  • 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. [Thanks, Kevin]

  • Versus and Golf HD get their own channel, and E! HD on the way

    Versus and the Golf Channel have been sharing an HD channel for some time and both have evidently graduated to the point that they're getting their own channel. This seemed like a pretty good combo to us, as we don't see much golf on at night, but we suppose some want to watch bicycle races during the day. What isn't very clear is if the current carriage deals will need to be reworked, of if everyone who has the combo now will automatically get the two dedicated channels when launched. On a who cares note -- E! is getting the HD treatment which we'll file right up there with Lifetime HD, but hey, at least maybe it'll help some poor sap talk his wife into a new HDTV.
