Microscopic World (3x14)

:

This week we look at our microscopic world. Philippe heads to the University of Texas to break down the microscopic world of sand. He'll stay on campus to then look at how microscopic science plays a role in researching fire ants. Then it's off to the University of Pennsylvania to get deeper look into soil. And finally researchers at USC study some of the smallest organisms in the ocean.
