Using high-precision quantum chemistry to study super-efficient energy transfer in photosynthesis

Credit: Ludwig Maximilian University of Munich Photosynthesis drives all life on Earth. Complex processes are required for the sunlight-powered conversion of carbon dioxide and water to energy-rich sugar and oxygen. These processes are driven by two protein complexes, photosystems I and II. In photosystem I, sunlight is used with an efficiency of almost 100%. Here […]

Large asteroid to zoom between Earth and Moon

Small asteroids fly past Earth daily, but one this size coming so close only happens once a decade (artist’s impression). A large asteroid will safely zoom between Earth and the Moon on Saturday, a once-in-a-decade event that will be used as a training exercise for planetary defense efforts, according to the European Space Agency. The […]

Life seeking ice-free refuges imitates art in Ice Age, the movie

The nunatak refuge hypothesis is that life retreated during ice ages to ice-free refuges on mountain tops (nunataks) and moraines, across the continent. Evidence for this theory comes from springtail specimens and geological records. This map of an ice-free Antarctica (a) reveals land above sea-level (green/yellow/brown). Every known springtail sampled is shown (coloured circles within […]

Credit: MASCOT / DLR / JAXA How did life come about? The answer to this question goes to the very heart of our existence on planet Earth. Did life simply arise from chemical reactions among organic compounds in a primordial soup left after Earth clumped together from space rubble? If so, where did the organic […]
