It’s the most cancer-causing pathogen we’ve found—and the main cause of peptic ulcers. Its discovery overturned an ironclad medical dogma that the stomach was sterile.

The 2010s witnessed Australia’s weakest productivity growth in six decades. How much of the slowdown is homegrown? How much reflects the broader “great stagnation” plaguing the West?
