With the new “super-microscope”, MAX IV, we are now able to zoom in directly on the molecular building blocks of tiny airborne particles. We can see not only the building blocks themselves, but also how they are organized inside the particles. This new knowledge could provide a window into the hidden workings of climate change.
A study of an enzyme that helps build and repair DNA in living organisms increases our understanding of how these processes are controlled and how we can use this to combat infections. Chemists at the Faculty of Science at Lund University in Sweden, together with their colleagues in Umeå and Stockholm, have studied the enzyme ribonucleotide
