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]
Scientists separate plasma from blood with working biochip
Disposable biotech sensors won't let you diagnose your own diseases quite yet, but we've taken the first step -- a research team spanning three universities has successfully prototyped a lab-on-a-chip. Called the Self-powered Integrated Microfluidic Blood Analysis System (or SIMBAS for short, thankfully), the device takes a single drop of blood and separates the cells from the plasma. There's no electricity, mechanics or chemical reactions needed here, just the work of gravity to pull the fluid through the tiny trenches and grooves, and it can take as little as ten minutes to produce a useful result. It's just the first of a projected series of devices to make malady detection fast, affordable and portable. Diagram after the break!
Lab-on-a-chip aims to take suspense out of blood work
If your doctor's ever uttered the words, "I'd like to run more tests," you know the wait for results can be torturous. Engineers and students at the University of Rhode Island (URI) are hoping to stop the torture with a new lab-on-a-chip technology that cuts way back on the wait for important lab results. The system provides results in 30 minutes, using a portable device and just a drop of blood. The blood is placed on a small plastic polymer cartridge, smaller than a credit card, and inserted into a shoebox-sized biosensor. It then travels across the cartridge to a detection site where reagents enable the sensor to detect biomarkers of disease. Basically, your doctor pops a bloody piece of plastic into a box, and out come your results. The first cartridges were developed to assess the risk of heart disease, but researches suggest they could be designed to detect everything from HIV to Alzheimer's. The URI team estimates costs at $3200 for the sensor and $1.50 for the test. No official word on a release date, but we hope they won't make us wait too long -- we can't stand the suspense.
Microfluidic chip does 1,000 parallel chemical reactions, looks glorious
We'd never considered a career in biochemistry until we saw this wild beast of a chemical microprocessor. Microfluidic chips, used to test chemical reactions and properties, have been known to be smaller, but they've never before been quite this powerful. The result of a joint study between California State University, UCLA and China's Wuhan University, the "integrated microfluidic device" is capable of performing 1,024 in situ chemical reactions at a time, making the researcher's life, oh, about 1,024 times easier. Most importantly though, costly enzymes previously used for a single test can now be split up into hundreds and tested simultaneously, which should pave the way for exponentially faster and easier medical research. It's not clear when these will be widely available, but we're sure PhDs around the world are trying to order one as we speak.[Via medGadget]
