The Chemistry in 2050–Space webinar brought together leading scientists to discuss how chemistry is essential for understanding the universe, from the origins of life on other planets to the ...

We have found amino acids in meteorites, hints of nucleobases, the genetic code letters, but the results were always suspect, because we know that as soon as a meteorite lands on earth, it gets ...

In this work we highlight the potential of NEXAFS—near-edge X-ray absorption fine structure—analysis to perform refinements of hydrogen-bond structure in DNA. For this purpose we have carried out ...

The spontaneous formation of RNA polymers is a fundamental yet challenging step for the origin of life. Here we show that 2′,3′-cyclic nucleotides of all four nucleobases efficiently polymerize ...
