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.
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.
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.
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.
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.
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.
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.
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.
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.
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.

Decoding the dictionary: study suggests lexicon evolved to fit in the brain
The latest edition of the Oxford English Dictionary boasts 22,000 pages of definitions. While that may seem far from succinct, new research suggests the reference manual is meticulously organized to be as concise as possible — a format that mirrors the way our brains make sense of and categorize the countless words in our vast vocabulary.
Young children rely on one sense or another, not a combination
Unlike adults, children younger than eight can't integrate different forms of sensory input to improve the accuracy with which they perceive the world around them, according to a pair of studies reported online in Current Biology, a publication of Cell Press, on May 1st.
New research shows sleight of hand is not so slight
Typing on a keyboard or scribbling on paper may be similar activities, but there is a significant difference in how the body moves, according to new motor development research.
Brookhaven scientists explore brain's reaction to potent hallucinogen
Brain-imaging studies performed in animals at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory provide researchers with clues about why an increasingly popular recreational drug that causes hallucinations and motor-function impairment in humans is abused. Using trace amounts of Salvia divinorum - also known as "salvia," a Mexican mint plant that can be smoked in the form of dried leaves or serum - Brookhaven scientists found that the drug's behavior in the brains of primates mimics the extremely fast and brief "high" observed in humans.
Design of wine bottles makes significant difference in perception, taste
Whether you want a wine to convey sophistication, ruggedness or even how much it costs, it has a lot to do with the way that wine is packaged and designed.
Cause and affect: emotions can be unconsciously and subliminally evoked
Most people agree that emotions can be caused by a specific event and that the person experiencing it is aware of the cause, such as a child's excitement at the sound of an ice cream truck. But recent research suggests emotions also can be unconsciously evoked and manipulated.
New research shows consistency in synaesthetic experiences
A quirky psychological phenomenon known as "grapheme-color synaesthesia" describes individuals who experience vivid colors whenever they see, hear, or think of ordinary letters and digits. A hallmark of synaesthesia is that individuals seem to be idiosyncratic in their experiences. That is, most synesthaetes will consistently see the same colors accompanied with specific graphemes, but few of these experiences appear to be shared with other synesthetes.
Secondhand smoke exposure can cause cell damage in 30 minutes
Exposure to secondhand smoke even for a brief period is injurious to health, a new study by researchers at the University of California, San Francisco has found.
Does the brain control muscles or movements?
One of the major scientific questions about the brain is how it can translate the simple intent to perform an action—say, reach for a glass—into the dynamic, coordinated symphony of muscle movements required for that action. The neural instructions for such actions originate in the brain's primary motor cortex, and the puzzle has been whether the neurons in this region encode the details of individual muscle activities or the high-level commands that govern kinetics—the direction and velocity of desired movements.
Superbug genome sequenced
The genome of a newly-emerging superbug, commonly known as Steno, has just been sequenced. The results reveal an organism with a remarkable capacity for drug resistance. The research was carried out by scientists at the Wellcome Trust Sanger Institute near Cambridge and the University of Bristol.

Ive always wanted to be somebody, but I see now I should have been more specific.
