Zika Test Cut-Away (IMAGE)

The researchers developed a type of genetic assay that only requires a sample to be kept at a consistent temperature, rather than cycled through a number of careful temperature changes. They then worked on how to keep the sample at the necessary temperature without using electricity. Their solution involved a thermos bottle, a self-contained heating element that uses a chemical reaction from portable military rations and a wax-like material that absorbs excess heat by melting. A 3-D printed lid fits on top of the thermos and holds all of the test's components in place.
