Technology

We've talked in this space in the past few months about detecting the existence of Earth-like planets in other solar systems, and on the educated guesswork which goes into putting a number on the probability of intelligent life existing out there as well. You may remember that the discovery of terrestrial planets is well on its way as technology improves; and that the Drake equation—with all its assumptions—has proved to be remarkably accurate.

If a sodden rice paddy feels soft and forgiving underfoot, it is not a merciful place to set down an airplane at 200 mph. And that’s only one of Mike Selby’s reasons to look nervous as he watches his A-10 Warthog—a 10-foot-wide, 65-pound, hand-built model—begin its maiden takeoff roll down a rough asphalt runway near Bangkok, Thailand. Selby, who spent over $12,000 and the better part of a year fabricating and building this radio-controlled jet, stands runwayside with his thumbs hooked into the belt loops of his jeans, trying to look relaxed as he draws on a Cuban cigar.

Kids' stuff? Hardly. RC jets are the topic of this week's podcast, but if you think you know model planes, think again. Host Chuck Cage sits down with writer Tom Clynes and staff photographer John B. Carnett to discuss the Air Force pilots, sophisticated machinery and big money behind this high-stakes hobby.

Twitter has had its share of bad press lately, namely that it was all but unusable for weeks last year due to an overwhelming server load. This week, however, things are looking up for the messaging service. Not only have their tubes been clog-free, but something happened to one of its members that illuminated just what it is Twitter may be good for (something more than a few people have been trying to figure out): letting people know when youre headed to jail.

Last April, we dissected the worlds most advanced fighter jet, the F-35B Lightning II, in the pages of our annual How It Works issue. Now military contractor Lockheed Martin is firing up the jets 40,000-pound-thrust engine (the most powerful ever built for a fighter jet) in preparation for flight tests. The jet can soar at supersonic speeds (1,000 mph) and deflect radar signals, but by the end of the month, pilots are expected to show off its most highly anticipated feature: the ability to stop mid-flight and touch down virtually anywhere.

It packs 4 million times more material than our sun, but relative to the black holes sitting at the center of some neighboring galaxies, it actually doesn't do all that much. The fact that this black hole, known as Sagittarius A*, kicks out billions of times less energy than others of its kind has made it something of a mystery. But now a team of scientists at Kyoto University suggests that Sagittarius A* may be resting after a far more active period a few centuries ago.

Setting a spacecraft down on Mars isn't exactly easy—just ask Beagle 2. NASA's Phoenix Mars Lander, en route and due for a May 25 rendezvous with the surface, recently received a course adjustment from mission planners as they try to ensure that the craft doesn't drop down in a danger zone.

I don't know about you, but when airline pilots organize themselves enough to protest their employer's overall poor performance—not, I'd like to point out, merely their crappy pay—that gets my attention. That's precisely what hundreds of American Airlines pilots intend to do tomorrow in nine cities around the country. They'll be demonstrating at major airports to "encourage passengers to help AA employees get management's attention" to fix problems relating to performance and customer service. Specifically, American has the worst on-time performance among network carriers. The pilots are also, naturally, not particularly amused about the nose-gear-wiring fiasco that grounded hundreds of aircraft and caused countless traveler delays last week.

Less than fifteen years ago, the concept of an extrasolar planet orbiting a star much like our own was only a theory. Since that time, we've discovered nearly 300 extrasolar planets in all, but have consistently failed to find systems which orbit around stars resembling the sun. Today, the BBC is reporting on a find by astronomers from St. Andrews University of two gas giants on par with Saturn and Jupiter in orbit around a star half the size of our sun. While the finding is not a direct link to a system similar to ours, it does present an increased likelihood that our system is not unique.

Dont count the Rocket Racing League out just yet. After a lengthy delay and intimations of its demise, the league has finally announced exhibition flights. Pending FAA approval, a ten-minute flight will take place the first weekend of August at this summers EAA Airventure festival in Oshkosh, Wisconsin. Granger Whitelaw made the announcement this morning at a press conference in New York, admitting that the news was coming some fifteen months later than he had hoped. I will take full responsibility for the delay, he said.

Nintendo Wii devotees are likely already familiar with Johnny Chung Lee as the guy who appeared one day last year on YouTube with a mind-bender of a demo on how to use the Wii remote and sensor bar to do head tracking. By placing the Wii remote at the base of a TV and attaching the sensor bar to a pair of glasses (and in conjunction with a bit of custom software), Lee made the three-dimensional images on screen respond to his position in space, appearing to float off in front of the screen. As it turns out, Lee is more than just a guy with a knack for understanding the Wii remote; he's currently a graduate Ph.D. candidate in the Human-Computer Interaction Institute at Carnegie Mellon University. And he's so impressed the gaming world with his developments that EA is bringing a Wii game to market this spring with a head tracking Easter egg.

Its blockbuster season, and that means mad scientists, angry robots and a certain flexibility with the laws of physics. Heres our guide to movies made especially with PopSci fans in mind. In it, a roundup of the season's best (and worst) geek candy, along with our expected gibberish quotient, so youll know which lines are pure comedy—even if no one else is laughing.

Filming conventional high-speed action fare is hard enough, but to bring the classic cartoon Speed Racer to life, the Wachowski brothers had to contend with 300mph racecars sporting fanciful features like robotic reconnaissance pigeons and wheels that can rotate 180 degrees. With 2,300 visual-effects (VFX) shots—twice as many as last year’s eye-popping 300—it heralds the future of summer-blockbuster fare: The entire movie, aside from the human actors, exists only in a computer.

The Defense Advanced Research Projects Agency, or DARPA, celebrated its golden anniversary last night in typically low-key style with a banquet here at the Washington Hilton.

The 1,600 tuxedoed attendees included nine former DARPA directors, program managers past and present, and scientists and engineers from DARPA's contractors in the private sector and academia.

We're happy to bring you the first installment of our newest regular blog column, "Playing Around" with Steve Morgenstern. Since his days as founding editor of Atari Age, one of the first videogame magazines (covering the hallowed Atari 2600), Steve has served as reviewer, industry pundit and even a game developer. In his new column he'll focus on the latest developments in the art and science of electronic amusement, ranging from game design innovations to intriguing new technologies to lifestyle and culture in the interactive age. Without further ado, here's Steve. [Eds.]

It's illegal to wager on online games, right? Don't bet on it! Our nation's lawmakers, ever vigilant against sins they're not personally committing, passed the Safe Port Act in 2006. The bill combines maritime-security enhancements, the creation of the Domestic Nuclear Detection Office and, in a spectacular nonsequitur, the Unlawful Internet Gambling Enforcement Act, effectively banning games of chance by making it illegal to transfer money to an Internet casino. Games of skill, though, weren't affected.
