(Phys.org) —Researchers have reconstructed the mitochondrial genome of a Middle Pleistocene cave bear using a bone sample found in Spain. This is the first time anyone has reconstructed such an old genome from a sample ...
A key biochemical enables bacteria to repair otherwise fatal damage to their DNA, including that caused by antibiotics. That is the finding of a study led by researchers at NYU Langone Medical Center and published May 20 ...
