How We Score
How we vet the research — transparency first
A Bile Acid Supplement in Mom's Diet May Extend Her Offspring's Lifespan in Fruit Flies
Maternal bile acid supplementation in fruit flies produced robust lifespan extension in offspring via a specific metabolic gene—an intriguing proof-of-concept with real mechanistic insight, but it's early-stage, needs replication, and …
DunedinPACE epigenetic clock best predicts cognitive decline in older adults
This early-stage study identifies DunedinPACE as a promising DNA-based marker for cognitive aging, but the findings are preliminary and need validation by other researchers before using the test to predict …
A blood test for cellular aging predicts disease and mortality risk
This is promising early-stage research suggesting a blood test could measure cellular aging and predict serious disease—but it's not yet peer-reviewed and needs independent confirmation before relying on it clinically. …
Can senolytic drugs prevent bone loss in aging and gum disease?
Senolytic drugs show promise for age-related bone loss in mice, but don't work for bone loss driven by active infection and inflammation. This suggests that clearing senescent cells alone won't …
How immune cells called NK cells shape healthy aging
This thoughtful review explains how your immune cells called NK cells age and become less effective, contributing to age-related disease, and suggests measuring NK function could help predict immune health—but …
Growing human aging in a chip: A new lab model to test longevity drugs
This is a clever engineering feat that could accelerate testing of anti-aging drugs by compressing human aging into days instead of decades, but it's an early-stage tool that must be …
How Planarians Lose Fertility with Age—and How to Reverse It
This intriguing study shows that planarian reproductive aging stems from a drift in the body's positional 'map' rather than irreversible damage—and the process can be reversed. While promising as proof-of-concept, …
How fat tissue controls aging through a molecular switch for insulin
This is solid foundational research showing how fat tissue acts as a control center for aging via an insulin-signaling dimmer switch. It's a promising lead for understanding interorgan aging mechanisms, …
How caloric restriction preserves liver and kidney health in aging mice
This is a well-designed mouse study showing that calorie restriction slows tissue aging in the liver and kidneys through mechanisms involving SIRT1 activation and reduced cellular senescence—supportive but incremental evidence …
Can saliva measure biological aging as well as blood?
This preprint shows that saliva-based biological age tests give different results than blood tests, so they shouldn't be used interchangeably—but it's too early to draw firm conclusions since the study …
Testing Three Anti-Aging Drugs in Older Adults: A Clinical Trial Protocol
This is a well-designed but early-stage clinical trial protocol testing whether three anti-aging drugs can reverse aging biology in older adults—no results yet. It's a promising step toward human evidence, …
How mitochondrial DNA variants affect telomere length in human cells
This early-stage lab study suggests that variations in mitochondrial DNA inherited from your parents might influence how long your telomeres stay and thus how quickly cells age—but the evidence is …
Naked mole-rats handle cell stress differently: a closer look at their autophagy system
This is a clever proof-of-concept study showing that naked mole-rat cells handle stress in a distinctive way involving reversible vacuoles—an intriguing clue to their longevity. However, it's very early-stage work …
How CMV Drives Aging in HIV Patients—And What We Can Do About It
CMV is a hidden driver of accelerated aging in people with HIV, but it's druggable: early trials of antivirals and vaccines show promise, and larger studies could transform care. This …
Can senolytic drugs restore fertility in female mice with fatty liver disease?
A mouse study suggests senolytic drugs might improve fertility in females with fatty liver disease by reducing cellular aging in the ovaries, though they don't actually fix the liver disease. …
Can we reverse aging by partially reprogramming cells?
Partial reprogramming is a promising concept for reversing aging at the cellular level, with encouraging early results in animals. However, it remains largely unproven in humans—think of this as a …
Rapamycin reduces age-related motor decline in mice, especially in females
Rapamycin preserved movement and motor control in aging mice, particularly in females, seemingly by reducing cellular stress in the brain. This is encouraging but still preliminary—animal findings require human testing …
Reversing cell aging in stem cells using temporary genetic reprogramming
This is a promising proof-of-concept for temporarily 'resetting' aging in stem cells using non-integrating viral vectors, but it's early-stage laboratory work. Before this can help patients, researchers need to test …
Natural compound DMB reduces cellular aging by activating DNA repair protein FEN1
This is a solid proof-of-concept study showing a natural compound can reduce cellular aging markers in the lab and extend lifespan in worms—promising enough to justify further study, but too …
How chemical marks on RNA control telomeres and aging
This thoughtful review proposes that chemical tags on RNA—not just DNA mutations—are key regulators of telomere aging, and highlights promising research directions. However, it presents no new experimental proof; the …
