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.

Taste and smell receptors in unexpected organs monitor the state of the body’s natural microbial health and raise an alarm over invading parasites.

Activity in the visual cortex and other sensory areas is dominated by signals about body movements, down to little tics and twitches. Scientists are now rethinking how they study and conceive of perception.
