A 20 cent paper centrifuge to test for diseases

Stanford University researchers have developed a vastly lower-cost alternative to traditional centrifuges. For approximately 20 cents (rather than hundreds or thousands of dollars, and without the need for power), a paper device could allow health workers in the field, in remote areas without power, or after natural disasters do on the spot testing for diseases such as malaria, tuberculosis and HIV.
