Medical Xpress / Study pinpoints rare graft neurons that reconnect spinal walking circuits after injury
A rare group of neurons can reconnect broken spinal circuits and trigger leg muscle activity after spinal cord injury—a discovery that could help refine future stem-cell therapies for paralysis. The findings, published in ...
Medical Xpress / Light impacts how the brain perceives and remembers threats, study suggests
Northwestern Medicine scientists have discovered that light plays a key role in how animals perceive environmental threats, findings that have the potential to improve the understanding of risk avoidance behaviors and related ...
Medical Xpress / Common disinfectant chemicals far more toxic when inhaled, study finds
Breathing in common disinfectant chemicals known as quaternary ammonium compounds, or QACs, may be far more harmful than swallowing them, according to a mouse study led by researchers at the University of California, Davis. ...
Medical Xpress / An avatar to study pediatric brain cancer may soon be a reality
Biopsy-derived organoids, accurate models of disease, are used to search for new drugs. Now, results obtained by a study led by the University of Trento in collaboration with Bambino Gesù Children's Hospital in Rome may pave ...
Medical Xpress / Why feeling alone may matter more than being alone
Loneliness is often described as a simple absence—of people, of connection, of companionship. But two new studies suggest it may be something more complex, and more consequential: not just how socially connected people are, ...
Medical Xpress / A long-term and scalable system to record from neural organoids
Neural organoids have been heralded as having huge potential for advancing our knowledge of the brain in several fields. These include exploring the responses of brain tissue to drugs, investigating the effect of specific ...
Medical Xpress / DASH diet grocery program delivers blood pressure and cholesterol benefits
Black adults with high blood pressure who received dietitian counseling and home deliveries of groceries aligned with the DASH diet—meaning high in fruits, vegetables, whole grains, low-fat dairy, nuts, seeds, legumes and ...
Medical Xpress / Discovery of noma-linked bacteria opens path to early diagnosis and prevention
Researchers at Liverpool School of Tropical Medicine (LSTM) have identified a bacterium strongly associated with noma disease, marking a major step toward earlier diagnosis and more effective treatment. In a new study published ...
Medical Xpress / 20,000 lab-grown human retinas reveal how cone photoreceptor cells resist degeneration
Scientists led by Botond Roska at the Institute of Molecular and Clinical Ophthalmology Basel (IOB) and collaborators have identified genetic pathways and compounds capable of protecting cone photoreceptors from the degeneration ...
Medical Xpress / Shedding light on the brain: New method controls neural pathway communication
Understanding how the brain works requires more than studying single regions in isolation. The cerebral cortex depends on long-distance connections that link specialized areas into coordinated networks. But scientists have ...
Medical Xpress / Bile acid and steroid signatures tied to extreme longevity
Centenarians often live to 100+ due to a combination of protective genetic factors, which account for up to 50%, and healthy lifestyles, such as plant-forward diets, regular, natural movement and strong social connections. ...
Medical Xpress / For severe babesiosis, red blood cell exchange is associated with markedly improved outcomes
A new study led by investigators from Mass General Brigham and Yale School of Public Health reveals that red blood cell exchange transfusion (ET) may provide critical benefits for patients hospitalized with severe babesiosis. ...
