How We Score
How we vet the research — transparency first
Can blocking SIRT2 slow aging in the pancreas?
This lab study hints that blocking a protein called SIRT2 might slow aging damage in pancreas tissue, but it's very early-stage work in rats. We'd need much more research, including …
How Cellular Powerhouses Control Aging and Lifespan
This paper makes a compelling case that cellular organelles—like mitochondria—coordinate with each other to control aging, and that boosting this coordination could be key to living longer. However, it's a …
Can gene therapy slow aging? A review of current evidence and real challenges
Gene therapy shows promise in slowing aging in animals, but we're nowhere near proven human treatments. This review honestly maps the science and the real obstacles—immunogenicity, off-target effects, and regulatory …
How Liver Health Shapes Aging and Longevity
This paper proposes the liver as a master control for aging and surveys evidence that many proven life-extension methods work by protecting liver health. It's a valuable organizational framework for …
Blood as a window and tool for reversing aging: what recent research reveals
Blood composition reflects and drives aging. Young blood can partially reverse aging in animals, opening a new therapeutic avenue—but we're far from knowing if this works safely in humans or …
How Too Much Salt Ages Your Blood Vessels—and a Drug That Might Fix It
This mouse study suggests that eating too much salt prematurely ages blood vessel cells, and a drug that clears these aged cells can restore vessel function. While promising, human trials …
How mitochondrial hydrogen peroxide can either harm or help cells live longer
This yeast study shows that small amounts of cellular stress (from hydrogen peroxide) can actually make cells live longer, challenging the idea that all oxidative stress is bad. The findings …
Why Long-Living Animals Hold Clues to Human Aging
A thought-provoking argument that aging research should study cells' internal structures in long-lived animals rather than focusing only on genes. It's a good direction-setting idea, but there are no new …
How a cellular energy molecule could slow kidney damage from diabetes
This review identifies a promising mechanism (NAD+ and SIRT3) that protects kidney cells from diabetes damage in lab studies, but warns that no human clinical trials have yet proven it …
Rethinking Oxidative Stress and Aging: Why ROS Isn't Simply the Enemy
This review reframes aging as a failure of cellular quality-control systems rather than simple toxin buildup, suggesting future anti-aging therapies should repair broken machinery rather than just eliminate reactive molecules. …
How gut bacteria and brain signals control lifespan in worms
A clever study showing that worm brains can sense which bacteria they eat and adjust aging signals accordingly. The findings are intellectually interesting but remain in worms—don't expect human treatments …
How worm mitochondria adapt to stress and live longer
This review explains how worm cells survive stress by switching their energy systems and triggering protective responses—insights that may help understand aging but don't yet translate to human treatments. It's …
Remote control for genes: Using electromagnetic fields to turn aging genes on and off
This is impressive basic science that gives researchers a new remote-control tool for genes in living animals. It's not yet proven to extend lifespan or work in humans, but it …
Plant polysaccharide delays muscle aging in worms by activating a key longevity pathway
This worm study suggests a traditional herb may slow muscle aging by activating a fundamental aging pathway, but we cannot yet say if it works in humans. It's an interesting …
How Huntington's Disease Damages the Cell's Packaging System
This is early-stage lab research that reveals a new mechanism of Huntington's disease but needs peer review and confirmation in animal or human brain tissue before it changes treatment approaches. …
