NASA’s new cooling pump doesn’t need moving parts, set to chill out in space next month

It’s pretty easy to cool down an overheating desktop computer with an extra fan, but what do you do if there’s no air? That’s the hurdle NASA‘s engineers are hoping to clear with a new prototype pump that the agency unveiled last week. The pinkie-sized instrument relies upon a technology known as electrohydrodynamic (EHD)-based thermal control, which uses electric fields to inject coolant through small vents on a thermal cold plate, before moving the extra heat to a radiator and spreading it far away from any temperature-sensitive areas. With no moving parts, the lightweight cooler uses only about half a watt of power and can be sized to work with small electric components or lab-on-a-chip devices. The challenge is to make sure that the pump can survive the vibrations of a rocket launch, though NASA will put it to the test during a rocket mission on June 9 and in 2013, when an EHD thermal cold plate will be placed on the International Space Station. Start your countdown clock and blast past the break for a full press release.

NTT DoCoMo exhibits on-the-fly speech translation, lets both parties just talk (video)

The race to smash linguistic barriers with simultaneous speech-to-speech translation is still wide open, and Japanese mobile operator NTT DoCoMo has just joined Google Translate and DARPA on the track. Whereas Google Translate’s Conversation Mode was a turn-based affair when it was demoed back in January, requiring each party to pause awkwardly between exchanges, NTT DoCoMo’s approach seems a lot more natural. It isn’t based on new technology as such, but brings together a range of existing cloud-based services that recognize your words, translate them and then synthesize new speech in the other language — hopefully all before your cross-cultural buddy gets bored and hangs up. As you’ll see in the video after the break, this speed comes with the sacrifice of accuracy and it will need a lot of work after it’s trialled later in the year. But hey, combine NTT DoCoMo’s system with a Telenoid robot or kiss transmission device and you can always underline your meaning physically.

Finally, a real scientific controversy: arsenic in DNA



We spend so much time discussing manufactured controversies about science that it’s a bit refreshing to be able to report on a real one. And one has been brewing since late last year, when Science released a report that suggested that researchers had forced bacteria to evolve to the point where they no longer simply tolerated arsenic, but incorporated it into their DNA. The publication quickly attracted criticism on a few blogs that were written by scientists, leading mainstream reporters to dig into matters. Now, the scientific community is having its say in the pages of Science, with eight separate technical comments on the work.

We covered the publication when it was first released, describing the major claims of the authors. They had isolated bacteria from an environment (California’s Mono Lake) that is naturally high in arsenic, and then grew them in the lab, gradually raising the levels of arsenic while dropping those of its close relative, phosphorous, which is a component of DNA. After sufficient selection, they tested the surviving bacteria, and found some evidence that indicated arsenic may have been used in place of phosphorous in DNA.

Polymer Vision’s Rollable Flatscreen

0polymervision.jpg

While the Society for Information Display’s “Display Week 2011” doesn’t sound like the sexiest event, it was at that conference in Los Angeles that a company called Polymer Vision showed off their latest technology: A rollable flatscreen.

Polymer’s 6-inch SVGA display is 800×600 pixels and (thus far) just black-and-white, but it can be rolled into a radius of just six millimeters–meaning it would fit around a tube less than a half-inch in diameter. While integration into actual products is presumably a ways off, it’s not hard to imagine, say, scroll-shaped iPads in the future.

Europe will presumably get a look at the technology when Polymer Vision travels to LOPE-C, the upcoming Large-area Organic & Printed Electronics Conference, to be held in Frankfurt at the end of June.

Activists Destroy Scientific GMO Experiment

Freggy writes “In Belgium, a group of activists calling themselves the Field Liberation Movement has destroyed a field which was being used for a scientific experiment with genetically modified potatoes. In spite of the presence of 60 police officers protecting the field, activists succeeded pulling out the plants and sprayed insecticides over them, ruining the experiment. The goal of the experiment was to test potato plants which are genetically modified to be resistant to potato blight. It’s a sad day for the freedom of scientific research.”

The Fretlight Guitar Sets a Shining Example for Hopeful Guitar Heroes [Video]

With Guitar Hero on extended leave and no new Rock Band title coming out this year, now is the perfect time to trade in our toy guitars for something a bit more substantial. Going from five colorful plastic buttons for six strings with 22 frets each is a daunting task however, especially when music games have trained you to respond to visual cues to guide your playing; you see a green circle, you hold down the corresponding button and strum. A regular guitar won’t flash little circles in front your eyes to help you hit the right notes. More

Polymer Vision’s latest display rolls up, still doesn’t ship out (video)




Despite a litany of missed launch dates, bankruptcy filings, and corporate buyouts, Polymer Vision continues to trudge forward, and we’re more than happy to ogle its latest flexible screen. This time, the new hotness is a six-inch SVGA display repeatedly rolled-up 25,000 times at a radius of only six millimeters. The resulting scroll is apparently slightly smaller than a dime. With that kind of repetitive endurance, this tech seems well suited for building that Readius-like eReader Wistron promised a while back; not that we’re holding our breath, or anything.

ViewSonic ViewPad 10Pro boots an Intel Oak Trail CPU into Windows 7 Pro, virtualizes Android

The ViewPad 10 era is over, here comes the epoch of the ViewPad 10Pro. Beyond the introduction of Intel’s Oak Trail Z670 1.5GHz processor, the new Windows 7 Pro / Android 2.2 dual-boot tablet throws in a 3G radio, 32GB of onboard storage (expandable via MicroSD or USB), and a 3500mAh battery that’s rated to last for 4.5 hours of 1080p video playback. It’s one of Intel’s promised 10+ Android tablets coming at this year’s Computex, though it has the appreciable advantage of being able to switch over to Windows 7 pretty much instantaneously. Check it out in the gallery below and you can expect a more in-depth look from us later on during the currently ongoing Computex 2011 trade show.

Update: Calling this a dual-boot tablet may have been a little ambitious, as it’s running the Bluestacks virtualization software, which turns Android into a Windows app, rather than allowing true dual-booting capabilities.
