It is called the TeraDisk and it is really small, like a ordinary CD/DVD. But it’s really huge in terms of space. 1 TB (1000 GB). How can this be done? The process is easy (or not). All existing optical media record data on semitransparent layers. A regular CD has 1 layer and a Blu-Ray disk has up to 8. The reason nobody can add more layers on a regular CD/DVD/Blu-Ray disk is because when the light passes through these layers it becomes distorted and by the time it reaches the final layers it becomes almost impossible to read/write on the disk.

TeraDisk achieved the 1TB limit by using 200 layers, each storing 5GB of data. So basically the data support stay the same (TeraDisk will be made out of the same plexiglas like material used in other disks) but the write/read laser technology is completely new. They say it’s going to be cheap and it will be available for the public in 2010.

A British company has developed a camera that can detect weapons, drugs or explosives hidden under people's clothes from up to 25 meters away in what could be a breakthrough for the security industry.

The T5000 camera, created by a company called ThruVision, uses what it calls "passive imaging technology" to identify objects by the natural electromagnetic rays -- known as Terahertz or T-rays -- that they emit.

The high-powered camera can detect hidden objects from up to 80 feet away and is effective even when people are moving. It does not reveal physical body details and the screening is harmless, the company says.

The technology, which has military and civilian applications and could be used in crowded airports, shopping malls or sporting events, will be unveiled at a scientific development exhibition sponsored by Britain's Home Office on March 12-13.

"Acts of terrorism have shaken the world in recent years and security precautions have been tightened globally," said Clive Beattie, the chief executive of ThruVision.

"The ability to see both metallic and non-metallic items on people out to 25 meters is certainly a key capability that will enhance any comprehensive security system."

While the technology may enhance detection, it may also increase concerns that Britain is becoming a surveillance society, with hundreds of thousands of closed-circuit television cameras already monitoring people countrywide every day.

ThruVision came up with the technology for the T5000 in collaboration with the European Space Agency and from studying research by astronomers into dying stars.

The technology works on the basis that all people and objects emit low levels of electromagnetic radiation. Terahertz rays lie somewhere between infrared and microwaves on the electromagnetic spectrum and travel through clouds and walls.Depending on the material, the signature of the wave is different, so that explosives can be distinguished from a block of clay and cocaine is different from a bag of flour.

What's that? You didn't take the risk and upgrade your PC to some crappy Intel-based machine Microsoft may or may not have known wouldn't run Vista as promised? Well, at least now you can get in on the latest version of Windows a little cheaper than yesterday: Ultimate full looks to be officially headed down to $320 from $400, and the upgrade is down to $220 from $260; Home Premium is now at $130 from $160. Will the dip be enough to entice plenty of new OS upgraders? Perhaps, but we think most of those that haven't already upgraded will probably just wait until their next PC so they can get Vista "free". But if you're looking to buy it boxed though, give it a bit for the new prices to propagate through the retail network -- not even Microsoft's site reflects the new Vista price points.
