Summary: New mouse study shows woodsmoke causes lasting brain inflammation and chemical changes, which may explain long-term effects seen in humans after smoke exposure. Major Findings: Woodsmoke Causes Lasting Brain Inflammation & Chemical Changes in Mice Smoke from wildfires and wood-burning stoves may have lingering effects on the brain, according to new research in mice. …
Summary: Advances in brain-computer interface (BCI) technology could one day give voice to those who have lost the ability to speak. New research brings us one step closer to this goal by reconstructing identifiable words and sentences directly from brain activity. Major Findings: Researchers optimized deep learning models to reconstruct speech sounds from brain recordings …
Buddhist meditation practices have been shown to create different states of consciousness. A new study looked at how traditional Buddhist meditation affects how the brain processes sounds. The results show that these meditations change brain activity in a way that tunes out sensory information. Key Facts: 115 Tibetan Buddhist monks with at least 3 years …
A new report from the CDC provides insight into suicide rates among different industries and occupations in the United States. The key takeaways: Suicide rates have increased 40% from 2000 to 2017 among working-age adults (ages 16-64).
