A virus with the potential to kill up to half the world’s population has been made in a lab. Now academics and bioterrorism experts are arguing over whether to publish the recipe, and whether the research should have been done in the first place.
Researchers in Fouchier’s team used ferrets – test animals which closely mimic the human response to influenza – and transmitted H5N1 from one to another to make it more adaptable to new hosts. After 10 generations, the virus had mutated to become airborne, which means ferrets became ill from merely being near other diseased animals.
"I can't think of another pathogenic organism that is as scary as this one," Paul Keim, a microbial geneticist who has worked on anthrax for many years, told Science Insider. "I don't think anthrax is scary at all compared to this."
