...putting dinosaur traits on chickens. The goal, of course, is to understand how dinosaurs became birds (And I remember when that was a vague theory not everyone believed).
Fortunately for those of us worried about dinosaur-chicken chimeras, the altered chicks failed to hatch. Otherwise they'd have had big long legs on regular chicken bodies. Which I suppose would be kind of cute.
Other scientists found a T-Rex with a medulla bone. This is a bone female birds literally grow when they conceive, use to help them lay eggs, and then reabsorb. That makes this the first time we have actually sexed a dinosaur...and if we can find more it might tell us things like, say, which sex of certain species grew large crests.
