BOFFINS AT Rice University have managed to decode the three-dimensional structure of a magnetic vortex which is smaller than a red blood cell.

The breakthrough means that it will be eventually possible to create magnetic hard-drives which can manage terabits of data per square inch.

Lead researcher Carl Rau used a scanning ion microscope to create and measure ultra-thin circular disks of soft magnetic cobalt.

They managed to isolate a single vortex was found on disks measuring six microns in diameter. Compared to regular electronic devices, magnetic devices using the tornado nanotech would be faster, smaller and they would not lose information when power was turned off.

Authorities in several countries raided Megaupload recently, shut down all of its services, seized hundreds of servers and arrested several of its executives on criminal charges.

Do you think the move was justified?

Yes, companies should suffer an immediate death penalty upon being accused of copyright infringement.

Yes, the coppers said the company was breaking the law so it must be guilty.

No, the company and the people accused are innocent until proven guilty.

No, the company had millions of customers who have been harmed by having access to their data files cut off.

I don't care, I never used Megaupload anyway.
