A competition between researchers is part of a $1.5 billion program that seeks to speed development of accurate, quick and easy-to-use COVID-19 tests, the U.S. National Institutes of Health (NIH) announced Wednesday. The NIH invites "all scientists and inventors with a rapid testing technology to compete in the COVID-19 testing challenge for a share of up to $500 million over all phases of development." The goal is to make millions of tests a week available to all Americans by the end of this summer, and to have even more in time for the flu season.
