Water levels in each of these bodies have hit historic lows as the American West continues to suffer from severe…
CRISPR, the gene-editing technique that allows scientists to change DNA with remarkable ease, was discovered almost a decade ago by a couple of biologists. Jennifer Doudna and Emmanuelle Charpentier received the Nobel Prize for Physics last year for their work. Scientists all across the world have been looking at how the technique may be utilized…
