FDA to Fertility Doctor: Stop Marketing 3-Parent Baby Technique

The doctor behind the technology that helped birth one of the world’s first 3-parent babies has been told by the FDA that he must stop marketing the experimental procedure.
According to the agency, John Zhang, a New York fertility doctor who helped a Jordanian couple give birth to a baby boy in 2016, had promised the FDA his companies wouldn’t use the technology in the U.S. without the agency’s permission, but they continued to promote it.

Scientists Use CRISPR to Edit Human Embryos in U.S. for First Time

A group of scientists in Oregon have edited the genes of human embryos for the first time in the United States, using CRISPR-Cas9, a cut-and-paste gene-editing tool. [1]
The experiments were conducted by Shoukhrat Mitalipov and colleagues at Oregon Health & Science University in Portland. The single-celled embryos Mitalipov edited were discarded after the experiments to ensure they could not become too developed.

In Case You Missed It: EPA Quietly Approved Monsanto’s RNAi Genetic Engineering Technology

The U.S. Environmental Protection Agency (EPA) recently and quietly approved Monsanto’s new genetic engineering technology, known as RNAi. [1]
The insecticide DvSnf7 dsRNA is not sprayed on crops. Instead, instructions for manufacturing it in the DNA of the crop itself must be encoded in crops. The plants’ self-made DvSnf7 dsRNA disrupts a crucial gene in western corn rootworms – a major threat to corn – and kills the pests.

DNA and Ancient White Egypt

A new analysis of DNA from ancient Egyptian mummies, carried out by scientists from the University of Tuebingen in Germany, has revealed that ancient Egyptians were indeed European—and that the present-day  Egyptian population is a mixed race group with a massive sub-Saharan element. The study, titled “Ancient Egyptian mummy genomes suggest an increase of Sub-Saharan…

Study: CRISPR Gene-Editing Ignites Tons of Unintentional Genetic Mutations

CRISPR-Cas9 gene-editing has been hailed as one of the biggest scientific breakthroughs of our lifetime. The technology is often called “molecular scissors” for its ability to “cut and paste” pieces of DNA, thereby removing unwanted traits and replacing them with more desirable ones. CRISPR is being celebrated for its accuracy, but a recent study sheds light on some imperfections surrounding the technology that we should be aware of.
