## Resource

Researchers have discovered preserved blood vessels inside a T. rex rib bone that was healing 66 million years ago, uncovering new details about ancient soft tissue preservation in fossils. A major genetic study has upended the long-held theory of human origins, revealing that modern humans evolved from multiple intermingling populations across Africa rather than a single ancestral group. Scientists are now reporting evidence of a hidden structure deep within Earth's inner core, suggesting our models of planetary formation may need a serious rethink. On the medical front, a blood test has shown it can detect Alzheimer's disease years before brain scans catch any changes, aspirin is showing promise in preventing colorectal cancer recurrence, and a gut bacterium has been linked to depression through a surprising molecular pathway. Rounding out the week, nanorobots smaller than a human hair can now hunt and capture individual bacteria, and a plant thought extinct for 60 years has just been rediscovered thanks to a citizen scientist with a smartphone.
