Cutting Edge

In another sign of ever-increasing commercial spaceflight activity, Sierra Nevada's Dream Chaser space plane has arrived at NASA for testing.

Wrapped in plastic, the craft arrived at NASA's Dryden Flight Research Center at Edwards Air Force Base, Calif., where it will eventually undergo its first autonomous free flight Approach and Landing Test (ALT).

Part of NASA's Commercial Crew Program along with SpaceX and Boeing, the Dream Chaser is designed to launch vertically on top of an Atlas 5 rocket, dock with the International Space Station, and then return to Earth like a glider, landing on a runway. … Read more

Thanks to the magic of dissection, we have a pretty good idea of the changes that occur when a caterpillar spins its chrysalis and enters its metamorphosis -- the developmental stage that sees it move from the juvenile larval stage to the gorgeous adult life of a butterfly.

However, as you might have already guessed, dissection destroys the specimen, meaning that researchers are unable to follow the full development of a creature. We do know that the caterpillar will use enzymes to break down some of its proteins to reform; Scientific American called this a cocoon full of "caterpillar soup." However, scientists have performed research revealing that while some breakdown occurs, the idea of caterpillar soup is mostly wrong (but still gross).

Using micro-computed tomography, or micro-CT scanning, which uses X-ray imaging to re-create 3D cross-sections of the scanned object, Tristan Rowe and Russell Garwood from the U.K's University of Manchester and Thomas Simonsen from London's Natural History Museum have discovered exactly what happens to a painted lady butterfly inside the chrysalis. … Read more

Google is opening a new research lab to see if a quantum computer can solve problems too taxing for traditional computers.

Hosted by NASA's Ames Research Center, the new Quantum Artificial Intelligence Lab will be home to a quantum computer made by D-Wave Systems. Operated by the Universities Space Research Association, the supercomputer will be available to researchers around the world to work on their own projects.

The goal, as stated in a Google blog posted today, is "to study how quantum computing might advance machine learning."

Traditional computers are limited, as they think in terms of … Read more

The Kepler space observatory has been a source of great wonder since it first launched in 2009. It has turned its eyes out into the great vastness of space and seen new planetary systems and potentially life-supporting planets. The telescope's original 3.5-year mission was extended into 2016, but that may now come to a halt as serious technical issues take a toll.

Kepler is able to look out in certain directions thanks to four reaction wheels that are used to point the spacecraft. As of Wednesday, two out of four reaction wheels have failed.… Read more

SAN FRANCISCO--Parties can say a lot about the companies that hold them.

So it was with Google I/O Wednesday night at the Moscone Center West here. Classic rocker Billy Idol was the headliner, jumping around the stage shirtless, and a profanity-prone DJ caught some attention afterward, but the audience paid just about as much attention to the multitude of robot exhibits.

There were robots you could train to pick up jars, robot bartenders, life-size Rock-em Sock-em robots in a boxing ring, and remote-control robots people could ride around on.

Best of all was a giant hydraulic arm that would … Read more

Allure Energy sued Nest Labs yesterday, claiming that the company's much-celebrated Nest Learning Thermostat infringed on its patent.

Filing the suit in the United States District Court for the Eastern District of Texas, the Austin, Texas-based Allure alleged that its patent for the invention of an "Auto-adaptable energy management apparatus" trumped Nest's right to develop, market, and sell a smart thermostat.

Allure said it first began designing its product, which is known as EverSense, in 2009, and filed it patent application in 2010. The company said in a release that it also got a patent for &… Read more

Andreessen Horowitz, one of the most prominent Silicon Valley investors, is leading an investment round in a company that's developing software for the commercial use of drones.

Called Airware, the Newport Beach, Calif., company provides several different platforms and tools for companies that want to invest in unmanned aerial systems (UAS), otherwise known as drones. Andreessen Horowitz led the funding round in the drone company, which raised $10.7 million. Google Ventures also participated in the round, according to All Things Digital, which was first to report on the news.

The key difference between Airware and the drones we … Read more

We've seen some pretty out-there limited-edition cars from luxury manufacturer Lamborghini, but its newest may have just taken the biscuit and sped off with it.

The Egoista, unveiled at the closing gala of the 50th anniversary Grande Giro tour, was designed by Volkswagen's head of design, Walter De Silva, and it's meant to be the ultimate in self-indulgence.

"This is a car made for one person only, to allow them to have fun and express their personality to the maximum," De Silva said. "It is designed purely for hyper-sophisticated people who want only the most extreme and special things in the world. It represents hedonism taken to the extreme, it is a car without compromises, in a word: egoista (selfish)." … Read more

Mercedes-Benz announced it would demonstrate Google local search, Street View, and traffic integrated into the dashboard of one of its vehicles during Google I/O. These features will be introduced soon as part of Mercedes-Benz's DriveStyle app.

Local search will let drivers enter any term to begin a search, resulting in a list of nearby place names. Each entry can be selected as a destination for navigation. The Street View feature will let the driver see a 360-degree view of any destination, as long as Google has covered it.

Traffic data is similar to what can be found on … Read more
