If 75M-year-old soft tissue has survived, could DNA, too?

(Newser) - The fossils may be in such poor shape that scientists are calling them "crap," but the 75-million-year-old fragments are golden in another sense. A theropod claw, triceratops-like toe bone, and duck-billed dinosaur limb and ankle bones first unearthed in Canada 100 years ago appear to retain soft tissue,...

No problem, scientists say, after apparently figuring out, finally, where these mystery creatures sit on the mammalian family tree, Nature reports. Charles Darwin discovered fossils of these ancient creatures while visiting South...

(Newser) - In a frontier-busting surgery, transplant doctors have given a young woman a trachea developed in a lab using the patient's own stem cells. Stem cells from the patient's trachea and bone marrow were used to create a new rejection-proof organ in the surgery, performed in Spain in June, reports the...

Tyrannosaurus Rex: Tastes Like Chicken?

Study says birds are dinosaurs' closest living descendants

(Newser) - Dinosaurs are more closely related to birds than reptiles, protein extracted from a Tyrannosaurus rex bone suggests. T. rex collagen, the main protein in bones, is similar to chicken and ostrich collagen but much different than material from alligators and lizards, scientists say. The findings could remap the evolutionary tree...
