[ExI] Can GLP-1 drugs slow ageing? Mouse study shows promise

[John Clark]

*The following is from the September 2, 2026 issue of the journal Nature: *

*"Animals treated with the GLP-1 drug semaglutide (marketed under the brand
names Ozempic and Wegovy), had a median lifespan of 834 days — 12% longer
than mice in the control group, which lived for a median of 742 days.Mice
that took semaglutide also did better than control animals on tests that
evaluated coordination, muscle function and how the body processes sugar.
[...]  The mice taking semaglutide during the study self-reduced their
calorie intake by 24%. So, to check whether this was the cause of the
observed effects, the authors put an extra, untreated group of mice on a
diet that matched the calorie-intake level of the GLP-1-treated mice. The
two groups showed similar longevity outcomes. However, the GLP-1-treated
mice performed better than did those in the diet group in several
experiments, including one testing spatial memory, in which animals had to
remember the location of the exit to a maze."*
