Google attempts to protect users from sketchy stem cell clinics

Enlarge / Google logo seen during Google Developer Days (GDD) in Shanghai, China, September 2019. Transplanted stem cells can be as lifesaving as donated organs, but the Food and Drug Administration in September warned consumers that some stem cell clinics only pretend to be in the business of miraculous recoveries. Now, Google is attempting to…

BSIP/Universal Images Group The last antibiotics generated against Gram-negative bacteria—which tend to be the more dangerous type—were developed in the 1960s. Thanks to the rise of antibiotic resistance, we need more. But rather than going through the trouble of trying to make our own, scientists have looked to other species that might need to kill…

Single response mix can produce all 4 RNA bases

Simple chemicals can grow complex pretty quickly. There's a strong consensus that life on Earth got its start through RNA, a close chemical sibling of DNA. Over the last few decades, researchers have described how individual RNA bases can spontaneously polymerize, forming longer chains that could ultimately catalyze key chemical reactions, including building even longer…
