Medical Xpress / New video dataset captures human dynamics of care, advancing AI for health care
Researchers at the University of Pennsylvania have launched Observer, the first multimodal medical dataset to capture anonymized, real-time interactions between patients and clinicians. Much like the medical drama The Pitt, ...
Medical Xpress / Higher maternal vitamin D during pregnancy tied to less childhood tooth decay
Zhejiang University School of Medicine investigators reported that higher maternal plasma 25-hydroxyvitamin D levels across pregnancy aligned with lower odds of early childhood caries in children.
Medical Xpress / Small RNA molecule found to control cholesterol and heart disease risk
A team of researchers led by University of California, Riverside biomedical scientists has identified a small, previously overlooked small RNA molecule that plays a major role in controlling the body's cholesterol production ...
Medical Xpress / Gut bacteria from amphibians and reptiles achieve complete tumor elimination in preclinical model
A research team of Prof. Eijiro Miyako at the Japan Advanced Institute of Science and Technology (JAIST) has discovered that the bacterium Ewingella americana, isolated from the intestines of Japanese tree frogs (Dryophytes ...
Medical Xpress / When neural spikes break time's symmetry: Linking the information-theoretic cost of brain activity to behavior
What if we could peer into the brain and watch how it organizes information as we act, perceive, or make decisions? A new study has introduced a method that does exactly this—not just by looking at fine-grained neuronal ...
Medical Xpress / Neurons use physical signals, not electricity, to stabilize communication
Every movement you make and every memory you form depends on precise communication between neurons. When that communication is disrupted, the brain must rapidly rebalance its internal signaling to keep circuits functioning ...
Medical Xpress / Decoding long COVID: Investigators reveal why the body keeps fighting the war
A new study from investigators at Beth Israel Deaconess Medical Center (BIDMC) sheds light on why some people never fully recover from COVID-19.
Medical Xpress / A fatal mix-up: How certain gut bacteria drive multiple sclerosis
If gut bacteria are too similar to the protective layer of nerves, they can misdirect the immune system and cause it to attack its own nervous system. This mechanism can accelerate the progression of multiple sclerosis, as ...
Medical Xpress / AI helps explain how covert attention works and uncovers new neuron types
Shifting focus on a visual scene without moving our eyes—think driving, or reading a room for the reaction to your joke—is a behavior known as covert attention. We do it all the time, but little is known about its neurophysiological ...
Medical Xpress / AI-engineered nasal spray antiviral platform developed to block flu and COVID-19
Respiratory viruses that have diverse strains and mutate rapidly, such as influenza and COVID-19, are difficult to block perfectly with vaccines alone. To solve this problem, KAIST's research team has successfully developed ...
Medical Xpress / Fertility gene helps glioblastoma tumors survive chemotherapy and return after treatment, researchers discover
Research by University of Sydney scientists has uncovered a mechanism that may explain why glioblastoma returns after treatment, offering new clues for future therapies which they will now investigate as part of an Australian ...
Medical Xpress / New AI tool identifies not just genetic mutations, but the diseases they may cause
Scientists at the Icahn School of Medicine at Mount Sinai have developed a novel artificial intelligence tool that not only identifies disease-causing genetic mutations but also predicts the type of disease those mutations ...
