Researchers used advanced imaging and mass spectrometry to map how insulin receptors behave in muscle cells, discovering they travel via two different cellular pathways—one involving caveolin and one involving clathrin. This fundamental understanding of insulin …
This review examines Akkermansia muciniphila, a beneficial gut bacterium that declines with age and is linked to inflammation and metabolic problems. While some studies show it strengthens the intestinal barrier and reduces aging-related decline, others …
Researchers created a computational model that simulates how fruit fly larvae move, navigate, and learn—combining physics-based locomotion with neural circuits and behavior. This tool could help neuroscientists test theories about how brains control behavior without …
Researchers discovered that a protein called LHX1 silences STING, a cellular alarm system that triggers senescence (aging) and tumor suppression in head and neck cancer cells. Disrupting LHX1 reactivates this alarm, causing cancer cells to …
Researchers trained artificial intelligence models to automatically identify different kidney cell structures using a simple imaging technique, without needing stains or labels. This tool could help scientists understand how kidneys age and develop better tests …
Researchers found that glycine supplementation extended lifespan in fruit flies and improved age-related damage in rats by activating a protein called Nmdmc that enhances mitochondrial energy production and DNA repair. The mechanism involves reshaping how …
Researchers created a mathematical model showing how two inhibitor proteins (Dickkopf) and Wnt signalling interact to form Hydra's body axis through mutual inhibition rather than the classical activator-inhibitor mechanism. This provides a mechanistic blueprint for …
Researchers used imaging in 285 macaques and postmortem human eyes to map how the retina thickens during development but thins with age—a pattern that could help us understand age-related vision loss. The findings suggest macaques …
Researchers experimentally warmed nests of wild great tits by 2°C during development and found the chicks showed accelerated telomere shortening—a cellular aging marker—despite normal growth. This suggests climate warming could speed up aging in birds, …
This narrative review examines whether three readily available blood markers—lymphopenia, neutrophilia, and the neutrophil-to-lymphocyte ratio (NLR)—can reliably indicate immune aging and predict severe COVID-19 outcomes in elderly patients. The authors conclude these markers consistently correlate …
Researchers found that a protein called TFAM, which manages mitochondria in regulatory T cells (immune cells that calm inflammation), is critical for preventing age-related systemic inflammation and physical decline. When mitochondrial function deteriorates in these …
This paper argues that 'identification'—feeling a sense of sameness with another person—is a fundamental mental process rooted in both psychology and brain biology, especially important when we're under stress or trauma. The authors propose that …
This is a ornithological ecology study about where Black Woodpeckers excavate cavities in French forests—it has no relevance to human aging, lifespan, or longevity research. The analysis examined landscape and forest composition factors across three …
Researchers found that a protein called TIMP2 is overproduced after acute kidney injury and actively drives the transition to chronic kidney disease by promoting cell aging and scarring. Deleting TIMP2 in kidney tubule cells in …
Researchers grew human pluripotent stem cells on circular patterns and watched them spontaneously organize into distinct midbrain and hindbrain regions—without being explicitly programmed to do so. This self-organizing system could help screen for birth defects …
