Genomic analysis of three Neanderthals shows unusually high modern human DNA on the X chromosome offering clues about ...

When bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting that involves construction ...

The model has the potential to transform the ability to study telomere biology, learn more about human aging, and ultimately help people preserve better health as they age.

The Iñupiat people of Alaska have long said that bowhead whales live two human lifetimes. That oral knowledge turned out to be conservative.

On the flipside, if telomeres are too long, it can also spell trouble because cancer cells require long telomeres to become longer lived, ‘immortal,’” says Mia Levine, associate professor of biology ...

In my clinical practice, many women planning pregnancy ask whether age can affect the health of their baby. Over the last few decades, it has become common for women to start families later because of ...

India, March 17 -- Selfish chromosomes bias genetic inheritance by manipulating the overdrive (Ovd) gene, a natural sperm quality control checkpoint.

They live in our houses, drink our water and even sleep in our beds. Cats have become an integral part of many households and ...
