A recent study in JAMA Network Open has found that between January and March 2025, America's Poison Centers reported a 38.7% increase in vitamin A exposures during the measles outbreak across many states. https://medicalxpress.com/news/2026-06-vitamin-poisonings-rose-measles-misinformation.html Fri, 05 Jun 2026 08:00:01 EDT news699808455 In response to stress or damage, cells undergo senescence and stop dividing. However, if senescent cells accumulate in tissues over the long term, chronic inflammation occurs and the risk of cancer increases. Researchers at the German Cancer Research Center (DKFZ) have now discovered a previously unknown mechanism by which senescent cells protect themselves from oxidative stress and a specific form of cell death known as ferroptosis. https://medicalxpress.com/news/2026-06-senescent-cells-dodge-cell-death.html Wed, 03 Jun 2026 18:00:01 EDT news699720345 A new UC San Francisco study reveals how Philip Morris Companies Inc. used cigarette research, flavor engineering, and behavioral science to turn Lunchables into one of America's most successful ultra-processed foods for children. https://medicalxpress.com/news/2026-06-big-tobacco-ultra-foods.html Wed, 03 Jun 2026 14:20:01 EDT news699712650 A major international study led by researchers at the Kennedy Institute of Rheumatology at the University of Oxford has found that osteoarthritis (OA)—the most common form of arthritis worldwide—is not a collection of separate diseases, as many scientists had previously speculated, but rather a single condition with common core underlying biological pathways. https://medicalxpress.com/news/2026-06-largest-knee-osteoarthritis-tissue-reveals.html Tue, 02 Jun 2026 15:20:02 EDT news699623101 Newborn meningitis is one of the most dangerous childhood infections. It is often life-threatening and can cause serious and lasting damage, including developmental problems, in the children who survive. Although meningitis is thankfully rare in newborns as a whole, it is more common in premature babies, affecting one in every 500 such infants in industrialized economies and likely more in developing countries. https://medicalxpress.com/news/2026-06-triple-therapy-block-newborn-meningitis.html Mon, 01 Jun 2026 13:20:04 EDT news699533041 According to research from the University of East Anglia (UEA), young people are far more likely to encounter illicit vaping content portrayed as normal, humorous and harmless on TikTok. Meanwhile, evidence-based health advice on official health and education websites may fail to cut through the digital noise. https://medicalxpress.com/news/2026-05-tiktok-content-illicit-vape-subculture.html Sun, 31 May 2026 19:10:06 EDT news699262922 Online information about artificial intelligence (AI) and its impact on cancer research and treatment for both the patient and general-public audiences is limited, and the available webpages and videos are largely of low quality, difficult to read, and frequently omit risks of AI use, according to new research presented at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting and led by researchers from the Abramson Cancer Center (ACC) of the University of Pennsylvania and Penn's Perelman School of Medicine. https://medicalxpress.com/news/2026-05-highlights-major-gaps-online-info.html Sun, 31 May 2026 10:50:01 EDT news699277261 Switching off an enzyme that plays an important role in sugar metabolism, glycolysis, would normally be expected to cause serious problems for cells. Surprisingly, the opposite is also true: Cells can become highly resistant to a specific form of cell death known as ferroptosis.⮐ https://medicalxpress.com/news/2026-05-inhibitor-outcome-effect-reshape-ferroptosis.html Sat, 30 May 2026 06:08:06 EDT news699340017 Being admitted to a mental health unit can be one of the most vulnerable moments in a person's life. They often arrive in the midst of a crisis, and are fearful, confused, and anxious. But in these situations, one thing can profoundly affect their experience: the relationship established with the nurses who attend them, especially in the first days. https://medicalxpress.com/news/2026-05-patientnurse-relationships-mental-health-hospital.html Fri, 29 May 2026 19:40:01 EDT news699268880 An international research team led by Istituto Italiano di Tecnologia (IIT-Italian Institute of Technology) in Rovereto (Trento, Italy) and the Child Mind Institute in New York (U.S.), and in collaboration with researchers from the University of Trento, has shown that it is possible to identify at least two distinct subtypes of autism, defined by their patterns of brain connectivity. In the "hyperconnectivity" subtype, brain areas communicate more than usual; in the "hypoconnectivity" subtype, communication between brain areas is reduced. https://medicalxpress.com/news/2026-05-brain-scans-reveal-distinct-autism.html Fri, 29 May 2026 15:20:03 EDT news699280623 Bans on teenagers' social media use are gathering pace worldwide. Their proponents claim that social media bans will improve young people's mental health, but what evidence supports these claims? In their new Frontiers in Developmental Psychology article, Dr. Monika Neff Lind and her co-authors argue that there is no solid scientific evidence behind these bans, and reason to believe they could backfire. https://medicalxpress.com/news/2026-05-social-media-teenagers-lack-evidence.html Fri, 29 May 2026 13:20:05 EDT news699268572 A research team led by Associate Professor Noriyuki Kurita from the Department of Computer Science and Engineering at Toyohashi University of Technology and by Associate Professor Pornpan Pungpo from Ubon Ratchathani University in Thailand has proposed a novel therapeutic agent for tuberculosis, using high-precision molecular simulation techniques. https://medicalxpress.com/news/2026-05-simulation-uncovers-tuberculosis-drug-candidates.html Fri, 29 May 2026 11:20:05 EDT news699269760 Millions of people use a wearable health and fitness tracker.

They used this model to show how damage to these connections previously considered "irreversible" could, in fact, be reversible. https://medicalxpress.com/news/2026-05-lab-grown-brain-spinal-cord.html Thu, 28 May 2026 16:20:05 EDT news699200617 Many cancers can be treated by administering DNA-damaging agents, such as platinum-based chemotherapy, because the resulting DNA damage causes the cancer cells to die. A subset of cancers, however, including ovarian cancers, can repair their own DNA. Because such cancers survive despite chemotherapy, ovarian cancer patients whose tumors are DNA repair proficient have historically faced a poor prognosis and commonly recur within six months. https://medicalxpress.com/news/2026-05-scientists-metabolic-chemotherapy-resistance-ovarian.html Thu, 28 May 2026 14:20:03 EDT news699191699 Headlines might describe meat as "a significant health risk" or "essential for a healthy and balanced diet." https://medicalxpress.com/news/2026-05-big-meat-science-steak-healthy.html Thu, 28 May 2026 12:40:03 EDT news699186122 Valley Fever, technically known as Coccidioidomycosis, is a dust-borne fungal infection that occurs in dry regions like the southwestern US and is proliferating in California and Arizona.

But along with the influx of visitors comes a rise in wilderness emergencies, some of them requiring complex and expensive search-and-rescue operations. In a single week in April in New Hampshire's White Mountains, seven hikers were rescued and another was found dead on a trail after he didn't return from a solo backpacking trip. https://medicalxpress.com/news/2026-05-qa-chances-youre-safety-gear.html Tue, 26 May 2026 14:40:02 EDT news699020401 Obtaining home care for older adults with Medicaid can be a complex, multi-step process marked by delays and uncertainty, often resulting in long wait times, according to a new Weill Cornell Medicine study. Medicaid is a joint federal and state program that millions of Americans with limited income and resources depend on for free or low-cost health coverage, including the help needed to age at home. https://medicalxpress.com/news/2026-05-york-families-maze-medicaid-funded.html Tue, 26 May 2026 14:20:03 EDT news699021421 While we tend to quickly forget having been ill or having received a vaccine, the immune system remembers remarkably well. It has memory B cells—"trained" immune cells that circulate throughout the body in search of harmful invaders they have encountered previously; these cells can rapidly deploy targeted weapons when faced with a pathogen again. Now, researchers from Prof. Ziv Shulman's laboratory at the Weizmann Institute of Science report that activated memory B cells can also recognize an internal enemy: cancer cells. https://medicalxpress.com/news/2026-05-immune-memory-cells-ovarian-cancer.html Tue, 26 May 2026 13:00:05 EDT news699016382 Researchers from the National University of Singapore (NUS) have developed an AI-guided workflow that combines artificial intelligence (AI) with molecular simulations to identify potential drug candidates for diabetic wound healing, identifying folic acid, a common vitamin, as a top candidate. https://medicalxpress.com/news/2026-05-ai-drug-flags-folic-acid.html Mon, 25 May 2026 16:00:03 EDT news698942821
