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...

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...
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...
Aggressive “hulk” lizards are wiping out millions of years of evolution
For ages, wall lizards coexisted in three distinct color types, each with its own strategy for survival. Now, a powerful green variant is taking over. These dominant “Hulk” lizards are outcompeting the others, causing yellow and orange morphs to vanish. It’s a dramatic reminder that evolution can flip the script...
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 octopuses may have ruled the oceans 100 million years ago
Giant, fearsome octopuses may have once ruled the ancient seas, according to new research that flips the script on their evolutionary past. By uncovering exquisitely preserved fossil jaws hidden inside rock, scientists revealed that early octopuses from the age of dinosaurs weren’t shy, soft-bodied drifters—they were massive apex predators, possibly...
Scientists just discovered Africa is closer to breaking apart than we thought
Beneath East Africa’s Turkana Rift, scientists have found the crust is thinning to a critical point, suggesting the continent is gradually breaking apart. This “necking” process marks an advanced stage of rifting that could eventually lead to a new ocean forming millions of years from now. Surprisingly, the same geological...
Fires, Droughts, and Windstorms Reduce the Diversity of Amazonian Vegetation
Even after fires, severe droughts, and windstorms, the vegetation in degraded Amazonian forests demonstrates a high capacity for regeneration, including tree species.
Beavers Leave a Trail as They Head into the Arctic
A study has provided new evidence of beavers’ expansion into the Canadian Arctic by dating the changes they have made to the tundra landscape as they spread northwards.
Lost Millennium of Galápagos Deep-Sea Corals Linked to Major Pacific Climate Shift
The research, led by the University of Bristol in collaboration with international scientists and published in PNAS today [insert date], analysed more than 900 fossil deep-sea stony corals collected from depths of up to 1,000 metres.
