NPR Science Correspondent Richard Harris traveled to Australia's Great Barrier Reef to find out how the coral reefs are coping with increased water temperature and increasing ocean acidity, brought about by our burning of fossil fuels. Day 2: The good news is life could get better for seaweed.
Picture a coral reef and the first things likely to come to mind are brilliantly colored fish swimming among stout branches of coral. Let your mind wander a bit more and you might imagine some sea turtles, stingrays and sharks.

Basketball fans have one more day to fill out their March Madness brackets. They'll need to predict not just the champions and their route to victory, but also the paths of all the losers. It's not easy. In fact, no person or computer has yet been able to do it.

It looks kinda like a squirrel, except its ears are too small, its tail is ratty, then bushy, and its mouth? Definitely un-squirrel. More like a shrew, a fox, or a dog. And the teeth? Strange. What is it?

You can see it on this Google Map — a little spit of land, sitting between Australia (on the left) and French-governed New Caledonia (on the right).
It's called "Sandy Island." In the Times Atlas of the World it's called "Sable Island." On both maps it's a conspicuous land mass, roughly 15 miles long from north to south, three miles across. Altogether, that's about 45 square miles — about one and a half times the size of Manhattan.

Scientists peering into the atmosphere of a giant planet 130 light years away believe their findings bolster one theory of how solar systems form.
The planet, orbiting the star HR 8799, is part of a solar system containing at least three other "super-Jupiters" weighing in at between five and 10 times the mass of our own Jupiter. The nearby system features a brash, young 30-million-year-old star (by contrast, our Sun is in midlife at about 4.5 billion years old).

Sorry to disappoint, but science writer Carl Zimmer says we're not going to bring back dinosaurs. But, he says, "science has developed to the point where we can actually talk seriously about possibly bringing back more recently extinct species."
It's called "de-extinction" — and it's Zimmer's cover story for National Geographic's April issue.

The new boom in natural gas from shale has changed the energy economy of the United States. But there's another giant reservoir of natural gas that lies under the ocean floor that, theoretically, could dwarf the shale boom.
No one had tapped this gas from the seabed until this week, when Japanese engineers pulled some up through a well from under the Pacific. The gas at issue here is called methane hydrate. Methane is natural gas; hydrate means there's water in it. In this case, the molecules of gas are trapped inside a sort of cage of water molecules.

At its best, the Web is a place for unlimited exchange of ideas. But Web-savvy news junkies have known for a long time that reader feedback can often turn nasty. Now a study in the Journal of Computer-Mediated Communicationsuggests that rude comments on articles can even change the way we interpret the news.
A meteorite that lit the sky over Sri Lanka with a yellow and green flame when it fell to earth on Dec. 29, 2012, contains "fossilized biological structures," according to researchers in Britain, Sri Lanka, and the United States. Elaborating on claims they first made in January, the scientists are also seeking to answer critics who are skeptical of their findings.

Everywhere you walk in downtown Austin, Texas, new names compete for the attention of the tens of thousands wandering the SXSW Interactive festival. Which of this year's emerging ideas and brands — MakerBot, Leap Motion, Geomagic — will break into mainstream consciousness? Here's a quick rundown of the conversation topics in coffee lines, and some notes on appearances and panels that caught our attention:

If you've had wrist and shoulder pain from clicking a mouse, relief may be in sight. This spring, a new motion sensing device will go on sale that will make it possible for the average computer user to browse the Web and open documents with a wave of a finger.
The Leap Motion Controller is on display at the South by Southwest Interactive conference in Austin, Texas, for the first time. It's one of the most talked about startups at the conference, where some 26,000 people have gathered to see emerging tech companies.
Do you know who were the first man and woman in space? How about what makes HIV different than your garden variety case of influenza? And who decided to organize the elements into the periodic table?

When the streaming video service Netflix decided to begin producing its own TV content, it chose House of Cards as its first big project. Based on a BBC series, the show stars Kevin Spacey and is directed by David Fincher, and it has quickly become the most watched series ever on Netflix.
Every year, the South By Southwest music, film and interactive festival gets larger, and navigating the blur of panels, parties and shows gets more daunting. The girth of it all is enough to keep many SXSW old-timers away from Austin this year.

A new study of Central African forest elephants has found their numbers down by 62 percent between 2002 and 2011. The study comes as governments and conservationists meet in Thailand to amend the Convention on International Trade in Endangered Species.
People can get pretty addicted to computer games. By some estimates, residents of planet Earth spend 3 billion hours per week playing them. Now some scientists are hoping to make use of all that human capital and harness it for a good cause.
Right now I'm at the novice level of a game called EyeWire, trying to color in a nerve cell in a cartoon drawing of a slice of tissue. EyeWire is designed to solve a real science problem — it aims to chart the billions of nerve connections in the brain.
Bright lights are part of a city's ecosystem. Think of Times Square or the Las Vegas Strip or right outside your bedroom window.
Electric lighting is ubiquitous in most urban and suburban neighborhoods. It's something most people take for granted, but appreciate, since it feels like well-lit streets keep us safer. But what if all this wattage is actually causing harm?
"We're getting brighter and brighter and brighter," warns Paul Bogard, author of the upcoming book, End of Night: Searching for Natural Darkness in an Age of Artificial Light.

My pal Erik Olsen at The New York Times has just described an extraordinary new way to look at people. You point a camera at someone, record the image and then, using an "amplifier," you can discover things you've never seen before.
