The gut and brain are in constant conversation through a powerful biochemical signaling pathway. This two-way connection allows them to exchange signals that influence everything from digestion to emotional health, and studies suggest even the fate of neurodegenerative diseases.

The Inflation Reduction Act's attempt to improve insulin costs for Medicare beneficiaries—by capping out-of-pocket costs at $35—was associated with lower out-of-pocket costs and increased insulin use, but only for a small portion of U.S. patients, according to a new study published in JAMA.

People prescribed GLP-1 medications are more likely to start and stop than most people assume, according to a study presented at ENDO 2026, the Endocrine Society's annual meeting in Chicago.

The first real-world study of the FDA-approved nonhormone treatment fezolinetant found the menopausal medication improved hot flashes, depression and anxiety in women, according to industry-sponsored research presented at ENDO 2026, the Endocrine Society's annual meeting in Chicago.

The gut does much more than just digest food. Researchers at the University of Basel have discovered a surprising link between gut function, feeding and sleep in fruit flies. Their study adds to growing evidence that the gut communicates with the brain and can influence behavior.

It's not unusual to see a few brave souls wrapped in gloves and balaclavas jogging along the Charles or through Cambridge Common in the snow. But for most of us, running outdoors is a fair-weather sport.

A Harvard Chan/de Beaumont national poll of 2,205 U.S. adults found CDC trust dropped to 50% one year into new federal public health leadership, while state and local health agencies remained more trusted.

A Nature Metabolism study identifies brain hyperglycosylation as a metabolic driver of Alzheimer’s disease, with increased N-glycan biosynthesis seen in human AD tissue and mouse models. Reducing glycosylation improved memory in AD mice, while glucosamine worsened memory deficits in 5xFAD mice and was associated with poorer outcomes in dementia patients.

A 14-day open-label pilot study in 63 healthy adults found that short-chain oat fiber was well tolerated at doses up to 20 g/day and was associated with improved gastrointestinal symptom scores.

Women on menopausal hormonal therapy face a decreased risk of low bone mineral density compared to those not using it, according to a study being presented Sunday at ENDO 2026, the Endocrine Society's annual meeting in Chicago, Ill.
