A fast, needle-free malaria detection tool developed by a University of Queensland-led team could help save hundreds of thousands of lives annually. Malaria is usually detected by a blood test, but scientists have devised a method using a device that shines a beam of harmless infrared light on a person’s ear or finger for five-to-10 seconds, it collects an infrared ...

Stanford University scientists have described a new type of test that can detect genetic mutations in minute amounts of DNA released from cancer cells into the blood. The test, which is called single color digital PCR, requires only a fraction of a tube of blood and can detect as few as three mutation-bearing molecules in a single reaction. According to ...
