Older mice have more new mutations -- changes in DNA sequence that occur in the individual rather than being inherited from a parent -- than younger mice in the genomes of their mitochondria, ...

A team of scientists at the University of Seville has identified an essential process that protects DNA integrity in reproductive cells, providing new clues about how organisms avoid genetic defects ...

The study reveals that these neighbouring cells are significantly more vulnerable to ageing-related damage, offering fresh ...

WOODS HOLE, Mass. -- While humans can’t renew their reproductive cells and organs if damaged, many invertebrates can as part of whole-body regeneration. Understanding how and why could have major ...

Scientists have known that sex-determination in vertebrates happens in the germ cells, a body's reproductive cells, and the somatic cells, the cells that are not reproductive cells. Yet they have not ...

Researchers clarified the interactions of the proteins Tejas (Tej), Vasa (Vas), and Spindle-E (Spn-E) in the formation of cellular compartments known as nuage and the processing of PIWI-interacting ...

When accounting for IVF, genetic testing, donor services, and reproductive tissue storage, the fertility market in the US is estimated to be more than $8B One in five individuals struggle to conceive, ...

The lifespan of a small roundworm that has been used as a key model organism in aging research is limited by how it self-sacrifices to feed its young, finds a new study. The lifespan of a small ...
