By comparing stem cells from six mammals of different sizes, scientists discovered stark differences in embryonic development paces.

Extra copies of four interferon receptor genes found on human chromosome 21 trigger developmental changes in a mouse model of Down syndrome.

Mycobacterium leprae appeared to reprogram the animals’ livers to a state partially resembling early development, resulting in healthy organ growth.

In the wake of Elon Musk’s takeover, many researchers are exploring their options with the open-source platform Mastodon.

Viral remnants make up 8 percent of the human genome, and a new study finds that these sequences are still active in healthy people.

Maternal infection during pregnancy may be associated with autism, as previous studies have suggested—but perhaps not in a causal way.

Researchers report they were able to make functional sperm in a dish, a feat previously only possible for mice.

The Rockefeller University geneticist is tracing the full lifespan of individual cells to better understand how and why humans age.

Researchers explore the idea that molecular patterns in individual cells could underlie the development of a left and a right in animals.

Researchers use imaging to show how actin fibers tilt and then swirl to create left-right asymmetry in the cell.

Mintz’s experiments over her six-decade career were foundational to cancer and genetics research.

Researchers provide evidence that the Alzheimer’s-associated protein calibrates a signaling pathway that is conserved across the animal kingdom.

In both a mouse model and the hospital records of more than 3 million children, researchers found a connection between strong immune activation in males and later symptoms of autism spectrum disorder.

Work in rodents shows that the bacteria living in a mother’s gut can produce immunomodulatory metabolites and influence the production of maternal antibodies—both of which can affect her offspring’s development.

Bacteria in the gut influence the production of antibodies and themselves secrete metabolites. In a pregnant woman, these compounds may influence immune development of her fetus.

Spontaneous waves of nerve impulses flowing across the retina help mouse pups practice motion detection for when they eventually open their eyes.

Human stem cells injected into early monkey embryos proliferate and contribute to multiple cell lineages over 20 days of embryonic development.
