Gut Enzyme ST8Sia6 Acts as a Molecular Brake on Intestinal Inflammation

Mice lacking the sialyltransferase ST8Sia6 develop spontaneous small bowel immune activation and heightened colitis susceptibility, revealing a new glycosylation-based immune checkpoint.

Cancer Research

Scientists Crack Why Bird Flu Attacks Cow Udders Instead of Lungs

University of Pittsburgh researchers discovered H5N1 targets mammary tissue in dairy cows due to concentrated glycan receptors — a finding that could predict future outbreaks.

Cancer Research

Tiny Mutation in Bat Viruses Could Threaten Human Health

A small genetic change in bat viruses may enable them to infect humans.

Nutrition & Diet

Fructose Fails to Suppress Hunger Like Glucose Does in the Brain

New research reveals fructose and glucose trigger completely different hunger signals in the brain, even though they have the same calories.

Regenerative Medicine

Brensocatib Approval Opens New Era for Bronchiectasis Treatment

With brensocatib now approved, researchers are mapping the next wave of therapies for this chronic, underserved lung disease.

Hormones

SIRT3 Blocks AGE-Driven Ovarian Aging by Boosting Mitophagy in Granulosa Cells

New research shows SIRT3 overexpression reverses AGE-induced senescence in human granulosa cells by restoring mitophagy and hormone output.

Ovarian Aging Decoded: Pathways, Damage Mechanisms, and Emerging Therapies

A comprehensive review maps the molecular drivers of ovarian aging and surveys emerging interventions that may delay or reverse reproductive decline in women.

Regenerative Medicine

Stem Cell Exosomes Deliver miRNA to Reverse Androgenetic Hair Loss

Human umbilical cord stem cell exosomes carrying Let-7 microRNAs restored hair growth in mice and increased hair density in a clinical trial.

Gut & Microbiome

How to Do Gut Microbiome Aging Research Right — A Rigorous New Framework

A new review identifies five critical methodological pitfalls undermining microbiome-aging studies and offers a practical checklist to fix them.

Nutrition & Diet

Fast Food Diet Doubles Depression and Anxiety Risk in Large Cohort Study

Nearly 7,000 adults followed over time: those eating the most fast food and sugar faced double the risk of depression and anxiety.

Brain Health

AI Reads Brain MRI to Diagnose and Stage Parkinson's With High Accuracy

An interpretable machine learning model using MRI brain texture features diagnosed and staged Parkinson's disease with up to 90% accuracy across multiple centers.

Exercise & Fitness

10 Months of Exercise Cuts Ketone Levels 31% in Young Girls

A randomized trial finds regular aerobic exercise significantly lowers circulating ketone bodies in children, signaling improved mitochondrial function.

Autoimmune & Arthritis

Lifestyle Habits That Slow Immune Aging and Tame Chronic Inflammation

A new review reveals how diet, exercise, and stress reduction can measurably reverse key markers of immune aging and inflammaging.

Review

Metabolic Health

GLP-1 and SGLT-2 Drug Combo Hits Glucose Targets in 42% of Type 2 Diabetics

A real-world study of 549 patients finds that combining GLP-1 receptor agonists with SGLT-2 inhibitors meaningfully improves glucose control — and baseline HbA1c predicts who benefits most.

Sleep & Recovery

GLP-1 Drugs Cut Stroke Risk by 25% and Death by 62% in Sleep Apnea Patients

A massive real-world study of 877,000 OSA patients finds GLP-1 receptor agonists dramatically reduce strokes, hospitalizations, and mortality.

Heart Health

Dual-Action Nanoparticles Target Atherosclerosis by Fixing Autophagy and Clearing Inflammatory DNA

A new nanoparticle system delivers rapamycin and a DNA scavenger directly to arterial plaques, cutting inflammation and improving plaque stability in mice.

Sleep & Recovery

Screen Time Consistently Disrupts Sleep in Kids and Teens, Umbrella Review Confirms

A sweeping review of 84 studies finds screen time broadly harms children's sleep, though evidence quality remains a major concern.
