A magnitude 5.0 earthquake shook central Oklahoma on Sunday evening, damaging several buildings. Multiple aftershocks also hit the area, the U.S. Geological Survey says.

The quake epicenter was about a mile west of the town of Cushing, the largest commercial crude oil storage center in North America and the southern terminus of the Keystone pipeline.

When electric cars began to take hold in the U.S. market — a small hold — the big concern was range anxiety: the fear that your vehicle doesn't have the fuel to get to your destination.

Whether it's an IUD, a shot, an implant, or a daily pill, birth control is a regular part of many adult women's lives. It has left a lot of women asking: Why not men?

There's a seductive idea, currently being road-tested, for how to stop the world's forests from disappearing. It relies on big food companies.

That's because most forests are being cleared in order to grow crops or graze cattle. And the resulting palm oil, soybeans or beef find their way into foods being sold by a relatively small number of global companies.

So here's the strategy: Get those companies to boycott products from deforested land, and much of the economic incentive to clear more forests will disappear. This should slow down or even stop the loss of forests.

Last month, Australian surfer Jade Fitzpatrick sustained three bite wounds to his thigh from a great white shark as he waited for a wave on his surfboard off the north coast of New South Wales.

As the Guardian newspaper reported, he was helped out of the water by a friend, received medical treatment and planned to surf again in the same waters within 10 days.

Alaska's Bureau of Land Management regularly posts photos and videos of flying squirrels, scampering porcupines, majestic moose or dramatic landscapes.

But the video that went up last week was different. It was ominous. It was mysterious. It was ... the Chena River Ice Monster, as captured by a baffled BLM employee.

The video shows a strange, undulating icy shape appearing to move through the water. The video has a dramatic soundtrack and an overlay of a camcorder, but BLM insisted the footage itself was unedited.

A new study suggests some Los Angeles-area earthquakes in the 1920s and 1930s could have been caused by the oil boom at the time.

The paper, scheduled to be published online Tuesday in the Bulletin of the Seismological Society of America, presents evidence that drilling around Los Angeles between 1915 and 1932 could have been associated with damaging earthquakes in the area, including the magnitude 6.4 Long Beach quake in 1933 that killed 120 people.

A large space rock came fairly close to Earth on Sunday night. Astronomers knew it wasn't going to hit Earth, thanks in part to a new tool NASA is developing for detecting potentially dangerous asteroids.

After years of negotiations, nations have reached an agreement to establish the world's largest marine sanctuary in Antarctica's Ross Sea.

Twenty-four countries and the European Union reached the unanimous deal at an international meeting of the Commission for the Conservation of Antarctic Marine Living Resources in Hobart, Australia on Friday.

If you want to feel virtuous the next time you chug a brewski, consider the Long Root Ale. This new beer, mildly fragrant and with a rye-like spiciness, is the first to use Kernza, a kind of wheat that could make agriculture more sustainable, especially in the face of climate change.

In 1950, less than 50 percent of the world's population lived in cities.

As of 2014, more than half of people on Earth occupied space in urban areas. By 2050, it is expected that the city dwellers will grow to 66 percent.

The tipping point has been crossed. More important, our rapid urbanizing comes at exactly the same moment the planet begins its transition to a new (and unknown) climate state.

When scientists recently announced that they had discovered a new planet orbiting our closest stellar neighbor, Proxima Centuri, they also released an artist's conception of the planet.

An experimental lander from the European Space Agency is making its final descent toward Mars, preparing for a controlled landing on Wednesday.

The Schiaparelli probe detached from its mothership, the Trace Gas Orbiter, on Sunday.

Counting all the galaxies in the universe is hard. So hard, it seems, that it's possible to miss billions of them.

A new analysis of Hubble Space Telescope data finds there are almost 10 times more galaxies in the universe than we once thought there were — about 2 trillion of them, up from about 200 billion.

In the world of illegal wildlife trade, the most valuable appendage — even more than elephant ivory — is the horn of the rhinoceros. Investigative journalist Bryan Christy estimates that the wholesale market for rhino horn is roughly a quarter of a billion dollars.

The teenage brain has been characterized as a risk-taking machine, looking for quick rewards and thrills instead of acting responsibly. But these behaviors could actually make teens better than adults at certain kinds of learning.

Human life spans have been increasing for decades thanks to advances in treating and preventing diseases and improved social conditions.

In fact, longevity has increased so much in recent decades that some researchers began to wonder: What is the upper limit on human aging?

I start with a remarkable quote:

Some cutting-edging science today relies on the centuries-old art of glassblowing.

When researchers in chemistry, physics and medicine need special glass tools for complex experiments, they sometimes sit down with a glassblower to sketch out designs for customized beakers, flasks and condenser coils.

The largest radio telescope in the world officially opened on Sunday, according to China's official Xinhua News.

When the phone rang, Rebecca Richards-Kortum thought it was a telemarketer. Instead, it was the MacArthur Foundation calling her at home to tell her she'd just won a grant totaling $625,000. And she hadn't even been aware that she'd been nominated for the prestigious award.

A scientist in Sweden has started trying to edit the DNA in healthy human embryos, NPR has learned.

The step by the developmental biologist Fredrik Lanner makes him the first researcher known to attempt to modify the genes of healthy human embryos. That has long been considered taboo because of safety and ethical concerns.

Five people. Ten bears. One desperate call for help.

On a remote Arctic island, five researchers at a weather station found themselves "besieged" by polar bears over the weekend, Russia's TASS news agency reports.

Vadim Plotnikov, the head of the weather station on Troynoy Island, told the news agency on Monday that the staff there had seen 10 adult bears around the station, as well as several cubs.

Two weeks ago, a polar bear ate one of the weather station's two dogs — and hadn't left the station since.

This election season, voters should be evaluating the presidential candidates' attitudes toward science.

ScienceDebate.org proposes a set of 20 science and science policy questions for all candidates, suggesting that "science impacts voters at least as much as the economic policy, foreign policy, and faith and values candidates share on the campaign trail."
