Study captures brains activity processing speech
You might be able to hear the difference, but to many children and adults, these words sound exactly the same. The problem isn't that they can't hear the sounds. The problem is that they can't tell them apart.
Environment influences when drinking begins; genes' role increases in transition to alcohol dependence
The influence of genetics increases as young women transition from taking their first drink to becoming alcoholics. A team of researchers at Washington University School of Medicine in St. Louis found that although environment is most influential in determining when girls begin to drink, genes play a larger role if they advance to problem drinking and alcohol dependence.
Researchers identify new class of photoreceptors in retina, pointing to new ways sights-and smells-are regulated
The identification of a new class of photoreceptors in the retina of fruit flies sheds light on the regulation of the pigments of the eye that confer color vision, researchers at New York University's Center for Developmental Genetics report in a new study appearing in the Public Library of Science's journal, PloS Biology.
Causes of disease can be revealed by metabolic fingerprinting
Your metabolic 'fingerprint' can reveal much about the possible causes of major diseases, according to the first 'metabolome-wide' association study ever carried out, published in the journal Nature.
Each finger can be moved separately
It can hold a credit card, use a keyboard with the index finger, and lift a bag weighing up to 20 kg – the world's first commercially available prosthetic hand that can move each finger separately and has an astounding range of grip configurations.

Coke or pepsi? Being distracted can make you more susceptible to ads
A can of Coke next to the word "awesome"; a can of Pepsi next to a picture of a happy couple. Seem too basic to be effective advertising? Prior research has shown that reported attitudes towards brands are not affected by such simple juxtapositions. However, a new paper in the June 2008 issue of the Journal of Consumer Research examines our implicit opinions – and finds that we may actually be more susceptible than we think.
Just like penguins and other primates, people trade sex for resources
Female penguins mate with males who bring them pebbles to build egg nests. Hummingbirds mate to gain access to the most productive flowers guarded by larger males.
Saliva can help diagnose heart attack, study shows
Early diagnosis of a heart attack may now be possible using only a few drops of saliva and a new nano-bio-chip, a multi-institutional team led by researchers at The University of Texas at Austin reported at a recent meeting of the American Association of Dental Research.
Unconscious decisions in the brain
Already several seconds before we consciously make a decision its outcome can be predicted from unconscious activity in the brain. This is shown in a study by scientists from the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig, in collaboration with the Charité University Hospital and the Bernstein Center for Computational Neuroscience in Berlin.
Would you steal a buck? How about a can of soda?
It's been a long road from being engulfed in flames in an explosion in Israel to leaving dollar bills in dorm refrigerators at MIT. But in an odd way, it's all connected.
