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.

‘Inky’ makes escape

WELLINGTON, New Zealand—“Inky” the octopus waited until it was dark, and the staff had gone home from the National Aquarium of New Zealand, before making his move.

He squeezed and pushed his way through a tiny gap in the mesh at the top of his tank and slithered three metres to the floor.

Brain implant lets paralyzed man regain use of hand

NEW YORK — A paralyzed 24-year-old man has regained some use of his right hand, controlling it with signals relayed from electronic sensors in his brain.

Ian Burkhart of Dublin, Ohio, can grasp a bottle, pour its contents into a jar, pick up a stick and stir the liquid. He can grab a credit card and swipe it through a reader. He can move individual fingers and hold a toothbrush.

Global warming shifting Earth’s wobble

WASHINGTON—Global warming is shifting the way the Earth wobbles on its polar axis, a new NASA study finds.

Melting ice sheets, especially in Greenland, are changing the distribution of weight on Earth.

And that has caused both the North Pole and the wobble, which is called polar motion, to change course, according to a study published Friday in the journal, “Science Advances.”
