The dendritic arms of some human neurons can perform logic operations that once seemed to require whole neural networks.

In evolution, context is everything: Bacteria with neighbors evolve to rebuff viruses in a different way.

To scientists’ surprise, blended mixtures of cytoplasm can reorganize themselves into cell-like compartments with working structural components.

Researchers explored the zone between life and death, charted the mind’s system for arranging ideas and memories and learned how life’s complexity emerged.

An organized tide of brain waves, blood and spinal fluid pulsing through a sleeping brain may flush away neural toxins that cause Alzheimer’s and other diseases.

Machine learning and deep neural networks can capture and analyze the “language” of animal behavior in ways that go beyond what’s humanly possible.

New studies help to explain how microbes in the gut can shape a host’s fear responses.

Smallpox was eradicated relatively quickly, but other diseases have proved harder to eliminate. The reasons are a mix of biology and psychology.

New research makes a molecular connection between the brain and aging — and shows that overactive neurons can shorten life span.
