'Fast' in Fast Food Takes Over Your Life

Short attention spans even affect leisure activities: researchers

(Newser) - Americans’ exposure to the “instant gratification” of fast food makes them more impatient for fulfillment in other aspects of life, even the low-key pleasure of an afternoon stroll. Research subjects exposed to fast food logos complete tasks more quickly than a control group, even if there is no time... More »

Higher SATs Mean More Cash for Egg Donors

Some worry about commodification as prices approach $35K

(Newser) - Smarter women—or at least those who test well—get paid more to donate eggs. "Holding all else equal, an increase of 100 SAT points in the score of a typical incoming student increased the compensation offered to oocyte donors at that college or university by $2,350,"... More »

Shot to Brain Could Calm Fears

At least it does in goldfish in Japanese study

(Newser) - A study on goldfish has yielded hope for a temporary fix for humans paralyzed by fear, Japanese scientists say. They injected anesthetic directly into the fishes’ brains—which are similar to many mammals’—and thus switched off its fear center. The news could mean temporary calm for those afraid... More »

Corn Syrup Makes You Fatter Than Sugar

Princeton researchers say rat study answers contentious question

(Newser) - It may not end the debate, but researchers say they have definitively proven that high-fructose corn syrup is many times more likely to contribute to obesity than sugar. The Princeton team gave one group of rats water spiked with sugar, and another water with corn syrup. Though the sugar water... More »

Scientists Think Injection Could 'Cure' Fear

Maybe some lidocaine in the cerebellum can erase phobias

(Newser) - A team of Japanese researchers say they’ve found evidence that a simple injection could turn off the brain’s ability to become afraid, or even reprogram it to eliminate certain phobias. The scientists say that since fear is a learned reaction, they should be able to find the part... More »

Aggressive Treatment Doesn't Help Diabetics

Findings reverse current thinking, may cut costs

(Newser) - Rigorous treatment to lower blood pressure or cholesterol below current guidelines does not benefit—and may actually hurt—diabetics, a new study shows. The findings, published online in the New England Journal of Medicine, suggest doctors may have to find new ways to treat diabetic patients. But that's not entirely... More »

Pregnant Women Also Watch TV for 2

Fetuses rejoice when mom watches happy movie, go quiet for sad ones

(Newser) - Unborn children are so in tune with their mothers that they get bad vibes when mom watches a sad movie, and are perked up by an uplifting flick. That’s the conclusion of Japanese researchers, who plopped one group of expectant mothers in front of The Sound of Music, and... More »

Genome Breakthrough Zeroes In on Disease

New approach decodes entire genomes of individual patients

(Newser) - Two teams of researchers have identified the exact genetic cause of their patients' rare diseases by sequencing their entire genomes, a sharp but promising departure of the previous application of genetics to disease. “I suspect that in the next few years human genetics will finally begin to systematically deliver...

Stressed Men Go for Novelty in Sex Partners

Men suddenly choose women who don't look like them

(Newser) - Men who are under stress choose different women as sex partners than they do under normal circumstances, a new study shows. Men tend to be attracted to women whose facial features are like their own, but if stress is added to the equation, they flip to females who don’t... More »

Vitamin D Found to Boost Immunity

New study discovers that 'sunshine vitamin' activates T-cells

(Newser) - Taking in some sunshine is vital for your immune system, according to a new study released yesterday. A group of Danish researchers have discovered that infection-killing T cells rely on vitamin D to activate, Reuters explains. “If the T cells cannot find enough vitamin D in the blood, they...

PSAs Drive Bingers to Drink More: Study

Drinkers already feel guilty; ads make them feel worse

(Newser) - The shaming quality of public-service announcements aimed at curbing binge drinking actually pushes such drinkers to imbibe more. And, a study finds, the spots are often so guilt-inducing that they can push someone feeling bad about some other malfeasance—cheating, say—to drink. One of the researchers suggests a different...

Heart Risk Linked to Obesity—in Preschoolers

Definitive connection can't be made due to lack of relevant study

(Newser) - Levels of a marker tied to adult heart disease were twice as high in the blood of obese children as in the blood of average-weight kids in a recent study. The twist is that the research subjects were 3 to 5 years old, sparking concerns about the cumulative health effects... More »

Half of 6-Year-Old Brit Girls Wish They Were Skinnier

In study, 50% would like to be 3 sizes skinnier for popularity

(Newser) - Half of the 6-year-old girls in Britain would like to be a lot skinnier than they are. That’s the conclusion of a Cambridge study that asked the pint-size participants to choose an ideal body from digitally altered photographs of themselves. Fifty percent went with the skinniest image, which was... More »

Researchers Find Cancer 'Fingerprints'

Rearranged chromosomes can be used to ID tumors, personalize treatment

(Newser) - Scientists have developed a new, more accurate method of tracking specific cancers using genetic “fingerprints”— the unique way every cancer rearranges chromosomes. Those rearrangements can be pinpointed with new genetic sequencing methods, allowing doctors to follow the cancer’s trail in the blood. The breakthrough is a key... More »

Study: Driving's Really Bad for Your Conversation Skills

It's harder to remember details when you're occupied

(Newser) - Verifying that what most think is obvious is indeed true, scientists say driving really kills your conversation and memory skills. A study found that those talking and driving were much worse at relaying details of the conversation, and at remembering details later. No harder than walking and chewing gum? Ha!... More »

When Shoveling Increases, So Do Heart Attacks

Studies show exertion-related cardiac deaths surge during storms

(Newser) - Take it easy, snow shoveler—your activity causes heart attacks. Well, not exactly, Slate reports, but 2 studies show a strong correlation between heavy snowfall and an increase in heart attack deaths. In one, deaths went up 22% in the week of Northeastern blizzards and remained up in the next... More »

Botox Numbs Emotional Response

If you can't frown, brain finds it harder to be sad, study surmises

(Newser) - If you turn your frown upside down with Botox, your brain gets the message and makes you less receptive to negative emotional stimuli. That’s the conclusion of a new study of people who had their frown muscles paralyzed with the cosmetic toxin. Researchers tested subjects on the speed of... More »

Fearless Gambler? Could Be Brain Damage

Harm to amygdala seems to impair 'loss aversion'

(Newser) - People with damage to their amygdala, a deep part of the brain that governs basic value judgments, are more likely than others to take big risks for uncertain payoffs. A new study pitted 2 women with amygdala-specific lesions against 6 controls in tests of their willingness to gamble. The control... More »

Being Terrific Uncles Helps Gays Keep Genes Going

Nieces, nephews then more likely to keep bloodline going

(Newser) - Gay men’s tendency to lavish love and attention on their nieces and nephews could be a key to keeping a “gay gene” alive, a study shows. Looking at male homosexuals in Samoa—where they’re considered their own gender, and therefore fully integrated into family life—scientists saw... More »

Turns Out Abstinence Ed Does Cut Teen Sex

It beat safe sex program in recent study

(Newser) - Abstinence-only sex education is back on solid scientific ground, with a study showing the method may be more effective than safe sex education in discouraging young teens from taking the plunge. Different groups of 6th- and 7th-graders were given short courses in abstinence, safe sex, or a combination of the... More »
