Researchers use directed evolution to create a bacterial strain that substitutes a synthetic base for thymine.
The Nobel Prize winner who discovered the gene that encodes the major histocompatibility complex passes away at age 90.
Starving brain cells can stimulate hunger through a common cannibalistic act, possibly explaining why some dieters can’t resist temptation.
Pro-evolution bumper stickers and emblems are being removed from the cars of biologists in Florida.
While gut microbiota appear to have both positive and negative impacts on our health, in the guts of healthy, lean individuals, the good outweighs the bad. Gut bacteria, most of which reside in the large intestine, process many otherwise indigest
Gut bacteria that feed on healthy food appear to amplify the nutritional benefits of those foods. However, they also appear to amplify the undesirable effects of unhealthy food. Here are a few examples. Read the full story.
For more than 100 years, pathologists have observed cancer cells engulfing other live cells, but scientists are only now beginning to understand how it happens and what it means for tumorigenesis.
Using the strongest molecular binding partnership in biology to separate different cell types
Isolating specific cell types from a mass of plant or animal tissue is laborious and tricky. To study epigenetic changes and genes that are expressed differently in different cell lineages—such as cancer cells versus normal cells, or the two types of
