1. Near-Death Evidence

This story examines a letter to the editor in Brain Communications that challenges a proposed evolutionary link between near-death experiences and thanatosis, the defensive behavior often called playing dead. The original idea suggests that some features of near-death experiences could be remnants of an ancient survival response seen across animals.

2. Pollution and Parkinson’s

A report from The Brighter Side examines long-term air-pollution exposure and the risk of Parkinson’s disease. Researchers at the University of Cambridge reviewed 26 Parkinson’s studies, along with smaller evidence sets on multiple sclerosis and motor neurone disease.

3. Hemispheric Organization

The bioRxiv preprint examines how language and attention are organized across the brain’s hemispheres. Using brain scans and family data from 987 participants, the researchers identified right-sided, left-sided, and bilateral attention patterns that were independent of handedness and varied by sex.
