What is the Longevity Research Library?

The Longevity China Research Library curates recent peer-reviewed studies on longevity, nutrition, exercise, sleep, and supplements. Each study is rated by evidence strength: Strong, Moderate, or Preliminary.

How are evidence levels determined?

Evidence levels are based on study type (meta-analysis, RCT, cohort study), sample size, journal impact factor, and reproducibility of findings.

How the APOE4 Gene May Speed Up Tau Tangles in Alzheimer's

In mouse and neuron experiments, researchers found a special proteasome on neurons that normally clears out tau protein before it forms toxic tangles. People with the APOE4 gene (the biggest genetic risk factor for Alzheimer's) have less of this cleanup machinery, and levels also drop with age. This may explain why APOE4 carriers are more vulnerable to Alzheimer's pathology.

New Trial Will Test Whether Taurine Improves Blood Sugar and Slows Aging

This is a protocol, not results, for a trial giving healthcare workers 3 grams of taurine daily for six months. Researchers want to see if it lowers HbA1c (a long-term blood sugar marker) and improves PhenoAge, a biological age estimate. The study uses a smart adaptive design that can stop early if taurine clearly works or clearly fails.

Just 5,700 Daily Steps Cut Death Risk By 13% In Older Adults

Looking at dozens of studies with over 367,000 older adults, regular walking was tied to lower risk of death, disease, and cognitive decline. Each extra 1,000 daily steps was linked to a 13% drop in death from any cause. Walking pace did not change the benefit, so slow walks counted too.

Exercise Linked to Younger Biological Age, But Effect Is Modest

Pulling together 44 studies on nearly 145,000 people, researchers found that more physical activity is tied to a younger biological age, but only on certain epigenetic clocks. The effect showed up clearly on GrimAge and Horvath clocks, but not on Hannum or PhenoAge. The size of the benefit was small, and most data came from snapshot studies, so we can't say exercise actually causes the slowdown yet.

What Centenarians' Immune Systems Reveal About Escaping Age-Related Disease

People who live past 100 tend to have immune systems that look surprisingly young. This review found they have less chronic inflammation, better cellular cleanup (autophagy), and gut bacteria patterns linked to healthy aging. Those living past 110 often have immune profiles resembling much younger adults.

Your Blood Is Both a Mirror and a Driver of How Fast You Age

Scientists are finding that the stuff floating in your blood, proteins, metabolites, and tiny vesicles, doesn't just reflect your age. It actively sets the pace of aging across organs. In animal studies, swapping old blood for young blood or filtering out pro-aging factors restored tissue function and even extended lifespan. Human trials using plasma exchange are now showing early promise for age-related decline.
