How We Score
How we vet the research — transparency first
How Long-Lived Whales Evolved Cancer-Fighting Genes
This is solid evolutionary detective work suggesting long-lived whales evolved superior versions of cancer-fighting genes, but it's still early-stage lab evidence. Don't expect human treatments from this finding soon, but …
What Slows (and Speeds) Skin Aging at the DNA Level
This study identifies 37 factors—from lifestyle choices to medications—correlated with slower or faster skin aging at the molecular level. The findings are a good starting point for testing whether any …
Quinoa skin cream shows molecular signs of reversing aging in human skin
This early-stage study shows that a quinoa product can alter skin proteins in ways that resemble younger skin, which is scientifically interesting. However, it's a small proof-of-concept that needs much …
Plant Extract Shows Promise for Slowing Aging in Model Organisms
This study shows promising laboratory results suggesting a plant extract can slow aging in model organisms by activating known longevity pathways. However, it's very early research: the findings are in …
Can metformin keep muscles and bones strong as we age?
This is promising early-stage evidence that metformin might help prevent aging-related weakness in middle age, but it's in mice. We need careful human studies before recommending it as an anti-aging …
How aging immune systems damage lungs—and what treatments might help
A well-written summary of how aging weakens lung immunity and what scientists are trying to fix it—but most treatments are still experimental, not proven to work in large patient groups. …
Genetic secrets of extreme old age discovered in Taiwan
This is solid population genetics work showing that some genes protect extreme longevity in Taiwanese people, but the practical impact is small—your lifestyle and heart health are still the main …
Keeping Cells Fit in Old Age by Rewiring a Key Metabolic Switch
A clever genetic fix lets yeast cells stay vigorous in old age by balancing competing metabolic needs, suggesting aging's decline in fitness isn't hardwired—but this remains a laboratory finding in …
Can MRI scans reveal who's aging faster? A new framework using AI and 70,000 scans
This is a promising early-stage study showing that AI can extract aging signals from MRI scans and link them to disease, but it's not yet ready to be used in …
Can ginseng compounds slow aging? A review of the science and future potential
This is a well-organized summary of why ginseng compounds *might* slow aging based on lab studies, but it doesn't prove they work in humans. It's a useful research roadmap, not …
New hydrogel with stem cell vesicles reverses aging damage in bone healing
This animal study shows a promising new technology combining stem cell signals and a sticky healing gel can improve bone repair in aging models—but results are early-stage and haven't yet …
How We're Moving From Understanding Aging to Actually Treating It
This is a progress report from leading aging researchers showing the field has moved from 'aging is inevitable' to 'aging is a treatable biological process'—a major shift in philosophy and …
Eating Only During an 8-Hour Window Extended Male Mouse Lifespan by 12%
This mouse study suggests time-restricted eating (eating within an 8-hour window) can improve health and may extend lifespan in males, but the lack of peer review, replication, and female lifespan …
How Metformin May Slow Aging: Mechanisms and Evidence
Metformin shows real promise as an anti-aging drug based on how it works and population-level health data, but we don't yet have the rigorous human trials needed to be sure …
Fixing worn telomeres restores heart function in heart failure
Researchers showed that sealing damaged chromosome caps in mouse hearts reverses heart failure through a specific molecular pathway. This is promising proof-of-concept, but replication and safety testing in humans would …
Why longevity treatments work differently for men and women
This paper identifies an important gap: anti-aging treatments affect men and women differently, but we don't fully understand why. Future research should explicitly test sex differences to develop better personalized …
Popular Senolytic Drugs Failed to Work in Rigorous Independent Testing
Drugs previously hyped as senolytic 'anti-aging' treatments didn't actually work when tested independently. This shows why we need rigorous confirmation before believing any longevity breakthrough.
Why Astronauts Are the Perfect Model for Understanding Aging
This is an intriguing idea that spaceflight research could help us understand and slow aging, but it's a proposal for future work, not proven science. Treat it as a conversation-starter …
Why lowering IGF-1 doesn't always extend lifespan—it depends on your mitochondria
This mouse study reveals that one of the most promising anti-aging strategies (lowering IGF-1) only works if your mitochondria are healthy—it's a reminder that aging is complicated and we may …
How Adrenaline-Like Signals in the Gut Could Slow Aging in Fruit Flies
Fruit fly studies suggest that carefully boosting adrenaline-like signals in the gut—not systemically—can extend life. This is a promising lead for drug development, but it's very early and human applicability …
