    Houses of Death 

    Today, we think of the hospital as an exemplar of sanitation. However, during the first half of the nineteenth century, hospitals were anything but hygienic. They were breeding grounds for infection and provided only the most primitive facilities for the sick and dying, many of whom were housed on wards with little ventilation or access to clean water. As a result of this squalor, hospitals became known as “Houses of Death.”

    A 50-cent paper microscope 

    Manu Prakash, a professor at Stanford University and his students have developed a microscope out of a flat sheet of paper, a watch battery, LED, and optical units that when folded together, much like origami, creates a functional instrument with the resolution of 800 nanometers – basically magnifying an object up to 2,000 times.

    Called Foldscope, the microscope is extremely inexpensive to manufacture, costing between fifty-cents and a dollar per instrument. And because the microscope is assembled primarily from paper and optical components the size of a grain of sand, it is virtually indestructible.

    Foldscope also differs from the microscopes typically found in science labs because it’s not only portable, but it also has the ability to project an image on any surface, allowing a larger group of people the ability to look at an image simultaneously.

    Prakash is hoping that because the Foldscope is so cheap to manufacture and easy to assemble that everyone will have access to the world of microscopy and one day every kid will have a Foldscope in their backpacks or tucked away in their pocket.
