Obesity and older age are strongly associated with low-grade inflammation in the body, a condition that appears closely linked to cognitive decline and dementia.

Cornell researchers have discovered a new way cells regulate how they respond to stress, identifying an interaction between two proteins that helps keep a critical cellular recycling system in balance.

Chimeric antigen receptor (CAR) T cell therapy, a type of immunotherapy that leverages the immune system to combat diseases, is a powerful treatment option for certain cancers.

Breakthrough research from the University of Cincinnati College of Medicine is revealing how immune cells in the adult brain can regulate the generation of new neurons.

To think, feel, talk and move, neurons send messages through electrical signals in the brain and spinal cord.

Most registered nurses who recently left hospital employment are motivated to return to health care work-and safe nurse staffing levels is the top factor that would bring them back, according to new research from the University of Pennsylvania School of Nursing's Center for Health Outcomes and Policy Research (CHOPR).

A study conducted in Brazil by researchers at the Federal University of São Paulo (UNIFESP) and the ABC Medical School (FMABC) warns that the prolonged use of proton pump inhibitors (PPIs) can impair nutrient absorption.

The viewpoint reviews conflicting evidence on alcohol consumption, highlighting discrepancies between observational studies, genetic analyses, and public health guidance. It concludes that large randomized trials comparing alcohol moderation versus cessation are needed to clarify long-term health effects.

The legalization of cannabis and the start of retail sales of the drug in the US are linked to both a rise in its recreational use and concurrent use of tobacco, as well as a fall in sole tobacco use, finds an analysis of health behavioral data, published online in the journal Tobacco Control.

Tirzepatide significantly improved cardiometabolic risk markers in adults with obesity and moderate to severe obstructive sleep apnea in the SURMOUNT-OSA phase 3 trials. Mediation analyses suggest both weight loss and reduced sleep-disordered breathing contributed to improvements in inflammation, insulin resistance, lipids, and blood pressure.

A long-standing Medicare policy meant to manage rehabilitation services in nursing homes may keep older Americans in hospitals longer than necessary without improving patient health or saving Medicare money, new research finds.

A new study from McMaster University involving 2.8 million children around the world has revealed the most important early-life factors that influence whether a child becomes allergic to food.

Pancreatic cancer has a lot of nerve. Notoriously tricky to detect, the disease also often resists traditional therapy. So, researchers are urgently looking for new ways to disrupt tumor formation.

A new randomized controlled study funded by the Crohn's & Colitis Foundation found that time-restricted feeding-a form of intermittent fasting-significantly reduced symptomatic disease activity and systematic inflammation in adults with Crohn's disease and overweight or obesity.

A significant discovery by Case Western Reserve University researchers could change how doctors treat two of the most devastating neurodegenerative diseases.

New research in the February 2026 issue of JNCCN-Journal of the National Comprehensive Cancer Network found that incorporating information from prostate-specific membrane antigen (PSMA) PET/CT scans may be able to predict progression-free survival (PFS) and guide treatment planning in patients with rising prostate-specific antigen (PSA) levels following removal of the prostate.

Atherosclerosis underlies most heart attacks and strokes and is now recognized as a chronic inflammatory disease rather than a simple disorder of cholesterol deposition.

​Legalizing cannabis for both medical and recreational use may lead to a decline in daily opioid use among people who inject drugs in the United States, according to a new study led by a Boston University School of Public Health researcher (BUSPH).

Adults age 65 and older who completed five to six weeks of cognitive speed training - in this case, speed of processing training, which helps people quickly find visual information on a computer screen and handle increasingly complex tasks in a shorter time period - and who had follow-up sessions about one to three years later were less likely to be diagnosed with dementia, including Alzheimer's disease, up to two decades later, according to new findings published today in Alzheimer's & Dementia: Translational Research and Clinical Interventions.

After serious injuries, burns, fractures, or major surgeries, the body normally repairs damaged tissues and restores movement.
