Researchers have shed new light on evolutionary processes in the last 50,000 years that have allowed some disease-causing genes to persist in human populations.
A study suggests that cells involved in the sexual development of Aspergillus fungi also play a role in producing chemicals that deter hungry predators.
A genetic analysis suggests that a rare blood cancer that affects immune T cells may be caused by exposure to smoking and aging-related mutations acquired during the early stage of production of new blood cells.
A new study shows how a type of protein acts as part of a previously unrecognised epigenetic mechanism that helps yeast adapt more quickly to changing circumstances.
