An unlikely team offers a controversial hypothesis about what enabled animal life to get more complex during the Cambrian explosion.
A newfound pair of giant viruses have massive genomes and the most complete resources for building proteins ever seen in the viral world. They have refreshed the debate about the origins of these cellular parasites.
The computer scientist Barbara Engelhardt develops machine-learning models and methods to scour human genomes for the elusive causes and mechanisms of disease.
For the first time, researchers see how proteins grab loops of DNA and bundle them for cell division. The discovery also hints at how the genome folds to regulate gene expression.
Stimulating part of the cortex as needed during learning tasks improves later recall. The finding reveals more about the brain’s memory network and points toward possible therapies.
The neuroscientist Erich Jarvis found that songbirds’ vocal skills and humans’ spoken language are both rooted in neural pathways for controlling learned movements.
Mechanical tension between tethered cells cues developing tissues to fold. Researchers can now program synthetic tissue to make coils, cubes and rippling plates.
The dizzying network of interactions within microbe communities can defy analysis. But a new approach simplifies the math and makes progress possible.
Compact genomes and tiny cells gave flowering plants an edge over competing flora. This discovery hints at a broader evolutionary principle.
