X-ray Scotch Tape
???? Yes if you peel scotch tape in a vacuum it emits x-rays that are powerful enough to actually use with x-ray film. A couple of scientists in California discovered this and even took an x-ray of their finger to prove it. They say that it’s safe to use tape in your office because the radiation doesn’t happen in the presence of air, but if you need to fix a vacuum chamber with scotch tape you need to be careful.
We’re Still Alive
They’ve turned on the LHC (Large Hadron Collider) and the universe as we know it didn’t collapse. For awhile it was thought that this massive machine would cause a cataclysmic black hole that would suck in the entire universe, they were wrong. Hooray!!

Encyclopedia of Life – Now Online
The encyclopedia of Life that I wrote about some time ago, has just brought it’s first 30,000 pages online. The goal of the project which is slated to last 10 years is to catalog the entire earths known living species, all 1.8 million. Though 30,000 pages are now up only a handful a fully complete and approved by scientists, the rest serving as placeholders that haven’t been authenticated by scientists yet. You can see the list of exemplar pages as they call them, that are fully approved, here. Later on this year the site will be opened to the public for contributing different materials to be incorporated into the project.
Disk Encryption Defeated
It appears that the disk encryption schemes used by different operating systems can be easily circumvented. Princeton Researchers have disproved a common misconception of one of the key components of a computer, that the system’s RAM loses all information stored on it as soon as power is cut from the chip. The researchers claim that the contents of the memory remain for seconds after the power is cut, and if cooled to low temperatures that that time can be extended to hours.
Princeton computer science professor Edward W. Felten, states that by using an inverted can of compressed air, a common item in most offices, you can effectively freeze the data on the chip for 10 minutes. In contrast using liquid nitrogen, not so common item in the office unless it’s a cryogenics office, the time can be increased to hours. Then the ram can be used cold boot the machine and the encryption key is still on the memory and can be used to access the encrypted disc contents.

Sony Helps Fight Diseases
Many may be aware of the Folding@home project run by Stanford University, but thanks to Sony now they have a Guinness record. This record certifies the Folding@home project as the most powerful distributed computing system, reaching over 1 petaflop (thousand trillion floating point operations per second). In comparison the SETI@home project has only reached 256 teraflops (265 million floating point operations).
What does Sony have to do with the record. Well more than 600,000 PS3 owners have been donating their spare cpu cycles to the project and this along with others donating their PCs spare cycles have netted the project the World Record.
