“A global helium shortage is affecting all sorts of consumers, ranging from the National Weather Service, to party-supply stores, to physicists at universities around the world.

Harvard’s own supply of helium is now reduced to only 50 percent of its usual amount, according to Dean of Science Christopher W. Stubbs.

‘That has forced our experimental groups to greatly curtail the experiments that rely on that as a cryogenic liquid,” Stubbs said. “It impacts both elements of Harvard’s mission, both the research teaching and training element, as well as the research element.’”
