Have the right stuff? You could be NASA's next astronaut

You could be going into orbit and in one of the official snazzy NASA spacesuits, no less. That's if you are one of the elite group that the space agency chooses as its next cadre of future astronauts, of course.

NASA said today that beginning in early November, it will be accepting applications (PDF file) for its next class of astronaut candidates. These are the people who "will support long-duration missions to the International Space Station (ISS) and future deep space exploration activities," the agency said in the release announcing the upcoming application period.

Popular Mechanics Breakthrough Awards honor innovation

Popular Mechanics magazine on Monday unveiled its seventh-annual Breakthrough Awards winners, calling out 10 products and 11 innovators its editors feel are tackling longstanding problems in medicine, space exploration, technology, environmental engineering, and automotive design, in all-new ways.

Leading the list of this year's winners is "Avatar" director James Cameron, to whom the magazine gave its 2011 Breakthrough Leadership award.

The products honored by the editors include a hot new smartphone, an all-new kind of seat belt, a genre-shattering video game, highly efficient solar cells, smog-eating roof tiles, a new kind of LED lightbulb, and an automatic … Read more

Here's digital video of what we see inside our brains

I don't know what kinds of things you see inside your head, but I do worry about it.

As for the things I see inside my head, well, if only I could show you. Actually, there are scientists at UC Berkeley who believe that they can show you.

I haven't let them into the house yet. But I can show you video of their work. I am grateful to the inner brains at Gizmodo, who first revealed this footage to me.

You will, naturally, be wondering whether the scientists created this footage, well, naturally.

In a way. They … Read more

Physics shocker! Neutrinos clocked faster than light

European physicists have measured tiny particles called neutrinos moving just faster than the speed of light--only a smidgen faster, but enough to raise a serious possibility that Einstein's physics need a major overhaul.

The scientists sent a beam of neutrinos from CERN, on the Swiss-French border near Geneva, to the INFN (Istituto Nazionale di Fisica Nucleare) Gran Sasso Laboratory in central Italy, 730 kilometers (454 miles) away, in a research project called OPERA. The physicists had planned to study a rare event, the transformation of the muon variety of neutrinos into the tau variety. Instead, they found the extraordinary … Read more

Space tourism countdown begins as Virgin unveils factory

MOJAVE, Calif.--"We build spaceships."

That's the motto--perhaps the coolest ever?--of The Spaceship Company, the partnership between Richard Branson's Virgin Galactic and Scaled Composites, builder of the X-Prize-winning SpaceShip One and its younger sister ship, SpaceShip Two.

And on Monday, The Spaceship Company (TSC) formally opened what it calls FAITH, the final assembly facility for SpaceShip Two and the aircraft on which it piggybacks, WhiteKnight Two. At the celebration, Virgin Galactic showed off, for the first time at a public event, a replica of SpaceShipOne, as well as the actual WhiteKnightOne, SpaceShipTwo, and WhiteKnightTwo (… Read more

Raytheon passes major Navy destroyer radar milestone

Raytheon this morning said that it has passed a major milestone in its bid to win a multi-billion dollar U.S. Navy radar contract.

The Tewksbury, Massachusetts military contract is currently competing against Lockheed Martin and Northrop Grumman for the lucrative contract to provide next-generation Air and Missile Defense Radar (AMDR) technology for the Navy's Arleigh Burke-class destroyers. As part of its efforts to win the deal, Raytheon has just surpassed 1,000 hours of degradation-free testing on its Gallium Nitride transmit/receive modules. Completing the 1,000 hours of testing, during which the modules were said to have … Read more

VC legend Doerr: Tech is booming, not in a bubble

SAN FRANCISCO--In a "fireside chat" at TechCrunch Disrupt today, Silicon Valley venture capital guru John Doerr announced the launch of Erly, a new social network built around "experiences."

Doerr, the Kleiner Perkins Caufield & Byers partner who is considered among the most important VCs in Silicon Valley, said during an interview by TechCrunch founder Michael Arrington that Erly was built around the idea of "a different kind of interaction, an experience graph." Erly was founded by Eric Feng, the founder of Hulu (who was also a Kleiner, Perkins partner).

Erly's first product is … Read more

Gore tweaks climate call with '24 Hours of Reality'

Climate change activist, former vice president, and near-president Al Gore will present a 24-hour live Webcast--"24 Hours of Reality"--on September 14-15 that's meant to counteract what a statement about the event calls misinformation on global warming.

The Webcast consists of 24 back-to-back screenings of a new multimedia presentation by Gore, introduced live by presenters in 24 different parts of the world, and in 13 different languages. It heralds a new focus for Gore's nonprofit Alliance for Climate Protection, which is changing its name to The Climate Reality Project. Reads a statement on the Reality Project's Web site:

This campaign comes at a critical time. As the impacts of climate change are growing more prevalent, so is the resistance to finding the truth and implementing solutions. Just like the tobacco companies that spent decades in denial that smoking causes cancer, oil and coal companies are determined to sow denial and confusion about the science of climate change, ignore its impacts, and create apathy among our leaders. This event is the first step in a larger, multi-faceted campaign to tell the truth about the climate crisis and reject the misinformation we hear every day."

British atomic clock is world's most accurate

British and U.S. scientists have confirmed that an atomic clock at the National Physical Laboratory (NPL) near London is the most accurate long-term timekeeper in the world, the NPL said.

The NPL-CsF2 is a cesium fountain clock that's used as a standard for International Atomic Time and Universal Coordinated Time.

The machine is apparently accurate to within two 10 million billionths of a second. Not bad, I guess.

The NPL's Krzysztof Szymaniec joined scientists from Pennsylvania State University in evaluating the clock. The team published its results in the journal Metrologia.

The analysis concludes that the clock will lose only a billionth of a second every two months, and represents an unprecedented accuracy. Cesium clocks are usually expected to lose or gain a second over tens of millions of years.

"Together with other improvements of the cesium fountain, these models and numerical calculations have improved the accuracy of the U.K.'s cesium fountain clock, NPL-CsF2, by reducing the uncertainty to 2.3 × 10-16--the lowest value for any primary national standard so far," Szymaniec was quoted as saying by the NPL.

In the U.S., the National Institute of Standards and Technology operates the NIST-F1 cesium fountain clock, which as of summer 2010 had an uncertainty of 3 x 10-16, meaning it would take more than 100 million years to lose or gain a second.

That will be billions of years before the sun dies, taking the Earth with it, so I expect an update on this from a future blogger. … Read more
