With the help of directed evolution, scientists inch closer to developing viral vectors that can cross the human blood-brain barrier to deliver gene therapy.
Different variants of the virus behind the COVID-19 pandemic are swapping chunks of genetic material, but it’s not yet clear what implications that may have for public health.

Researchers find that surges in COVID-19 case numbers are associated with deletions in the SARS-CoV-2 genome in an antigenic site of the spike protein. Some of these mutations are present in vaccine breakthrough infections or reinfections.
Scientists across the world are closely tracking the spread of mutations in the coronavirus and investigating whether they could render current vaccines less effective.
