Scientists investigating a molecule known to play a key role in causing colon cancer have made a series of ground-breaking discoveries that could have major implications for future treatment of the disease.

How a cell achieves the coordinated control of a number of genes at the same time has long puzzled scientists. Researchers have discovered a surprising answer. Just as human engineers control devices ranging from dimmer switches to retrorockets using frequency modulated signals, cells tune the expression of groups of genes using discrete bursts of activation.

In pre-clinical studies, vitamin C appears to substantially reduce the effectiveness of anti-cancer drugs, say researchers.

Countries with strict social rules and behavioral etiquette such as the United Kingdom may foster drinking cultures characterized by unruly or bad behavior, according to a new report on alcohol and violence.
