Psychedelic-assisted therapy is the subject of renewed focus. It involves using psilocybin – a substance found in psychoactive fungi – or LSD to treat mental disorders. Numerous studies are currently underway, with talk rife of a “revolution in psychiatry”. However, doubts also persist. While some patients benefit from this therapy, others do not, and some patients even deteriorate as a result. Scientists led by Charité – Universitätsmedizin Berlin have now collated experiences from therapists around the world in an effort to identify suitable patients more precisely in the future. The researchers have described for the first time the profile of a good candidate for psychedelic-assisted therapy in an article published in Nature Mental Health*.
Invariant natural killer T (iNKT) cells are promising for cancer immunotherapy because they can coordinate broader immune responses, but sourcing enough functional cells is challenging. In a recent study, researchers from Japan showed that combining stem cell-derived iNKT cells with an immune-activating lipid compound can strongly suppress tumors in mice by training the body’s own T cells to recognize and remember cancer. These findings point to a more effective and scalable form of immunotherapy.
OAKLAND, Calif., May 7, 2026 -- A study published today in The Permanente Journal sheds light on what’s driving physicians to leave clinical practice early — and how those reasons are shifting. Researchers from the American Medical Association (AMA) analyzed survey responses from 971 clinically inactive physicians across all specialties who completed residency between 2000 and 2022. Their findings offer insights into why physicians are stepping away from patient care — or not entering the clinical workforce at all — especially as the nation faces a growing physician shortage.
Environmental health experts at Flinders University have found open windows and ventilation can reduce but not completely remove methamphetamine contamination on most hard surfaces of a car after an extended period.
In a new study, researchers tested various parts of a car’s interior to show concentrations in the air and surfaces exposed to controlled release of methamphetamine smoke. While levels generally dropped over time, the experts warn indirect exposure could still occur, in particular in textile or soft surfaces.
High concentrations of free fatty acid (FFA) in ketotic dairy cows activate endoplasmic reticulum (ER) stress pathways, contributing to mammary epithelial cell apoptosis and reduced milk yield. The study sets the stage for in vivo trials to validate ER stress inhibitors like Tauroursodeoxycholate (TUDCA) as practical solutions for managing ketosis and enhancing dairy cows health.
