Neurons in the anterior cingulate store social rank information to inform upcoming decisions. The findings could shed new light on social deficits associated with ASD and schizophrenia.

A challenge in materials design is that in both natural and manmade materials, volume sometimes decreases, or increases, with increasing temperature. While there are mechanical explanations for this phenomenon for some s...

Study reveals how psychedelic drug-induced changes in subjective awareness are rooted in specific neurotransmitter systems.

Psychedelics may find new, legitimate roles in treatment for anxiety, depression, stress disorders, addiction, and other mental and behavioral health problems. But ensuring they do requires developing rigorous, standardi...

Stroke can have many causes. An atherothrombotic stroke is caused by a clot that forms from plaques that build up within blood vessels in the brain. A new study suggests that people who have this type of stroke who also ...

In mice, social ranking in a group was linked to the results of competition, and certain neurons in the brain stored this social ranking information to inform decisions. Manipulating the activity of these neurons could i...

A small preliminary study has shown that a blood test may identify risk of stillbirth and placentitis in pregnant individuals who have had COVID-19. The finding builds on another study with similar results and could have...

An inhalable 'aerogel' loaded with DNA that encodes for the SARS-CoV-2 spike protein successfully induces an immune response against COVID-19 in the lungs of mice, according to new research. The team said its aerogel cou...

A research team has discovered novel metabolic mechanisms that contribute to how ovarian cancer escapes from immune attack, and how combination therapies can exploit these pathways to improve ovarian cancer treatment.

Individual Candida albicans yeast strains in the human gut are as different from each other as the humans that carry them, and some C. albicans strains may damage the gut of patients with inflammatory bowel disease (IBD)...
