Introduction:
Additional extract:(IFL Science) Agroup of bat coronaviruses closely related to the virus behind Middle East Respiratory Syndrome (MERS) could be only a small mutation away from spilling over into the human population. Should that happen, we may find ourselves facing the next coronavirus pandemic.
Until recently, there hadn’t been all that much attention paid to the merbecoviruses, a subgenus of coronaviruses that includes MERS-CoV. In their latest study, a team led by Washington State University virologist Michael Letko, with colleagues from Caltech and the University of North Carolina, wanted to take a deeper look at this neglected group.
“These viruses are so closely related to MERS, so we have to be concerned if they ever infect humans,” said Letko in a statement. “While there’s no evidence they’ve crossed into people yet, the potential is there – and that makes them worth watching.”

This is the same receptor exploited by SARS-CoV-2.
Using the Nobel Prize-winning AI tool AlphaFold, the scientists modeled how this molecular interaction may happen, and how antibodies might block it. This kind of work used to take months before the advent of AI.
