In what could be a breakthrough in animal breeding, a team of scientists from Germany, Russia and Sweden have discovered a set of genetic regions responsible for animal tameness. This discovery, published in the June 2009 issue of the journal Genetics, 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. It may also lead to more precise breeding strategies designed to pass specific genes from one generation to the next as a way to produce tame animals.
When female tiger salamanders choose a mate, it turns out that size does matter – tail size that is – and that’s not the only factor they weigh.
Researchers at Oregon State University have made a fundamental new discovery about how birds breathe and have a lung capacity that allows for flight – and the finding means it’s unlikely that birds descended from any known theropod dinosaurs.
Men with insomnia and sleep duration of six or fewer hours of nightly sleep are at an increased risk for mortality, according to a research abstract that will be presented on June 8, at Sleep 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies.
Research led by a leading expert on the positive benefits of napping at the University of California, San Diego School of Medicine suggests that Rapid Eye Movement (REM) sleep enhances creative problem-solving. The findings may have important implications for how sleep, specifically REM sleep, fosters the formation of associative networks in the brain.
