Experts Re-Create Nazi 'Stealth' Fighter to Test Tech

The last remaining Horten 2-29, a Nazi fighter plane from World War II, is stored in a U.S. government warehouse akin to the one at the end of 'Indiana Jones and the Raiders of the Lost Ark.' With a mostly pressed-wood body and a sleek all-wing design, it looks like something created in Hollywood, too. But this aircraft isn't just a pretty piece of painted plywood. It very well could have changed the course of the war.

A group of experts from Northrop Grunman, a global security company, recently re-built the Horten 2-29 for a television special airing Sunday on the National Geographic Channel. The team's goal was to determine if the rumors were true; was the Horten 2-29 the world's first stealth fighter? They tested the original aircraft with WWII-era radar technology before building a model held together with primarily wood and glue. Then, they hoisted it on top of a five-story column and subjected the model to the same radar technology.

Cloaking Device May Make Cell Phone Static Vanish

There has been plenty of research into cloaking devices, but while scientists are still working their way towards the visible light spectrum they seem to be having the best luck with microwaves. Most recently, a new metamaterial made from over 10,000 individual pieces of fiberglass has been used to cloak a bump on a flat mirrored surface -- the material prevents microwaves from being scattered, giving the RADAR (we're guessing it's a RADAR) the impression that the surface is flat. This has many possible applications, such as cloaking sources of interference to cellular communications. Unfortunately, the implication we most desire -- rendering us invisible during high society jewel heists -- has yet to become reality.

Better Pitching Through Technology

Better Ks Through Technology

Whether you're the office softball team's hurler looking to improve, or the entire Phillies bullpen searching for a prayer, RevFire may be the answer. The new pitcher's tool features two bionic balls that look and feel like the regulation stuff, but have sensors embedded deep within. Those sensors allow the system's hand-held monitor to track speed, rotation speed and the number of pitches thrown in a given session -- all vital info for those working on either improving or rehabilitating their arm.

At $398 for either the softball or baseball version, the RevFire isn't exactly an affordable option for the average Pee Wee leaguer. However, for those who can afford to spend upwards of $300 on a standalone radar gun, the extra info provided by the RevFire is well worth the extra expense.
