  • Understanding the evolution of viruses

    Viruses have always had a major influence on life. They emerged a few billion years ago, precisely when is difficult to estimate. There are also several theories as to how viruses originated. While exploring one possibility, researchers at ETH Zurich have managed to recapitulate a potentially pivota more

  • A New RNA Catalyst From the Lab

    Enzymes enable biochemical reactions that would otherwise not take place on their own. In nature, it is mostly proteins that function as enzymes. However, other molecules can also perform enzymatic reactions – for example ribonucleic acids, RNAs. These are then called ribozymes. In this field, the r more

  • Prebiotic chemistry - In the beginning, there was sugar

    Organic molecules formed the basis for the evolution of life. But how could inorganic precursors have given rise to them? Ludwig-Maximilians-Universitaet (LMU) in Munich chemist Oliver Trapp now reports a reaction pathway in which minerals catalyze the formation of sugars in the absence of water. Mo more
