How We Score
How we vet the research — transparency first
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 …
Does Body Fat Speed Up Aging? Testing Epigenetic Clocks in Young Filipinos
This early-stage study suggests body fat and accelerated cellular aging are linked in young Filipinos using a new combined measurement approach—but it's not yet published and needs independent confirmation before …
How Calorie Restriction Quiets Immune Attacks on Aging Pancreas Cells
This early-stage research suggests pancreas inflammation in aging drives diabetes, and calorie restriction can quiet it in mice. However, it's unpublished and hasn't been tested in humans yet—promising but preliminary.
How cells switch off a protective protein under low oxygen to extend life
This is solid fundamental research showing that cells have a previously unknown molecular 'switch' that turns off protective proteins when oxygen is low, enabling stress adaptation. While promising for understanding …
Combining Skin Treatments Inside and Out to Slow Aging
This paper makes an intellectually appealing case for combining skin treatments inside and out, but it's a literature survey, not a proof. The individual ingredients may help with aging, but …
Can the smell of toasted bread slow aging? C. elegans study suggests yes
A worm study found that smelling roasted-food aromas activated anti-aging genes and extended lifespan—intriguing for neurobiology, but don't expect this to explain human longevity until someone tests it in mammals …
How cells sort out faulty mitochondrial DNA to stay healthy and live longer
This paper explains an elegant cellular system for removing bad mitochondrial DNA copies, linking this mechanism to aging and disease. It's a thought-provoking synthesis, but doesn't yet provide proof that …
Cutting dietary valine extends male mouse lifespan by 23%
This mouse study suggests restricting one dietary amino acid (valine) might slow aging, but it's preliminary work that hasn't been peer-reviewed yet. Even if confirmed, we don't know if the …
Five new plant alkaloids extend lifespan in worms by up to 9%
This paper identifies five new plant chemicals that extended worm lifespan, which is scientifically interesting but very preliminary—similar findings in worms almost never translate to humans, so don't expect these …
