Did you know there's a bank in Italy (Credito Emiliano) that accepts wheels of Parmigiano-Reggiano cheese as collateral for business loans?

They have a massive, high-security climate-controlled warehouse where they store and age hundreds of thousands of cheese wheels (worth hundreds of millions of dollars) while the farmers pay off their debts. Literally a bank vault filled with cheese.

Did you know that humans can smell petrichor, the earthy scent of rain on dry soil, even better than a shark can smell blood in the water?

We're crazy sensitive to a compound called geosmin, which is released by soil bacteria when it rains. We can detect it at just five parts per trillion.
