There continue to be reports of new attempts to create life, sometimes labeled “synthetic” or “artificial” because the entity is not created the old-fashioned way, i.e., by fertilization of an egg with a sperm. The most recent report involved combining two different types of stem cells to form an embryo-like structure that was labeled “artificial.”

Conducting research on embryos beyond 14 days’ gestation is against the law in 12 countries, including the United Kingdom; the U.S. has only “guidelines” recommending the 14-day limit. Now researchers and others are pushing against that limit. They find it too confining. Where did this rule/guideline originate?

Sometimes what seems like science fiction can actually be science fact, and sometimes new technologies can have the potential for both good and bad uses. So-called “dual-use technology” is most often thought of in connection with potential military as well as civilian use, e.g., weaponized forms of viruses or bacteria vs. using such altered pathogens for vaccine development.

Science fiction is no longer fiction—the first three-parent baby was born a few months ago. Last month in The Point, Dr. Robert E. Cranston raised a series of important questions about the safety and ethics of the technique; now more information—and more questions—have arisen. As a reminder, the concept of creating a baby with three parents came as a proposal to “treat” individuals with mitochondrial genetic diseases, i.e., mutations in the mitochondrial DNA that lead to sometimes lethal physiological problems.
