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.
As chemists tie the most complicated molecular knot yet, biophysicists create a “periodic table” that describes what kinds of knots are possible.
Evidence for life in 3.7-billion-year-old rocks appears to be crumbling away.
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.
Renee Reijo Pera has spent decades uncovering how the timing of embryonic development contributes to health and disease.
New work at the intersection of atmospheric science and ecology is finding that forests can influence rainfall and climate from across a continent.
By using the power of evolution to solve practical problems, three researchers opened new avenues to chemical discovery.
