Scientific field studying aging biology, seeking biomarkers, genetic factors, and drug or lifestyle interventions to extend lifespan and healthspan.
University of Illinois Chicago researchers estimate a 70-year-old woman in Sardinia's Bolotana has a 13.8% chance of reaching 100, versus 3.5% across Italy. With only 2,266 residents, the estimate swings by period, and for 2015-2019 it was 1.46%, ScienceAlert reported.

Kallel-led researchers found 287 gene changes unique to Jonathan, the 194-year-old Aldabra tortoise, touching DNA repair, inflammation, insulin and cancer. Because the baseline was just four other tortoises, the 287 are candidates to explain his slow ageing.

Osaka researchers found CD4 cytotoxic T lymphocytes rise from 4 percent to 17.6 percent of circulating T cells across the oldest age brackets. Outside immunologists want function, not just counts.

The $20mn round buys roughly 0.53 per cent of the company, and no product exists yet. Read the number as a reference price for pre-revenue bio-AI, not a verdict on the science.
Reality
An NIH-funded UC Berkeley team dosed old, healthy female mice, then fed a second group 24% fewer calories to match what the drug's appetite suppression achieved. The drug still did more on memory and blood sugar.

Researchers in Hong Kong and Georgia paired blood measurements with a Mendelian randomization arm. The male estimate survived where the female one stayed null. Neither arm looked at anyone taking the supplement.

Junyue Cao read 21 million cells from 14 organs and says aging arrives in discrete stages. If the staging holds, an intervention has a window rather than a dose.
