A group of chemicals called PFAS are common in firefighting foams, as well as household products like rain jackets, pizza boxes and non-stick pots and pans. They've been in use since the 1940s and have come to be known as "forever chemicals" because they persist in the environment.

PFAS, which stands for per- and polyfluoroalkyl substances, have made their way into watersheds around the world, and as a recent study found, even into raindrops. Some are considered a threat to human health. 

Researchers including Jens Blotevogel, an environmental engineer at Colorado State University, are studying ways to get rid of the compounds. 

Nationwide, more and more people are surviving childhood. But researchers found those improvements might not be as big in rural areas. 

A report last year found that child mortality rates had improved. In fact, nationally, it looked like the country had met its 2020 goals. But then researchers took a closer look.

Researchers from a number of states, including Idaho, Colorado and Nevada, have found that grazing does not help get rid of cheatgrass, a highly flammable weed. 

There’s wide variability in state policies about what care to give to women who are pregnant and behind bars. That’s according to a new report from the Prison Policy Initiative, a research and advocacy organization focused on mass incarceration.

“Women's populations in prisons have been growing faster than men's for quite awhile now,” said Wanda Bertram, a spokesperson with the Prison Policy Initiative. “So it's a good time to start looking at how women's experiences differ from men's while they're inside.”

Senators from Colorado and Nevada are among those sponsoring a bill aimed at reducing firefighters’ exposure to potentially harmful chemicals. 

Earlier this month the Senate Homeland Security and Governmental Affairs Committee unanimously approved the bill, which aims to protect firefighters from being exposed to a group of chemicals known as PFAS that are found in firefighting foams and gear.

Researchers are looking into what may be a peaceful solution to the timeless struggle against a Mountain West rodent. They’re giving prairie dogs birth control. 

After 25 years of running Ellen's Bed and Breakfast in Longmont, Colo., Ellen Ranson got tired of cooking breakfast.

"So we decided to change the name to Ellen's Bed, Bath & Begone," she says.

That left her more time for sleeping in or reading the paper. But that prospect wasn't too exciting, because the local paper had been thinning out for a while, though Ranson says it used to be relevant.

"And now there's news about Frederick or Erie or Fort Collins or something," she says. All are cities she lives near, but not Longmont.

Instructor Graham Dunne is holding up some printouts with faces on them. He tells his students they're smaller than real heads.

"Here's some useless knowledge from being a sniper," he says. "The average human head is 6 inches across by 10 inches high. These are probably half that."

We're at the Flatrock Regional Training Center in Commerce City, Colorado. Usually the people training here are law enforcement, but today they're teachers, principals, bus drivers, coaches and school administrators — 13 of them.

Update posted June 26, 2019 at 5:48 p.m.: A spokesperson with Clayton Homes says the company has reopened conversations with the Black American West Museum & Heritage Center about the properties they own in Dearfield. "Our hope is to find a way to support their goals while moving ahead with plans to establish affordable housing in the area," said a statement.

About a century ago, African-American settlements sprang up across the West. Now, one of those sites in northern Colorado is set to host new houses.

The Black American West Museum, based in Denver, owns a number of properties in what used to be the town of Dearfield, Colorado. But a national homebuilding company, CMH Homes, Inc., also known as Clayton Homes, is now taking steps to turn other parts of the town into new residences.

A neurodegenerative illness called chronic wasting disease is spreading among deer and elk in our region. Now, researchers at Colorado State University say they’ve found a new way to study the disease -- and another indication that it might eventually become capable of sickening people.

Top politicians are in Vail, Colorado, this week for the annual meeting of the Western Governors Association.

Protesters dressed as swamp creatures kayaked down a river while others marched along a bike path, past private tennis courts and swanky swimming pools outside the hotel where governors met with Interior Secretary David Bernhardt.

“My shirt says keep your oily hands off of Colorado's public lands,” says Chelsea Stencel, who was among the protesters. “David Bernhardt, the ultimate swamp monster.”

The closest that Travis Rupp came to getting fired from Avery Brewing Co. in Boulder, Colo., he says, was the time he tried to make chicha. The recipe for the Peruvian corn-based beer, cobbled together from bits of pre-Incan archaeological evidence, called for chewed corn partially fermented in spit. So, Rupp's first task had been to persuade his colleagues to gather round a bucket and offer up their chompers for the cause.

Chronic wasting disease is crippling deer populations in the Mountain West, around the country and in bordering Canadian provinces. It's not a bacterium or a virus or even a fungus, but caused by something called a prion, a type of protein that all mammals have in their bodies.

Back in March, Zayd Atkinson was picking up trash outside his dorm at Naropa University in Boulder when a group of police officers confronted him, apparently refusing to believe that he lived there.

The spring thaw is upon us, and parched western states will be watching closely as snows melt and rivers rise. Fancy satellites monitor water levels in the biggest rivers, but they don't spot the smaller streams and waterways that feed into them. Now, some Colorado scientists have hit on a new way of tracking those smaller streams — inspired, by Pokemon.
