The highly acidic environment in the stomach is essential for digestion. Furthermore, it acts as an important barrier to invasive pathogens. However, excessive stomach acidification leads to ulcers.

Physicists used MINERvA, a Fermilab neutrino experiment, to measure the proton’s size and structure using a neutrino-scattering technique. For the first time, particle physicists have been able to ...

Acid reducing medicines from the group of proton pump inhibitors (PPIs) are best-selling drugs that prevent and alleviate stomach problems. PPIs are activated in the acid-producing cells of the ...
