On the Navajo Nation, kids with the most severe developmental disabilities attend a school called Saint Michael's Association for Special Education.

Dameon David, 8, is waking up from a nap in his classroom. He has come to the school in northeastern Arizona for four years. He has cerebral palsy, seizures and scoliosis. His mom, Felencia Woodie, picks him up from a bed with Superman sheets.

Blink while driving on Highway 34, east of Greeley, Colo., and you might miss the former town of Dearfield.

All that's left of the once-thriving town on Colorado's eastern plains are a rundown gas station, a partially collapsed lunch counter and a former lodge. They are the only indication that there was once a community here. The grass around these buildings is crispy and straw-colored, whipped back and forth by relentless winds. The snowcapped Rocky Mountains barely peek through the haze to the west.

Pesticides based on fungi are just one example of biopesticides, a group that also includes bacteria and biochemicals derived from plants.

Biopesticides are a tiny segment of the market for now – but their use is projected to grow at a faster rate than traditional synthetic pesticides over the next few years.

The growth of the organic produce industry is one factor giving biopesticides a boost. So, too, are regulatory hurdles, says Sara Olson, a senior analyst at Lux Research.

It's a cliché that happens to be true: Bears love honey. And in Maryland, lawmakers have passed a bill making it legal to shoot a black bear if it threatens a beekeeper's hive.

In February, state Del. Mike McKay testified before the Environment and Transportation Committee on behalf of the bill. He wore a vest festooned with the image of Winnie the Pooh.

It's been 25 years since the National Academy of Sciences set its standards for appropriate scientific conduct, and the world of science has changed dramatically in that time. So now the academies of science, engineering and medicine have updated their standards.

The report published Tuesday, "Fostering Integrity in Research," shines a spotlight on how the research enterprise as a whole creates incentives that can be detrimental to good research.

About a month after an anti-predator device spit sodium cyanide in the face of an unsuspecting boy and killed his dog, the U.S. Department of Agriculture has announced it is ending its use of the M-44 mechanisms in Idaho indefinitely.

A decades-old tradition unfolded at West Allis Central High on Monday evening - and at schools and courthouses in every county in the state. The Wisconsin Conservation Congress conducted its annual spring hearings.

It's a disorienting year in many democracies, and we are trying to define this moment. Last week, writer Francis Fukuyama talked about democracy in crisis.

President Trump wants America to use more "clean coal" to make electricity. He hasn't elaborated on what kind of coal that might be.

For the second consecutive year, aerial surveys show severe coral bleaching in the Great Barrier Reef off the coast of Australia.

While severe bleaching events have occurred three other times in the past 20 years — in 1998, 2002 and 2016 — this year marks the first time it's known to have happened two years in a row. Scientists say the damage is caused by higher water temperatures due to global warming.

Before we headed out on our latest road trip for the Our Land series, we put a call out on social media, asking for ideas of places we should go in Arizona and New Mexico. Shannon Miller's suggestion really caught our attention: "White Sands are the only white gypsum 'sand' dunes in the world. They are actually crystals and it is beautiful."

How could we resist?

There's really no place like it on the planet: White Sands National Monument in southern New Mexico. It's the world's largest gypsum dunefield, miles and miles of stunning white landscape.

A new study raises a novel idea about what might trigger celiac disease, a condition that makes patients unable to tolerate foods containing gluten.

The study suggests that a common virus may be to blame.

For people with celiac disease, gluten can wreak havoc on their digestive systems. Their immune systems mistake gluten as a dangerous substance.

It has been quite a while since Californians have seen such green. Riding the coattails of an unseasonably wet season, some valleys have become riots of color, deserts have been blanketed with blooms so suffusive they earn the word "super" — and the state's officials have taken notice.
