''' DESIGNER BABIES DEBATERS '''

SCIENTISTS HAVE DEVELOPED AN ' Embryo-Editing ' technique that meticulously swaps out individual letters of the genome safely. The tool may help wipe out diseases - but could most easily trigger rush towards enhancement.

When scientists in Columbia University announced they had used a newer technology to precisely edit the genes of human embryos earlier this month, they set the academic community ablaze with debate.

Is this good news or bad? How fast will this move ? And more philosophically :

Where does medicine end and eugenics begin?

The results of the new study first reported by The New York Times, showed that a technique called base editing meticulously swapped out individual letters in the embryo's genome, altering genes linked to fetal hemoglobin production, cholesterol levels and the risk of heart disease.

Though the work is still under peer review and has not yet been published in a scientific journal, experts from a vast array of disciplines are discussing whether the tool will bring us one step closer to curing inherited diseases or one step closer to designer babies or both.

Optimistic clinicians saw the Columbia study as a major step in medicine, bolstering their hope that scientists could one day fix embryo mutations in a clinical setting.

Dr. Ellen Goldstein, a reproductive endocrinologist and fertility specialist in Los Angeles, said that for some of her patients, the tool could mean a successful pregnancy with an embryo that would have otherwise been discarded.

'' These very specific problems that the technology could be applied to - conditions where we all agree there are devastating consequences,'' she said, like Huntington's disease.

Huntington disease, which causes nerve cells in the brain to break down, or Duchenne muscular dystrophy, in which skeletal and heart muscles waste away.

As a doctor, '' You wish you could just go in and start fixing embryos,'' she said.

Tweaking embryos with an earlier form of of gene editing, CRISPR, is considered far too risky. The tool functions like a pair of molecular scissors, hacking off long segments of DNA, sometimes in error.

Researchers who tried it found their specimens with strange DNA rearrangements, with large swaths of missing and, in some cases entire chromosomes destroyed.

Base editing is not nearly as clunky. The Columbia researchers were in many cases able to change single letters of the genome safely, as if they had a precision eraser and a red pencil to simply correct the spelling.

For proponents of the new tool, the argument is : If we could safely prevent a child inheriting a devastating genetic condition, isn't it unethical not to?

'' We have to be really careful not to have knee-jerk reactions to reject this kind of research " Dr. Goldstein said,  '' as long as you're doing it with proper understanding, and proper respect for the future implications and with correct oversight from biologists and ethicists.''

Many of these ethicists are the one issuing caution. Dr. Lainie Friedman Ross, a pediatrician and bioethicist at the University of Rochester, was skeptical not just of the future implications of the technology, but of the present day work.

'' Let us be clear, '' she said. '' Human embryos become living human persons. The research is being done on future persons without their consent. ''

The researcher who led the project, Dieter Egli, told The Times that a public conversation about the pros and cons of editing genes in embryos was necessary, but that, '' as a scientist, you can provide the data for discussion, but then essentially there you stop and let others take over.''

Dr. Ross vehemently disagreed. '' This is morally irresponsible. There is no such thing as value-neutral science, '' she said. '' The team has already made an ethical decision to pursue this line of work. ''
