Quick quiz: In springtime, does snow melt faster out in the open or in the shade? 

You might figure it melts faster in the sunshine, and that seems to be the case for cold climates. But in places with temperate winters, like the Pacific Northwest, it might be just the opposite.

An accidental breakthrough by Washington State University researchers might someday lead to much more powerful computers.

It began when graduate student Marianne Tarun was working with a particular kind of crystal, strontium titanate, in a WSU physics lab. The crystal has strange electrical properties, which interests engineers and computer scientists.

One day she discovered, to her surprise, that something had changed.

Before December, 2012: 

It's a crime to drive under the influence of marijuana if the intoxicant impairs your driving "to an appreciable degree." Prosecutors can use blood analysis, along with other evidence, to prove a person is impaired. But even though marijuana itself is illegal, there's no agreement on what level of THC in the blood constitutes a crime. 

As of December, 2012:

Health officials officials across the Northwest are trying to figure out why they’re seeing a big upswing in the number of people with gonorrhea this year. Washington announced Thursday five counties are in the midst of an outbreak of the infection.

The Washington outbreaks are in Spokane, Benton, Yakima, Kitsap, and Thurston counties. Overall, the state has seen a 34 percent increase in gonorrhea cases over this time last year.

While the brain sleeps, it clears out harmful toxins, a process that may reduce the risk of Alzheimer's, researchers say.

During sleep, the flow of cerebrospinal fluid in the brain increases dramatically, washing away harmful waste proteins that build up between brain cells during waking hours, a study of mice found.

Engineers at the University of Washington have developed a way for some deaf people to enjoy music. The findings could help people with cochlear implants, a bionic inner ear that allows deaf or hearing-impaired people to hear speech, albeit in kind of a robot voice.

Cochlear implants can be a lifesaver for people without hearing, but when it comes to music, this very practical device can’t carry a tune to save its life.

The implants simply aren’t sensitive to pitch and what’s called timbre—the qualities of a sound that make, say, a guitar sound different from a harp.

Telemedicine is rising to new levels of accessibility thanks to the increasing prevalence of smartphones, tablets and webcam equipped computers.

A promising but preliminary new study based on a Seattle scientist's discovery has shown dramatic increases in survival for people with brain cancer.

Charles Cobbs, now head of the Ben and Cathy Ivy Center for Advanced Brain Tumor Treatment at Seattle’s Swedish Medical Center, figured out a key feature of the most common kind of brain tumor, glioblastoma.

The tumor appears to be connected to a virus that most of us carry, called CVM. It’s harmless in most people, but for some, it seems to promote tumor growth.

Two researchers at the University of Washington have managed to pull off something right out of a sci-fi story: one used his brain to control the body of another.

The setup involved two labs on different ends of campus. In one lab sat the receiver, Andrea Stocco, with a device on his head that beams a focused magnetic field into his brain. Across campus, in another lab sat the sender, Rajesh Rao, wearing a cap outfitted with electrodes.

Even the tiniest misprint in a person’s genetic code can cause big health problems, but they can be hard to find. Now members of a team at University of Washington say they’ve designed a better way to track down those mutations.

If you think of DNA as a twisted ladder, each rung is made of two little structures called bases, stuck together. If even one of the billions of these rungs gets copied wrong it can have serious consequences, such as which kind of tuberculosis you get.

Most volcanoes rumble before they erupt, but Washington and Alaska researchers say a big recent eruption was preceded not by a rumble, but a scream.

Alaska’s Mount Redoubt blew its top several times in 2009. Leading up to many of the explosions were a series of little earthquakes—not uncommon for an active volcano. But these quakes began to accelerate, one after another, like a drumbeat building to a climax.

There’s some truth to Washington’s image as a mecca for the physically active. When it comes to exercise, several counties in the state rank in the top 50 out of more than 3,000 counties in the country. But that ranking hides a less flattering trend.

A research idea that was supposed to give people super-powered legs is instead helping stroke patients and other people who can’t walk. 

It’s a new medical device, using a combination of springs, cables, and Velcro. The inventors in Seattle are hoping to transform the possibility of recovery for thousands of people.

The idea started with a horse.

Robots are everywhere these days. They’re working in factories, and are the focus of student competitions. They are also teaching us about nature, especially in the case of robotic fish.

It might seem a little Hollywood to talk about "robo-fish." And as an engineering professor, Kristi Morgansen is a little shy about that.

“We usually call them fish robots, or robotic fish,” she said.

I'll never forget the time my big brother sank his fork in the back of my hand after I snitched food off his plate.

But all siblings fight, right? So I was more than a little skeptical of a study saying that sibling aggression can cause serious mental health problems like depression and anxiety.
