'DNA Typewriter' records cells' history in developing mouse embryo

Scientists have succeeded in reconstructing the family tree of cells in a developing mouse embryo. They recorded cells' relationships, starting when the fertilized egg first split in two and ending after the body and its organs took shape. That period lasted 13.5 days. (Full gestation in mice is 19 to 21 days.)

8 fierce animals show just how metal nature is

Nature. It’s beautiful. It’s awe-inspiring. And it’s really scary. The new book Nature is Metal: It’s A Life-Eats-Life World features full-color photographs and vivid descriptions of the physical features, survival adaptations, and hunting skills innate to 75 of nature’s most metal plants, animals, and natural phenomena. Browse through some of these raw and real images in the gallery below. (Click to expand images to full screen.) A golden eagle (Aquila chrysaetos) eating the remains of a bison. They are hypercarnivores whose diets are at least 70 percent meat. Image: Natasha Mace. Stoats (Mustela erminea) may look pretty cute, but these short-tailed weasels are known for opportunistic and frenzied killing. Image: Grayson Smith/UWSFWS. A giant otter (Pteronura brasiliensis) holds a swamp eel in its powerful grip. Image: Parks Marilla. Polar bears (Ursus maritimus) have been known to eat cubs when food is extremely scarce. Image: Jacob Zoller Jake Zoller Leopard seals (Hydrurga leptonyx) may look like cats, but they hunt their prey like sharks. They are at the top of the food chain in the seas around Antarctica.

Stygian owls (Asio stygius) are found across Latin America and the Caribbean and called coruja-diabo or “devil’s owl” in Brazil. Image: Eigi Iwasaki.
