An interesting but preliminary biomarker study’s reception illustrates the challenges of conducting and communicating nuanced research in the era of social media.

Though scientists don’t yet know much about it, a newly described process called erebosis might have profound implications for how the gut maintains itself.

A sugar that’s less abundant in the blood of people with diabetes binds to SARS-CoV-2’s spike protein and disrupts the virus’s ability to fuse with cells.  

In two related studies, researchers describe huge chromosomal rearrangements and about 500 novel gene clusters in the octopus, squid, and cuttlefish genomes, which they say could help explain how they evolved their extraordinary brains.

Human data and experiments in mice challenge the common use of anti-inflammatory drugs to treat pain.

A brain area of Aedes aegypti responds specifically to components of human sebum, a study finds.

A growth factor found in the cerebrospinal fluid of young mice triggered the proliferation of myelin-making cells when injected into the brains of older mice.
