Freeze! Scientists film proteins at work by freezing them at different states

...ied the right states, they studied the sample with synchrotron x-rays. We expect this new methodology to be of use for many researchers in the field, Bourgeois explains. Filming certain proteins whilst reactions occur has been possible at the ESRF for some years. However, experiments until today were restricte...

"We now have a structural basis with which to understand the different stages of reactions in the process that uses sunlight to split water," says Messinger. "This is an important step towards developing artificial catalysts for regenerative ...

Mind the gap

...erfaces. This is the first time that high energy synchrotron X-rays have been used as a tool to measure the properties of this gap. "Some teams have used neutrons, but they didn't have enough resolution, after all, the gap is extremely small and difficult to track," explained Harald Reichert, the papers corres...

Bones at the nanoscale

...cale takes place in a bone by studying it with the synchrotron X-rays. This study explains the enor-mous stability and deformability of bones. The hierarchical structure of bones makes them able to sustain large strains without breaking, de-spite being made of essentially rigid units at the molecular level. The ...

Dartmouth study contributes to research addressing malnutrition and iron deficiency

"This technique is noninvasive and requires no sample preparation. We think our work will open the way for many more biologists to use this technique to examine the spatial dis...

Unique imaging uncovers the invisible world where surfaces meet

...e what she could not with a normal microscope. The synchrotron emits energy at all spectral frequencies, from infrared (IR) to X-rays. The light emitted by IR, which is what Hirschmugl uses, is intense, but not visible with the human eye. IR reveals the vibrations of molecules in a cell, which act as "signature...
