Protein-Packed Hard Drives Promise High Capacity
Digimax writes "The New Scientist has an interesting article on a technology being developed by NanoMagnetics which involves using a protein responsible for storing iron in the body to store data on a hard drive. Is this the start of the BioTech revolution?"
Yea, this is all fine and dandy, but doesn't help with speed.
The real revolution waiting to happen is solid state hard drives that are affordable. Until we get rid of the moving parts, hard drives are going to be very very slow, relatively speaking. For the desktop, this is more important that storage space, since we already have 240gb drives that few can fill.
Tequila: It's not just for breakfast anymore!
Actually the first "BioTech" would probably be something along the lines of the smallpox vaccines that were manufactured by injecting horses and then taking the serum from the blood for the antibodies.
In the harddrive case, it's a mechanical good. In the smallpox case, it's a medicine. Both are certainly ways to use biological means for manufacturing.
If someone can think of an earlier biotech, please feel free to let us know!
New Scientisct article writen by somebody ignorant in material science: skips the important stuff and dwells on marginal. The company site more informative.
Magnetic particles in storage media must be evenly spaced and right size. This protein is used as a mold and spacer for making and placing the magnetic particles. The protein is spherical, has cavity which can be filled with magnetic stuff and forms crystal-ordered-like monolayer on support surface. Burning the protein leaves the magnetic particles in caramelized yuck. All this done in with external magnetic field. And since we are baking it well above Curie temperature of the magnetic material, cooling will produce the particles nicely magneticaly aligned.

I doubt that we will ever figure out - and I suspect that even if we did figure out we couldn't do much about it
I'm going to point out something that no one else seems to have noticed yet. This is an article in New Scientist, that should be enough said who ever actually read it. The have a real penchant for investigating off the wall oddball ideas then writing up the issue with just enough slant that one who reads it takes the same mentality as those who think cars which run on water have been made but are being held back by the big car manufacturers and oil companies. Virtually every issue of New Scientist has at least ONE grand convoluted conspiracy theory. I'm not saying there is no basis at all for this, just that New Scientist isn't exactly a reputable news source much less something approaching a peer-reviewed scientific journal. They are much more like Scientific American but don't even approach that level of credibility.
That said, go ahead and debate it all you want. I just think (as a molecular biologist...more DNA focused than applied protein mechanics like this, but still fairly well versed) that by the time all the "bugs" for this are worked out we'll have leapfrogged the whole idea of magnetic media Winchester syle drives. This is the equivalent to making a perfect artificial diamond point for a record player, by the time we had the tech to do it the world had already moved onto CDs or other media for the overwhelming majority of uses of said records...People still make record players, but they are a niche market to say the absolute least.
On a similar vein, the first noted instance of BioWarfare being employed occured during the Middle Ages. Plague (Yersinia pestis) infected bodies were catapulted over the high walls of fortified strongholds. The hope was that the contagion would spread to the inhabitants.

p.s. I see a lot of biology misinformation on slashdot. I'd like to qualify my post by stating I am a fourth-year PhD student in Molecular Biology. Should anyone wish to correct or amplify my statement please have more expertise than having read "Hot Zone" or "The Coming Plague." Thank you.
