Scientists have found that the compound resveratrol, found in red wine and grape skin, slows age-related deterioration and functional decline of mice on a standard diet, but does not increase longevity when started at middle age. This study is a
Countering a perception that establishing nature reserves in developing nations drives away local communities, a new study finds that human settlements are actually drawn to protected areas in Africa and Latin America. Unfortunately, the researchers also found a link between
A farm irrigation canal would seem a healthier place for toads than a ditch by a supermarket parking lot. But scientists have found the opposite is true. In a study with wide implications for a longstanding debate over whether agricultural
In addition to reducing one's risk for many common diseases, new research found that calorie restriction may slow the aging process. Calorie restriction has long been shown to slow the aging process in rats and mice. Calorie restriction - cutting
Self-organization keeps schools of fish, flocks of birds and colonies of termites in sync. It's also, according to new research, the way cells regulate the final stage of cell division. Scientists have shown that a protein-chemistry-based contour map, which helps
The potential market for tiger products in China is enormous, but a vast majority of the Chinese public would rather have wild tigers than tiger-bone wine, according to new research.
Knowing the preferences of foodborne pathogens such as Escherichia coli O157:H7 is essential to a successful counterattack on these microbes. That's why microbiologists are scrutinizing the little-understood ability of E. coli O157:H7 and Salmonella enterica to contaminate romaine lettuce.
More evidence for the beneficial effect of green tea on risk factors for heart disease has emerged in a new study. The study found that the consumption of green tea rapidly improves the function of (endothelial) cells lining the circulatory
As anyone who has suffered from jetlag knows, we have internal clocks that tell us when to sleep and wake, and we can be miserable when these are disrupted. The daily cycles of many organisms are well known, but what
Scientists have found that a complex, highly conserved and extremely important mechanism of controlling genes is over 150 million years old. The findings have provided new insights into the evolution of genomic or parental imprinting and epigenetic regulation in mammals.
Detecting food-borne diseases such as campylobacter and salmonella long before they enter the food chain would help ensure that the dinner on your table is safe to eat. There is currently no quick and simple way to detect infectious bacteria
Researchers have shown that they can put mouse embryonic stem cells to work building the heart, potentially moving medicine a significant step closer to a new generation of heart disease treatments that use human stem cells. Scientists report in Cell
Many people, scientists among them, are largely unaware of the roles fungi play in the world around us. Research on fungi and fungal diseases are seriously neglected as a result -- a situation with grave negative repercussions for human health,
Thanks to salt and hot chili peppers, researchers have found a calculus-computing center that tells a roundworm to go forward toward dinner or turn to broaden the search. It's a computational mechanism, they say, that is similar to what drives
New research findings provide more evidence that if we get smart about what we eat, our intelligence can improve. According to scientists, dietary nutrients found in a wide range of foods from infant formula to eggs increase brain synapses and
