A new human liver organoid microarray developed by Cincinnati Children’s and Roche recreates immune-driven liver injury in the lab. Built from patient-derived stem cells and immune cells, it accurately models how genetics influence drug reactions. The system replicated flucloxacillin-related toxicity seen only in people with a specific genetic variant, marking a major step toward predictive, …

Scientists discovered that specific nutrients in nematodes’ diets activate stress defenses that keep their cells healthier over time. These RNAs prevent toxic protein buildup, promoting longevity and vitality. The worms fed with balanced diets lived more active, healthier lives. The findings hint that mild dietary stress could support better aging in humans as well. Scientists …

Scientists have discovered that bacteria living inside tumors can produce a molecule that fights cancer and enhances chemotherapy. The molecule, called 2-methylisocitrate (2-MiCit), was found to make colorectal cancer cells more vulnerable to chemotherapy by damaging their DNA and disrupting their metabolism. Experiments using worms, flies, and human cancer cells confirmed its potent anti-cancer effects. …

Researchers at KAUST have confirmed that the Red Sea once vanished entirely, turning into a barren salt desert before being suddenly flooded by waters from the Indian Ocean. The flood carved deep channels and restored marine life in less than 100,000 years. This finding redefines the Red Sea’s role as a key site for studying …

Endurance exercise may train the immune system as much as the muscles. Older adults with decades of running or cycling had immune cells that functioned better and aged more slowly. Their inflammation levels were lower and their cells resisted fatigue even under stress. The findings point to a direct link between lifelong fitness and healthier …
