Medical Xpress / Genetic discovery may explain why pancreatic cancer is so difficult to treat
Pancreatic cancer can remain quiet for years, developing undetected before causing symptoms that lead to a diagnosis. Even after a surgeon removes a pancreas tumor, other cells often hide and erupt later. But University of ...
Medical Xpress / Disease-causing pathogen rewires gut metabolism to secure nutrients for growth, research shows
An intestinal pathogen reshapes the gut environment to fuel its own colonization and cause diseases, a multi-institutional team including researchers at Vanderbilt Health has discovered. The investigators show that enterotoxigenic ...
Medical Xpress / AI surpasses physicians on clinical reasoning tasks, raising the bar for more serious testing
In one of the largest studies to compare artificial intelligence and physicians on a wide array of clinical reasoning tasks including real emergency department data, a team of physicians and computer scientists at Harvard ...
Medical Xpress / No live animal testing needed: Lab-grown airway organoids reveal viral infection in wildlife species
Experimental infections, where a pathogen is introduced into the host body to see its effects in action, are considered the gold standard for assessing how vulnerable a host is, offering clear insights into how a pathogen ...
Medical Xpress / For 30 years, doctors chased the wrong immune culprit behind this rare inflammatory disease
Researchers at the Garvan Institute of Medical Research have uncovered a critical mechanism driving inflammation in mevalonate kinase deficiency (MKD), a rare but devastating autoinflammatory disorder. The study, published ...
Medical Xpress / Silencing stress signals could pave the way to a longer life
Silencing a major cellular stress signal could be the key to a longer life, according to new University of Sheffield research. While previous studies suggested that mild stress might help organisms live longer, new research ...
Medical Xpress / T cells secrete DNA to boost the immune system's cancer-fighting ability
Activated immune cells secrete tiny capsules bearing DNA that can enter other immune and tumor cells to stimulate the body's defense systems, according to a study led by investigators at Weill Cornell Medicine. The discovery ...
Medical Xpress / Glucose levels appear to guide when brain cells divide or form myelin
Researchers at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) have uncovered a surprising link between low brain sugar levels and the development of myelin—the protective coating that allows ...
Medical Xpress / Communication from the CDC fuels skepticism about vaccines and science, research suggests
The scientific consensus is that vaccinations are neither causally nor statistically linked to autism. The US health authority CDC changed its official communication on this matter and instead emphasized a connection could ...
Medical Xpress / Restoring protein recycling helps exhausted T cells fight tumors again
T cells are crucial components of our immune system, serving as critical protectors against infection and disease. But there are limits to their defensive capabilities. T cells are not inexhaustible protectors. Often, when ...
Medical Xpress / Severe narcolepsy found to damage a second brain region
For nearly 25 years, scientists believed they knew what caused the most severe form of narcolepsy. A new UCLA Health study now suggests they were only half correct. In a study published in Nature Communications, UCLA Health ...
Medical Xpress / Team targets the spinal cord to solve paralysis' most overlooked problem
Approximately 308,000 people in the United States live with spinal cord injury. Nearly all lose bladder control. And yet the vast majority of research and engineering attention in neurotech has poured into motor restoration—making ...
