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.
The availability of 16 new mouse genomes will help accelerate research into the genetic underpinnings of human traits and diseases.
