How We Score
How we vet the research — transparency first
Do diabetes drugs work differently in women vs men? A massive real-world study says yes
This large study found that women and men may need different diabetes drugs due to different side-effect risks, but these differences haven't been tested in formal clinical trials yet and …
Can AI Systems Understand Aging? A New Test for Foundation Models
This is a useful tool for checking whether AI systems can actually understand aging research, but it's brand new and hasn't been verified by independent scientists yet. Don't make major …
A plant compound slowed aging in worms and mice by tweaking metabolism
This is early-stage laboratory work showing a plant compound may slow aging by targeting a metabolism pathway. It's interesting science, but don't expect anti-aging supplements based on this plant to …
Boosting a Key Cellular Energy Molecule Extends Lifespan and Fights Alzheimer's in Flies
This is promising but preliminary fruit-fly research showing that boosting a specific energy molecule in mitochondria extends lifespan and fights Alzheimer's symptoms. Before considering this evidence for human treatments, we …
Why Age Spots Show Signs of Broken Epigenetic Control
This study identifies a plausible molecular mechanism for age spots—loss of epigenetic control—but it shows correlation, not cause-and-effect. It's an important descriptive finding that opens doors for future research, not …
How Fruit Flies Switch Between Fat and Carb Storage When Deprived of Dietary Fat
This fruit fly study reveals how bodies can switch from storing fat to storing carbs when fat-making is blocked, with trade-offs between normal development and reduced lifespan. It's an early-stage …
Why autophagy's effect on aging varies wildly—and why that matters
This preprint suggests autophagy's role in aging is far messier than textbooks claim—its effects depend heavily on temperature, genetics, and lab conditions. Until peer-reviewed, treat as a cautionary observation rather …
How a missing immune protein ages the placenta and causes miscarriage
This study reveals that missing IL33 protein causes the placenta to age prematurely, leading to miscarriage in mice. Existing drugs that slow cellular aging reversed this damage, offering hope—but human …
What really slows aging in long-lived worms? New theory reshapes our understanding
This paper suggests scientists have been misreading a key equation about aging for 150+ years—not the math itself, but what it actually tells us about health. If proven correct in …
A drug combo slows spine disc aging in mice with genetic predisposition
A promising preclinical finding that clearing senescent cells may slow spine degeneration—but much more work is needed before we know if this helps people with back pain.
How aging cells slow wound healing in diabetes—and new treatments that might help
This paper makes a thoughtful case that clearing out aged, dysfunctional cells could improve diabetic wound healing. However, it's a summary of existing research, not a breakthrough—actual human studies are …
How Lysosomes Control Aging: New Pathways to Longer, Healthier Lives
This review presents interesting new ideas about how cells' recycling systems control aging, positioning lysosomes as potential therapeutic targets. However, these are early-stage discoveries in cells and animals—we don't yet …
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 …
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. …
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 …
