Sardines, herring and other small fish species are the foundation of the marine food web — they're essential food for birds, marine mammals and other fish. But globally, demand for these so-called forage species has exploded, with many going to feed the livestock and fish farming industries.

"Discuss, monitor, and educate."

That's Kortney Peagram's advice to parents and teachers who want to help special needs teens lead an online life. She wrote up some of her experiences as a psychologist working to reduce cyberbullying in Chicago for our friends at NPR's All Tech Considered.

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.

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."

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.

The NFL has struck a deal with Twitter to live-stream, for free, the 2016 season of Thursday Night Football online through the social media site.

For the NFL, this is a push to reach the growing cohort of people who might not have a cable subscription. For Twitter, it might prove to be a major win in its ongoing challenge to attract and keep new users.

A giraffe born at the Santa Barbara Zoo has died in Ohio.

Santa Barbara Zoo officials said Asha, one of the zoo's Masai giraffes, had to be euthanized Sunday.

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.

Heat Storage: Molten Salt And A Giant Solar Farm

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

In Chicago, one neighborhood's rat problem is about to get a lot worse.

Crews are preparing to tear down an old hospital and when the wrecking ball starts swinging, the rodents living in and underneath the aging structure will scurry.

The city and the developer are setting poison baits and traps to help control the problem, but some residents are turning to one of the rats' worst enemies instead — cats.

Construction On Old Buildings Worsens Rat Problem

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.

ARI SHAPIRO, HOST:

Virtual reality headsets have finally hit the consumer market. We wondered when that phrase - virtual reality - first showed up on NPR. It's the perfect candidate for our series...

As a bullying counselor, I spend many of my days helping students and teachers handle confrontational behavior — or, as the kids say, drama. But this was a peculiar situation.

It started, as bullying often does, in a school hallway. E says she overhead A talking about her. (Editor's note: Only the girls' first initials are being used to protect their identities, given the sensitivity of the subject.)

This week's most adorabull story begins with a dream:

Gutsy cow bolts from slaughterhouse, goes to college.

That was the headline from Fox News, introducing the inspiring tale of an animal doomed to turn into dinner, but chasing a dream of higher education.

Or, OK, a bovine that just happened to spring from captivity near a college campus in Queens, New York.

#NPRreads is a weekly feature on Twitter and on The Two-Way. The premise is simple: Correspondents, editors and producers from our newsroom share the pieces that have kept them reading, using the #NPRreads hashtag. Each weekend, we highlight some of the best stories.

What would you consider "the best selfie ever"?

A shot of yourself alongside the pope, the president, Angela Merkel, Lin Manuel Miranda or Steph Curry?

This week Ben Innes, a health and safety auditor from Leeds, Great Britain, used those words to send out a photo in which he posed with the man who hijacked his plane.

The hijacker has what looks like a suicide vest of explosives strapped to his chest. Ben Innes is grinning.

Prosthetic limbs for people who have lost an arm or a leg have come a long way in the past decade. They are now lighter and more comfortable and flexible. You can change out a prosthetic foot for a ski, an ice skate, or a "cheetah foot" for high-performance running.

Athletes and a new generation of wounded warriors from Iraq and Afghanistan are also changing the way wearers feel about the prosthesis — pride is replacing stigma.

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.

The Federal Communications Commission is officially proposing to begin regulating how Internet service providers handle user privacy. The agency is looking to restrict the companies' ability to share with advertisers and other third parties the information they collect about what their customers do online.

A lone hunter stealthily stalking its prey; a shrill cry in the night.
