Dinosaurs are often depicted as large beasts roaming through tropical forests or across hot deserts — and the humid jungle of Jurassic Park may have gone a long way to solidify those images.

But a study out today in the journal Current Biology contradicts those ideas. It suggests that these creatures also lived year-round in what's now northern Alaska, where they endured freezing winters, snow, and months of darkness.

Most of us learned about the world's oceans in elementary school. There's the Pacific, the Atlantic, the Indian and the Arctic.

Now, there's a sea change ahead.

Thanks to National Geographic, you'll soon see a fifth ocean on your maps. It's now officially recognizing the Southern Ocean, the waters swirling around Antarctica, marking the first time the organization has made such a change since it started drawing up maps over a century ago.

After 17 years underground, the Brood X periodical cicadas are slowly emerging in 15 states across the East Coast and Midwest.

They'll shed their skins and spend four to six weeks mating before the females lay eggs and they all die.

But some of them are getting wilder in their short lives above ground.

A fungus called Massospora, which can produce compounds of cathinone — an amphetamine — infects a small number of them and makes them lose control.

Overnight, violence in the Gaza Strip and Israel accelerated to the brink of all-out war.

Israel deployed artillery and warplanes to attack the tunnel systems of Hamas. The Palestinian Health Ministry reports at least 126 dead.

Tanitoluwa Adewumi, a 10-year-old in New York, just became the country's newest national chess master.

At the Fairfield County Chess Club Championship tournament in Connecticut on May 1, Adewumi won all four of his matches, bumping his chess rating up to 2223 and making him the 28th youngest person to become a chess master, according to US Chess.

"I was very happy that I won and that I got the title," he says, "I really love that I finally got it."
