IBM stores bits on arrays of atoms, shrinks magnetic storage to the scientific limit
IBM's Almaden Research Center is filled with some of the best and brightest minds in the world, and its researchers just released new findings that detail how just how far IBM has come in the realm of magnetic storage. Andreas Heinrich is leading the team at Big Blue that figured out how to create atomic storage based on the fact that atoms of ferromagnetic material align their spins in one direction -- so the ability to control the spin direction is what's needed to make such minature memory possible. Heinrich and his crew were able to accomplish the trick by supercooling 12 atoms to four degrees kelvin (-452 fahrenheit), and arranging them using an electron microscope in such a away that nonvolatile storage became possible. As this is only a proof of concept, we won't be seeing atomic memory at, say, CES any time soon, but you can dig into the deep science behind the breakthrough at the source link below.
'3D Towers' double disk storage capacity, don't require glasses
Here's some exciting news for all you data storage enthusiasts and academics out there: researchers in France have found a way to double the storage capacity of magnetic disk drives by constructing "3D towers" of information. The team from SPINTEC created these pillars out of bit-patterned media -- separated magnetic nanodots, each of which carries one bit of data. By layering the dots in specific formations, the team created a "multilevel magnetic recording device" with an areal density of two bits per dot -- twice what it started with. According to researcher Jerome Moritz, these findings could provide IT companies with a new way to circumvent physical limitations to their data storage capacities, allowing them to build up and over the vaunted one Tbit per square inch barrier. The team's full findings were recently published in the American Institute of Physics' Journal of Applied Physics.

JingJing and PuiPui bots followup on the BHR tai chi bots, give a good interview
The fine folks at the Beijing Institute of Technology just unveiled a pair of new bots, dubbed JingJing and PuiPui. Back in 2003 BIT was showing off its BHR-1 and BHR-2 bots, life-sized humanoids that can do tai chi, and these new bots keep their predecessor's martial arts capabilities but add in some conversational skills. During what sounds to have been a charming unveiling, the bots answered questions from the audience, self-identifying themselves as humanoid robots to an enraptured crowd. Their creator claims we're entering a personal computer revolution-style era with robots, and while we've heard that claim before, boy do we want to believe it! Check out a video of the original BHR series performing their moves to an epic soundtrack after the break. [Via Plastic Pals]
Ask PSP Fanboy: Volume 8
Note: This edition was delayed due to New York Comic Con.Every Saturday, PSP Fanboy will answer your burning questions. If you have a question for the team, send an e-mail to andrew @ pspfanboy.com with the subject "Ask PSP Fanboy."Q: The Mega Drive was 16-bit, the PS1 was 32-bit, the N64 as 64-bit, and the PS2 was 128-bit. We don't use the word "bit" with the new genrations of consoles. Why is that? A: Bits simply don't matter anymore. Why? Because most information you'll need will fit into 32 bit packets. Also, what are we measuring bits from? We have multiple CPUs, GPUs (and even PPUs) in modern gaming equipment, all of varying bit qualities. The PSP has a 32-bit CPU with a 128-bit bus and a GPU with a 256-bit bus. However you want to spin that, that either means the PSP is a 32-bit or a 256-bit system. Hopefully, this proves how useless these "bit" numbers are in determining performance.
