Medical Xpress / Innovative algorithm makes genomic surveillance faster and more affordable for global disease outbreaks
Genomic surveillance—the process of monitoring and sequencing pathogens—is one of the most important tools for detecting emerging viral threats. But global surveillance systems remain costly, unevenly distributed and often ...
Medical Xpress / Airway cells, not immune cells, trigger silicosis: New understanding of a deadly disease
Silicosis—a devastating, incurable lung disease caused by inhaling silica dust—is surging worldwide, fueled by a new wave of aggressive cases in young tradespeople working with engineered stone. Despite its growing impact, ...
Medical Xpress / Ultra-processed foods linked to higher levels of 'bad' fatty acids in blood, study suggests
Consumption of ultra-processed food (UPF) results in a distinct metabolic "signature" in the blood, associated with potentially adverse health conditions, suggests a new study by an international team of researchers. The ...
Medical Xpress / How skimping on sleep leads to weight gain
People who shortened their sleep by around 80 minutes a night for six weeks gained weight—1 pound on average—and were more sedentary, researchers at Columbia University Vagelos College of Physicians and Surgeons found.
Medical Xpress / Men living in different regions show marked differences in sperm quality despite similar lifestyles, novel study finds
A new study has found substantial regional differences in sperm quality, with men in the highest-performing region recording almost double the total motile sperm count of those in the lowest-performing region.
Medical Xpress / Air pollution may alter how sperm genes function, major fertility study finds
New research presented at the 42nd Annual Meeting of the European Society of Human Reproduction and Embryology (ESHRE) suggests that exposure to air pollution may affect genes associated with sperm development, raising new ...
Medical Xpress / Natural regulator may slow several cancers by shutting down fibroblasts, study finds
An international research team co-led by the Institute of Biomedicine and Biotechnology of Cantabria (IBBTEC-CSIC-University of Cantabria) and CIC bioGUNE, member of BRTA, has identified a novel molecular mechanism that helps ...
Medical Xpress / Just one exposure to cocaine alters mouse brain cells for 2 weeks, research reveals
Researchers studying the impact of cocaine in mice have found that just one exposure to the drug can create changes in brain cells that persist for at least two weeks. Their findings were presented at the Federation of European ...
Medical Xpress / How cells dodge death: Newly identified protein regulator could reshape cancer treatment
Our bodies are constantly deciding which cells should live and which should die through a process called apoptosis. This type of programmed cell death enables organisms to remove damaged or potentially dangerous cells in ...
Medical Xpress / Fibronectin pathway may drive Marfan aortic damage, opening new drug targets
A new study published in Nature Communications identifies a molecular signaling pathway that contributes to the development of life-threatening aortic aneurysms and dissections in Marfan syndrome, a genetic disorder affecting ...
Medical Xpress / Editing AI mistakes can cost doctors time when writing to patients
Errors and irrelevant details mean physicians may spend more time editing AI-drafted responses than it would take to write them, a large study of an online patient portal shows. Artificial intelligence is spreading rapidly ...
Medical Xpress / Researchers discover molecular 'switch' that simultaneously manages touch and pain
A research team led by Prof. Hyosang Lee of the Department of Brain Sciences at DGIST has identified TWIK-1, a type of potassium channel expressed in the spinal cord and peripheral sensory neurons of the somatosensory system, ...
