Finally, those scientists have been working on something actually important.
Forget about your large hadron colliders and what have you, there's been a real scientific breakthrough has been made this week as scientists at a Swiss agricultural institute finally found out what makes holes in Swiss cheese.
The Agroscope institute revealed that "microscopically small hay particles" were responsible for the mysterious holes, and that as a result of refined and more hygienic cheese-making methods, the holes had begun to disappear.
They also performed tests using various amounts of the dust, and found that they were able to regulate the number of holes in the cheese. Mystery solved, and we got through the whole story without making a single cheesy pun.
