A new radiation-based mechanism adds to the ways that amino acids could have been made in space and brought to the young Earth.

Momentum for new ideas in Alzheimer’s research joined advances in neuroscience, developmental biology and origin-of-life studies to make 2022 a memorable year of biological insights.

The ecologist Holly Moeller studies microorganisms that expand their range by absorbing organelles and gaining new metabolic talents from their prey.

The neural representations of a perceived image and the memory of it are almost the same. New work shows how and why they are different.

After decades in the shadow of the reigning model for Alzheimer’s disease, alternative explanations are finally getting the attention they deserve.

Researchers discover that to sharpen its control over precision maneuvers, the brain uses comparisons between control signals — not the signals themselves.

New research in fish suggests that gut microbes can have a crucial early influence on the brain’s social development.

Supergenes that lock inherited traits together are widespread in nature. Recent work shows that their blend of genetic benefits and risks for species can be complex.

Marine bacteria normally seen as single cells join together as a “microscopic snow globe” to consume bulky floating carbohydrates.
