Hi Bob, I saw that in this mornings paper. I don't know which is more disturbing: Al Qaeda types looking to kill and maim indiscriminately in the name of their cause, or scientists making a living coming up with obscene discoveries such as this. How does this really benefit anyone? I am amazed these people can sleep at night knowing that they are making a career out of placing millions of people at risk. Brian

How fast do you really need to get there? Supersonic jet crashes in Outback test July 14, 2002 Posted: 5:32 PM EDT (2132 GMT) The supersonic jet explodes as it crashes into the ground WOOMERA, South Australia (Reuters) -- A test launch of what Japanese scientists hope will be the next generation of supersonic jet failed spectacularly in the Australian desert. The superjet, a 1:10 scale model of a plane that would be able to fly twice as fast as the Concorde, dived into the ground shortly after take-off on Sunday, a Reuters photographer on the scene said. "It spiralled in the sky and then crashed into the ground in flames," photographer Mark Baker said. The rocket-propelled 11.5-metre (almost 38-foot) model piggy-backed on a 10-metre (almost 33-foot) rocket, and was supposed to detach from the booster 18 km (11 miles) above the earth and glide back down at over twice the speed of sound. CNN NewsPass VIDEO A test launch of what Japanese scientists hope will be the next generation of supersonic jet failed spectacularly in the Australian desert (July 14) The developers of the aircraft, a project involving Mitsubishi Heavy Industries and Nissan Motor Corp, hope to cut the noise of supersonic flights to the rumble of a Boeing 747 so the superjet can fly anywhere. The test was originally supposed to have gone ahead on Thursday but had to be postponed because of bad wind conditions.

Researchers hide data in passport photos Technology would step up passport security August 7, 2002 Posted: 9:42 AM EDT (1342 GMT) LONDON, England (Reuters) -- Passport photographs in the future could be more than just a pretty picture if a new computer technique developed by Israeli scientists catches on. Researchers at Ben-Gurion University have devised a way to hide information such as a fingerprint or a signature in color images which could improve passport security or be used to create invisible product bar codes or designs. "The documents can be faxed, scanned and reprinted without the hidden data disappearing," New Scientist magazine said on Wednesday. Joseph Rosen and a team of scientists created an algorithm that converts a fingerprint or signature into a series of numbers which are used to shift the dots that make up a color picture. "Each dot can be displaced slightly without noticeably altering the final appearance of the image," the magazine said. Connect the dots Several images can be concealed in a single picture. Each image and the picture are scanned into a computer which does the work. The hidden images or fingerprints cannot be revealed until the picture is scanned again. The computer reconstructs the fingerprint by measuring the displacement of the dots in the picture. The magazine said that if the algorithm is distributed to passport checkpoints the picture can be unscrambled to reveal the fingerprint or signature and checked against the person holding the passport. The researchers are now working on a hand-held device which could make unscrambling the hidden information easier. cnn.com
