Researchers have developed a magnetic method for influencing deep-brain circuits without permanently implanted electrodes. A magnetic field may offer a new way to reach circuits buried deep within the brain without permanently implanting electrodes. An international research team injected magnetic nanoplatelets into a targeted brain region and used them to improve movement problems in mice [...]

A new study strengthens the case for exercise as a critical way to protect the brain from age-related decline, including dementia and Alzheimer’s disease. During sleep, the brain activates a cleanup network that helps remove accumulated waste. A review led by Victoria University (VU) researcher Dr. James Broatch examined whether exercise could strengthen this glymphatic [...]

Paleontologists have unearthed a remarkably preserved fossil snake in Brazil that is reshaping ideas about how the earliest snakes lived and complicating the long-running debate over whether their ancestors burrowed underground, swam in the sea or crawled the surface.
