What is NAD?

The XPrize Healthspan—which will split $101 million among teams developing therapeutics to restore muscle, cognitive, and immune function in older adults—has named 10 teams receiving $1 million each.

The combination of dichloroacetate, metformin, and ABT-263 eliminates cancer cells and age-promoting senescent cells while improving endurance and extending lifespan in mice.

By examining chemical tags on DNA that modulate our genes, scientists have discovered which genes are most affected by aging across more than a dozen human tissues.

Scientists are researching ways to regrow the thymus, an immune organ that vanishes with age, to suppress the tolls of aging.

A purported longevity drug, rapamycin, alters immune cells associated with cancer and reduces brain inflammation in mice.

Advocates say peptides offer significant benefits against aging, while researchers warn that these claims outpace the evidence.

Danish aging expert Morten Scheibye-Knudsen shares seven ways to slow aging, including taking NR (nicotinamide riboside) and the diabetes medication metformin.

The NAD+ (nicotinamide adenine dinucleotide) precursor nicotinamide prevents skin aging, in part by targeting age-promoting senescent cells in mice.

An engineered enzyme reverses age-related protein damage that researchers have long thought irreversible in human eye, skin, and artery tissues.

Glycine, an amino acid shown to extend the lifespan of mice, moderately extends the lifespan of flies and counters brain and muscle degeneration in aged rats.
