Scientists just found a major flaw in a key COVID drug study

A promising path to fighting COVID and other coronaviruses may have been based on a serious mistake. Scientists had zeroed in on a part of the virus called the NiRAN domain, believed to be a powerful target for new antiviral drugs. But when a Rockefeller team revisited a highly cited 2022 study, they found the evidence didn’t hold up. Key molecules shown in the original virus model were actually missing. Their discovery could help prevent wasted time and resources in the race to develop better treatments—and highlights how even one bad blueprint can throw off years of research.
