DNA-based robots promise all kinds of microscopic machinery, but there's a major obstacle: they're slow. Existing designs that use biochemical processes for movement can take hours to shuffle molecules around, which makes them utterly impractical for anything time sensitive. That might not a hurdle for much longer. Scientists have developed a DNA nanorobot (specifically, an arm) that uses electric fields to move a whopping 100,000 times faster than previous examples, even though it's based on straightforward concepts. You see, DNA molecules have negative charges as a matter of course. Researchers found that they could quickly and accurately move the arm by subjecting it to electrical pulses that tug the arm in the right direction. You can spin the arm, move it to another position or even have it apply force, all within milliseconds. You wouldn't necessarily see small numbers of these gene-based robots in action. Rather, you'd see "millions" of them ...

Kodak's big film revival isn't working out as well as planned , which leaves it in a tough spot. How is it going to spark interest and raise a ton of cash in a hurry? Easy -- hop on the cryptocurrency bandwagon . The former legend has partnered with Wenn Digital to launch a KodakOne image rights platform that takes advantage of KodakCoin, a photo-centric virtual currency. In theory, the monetary format creates a reliable photo economy -- the distributed trust of blockchain ensures you get paid instantly and securely the moment someone buys your pictures. KodakOne, meanwhile, continuously crawls the web looking for copyright violations. The initial coin offering debuts on January 31st for accredited investors in the US, Canada, the UK and a handful of other countries. There is a practical advantage to Kodak's approach. Ask any pro photographer and they'll tell you that they hate waiting for payments. However, it's no secret that many companies have been using c...
