, followed by reactions to cold. The intensity of goose bumps was also positively correlated with awe, but negatively correlated with envy.

    The absence of goose bumps with envy is notable, since both awe and envy are emotions that can result from observing, or otherwise experiencing, a powerful other. Awe, however, should stabilize social hierarchies while envy should undermine them.

    Jonathan Haidt, a professor of business ethics at the NYU Stern School of Business, along with colleague Dacher Keltner, has extensively studied awe. This feeling may have its origins in the emotional reactions to powerful, and thus potentially dangerous, leaders, explained Haidt, who told Discovery News that the latest findings about awe and goose bumps make sense.

    "The fear aspect may be, in part, what connects awe with goose bumps, in addition to a general effect of there being a rush of emotion," Smith said.

    "Following the local evolutionary psychologists, and the thinking of Haidt and Keltner, we emphasize the adaptive nature of social hierarchies, which arguably can only operate successfully if subordinates are willing to be submissive in the presence of the more powerful," Smith added. "If goose bumps foster awe in response to powerful others, which means a positive appraisal, then they work to support social hierarchies."

    Other research links goose bumps to the stimulation of the sympathetic nervous system, tied to the fight-or-flight reaction. Such an emotional rush can affect cerebral blood flow associated with reward, motivation and arousal. Since the reaction is akin to a mental reflex, awe-triggered goose bumps cannot be faked.

    Goose bumps are then like a natural lie detector test. Truthfully sharing our experiences with them can have the added benefit of strengthening bonds with others.

  • Are owners of certain dog breeds more aggressive?

    Rottweiler owners may be more likely to be aggressive than owners of Labrador retrievers, according to a new study.

    Stephanie Pappas, LiveScience

    Your canine companion might be saying more about you than you realize, new research finds. 

    Owners of stereotypically aggressive dog breeds such as German shepherds and rottweilers are more likely to be hostile and aggressive themselves compared with owners of typically laid-back pooches such as Labrador retrievers, according to a new study. 


    In this study, aggressive dog-breed owners scored higher in the personality trait of psychoticism, which is marked by anger, hostility and aggression. (Psychoticism is different than psychopathy, a personality disorder characterized by manipulativeness and lack of empathy.) 

    "This might imply (although has yet to be proven) that people choose pets that are an extension of themselves," study researcher Deborah Wells, a psychologist at Queen's University Belfast, told LiveScience in an email.

    Dogs and personality
    The research, published in the October 2012 issue of the journal Personality and Individual Differences, is not the first to find personality differences in dog owners based on breed. Toy-dog owners, for example, score high on the personality trait of openness, characterized by appreciation of new experiences, according to a study presented at the British Psychological Society annual conference in London in April. The same study found that owners of pastoral and utility breeds such as collies and corgis were the most extroverted.

    Likewise, a study published in May in the journal Anthrozoos found that people with more argumentative personalities are more likely to choose bull terriers or other breeds with a reputation for aggression than more agreeable types.

    Aggressive owners, aggressive breeds
    Wells and her colleague Peter Hepper, also of Queen's University Belfast, recruited 147 dog owners from obedience classes in Northern Ireland and asked them to fill out a personality questionnaire. Only owners of German shepherds, rottweilers, Labrador retrievers and golden retrievers were included in the questionnaire.

    "We deliberately wanted to focus on breeds that are commonly owned, but at opposite ends of the spectrum in terms of public perception of temperament — both German shepherds and rottweilers are commonly perceived to be aggressive, while labs and retrievers (breeds frequently used to advertise organizations such as Guide Dogs for the Blind) are more likely to regarded in a nonaggressive light," Wells said.

    Of the personality traits studied, the only difference between breed types that emerged was in psychoticism, such that owners of stereotypically aggressive breeds were more aggressive themselves than owners of more relaxed dogs.

    The study still leaves open the question of whether aggressive people choose aggressive dog breeds and then intentionally train them to be vicious, Wells said. Other factors beyond personality, such as allergies and size, can also influence dog-breed choice, she added. 

    "Just because someone with a higher psychotic tendency owns a breed that is widely perceived to be aggressive, does not necessarily mean that animal is a threat to society," Wells said.

  • How'd he do that? Olympic sprinter breaks leg, keeps running

    Anja Niedringhaus / AP

    United States' Manteo Mitchell competes in a 4x400-meter relay heat during the athletics in the Olympic Stadium at the 2012 Summer Olympics, in London on Thursday. Manteo had half a lap to go in the first leg of the 4x400-meter relay preliminaries when he broke his leg, and was faced with a choice: keep running or stop and lose the race.

    He heard the break. He felt the pain. And he just wanted to lie down.

    But after he broke his leg during the semifinal round of the men’s Olympic 4 x 400 meter relay on Thursday, sprinter Manteo Mitchell kept on running, even though, he said, “It felt like somebody literally just snapped my leg in half.”

    “It’s impressive both because he’s dealing with pain as well as not having all of his parts in an optimal situation,” says Dr. Balu Natarajan, a sports medicine specialist in Chicago.

    He attributes Mitchell’s feat to a combination of the highly trained athlete’s fight-or-flight response to pain and the fact that the bone he broke in his lower left leg, the fibula, absorbs less shock and does less work than the other leg bones.

    “Part of it was that the fibula contributes less to weight bearing as opposed to the femur and tibia and part of it is that in that high-energy situation, he has enough adrenaline and endorphins kicking throughout his body that he’s feeling a lot less pain at that moment,” said Natarajan, who also serves on the medical team of the Chicago Marathon.

    Had the 25-year-old Mitchell broken his femur or tibia, it would have been nearly impossible for him to finish the race, he said. If a leg bone had to break, he was in a sense lucky it was the fibula.

    “If it’s a short enough distance and a high level enough athlete, even with a broken fibula, someone can finish the race,” Natarajan said.

    In a statement released through USA Track & Field, Mitchell said the roar of the crowd was so loud that nobody heard his “little war cry,” and he said he didn’t want to let his teammates down. Mitchell finished his heat in 46.1 seconds, only 1.5 seconds longer than the runner of the next leg; the U.S. qualified for the finals and finished in the fastest time ever run in the first round of the relay at the Olympics. On Friday, the U.S. team went on to win a silver medal, thanks in part to Mitchell's sacrifice.

    In a high-stakes event like the Olympics after years of training, athletes sometimes will stop at nothing, experts say.

    “There’s so much that’s tied into the psyche during a race like this, it really can override a lot of things we would feel outside of such a high energy situation,” Natarajan said. “If the same thing happened on training run and no one was around, he would very likely have stopped.”

    “Anybody who has trained for a particular event for four years, really they have one goal, and between that and the tremendous conditioning and excellent biomechanics, it’s really the perfect confluence of factors that might allow someone to overcome a break like this,” he said.

    Mitchell said he had slipped on the stairs a few days earlier, but had it checked out, felt fine and didn't think much of it. Mitchell’s strong finish in the race was a clear example of a top athlete’s ability to put mind over matter, says Frank Smoll, a professor of sport psychology at the University of Washington.

    “It’s a very good illustration of how highly motivated they are and their willingness to pursue and persist and play through pain, so that the importance of what they’re doing really outweighs the potential negative consequences, in this case, physical harm,” he said.

    “They’re highly dedicated athletes, they’re courageous, and they’re willing to, at their own self-sacrifice, give it their all,” Smoll said.

    The training Olympic athletes receive in "attention control," the ability to block out distractions like pain, helps them succeed, Smoll said, adding: “It’s not just the physical ability that makes the elite athletes but the mental preparation is what makes them excel.”

    The U.S. men's 4 x 400 relay team won a silver medal on Friday; Mitchell, who has been fitted with a boot and crutches, will receive a medal with the rest of the team.

  • We may be hardwired to go with our first instinct

    Say you’re at a restaurant and you quickly pick an entrée. You might believe you based your choice on your taste buds, but there is a good chance that you selected that option because it was first on the menu.

    It probably comes as little surprise—being first is best.

    Researchers found that when people need to make a quick decision, they choose the first item. And they believe that is the correct choice.

    “There is a lot of evidence to suggest that firsts have a privileged status,” says Dana R. Carney, assistant professor at University of California, Berkley’s Haas School of Business.

    “First arguments are more persuasive … first exerts a type of power in preference and choice.”

    Carney and co-author Mahzarin R. Banaji—professor of psychology at Harvard University—conducted a series of experiments where they asked subjects to make decisions quickly. In each situation, participants selected the first option.

    In one experiment, 123 participants picked their favorite out of three groups: two teams; two male salespeople; and two female salespeople. First, the researchers asked participants if they wished to join the Hadley or Rodson teams. Next, the researchers told the subjects they were purchasing a car and introduced them to salesmen, Jim and Jon. The subjects immediately had to select the salesman they preferred. Then the participants learned they had to remake their car purchase decision and met Lisa and Lori. Again, they ranked the saleswomen.  

    The subjects self-reported their preference by saying I prefer Lisa or Lori and also participated in a time-reaction test, forcing them to automatically and unconsciously choose a favorite. In both the conscious and unconscious exercises, subjects preferred the first person or team they encountered.

    In another trial, the researchers asked 207 people at a train station to quickly select a piece of gum; again people selected the piece presented to them first.

    “What we’re talking about is general human—even animal—predisposition to prefer firsts, when the ability to think is taken away,” explains Carney.

    She adds a caveat. When people are better informed or have more time to consider a decision they don’t always to select the first. Selecting the primary option helps people as they make quick decisions, which people do to avoid being indecisive.  

    “A state of indecision is uncomfortable … having too many choices is called choice overload. You are searching for something to hang your hat on,” she says, and the first option is the easiest pick.

    Also, Carney and Banaji wondered if people still select the first if the choice is between negatives. They asked 31 participants to examine the mug shots of two 29-year-old criminals, who committed the same offenses, and determine who deserved parole and who deserved freedom. Again, people believed the first criminal they saw should be paroled while the second should remain in prison. 

    “We argue in the paper that we think it is a hardwired [biological] mechanism to prefer the first.”  

    The paper “First is Best” appears in the online journal PLoS ONE

  • You've just won a gold medal! So why are you trying to eat it?

    Emmanuel Dunand / AFP - Getty Images

    Mmm, gold medal ... om nom nom. Team USA chomp on their medals after winning the women's team gymnastics final on July 31. From left to right, we have Mckayla Maroney, Kyla Ross, Alexandra Raisman, Gabrielle Douglas and Jordyn Wieber.

    After medal-winning Olympians stand on the platform, receive their medals, and solemnly listen to the gold medal winner’s national anthem, they leave the stage and face an army of photographers. In front of the flashing lights, many winners grab their medals and take a bite.

    It takes years of grueling training and competition to nab gold at the Olympics. So why do the winners immediately chomp on their hard-earned prizes?

    The simple answer: Because the photographers ask them to, says David Wallechinsky, president of the International Society of Olympic Historians and author of “The Complete Book of the Olympics, via email.

    Related photos: Olympians biting their medals

    While Olympic historians aren’t sure which athlete started the trend, they believe the athletes nibble their prizes to test the metal. People once bit gold coins try to make an indent; a small tooth mark in a coin assured it consisted of real gold, which is more malleable than counterfeit gold-plated lead coins. 

    “We know that only in 1912 the gold medals were real gold and that in all later Olympics the gold medals were made from silver with a gilt layer to show it as being gold,” explains Tony Bijkerk, secretary-general of the International Society of Olympic Historians via email. The 2012 medals contain 1.34 percent of gold, making it one of the biggest medals.

    Um, how do we break this to you, Team USA? You didn't actually win gold

    “Unfortunately, the gold layer sometimes had a tendency to fade over the years. Fanny Blankers-Koen, the heroine of the 1948 Olympics in London, who was a good friend of mine, once told me that she had to have her four gold medals re-gilded two times over the years.” (Blankers-Koen was a 30-year-old mother of two who medaled in running events, helping to prove women could be as athletic as men.)

    Even though the medal isn’t solid gold, Bijkerk suspects that Olympians could make a mark in the medal, depending on how hard they bite. And some really sink their teeth into their prizes. At the 2010 Winter Olympics, German luger, David Moeller, who won a silver medal, broke his tooth while mugging for cameras and showing off his bite.

    Psychologist Frank Farley believes that medalists bite their medals because, at this point, it’s what winning Olympians do.

    “Sports all have their eccentricities,” says Farley, a professor from Temple University in Philadelphia and former president of the American Psychological Association. “If you want to be part of the winning zeitgeist, that winning culture, you participate in that winning practice.”

    But he believes that medal biting is more than Olympians simply acting like winners. “It makes your medals yours,” Farley says. “It’s an emotional connection with your accomplishment.”

    And even if the Olympians do indent their medals, it makes the prize individual; bite imprints are as unique as the swirls on our digits.

    “The concept of the icon, something representing something else, is pretty deep in all of us. In the Olympics, they have a twist on it; it’s like imprinting [yourself] there for all of time.”
