Longevity & Aging

High Phosphate Diets Drive Hypertension by Hijacking Brain Growth Factor Signaling

Excess dietary phosphate raises FGF23, which crosses into the brain and triggers sympathetic overactivation and high blood pressure via FGFR4.

Cancer Research

New Enzyme Target USP20 Could Break Through Pancreatic Cancer Drug Resistance

USP20 drives immune exhaustion in pancreatic cancer by hijacking cholesterol and autophagy — and blocking it triples treatment response in preclinical models.

Cancer Research

Blocking a Key Enzyme Starves Pancreatic Cancer of Its Fuel

A lipid metabolism enzyme called SMPD1 anchors the deadliest cancer mutation to the cell membrane — and blocking it may finally crack KRAS.

Autoimmune & Arthritis

LEF1 Transcription Factor Identified as Master Regulator of T Cell Stemness in Chronic Disease

Researchers discover LEF1 marks true self-renewing T cells in autoimmunity and chronic infection, opening new therapeutic targets.

Harvard Team Maps 12,000 Viral Proteins to Reveal How Viruses Hijack Immunity

A massive viral gene library exposes hundreds of proteins that suppress immune detection — with major implications for infection, cancer, and aging.

Exercise & Fitness

Regular Exercise Reverses Half of Muscle's Molecular Aging Signatures

A multi-omic study finds trained older adults retain muscle molecular profiles resembling those of young adults, revealing exercise's deep anti-aging effects.

Nutrition & Diet

Protein Switch 'Mitch' Burns Fat and Blocks New Fat Cell Formation

Disabling the MTCH2 protein in human cells supercharges fat burning and halts new fat cell growth — a potential obesity breakthrough.

Premature Menopause Dramatically Raises Long-Term Heart Disease Risk

Women who experience menopause before 40 face significantly elevated cardiovascular risk — here's what clinicians need to know.

Heart Health

Your Circadian Rhythm Strength Predicts Heart Disease Death Risk

Wrist accelerometer data from 4,814 adults reveals circadian misalignment raises cardiovascular mortality risk by 68%.

Gut & Microbiome

Your Gut Microbiome Shapes How Your Brain Senses Your Body

New research reveals gut microbes actively regulate interoception — the brain's ability to sense internal body states — with major implications for health.

Metabolic Health

Eating 3 Hours Before Bed Improves Blood Pressure and Blood Sugar Overnight

A randomized trial shows that extending overnight fasting by 3 hours, timed to sleep, cuts nighttime heart rate and improves glucose control.

Supplements

PROMETHEUS Trial Tests Personalized Supplements and Lifestyle for Healthy Aging

An 8-week feasibility trial combines NMN, urolithin A, creatine, and exercise to target individual aging patterns.
