Insights From Rare Mummified Dinosaur Skin

Insights into the Mesozoic era usually come from fossilized bones, making the preserved skin of “Dakota”—a duck-billed dinosaur from an Edmontosaurus specimen—particularly rare. The finding, discovered in South Dakota in 1999, is uncommon because skin is trickier than bones to preserve but new research makes the discovery even more peculiar. Previously, scientists believed that preserved soft tissue had to be buried immediately after death or …

Scientists Discover Ancient Cities in the Amazon

In the Llanos de Mojos region of the Bolivian Amazon, scientists recently discovered remnants of vast urban settlements, proving the existence of ancient Amazonian cities. Using a light-based remote sensing technology called lidar, scientists digitally deforested the canopy to survey the ruins beneath it. They found a stronghold of the socially complex Casarabe Culture (who existed from 500 to 1400 CE) who built urban centers, …

World’s First Living Robots Can Now Reproduce

Last year, researchers in the US created the world’s first living machine, called xenobots. Composed of bundles of stem cells from the African clawed frog (xenopus laevis), the new life form was programmed to accomplish tasks and move microscopic objects around. Now, they can reproduce. “One [xenobot] parent can begin a pile and then, by chance, a second parent can push more cells into that …
