Biopsies disrupt the wound site and are too invasive for routine, repeated monitoring, and most medical imaging devices that could do the job are large, expensive, and booked up with more pressing diagnostics. Clinicians typically resort to visual inspection or quick measurements of the wound's size over time. https://medicalxpress.com/news/2026-03-ai-powered-imaging-tracks-wound.html Fri, 20 Mar 2026 15:20:05 EDT news693230641 An international research team has uncovered the next frontier in monitoring brain health, and the key is in technology that millions of people are already using every day—earbuds. The world-first study found that commercially available earbuds have the capability to detect and classify brain activity, simply by measuring subtle changes in users' hearing. The team used acoustic sensors in earphones to assess cognitive load—the mental effort that shapes learning, task performance and early cognitive decline. https://medicalxpress.com/news/2026-02-earbuds-brain-health.html Thu, 12 Feb 2026 09:43:13 EST news690110941 A preclinical study published in Nature has found evidence that the hippocampus, the brain region that stores memory, also reorganizes memories to anticipate future outcomes. https://medicalxpress.com/news/2026-01-hippocampus-memories-rewards.html Thu, 29 Jan 2026 15:04:55 EST news688921441 A fast-moving influenza strain nicknamed the "Super-K" flu is catching the attention of scientists and health authorities. https://medicalxpress.com/news/2026-01-super-flu.html Thu, 22 Jan 2026 10:15:57 EST news688299301 It was like a horror movie. The invisible polio virus would strike, leaving young children on crutches, in wheelchairs or in a dreaded "iron lung" ventilator. Each summer, the fear was so great that public pools and movie theaters closed. Parents canceled birthday parties, afraid their child might be the next victim. A U.S. president paralyzed by polio called for Americans to send dimes to the White House to support the nonprofit National Foundation for Infantile Paralysis, established by President Franklin D. Roosevelt and his lawyer, Basil O'Connor. Celebrities from Lucille Ball to Elvis were enlisted to promote this "March of Dimes," and mothers went door to door raising funds to conquer this dreaded disease. https://medicalxpress.com/news/2025-12-world-humanity-greatest-triumphs-polio.html Mon, 22 Dec 2025 22:40:01 EST news685623133 Inspired by owls and their amazing ability to find their prey by hearing alone, my team decided to test how good humans are at discerning sounds. https://medicalxpress.com/news/2025-11-auditory-illusions-ears-play.html Thu, 20 Nov 2025 11:47:03 EST news682861622 What was once tossed into compost bins could soon help grow stronger crops and even support human health, new research suggests. https://medicalxpress.com/news/2025-10-dont-toss-veggie-scraps-healthier.html Fri, 10 Oct 2025 12:20:04 EDT news679316629 Lyme disease is the most common vector-borne illness in the United States, a potentially disabling infection caused by bacteria transmitted through the bite of an infected tick to people and pets. https://medicalxpress.com/news/2025-09-lyme-disease-symptoms-treatment.html Mon, 22 Sep 2025 09:50:01 EDT news677752827 New research from University of Virginia psychologists has found that "epigenetic clocks"—tools scientists use to estimate a person's biological age—can predict cognitive decline.
