Researchers show red blood cells drive better glucose tolerance at high altitude

Chronic hypoxia improves glucose tolerance in mice through insulin-independent mechanisms, with red blood cells acting as a major systemic glucose sink. Increased erythrocyte production and altered glycolytic flux help reduce circulating glucose while supporting oxygen delivery to tissues.

New review explores whether berries can slow cognitive decline linked to obesity

This systematic review in Nutrients evaluates human studies investigating whether polyphenol-rich berry consumption can modulate obesity-related metabolic dysfunction and support cognitive performance, particularly in individuals at risk of mild cognitive impairment. Evidence suggests modest memory benefits and possible metabolic improvements, although biomarker findings and long-term clinical relevance remain uncertain.

Study identifies PPP2R5C blood marker that may detect Alzheimer’s disease earlier

Emerging evidence suggests reduced plasma PPP2R5C levels may serve as an early indicator of Alzheimer’s disease before overt clinical symptoms appear. The protein appears linked to tau regulation, autophagy pathways, and cognitive decline, supporting its potential diagnostic relevance.

Ion channel TRPV4 found to regulate relief after scratching an itch

When you scratch an itch, something tells your brain when to stop. That moment of relief, when scratching feels "enough," is not accidental.

Scientists reveal how the body senses cold and menthol

When you step outside on a winter morning or pop a mint into your mouth, a tiny molecular sensor in your body springs into action, alerting your brain to the sensation of cold.

Blood test models predict when Alzheimer’s symptoms may start years in advance

Researchers developed plasma p-tau217–based clock models that estimate when cognitively unimpaired individuals with Alzheimer’s pathology may develop symptomatic disease. The models predicted symptom onset within about three to four years and may help improve clinical trial selection while remaining unsuitable for individual clinical decisions at present.

Disordered lipid nanoparticles enhance RNA delivery efficiency

The tiny fatty capsules that delivered COVID-19 mRNA vaccines into billions of arms may work better when they're a little disorganized.

Tuberculosis bacteria stiffen cell membranes to evade immune destruction

Scientists have uncovered an elegant biophysical trick that tuberculosis-causing bacteria use to survive inside human cells, a discovery that could lead to new strategies for fighting one of the world's deadliest infectious diseases.

Study reveals unexpected role of TMC proteins in deafness

Proteins long known to be essential for hearing have been hiding a talent: they also act as gatekeepers that shuffle fatty molecules across cell membranes.

MRSA and E. coli detected weeks after Potomac sewage spill

Nearly a month after a wastewater pipe broke and spewed hundreds of millions of gallons of raw sewage into the Potomac River just north of Washington, D.C., the latest water testing results from the University of Maryland School of Public Health continue to show high levels of E. coli and S. aureus – commonly called staph, including antibiotic-resistant MRSA.

Grant funds research on prenatal massage for maternal mental health

The Massage Therapy Foundation (MTF) announces the award of a research grant to University of Denver, Denver, Colo. The grant will support a three-year study entitled, "Prenatal Massage: A Complementary Approach for Maternal Health and Mental Health," led by Primary Investigator Galena Rhoades, PhD.

Certain brain regions found to be more active in people with obsessive-compulsive disorder

A new study revealed that certain brain regions are more active in people with obsessive-compulsive disorder (OCD) during cognitively demanding tasks.

Misinformation and uncertainty drive misunderstanding of medical aid in dying

Public misunderstanding about medical aid in dying in the United States falls into two distinct categories – misinformation and uncertainty – and each is driven by different forces, according to Rutgers Health researchers.

Genetic differences may shape emotional reactions to art

Why do some people feel chills when listening to music, reading poetry, or viewing a powerful work of art, while others do not? New research by Giacomo Bignardi and his colleagues from Max Planck Institute for Psycholinguistics (MPI) published in PLOS Genetics reveals that part of the answer lies in our genes.
