Ovarian cancer kills more women than any other gynecological cancer. Most patients receive their diagnosis only after the disease spreads throughout the abdomen. Until now, scientists have never fully understood why this cancer advances so fast. https://medicalxpress.com/news/2026-02-scientists-ovarian-cancer-rapidly-abdomen.html Fri, 06 Feb 2026 14:00:01 EST news689592481 For some women, pregnancy is a time of profound loss. Not all pregnancies progress as expected. One serious complication is ectopic pregnancy, a condition in which a fertilized egg implants somewhere other than the uterus. https://medicalxpress.com/news/2026-01-stone-baby-rare-condition-calcified.html Wed, 28 Jan 2026 20:10:01 EST news688816979 A bitter taste has always been considered a warning signal, devoted to protecting us from ingesting potentially harmful substances. But bitter taste receptors can apparently do much more than just evaluate the taste of food. A study by the Leibniz Institute for Food Systems Biology at the Technical University of Munich now shows that certain human bitter taste receptors also respond to steroid hormones. They could therefore play a previously underestimated role in physiological processes. https://medicalxpress.com/news/2026-01-bitter-receptors-interface-nutrition-endocrine.html Wed, 28 Jan 2026 14:50:31 EST news688834201 A collaborative research team has developed the world's first AI-based optical diagnostic platform that enables rapid and accurate differentiation—within minutes—between ordinary nasal secretion and cerebrospinal fluid (CSF) leaking from the nose.
