Yes, you can buy happiness: study

WASHINGTON—Yes, you can buy happiness—especially if the money saves you time.

People who dole out cash to save time on things like housekeeping, delivery services, and taxis are a little bit happier than those who don't, new research finds.

Researchers surveyed more than 6,000 people in four countries and also ran an experiment, giving people $40 for two weeks.

Another planet may be just right for life

WASHINGTON—Astronomers have found yet another planet that seems to have just the right “Goldilocks” combination for life: not so hot and not so cold.

It's not so far away, either.

This new, big, dense planet is rocky, like Earth, and has the right temperatures for water—putting it in the habitable zone for life, according to a study published yesterday in the journal “Nature.”

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.”
