Scientists have discovered a hidden warning sign of skin damage that appears before collagen fibers visibly thin, break, or lose their connections. Using advanced light-based techniques, the team found that collagen’s carefully organized molecular “handedness” can collapse even while the tissue still appears structurally intact and contains the same amount of collagen. This suggests that skin may begin deteriorating at a much deeper level long before conventional imaging can detect a problem.
Two elephant-sized South American sauropods were unusually well built for standing on their hind legs. Digital tests showed that their robust femurs handled the enormous forces better than those of larger species, especially while the dinosaurs were young. The upright pose may have helped them reach treetops, frighten predators, or impress potential mates.
Oxygen is disappearing from oceans, lakes, rivers, and coastal waters at an alarming rate, threatening aquatic life and weakening the natural processes that help regulate Earth’s climate. Scientists warn that this widespread deoxygenation is closely connected to other major planetary threats, including warming, pollution, biodiversity loss, and ocean acidification.

Climate activist Sonam Wangchuk has a long history of challenging the status quo and refusing food to highlight his causes.

Erin Davis calls it the “SuperDuperPOD.” That’s two things in one name: pharmaceutical giant Bristol Myers Squibb (BMS) already runs one of the largest AI clusters in life sciences, with serious results to show for it. And they’re doubling down. BMS announced today it is deploying its second NVIDIA DGX SuperPOD, this one built on […]
