A study published in the Proceedings of the National Academy of Sciences by scientists from Israel and Ghana shows that an evolutionarily significant mutation in the human APOL1 gene arises not ...

For a long time, evolutionary biologists have thought that the genetic mutations that drive the evolution of genes and proteins are largely neutral: they're neither good nor bad, but just ordinary ...

Knowledge is power — but only if you use it. We know about viruses and how they reproduce. We know about evolution through gene mutation and natural selection winnowing resulting variants. We know ...

Scientists showed that fixed mutations within a viral population most likely stem from how easy it is to acquire that mutation (i.e., mutation accessibility) rather than just its benefit. The ...

The influenza (flu) virus is constantly undergoing a process of evolution and adaptation through acquiring new mutations. Scientists at St. Jude Children's Research Hospital have added a new layer of ...

In the children’s game telephone, a whispered phrase like “I ate a pear” can quickly become “I hate bears” as it moves down a line of players. As genes are passed down from parents to offspring, they ...

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 ...
