The incidence of severe manifestations of COVID-19 increases with age. One mechanism of aging is the progressive shortening of telomeres, which are protective structures at chromosome ends.

Berberine is a compound produced by several plants; this study finds low-dose berberine increases lifespan in yeast, mice, and human cells and reverses biomarkers of aging.

Researchers investigated the impact of a bacterial metabolite on the aging process in worms, using green light exposure to control the activity of genetically engineered bacteria.

Deep learning algorithms can be used to explore individual DNA methylation landscapes in the context of aging, and they can potentially be used to estimate the risk of certain age-related events in the future.
