‘Gene Drives’ Are Too Risky for Field Trials, Scientists Say
Carl Zimmer, New York Times, November 16, 2017
International negotiations might be required before such genetically modified mosquitoes were set loose. “That’s not a question for scientists to answer on their own,” said Jason A. Delborne, a social scientist at North Carolina State University and a member of the N.A.S. gene drive committee.

New Model Warns About CRISPR Gene Drives in the Wild
Two new papers urge caution in using powerful genome-editing technology against invasive species: Models show that evolving resistance won’t stop aggressive standard gene drives from spreading.
Brooke Borel, Quanta Magazine, November 16, 2016
Among those who disagree with their assessment is Jason Delborne, one of the authors of the 2016 report and a professor of science, policy and society at North Carolina State University. While the 2016 report did suggest a stepwise approach to field tests, the authors “concluded that not enough was known to pursue an environmental release,” Delborne wrote by email.
“Arguably that has not changed,” he added. “Unfortunately, the term ‘field trial’ is not a precise concept, because its degree of risk depends upon the specifics of the technology and its context.”

The nation wants to eradicate all invasive mammal predators by 2050. Gene-editing technology could help—or it could trigger an ecological disaster of global proportions.

Excerpt:
“In 2014, Kevin Esvelt, a biologist at MIT, drew a Venn diagram that troubles him to this day. In it, he and his colleagues laid out several possible uses for gene drives—a nascent technology for spreading designer genes through groups of wild animals…”

Genetically Engineering the Natural World, it Turns Out, Could Be a Disaster
Kristen V. Brown, Gizmodo, November 16, 2017
“This is part of an ongoing conversation about the balances of risk and benefits of gene drive technology,” said Jason Delborne, a scientist who works on gene drives at North Carolina State University who was not involved in the recent work.
“These new papers signal that we should be even more cautious about gene drive technology.”
