It was the first — and only — time Dr. Naveed Khan, a 35-year-old radiologist, ever rode in an all-terrain vehicle.

Khan took the wheel from his friend and drove circles in the sand, on a trail along the Red River in Texas.

"As soon as I turned to the side where my body weight was, this two-seater vehicle ... just tilted toward the side and toppled," Khan recalled. It landed on his left arm.

Officials from 14 states' top legal offices and the Justice Department have begun a coordinated conversation about ways to keep tabs on — and potentially rein in — the fast-growing tech giants.

A scientist in Australia has come up with an insecticide-free way to control a particularly pesky species of mosquito.

The approach involves two things: deploying a decidedly low-tech mosquito trap called a GAT and getting to know your neighbors.

GAT stands for Gravid Aedes Trap. Aedes is short for Aedes albopictus, known colloquially as the Asian tiger mosquito, which bites aggressively night and day.

Instagram Co-Founders To Step Down

Sep 25, 2018

Kevin Systrom and Mike Krieger, co-founders of Instagram, have announced their plan to leave the company that produces the popular photo-sharing application.

"We're planning on taking some time off to explore our curiosity and creativity again," Systrom said in a statement on the company's website. "Building new things requires that we step back, understand what inspires us and match that with what the world needs; that's what we plan to do."

Starting this semester, the Colorado School of Mines is offering the world's first degree programs in Space Resources — essentially mining in outer space.

It's not just academic institutions like the School of Mines taking note; a small but growing number of startups expect this to be very big business sooner than a lot of us might think.

From the ramp tower 120 feet above the runway, it's clear Philadelphia International Airport is surrounded by water. There is wetland, a network of creeks and, just a couple hundred yards away, the tidal Delaware River leading out to the bay. As with many airports, the original idea was to build on a large tract of land convenient to a city but far enough away from homes and tall buildings. Often, that meant coastal wetlands and landfill.

Now, such airports are threatened.

A federal judge has restored Endangered Species Act protections for grizzly bears living around Yellowstone National Park.

In his ruling, U.S. District Court Judge Dana Christensen said the federal government didn't use the best available science when it removed the bears from the threatened-species list last year.

Monday's ruling puts a stop to proposed grizzly hunts in Wyoming and Idaho, which were on hold while Christensen mulled his decision.

The National Park Service has embarked on a three- to five-year plan, in collaboration with the Washington Department of Fish and Wildlife and the National Forest Service, to remove all mountain goats from Olympic National Park in Washington state.

As part of that plan, more than 75 mountain goats arrived in Washington's North Cascade mountains by refrigerated truck — to keep the goats cool — in recent weeks, before they were transferred to helicopters for the ride of their lives.

For the first time, scientists have demonstrated that a controversial new kind of genetic engineering can rapidly spread a self-destructive genetic modification through a complex species.

NPR is looking at when and why obstetricians and gynecologists put their patients on bed rest. If you've been pregnant in the past year and were advised to stay on bed rest, we would like to hear from you.

If you've ever tried to ripen a piece of fruit by sticking it in a bag with a banana, you've harnessed the power of ethylene.

Ethylene is an important plant hormone. In bananas and many other fruits, production of ethylene surges when the fruit is ready to ripen. This surge triggers the transformation of a hard, green, dull fruit into a tender, gaudy, sweet thing that's ready-to-eat.

The empty field behind Mahlodumela primary school in Chebeng village doesn't look like much. It's an anonymous stretch of scrubby grass, punctuated by a lonely metal goal post.

But what happened in this field in 2014 sparked a debate in South Africa that is still simmering today. That January, Michael Komape, a 5-year-old student who had just started school three days earlier, wandered out to the field to use the school toilet.
