Respiratory virus infection triggers new class of biomolecules

( -- For the first time, scientists have discovered that a poorly understood class of RNA produced in a mammal's cells during a respiratory virus attack may affect the outcome of the infection. Their findings ...

Jumping hurdles in the RNA world

Astrobiologists have shown that the formation of RNA from prebiotic reactions may not be as problematic as scientists once thought.

What types of nucleic acids existed before RNA and DNA?

Structure generation software allows scientists to begin exploring the types of nucleic acids that could have existed before, alongside, or indeed instead of, ribonucleic acid (RNA) and DNA.
