Researchers have discovered a new set of signals that cells send and receive to prompt one type of fat cell to convert fat into heat. The signaling pathway, discovered in mice, has potential implications for activating this ...
Yes, fat cells deep under your skin can sense light. And when bodies do not get enough exposure to the right kinds of light, fat cells behave differently.
A new Tel Aviv University study suggests that the genetic profiles of two extinct mammals with African ancestry—woolly mammoths, elephant-like animals that evolved in the arctic peninsula of Eurasia around 600,000 years ...
A technique that uses fluorescent dyes to measure the temperature inside living cells is helping to reveal the mechanism by which living organisms generate heat.
Once almost wiped out from existence, the mighty bison has recovered to become a symbol of pride for the American West and European conversation efforts.
(Phys.org) —Since leptin was discovered 20 years ago, more than 115,000 papers have been published on this protein in humans, and another 5,000 have appeared on leptin in mice.
(Phys.org) —In the winter, brown and black bears go into hibernation to conserve energy and keep warm.
(Phys.org) —If you asked a biologist what any given cell is going to do next, they might ask you first to tell them its electrical potential, oxygenation, pH, osmolarity or glucose concentration. Depending on how finely-scaled ...
When mammals are cold, they can employ physical changes to stay warm -- such as intense shivering. Like any form of aerobic exercise, though, "shivering thermogenesis" is especially challenging at high altitudes because there ...
A developmental biologist at New York Medical College is proposing a new theory of the origin of birds, which traditionally has been thought to be driven by the evolution of flight. Instead, Stuart A. Newman, Ph.D., credits ...
