Polymers built inside the body through blood-catalyzed chemistry allow on-demand brain control

A longstanding mystery in mosquito biology has been solved, opening a potential new path for controlling mosquitoes and the diseases they spread. For decades, scientists believed that juvenile hormone, a chemical signal essential for mosquito reproduction, needed two different receptors to work: one inside the cell and another on its surface. The internal receptor was identified years ago, but the second remained elusive.

Why do cats often leave food unfinished? Many cat owners have experienced this puzzling behavior. Domestic cats are well known for eating multiple small meals throughout the day, a pattern thought to reflect their evolutionary origin from the African wildcat (Felis silvestris lybica), a solitary hunter that repeatedly captures small prey. It has also often been assumed that cats leave food unfinished simply because they have a small appetite or a capricious nature. However, the mechanism underly

Researchers at Cornell University have developed a powerful new genetic toolkit that allows scientists to study how genes function at the level of individual cells, an advance that could accelerate discoveries in development, neuroscience, and disease. The work is published in the journal eLife.

The four astronauts embarking on NASA's lunar flyby became on Monday the humans to travel farthest from our planet, as they get set to view areas of the moon never before seen by the naked eye.
