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.
Three scientists won the world’s top science prize today, for their “mechanistic studies of DNA repair.” Their work mapped how cells repair deoxyribonucleic acid (DNA) to prevent damaging errors from appearing in genetic information. Tomas Lindahl, Paul L. Modrich and Aziz Sancar today received the Nobel Prize in Chemistry for “having mapped and explained how […]
Maciej Ceglowski (previously) spoke to a O’Reilly’s Strata Big Data conference this month about the toxicity of data — the fact that data collected is likely to leak, and that data-leaks resemble nuclear leaks in that even the “dilute” data (metadata or lightly contaminated boiler suits and tools) are still deadly when enough of them […]
Some day, you may be the defendant in a criminal trial that turns on whether the software in a forensic device reached a reliable conclusion about a DNA test or other piece of evidence. Wouldn’t you like to have your own experts check the source code on that device?
