CRISPR kills HIV and eats Zika 'like Pac-man'. Its next target? Cancer | WIRED UK

Read the full article:  CRISPR kills HIV and eats Zika 'like Pac-man'. Its next target? Cancer | WIRED UK:

"These new enzymes are variants of a CRISPR protein, Cas13a, which the UC Berkeley researchers reported last September in Nature, and could be used to detect specific sequences of RNA, such as from a virus. The team showed that once CRISPR-Cas13a binds to its target RNA, it begins to indiscriminately cut up all RNA making it "glow" to allow signal detection."

FDA finds herbal supplements at GNC, Walmart, Walgreens, and Target contain asparagus, houseplants, and no herbs | Inhabitat - Sustainable Design Innovation, Eco Architecture, Green Building

Read the full article: FDA finds herbal supplements at GNC, Walmart, Walgreens, and Target contain asparagus, houseplants, and no herbs | Inhabitat - Sustainable Design Innovation, Eco Architecture, Green Building:

"The New York State Attorney General’s Office is demanding that GNC, Walmart, Walgreens, and Target remove store brand herbal supplements from their shelves after the pills were found to be packed with a strange array of fraudulent—and in some cases hazardous—ingredients. Popular supplements such as ginseng, valerian root, and St. John’s wort sold under store brand names at the four major retailers were found to contain powdered rice, asparagus, and even houseplants, while being completely void of any of the ingredients on the label."

FDA Final Guidance On Genetically Engineered Animals

The procedure of genetic engineering uses recombinant DNA for introducing new characteristics or traits into an animal. The new guidance, Guidance for Industry #187 - Regulation of Genetically Engineered Animals Containing Heritable Recombinant DNA Constructs, provides all the needed details, so that the producers of these animals will know what to do in order to get the FDA's approval. Moreover, producers of these animals will also have to follow the law and regulations of the National Environmental Policy Act. I think these are truly remarkable times in the life of scientific discovery. Do you find these advances astounding or troubling?
