“The idea has ____ to make science accessible to everybody,” said Prakash.
While researching methods
____ researching methods for identifying infectious diseases in Thailand in 2011, Prakash came across an expensive microscope that was meant for malaria testing but was unused.
Malaria takes over half a million lives ____ so early diagnosis is crucial in preventing its spread.
But then, why was the ____ sitting unused?

As it was a delicate and expensive instrument, even trained lab ____ felt nervous about using it.
Prakash ____ wondering.
A cheap, strong microscope could ____ thousands of lives.
After he returned to Stanford University,
After he returned to Stanford University, where he was a professor, he started to reflect ____ the idea.
It was not until he met Jim Cybulski that his idea of an affordable and accessible microscope began ____ take shape.
A graduate student at Stanford, ____ was looking for ways to apply his engineering background to make a difference in the real world.
After hearing Prakash’s ____ Cybulski quickly recognized its potential and was eager to contribute.
For a microscope to function properly, it ____ meet certain minimum requirements.
____ include an eyepiece, a tube through which the viewer looks, and a lens for magnification.
The microscope must also have a component that can hold a specimen and move from ____ to side to explore different areas of the specimen.
Furthermore, a mechanism to bring the ____ into focus, usually accomplished by moving it closer to or farther from the lens, is necessary.
Finally, a light source is required to illuminate the ____
An ideal microscope
An ideal microscope would be made with the best performing materials ____ mechanisms for each component.
However, such a ____ would likely be enormously expensive.
On the other hand, a cheap microscope may not be able to deliver high ____
Prakash and Cybulski experimented with various designs and ____ in order to find a suitable compromise.
While many ____ might have settled for a middle ground between these two extremes, Prakash and Cybulski were determined to create a microscope that was both inexpensive and high-performing, while remaining accessible to all.
After drawing various designs on paper, Prakash and Cybulski realized that paper could be ____ excellent medium for their microscope.
It was cheap, easy ____ cut and fold with precision, and widely available.
They faced many challenges during their attempts ____ develop the perfect design.
Ultimately, they settled on waterproof cardboard ____ with a small glass ball lens and named their invention the Foldscope.
The Foldscope provides
The Foldscope provides a magnification of 140 times, making it ____ of examining blood cells, bacteria, and single-celled organisms.
It is ____ portable, weighs just 8 grams, fits easily in a pocket, and requires no external power source.
Moreover, the Foldscope is built to ____ capable of surviving a three-story fall.
Its usefulness is further enhanced by its compatibility with phone cameras, allowing users to take pictures and record images of the ____
It is also possible to project a ____ image on a wall using the phone light.
It is no surprise that over 1.8 million Foldscopes have been ____ in over 160 countries, making it an invaluable tool for scientists worldwide.
The ____ has been utilized for various purposes beyond malaria diagnosis.
In Nigeria, it has also ____ instrumental in detecting fake antimalarial drugs.
The drugs are responsible for over 100,000 deaths annually in sub-Saharan Africa, ____ among children under five.
____ crushed into powder and examined under a Foldscope, real drugs appear as uniform particles, while fake drugs appear as mere powder.
Furthermore, over 400 scientific papers have been published using ____ data, and around 1,200 projects are currently in progress in India.
In the United States, Foldscope programs in public libraries have introduced many children ____ the wonders of science.
If Prakash and Cybulski had given up on their idea of the Foldscope, these achievements could ____ have occurred.
As billions of people lack access to health care and thousands of preventable deaths occur, science is playing a crucial role ____ finding solutions to these challenges.
Tools like the Foldscope, which make science accessible to ____ are becoming increasingly important.
