Is Diabetes Related to Artificial Sweeteners?

Mice given non-caloric sweeteners developed glucose intolerance more quickly than those given sucrose or glucose. In these animals the artificial sweeteners quickly altered the mouse microbiome in favor of pathways that enhance absorption of calorie rich glucose and short-chain fatty acids. Authors suggest this may help explain the diabetes epidemic, although this needs to be reproduced in humans. PositiveTip:…

Reversing Age-Related Memory Loss (In Mice)

Geneticists in Germany trained mice of different ages to solve a variety of cognitive tests. The oldest mice had the hardest time learning these tasks, and failed to activate genes that are important for memory.Treating these older mice with a specific molecule that repaired a specific histone modification defect in the mouse DNA resulted in significant…
