The secret to a longer lifespan? Gene regulation holds a clue

Natural selection has produced mammals that age at dramatically different rates. Take, for example, naked mole rats and mice; the former can live up to 41 years, nearly ten times as long as similar-size rodents such as mice.

How three mutations work together to spur new SARS-CoV-2 variants

Like storm waves battering a ship, new versions of the SARS-CoV-2 virus have buffeted the world one after another. Recently, scientists keeping tabs on these variants noticed a trend: Many carry the same set of three mutations. ...

A new mathematical model of cellular movement

A mathematical model that describes how cells change their shape during movement suggests that the movement is mainly driven by the contraction of the skeletal proteins, called "myosin." The new model developed at Penn State ...

Water processing: Light helps degrade hormones

Micropollutants in water often are hormones that accumulate in the environment and may have negative impacts on humans and animals. Researchers of Karlsruhe Institute of Technology (KIT) and Leibniz Institute of Surface Engineering ...

Mutations across animal kingdom shed new light on aging

The first study to compare the accumulation of mutations across many animal species has shed new light on decades-old questions about the role of these genetic changes in aging and cancer. Researchers from the Wellcome Sanger ...

Are egg cells in aging primates protected from mutations?

New mutations occur at increasing rates in the mitochondrial genomes of developing egg cells in aging rhesus monkeys, but the increases appear to plateau at a certain age and are not as large as those seen in non-reproductive ...

Metabolism found to regulate production of killer cells

In a recent study from Lund University in Sweden, researchers discovered that metabolic changes affect how blood cells are formed during embryonic development. They found a previously unknown metabolic switch with a key role ...
