The DIY Tank 334

Will Foster, a Kettering University student, has built his own half sized Panzer tank. It took Will 2 years and around $10,000 to build his mini-tank and he says the process has been "a lot of trial and error...I'd buy a $200 part that didn't work, then go to a $300 part that didn't work before finding a $50 part that did." The tank is about as big as a small car, and can reach speeds of around 20 mph with its three-cylinder diesel engine. It runs on treads, has a cannon powered by compressed air from a scuba tank and parks wherever the hell it wants.

NASA Plans to Smash Spacecraft into the Moon 176

djasbestos writes "NASA is planning to smash a spacecraft into the Moon in order to look for hydrogen deposits in the poles. More notably, it will impact with significantly greater force (100x, per the article) than previous Moon collisions, such as by the Lunar Prospector and Smart-1 probes. Admiral Ackbar was unreachable for comment as to the exact location and size of the Moon's thermal exhaust port."

Laser Light Re-creates 'Black Holes' in the Lab 245

yodasz writes "The New Scientist reports that a team of researchers from the UK were able to recreate a black hole's event horizon in the lab by firing a laser pulse down an optical fibre. The team's observations confirm predictions made by cosmologists and now they are trying to prove Hawking's hypothesis of escaping particles, dubbed Hawking radiation. 'The first pulse distorts the optical properties of the fibre simply by traveling through it. This distortion forces the speedy probe wave to slow down dramatically when it catches up with the slower pulse and tries to move through it. In fact, the probe wave becomes trapped and can never overtake the pulse's leading edge, which effectively becomes a black hole event horizon, beyond which light cannot escape.'"

Haiku OS Resurrects BeOS as Open Source 269

Technical Writing Geek writes "The Haiku project, which began shortly after the death of BeOS in 2001, aims to bring together the technical advantages of BeOS and the freedom of open source. 'The project has drawn dozens of contributors who have written over seven million lines of code. Although Haiku is nearly feature-complete, there are still numerous bugs that must be fixed before it is ready for day-to-day use. The design principles behind Haiku are very closely aligned with those of BeOS. The central goal of the Haiku project is to create an operating system that is ideally suited for use on the desktop--this differs significantly from Linux and other open-source operating systems which are intended for use in a diverse range of settings including server and embedded environments.'"

Could We Find a Door To A Parallel Universe? 327

p1234 writes "Though no direct evidence for wormholes has been observed, this could be because they are disguised as black holes. Now Alexander Shatskiy of the Lebedev Physical Institute in Moscow, Russia, is suggesting a possible way to tell the two kinds of object apart. His idea assumes the existence of a bizarre substance called "phantom matter", which has been proposed to explain how wormholes might stay open. Phantom matter has negative energy and negative mass, so it creates a repulsive effect that prevents the wormhole closing. 'US expert Dr Lawrence Krauss, from Case Western Reserve University in Cleveland, Ohio, points out that the idea rests on untested assumptions. He told New Scientist magazine: "It is an interesting attempt to actually think of what a real signature for a wormhole would be, but it is more hypothetical than observational. Without any idea of what phantom matter is and its possible interactions with light, it is not clear one can provide a general argument."'"

Third Undersea Cable Cut 655

Many readers are reporting that another undersea fiber optic cable has been cut, apparently caused by another wayward anchor. It looks like Iran has completely lost Internet connectivity."

Going to Yosemite? Get Your Passport Ready! 969

rev_media writes to tell us that CNN has a few updates to the Real ID act currently facing legislators. The Real ID acts mandates all states to begin issuing federal IDs to all citizens by 2008. Costs could be as much at $14 billion, but only 40 million are currently allocated. Several states have passed legislation expressly forbidding participation in the program, while others seem to be all for it. The IDs will be required for access to all federal areas including flights, state parks and federal buildings. People in states refusing to comply will need to show passports even for domestic flights.

Wikia Acquires Grub, Releases it Under Open Source 119

An anonymous reader writes "During a keynote address at the O'Reilly Open Source Conference (OSCON), Jimmy Wales announced that Wikia has acquired Grub, the original visionary distributed search project, from LookSmart and released it under an open source license for the first time in four years. Grub operates under a model of users donating their personal computing resources towards a common goal, and is available for download and testing."
