A new Rembrandt painting unveiled in Amsterdam Tuesday has the tech world buzzing more than the art world.

That's because the painting is the creation of a 3-D printer — and not the Dutch master Rembrandt van Rijn himself, who has been dead for almost 450 years.

Residents of Flint, Mich., may tell you lead is a serious menace, but for most of the last 5,000 years, people saw lead as a miracle metal at the forefront of technology.

"You can think about lead as kind of the plastic of the ancient world," says Joseph Heppert, a professor of chemistry at the University of Kansas. He says it was because lead is easy to melt — a campfire alone can do it. Unlike iron, lead is malleable.

Scientists have discovered a supermassive black hole that may be the biggest ever spotted — and its location in a ho-hum group of galaxies suggests that cosmic monsters like this one might be more common than astronomers previously thought.

In the 1940s, an elite team of mathematicians and scientists started working on a project that would carry the U.S. into space, then on to the moon and Mars. They would eventually become NASA's Jet Propulsion Laboratory (or JPL), but here's what made them so unusual: Many of the people who charted the course to space exploration were women.

Nathalia Holt tells their story in her new book, Rise of the Rocket Girls: The Women Who Propelled Us, from Missiles to the Moon to Mars. Holt tells NPR's Ari Shapiro that the women worked as "computers."

A panel of ocean scientists from Washington, Oregon and California said Monday that local action on the West Coast — one of the regions of the world hardest hit by ocean acidification — could soften the blow of this rapidly worsening global problem.

Americans throw away about a third of our available food.

But what some see as trash, others are seeing as a business opportunity. A new facility known as the Heartland Biogas Project is taking wasted food from Colorado's most populous areas and turning it into electricity. Through a technology known as anaerobic digestion, spoiled milk, old pet food and vats of grease combine with helpful bacteria in massive tanks to generate gas.

Renewable energy like solar and wind is booming across the country as the costs of production have come down. But the sun doesn't always shine, and the wind doesn't blow when we need it to.

This challenge has sparked a technology race to store energy — one that goes beyond your typical battery.

Batteries are often used to store solar power, but it can be a costly endeavor.

Bill Radke speaks with Lisa Stiffler, author of a GeekWire series following eight women who joined the tech workforce twenty years ago. Stiffler was interested to learn how the women made their way in an industry dominated by men.

When the FBI tried to force Apple to unlock an iPhone last month, it was a battle of titans. There were high-powered lawyers and dueling public relations strategies. But when police encounter a privacy technology run by volunteers, things can be a little different.

If you've been following any of the big news stories on food fraud lately, you'll know that it's tough to know what exactly is in our food — and where it's been before it makes it onto our dinner plates.

Critics call them "parachute researchers": Scientists from wealthy nations who swoop in when a puzzling disease breaks out in a developing country. They collect specimens, then head straight back home to analyze them. They don't coordinate with people fighting the epidemic on the ground — don't even share their discoveries for months, if ever.

Sometimes it's because they want to publish their results – and medical journals prefer exclusives. And sometimes it's because they can make a lot of money by coming up with copyrighted treatments for the disease.

Malware Attacks On Hospitals Put Patients At Risk

The first sign seems innocuous enough if you don't know what you're looking at: Files in the computer appear as decrypt.html, or decrypt.txt instead of their usual names.

Then, you click. A box pops up that gives you an ultimatum: Want the file? You'll have to pay up, and probably in bitcoin.

Finding people's homes in Nigeria is a nightmare.

ZIP codes don't exist. House numbers are random. In poorer areas of the city, there's no such thing as urban planning. Houses are built wherever people can find a plot of land, for example. And many parts of the city aren't mapped out on GPS. Then, of course, there's the traffic.

Tesla, the maker of electric vehicles, Thursday night unveiled its mass-market Model 3. The car is expected to have a range of 215 miles at a base price of $35,000 ($27,500 after federal tax credits).

Tesla CEO Elon Musk told a crowd of loyal fans in Hawthorne, Calif., he is "fairly confident" the vehicle will go on sale in 2017. That the assembled crowd laughed at the statement is a sign of the near-cult following Tesla (and Musk) enjoy.

By 10 p.m. PDT, the company had received 140,000 advance orders, according to Musk, for a car almost no one had seen.
