Eric sez, "Australian scientists developed a cheap blood test for African sleeping sickness and gave it away under a Creative Commons license."
Zablon Njiru and Andrew Thompson of Murdoch University led a team that developed the elegantly simple way to check for trypanosomes -- protozoan parasites that are sometimes carried by tsetse flies.
To catch an infection in the earliest stages, when it is most treatable, technicians must look for a very small number of parasites in a sea of body fluids. That is not an easy thing to do, but there is a trick to make it easier: By mixing the liquid sample with a cocktail of molecules that can copy trypanosome DNA, they can make the serum resistance associated gene, a signpost of the disease, stand out -- transforming each test into a manageable task.
Instead of using the polymerase chain reaction, which amplifies the microbe DNA with the aid of an expensive instrument called a thermocycler, the researchers employed another gene multiplying technique called loop-mediated isothermal amplification. It requires little more than a warm water bath and a few chemicals. After that procedure, which takes less than a half hour, the scientists can simply add some SYBR green dye and watch the brew change color if it contains a boatload of duplicated genetic material from the pathogen.
Researchers at UC Riverside and Centro de Investigación Científica y de Educación Superior de Ensenada have published a paper describing their ongoing success in setting a “transparent nanocrystalline yttria-stabilized-zirconia” into patients’ skulls, which reveal the patients’ brains so that the patients’ brains can be zapped with therapeutic lasers.
One million miles from Earth, hanging in space between Earth’s gravitational pull and the sun’s, is the DSCOVR satellite and NASA’s incredible EPIC camera. Every two hours, EPIC takes a photo of Earth “to monitor ozone and aerosol levels in Earth’s atmosphere, cloud height, vegetation properties and the ultraviolet reflectivity of Earth.” The above video […]
In Botswana, conservation scientists from the University of New South Wales are painting eyes on the rear ends of cattle in an effort to deter lions from eating them. As the lions’ protected habitats shrink, they move closer to human settlements. In Botswana, the lions attack the livestock that the subsistence farmers count on. That […]
3D printers are hot, but they’re also pricey. While the prospect of cranking out everything we can dream up is enticing, cost is often one factor that keeps us from jumping onto the 3D printing train.Now, thanks to M3D, that doesn’t have to be the case. You can now get its flagship 3D printer–plus four reels of filaments–for just […]
It’s no secret that technology is changing the way we all work—but it’s also transforming the way we play. The games of today look nothing like those of 10 or even 20 years ago: these days it’s all about mobile and 3D. And now you can learn to design 3D mobile games with the Intro to Unity 3D Game […]
