Evidence continues to mount that the Neanderthals, who lived in Europe and Asia until about 40,000 years ago, were more sophisticated people than once thought. A new study shows that Neanderthals chose to use bones from specific animals to make a tool for specific purpose: working hides into leather.

In many fish species body size plays an important role in sexual selection. Large individuals are preferred mating partners because they can enhance offspring survival by providing better quality resources than small individuals. While large females and males are often favored by sexual selection, fishing targets and removes these reproductively superior individuals.

The brain has a powerful ability to remember and connect events separated in time. And now, in a new study in mice, scientists have shed light on how the brain can form such enduring links.

A protein shredder that occurs in cell membranes of brain cells apparently also indirectly regulates the fat metabolism. The shredder, known as gamma-secretase, is considered a possible target for drugs against cancer and Alzheimer's disease. However, the results suggest that such agents may have long-range effects that need to be watched closely.
