What is the Longevity Research Library?

The Longevity Austria 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.

Astaxanthin May Protect Aging Brains and Livers by Calming Oxidative Stress

In rats given a chemical that speeds up aging, astaxanthin (the red pigment in salmon and shrimp) reduced damage to the brain and liver. It worked about as well as vitamin E and improved memory in the water maze test. The benefits disappeared when researchers blocked a specific antioxidant pathway, confirming how it works.

Curcumin and Ginger May Help Memory, But Not Other Brain Functions

Looking at 18 trials, researchers found that compounds from the ginger family, including curcumin and turmeric, modestly improved memory in adults. The same compounds did not help with attention, executive function, or overall thinking. The authors caution the evidence is shaky due to small studies and big differences in how curcumin was prepared.

Healthy Lifestyle Didn't Change Brain Scans, But Still Helped At-Risk Seniors

In older adults at risk for cognitive decline, a two-year program of exercise, better diet, and social engagement didn't visibly change brain biomarkers like amyloid or shrinkage. But people who started with smaller hippocampi (the brain's memory hub) got more cognitive benefit from the structured version. So the lifestyle changes may help thinking even without obviously reshaping the brain.

Staying Active in Your 40s and 50s Tied to Sharper Thinking Decades Later

Pooling data from eight studies covering over 33,000 people, researchers found that higher physical activity in midlife was linked to modestly better memory, mental processing speed, and overall thinking ability later in life. The effects were small but consistent across multiple cognitive domains. However, the results for executive function and verbal fluency weren't meaningful. Almost all studies relied on self-reported exercise, and only one looked at men and women separately.

Your Brain May Slow Down Years Before a Heart Attack or Stroke

In older adults, thinking skills started declining 3 to 8 years before they had a major cardiovascular event like a stroke or heart failure. The drops showed up in memory, processing speed, and verbal fluency compared to people who stayed healthy. This hints that heart disease and brain aging share deep roots, and subtle cognitive changes might be an early warning sign.

exercise

Why Even One Workout Sharpens Your Thinking, According to Research

A single session of moderate to vigorous exercise reliably boosts executive function, processing speed, and working memory in adults. Cardio led the pack, but resistance training also improved executive function in many trials. The brain benefits seem tied to short-term spikes in BDNF, lactate, and prefrontal brain activity. So even one workout appears to give your brain a temporary lift.

Why Your Skin Never Forgets Inflammation, Even Years Later

In mice, skin stem cells can hold lifelong "memories" of past inflammation like psoriasis flares. These memories are stored as epigenetic changes. Specific DNA sequences rich in CpG patterns keep the memory accessible through cell divisions. This means once skin has been inflamed, its stem cells stay primed to react faster and stronger to future triggers.

Worse Metabolic Syndrome Tied to Faster Cognitive Decline in Older Adults

Among Chinese adults over 60, having more severe metabolic syndrome was linked to faster mental decline over several years. The connection held for both overall cognition and memory specifically. People in the worst quarter of cumulative metabolic syndrome scores declined in memory about three times faster than those in the best quarter. These findings come from two large studies tracking participants for up to eight years.

How Your Immune System Rewires Itself from Birth to Old Age

Researchers mapped immune cells at the single-cell level across the human lifespan, from mid-fetal development through late adulthood. T cells showed the biggest age-related changes. A specific subset of CD8 memory T cells appeared protective in young adults, while inflammatory monocytes ramped up with aging. A previously unknown subset of immune-suppressing natural killer cells was especially common in early childhood.
