Medical Xpress / A single genetic mutation may have made humans more vulnerable to cancer than chimpanzees
New research from UC Davis Comprehensive Cancer Center has uncovered an evolutionary change that may explain why certain immune cells in humans are less effective at fighting solid tumors compared to non-human primates. This ...
Medical Xpress / COVID data transformed disease projection models—researchers explain what's next
Scientists sometimes compare predicting the course of epidemics to forecasting the weather. But there's a major difference—the impact of human behavior—says Alessandro Vespignani, director of Northeastern University's ...
Medical Xpress / Gene for enzyme in saliva associated with type 2 diabetes
Nutrition scientists have been working to understand the relationship between type 2 diabetes and genes that express a salivary enzyme that breaks down starch, but many conflicting studies have led to few clear answers.
Medical Xpress / Clinical test predicts best rheumatoid arthritis treatment on first try
1 in 100 people in Britain today live with rheumatoid arthritis (RA). Unlike osteoarthritis (OA), RA is caused not by wear and tear but by the body's immune system attacking its own joints. RA can strike quickly at any age—but ...
Medical Xpress / Key group of cerebral amygdala neurons identified in anxiety and social disorders
A research team has discovered that a specific group of neurons in the amygdala, a brain region involved in emotion regulation, plays a key role in the emergence of conditions such as anxiety, depression, and altered social ...
Medical Xpress / AI and biophysics unite to forecast high-risk viral variants before outbreaks
When the first reports of a new COVID-19 variant emerge, scientists worldwide scramble to answer a critical question: Will this new strain be more contagious or more severe than its predecessors? By the time answers arrive, ...
Medical Xpress / T cells take aim at Chikungunya virus
A new study, published recently in Nature Communications, offers the first-ever map of which parts of the Chikungunya virus trigger the strongest response from the body's T cells.
Medical Xpress / Antibody sIgM emerges as a key guardian of gut health and metabolism
A pioneering new study published in Nature Microbiology, led by J. Oriol Sunyer, professor of immunology and pathobiology at the School of Veterinary Medicine, and a team of researchers at Penn Vet and the University of New ...
Medical Xpress / Babies' poor vision may help organize visual brain pathways
Incoming information from the retina is channeled into two pathways in the brain's visual system: one that's responsible for processing color and fine spatial detail, and another that's involved in spatial localization and ...
Medical Xpress / Researchers reveal key differences in STING inhibition between humans and mice
Researchers have long focused on the STING (Stimulator of Interferon Genes) pathway as a way to harness the immune system's natural defenses against cancer. This pathway, which plays a key role in helping the body defend ...
Medical Xpress / Scientifically grounded recommendations for stretching published for the first time
For the first time, an international research team has developed concrete, evidence-based stretching recommendations for practical use. The team was led by Prof. Dr. Dr. Jan Wilke of the University of Bayreuth. Their recommendations, ...
Medical Xpress / Death of a partner and financial stress linked to increased risk of Alzheimer's disease, differences in brain structure
Stressful life events can negatively impact brain health. Specifically, grief over the loss of a partner has been linked to alterations in biological processes associated with Alzheimer's disease, while unemployment and financial ...
