Submission + - In major shift, Firefox to use Yahoo search by default in US (cnet.com)

mpicpp writes: Google's 10-year run as Firefox's default search engine is over. Yahoo wants more search traffic, and a deal with Mozilla will bring it.

In a major departure for both Mozilla and Yahoo, Firefox's default search engine is switching from Google to Yahoo in the United States.

"I'm thrilled to announce that we've entered into a five-year partnership with Mozilla to make Yahoo the default search experience on Firefox across mobile and desktop," Yahoo Chief Executive Marissa Mayer said in a blog post Wednesday. "This is the most significant partnership for Yahoo in five years."

The change will come to Firefox users in the US in December, and later Yahoo will bring that new "clean, modern and immersive search experience" to all Yahoo search users. In another part of the deal, Yahoo will support the Do Not Track technology for Firefox users, meaning that it will respect users' preferences not to be tracked for advertising purposes.

With millions of users who perform about 100 billion searches a year, Firefox is a major source of the search traffic that's Google's bread and butter. Some of those searches produce search ads, and Mozilla has been funded primarily from a portion of that revenue that Google shares. In 2012, the most recent year for which figures are available, that search revenue brought in the lion's share of Mozilla's $311 million in revenue.

Permanent Undersea Homes Soon; Temporary Ones Now 122

MMBK writes "Dennis Chamberland is one of the world's preeminent aquanauts. He's worked with NASA to develop living habitats and underwater plant growth labs, among other cool things. His next goal is establishing the world's first permanent underwater colony. This video gets to the heart of his project, literally and figuratively, as most is shot in his underwater habitat, Atlantica, off the coast of Key Largo, FL. The coolest part might be the moon pool, the room you swim into underwater."

Submission + - European physicists take photo of neutrino

An anonymous reader writes: European physicists said Tuesday they had sent an elusive particle known as a neutrino on a 730-kilometer (456-mile) trip under the Earth's crust and taken a snapshot of the instant it slammed into lab detectors. In the October 2 event, a neutrino hit one of the 60,000 bricks that had been installed in San Grasso, leaving a tell-tale track of a muon on the film. The experiment is important, say the investigators, as it could help explain one of the biggest mysteries about the Universe — its missing mass. When scientists tot up the mass of all the visible matter in the Universe, they arrive at a total of just 10 percent of what they know to exist. For years, neutrinos were not thought to have any mass, although that theory has been challenged by experiments at Japan's SuperKamioKande lab, which suggested that they may have a mass, albeit a very tiny one.

Submission + - 2 killed in SpaceShipTwo motor test explosion (cnn.com)

RZG writes: Two people were killed and 4 were injured during a "cold fire test" of the motor for SpaceShipTwo. This obviously is a setback for Virgin Galactic and the non-government space community in general. "Aerial video of the blast aftermath showed a charred and twisted flatbed trailer attached to a truck cab with a large silver tank next to it. Large pieces of debris appeared to be strewn for hundreds of yards from the center."

the_Bionic_lemming writes: An explosion at an airport home to Scaled Composites — the builder of the first private manned rocket to reach space — killed two people and left four seriously hurt Thursday, a Kern County Fire Department official says. It happened at the Mojave Air and Space Port during a test of a new rocket motor for SpaceShipTwo — a spaceship being built for Virgin Galactic, Richard Branson's space tourism company, a source said. The motor uses nitrous oxide, the source said.
