How We Score
How we vet the research — transparency first
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 However, it's unpublished and hasn't been tested in humans yet—promising but preliminary.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 …
Why a Specific Gene Receptor Controls Aging in Mice
This study shows a specific gene (FXR) is crucial for normal aging in mice, suggesting it could be a target for anti-aging drugs. However, this is early-stage research in animals; …
Can a longevity protein protect Parkinson's patients from memory loss?
A longevity protein shows promise in helping Parkinson's patients preserve cognitive function through mouse and genetic studies, but these findings need to be confirmed in human clinical trials before we …
Can a Heart Ultrasound Tell Your True Age?
This is an intriguing first step suggesting ultrasound plus AI could help identify who's aging faster in their heart and arteries. But it's not yet proven to predict future disease—we …
Two Repurposed Drugs Trigger Cellular Stress Responses That Extend Lifespan in Worms
This is a promising screening discovery suggesting two existing drugs might activate cellular defense pathways linked to aging. However, it's a first report in worms that needs independent replication and …
A Protein Called ATG-18 Extends Lifespan Without Needing Its Usual Autophagy Role
This is a solid mechanistic discovery in worms showing that a famous aging protein works differently than scientists thought—but we need follow-up studies in mammals to know if it matters …
How Intermittent Fasting Protects Brain DNA Through Metabolic Signaling
This mechanistic study in mice provides compelling evidence that intermittent fasting activates durable DNA repair and antioxidant programs in the brain through a metabolic-epigenetic pathway. However, it's a foundational animal …
How Jellyfish Sense Stress and Trigger Regeneration: A Protein Map
This paper uses advanced protein-mapping technology to describe how an immortal jellyfish switches from dormancy to regeneration, pinpointing three molecular 'hubs' that might control this decision. It's a solid first …
How IGF-1 Triggers Cellular Aging: A New Model for Targeted Rejuvenation
This review presents a clever new idea about how IGF-1 timing—not just amount—might drive aging, but it's a hypothesis, not proven fact. Until human trials test it, treat it as …
Why Healthspan Matters More Than Just Living Longer
This editorial makes a conceptual argument—not a research discovery—that longevity researchers have been asking the wrong primary question. Instead of just 'how long can we live?', we should ask 'how …
Making Epigenetic Age Clocks Work with DNA Sequencing Data
This preprint describes a useful technical solution for adapting aging clocks to work with modern DNA sequencing, but it's too early to rely on these findings. Wait for peer review …
HIV Drug Shows Promise for Slowing Biological Aging in Healthy Adults
An intriguing early-stage finding suggesting an existing HIV drug might slow biological aging markers in healthy people, but it's far too preliminary to act on—the study is small, uncontrolled, and …
