For the first time, scientists solved the high-resolution structure of these compounds when they are actively bound to the 5-HT2A serotonin receptor on the surface of brain cells. This discovery is already leading to the exploration of more precise compounds that could eliminate hallucinations but still have strong therapeutic effects. Psilocybin – the psychedelic compound in mushrooms – has already been granted breakthrough status by the FDA to treat depression.

Researchers have identified how cells in our brains work together to join up memories of separate experiences, allowing us to make educated guesses in everyday life. By studying both human and mouse brain activity, they report that this process happens in a region of the brain called the hippocampus.

A multi-layered, virus-specific immune response is important for controlling SARS-CoV-2 during the acute phase of the infection and reducing COVID-19 disease severity, with the bulk of the evidence pointing to a much bigger role for T cells than antibodies. A weak or uncoordinated immune response, on the other hand, predicts a poor disease outcome.

Differences in biological sex can dictate lifelong disease patterns, says a new study by Michigan State University researchers that links connections between specific hormones present before and after birth with immune response and lifelong immunological disease development.
