Analyzing organoids has proven slow and cumbersome for scientists. But a new technique may speed things up, producing 3D images of hundreds of organoids per hour.

The human cells, engineered to respond to blue light, influenced rat behavior when stimulated.

A single amino acid substitution in a protein causes increased neuron production in the frontal lobes of humans compared to Neanderthals—a tiny difference that could have given our species a cognitive edge, researchers say.

Disturbing circadian rhythms in organoids and mice increases intestinal tumor growth, findings that may explain a recent rise in colon cancer among young adults, the researchers behind the work say.

The genes are involved in pacing the development of inhibitory and excitatory neurons. An imbalance in these two types of signaling is thought to play a role in autism.

Removal of the 14-day limit for culturing human embryos is one of the main changes in the revised recommendations from the International Society for Stem Cell Research.

The National Academies’ report touches on ethical issues raised by new technologies such as brain organoids and human-animal chimeras, and suggests that current regulatory oversight is sufficient.

Researchers determined that when introduced into damaged mouse or donated human livers, these lab-grown tissues could integrate into bile ducts and function normally.

Using CRISPR to swap an archaic variant of the NOVA1 gene into human stem cells, researchers create organoids with neurodevelopmental differences from those carrying modern DNA.

Researchers turn to familiar model animals, along with some fresh strategies, to develop countermeasures against SARS-CoV-2 and investigate the biology of infection.

The results are a proof-of-concept that the novel coronavirus can replicate in neurons, but it’s too soon to say whether this occurs in people with COVID-19.

By infecting glioblastoma cells but not healthy brain tissue, some form of the virus could serve a therapeutic purpose.

Stem cells from nine snake species respond to tissue culturing techniques previously used only on mouse and human stem cells.
