A major evolutionary theory says most genetic changes don’t really matter, but new evidence suggests that’s not true. Researchers found that helpful mutations happen surprisingly often. The twist is ...

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 ...

Mitochondria are known as the body’s “energy factories,” and their function is essential for life. Inside mitochondria, a set of complexes called the oxidative phosphorylation (OxPhos) system ...

The analysis revealed that about 2 per cent of sperm from men in their early 30s contained disease-causing mutations. That figure rose to between 3 and 5 per cent in middle-aged men (43 to 58 years) ...

Researchers discover that insect sex systems influence the speed of mitochondrial evolution, impacting biodiversity tracking ...

The stability of ribonucleoprotein complexes of SARS-CoV-2 nucleocapsid proteins differs among variants of concern and the viral evolution of nucleocapsid protein can be understood in the framework of ...

A 30-year-long study of a small population of marine snail shows how evolution can adapt to environmental changes quite rapidly. This study revealed how a specific ecotype of the snail changed its ...

Research on SARS-CoV-2 in zoo tigers, lions, and hyenas shows rapid viral evolution and adaptation, offering insights into cross-species transmission dynamics.

Researchers report that phage resistance in ocean bacteria can alter growth, metabolism and sinking behavior, revealing a ...
