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.
An independent lab fails to replicate results suggesting mammals exposed to pathogens could pass on immunological protections through epigenetic mechanisms.
Researchers have identified specific cells and neuropeptides involved in mediating the sneeze response in mice exposed to allergens or chemical irritants such as capsaicin.
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.
Two studies show that Plasmodium—the genus of protozoans that cause malaria—have an internal sense of time that synchronizes with their host’s circadian rhythms and allows the parasites to collectively attack blood cells.
