Groundbreaking research shows that as men age, harmful genetic mutations in sperm become more common—not just from random ...

Long before factories, mines, and cars filled the air with pollution, our distant ancestors were already living with a silent ...

(Memphis, Tenn.—July 28, 2023) The influenza (flu) virus is constantly undergoing a process of evolution and adaptation through acquiring new mutations. Scientists at St. Jude Children’s Research ...

A groundbreaking study published in this week’s issue of PNAS by scientists from Israel and Ghana shows that an evolutionarily significant mutation in the human APOL1 gene arises not randomly but more ...

Some animals aren’t just lucky, they’re biological masterpieces of adaptation. These creatures thrive in extreme conditions through genetic mutations and behavioral evolution that scientists are still ...

Harmful genetic changes in sperm become substantially more common as men age because some are actively favored during sperm ...

In a recent study posted to the medRxiv* preprint server, researchers investigate whether transmissible severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants developed during ...

Our brains evolved for complex thought and language - but the same genes that made us smarter may have increased mental illness risk.

The study of experimental evolution in Escherichia coli has provided unprecedented insights into the mechanisms of adaptive mutations, elucidating how populations diverge and optimise their fitness ...

The sun is located about 26,000 light-years from the center of our galaxy, aka the Milky Way, and its orbit is close to ...

Scientists in Helsinki studied nearly 400 dog families to see how new DNA mutations arise in puppies. They found that older ...
