Aging men often lose the Y chromosome in a growing number of their cells—and it may be far more dangerous than once believed. This loss has been linked to heart disease, cancer, Alzheimer’s, and ...

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 of spindles to carefully separate the DNA after ...

Most people have some amount of Neanderthal DNA from the extinct cousins of modern humans who lived in Europe and Asia until ...

Human cells have two copies of each chromosome, and this balance is essential for genes to be expressed in the appropriate ...

Researchers found that interbreeding between Neanderthals and early modern humans favoured male Neanderthals mating with female modern humans.

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

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.

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 ...
