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.

Climbing robot can scale walls on a supersonic stream of air, won't leave fingerprints behind
There are plenty of wall climbing robots roaming the Earth, but few can scale heights as gracefully as this little guy can. Developed by researchers at the University of Canterbury in New Zealand, this bot can wind its way across any glass, metal or cloth terrain, without even touching its pods to the surface. The secret lies in Bernoulli's Principle, which states that as the speed of a fluid increases, its pressure decreases. This phenomenon also applies to streams of air, which, when moving at high speeds around of a circular gripper, can create a vacuum strong enough to hold things without actually touching them. In this case, air shoots out of the robot's feet at more than 2,000 miles per hour, creating enough pressure to lift the craft, while holding it close to the wall. The technology isn't new, but rarely can it support the weight of an entire device -- let alone the extra cargo that this climber's non-contact adhesive pads can hold. Researchers say the supersonic grippers will be available in "some months" and will probably cost "a few hundred dollars." As for the bot itself, Canterbury's engineers envision it being used for industrial inspections -- though the more we think about it, the more we realize just how dirty our windows are.

Breakfast Topic: How do you make time for working out?
This Breakfast Topic has been brought to you by Seed, the Aol guest writer program that brings your words to WoW Insider's pages. A recent NPC comic strip touched on an issue I find very near and not quite dear to my ... mid section. It has one of the main characters admitting he's gained some weight; he then suggests that a rule be enacted that he cannot play WoW until he has worked out. Sounds simple, right? Some would say that depends on your level of self-control and willpower. Having tried this rule myself, I also say it depends on your raid schedule, your work schedule and any unexpected overtime, the traffic levels on your drive home, what's for dinner ... There is so much to this balancing act that such a rule is tough to keep in place. Do you make 24 people counting on you to be in a raid wait for you or replace you while you do your workout regimen? An obvious rebuttal: Work out in the morning! Well, as the comic strip characters find out, that doesn't always pan out either. On a regular day I get up at 5 a.m., which is plenty early enough for me without a workout on top of it. How do you balance your gaming habits and health concerns? Do you work out in the morning? Do you have a rule in place as the comic characters did, that you can't play til you work out? Or perhaps you're one of the lucky people who just have a high metabolism? /jealous
Physicist fight: how heavy is a kilogram?
Physicists are currently hotly debating a topic some of us never think about -- or if we did -- surely we'd think 'there's an answer for that, even if I don't know what it is.' The question? The question at hand is 'how heavy is a kilogram?' The currently accepted answer is the mass of a cylinder of platinum and iridium called the International Prototype Kilogram. The problem with that definition, of course, is that not just anybody can measure it -- since most of us don't have an International Prototype Kilogram laying around, especially since every time the thing is picked up a few atoms rub off of it making it a little bit lighter. Because of this, the actual International Prototype Kilogram (yes, there does only seem to be one in existence) is stored in a vault in Sevres, France, limiting the lay person's ability to determine the actual weight of a kilogram. There are other options on the table, of course, including one involving a two-stories high piece of equipment that costs around $1.5 million -- which isn't much better, when you think of it. Enter Ronald Fox and friends over at the National Institute of Standards and Technology. They're suggesting a rather shocking solution: make the kilogram equal to the mass of a certain number of carbon-12 atoms (2250× 28148963^3 of them), also known as a cube of carbon measuring 8.11 centimeters on each side. This would mean, of course, that pretty much anybody could determine the weight of a kilogram at home. But we wouldn't want that, now, would we?
Switched On: The weighty issues of slates
Each week Ross Rubin contributes Switched On, a column about consumer technology. Slates may seek to occupy a device class in between smartphones and notebooks, but they have their own dynamics. If the closest real-world counterpart for the PC was the desktop, the closest real-world counterpart for the slate may be the clipboard, a platform that aggregates and recalls important resources on the go but isn't something most people need access to all the time. And with the change in usage comes different design priorities. Like a laptop, slates will be judged on factors such as speed, screen size, and battery life. But one spec that will take on new significance compared to other mobile devices is weight. This stems from the slate's unique hybrid of smartphone and notebook usage scenarios. The natural limits of the size of smartphones put a de facto upper limit on how heavy they can be. A few ounces isn't going to make a big difference in arm fatigue, even for most calls; there are Bluetooth headsets to alleviate longer ones. And the nature of smartphone apps also tends to favor short usage sessions.
