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.
Simple math shows how widespread vaccination can disrupt the exponential spread of disease and prevent epidemics.
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.
Near an Australian desert mining camp, wild dingoes are losing their fear of humans. Their genetic and behavioral changes may echo those from the domestication of dogs.
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.
Evolution settled on a genetic code that uses four letters to name 20 amino acids. Synthetic biologists adding new bases to DNA will be free to improve on nature — if they can.
