New research by European scientists is a first step towards forecasting the expression of all genes in a given organism and demonstrates that the genetic regulation that is crucial for correct embryonic development is more flexible than previously thought.

Individuals with weaker muscles appear to have a higher risk for Alzheimer's disease and declines in cognitive function over time, according to a new report.

Gifted young athletes are under increasing pressure to play only one sport year round. But a new study found that such specialization increases the risk of injury in junior tennis players.

Some patients can live for years with melanoma that has spread beyond the skin to other organs. Now it may be possible to identify which patients are more likely to survive by analyzing the activity of hundreds of genes involved in the immune response and gene proliferation.

A woman is six times more likely to be separated or divorced soon after a diagnosis of cancer or multiple sclerosis than if a man in the relationship is the patient, according to a study that examined the role gender played in so-called "partner abandonment." The study also found that the longer the marriage the more likely it would remain intact.

While astronomers have studied lightweight and heavyweight black holes for decades, the evidence for black holes with intermediate masses has been much harder to come by. Now, astronomers find that an X-ray source in galaxy NGC 5408 represents one of the best cases for a middleweight black hole to date.

Here's one you can try at home: Fill a dish with water and drop a small amount of flour onto the surface. The flour particles disperse rapidly, like a tiny starburst, and spread out over the liquid surface. [More]

Researchers have shown that the brain regions that have long been recognized as a center in which spoken or written words are decoded are also important in interpreting wordless gestures. The findings suggest that these brain regions may play a much broader role in the interpretation of symbols than researchers have thought and, for this reason, could be the evolutionary starting point from which language originated.
