Aging compromises the lymphatic vessels (green) in tissue called the meninges (blue) surrounding the brain, disabling waste drainage from the brain and impacting cognitive function. Researchers at WashU Medicine boosted lymphatic vessel integrity (bottom) in old mice and found improvements in their memory compared with old mice without rejuvenated lymphatic vessels (top).

Boosting Brain Waste Removal Enhances Memory in Older Mice

Research opens door to developing therapies for neurodegenerative diseases As aging bodies decline, the brain loses the ability to cleanse itself of waste, a scenario that scientists think could be contributing to neurodegenerative conditions such as Alzheimer’s disease and Parkinson’s disease, among others. Now, researchers at Washington University School of Medicine in St. Louis report they have found a way around that problem by targeting the network of vessels that drain waste from the brain. Rejuvenating those vessels, they have…

Discovering Nature’s Magical Numbers with Ian Stewart

Mathematician Ian Stewart talks to Nature Science Update about snowflakes, sticklebacks and a new kind of science.

Ian Stewart was turned on to mathematics at the age of seven. A broken collarbone freed him from an uninspiring teacher allowing his mother to ignite his interest in numbers while he was laid up at home.

His writing career began with a series of how-to manuals for now-defunct early 1980s microcomputers. It has since broadened into popular science and science fi
