Scientists have found a "new" horned dinosaur that lived about 79 million years ago — and they say the discovery helps them understand the early evolution of the family that includes Triceratops.

The new dinosaur, which was named Wendiceratops pinhornensis after a famous fossil hunter who discovered the bone bed in Canada where these fossils were buried, is one of the oldest known horned dinosaurs.

It has taken nearly a decade and 3 billion miles to get there, but scientists are about to get their first look at Pluto.

The New Horizons spacecraft is closing fast on the tiny world once thought to be at the edge of our solar system. On Tuesday the probe will begin an intensive nine-day scientific study of Pluto and its moons.

The Washington National Guard -- joined by officers from Oregon and Idaho -- are preparing for a massive military relief effort.

Toddlers can throw their fair share of tantrums, especially when you don't yield to their will. But by age 3, it turns out, the little rug rats actually have a burgeoning sense of fairness and are inclined to right a wrong.

When they see someone being mistreated, children as young as 3 years old will intervene on behalf of others nearly as often as for themselves, a study published this month in Current Biology suggests. Just don't ask them to punish the perpetrator.

New images of Ceres are the clearest ever taken, but NASA's scientists still haven't figured out the enigmatic dwarf planet. The agency's latest photos of Ceres show multiple bright spots — and a "pyramid-shaped peak towering over a relatively flat landscape."

That's according to an update posted by the space agency, saying that Ceres and its bright spots "continue to mystify."

Professor John Marzluff’s phone is ringing more than usual, which means it’s crow dive-bombing season in Seattle.

“Every time I go out into my backyard there's a crow out there that's squawking at me and chasing me down,” said a man who called in about his experience to KUOW.

A virus is being blamed for killing millions of West Coast sea stars, but it's unclear why the disease is hitting so hard.

A couple of years ago, divers in Puget Sound began to notice something odd: Starfish were disappearing.

The sea creatures would get sores and then melt into piles of mush. Sea star wasting syndrome is a gruesome disease and it spread to starfish all along the West Coast. Scientists still don't know a lot about it.

Last November, the European Space Agency wasn't sure if it would ever hear from its Philae lander again after the probe's unfortunate landing spot on Comet 67P/Churyumov-Gerasimenko left it in the shadow of a cliff, starving its solar panels of the faint sunlight needed to produce power.

In the NFL, something that behaves like Pluto's football-shaped moons might be called a wobbly duck. NASA simply calls them astonishing.

Instead of steadily rotating through their orbits, two of Pluto's moons "wobble unpredictably," the space agency says, citing new analysis of data from the Hubble Space Telescope.

Jiya Bavishi was born deaf. For five years, she couldn't hear and she couldn't speak at all. But when I first meet her, all she wants to do is say hello. The 6-year-old is bouncing around the room at her speech therapy session in Dallas. She's wearing a bright pink top; her tiny gold earrings flash as she waves her arms.

"Hi," she says, and then uses sign language to ask who I am and talk about the ice cream her father bought for her.

Earlier this spring, headlines around the world trumpeted an exciting bit of news that seemed too good to be true: "Eating chocolate ... can even help you LOSE weight!" as Britain's Daily Mail put it.

The nationwide weirdness that was the Windshield-Pitting Mystery began in the spring of 1954. Looking back at the events today may give us a window — OK, a windshield — on the makeup and the mindset of mid-20th-century America.

A large bone from a two-legged, meat-eating dinosaur has been discovered in the San Juan Islands – the first dinosaur fossil ever found in Washington state.

Researchers found the fossil by accident. In 2012, they were in Sucia Island State Park collecting sea creature fossils when they stumbled on a bone that looked unusual for that area.

A month later they returned to the site with paleontologists. Initially, Professor Christian Sidor of the Burke Museum didn’t believe it belonged to a dinosaur.  

But one feature of the bone convinced Sidor, a professor of biology at the University of Washington and vertebrate curator at the Burke Museum: “The muscles that actually attach to the back of the leg and retract the femur attach here. So this structure, the shape of it, and how close it is to the head of the femur tell us that this is a carnivorous dinosaur. All dinosaurs have this feature.”  

The scientists don’t know what kind of dinosaur the bone comes from, however, because there’s only a third of the bone. Sidor said it’s likely a therapod, which includes Tyrannosaurus rex, birds and Velociraptors. And they are pretty sure it is from the Late Cretaceous period and is about 80 million years old.
