During consolidation, the brain produces new proteins that strengthen fragile memory traces. However, if a new experience occurs while an existing memory trace is being consolidated, the new stimuli could disrupt the consolidation process. Some memory consolidation occurs while we are asleep. But…

In order to guide us accurately through space, the brain needs a 'sense' of the speed of our movement. But how do such stimuli actually reach the brain? Researchers have now identified a signal pathway in mice that feeds speed information directly into the brain's navigation system.

In honey bee colonies, a single queen is laying eggs from which thousands of worker bees are born. At a young age, workers care for the brood, then build and defend the nest and eventually, towards the end of their lives, leave the safety of the nest to forage for food. This major step in their…

With winter approaching, bears all over the world are getting ready to hibernate. New research suggests that not all bears will spend entire winter in their dens, however, especially where baiting and other kinds of bear feeding is performed for hunting purposes and diversion from human settlements.
