A pocket-sized paper test for Ebola quickly turns from yellow to purple if someone has the disease--and no lab or refrigeration is required.
Within about 30 minutes, and without ever going to a lab, a new paper tool can tell if someone has Ebola. The current test goes much slower and requires a lab and electricity. Using a new synthetic biology technique, researchers have eliminated all those concerns and made the pocket-sized test, which can be shipped anywhere in the world and stored without refrigeration. It's both cheaper and much faster than any current Ebola tests.
