Monkeys don't go for easy pickings
Animals' natural foraging decisions give an insight into their cognitive abilities, and primates do not automatically choose the easy option. Instead, they appear to decide where to feed based on the quality of the resources available and the effect on their social group, rather than simply selecting the nearest food available.
Brain region central to placebo effect identified
Researchers have pinpointed a brain region central to the machinery of the placebo effect—the often controversial phenomenon in which a person's belief in the efficacy of a treatment such as a painkilling drug influences its effect.
Children's ability to describe past event develops over time
In the first study to examine how children talk about the time-related features of their experiences--when, how often, in what order events occur--researchers have found intriguing changes as children grow older. The study's findings may have implications for understanding these aspects of cognitive development as well as for questioning child witnesses and victims.
Mit ids mechanism behind fear
Researchers from MIT's Picower Institute for Learning and Memory have uncovered a molecular mechanism that governs the formation of fears stemming from traumatic events.
Researchers show that culture influences brain cells
A thumbs-up signifies "I'm good." The rubbing of one pointed forefinger against the other means "shame on you." The infamous middle-finger salute — well, you know. Gestures that convey meaning without speech are used and recognized by nearly everyone in our society, but to someone from a foreign country, they may be incomprehensible.
More muscle for the argument to give up smoking
Researchers at The University of Nottingham have got more bad news for smokers. Not only does it cause cancer, heart attacks and strokes but smokers will also lose more muscle mass in old age than a non-smoker. The effect of this predisposes smokers to an accelerated decline in physical function and loss of independence.
New study sheds light on how we would have done things differently
If you're like most people, you've probably experienced a shoulda-woulda-coulda moment; a time when we lament our missteps, saying that we should have invested in a certain stock, should have become a doctor instead of a lawyer and so on.
Exercise, rest, repeat: how a break can help your workout
Taking a break in the middle of your workout may metabolize more fat than exercising without stopping, according to a recent study in Japan. Researchers conducted the first known study to compare these two exercise methods—exercising continually in one long bout versus breaking up the same workout with a rest period. The findings could change the way we approach exercise. Who wouldn't want to take a breather for that?
Ability to listen to two things at once is largely inheritedPrivacy protection software utilities
Your ability to listen to a phone message in one ear while a friend is talking into your other ear — and comprehend what both are saying — is an important communication skill that's heavily influenced by your genes, say researchers of the National Institute on Deafness and Other Communication Disorders (NIDCD), one of the National Institutes of Health.Did you know that all your internet history can be reviewed by anyone with access to simple free tool available online.

Born to lose: how birth weight affects adult health and successPrivacy protection software utilities
Birth weight has significant and lasting effects, a new study finds. Weighing less than 5.5 pounds at birth increases the probability of dropping out of high school by one-third, reduces yearly earnings by about 15 percent and burdens people in their 30s and 40s with the health of someone who is 12 years older.Did you know that all your internet history can be reviewed by anyone with access to simple free tool available online.

The future of medicine: insert chip, cure disease?
Imagine a chip, strategically placed in the brain, that could prevent epileptic seizures or allow someone who has lost a limb to control an artificial arm just by thinking about it.
Faster-acting antidepressants closer to becoming a reality
A new study has revealed more about how the medication ketamine, when used experimentally for depression, relieves symptoms of the disorder in hours instead of the weeks or months it takes for current antidepressants to work.
Ucla study links air pollution to clogged arteries
Got high cholesterol? You might want to stay away from air pollution.
Obesity is socially contagious, study finds
Are your friends making you fat? Or keeping you slender? According to new research from Harvard and the University of California, San Diego, the short answer on both counts is "yes."
Scratch no more: gene for itch sensation discovered
Itching for a better anti-itch remedy? Your wish may soon be granted now that scientists at Washington University School of Medicine in St. Louis have identified the first gene for the itch sensation in the central nervous system. The discovery could rapidly lead to new treatments directly targeting itchiness and providing relief for chronic and severe itching.
Fruit fly gene from 'out of nowhere' may change ideas about how new genes are formed
Scientists thought that most new genes were formed from existing genes, but Cornell researchers have discovered a gene in some fruit flies that appears to be unrelated to other genes in any known genome.
One species, many genomes
Faster growth, darker leaves, a different way of branching - wild varieties of the plant Arabidopsis thaliana are often substantially different from the laboratory strain of this small mustard plant, a favorite of many plant biologists. Which detailed differences distinguish the genomes of strains from the polar circle or the subtropics, from America, Africa or Asia has been investigated for the first time by research teams from Tübingen, Germany, and California led by Detlef Weigel from the Max Planck Institute for Developmental Biology. The results were surprising: The extent of the genetic differences far exceeds the expectations for such a streamlined genome, as the scientists write in Science magazine.
More fish oil, less vegetable oil, better for your health
Scientists have provided new evidence that using more fish oil than vegetable oil in the diet decreases the formation of chemicals called prostanoids, which, when produced in excess, increase inflammation in various tissues and organs.
How to manipulate perceptual focus in advertisements
In a new study from the August issue of the Journal of Consumer Research, researchers from Northwestern University demonstrate how advertisements can be manipulated to cause overemphasis of a particular feature and increase the likelihood that a certain product is chosen. Their finding runs contrary to economic models, which assume that choices are based on stable preferences and should not be influenced by the inclusion of inferior options.
