Comparisons between modern humans and Neanderthals are usually meant as either an insult or a joke. But a new study suggests that many people today still harbor bits of Neanderthal DNA that affect their health. These remnants of ...
U.S. researchers say they used epithelial stem cells to regenerate different cell types of human skin and hair follicles that may help those going bald. Dr. Xiaowei "George" Xu, associate professor of pathology and laboratory medicine ...
THURSDAY Jan. 23, 2014, 2014 -- Researchers who identified five new genes linked to belly fat say their findings could help efforts to develop medicines to treat obesity or obesity-related diseases such as heart disease, diabetes and ...
Stem cells can turn into heart cells, skin cells can mutate to cancer cells; even cells of the same tissue type exhibit small heterogeneities. Scientists use single-cell analysis to investigate these heterogeneities. But the method is still ...

Sleeping during the day -- a necessity for jet-lagged travelers and those who work overnight shifts -- disrupts the rhythms of about one-third of your genes, a new study suggests. What's more, shifted sleep appears to disrupt gene ...
Biologists have studied the functionality of a poorly understood category of genes, which produce long non-coding RNA molecules rather than proteins. Some of these genes have been conserved throughout evolution, and are present in 11 ...
