Medical Xpress / Gut bacterium could be key to tackling obesity crisis
The internet, libraries and bookshops are full of plans and advice on how to lose weight, from fad diets to intense exercise routines. But there could be another route to keeping the pounds away, and that's with a gut bacterium ...
Medical Xpress / Neural 'barcodes': Intra-regional brain dynamics linked to person-specific characteristics
People can think, behave and function very differently. These observed differences are known to be the result of complex interactions between genetics, neurobiological processes and life experiences.
Medical Xpress / Unusual days signal rising migraine risk
Harvard Medical School researchers report that higher day-to-day "trigger surprisal" scores were associated with migraine attacks over the next 12 and 24 hours. In this cohort, higher surprisal scores aligned with greater ...
Medical Xpress / Changes in a single gene can cause mental illness, study reveals
Until now, researchers assumed that schizophrenia, anxiety disorders or depression arise from an interplay of many different factors, including genetic ones.
Medical Xpress / Big sex differences found in how diet and insulin rewire muscle for better blood sugar
New research found that restricting calories dramatically rewires proteins in rat skeletal muscle, causing molecular changes that boost insulin sensitivity—crucial for blood sugar control in older adults, say scientists ...
Medical Xpress / Hypertension affects the brain much earlier than expected, study suggests
Hypertension impairs blood vessels, neurons and white matter in the brain well before the condition causes a measurable rise in blood pressure, according to a new preclinical study from Weill Cornell Medicine investigators. ...
Medical Xpress / Inflammasome found to drive male-specific bone loss in gum disease
A study out of the University of North Carolina at Chapel Hill has unveiled new insights into the inflammatory processes behind periodontitis, a common and debilitating gum disease. Research conducted by UNC Adams School ...
Medical Xpress / Computational deep dive reveals hidden cancer drug targets and repurposing opportunities
One person's side effect could be another person's treatment if we expand our perspective on small molecule drug targets, according to a new study published November 5, 2025, in npj Precision Oncology.
Medical Xpress / How weakness in cell structure affects the host–microbiome relationship
Cells have an internal skeleton that maintains their structure and also drives their movement. Known as the cytoskeleton, this scaffold is composed of a network of dynamic filaments made of a protein called actin.
Medical Xpress / Reversing fibrosis: New research provides insight for novel therapies
Yale School of Medicine (YSM) researchers have made key breakthroughs in understanding how to treat fibrotic diseases such as scleroderma and graft-versus-host disease.
Medical Xpress / Q&A: Identifying new risk genes for schizophrenia
Schizophrenia, a psychiatric disorder that affects how a person feels, thinks, and behaves, affects roughly 1% of the population (approximately 3.5 million people in the U.S.) and is a leading cause of disability and death. ...
Medical Xpress / Traces of bacteria inside brain tumors may affect tumor behavior
Researchers at The University of Texas MD Anderson Cancer Center have uncovered unexpected traces of bacteria within brain tumors. This discovery offers new insights into the environment in which brain tumors grow and sets ...
