Cedars-Sinai researchers created “young” immune cells from human stem cells that reversed cognitive decline and Alzheimer’s symptoms in mice. The treated animals showed better memory and healthier brain structures. The cells seemed to protect the brain indirectly, possibly through anti-aging signals in the blood. The findings suggest a new, personalized path to slowing brain aging. …

MIT scientists have found that an amino acid called cysteine can help the gut heal itself. In mouse studies, a cysteine-rich diet activated immune cells that release a molecule speeding up tissue repair in the small intestine. This process helped regenerate the gut lining after damage from radiation or chemotherapy. ​MIT scientists have found that …

McMaster researchers found that deep abdominal and liver fat can quietly damage arteries, even in people who appear fit. Their MRI-based study of over 33,000 adults shows these fats are closely linked to artery thickening and stroke risk, regardless of cholesterol or blood pressure. The findings challenge BMI as a reliable indicator of health and …

New research reveals that Earth’s continents owe their stability to searing heat deep in the planet’s crust. At more than 900°C, radioactive elements shifted upward, cooling and strengthening the landmasses that support life. This ancient heat engine also distributed valuable minerals, giving scientists new clues for exploration and for spotting potentially habitable planets. ​New research …
