The long, variable times that some diseases incubate after infection defies simple explanation. An idealized model of tumor growth offers a statistical solution.
Even with no one in charge, army ants work collectively to build bridges out of their bodies. New research reveals the simple rules that lead to such complex group behavior.
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.
