For years, particle physicists and computer scientists have been promising us vastly improved memory chips based on the spin of individual electrons, but concrete advances have been awfully elusive. Now a team at Ohio State has put together a working device to test spintronic memory, and used it successfully.
The team hooked a pair of leads to an array of magnets, and, by manipulating the spin of the electrons within the magnetic fields, were able to record and retrieve data.
Spintronics promises to double the density of computer storage, as each electron will be able to store two bits of data instead of one. Energy usage will drop as well, since the electrons won't need to flow around to do their work. The result would be smaller devices with smaller batteries.
io9 quotes Arthur J. Epstein, a researcher on the project: "If we had a lighter weight spintronic device which operates itself at a lower energy cost, and if we could make it on a flexible polymer display, soldiers and other users could just roll it up and carry it."
I helped out on spintronics research in college for a semester, didnt really understand what was going on though, I was mostly just the "hey go get my coffee" guy
"soldiers and other users could just roll it up and carry it." awesome. Good to know the cutting edge of science is dedicated to more effective killing.
In other news, humans share 96% of their DNA with chimpanzees.
Wow that is such a fascinating story, thanks for sharing Michael Taylor.
oooooookkkkkkkk mister negative PaulAdams, you should unwrap your arms from that tree and experience life outside of your college, FOR GOD-SAKES AT LEAST OPEN THE DRAPES!!
on another note very interesting article very cool to see this technology revolution unfolding, gratz guys keep it comin :)
Great can they be massed produced without adding toxic byproduct to the environment.
Making all this super technology is awesome but i never hear whether anyone of these products are being made with products that can be recycled or break down in the environment without a negative return.

You are so incredibly sad. It's really too bad that you've let the media and Wikileaks color your perception of the Military. We've done more in the last few years to save lives than any other organization.... Not sure if you remember disasters like Hurricane Katrina, or the earth quake in Haiti. Imagine what a screen like that would do to help us find victims beneath rubble or trapped in houses? Next time, don't beleive the hype and think before you type.
You make an excellent point.
We need advanced technology without
ecological "side effects".
One day not so many years from now people will be able to look back on enviromentalism and LOL about it so much like the pet rock fad, it too will be recognized as a money making gimick.
@friedguy - Really?! So here is what I get from your post:
To you preserving our home planet is a bad thing.
Thinking forward to produce goods that won't last in landfills for thousands of years is a bad thing.
Doing what we want when we want because we can no matter how much it damages the environment is an okay thing to do because environmentalism is nothing but a joke.
Sure, there are some crazy environmental extremists out there, and even if global warming etc turns out to not be as bad as predicted, we at least would have made HUGE strides to better our planet, the environment and OUR health.
But for you, you're okay with living in a polluted dumb, so enjoy that landfill you call home.
@lax4ever & @friedguy
I partially agree with both of you, we should do what we can to preserve and use our resources wisely, BUT we shouldn't turn it into a religion, aka Environmentalism. I believe that the climate has been changing, however not at the cause of humans. there is a solar cycle that affects the average temp. on Earth, going up about 11 years then down the same amount, so i'm not into the great 'Global warming" disaster scenario.
Pollution is bad, period. No one wins, many lose. However, we have to be willing to take some risks so that we can advance our knowledge. We shouldn't bind ourselves by 'ecosafe' technology, that would be cutting out our knowledge of what WOULD hurt the environment and ways to make it less harmful to it. Failure isn't bad, It's a learning opportunity. Take the recent oil spill for example. Everyone said it was gonna be the worst oil disaster in ages, then after it was finally caped, three fourths of the total estimated oil disappeared. Gone. I'm not saying that this wasn't a disaster, but a lesser one than it might have been. And guess what :) we learned a hundred ways how not to cap a leaking oil well, and found one way that appears to work well. Now we have an idea of how to handle future oil spills more quickly and efficiently.
Also, while we are holding back our science research and slowing the development of our own resources, other countries who could care less about the environment are moving forward, and might push past us. That won't be good. We don't want to keep depending on other countries for our energy and resources when we have our own at home! It's stupid! We can find a safe pollution free way of using and making our own, if we let ourselves :)
regardless of weather its all hype partially true or al gore is correct and were all gonna burn up in 10 years from the green house effect, what you should all consider is this, this global warming/enviromentally friendly thing/farce/fact is providing more money for world wide R&D than has been seen since the last great technology leap in the industrial revolution, and is in many ways a good deal responsible for alot of the breakthoughs that we read about in this magizine (and many more that we do not) so i say, good/bad right/wrong lies/truth, all and all you cant beat progress
Isnt this amazing how quickly Humans advance through our technology.
When will this be put into Personal Computers?
"the" michael taylor from grande prairie?
Very cool. I really don't know if we need "smaller," though. Holographic interface would be sick. Let's do that.
Well now we don't have to worry about dropping them
Smart people breed less.
