A new pressure cell makes it possible to simulate chemical reactions deep in the Earth’s crust. The device could allow insights into deep-Earth chemistry and carbon cycling, ‘fracking’ and nuclear waste disposal.
Scientists have solved a long-standing mystery in biology, by identifying the molecular structure of a vital biological chemical. The debate — which has raged within the scientific community for years — boils down to something as simple as a hydrogen atom: is it there, or is it not?
Scientists have taken the first snapshots of photosynthesis in action as it splits water into protons, electrons and oxygen, the process that maintains Earth’s oxygen atmosphere. The revealing of the mechanism of this water splitting process is essential for the development of artificial systems that mimic and surpass the efficiency of natural systems.
