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.
Apple released this lovely new commercial featuring Carl Sagan reading from his magnificent 1994 book Pale Blue Dot: A Vision of the Human Future in Space, now available as an audiobook. This surprising partnership spurred Adweek to interview my friend Ann Druyan, Sagan’s wife, collaborator, and creative director of the Voyager Golden Record, about being […]
The Action Lab took a maglev gyroscope and placed it inside a sealed chamber to see what happens to a levitating gyroscope in a vacuum. A lot of people took issue with the experiment’s setup and explanation, but it’s interesting nonetheless. He responded to those concerns: Hi everyone! I see a lot of comments that […]

As the old saying goes, “You should sit in meditation for 30 minutes every day. Unless you are too busy, in which case you should meditate for an hour.” Since most of us have an endless list of things to do and people to see, carving out quiet time can feel impossible, especially when most […]
The Bragi Dash Truly Wireless Smart Earphones are far more than your run of the mill Bluetooth earbuds. While the earpiece design makes these earbuds ideal for exercise and activity, and passive noise cancelling is conducive to a more serene listening experience, these buds go well beyond just playing music.First of all, they can actually […]
