Long before humans built cities or wrote words, our ancestors may have faced a hidden threat that shaped who we became. Scientists studying ancient teeth found that early humans, great apes, and even Neanderthals were exposed to lead millions of years ago. This toxic metal can damage the brain, yet modern humans developed a tiny …

Mars may look calm, but new research reveals it’s a world of fierce winds and swirling dust devils racing at hurricane-like speeds. Using deep learning on thousands of satellite images from European orbiters, scientists have discovered that Martian winds can reach up to 160 km/h — much stronger than previously thought. These powerful gusts play …

Scientists at EPFL have reimagined 3D printing by turning simple hydrogels into tough metals and ceramics. Their process allows multiple infusions of metal salts that form dense, high-strength structures without the porosity of earlier methods. Early results show materials 20 times stronger with much less shrinkage. The breakthrough could lead to efficient production of complex …
Scientists grow metal instead of 3D printing it — and it’s 20x stronger Read More »

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 …
