There is a strong suspicion that Helicobacter pylori is linked to the development of stomach cancer. Now an international team of researchers led by Prof. Donald R. Ronning (University of Toledo) has used neutrons to unlock the secret to the functionality of an important enzyme in the bacterium’s metabolism. This could be used as a point of attack for new medications. The team made the corresponding measurements at the neutron sources in Oak Ridge and at the research neutron source FRM II of the Technical University of Munich (TUM).
