Medical Xpress / Mapping mutations at scale in a single gene reveals new neurodevelopmental condition
The ability of different genetic variants—changes to one or more building blocks of DNA—to cause disease, and to what extent, has historically been opaque. Geneticist and Crick group leader Greg Findlay has pioneered a new ...
Medical Xpress / Extra chromosomes may seed childhood leukemia years before disease, study suggests
B-cell acute lymphoblastic leukemia is the most common form of childhood cancer. In this type of cancer, which affects blood cells, one of the most common abnormalities is the presence of cells with an excess of chromosomes ...
Medical Xpress / Some common IBS treatments are linked to a higher risk of death, say study
A large, long-term study led by Cedars-Sinai Health Sciences University investigators suggests that some medications commonly prescribed to treat irritable bowel syndrome (IBS)—including antidepressants—may be associated ...
Medical Xpress / A wearable ring could help assess your cardiovascular health while you sleep
Consumer wearables have become everyday tools for monitoring sleep and physical activity. Researchers at the Centre for Sleep and Cognition at the NUS Yong Loo Lin School of Medicine (NUS Medicine) have now shown that their ...
Medical Xpress / Tau seeds spread through connected neurons in people with Alzheimer's disease, new research shows
Researchers have discovered the mechanism by which neurofibrillary tangles spread through the brain of Alzheimer's patients is via connected neurons, and these findings reveal a major disease etiology that could lead to new ...
Medical Xpress / A urine test that could change the course of bladder cancer care
Bladder cancer arises from the lining of the bladder, the organ that stores urine, and is one of the most common cancers in the United States. Most patients are diagnosed at an early stage called non-muscle invasive bladder ...
Medical Xpress / Long-term excess weight, not one-time BMI, can better predict cardiovascular risk
Obesity is a known risk factor for cardiovascular disease, but people's weights can shift over time, and little is known about the cumulative impact of excess weight. New research from investigators at Mass General Brigham ...
Medical Xpress / Lab-grown pineal gland organoids produce melatonin, offering a new sleep model
Organoids are miniature, simplified versions of an organ. Over the past two decades, scientists have developed them for the gut, lung, liver, mammary gland, brain, and more. Now, researchers at Yale School of Medicine (YSM) ...
Medical Xpress / Drones and AI take flight to combat mosquito-borne disease
As warming temperatures spread dengue to new regions, Stanford researchers are using AI-powered drones to hunt down hidden mosquito breeding sites. Anyone who has left water standing in a wading pool or empty flower pot knows ...
Medical Xpress / Cell-by-cell analysis offers clues to pregnancy risks
The biological connection between a pregnant woman and her developing baby has been mapped in unprecedented detail by UC San Francisco scientists, revealing new cell types and insights into conditions such as preeclampsia, ...
Medical Xpress / How the microprotein BRICK1 repairs and protects the heart after a heart attack
Every year, more than 200,000 people in Germany suffer a heart attack. This is caused by blocked coronary arteries. As a result, part of the heart muscle is no longer supplied with sufficient blood and oxygen; the tissue ...
Medical Xpress / Sequencing method exposes hidden gaps in immune signaling by tracking RNA and protein together
A new single-cell technology is giving scientists their clearest view yet of immune cell behavior—capturing not just genetic intent, but real-time activity. By measuring RNA and proteins simultaneously, it reveals cytokine ...
