Most lethal mutations in wild fruit flies are driven by newly transferred jumping genes, not small DNA errors, according to a ...

Scientists from the Broad Institute of MIT and Harvard in Cambridge, Massachusetts, have identified novel mutations in bacteria that promote the evolution of high-level antibiotic resistance. The ...

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 ...

Rachel Robson, assistant professor of biology at Morningside College, and Susan Burns, associate dean for academic affairs, collaborated on an article that was published in the May issue of the ...

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 Centers for Disease Control and Prevention recently recommended that everyone 6 months and older get an updated vaccination this fall against COVID-19 that is formulated to combat the most ...

Duke researchers find a surprising genetic source of lethal mutations in fruit flies, with possible implications for conservation and health Scientists have puzzled for decades over a basic ...

There is a long-standing debate in biology about the relative importance of existing variation versus new mutations in evolution. Now this has been put to the test in an experiment with bacteria that ...

Scientists have identified a genetic mutation that helps protect the brain function of animals that live in high-altitude, ...
