AI Created New Viruses — What It Means for COVID, Medicine, and the Future

Scientists used artificial intelligence to design genetic codes that produced functioning viruses never before found in nature. They infect bacteria, not humans—but the breakthrough raises an obvious question: could we someday design a virus that infects people? Dr. Terry Simpson explains what scientists accomplished, why we could not do this in 2019, and what it does—and does not—tell us about claims that COVID-19 was designed. Plus, measles costs millions, Cyclospora declines, the first mRNA flu vaccine arrives, and new studies examine testosterone, dementia, vitamin D, vegan diets, and tirzepatide.
