MATTAWA, Wash. – Kennewick Man spent most of his life on the coast, not in the region on the Columbia River where he was found. So says the federal scientist who fought for nearly 10 years to study the 9,500 year old bones. The scientist released some of his findings at a conference this week with Northwest tribes

Kennewick Man’s bones give an indication of what he ate, and how he lived. The research shows he wasn’t fond of oysters or clams but instead his menu included big sea creatures like seals.

Here’s a solution for space junk – gas it.

A Boeing engineer from Seattle, Michael Dunn, has filed a patent for a method of dragging parts, pieces and defunct satellites into the atmosphere where they will burn up.

Geek speak: “… the method comprising hastening orbital decay of the debris by creating a transient gaseous cloud at an altitude of at least 100 km above Earth, the cloud having a density sufficient to slow the debris so the debris falls into Earth's atmosphere,” according to the document.

Even if you never smoke marijuana, Initiative-502 could make it much more a part of our society, like alcohol. In our series “If it’s legal: Five ways legal pot could affect your life,” we consider some ways things could change for all of us. Today, we look at what sort of advertising and public messages we might expect to see.

If you turn on the TV today, beer and wine are everywhere. A typical commercial for Corona Light, for example, features a guy whose life improves with girls, dancing, lively music, a great time – all thanks to a frosty beer.

This sort of commercial is what Denise Walker was imagining, when she started thinking about the possibility of marijuana advertising in the future.

For the past decade, scientists have been toying with the notion of encapsulating medicine in microscopic balls.

These so-called nanospheres could travel inside the body to hard-to-reach places, like the brain or the inside of a tumor. One problem researchers face is how to build these nanospheres, because you'd have to make them out of even smaller nanoparticles.

David Wineland is the American half of the scientific duo celebrating the award of the Nobel Prize in Physics today.

Wineland and French scientist Serge Haroche developed new ways for scientists to observe individual quantum particles without damaging them. This may not sound so impressive, but the work opens a world of possibilities— including the development of a quantum computer and super-precise clock.

But who needs a better clock? Don't we have pretty good ones already?

The 2012 Nobel Prize in Physics has been awarded to Serge Haroche of France and David Wineland of the United States for their work on the "fundamental interactions between light particles and matter."

"The Nobel laureates have opened the door to a new era of experimentation with quantum physics by demonstrating the direct observation of individual quantum particles without destroying them," the Royal Swedish Academy of Sciences said in a statement.

The two scientists who won this year's Nobel Prize in Physiology or Medicine discovered that cells in our body have the remarkable ability to reinvent themselves. They found that every cell in the human body, from our skin and bones to our heart and brain, can be coaxed into forming any other cell.

Columbus, they say, crossed the Atlantic at a speed of roughly four knots. That's four-plus miles an hour. When the wind gusted, he could hit 9.2 mph. In 1492, that was speedy.

This is how we do it.

This is how they do it.

Scientists in Japan report they have created eggs from stem cells in a mammal for the first time. And the researchers went on to breed healthy offspring from the eggs they created.

While the experiments involved mice, the work is being met with excitement — and questions — about doing the same thing for humans someday.

What we learn about dinosaurs keeps surprising us. Today in the journal ZooKeys we get a peek into an odd, new kind of dinosaur that was lighter than a house cat and just as small but had a terrifying set of teeth and a short, birdlike beak.

The fossil used to re-create the creature was actually discovered in southern Africa in the 1960s, but it is described for the first time today by Paul Sereno, paleontologist and professor at the University of Chicago.

You are 200 miles directly above the Martian surface — looking down. This image was taken by the Mars Reconnaissance Orbiter on Jan. 27, 2010. (The color was added later.) What do we see? Well, sand, mostly. As you scroll down, there's a ridge crossing through the image, then a plain, then dunes, but keep looking. You will notice, when you get to the dunes, there are little black flecks dotting the ridges, mostly on the sunny side, like sunbathing spiders sitting in rows. Can you see them?

The Puget Sound region is experiencing a record “episodic tremor and slip” event, according to the Pacific Northwest Seismic Network.

Parents, if nobody is watching the TV, please turn it off.

Researchers who conducted a national survey of kids' exposure to TVs droning on in the background say, "The amount of exposure for the average child is startling."

How much is it, exactly? Try just under four hours a day for the typical kid.

Do you bite your nails? For 30 years, I did. We nail biters can be "pathological groomers" — people for whom normal grooming behaviors, like skin picking or hair pulling, have become virtually uncontrollable.
