Scientists have answered a burning question central to the charm of sunflowers: Why do young flowers move their blooms to always face the sun over the course of a day?

And then: Once sunflowers reach maturity, why do they stop tracking the sun and only face east?

Bill Radke speaks with KUOW's environmental reporter Ashley Ahearn about the growing debate around oil trains traveling through Washington state and why we are in the crosshairs for even more trains carrying crude oil from the Bakken Shale in North Dakota.

Bill Radke speaks with author Ana Maria Spagna about the natural beauty of the North Cascades National Park in Washington. This year marks the 100th anniversary of the National Parks Service. Spagna has lived and worked in the North Cascades for the past 15 years.  

Nestle’s plans to build a commercial water bottling plant in another Northwest town is stirring up more controversy. Waitsburg, Washington's mayor resigned this week amid accusations of backroom deals and protests of the plan by many area residents.

Nestle wants to build a water bottling plant in the Northwest. It first looked to Cascade Locks, Oregon, but voters in Hood County effectively blocked that plan.

If you live in an apartment complex in the greater Seattle area, you might open your door this summer and find a pair of college students in green polos on your front step. They won’t try to get you to vote, buy their wares or convert you. They just want you to recycle.

Russia is fighting a mysterious anthrax outbreak in a remote corner of Siberia. Dozens of people have been hospitalized; one child has died. The government airlifted some families out because more than 2,000 reindeer have been infected.

Officials don't know exactly how the outbreak started, but the current hypothesis is almost unbelievable: A heat wave has thawed the frozen soil there and with it, a reindeer carcass infected with anthrax decades ago.

Some scientists think this incident could be an example of what climate change may increasingly surface in the tundra.

It's a warm, sunny morning at the Homestead National Monument of America in southeastern Nebraska. A burn crew dressed in yellow and green flame-resistant clothing is about to set a patch of tall-grass prairie on fire — on purpose.

U.S. Sen. Ron Wyden says Canada is tipping the scales for its lumber companies by undercharging them for publicly-owned timber.

As a result, the Oregon Democrat says, Canadian companies have an unfair advantage over U.S. lumber producers — especially in the Northwest.

But Canadian leaders disagree. The two countries have fought over the issue for decades. They’re currently renegotiating a 2006 agreement that expired last year.

I did a little experiment the other day. I stood outside a Whole Foods Market in Washington, D.C., with two cartons of large brown eggs. One carton had the words "Non-GMO Project Verified" on it, with a little orange butterfly. It also said cage-free. The other carton had a different label; a green and white circle with the words "USDA Organic." One other crucial difference: the organic carton cost 50 cents more.

I asked shoppers which carton they would buy.

Tuesday’s high winds set two major new fires raging in Washington state. One ripped across grassy eastern Washington flats near Moses Lake and the other up a steep canyon near the Snake River and Pullman.

The Range 12 Fire in southeast Washington has destroyed some of the most sensitive shrub steppe habitat in the nation.

Officials from the Hanford nuclear reservation and Energy Northwest have been meeting with fire managers in southeast Washington state Tuesday. The nearby Range 12 Fire has grown to more than 177,000 acres and high winds are predicted this evening.

The farm-to-table movement has caused oyster farming on the East Coast to double in the past six years, and the industry has shown no signs of slowing. But not only is the mollusk's mighty comeback good for consumers and fishermen — it's also good for waterways.

Jimmy Parks, longtime chef and owner of the Butcher Station in Winchester, Va., says the way we eat oysters has changed in the past decade.

Washington environmental regulators will soon find out if their new water-quality rule is good enough for the Environmental Protection Agency.

The fish consumption rule, as it’s called, sets tougher limits on how much toxic pollution cities and businesses can discharge into lakes, rivers and marine waters.

Crews Say Drones Hamper Firefighting Efforts

Aug 1, 2016

A wildfire in southeast Washington has grown to 70,000 acres between Yakima and the Tri-Cities. More than 100 crew members are working to keep the Range 12 Fire from spreading.

But they say something could slow that work down: drones.
