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.

Scientists have developed a chromium-molybdenum-silicon alloy that withstands extreme heat while remaining ductile and oxidation-resistant. It could replace nickel-based superalloys, which are limited to about 1,100°C. The new material might make turbines and engines significantly more efficient, marking a major step toward cleaner, more powerful energy systems.

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 suggest new imaging-based approaches to assessing cardiovascular risk.

Chalmers researchers have developed a simple, light-based platform to study the mysterious “invisible glue” that binds materials at the nanoscale. Gold flakes floating in salt water reveal how quantum and electrostatic forces interact through vivid color changes. The technique could lead to new discoveries in physics, chemistry, and biology — from designing biosensors to understanding how galaxies form.
