Blood vessels found in T. rex bones are rewriting dinosaur science
Dinosaur DNA may still be out of reach, but scientists are uncovering something almost as exciting—ancient blood vessels hidden inside fossilized bones. In a massive Tyrannosaurus rex nicknamed Scotty, researchers discovered a network of preserved vessels within a rib that once fractured and began healing 66 million years ago. Using powerful synchrotron X-rays from particle accelerators, they were able to peer inside the dense fossil without damaging it, revealing intricate, iron-rich structures left behind by the healing process.

DNA research just rewrote the origin of human species
Scientists have uncovered a surprising new picture of human origins that challenges the long-held idea of a single ancestral population in Africa. By analyzing genetic data from diverse modern African groups—especially the highly distinct Nama people—and comparing it with fossil evidence, researchers found that early humans likely evolved from multiple intermingling populations over hundreds of thousands of years. Rather than a clean split, these groups stayed connected, exchanging genes even after beginning to diverge around 120,000–135,000 years ago.

Mezcal worm in a bottle DNA test reveals a surprise
The famous mezcal “worm” has long puzzled scientists, but DNA testing has finally cracked the case. Researchers found that all sampled larvae were actually agave redworm moth caterpillars—not a mix of species as once believed. While the discovery clears up a long-standing mystery, it also raises concerns about sustainability. Growing demand for mezcal and edible larvae could put pressure on wild populations and the agave plants they depend on.

Warming waters are supercharging an invasive salmon predator in Alaska
As Alaska’s rivers warm, invasive northern pike are becoming noticeably more voracious. Scientists discovered that pike of all ages are eating more fish, with young pike increasing consumption by over 60%. Warmer water speeds up their metabolism, pushing them to hunt more. This growing appetite could spell trouble for struggling salmon populations.

Giant prehistoric insects didn’t need high oxygen after all, study finds
Ancient Earth once buzzed with enormous dragonfly-like insects, and scientists long thought high oxygen levels made their size possible. A new study overturns that idea, revealing insect flight muscles weren’t constrained by oxygen after all. Their breathing system has plenty of room to expand, meaning oxygen alone can’t explain their giant forms. Now, researchers are searching for new answers—like predators or physical limits of their bodies.
