Researchers have demonstrated that human DNA in fecal matter, previously ignored as biological noise, provides a clear map of activity in Inflammatory Bowel Disease. https://medicalxpress.com/news/2026-05-inflammatory-bowel-disease-human-dna.html Thu, 07 May 2026 19:40:03 EDT news697365830 Household contacts of people with tuberculosis (TB) have a high risk of getting TB themselves, at around 2%. It is currently difficult to detect TB in its early stages, or predict who will go on to have TB, and therefore preventive treatment is not widely used. Most contacts are asymptomatic and current approaches rely mainly on symptom-based screening and sputum testing, which often miss early or hidden disease. As a result, many infections are only identified once the disease has progressed. https://medicalxpress.com/news/2026-05-finger-blood-tuberculosis-early-disease.html Thu, 07 May 2026 19:20:05 EDT news697389842 Involving a collaboration with 118 investigators contributing from 89 institutions, scientists from Queen Mary University of London's Precision Healthcare University Research Institute and Berlin Institute of Health (BIH) at Charité have led the world's largest study on the genetic regulation of blood proteins. https://medicalxpress.com/news/2026-05-blood-protein-people-uncovers-disease.html Wed, 06 May 2026 15:20:27 EDT news697289341 Scientists are developing a test which could one day be used to predict how a patient's illness will progress, and even how well they will respond to treatment. The international team, led by researchers at Imperial College London, has already tested their method (called VeloCD) to successfully predict patients' outcomes for a range of health conditions, including the likely progression of infectious and chronic disease. https://medicalxpress.com/news/2026-05-rna-blood-markers-reveal-illness.html Wed, 06 May 2026 14:20:05 EDT news697288021 QIMR Berghofer scientists have developed an AI screening tool that harnesses the power of cutting-edge spatial biology analysis to give pathologists "super vision" to detect hidden genetic markers of cancer in standard patient tissue samples. https://medicalxpress.com/news/2026-05-ai-screening-tool-pathologists-spatial.html Wed, 06 May 2026 13:40:02 EDT news697281426 A simple blood test can reveal the geographic relationships among healthy cells surrounding a cancerous tumor, researchers at Stanford Medicine and the Mayo Clinic have found.
