"This selection methodology is a roadmap to improving the breeding of domesticated animals," Muir said. "The tool also could allow us to domesticate more species as readily available fo...

Researchers publish first working model that explains how biological clocks work

...nown for decades that biological clocks govern the behavior of everything from humans to lowly bread mold. These ticking timekeepers hold the key to many diseases, annoy passengers on intercontinental flights and can mean life or death for small creatures trying to survive in nature. Despite the importance ...

Scripps research team discovers a chemical pathway that causes mice to overeat and gain weight

During continuous monitoring of temperature and motor activity, the researchers realized that the mice without the EP3 receptors were more active during the light hours-the nocturnal mice's "night"-and, more importantl...

Adaptation to global climate change is an essential response to a warming planet

... just one aspect of that future by controlling the behavior of the climate," Sarewitz said. Policy discussions on climate change in the 1980s included adaptation as an important option for society. But over the past two decades, the idea of adapting to global environmental changes has become problematic fo...

Male sweat boosts women's hormone levels

"Many people argue that human pheromones don't exist, because humans don't exhibit stereotyped behavior. Nonetheless, this male chemical signal, androstadienone, does cause hormonal as well as physiological and ...

And indeed, observations of behavior exhibited by this chiclid species showed that related parents were more cooperative and invested more resources in parenting than did non-related parents. Together, the findings suggest that, somewhat unusually, active inbreeding is advantageous in t...

Brain's reward circuit activity ebbs and flows with a woman's hormonal cycle
