Usually, harvesting energy and raw materials from plants requires many process steps and aggressive chemicals. To make these processes more efficient and resource saving, researchers are looking for suitable enzymes. Using neutrons, researchers have now investigated the reaction mechanism of an important class of enzymes: the glycosidases.

Read moreEstimates suggest that biomedical research consumes almost a quarter of a trillion US dollars every year, yet according to some studies up to 85 per cent is avoidably wasted. Examples of waste include the non-publication of research, failure to share data and instances where the results of research are untranslatable to the benefit of patients or the efficiency of health care delivery.
