Bear genes show circadian rhythms even during hibernation

A genetic study found that grizzly bears' energy production follows a daily pattern even during hibernation, with a blunted amplitude and shifted peak. This suggests that the circadian rhythm helps bears conserve energy while still maintaining some metabolic function.

How cell identity is preserved when cells divide

A new MIT study proposes a theoretical model that helps explain how cells maintain the memory of their cell type despite losing chemical modifications during DNA replication. The research team suggests that the 3D folding pattern of the genome determines which parts will be marked by these chemical modifications.

The genomic secrets to how the muskox mastered living on the edge

A team of researchers analyzed whole genomes of over 100 muskoxen to explore their evolutionary history. They found that the muskox lost a significant proportion of its genetic diversity in the last 20,000 years, with present-day populations having only about a third of the diversity of ancient Siberian genomes.

Study reveals broader impact of Alzheimer’s on brain function

Researchers at The University of Texas at Dallas discovered distinct changes in brain network patterns associated with early-stage Alzheimer’s disease, affecting sensory and motor processing.
