Researchers insert functioning cone photoreceptors into the retinas of mice with advanced eye disease, improving their vision.

Manipulating the activity of neurons active during training had similar effects on the mice’s behavior.

Knocking out the receptor for a lipid that causes inflammation rejuvenates macrophage metabolism and restores cognitive function in an Alzheimer’s disease model.

A study finds that β-coronaviruses don’t use the normal secretory pathway, a possible explanation for some aspects of COVID-19 pathology.

Overactive immune cells identified in a mouse model and in postmortem human brain tissue may offer a potential therapeutic target for cognitive delays associated with the condition, researchers report.

When mice that had suffered a stroke were given blood from a healthy donor, they experienced less tissue and neurological damage.

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.
