This article explores two fascinating frontiers in neuroscience: A groundbreaking ALS study where scientists reactivated developmental genes (ISL1 and LHX3) to “rejuvenate” motor neurons, reducing stress and delaying disease progression in mice. And a new framework for understanding near-death experiences (NDEs), showing how neurobiology, evolution, and psychology combine to create profound, life-altering experiences at the edge of consciousness.

A new Harvard study reveals that the brains of Alzheimer's patients are deficient in lithium because the element gets trapped by amyloid plaques. In mouse models, a low dose of a special form called lithium orotate bypassed these traps, successfully reducing plaques and inflammation while restoring memory. This research suggests that addressing this lithium deficiency could be a promising new approach to treating Alzheimer's disease.
