Summary: Researchers identified a crucial behavioral paradox in contemporary weight management: adults taking glucagon-like peptide-1 (GLP-1) receptor agonists show a measurable decline in daily physical activity, despite losing weight. Using passive wearable sensor data from the National Institutes of Health (NIH) All of Us Research Program, investigators combined Fitbit activity records with linked electronic health … Read more

Summary: Researchers have uncovered a striking biological convergence: obesity-related memory loss and natural age-related cognitive decline appear to share the same disruptive molecular pathway in the brain. Using advanced rodent models and CRISPR-based gene-editing techniques, the team led by Timothy Jarome at Virginia Tech identified a specific molecular mechanism—K63 polyubiquitination—as a shared driver of memory … Read more

Summary: A large-scale meta-analysis by the Biosocial research team provides the most comprehensive empirical evidence to date linking social inequality with accelerated biological aging. Reviewing 1,065 effect sizes from 140 independent studies and tracking 65,919 participants from birth to age 86, the study reveals a clear pattern: systemic poverty and racial discrimination leave chemical marks … Read more

Summary: A striking clinical case has led neuroscientists to reconsider how much latent cognitive function might remain in the aging brain. The report follows a Japanese‑American woman in her 80s with a decade of progressive Alzheimer’s disease who, after receiving a supervised dose of psilocybin‑containing mushrooms, experienced an unexpected and prolonged return of spontaneous speech, … Read more

Summary: Researchers have mapped a molecular chain reaction that converts the brain’s own immune response into a destructive process after a concussion. The work identifies a neuron-specific TLR4–MMP-9 pathway that rapidly degrades the extracellular matrix and produces chronic circuit noise, memory loss, and seizure susceptibility after mild-to-moderate traumatic brain injury (TBI). Using rat and mouse … Read more

Summary: Researchers have identified a concerning safety signal linking widely used glucagon-like peptide-1 (GLP-1) receptor agonists—semaglutide, tirzepatide and liraglutide—to a measurable rise in clinically significant hypotensive episodes. These episodes include severe dizziness, fainting and traumatic falls, particularly among older adults and people with Type 2 diabetes. Using electronic health records from more than 42,000 adults … Read more

Summary: A new study presents the first complete, circuit-wide map of how the brain predicts and cancels self-generated sensory inputs. The research shows a compact neural hub synchronizes sensory predictions with changing bodies, revealing principles that could illuminate human sensory processing disorders. Animals use an internal copy of motor commands—called corollary discharge—to distinguish self-generated sensations … Read more

Summary: Researchers have identified a previously hidden metabolic pathway that helps explain why advanced maternal age (AMA) reduces female fertility and lowers the success rates of assisted reproductive technologies (ART). Using non-targeted lipidomics and proteomics together with multi-omics sequencing (RNA-seq, Cut&Tag, ATAC-seq), the team found that embryos from older females show a pronounced decline in … Read more

Summary: A recent study overturns common intuition about how we notice emotional language, demonstrating that the brain can actively filter out negative spoken words before they become conscious. Bypassing typical visual masking methods, the research team developed an auditory paradigm using continuous streams of meaningless pseudowords with occasional real words to test how emotional valence … Read more

Summary: Researchers have revealed an important behavioral paradox in contemporary weight-management: adults taking glucagon-like peptide-1 (GLP-1) receptor agonist medications exhibit a measurable, clinically meaningful decline in daily physical activity despite weight loss. Using un-coerced, real-world wearable sensor data from the National Institutes of Health (NIH) All of Us Research Program, investigators combined Fitbit activity records … Read more
