Medical Xpress / Exploiting a common weakness in enzymes could lead to a single vaccine against diarrhea-causing gut pathogens
The bacteria enterotoxigenic E. coli and Shigella together cause hundreds of millions of infections each year and are among the leading causes of diarrheal death, especially in children. Decades of vaccine development efforts ...
Medical Xpress / With neuronal data, AI models predict grammar, meaning and context of spoken sentences
By applying machine-learning models to single-cell brain recordings taken from humans in conversation, a research team identified both individual and collective neuronal activity that reflected key features of language. The ...
Medical Xpress / Study identifies a new cause of age-related inflammation, suggesting promising treatment pathway
A new study led by researchers at The University of Texas MD Anderson Cancer Center has uncovered a previously unknown connection between nucleic acid structures called R-loops and age-related inflammation—or inflammaging—that ...
Medical Xpress / How a flash of light could help the brain learn new skills
A new University of Otago—Ōtākou Whakaihu Waka-led study has put its own spin on Pavlov's dog experiment, shining a light on how our brain learns new things. The study, "The superior colliculus gates dopamine responses to ...
Medical Xpress / An experimental molecule 'reprograms' the brain's defenses against Alzheimer's disease
A team has identified an experimental molecule capable of "reprogramming" the brain's immune cells to restore part of their protective function against Alzheimer's disease. The study, published in the journal Cell Death and ...
Medical Xpress / Scientists uncover how physical activity may help protect older adults against cancer
Duke-NUS scientists have discovered that aging muscle may contribute to cancer growth by releasing fewer extracellular vesicles, tiny particles that cells use to communicate with one another. Their study also found that the ...
Medical Xpress / Birth control pills may increase binge eating, new study reveals
A new study from Michigan State University found increases in binge eating when taking hormone pills in the form of oral contraceptives—but not in all women. This is the first large-scale study of changes in binge-related ...
Medical Xpress / Vibrating pill could help predict relapse risk for anorexia nervosa patients
Anorexia nervosa is a psychiatric disorder characterized by persistent restriction of food intake, fear of gaining weight and distorted body image, often leading to significantly low body weight. Relapse rates for people ...
Medical Xpress / Everyday chemical exposures linked to preterm birth and lower birthweight
In one of the largest studies of chemical exposures during pregnancy to date, new research led by the UNC Gillings School of Global Public Health, Stanford University School of Medicine and Woods Institute for the Environment ...
Medical Xpress / Newborn neurons routinely break then repair DNA during brain cortex formation, study reveals
Newborn nerve cells must squeeze through crowded, narrow spaces—through dense tissue, past other cells, and between fibers—to reach the areas where they form neural circuits in the brain cortex. In a study published in Nature, ...
Medical Xpress / Fully open medical AI framework lets anyone audit how clinical LLMs are built
Medical large language models (LLMs) are increasingly being used in clinical settings. For example, AI is helping doctors in emergency rooms flag diagnoses or support decisions. The problem is that most of these systems are ...
Medical Xpress / Infant sleep movements reveal 60-minute cycles of inactivity that lengthen through first year
Infants' activity while sleeping is rhythmic, according to a new study from the University of Surrey. The findings provide crucial insight into sleep cycles of infants in the first year of life. In the largest study of its ...
