Last week Lexi Carter, a black woman from Tennessee had an experience that so many other black people have had, a racially charged visit with a doctor. When Carter walked into her doctor’s office, Dr. James Turner greeted her with “Hi Aunt Jemima.” During the visit, he proceeded to call her Aunt Jemima more than once. Carter’s encounter with Dr. Turner is problematic for many reasons: 1. The term “Aunt Jemima,” which is the name of a popular syrup and pancake mix whose packaging depicts the face of a black woman, has a long history of racism dating back to the late 1800s; 2.…

US defense agencies grapple with gene drives Nature

The JASONs, a group of elite scientists that advises the US government on national security, has weighed in on issues ranging from cyber security to renewing America’s nuclear arsenal. But at a meeting in June, the secretive group took stock of a new threat: gene drives, a genetic-engineering technology that can swiftly spread modifications through entire populations and could help vanquish malaria-spreading mosquitoes.

Scientists record videos in strands of DNA using CRISPR Science

With the help of the gene editor CRISPR, scientists can now save videos in DNA, Nature writes. The researchers encoded five grayscale images into 104 DNA fragments per image, each made up of 33 DNA letters. One image per day was then introduced to the Escherichia coli bacterium. Because CRISPR adds DNA snippets to its host genome in sequential order, researchers were able to recover the recorded images after sequencing and put them together to see the movie.
