Addictive behavior is determined by conscious, rapid thought processes, not necessarily by the content of visual stimuli as previously thought.

New research suggests that smoking increases the production of osteopontin in the lungs, which contributes to the development of smoking-related lung disease.
Despite the common perception that total hip replacements last about 10 years, researchers have found that the devices are extremely durable, even 20 years after surgery.
Physicists have harnessed the phenomenon, "spooky action at a distance," to shed light on another unusual and previously difficult aspect of quantum physics -- that of distinguishing between two similar quantum devices.
Scientists have developed an entirely new approach to imaging that does not require a CCD or CMOS camera. Building on more than a decade of research on photonic time stretch, a technique for capturing illusive events, the team has demonstrated a continuous running camera that captures images at 6 million frames per second, roughly a thousand times faster than conventional...
A unique mother-daughter study that used magnetic resonance to measure breast density in younger women shows that one's percent of breast water could be linked to the risk of breast cancer in middle age and older.
Compact lasers which can work in formerly inaccessible parts of the spectrum and are suitable for mass production are now within reach.
Having strong memories of that rich, delicious dessert you ate last night? If so, you shouldn't feel like a glutton. It's only natural. This study points to new approaches for treating obesity and eating disorders.
NASA's MESSENGER spacecraft served up another curveball after a second flyby of the hot inner planet Oct. 6 detected magnesium -- an element created inside exploding stars and which is found in many medicine cabinets on Earth -- clumped in the tenuous atmosphere of the...
Flu vaccine delivered through skin patches containing microneedles has proven just as effective at preventing influenza in mice as intramuscular, hypodermic flu immunization. A team of researchers believes the new microneedle skin patch method of delivering flu vaccine could improve overall seasonal vaccination coverage in people because of decreased pain, increased convenience, lower cost and...
A new study documents for the first time the process in which increased mercury emissions from human sources across the globe, and in particular from Asia, make their way into the North Pacific Ocean and as a result contaminate tuna and other seafood. Because much of the mercury that enters the North Pacific comes from the atmosphere, scientists have predicted an additional 50 percent increase in...
A defining hallmark of Alzheimer's disease is the accumulation of the amyloid-beta protein, otherwise known as "senile plaques," in the brain's cortex and hippocampus, where memory consolidation occurs. Researchers have identified a novel protein which, when over-expressed, leads to a dramatic increase in the generation of the amyloid-beta...
Scientists testing a cosmetic anti-aging product sold commercially have shown it can clinically reduce wrinkles and improve the appearance of skin damaged by everyday exposure to sunlight.
Astronomers have found hundreds of extrasolar planets in the last two decades, and new research indicates they might have found even more except for one thing -- some planets have fallen into their stars and simply no longer exist.

Constantly "re-rolling the dice", combining and selecting: "Evolutionary algorithms" mimic natural evolution in silico and lead to innovative solutions for complex problems.
If a little-known microbe called Arcobacter butzleri has contaminated the water you drink or the food you eat, this troublesome pathogen could make you sick. Symptoms include diarrhea, stomach cramps, nausea, vomiting and fever, all of which can become chronic if left...
A pest with a voracious appetite may have met its match in a predatory mite being evaluated as a biocontrol agent.
White-nose syndrome, a wildlife crisis of unprecedented proportions, has killed hundreds of thousands of bats from Vermont to West Virginia and continues unchecked. Now, the U.S. Fish and Wildlife Service is asking those who use caves where bats hibernate - called hibernacula - to take extra precautions and to curtail activities to help prevent the spread of...
If carbon dioxide emissions are halved by 2050 compared to 1990, global warming can be stabilized below two degrees.
New data from several studies are useful in evaluating new techniques for early diagnosis and treatment of lung cancer.
Cod bycatch was at least 70 per cent higher than target levels on the southern Grand Banks near Canada, holding back recovery of one of the world's best known fisheries following its spectacular collapse and closure in the early 1990s.
Dairy cows that produce USDA-certified organic milk also produce manure that may gradually replenish soil nutrients and potentially reduce the flow of agricultural pollutants to nearby water sources, according to new findings.
Manufacturers are now required to state on food labels the amount of trans fatty acids, also called hydrogenated fats, in packaged foods. Both trans fatty acids and saturated fatty acids are associated with elevated heart disease risk factors.
The U.S. National Arboretum is "going green" with the installation of its first solar-powered drip irrigation system that will save electricity and water at the 446-acre facility operated by the Agricultural Research Service in Washington, DC.
What happened in the first trillionth of a trillionth of a trillionth of a second after the Big Bang? Super-sensitive microwave detectors may soon help scientists find out.
