The discovery that apparently dead cells can sometimes resurrect themselves has researchers exploring how far they can push the point of no return.
Viruses and other parasites may sync with their host’s biological clock — or reset it — to gain an advantage.
Stem cells seem to retain memories of old injuries to improve future healing. When that system goes wrong, chronic inflammation can result.
For 50 years, evolutionary theory has emphasized the importance of neutral mutations rather than adaptive ones at the level of DNA. Real genomic data challenges that assumption.
Using a new CRISPR-based technique, researchers are examining how the position of DNA within the nucleus affects gene expression and cell function.
A newly discovered mechanism may enable viruses to shuttle genes between bacteria 1,000 times as often as was thought — making them a major force in those cells’ evolution.
The availability of 16 new mouse genomes will help accelerate research into the genetic underpinnings of human traits and diseases.
How the ultra-cooperative behavior of ants, bees and other social insects could have evolved continues to challenge formal analysis. But a new theory about hedging bets against nature’s unpredictability may change the math and shift the debate.
