A team of researchers from the U.S., China and Taiwan has found some rare instances of fathers passing mitochondrial DNA (mtDNA) to their offspring. In their paper published in Proceedings of the National Academy of Sciences, ...
Cigarette smoking is overwhelmingly the main cause of lung cancer, yet only a minority of smokers develop the disease. A study led by scientists at Albert Einstein College of Medicine and published online today in Nature ...
