Science + Technology

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 Communication suggests 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:

Beyond The Keyboard And Mouse

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.
