Sometimes this drive leads us to a tangible reward, such as looking up reviews to find the perfect restaurant. But often we seek knowledge as an end unto itself, as when Galileo pointed his telescope at the night sky or Alice followed the rabbit down its hole. How do our brains lead us on such curiosity-driven quests for information? https://medicalxpress.com/news/2026-07-mice-advance-knowledge-rewards.html Thu, 30 Jul 2026 17:40:03 EDT news704648761 Early vitrectomy surgery for acute endophthalmitis, a rare eye condition, may potentially benefit patients' vision more than the current antibiotic-first approach, according to a study led by researchers at University College London (UCL) and Moorfields Eye Hospital. https://medicalxpress.com/news/2026-07-early-surgery-bacterial-eye-infection.html Thu, 30 Jul 2026 17:20:06 EDT news704648101 Every day in the urban slums of Mumbai, hundreds of young children were fed toddler-appropriate porridge, soft curry or fresh-baked goods. For some, these were made of ordinary pearl millet, an ancient grain common in the Indian diet. For others, they were made of a specially bred variety packed with nearly three times the iron and more zinc than typical grain. The difference was largely imperceptible on the palate. But deep in the children's guts, something meaningful was beginning to happen. https://medicalxpress.com/news/2026-07-supercharged-millet-children-gut-health.html Thu, 30 Jul 2026 17:00:06 EDT news704646035 Many people who survive a heart attack will later develop heart failure due to the scarring that occurs as the heart heals. Researchers at Uppsala University are now presenting a new type of biological treatment that is administered directly into the damaged blood vessel and stimulates healing.
