Emory scientists have identified a function for a mysterious DNA modification in fruit flies' brain development, which may provide hints to its role in humans.
The results are scheduled for publication in Molecular Cell.
Epigenetics may mean "above the genes," but a lot of the focus in the field is on DNA methylation, a chemical modification of...
Naked mole-rats live in colonies of two breeders and around 300 non-breeding workers. Although the breeding pair carries the metabolic cost of reproduction and, in the queen's case, lactation, they live longer than non-breeders and remain fertile throughout their lives. Researchers at the Leibniz Institute on Aging in Germany investigated the genetic mechanisms beneath this...
A new dinosaur called Lingwulong shenqi or 'amazing dragon from Lingwu' has been discovered by an Anglo-Chinese team involving UCL.
The announcement, published in Nature Communications, reports the surprising discovery of the new dinosaur which roamed the Ningxia Autonomous Region, northwest China, approximately 174 million years ago. This is in a place they were never thought...
For a small, reddish-beaked bird called the zebra finch, sexiness is color-coded. Males have beaks that range from light orange to dark red. But from a female's point of view, a male's colored bill may simply be hot, or not, new findings suggest.
Due to a phenomenon called categorical perception, zebra finches partition the range of...
Images of baby animals reduces people's appetite for meat say researchers, who found that the effect is much stronger for women than for men.
Animal rights groups often use images of lambs and calves but there has been little evidence for their effectiveness in their campaigns.

Animals who share the task of parenting do a better job than parents who do so on their own, according to a study of insects.
Offspring raised by both parents grow to a healthier weight and are more likely to reach adulthood than those raised by one parent, research into beetles has found.
The research is the...
