How does the brain tell time?
"Time" is the most popular noun in the English language, yet how would we tell time if we didn't have access to the plethora of watches, clocks and cell phones at our disposal?
Chemicals in brown algae may protect against skin cancer
Substances extracted from a marine seaweed may protect against skin cancer caused by too much sun, new research suggests.
How does your brain respond when you think about gambling or taking risks?
Should you leave your comfortable job for one that pays better but is less secure? Should you have a surgery that is likely to extend your life but poses some risk that you will not survive the operation? Should you invest in a risky startup company whose stock may soar even though you could lose your entire investment? In the Jan. 26 issue of the journal Science, UCLA psychologists present the first neuroscience research comparing how our brains evaluate the possibility of gaining versus losing when making risky decisions.
Scientists find new genetic clue to cause of alzheimer's disease
Variations in a gene known as SORL1 may be a factor in the development of late onset Alzheimer's disease, an international team of researchers has discovered. The genetic clue, which could lead to a better understanding of one cause of Alzheimer's, is reported in Nature Genetics online, Jan. 14, 2007, and was supported in part by the National Institutes of Health (NIH).
Microwave oven can sterilize sponges, scrub pads
Microwave ovens may be good for more than just zapping the leftovers; they may also help protect your family.
Action video games sharpen vision 20 percent
Video games that contain high levels of action, such as Unreal Tournament, can actually improve your vision.
Prehistoric origins of stomach ulcers uncovered
An international team of scientists has discovered that the ubiquitous bacteria that cause most painful stomach ulcers have been present in the human digestive system since modern man migrated from Africa over 60,000 years ago. The research, published online by the journal Nature, not only furthers our understanding of a disease causing bacteria but also offers a new way to study the migration and diversification of early humans.
Decision-making: demonstration of a link between cognition and execution
For the first time, a team of researchers in the Movement, Adaptation, Cognition Laboratory (CNRS/University Victor Ségalen, Bordeaux) has revealed the existence of an interaction at the cellular level between cognitive information and motor information.
Scientists see dna get sunburned for the first time
For the first time, scientists have observed DNA being damaged by ultraviolet (UV) light.
Horse genome assembled
The first draft of the horse genome sequence has been deposited in public databases and is freely available for use by biomedical and veterinary researchers around the globe, leaders of the international Horse Genome Sequencing Project announced.

Silicon medicines may be effective in humans
As carbon-based life forms, humans and other animals, invariably, are treated for disease with the help of carbon-based medicines. But now, in a promising new study, scientists have shown that silicon — the stuff of computer chips, glass and pottery — may have extraordinary therapeutic value for treating human disease.
More than meets the tongue
Does orange juice taste sweeter if it's a brighter orange? A new study in the March issue of the Journal of Consumer Research finds that the color of a drink can influence how we think it tastes. In fact, the researchers found that color was more of an influence on how taste was perceived than quality or price information.
A clever catchphrase goes a long way -- even if you don't get the joke
A new study in the Journal of Consumer Research discusses the benefits of slogans with multiple meanings, like a cell phone company using the slogan, "The Clear Alternative" or a tax-preparation service advertising that "You Get More in Return." The researchers found that some people are better at recognizing additional meanings than others, but they also found that degree of understanding has little impact on how well people respond to the catchphrases. In fact, consumers who didn't get the joke often expressed the greatest appreciation of the punned slogans.
Numbers are just numbers, but how you grasp them fills in details
Quickly now, which is a higher risk that you will get a disease: 1 in 100; 1 in 1,000; or 1 in 10? Choosing the correct answer depends on a person's numeracy – the ability to grasp and use math and probability concepts, according to a presentation at the annual meeting of the American Association for the Advancement of Science.
Revealing secret intentions in the brain
Every day we plan numerous actions, such as to return a book to a friend or to make an appointment. How and where the brain stores these intentions has been revealed by John-Dylan Haynes from the Max Planck Institute for Human Cognitive and Brain Sciences, in cooperation with researchers from London and Tokyo.
Psychologist says neurochemical processes explain romantic attraction
The Beatles' George Harrison wondered in his famous love song about the "something" that "attracts me like no other lover." A University at Buffalo expert explains that that "something" is actually several physical elements that -- if they occur in a certain order, at the right time and in the right place -- can result in true love.
New research finds people and pigeons see eye to eye
Pigeons and humans use similar visual cues to identify objects, a finding that could have promising implications in the development of novel technologies, according to new research conducted by a University of New Hampshire professor.
Liposuctioned fat stem cells to repair bodies
Expanding waistlines, unsightly bulges: people will gladly remove excess body fat to improve their looks. But unwanted fat also contains stem cells with the potential to repair defects and heal injuries in the body.
Googling brain proteins with 3-d goggles
The Allen Brain Atlas, a genome-wide map of the mouse brain on the Internet, has been hailed as "Google of the brain." The atlas now has a companion of the brain's working molecules, a sort of pop-up book of the proteins, or proteome map, that those genes express.
Picower study points to a genetic link for schizophrenia
Gene mutations governing a key brain enzyme make people susceptible to schizophrenia and may be targeted in future treatments for the psychiatric illness, according to MIT and Japanese researchers.
