The Dark Side of CRISPR

Its potential ability to “fix” people at the genetic level is a threat to those who are judged by society to be biologically inferior

Scientific American

Sandy Sufian, Rosemarie Garland-Thomson

Americans have celebrated the fact that the Biden administration is embracing science and returning the country to evidence-based policymaking. We agree that science should guide policy—except in cases where it wouldn’t assist people to live their lives but would, instead, exclude them.

The CRISPR-Cas9 gene-editing technology, for which biochemists Jennifer Doudna and Emmanuelle Charpentier won the Nobel Prize in Chemistry, has the potential to do just that. So do other forms of scientific technologies. We should therefore always be aware of the ethical choices these technologies can pose. . . continue reading

Is Reducing Down Syndrome Births a Form of Eugenics?

We are still choosing who lives and who dies based on genes.

Psychology Today

Richard Gunderman

A recently released study finds that Europe has reduced the number of babies born with Down syndrome by 54%. In 2016, the same researchers found that the U.S. rate of Down syndrome births had declined by 33%. Some friends and colleagues have asked me whether such reductions, which entail prenatal diagnosis and elective pregnancy termination, mean that we are still practicing some form of eugenics.

Down syndrome is a genetic disorder usually associated with an extra copy of chromosome 21 – hence its other name, trisomy 21. Children with Down syndrome generally exhibit growth delays, reduced intelligence, and a shortened life span of around 60 years. The risk of having a baby with Down syndrome increases with parental age. When prenatal testing reveals the diagnosis, some parents, including apparently many in Europe and the US, elect to terminate the pregnancy. . . [Full text]

Is it ethical for deaf parents to choose to have deaf children?

BioEdge

Michael Cook*

. . . There is a growing body of literature to support the right of deaf parents to use pre-implantation genetic diagnosis (PGD) to select for deaf children. Jacqueline Mae Wallis, a philosopher at the University of Bristol (UK), contends in the journal Medicine, Health Care and Philosophy that this is morally permissible. . . [Full text]

Scientists Attempt Controversial Experiment To Edit DNA In Human Sperm Using CRISPR

Rob Stein

First it was human embryos. Now scientists are trying to develop another way to modify human DNA that can be passed on to future generations, NPR has learned.

Reproductive biologists at Weill Cornell Medicine in New York City are attempting to use the powerful gene-editing technique called CRISPR to alter genes in human sperm. NPR got exclusive access to watch the controversial experiments underway. . . [Full text]

He did it: uproar over Chinese gene-edited babies

BioEdge

Michael Cook

A Chinese scientist has faced widespread condemnation for editing the genome of two babies at his lab in the Southern University of Science and Technology in Shenzhen, together with an American colleague.

The researcher, He Jiankui, outlined his work at the Second International Summit on Human Genome Editing in Hong Kong. His experiments have not been peer reviewed or published so it is impossible for other scientists to verify his claims. In a Q&A session, He came under heavy fire from other scientists. . . Full text
