A growth factor used to rescue dying brain cells may cause unwanted weight loss if placed in specific brain regions — a cautionary warning for experimental treatments to treat Parkinson’s disease that use GDNF, short for glial cell-line derived neurotrophic factor. In addition, the finding broadens understanding of the brain’s role in the regulation of [...]

A typical Western diet, rich in meat and fats and low in complex carbohydrates, is a recipe for colon cancer, scientists say. Researchers have described an expanding body of evidence to show that the composition of the diet directly influences the diversity of the microbes in the gut, providing the link between diet, colonic disease [...]
Researchers have unveiled the evolutionary origin of the different chromosomal architectures found in three species of Agrobacterium. A comprehensive comparison of the Agrobacterium sequence information with the genome sequences of other bacteria suggests a general model for how second chromosomes are formed in bacteria.

According to a new report in Psychological Science, stress could make our financial troubles even worse. This study suggests that stress exaggerates the reflection effect; while exposed to stress volunteers were more conservative when choosing between potentially positive outcomes and were riskier when choosing between gambles that could result in a loss. These findings indicate [...]

Imagine a platoon of soldiers fighting in a hazardous urban environment who carry personal digital assistants that can display the location of enemy shooters in three dimensions and accurately identify the caliber and type of weapons they are firing. Engineers have developed a system that can give soldiers just such an edge by turning their [...]
