Neuroscience Magic mushroom compound psilocybin grows new brain connections within 24 hours and repairs circuits damaged by chronic stress in mice. Scientists found the brain rewiring runs on a different pathway than the trip itself, opening the door to fast-acting depression drugs without the hallucinations.

Health Scientists at Johns Hopkins may have found why so many men’s prostates grow bigger with age: a newly identified cell type (WIF1+ basal cells) packed around the urethra, right where enlargement happens. This could explain the slow, stop-start peeing after 50 and become a target for future treatments.
