Medical Xpress / Medical AI may look less biased on paper but not in practice, new study finds
Large language models (LLMs) are only as good as the data they learn from. If their training data contains social biases, the models may unintentionally repeat those biases in their responses. As their use increases with ...
Medical Xpress / Psychedelic drug screen in mice may overlook stress and brain changes
Over the past decades, some medical researchers and neuroscientists have been exploring the possible therapeutic effects of psychedelic compounds, such as lysergic acid diethylamide (LSD) and psilocybin. These are substances ...
Medical Xpress / Yeast dietary supplement may offer a safe nutritional strategy to boost cancer immunity
Researchers from Trinity College Dublin (TCD) and University College Dublin (UCD) have shown for the first time that a food supplement made from yeast helps the body make stronger immune cells that can fight cancer. The research ...
Medical Xpress / Brain imaging reveals how neural networks coordinate multiple streams at once
Working with concurrent electroencephalogram and functional magnetic resonance imaging technology at the Beckman Institute's Biomedical Imaging Center, postdoctoral researcher Suhnyoung Jun and her colleagues have investigated ...
Medical Xpress / New genetic switch could improve gene therapy for drug-resistant epilepsy
Epilepsy affects more than 50 million people worldwide, making it one of the most common neurological disorders. Although medication helps many patients achieve seizure control, approximately one-third continue to experience ...
Medical Xpress / Eye movements reveal personal 'fingerprints' as people explore unfamiliar scenes
Walk into a crowded coffee shop, and what catches your eye as you take in the scene could say as much about you as the spirals on your fingertips or the mutations in your DNA. Eye movements are so unique, in fact, that they ...
Medical Xpress / Low-oxygen treatment helped diseased mice live three times longer. Could humans benefit?
Oxygen isn't always a good thing. Of course, people—and most organisms—cannot live without it. But oxygen can also be quite toxic and lead to profound health consequences.
Medical Xpress / Hidden pathway drives COVID-19 infection, triggers damaging inflammation in the lungs
New research has uncovered a hidden pathway that allows COVID-19 to infect the immune system and trigger damaging inflammation in the lungs. The study by La Trobe University and WEHI researchers found SARS-CoV-2, the virus ...
Medical Xpress / Learning to identify new objects reshapes parts of the brain, research finds
The wiring and rewiring of the brain never ends. Neural pathways are constantly being reshaped as we interact with the world and learn new things. At York University and MIT's McGovern Institute, scientists are combining ...
Medical Xpress / Why some people are more bothered by low-frequency sounds
Some people are more sensitive to low-frequency noise, such as from ventilation systems, heat pumps, wind turbines and transformers. Why is that?
Medical Xpress / The smell of dark chocolate could make a leg workout easier, even on an empty stomach
Could the smell of chocolate wafting through the gym make strength training easier, or at least more pleasant? A new Frontiers in Physiology study found that sniffing dark chocolate with a high cocoa content decreased feelings ...
Medical Xpress / Mouse study identifies C1 neurons as a driver of prolonged fear and anxiety
Anxiety disorders affect more than 300 million people globally. Several brain regions have been linked to anxiety, but how these regions connect has been poorly understood. By exploring these connections, scientists at St. ...
