First 'snapshots' of the electronic structure of a manganese complex related to water-splitting in photosynthesis

Together with a large international research team, Johannes Messinger of Umea University in Sweden has taken another step toward an understanding of photosynthesis and developing artificial photosynthesis. With a combination of a x-ray free-electron laser and spectroscopy, the team has managed to see the electronic structure of a manganese complex, a chemical compound related to how photosynthesis splits water.

Twinkle, twinkle, little atom

In crystals, atoms are arranged in stable and well-order configurations that scientists can analyze with conventional X-ray techniques. However, because atoms in liquids tend to change position rapidly and don't have well-defined positions, researchers have had a hard time understanding liquid structures. A new Argonne-led study may have helped to shed some light on this problem - quite literally.

A DNA strand should be driven gently through a nanopore

It's not easy to drive long molecule chains through a nanopore because they tend to tangle up. A simulation carried out by an international group of scientists has suggested a solution: it's better to pull gently without applying too much force, otherwise the molecule could be stopped due to excessive friction.

Coming soon: Tabletop molecular movies

A group or researchers has devised and demonstrated a highly unusual, compact, and relatively inexpensive x-ray source for an imaging system that may soon be employed to produce the kind of 'molecular movies' that scientists and engineers need.
