The moon seemed to take over the sun, shrouding parts of South America and the southern Pacific in complete darkness — during the day.

The path of Tuesday's total solar eclipse included Chile and Argentina, where people brought out special glasses, and even suits (you'll see those below), to witness the celestial show.

The eclipse path also fell on scientific facilities such as La Silla Observatory in Chile and the Cerro Tololo Inter-American Observatory, also in Chile.

A young female fox, just shy of her first birthday, stunned scientists by covering an unbelievable distance during a short, four-month trek. The animal, also known as a coastal or blue fox, traveled more than 2,700 miles from Spitsbergen, the largest island of the Svalbard Archipelago of Norway, to Ellesmere Island in Nunavut, Canada. The journey is among the longest dispersal events ever recorded for the species.

A San Francisco fertility clinic says that a problem with the liquid nitrogen in one of its storage tanks may have damaged thousands of frozen eggs and embryos, triggering calls and letters to more than 400 concerned patients of the Pacific Fertility Center.

One shred of solace that surfaced as hurricanes and tropical storms pummeled Texas, Florida and Puerto Rico last fall was the opportunity to see drones realize some of their life-saving potential.

There is no shortage of speculation on what became of legendary American aviator Amelia Earhart, who disappeared in 1937 over the Pacific during an attempt to circumnavigate the globe.

Now, Richard Jantz, a researcher affiliated with the University of Tennessee, has re-examined data from bones found on a remote atoll three years after Earhart vanished and has determined they very likely belonged to her.

Three main theories about Earhart's disappearance — arguably the most enduring aviation mystery in history — have been bandied about over the years.

Over the past few years, I've spent many hours reading up on — and a morning observing — the smart, sassy behavior of octopuses.

The U.S. is on track to become the world's biggest oil producer, pumping out more crude than at its peak nearly a half century ago. For decades, few expected such a comeback, and it's all the more remarkable because the price of a barrel of oil is nowhere near what it was during the last, recent boom.

"This is an incredible statement, but we're probably making more money at fifty dollars a barrel than a hundred," says Kirk Edwards, president of Latigo Petroleum in Midland, the de facto oil capitol of West Texas.

Technology is threatening a lot of jobs — travel agents, truck drivers, factory workers. But here's one you might not expect: actors.

Technology in the entertainment business is on course to create digital actors who compete with live ones.

On winter days when the weather is good, a research plane takes off from St. Simons, a barrier island in Georgia. Pilots from the National Oceanic and Atmospheric Administration fly straight lines out and back along Georgia's Atlantic coast, covering hundreds of miles of open ocean. Riding in the plane, surveyors are glued to the window scanning the water for North Atlantic right whales.

Artists and criminals are often the first to push the boundaries of technology. Barrett Brown is a criminal who has actually helped inspire art — the TV show Mr. Robot. Its protagonist is a hacktivist — a hacker who breaks into computer systems to promote a cause.

Brown was connected to Anonymous, a group that hacked a private security firm to reveal secrets. He is now out and living in a halfway house in Dallas.

Seventy percent of the world's king penguin population could face threats to its habitat by the end of this century, according to a new scientific model.

The researchers say the problem is that the animals' primary source of food is moving farther away from places where the penguins can breed. They're very likely going to have to swim farther for their dinner.

We spend a lot of time talking to Alexa and Siri. Imagine if such artificial personalities were put inside a cute, adorable robot. That's what Alexander Reben has done. The artist created what he saw as the perfect interview machine to see how much he could get people to reveal to the robot.

SpaceX successfully launched its Falcon 9 rocket Thursday morning.

But the hard part came next: trying to catch the rocket's falling nose cone with a big net on a ship in the ocean.

Wait, what?

I've got a degree in physics, but I have not stepped inside a laboratory since I graduated from Oxford.

A couple of years ago, at the peak of my children's reluctance to eat vegetables, I decided to try an experiment.

When the kids arrived home from daycare one afternoon, I had bowls of colorful vegetables cut up and ready to go: crunchy red and yellow peppers, bushy little florets of broccoli, tomatoes and mushrooms and olives. I gave them each a cheese pizza base to "decorate" for dinner, and they gleefully complied. My older daughter made a face with olive eyes, broccoli hair, and a bright, red-pepper mouth. My younger daughter loaded on veggies by the fistful.

NASA's IMAGE spacecraft spent five years studying the Earth's magnetosphere, but when its signal blinked off in 2005, the space agency called it a mission and moved on.

If Victorians were offended by Charles Darwin's claim that we descended from monkeys, imagine their surprise if they heard that our first ancestor was much more primitive than that, a mere single-celled creature, our microbial Eve.

Say hello to an orca, and it might say hello back — or at least try to.

An international team of researchers, working with two orcas at an aquarium in France, have found that the whales were able to replicate the sounds of human speech, including words like "hello" and "bye-bye," as well as series of sounds like "ah ah."

Scientists have found specialized brain cells in mice that appear to control anxiety levels.

The finding, reported Wednesday in the journal Neuron, could eventually lead to better treatments for anxiety disorders, which affect nearly 1 in 5 adults in the U.S.

Early Wednesday morning brought a lunar event that hasn't been seen since 1866.

It was at least partially visible in all 50 U.S. states, though the views were better the farther west you live.

Let's break this down. This event – called a super blue blood moon – was actually three fairly common lunar happenings all happening at the same time.

And scientists say that information gathered during the event could help them figure out where to land a rover on the moon.

The impacts of climate change aren't a far-off possibility for the Pacific shellfish industry. Acidifying seawater is already causing problems for oyster farms along the West Coast and it's only expected to get worse.

That has one Bay Area oyster farm looking for ways to adapt. It's teaming up scientists who are studying how the local ecosystem could lend a helping hand.

"We need help," says Terry Sawyer of Hog Island Oyster Company. "That 'canary in a coalmine' analogy drives me crazy, but that's what we are."

For more than four decades, she didn't have a name. Since 1975, when her mummified body was unearthed in a church in the Swiss city of Basel, she had been a scientific mystery — a well-preserved corpse buried with proofs of her wealth, who for lack of identification took on a distinguished title: the Lady from Barfüsser church.

Archaeologists in Israel have discovered the oldest fossil of a modern human outside Africa. The fossil suggests that humans first migrated out of the continent much earlier than previously believed.

Last summer, Zac Peterson was on the adventure of a lifetime.

The 25-year-old teacher was helping archaeologists excavate an 800-year-old log cabin, high above the Arctic Circle on the northern coast of Alaska.

They had pitched tents right on the beach. Over the course of a month, Peterson watched a gigantic pod of beluga whales swim along the beach, came face-to-face with a hungry polar bear invading their campsite and helped dig out the skull of a rare type of polar bear.

But the most memorable thing happened right at the end of the trip.

Chinese researchers have finally figured out how to clone a primate, using the same technique Scottish researchers devised to clone the first mammal, Dolly the sheep, in the mid-1990s.
