Today’s wolves and dogs share a common ancestor. But a deeper look at their genes reveals that interbreeding since dogs were domesticated 20,000 years ago hasn’t been as rare as scientists assumed.

Boeing and NASA have agreed to keep astronauts off the company’s next Starliner flight and instead perform a trial run with cargo to prove its safety.  Monday’s announcement comes eight months after the first and only Starliner crew returned to Earth aboard SpaceX after a prolonged mission.  Although NASA test pilots Butch Wilmore and Suni Williams managed to dock Starliner to the International Space Station in 2024, the capsule had so many problems that NASA ordered it to come back empty, leavi
