Dinos decline cited

NEW YORK—Dinosaurs were in decline long before an asteroid strike polished them off about 66 million years ago, a study says.

It’s the latest contribution to a long-running debate: did the asteroid reverse the fortune of a thriving group of animals?

Or were dinosaurs already struggling—and the disruptive effects of the asteroid pushed them over the edge to extinction?

Space probe supported

NEW YORK—With famed physicist Stephen Hawking at his side, an Internet investor announced Tuesday that he’s spending $100 million on a futuristic plan to explore far outside our solar system.

Yuri Milner said the eventual goal is sending hundreds or thousands of tiny spacecraft—each weighing far less than an ounce—to the Alpha Centauri star system.
