Researchers in George Church’s lab modified wild type ADK proteins (left) in <em>E.coli</em>, furnishing them with an nonstandard Amino Acid (nsAA) meant to biocontain the resulting bacterial strain.

Akos Nyerges uses MAGE to genetically protect E. coli from invading phages and prevent those modified genes from escaping into the environment.

Several cycles of MAGE can introduce edited segments of genetic information to multiple targets in a genome, as well as promote the growth of a diverse population of cells in a colony or swap out amino acids in polypeptide chains.

SSAPs work with a host’s existing single-strand binding proteins to edit single-strand portions of DNA. Using SSAPs to bind edited genes during replication produces a new generation of edited cells, which can be scaled up using the MAGE system.

George Church is at it again, this time using multiplex gene editing to create virus-proof cells, improve organ transplant success, and protect elephants.

Legislation now allows some drugs to skip animal testing, but it&rsquo;s unclear when, if ever, this step will be gone for good.

Animal testing might go, but not today
