Scientists have unearthed a massive new dinosaur — bigger than a jetliner

Meet Dreadnoughtus schrani, a massive, plant-eating dinosaur that researchers uncovered largely intact in Argentina. Though they found the fossil in 2005 and had it fully excavated by 2009, they have only now published the details of their find. And the details are incredible.

The dinosaur's tail was the length of a city bus. The creature weighed as much as seven times a single Tyrannosaurus Rex. Its body was the size of a house. All told, it weighed 65 tons and had a neck that was 37 feet long. Oh, and this one seemed to have been a growing adolescent.

Britain's The Register reports that one of the most remarkable parts of the discovery is how complete the fossil was. Scientists rarely find a large dinosaur fossil that is more than about a quarter complete — this one was about 50 percent complete. It seems the dinosaur was caught in a flash flood and became buried in mud.

The NATO alliance prepares to leap into cyberwarfare

NATO hasn't been able to do much to stop Russia's intervention in Ukraine, but NATO leaders want to make sure the alliance is ready to defend itself against growing Russian aggression online. At the NATO summit this week, they discussed extending their common defense pledge — an attack on one is an attack on all — into cyberspace.

Kenneth Geers, the ambassador for NATO's Cooperative Cyber Defense Center, says it's not just people or companies that are under threat of hacking, it's military forces themselves. That's because just about everything, including weapons, is connected to the Internet. He told PRI's The World that many countries are not well-equipped to combat cyberattacks, so they need to collaborate. That's a challenge, he says, because, up till now, few have been willing to share information on cyberwarfare, even with their allies.

A secretive hackers collective is already fighting a cyberwar — against ISIS militants

The hacktivist collective Anonymous declared cyberwar on the militant group known as the Islamic State, or ISIS, in June. ISIS is renowned for its use of technology and social media to spread fear and its message, in a way that previous terrorist organizations never have.

Motherboard reports on how that war is going, based on a source who claims to be within the Anonymous coalition of secretive hacking groups. The hackers are targeting sites and social accounts used by ISIS militants and working to shut them down. Both sides have reported some success in disrupting their opponents' work. Anonymous has a list of potential ISIS targets on the Internet, as well as a document cataloguing the group's broad Internet presence.

This is how an Amazonian tribe deals with illegal loggers

Indigenous tribes in northern Brazil have had it with illegal logging that is destroying their homeland. After receiving little help from the government in putting a stop to the logging, five tribes, including the Ka’apor Indians, are taking matters into their own hands, sending their warriors into the forests to capture and expel any loggers they find.

The tribal warriors, who are the legal custodians of the land, create camps in the areas where the loggers are active. They then capture the loggers, tie them up, strip them and use the loggers' own tools to destroy the loggers' harvest and their equipment. The Independent has the story, along with photos of the warriors in action.

How about a little grilled pigeon sushi for supper? 

If you sit down for a meal in Lima, Peru, you might happen on some pretty unusual twists on local cuisine. Thanks to waves of Chinese and Japanese immigration, Peru boasts homegrown Asian fusion cuisine.

PRI's The World has a story and photos of chifa and nikkei, food styles that are Asian-Peruvian mash-ups, which range from the simple — fried rice with corn — to the adventurous — guinea pig served with yucca cream. It looks delicious — and you're welcome to try some of those dishes before we dig in.

What we are seeing on social

Weather around the world

We've been telling you about Iceland's active Bardarbunga volcano. Now, let's turn to Hawaii, where a lava flow from its long-simmering Kilauea volcano has been advancing 800 feet a day for nearly a month. Yesterday, the mayor of Hawaii's Big Island declared a state of emergency in Puna county as the flow came within a mile of homes. The slow-moving lava could reach homes within a week. Weather.com has the details and photos from Kilauea, which has been continuously erupting since 1983.
