If you’ve been to downtown Seattle, you’ve probably seen people talking to themselves on street corners, or shouting at strangers. Now there’s a fresh face trying to help those in psychiatric crisis.

He’s a roaming mental health counselor, hired by the Union Gospel Mission and downtown’s business-funded Metropolitan Improvement District.

On Mars, Curiosity took a moment or two for self-identification, as if to say, this is me on Mars. The composite image however, almost looks as if Curiosity had a visitor.

I've been hearing strange wind stories all my life. The best ones are both wildly improbable but still true, like how the Empire State Building gets hit by wafts of barley flying in on jet streams from Iowa, or how tons of sand from the Saharan desert rain down every year onto Brazilian rainforests. You never know what the wind will bring. The wind decides.

Scientists say an Asian elephant at a South Korean zoo can imitate human speech, saying five Korean words that are readily understood by people who speak the language.

The male elephant, named Koshik, invented an unusual method of sound production that involves putting his trunk in his mouth and manipulating his vocal tract.

"This is not the kind of sound that Asian elephants normally make, and it's a dead-on match of the speech of his trainers," says Tecumseh Fitch of the University of Vienna in Austria.

If you have a condition or injury that leaves you in non-stop pain, for months or years, your doctor might prescribe a powerful painkiller, such as Vicodin or OxyContin. Many doctors are looking for alternatives to these narcotics, and they're sharing approaches this week at a “National Opioid Summit” in SeaTac. 

Concerns about painkillers are rising, because abuse, addiction and overdose deaths are up.

How rare is the Earth? Kepler satellite sheds light

Oct 31, 2012

Now that we are fairly sure that there are many Earth-like planets in our galactic neighborhood, the time is ripe (or almost so) to wonder whether these new worlds do indeed have a high probability of hosting new forms of life.

Science and religion alike grapple with some of our deepest questions: What is the purpose of life? Why is the natural world just so? Why does the biological world strike us as so exquisitely designed?

Peter Remine says he will know it's time to get serious about rights for robots "when a robot knocks on my door asking for some help."

Remine, founder of the Seattle-based American Society for the Prevention of Cruelty to Robots, says the moment will come when a robot in an automobile factory "will become sentient, realize that it doesn't want to do that unfulfilling and dangerous job anymore, and ask for protection under state workers' rights."

Some of the weirdest animal behavior is about romance. That's especially true with birds — they croon or dance or display brilliant feathers to seduce the reluctant.

This sort of sexual display apparently has a long pedigree: There's now new evidence that some dinosaurs may have used the same come-on.

The source is a kind of dinosaur that was built like a 400-pound ostrich. It lived about 75 million years ago and is called ornithomimus, meaning "bird mimic."

"Frankenstorm" may be drawing the attention of meteorologists here on Earth.

But NASA scientists using the Cassini spacecraft have witnessed a rare massive storm on Saturn that was so violent it sent the temperature in the planet's stratosphere soaring to 150 degrees Fahrenheit above normal.

Far from the campaign trail, President Obama’s health-care law is chugging toward implementation in Washington state. A new agency is emerging, with a new name – and some questions about how to fund it.

In a blast from the past, the public radio show Bullseye dug up Seattle’s connection to the first video showing the genesis of computer-generated images or graphics in movies.

In 1980, Boeing employee and University of Washington graduate Loren Carpenter presented a two-minute computer generated movie call “Vol Libre” that almost immediately revolutionized moviemaking.

It's not the sexiest of weapons, because it doesn't cause big explosions, or fly around the world in minutes. But the effect is huge and could cripple a modern military without causing any casualties.

This week, Boeing announced that it has successfully tested a missile that can send out targeted, high-power microwaves that fry electronics without actually causing an explosion.

If you're reading this blog, you're probably into food. Perhaps you're even one of those people whose world revolves around your Viking stove and who believes that cooking defines us as civilized creatures.

Well, on the latter part, you'd be right. At least according to some neuroscientists from Brazil.

Whales are among the great communicators of the animal world. They produce all sorts of sounds: squeaks, whistles and even epic arias worthy of an opera house.

And one whale in particular has apparently done something that's never been documented before: He imitated human speech.

The beluga, or white whale, is smallish as whales go and very cute, if you're into marine mammals. Belugas are called the "canaries of the sea" because they're very vocal.

You can do just about anything with your phone these days. Take an electrocardiogram. Confess your sins. Even smoke a cigarette

Instead of increasing kids’ isolation, a new study from the University of Washington suggests life on the digital frontier is helping kids reach developmental milestones.

Phones and social media help kids share personal problems and build a sense of belonging, the UW noted in a press release.

A Chinese scientist recently suggested that prehistoric humans ate pandas. The evidence, based on cut marks on panda bones, strikes me as thin, but the report led me to a thought experiment.

How would people in the modern world react if the some population or subculture today made panda-foraging a goal? I imagine most of us would be horrified, and not only because the panda is an endangered species. The panda has become a symbol of cuteness, an animal we love to love.

Treatment for Alzheimer's probably needs to begin years or even decades before symptoms of the disease start to appear, scientists reported at this week's Society for Neuroscience meeting in New Orleans.

"By the time an Alzheimer's patient is diagnosed even with mild or moderate Alzheimer's there is very, very extensive neuron death," said John Morrison of Mount Sinai Medical School in New York. "And the neurons that die are precisely those neurons that allow you to navigate the world and make sense of the world."

Lately, we've been learning more and more about the teeming masses of bacteria inside our bodies - essentially trillions of tiny organisms that make us sick and keep us healthy.

Now two scientists at the University of Colorado have dared to ask what kinds of bacteria lives inside our mouths. And they're finding some pretty surprising things in there.

Nerds, rejoice! It's Nobel season — the Oscars for lab rats, peacemakers and cognoscenti alike. Every fall, big thinkers around the world wait for a middle-of-the-night phone call from Sweden, dreaming of what they might do with the $1.2 million prize.

Tell us you can resist clicking on this headline from Florida's Sun Sentinel:

"Huge Eyeball From Unknown Creature Washes Ashore On Florida Beach."

It's big, it's blue and the newspaper says "among the possibilities being discussed are a giant squid, some other large fish or a whale or other large marine mammal."

The Florida Fish and Wildlife Conservation Commission has sent the eye off for study.

For one thing, Kennewick Man – the 9,500-year-old remains found in the shallows of the Columbia River more than 16 years ago – was buff. We’re talking beefcake.

So says Doug Owsley, head of physical anthropology at the Smithsonian’s National Museum of Natural History. Owsley led the study of the ancient remains.

Scientists have discovered a world much fancier than our homely, little Earth.

New research that will published in the journal Astrophysical Journal Letters details a planet that is eight times heavier than Earth and with twice its radius. But instead of being covered in water and granite, it is encrusted in graphite and diamond.

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.
