Scientists at University of Oregon discover one of the oldest known animal sex chromosomes in California two-spot octopus.

Researchers have identified a sex chromosome in the California two-spot octopus. This chromosome has likely been around for 480 million years, since before octopuses split apart from the nautilus on ...

What stands out the most about this ancient cephalopod sex chromosome is how little the chromosome has changed over time.

A study conducted by a research team at the Crick Institute identified important genes on the Y chromosome that regulate ...

Discover how researchers identified an octopus' ancient sex chromosomes and why their genetic history is such a mystery.

Female mammals typically carry two X chromosomes — one from each parent — and a new study suggests that the maternal X is linked to faster brain aging.

Researchers at the Crick have uncovered which genes on the Y chromosome regulate the development of sperm and impact fertility in male mice. This research could help us understand why some men don’t ...

Scientist have long tried to unlock the secrets of helping people live longer at the cellular level, where aging occurs in ...

A UCSF study reveals that maternal X chromosome expression may accelerate brain aging and cognitive decline. Female mice with ...

New research shows that female mice expressing only a maternal X chromosome experience faster brain aging and cognitive decline compared to those expressing both maternal and paternal X chromosomes.

The research suggest octopus and other cephalopods, like squid and cuttlefish, all rely on the ancient chromosome to ...
