Dietary Spermidine Boosts Cognition in Insects and Rodents
Ruth Williams | Apr 15, 2021
Mice and flies given the polyamine in their diet have increased brain cell metabolism and cognitive function, and epidemiological data hints at a similar benefit in humans.
Pharma Looks to Inflammasome Inhibitors as All-Around Therapies
Rachael Moeller Gorman | Apr 1, 2021
Many major biopharmaceutical companies are developing or acquiring drugs that target the NLRP3 inflammasome, a large intracellular complex that researchers say can spark inflammation and stoke diseases of lifestyle and aging.
Genetic Reprogramming Restores Vision in Mice: Study
Max Kozlov | Dec 6, 2020
