What the ban on gene-edited babies means for family planning

A ban on clinical trials involving gene editing rules out the controversial procedure done in China. But it also prevents procedures that could offer couples a chance for healthy children without genetic disorders.
Home DNA testing has made it easy and affordable for millions of people to learn about their ancestry. Now, police are using this genetic information to identify suspects in unsolved crimes. Shutterstock

Privacy concerns don’t stop people from putting their DNA on the internet to help solve crimes

Despite privacy concerns over police use of DNA uploaded to ancestry websites, many people are just excited that their genetic material could get a killer off the streets.

Gene-edited food regulations: whether it’s a plant or animal shouldn’t matter, but it does now

According to current regulations, animals that have been genetically edited, like pigs or cows, are considered drugs. What are the consequences of such rules on American livestock and agriculture?
