Common anthrax sampling methods need improvement
A research team from the National Nuclear Security Administration's Sandia National Laboratories has discovered that common anthrax sampling methods need improvement. The research shows that more deadly spores remain after decontamination than previously believed.
Color perception is not in the eye of the beholder: it's in the brain
First-ever images of living human retinas have yielded a surprise about how we perceive our world. Researchers at the University of Rochester have found that the number of color-sensitive cones in the human retina differs dramatically among people—by up to 40 times—yet people appear to perceive colors the same way.
Changes in brain, not age, determine one's ability to focus on task
When it comes to focusing on a task amid distractions, some folks more than 60 years old are as mentally sharp as 22-year-olds. Others struggle. Researchers at the Beckman Institute for Advanced Science and Technology at the University of Illinois at Urbana-Champaign have shed some light on why that is.
Schizophrenia: delusion without illusion
Scientists have discovered that schizophrenia sufferers are not fooled by a visual illusion and are able to judge it more accurately than non-schizophrenic observers.
New imaging technique reveals how likely you are to break a bone
Scientists have developed a technique which can be used to reveal the strength of bones, allowing doctors to more accurately estimate the risk of bone fracture.
The stomach offers greater lie detection accuracy
A new study suggests that changes in gastric physiology perform better than standard polygraph methods in distinguishing between lying and telling the truth. The University of Texas study, released at the 70th Annual Scientific Meeting of the American College of Gastroenterology, demonstrates a clear link between the act of lying and a significant increase in gastric arrhythmia.
WA team uses baby tooth to solve death mystery
A team of Perth scientists have used a keepsake baby tooth to help a Queensland couple solve the mystery of their 7-year-old daughter's death - 14 years after she died.
Travelers can avoid jet lag by resetting their body clocks
A simple, at-home treatment -- a single light box and the over-the-counter drug melatonin -- allows travelers to avoid jet lag by resetting their circadian body clock before crossing several time zones, according to new research being published in The Endocrine Society's Journal of Clinical Endocrinology and Metabolism.
UV measurement tool aids defense against microbes in tap water
Researchers at Duke's Pratt School of Engineering have developed a new way to measure microbes' exposure to ultraviolet light. The tool could bolster efforts to use UV light to improve the quality and safety of tap water in the U.S.
Success tastes sweet for scientists
A low-calorie sweetener that tastes like sugar and could help control diseases like diabetes and obesity may be closer to reality thanks to research published recently.

Common viruses may cause cancer
In some cases, the fusion of human cells is a normal process that leads, for instance, to the formation of muscle and bone. Viral infections can also cause cell fusion, but cells fused by viruses are widely considered to be harmless because they are generally believed to die without consequences for the host. According to a recent study, however, cell fusion triggered by viruses is a possible contributing factor in the development of human cancer.
Omega-3 fats save life of a terminal cancer patient
Ron Pardini is not a medical doctor. Yet he is seen as a hero by his cancer-stricken neighbor, "D.H." Pardini helped the 78-year-old after D.H. was diagnosed with terminal lung cancer.
Big portions influence overeating as much as taste
Large portions push people to overeat -- even to overeat foods they don't like.
Meditation associated with increased grey matter in the brain
Meditation is known to alter resting brain patterns, suggesting long lasting brain changes, but a new study by researchers from Yale, Harvard, Massachusetts General Hospital, and the Massachusetts Institute of Technology shows meditation also is associated with increased cortical thickness.
Exercise adds years to life and improves quality
Exercise is a lot like spinach … everybody knows it's good for you; yet many people still avoid it, forgoing its potential health benefits.
Finding the mind's eye
Dartmouth professor of psychological and brain sciences Peter Tse has published new results in his on-going investigation of the brain and how it transforms visual stimuli into conscious experience.
"Sharp" older brains are not the same as younger brains
Researchers working with rats have found the first solid evidence that still "sharp" older brains store and encode memories differently than younger brains.
Genes contribute to patriotism and group loyalty
Research showing how genes affect group loyalty and patriotism was published in the October 2005 issue of Nations and Nationalism, an academic journal of the London School of Economics.
Womb needed for proper brain development
The brains of babies born very prematurely do not develop as well as those who are carried to full-term, according to new research presented today at the annual meeting of the Society for Neuroscience in Washington, D.C.
Early experience may shape our sensory perceptions
Our brain's ability to combine sensory information from a single event – such as seeing an ambulance and hearing its siren – has been shown to speed our reactions, help us identify objects and heighten our awareness. New research in animals suggests that it's unlikely that we're born with this ability. Instead, its development may depend on our sensory experiences during the early months of life.
