Engineered enzyme could improve detection of HIV and other viruses

10 hours 14 minutes ago
Scientists have long used a powerful gene-editing tool called CRISPR to make precise changes to DNA. But a different version of the technology, known as Cas13a, targets RNA, the genetic material found in viruses such as HIV.

The study was published in Cell Chemical Biology.
