Pacific Northwest Seismic Network

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.

As you take in your next breath of air, you can thank a form of microscopic marine life known as plankton.

They are so small as to be invisible, but taken together, actually dwarf massive creatures like whales. Plankton make up 98 percent of the biomass of ocean life.

"This invisible forest generates half of the oxygen generated on the planet," Chris Bowler, a marine biologist, tells Guy Raz, host of weekends on All Things Considered.

And, as climate change alters the temperature and acidity of our waters, this mysterious ocean world may be in jeopardy.

NASA's Curiosity rover has found definitive proof that water once ran across the surface of Mars, the agency announced today. NASA scientists say new photos from the rover show rocks that were smoothed and rounded by water. The rocks are in a large canyon and nearby channels that were cut by flowing water, making up an alluvial fan.

"You had water transporting these gravels to the downslope of the fan," NASA researchers say. The gravel then formed into a conglomerate rock, which was in turn likely covered before being exposed again.

What would you do if you knew a major earthquake was about to strike in 10 seconds? Some scientists say even a few moments’ warning could save lives, and they’re setting up a system that might soon give Washingtonians time to act before the shaking starts.

On April 11 of this year, an extraordinary cluster of earthquakes struck off Sumatra. The largest shock, magnitude 8.7, produced stronger ground-shaking than any earthquake ever recorded. And it surprised seismologists by triggering more than a dozen moderate earthquakes around the world.

The quakes are also a sign of big changes to come in the Earth's crust.

There's more trouble for your hard-working backyard honey bee. Researchers have confirmed the first cases of "zombee" bees in Washington state and in the Portland area. Infection by a parasite prompts the bees to embark on what's being called a "flight of the living dead."

The initial Washington detection came from an observant beekeeper in the Seattle suburb of Kent.

"The odd thing is they're attracted to light. Bees normally aren't attracted to light. And they're flying at night. Bees don't normally fly at night," says Mark Hohn. He keeps bees as a hobby.

Johns Hopkins, Yale, Harvard, Columbia and Cornell. What do these medical schools have in common?

Beyond their first-rate reputations, they're also on the short list of top U.S. med schools that don't have departments of family medicine. Elite schools have long focused on training specialists and researchers, but with the federal health law's emphasis on primary care, some schools are looking harder at family medicine.

When we think about morality, many of us think about religion or what our parents taught us when we were young. Those influences are powerful, but many scientists now think of the brain as a more basic source for our moral instincts.

Group Health Cooperative says it lost money in August and needs to cut costs.  That will include some layoffs this year. 

It’s not a calamity, says CEO Scott Armstrong, but the trend could lead Group Health to finish the year in the red if it doesn't make changes.

Washington state is not immune from America’s obesity epidemic. A new study looking at where the trends are headed on weight-gain shows half the population headed for obesity by the year 2030. 

Currently, 26.5% of Washington residents are already considered obese. That’s a step beyond overweight, using the standard measurement of body-mass-index (BMI). 

Ever since James Watson and Francis Crick cracked the genetic code, scientists have been fascinated by the possibilities of what we might learn from reading our genes.

Anthropologists believe early humans evolved in Africa and then moved out from there in successive waves. However, what drove their migrations has been a matter of conjecture.

One new explanation is climate change.

Anthropologist Anders Erikkson of Cambridge University in England says the first few hardy humans who left Africa might've gone earlier but couldn't. Northeastern Africa — the only route to Asia and beyond — was literally a no man's land.

Washington banned indoor smoking nearly seven years ago, but one exception survives: hookah lounges.

Local health departments have struggled to shut them down. 

The lounges say they’re private clubs, not public venues, so the law doesn’t apply. They all charge some sort of membership fee, typically about $5.

That defense doesn’t sway health officials, like Frank DiBiase of the Tacoma Pierce County Health Department. His office inspected three hookah bars in Tacoma last year.
