Metformin demonstrates a previously unrecognized mechanism called the 'intestinal glucotonic effect,' where reactive oxygen species upregulate GLUT1…
Understanding how our genomes accumulate variations over time could unlock new approaches to predicting and preventing age-related diseases. The discovery…
Cell biologists have long struggled to observe kinase enzymes in action within living cells, despite these molecular switches controlling virtually every…
Understanding how reproductive cells develop could unlock new approaches to fertility preservation and age-related reproductive decline. The discovery of how…
The shifting landscape of pediatric mortality reveals profound changes in how American children face health risks, with implications extending far beyond…
Age-related muscle weakness may stem from a metabolic breakdown at the cellular level that prevents muscle stem cells from producing the fats they need to…
Rapamycin, originally developed as an immunosuppressant, has emerged as the most consistently effective anti-aging compound across multiple species by…
DNA polymerase kappa (POLK) progressively relocates from the nucleus to the cytoplasm in aging mouse neurons, with this redistribution serving as a predictor…
The genetic lottery of exceptional longevity may hinge on a single DNA variant's ability to transform how brain cells handle damage accumulation. While APOE2…
Deliberately breaking cellular machinery might seem counterintuitive for promoting longevity, yet this counterintuitive finding reveals how controlled…
Developmental knockdown of neuronal Raptor (mTORC1 component) reduced embryonic survival but didn't impact adult mortality, while neuronal mTOR knockdown…
Researchers discovered that intervertebral discs age remarkably slowly due to a unique cellular mechanism: they degrade hypoxia-inducible factor-1α (HIF-1α)…
Understanding how consciousness emerges from brain activity has profound implications for treating disorders of awareness, optimizing anesthesia protocols…
The persistence of Helicobacter pylori infections despite decades of treatment protocols signals a critical shift in how clinicians must approach this…
Researchers developed mAge, a biological aging framework that integrates plasma proteomics with wearable device data to predict biological age with…
Rapalink-1, a dual mTOR inhibitor, significantly reduced cellular senescence markers including SA-β-gal positivity, DNA damage (γ-H2AX and 8-OHDG), and…
Urolithin A, produced when gut bacteria metabolize ellagitannins from pomegranates and berries, activates key longevity pathways including AMPK and sirtuins…
Heart valve procedures are advancing beyond traditional open-heart surgery, potentially offering safer options for patients with severe tricuspid…
The accelerating global burden of age-related diseases demands evidence-based interventions that address fundamental aging mechanisms rather than isolated…
Natural selection weakens progressively throughout adulthood, creating a 'selection shadow' where mutations that cause harm only in later life accumulate…
