In what could be a breakthrough in animal breeding, scientists have discovered a set of genetic regions responsible for animal tameness. This discovery should help animal breeders, farmers, zoologists, and anyone else who handles and raises animals to more fully understand what makes some animals interact with humans better than do others.
During desperate times, such as fasting or muscle wasting that afflicts cancer or AIDS patients, the body cannibalizes itself, atrophying and breaking down skeletal muscle proteins to liberate amino acids. A new study shows that muscle atrophy is a more ordered process than was previously thought.

New research documents a surprising chemical weapon used by some Amazonian poison frogs. The study identified for the first time a family of poisons never before known to exist in these brightly colored creatures or elsewhere in nature: the N-methyldecahydroquinolines. The authors then speculated on its origin in the frogs’ diet, most likely ants.

Men with insomnia and sleep duration of six or fewer hours of nightly sleep are at an increased risk for mortality, according to a new research.
Vast quantities of data are transferred in real time from telescopes around the world to a supercomputer in the Netherlands, where researchers combine the information to create high-resolution images of distant objects in space.

When it comes to concussions, children and teens require different treatment, according to international experts. The new guidelines say children and teens must be strictly monitored and activities restricted until fully healed. These restrictions include no return to the field of play, no return to school, and no cognitive activity.
