Frugal Science: Enabling Communities with Accessible Tools

Let me take you on a journey that spans over three decades, back to my childhood. As a young and curious mind, I found immense joy in crafting tools and sharing them with others. One of my earliest creations was a makeshift microscope, constructed by repurposing lenses from my brother’s eyeglasses. Although he wasn’t thrilled about it at the time, that small act of ingenuity planted a seed in me that still thrives today: the passion for making microscopes.

Fast forward to the present, and the purpose behind my tool-building endeavors becomes clear. Recently, I came across a heartwarming video that captured a powerful moment. A young girl approached me with a concern about black things in her hair. It was in that classroom in the Bay Area that I realized how the living world surpasses our wildest imagination. Inspired by this encounter, I embarked on a mission.

In my laboratory, we embarked on an ambitious project. Over the past two years, we’ve managed to create an astounding 50,000 Foldscopes, microscopic tools that we have distributed to 130 countries worldwide. What’s even more remarkable is that we provided these microscopes to children at no cost. And this year, with the support of our incredible community, we aim to ship one million microscopes to children across the globe.

Why is this so significant? Well, it’s because of the extraordinary community that forms around these tools. From Kenya to Kampala, Kathmandu to Kansas, we have witnessed people from different corners of the world come together, learning from and teaching one another. It’s truly awe-inspiring.

Allow me to share a few remarkable stories that show the power of this community. In Nicaragua, there is a young child who has taken it upon themselves to educate others about identifying mosquito species that carry dengue, all by observing the larvae under a microscope. In another instance, a dedicated pharmacologist developed a groundbreaking method for detecting counterfeit drugs. Meanwhile, a curious girl delved into the physics behind the captivating phenomenon of glitter’s crystalline formation. And in Argentina, a doctor is striving to conduct cervical cancer screenings using our tools, even in remote areas with limited resources.

Now, you may think of these stories as mere anomalies, but there’s a method to this madness. I call it “frugal science” - a concept centered around sharing the experience of science, not just the information. It’s crucial to remember that billions of people on our planet live without proper infrastructure, devoid of roads, electricity, and even basic healthcare. And among them, a billion children live in poverty. How can we inspire them to become the next generation of problem solvers?

Furthermore, countless healthcare workers put their lives on the line to combat infectious diseases with minimal tools and resources. As a lab based at Stanford University, we believe in the power of frugal science to create solutions for these marginalized communities. We envision the ability to carry out diagnoses under a tree, off the grid.

Let me introduce you to two remarkable tools we’ve developed. Our journey begins in Uganda, where in 2013, during a field trip focused on detecting schistosomiasis with Foldscopes, I made a crucial observation. In a remote clinic with no access to electricity, I spotted a discarded centrifuge being used as a mere doorstop. Centrifuges are vital for sample processing, separating components of blood and body fluids to identify pathogens. However, they are bulky, expensive, and utterly impractical for use in the field without a power source.

This realization sparked a unique line of thinking, and I found myself drawn to the world of toys. I experimented with yo-yos, spinning tops, and eventually stumbled upon a true wonder - the whirligig. This seemingly simple object, comprising a disk, a couple of strings, and a handle, proved to be the key to unlocking a groundbreaking solution: the Paperfuge.

Through mathematical calculations and rigorous experimentation, my team and I developed the complete analytical solution for this dynamic system. The Paperfuge, with its ability to spin at astonishing speeds, has the potential to replace traditional centrifuges that cost thousands of dollars. To put it into perspective, we achieved a mind-boggling speed of 120,000 rpm, equivalent to 30,000 g-forces. It’s a tool that opens up a world of possibilities.

Allow me to demonstrate the Paperfuge’s capabilities. With a simple finger prick and a drop of blood, we can embark on a journey of diagnosis. By separating blood cells from plasma, we can glean valuable insights into an individual’s health. This cost-effective tool not only aids in the detection of diseases like malaria but also allows for the separation of nucleic acids, enabling field-based tests and even multiplex testing. The possibilities are truly endless.

However, the true essence of our work lies in sharing these tools with the world. I recently returned from Madagascar, where we conducted clinical trials for malaria. It was an incredible experience, both humbling and exhilarating, to witness the impact our tools have on communities. The smile on a person’s face when they realize that they now have access to simple yet powerful tools is priceless.

What’s even more astounding is the fact that all of this comes at a remarkably low cost. In fact, it only takes 20 cents to produce one of these life-changing tools. It’s a testament to the power of frugal science and the belief that we can make a difference, one accessible tool at a time.

Before I conclude, there’s one more innovation I must share: Abuzz. Imagine a world where all of us can contribute to the fight against mosquitoes, those pesky carriers of malaria, Zika, chikungunya, and dengue. The challenge lies in not knowing where these enemies reside. However, we discovered their Achilles’ heel - their wingbeat frequencies.

Using a simple flip phone, reminiscent of those we used years ago, we can now record the acoustic signatures of mosquitoes. By tapping them gently and capturing their unique sounds, we can map different species of mosquitoes. This invaluable data, combined with machine learning, allows us to identify and track these disease-carrying insects. It’s a groundbreaking approach, and we invite all of you to join us in our mission.

As I bring this journey to a close, I implore you to reflect on the challenges we face today - healthcare disparities, climate change, biodiversity loss - the list goes on. Science is undoubtedly a crucial tool in addressing these issues, but we must ensure that it is accessible to all, not just those who can afford it. Let’s make scientific literacy a human right.

In the spirit of giving power, I encourage each and every one of you to pass on the joy of discovery to the next generation. By doing so, we enable them to become the problem solvers, innovators, and change-makers of tomorrow. Together, let’s build a future where science knows no boundaries.
