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.
