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 […]

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 […]

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 […]

In the Future, You Won’t Need Two Parents to Make Babies

There are test-tube babies and three-parent babies, and both generate plenty of controversy. But as it stands, making a baby still requires an egg from a mother and sperm cells from a father. Scientists say that won’t always be the case, though, because someday it will likely be possible to make babies from skin cells […]
