It would normally be easy to miss the dirt road jutting north from a tiny highway near the Arizona-Utah border. But not today, with the long line of cars rumbling toward lonely, rosy cliffs, and an encampment of bird watchers forming under them.

They're all here for four birds.

With a wingspan that can stretch nearly 10 feet, California condors are some of the largest birds in North America. They're also some of the rarest. After the population plunged to just 22 in 1982, all were taken into captivity for safe keeping and breeding.

Gibbon Ridge at the National Zoo is a little less lively this weekend after Muneca, a 51-year-old white-cheeked gibbon, was euthanized on Friday.

Muneca lived a long life for a gibbon, which typically live to be around 30 in the wild. The zoo says that at 51, Muneca was the oldest of her species in the Association of Zoos and Aquariums' Species Survival Plan population.

White-cheeked gibbons are critically endangered and the population decreased by an estimated 80 percent throughout Muneca's lifetime because of loss of habitat.

The venomous fangs of a copperhead snake are one thing. But the recent sighting of a rare two-headed snake in Northern Virginia is alarming — and mesmerizing — both social media spectators and scientists.

Editor's note, Oct. 3, 10:20 a.m.: This story was updated to include additional information about the identity of the marine mammal. Scientists familiar with the area said the animal is a New Zealand fur seal, not a sea lion.

A seal smacks a kayaker with an octopus, and the video capturing the unlikely encounter quickly becomes a viral sensation.

The conflict between man and beasts happened off the coast of New Zealand's South Island.

Facebook says that it has discovered a security breach affecting nearly 50 million accounts and that it's not yet clear whether any information was accessed or any accounts were otherwise misused.

The vulnerability that caused the breach was found Tuesday and was fixed on Thursday night, Facebook says. It was the result of bugs introduced into Facebook's code in July 2017. No passwords or credit card numbers were stolen, the company says.

STEVE INSKEEP, HOST:

Elon Musk, the CEO of the electric car company Tesla, is being sued by the Securities and Exchange Commission, the SEC, all of which started with a tweet. NPR's Jasmine Garsd reports.

Want to see what it would be like to stand on a asteroid? Well, if you were not a human but rather a seven-inch-diameter, just under 3-inch-tall, hopping robot?

A video released Thursday and taken by one of the two bouncing rovers currently on the surface of the asteroid Ryugu — over 200 million miles away from Earth — shows you just this.

The U.S. Securities and Exchange Commission is suing Tesla CEO Elon Musk, alleging securities fraud a month after he announced that he planned to take the publicly traded electric-car company private.

"Musk's false and misleading public statements and omissions caused significant confusion and disruption in the market for Tesla's stock and resulting harm to investors," the lawsuit says.

Millions of years before the brontosaurus roamed the Earth, a massive relative was lumbering around South Africa.

Scientists think this early Jurassic dinosaur was, at the time, the largest land creature ever to have lived. And unlike the even bigger creatures that came later, they think it could pop up on its hind legs.

The Dutch government is considering a proposal to ban the use of smartphones and other "mobile electronic devices" on bicycles.

Infrastructure Minister Cora van Nieuwenhuizen published the draft legislation on Thursday, NL Times reports. If approved, it could go into effect in the summer of 2019.

It is already illegal to use a phone while driving a motor vehicle in the Netherlands, the news site says. Offenders face a fine of more than $250.
