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.
Designer Art Donovan writes, “I’m always looking for new and unique inspiration for my lighting commissions and the latest, cutting edge scientific devices offer a boatload of great design inspiration. From the cool, new ‘James Webb Space Telescope’ to the myriad of complex details in the L.H.P.C. at Cern- it’s a cornucopia of rich imagery.”
In 2009, President Obama pledged to “restore science to its rightful place.” He said, “We will not just meet, but we will exceed the level achieved at the height of the space race, through policies that invest in basic and applied research, create new incentives for private innovation, promote breakthroughs in energy and medicine, and […]

Some truths are universal. For one, your phone will always run out of power when you most need it. For another, the charging cords that come packaged with your Apple device will fray, split, and rip faster than Usain Bolt in a game of tag.Instead, pick up a charging cord that anyone would have a tough […]
Some people say magic tricks are nerdy and best left to your 12-year-old asthmatic cousin. But others see value in perfecting the slight of hand and showmanship associated with a perfectly executed routine. We’re firmly in the latter camp. And now, we’re giving you the ability to put a few parlor tricks up your sleeve with the Penguin […]
