How We Score
How we vet the research — transparency first
Can you breed bugs for more babies without losing lifespan? A surprising answer from predatory insects
This insect study found that selective breeding can produce bugs with far more offspring without the typical cost of shorter lifespans—a finding that surprises evolutionary biologists. While promising for pest …
Engineering immune cells to restore brain function in aging
A creative proof-of-concept in mice showing that engineered immune-targeting proteins can reduce brain aging and improve cognition. This is promising foundational work, but it's too early to know if it …
How Mouth Bacteria May Link to Frailty and Cognitive Decline in Older Adults
This paper announces a systematic plan to search the scientific literature for evidence linking mouth bacteria to aging-related frailty, muscle loss, and cognitive decline. The actual review hasn't been done …
How Aging and High Blood Pressure Damage Kidneys Through Cellular Senescence
This study provides preliminary evidence that cellular senescence accumulates in aging kidneys, especially under hypertension, correlating with progressive kidney damage—but it doesn't yet prove senescence causes the damage. More research, …
How IL-2 signals B cells to fight inflammation and may protect against autoimmune disease
This study reveals that IL-2 helps age-associated B cells produce anti-inflammatory signals, and losing this pathway worsens autoimmune neuroinflammation in mice. While intriguing for understanding how to reduce chronic inflammation …
How immune cells in the brain age and a new way to slow that process
This review spotlights an intriguing early-stage idea: tweaking the brain's immune system might slow aging by restoring T cell function and reducing unhelpful inflammation in microglia. It's a promising research …
