Genetic knockout experiments reveal a role for the protein in forming and maintaining synapses between motor neurons and muscle fibers in mice.

The muscle transmembrane protein Vangl2 helps organize the development and maintenance of connections between muscles and motor neurons, a study concludes.

The findings will likely help elucidate the effects of chromosome fusions, which can cause disease but have also contributed to evolution.

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.

Using stem cells and a bioreactor, researchers generated living embryos that survived for more than a week and began to develop internal organs.

An odorant found in the pee of pregnant mice—and in bananas—induces stress but also relieves pain in male mice, a study shows.

A series of rodent experiments showed that even with abundant food and water, personal space is essential to prevent societal collapse.

A new technique reveals cells’ precise locations and functions in the brain. Its developers have already used it to identify a previously unknown neuron type.

A new methodology combines existing techniques to reveal the specific function and location of multiple types of neurons at once.

An independent lab fails to replicate results suggesting mammals exposed to pathogens could pass on immunological protections through epigenetic mechanisms.

Offspring of animals subjected to a real or simulated pathogen were more able to fend off disease, a study finds.

Researchers have identified specific cells and neuropeptides involved in mediating the sneeze response in mice exposed to allergens or chemical irritants such as capsaicin.

A mouse study identifies the brain regions and specific signaling factors that regulate the sneeze response.

Researchers identify a role for PIEZO1 in tendon adaptation, and show that people with certain versions of the Piezo1 gene tend to be better jumpers.

Rather than relying on samples that need to be shipped in glass vials and on ice, researchers have developed a new method that allows mouse sperm to be sent easily at room temperature using standard mail delivery.

Obese mice that exercised while pregnant gave birth to pups that grew up free of the metabolic issues present in the adult young of sedentary obese mothers—possibly by staving off epigenetic changes to a key metabolic gene.

A pool of neural stem cells that ordinarily lies dormant in the brains of adult mice spawns two types of never-before-documented glial cells when artificially reactivated, potentially pointing to a novel mechanism of brain plasticity.

Some viruses, possibly even SARS-CoV-2, can sneak into the brain through the nose. Recent studies show that microglia are ready for them when they do.
