New results suggest that prion protein mutations differ in how likely they are to cause rare and fatal disorders.
Insects evolved earlier than previously suspected, and may have helped to shape Earth’s first terrestrial ecosystems.
Gene therapy can be used to transform some of a pig's regular heart cells into pacemaker cells, according to a new study in Science Translational Medicine.
Researchers have pinpointed a genetic mutation that may help explain why some men are less fertile than normal, a new study in the 20 July issue of the journal Science Translational Medicine reports.
The gene encodes a protein called beta-defensin 126, which coats the surface of sperm and helps them penetrate cervical mucus in women. Men with a variant of this gene, called DEFB126, lack beta-defensin 126, making it much more difficult for sperm to swim through the mucus and join with an egg.
