Medical Xpress / Stopping fatal blood loss with clay
Traumatic injury is the third leading cause of death in the state of Texas, surpassing strokes, Alzheimer's disease and diabetes, according to the Centers for Disease Control and Prevention. A massive number of these deaths ...
Medical Xpress / Our brains may learn more from rare events than from repetition
More than a century ago, Pavlov trained his dog to associate the sound of a bell with food. Ever since, scientists have assumed the dog learned this through repetition. The more times the dog heard the bell and then got fed, ...
Medical Xpress / How dopamine-producing neurons arise in the developing brain
In a new study from Karolinska Institutet, published in Nature Neuroscience, researchers have identified the neurogenic progenitor that gives rise to dopaminergic neurons, the primary neurons affected in Parkinson's disease. ...
Medical Xpress / The neurobiology of why some brains cannot move on from loss
For most people, the intense ache that follows the death of a loved one eventually softens, and daily life resumes. But for some, the pain does not ease with time—a condition known as prolonged grief disorder (PGD). In ...
Medical Xpress / Pop-up-style 3D electrode array captures organoid-wide brain rhythms in real time
A team led by Northwestern University and Shirley Ryan AbilityLab scientists have developed a new technology that can eavesdrop on the hidden electrical dialogues unfolding inside miniature, lab-grown human brain-like tissues. ...
Medical Xpress / A genetic brake that forms our muscles: Variant linked to endurance may also raise odds of injury
In an international study, researchers at Lund University in Sweden have identified a gene variant that controls the body's capability to form new blood vessels in muscles—a mechanism that affects physical performance, ...
Medical Xpress / Ultra-endurance running may accelerate aging and breakdown of red blood cells
Extreme endurance running damages red blood cells in ways that may affect their ability to function properly, according to a recent study. Although the duration and long-term implications of the damage are unclear, the study ...
Medical Xpress / Debilitating tropical virus can spread in cool weather, posing a greater health risk than previously thought
Chikungunya virus, a debilitating tropical disease caused by infected mosquito bites, poses a greater health threat in Europe than previously thought because it can be spread when air temperatures are as low as 13°C. Researchers ...
Medical Xpress / Spiritual practices strongly associated with reduced risk for hazardous alcohol and drug use
Individuals who engaged in spirituality were significantly less likely to exhibit hazardous use of alcohol, tobacco, marijuana, and illicit drugs, according to a new meta-analysis led by researchers at Harvard T.H. Chan School ...
Medical Xpress / Cancer stress protein helps tumors hide from immune system
A protein made by stressed cancer cells helps lung and pancreatic tumors evade the immune system, a new study shows. Led by researchers from NYU Langone Health, the work found that new drugs designed to block the action of ...
Medical Xpress / Experimental vaccine protects against C. diff disease and recurrence
A novel vaccination approach developed by Vanderbilt Health researchers cleared the harmful gut bacterium Clostridioides difficile (C. diff) in an animal model of infection. An experimental vaccine administered to the mucosal ...
Medical Xpress / Mapping protein production in brain cells yields new insights for brain disease
The brain's ability to do everything from forming memories to coordinating movement relies on its cells producing the right proteins at the right time. But directly measuring this protein production, known as translation, ...
