Life and death in the living brain

Scientists have demonstrated a direct link between the death of old neurons and their replacement by newly born ones in a living vertebrate. The study found that introducing a chemical inhibitor to slow apoptosis resulted in fewer new neurons being formed, providing insights into age-related diseases.

Diets bad for the teeth are also bad for the body

Research suggests that diets high in fermentable carbohydrates, such as sugar and starch, can lead to dental decay and contribute to chronic systemic diseases. A diet low in these carbohydrates may improve cardiovascular markers and reduce body fat. Dental problems can serve as an early warning sign for dietary imbalances.

Parental guidelilnes, consequences may be why fewer black teens smoke than whites

A University of Washington study found that black teens are less likely to start smoking as adolescents due to parental guidelines and consequences. Teens who associate with deviant peers are more likely to smoke, regardless of race. Parents can reduce their teen's likelihood of smoking by setting clear guidelines and maintaining a str...

Researchers gain genome-wide insights into patterns of the world's human population structures

Researchers used sophisticated statistical analyses to study genomic patterns of human population structure, revealing 18 significant axes of variation. These findings provide insights into the history of human evolution, evolutionary forces shaping local populations, and geographic correlations with genetic variation.
