Super-Light Plastic As Strong as Steel 226

Roland Piquepaille writes "A new composite plastic built layer by layer has been created by engineers at the University of Michigan. This plastic is as strong as steel. It has been built the same way as mother-of-pearl, and shows similar strength. Interestingly, this 300-layer plastic has been built with 'strong' nanosheets of clay and a 'fragile' polymer called polyvinyl alcohol (PVA), commonly used in paints and glue, which acts as 'Velcro' to envelop the nanoparticles. This new plastic could soon be used to design light but strong armors for soldiers or police officers. The researchers also think this material could be used in biomedical sensors and unmanned aircraft."

Feed Science Daily: Source Of Fever Identified (sciencedaily.com)

With the finding that fever is produced by the action of a hormone on a specific site in the brain, scientists have answered a key question as to how this adaptive function helps to protect the body during bacterial infection and other types of illness.

id and Valve May Be Violating GPL 399

frooge writes "With the recent release of iD's catalog on Steam, it appears DOSBox is being used to run the old DOS games for greater compatibility. According to a post on the Halflife2.net forums, however, this distribution does not contain a copy of the GPL license that DOSBox is distributed under, which violates the license. According to the DOSBox developers, they were not notified that it was being used for this release."

Web 2.0 Bubble May Be Worst Burst Yet 417

athloi writes with a link to an editorial by John Dvorak over at the PC Magazine site. Rather than his usual tilting at windmills, Dvorak turns his attention to possibility of another big internet economy 'pop': "Every single person working in the media today who experienced the dot-com bubble in 1999 to 2000 believes that we are going through the exact same process and can expect the exact same results — a bust. It's déjà vu all over again. Each succeeding bubble has been worse than its predecessor. Thus nobody is actually able to spot the cycle, since it just looks like a continuum. I can assure you that after this next collapse, nobody will think of the dot-com bubble as anything other than a prelude." It certainly seems like another burst is imminent; will this one be worse than the original, or have less of an impact?

Submission + - Perfect silicon sphere to redefine the kilogram (theage.com.au)

MrCreosote writes: The Age reports optical specialists at CSIRO are helping create a new standard for the kilogram, based on a precise number of atoms in a perfect sphere of silicon. This will replace the International Prototype, a lump of metal alloy in a vault in Paris.

In today's press conference a NASA official dismissed the importance of the debri that hit the left wing on launch. After all it happened in two of the previous three shuttle missions, and nothing happened.

Exactly. The orbiter is designed to have a few tiles break off, crack, etc. This was one of the advantages of using these heat-absorbant tiles, and engineers reviewed this when they designed the shuttle.
