Every species develops at its own unique tempo, leaving scientists to wonder what governs their timing. A suite of new findings suggests that cells use basic metabolic processes as clocks.

The reshuffling of neurons during fruit fly metamorphosis suggests that larval memories don’t persist in adults.

With embryolike constructs built entirely from stem cells, researchers can revolutionize our understanding of development. But how close to an embryo is too close?

Changes in the 3D structure of their genome gave skates and rays their distinctive winglike fins and pancake flatness.

A survey of prehistoric bones reveals that T. rex and some of its cousins had more than one way to reach enormous sizes. Evolution may have preserved that variation in modern animals too.

Queen ants live far longer than genetically identical workers. Researchers are learning what their longevity secrets could mean for aging in other species.

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.

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

With stem cell technology and lab-grown brain organoids, Sergiu Paşca seeks the causes of autism and other neuropsychiatric conditions.
