  • The first coronavirus vaccines will enter Phase 2 testing soon but won't be ready for another 18 months.
  • Synthetic biology may offer a "universal coronavirus vaccine" that can be quickly modified to combat future mutated forms.
  • Despite promising lab tests, synthetic vaccines remain speculative; we'll need to live with COVID-19 during the interim.

  • The central dogma of biology states that genetic information flows from DNA to RNA to proteins, but new research suggests that this may not be the only way for life to work.
  • A sophisticated computer analysis revealed that millions of other molecules could be used to function in place of the two nucleic acids, DNA and RNA.
  • The results have important implications for developing new drugs, the origins of life on Earth, and its possible presence in the rest of the universe.
