Bacteria and Archaea have developed many types of CRISPR-Cas systems to protect themselves from viruses. A search through metagenomic databases of microbes, many of them uncultivatable, unearthed the genes of the smallest known working Cas complex, Cas14, from the genome of a DPANN Archaea, a group of microbes with the smallest known geomes. Cas14 is being incorporated into a CRISPR diagnostic called DETECTR. Full Story

The U.S. National Science Foundation propels the nation forward by advancing fundamental research in all fields of science and engineering. NSF supports research and people by providing facilities, instruments and funding to support their ingenuity and sustain the U.S. as a global leader in research and innovation. With a fiscal year 2021 budget of $8.5 billion, NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and institutions. Each year, NSF receives more than 40,000 competitive proposals and makes about 11,000 new awards. Those awards include support for cooperative research with industry, Arctic and Antarctic research and operations, and U.S. participation in international scientific efforts.
