What if your entire digital life, including Netflix shows, school documents, family photos, and even a computer operating system, could fit into a single drop of DNA?
That might sound like something from a science fiction movie, but it’s real. And it’s all thanks to a man named Yaniv Erlich, a scientist who blends computer science with biology in surprising ways. People call him the “genome hacker” because he’s known for using DNA in clever, unexpected ways.
A few years ago, Erlich did something that shocked the internet. He and his research partner found a way to store digital files inside synthetic DNA. Not only that, but they also retrieved the data with zero errors, even after copying the DNA many times. This idea quickly went viral in science and tech communities because it felt like a huge leap into the future.
Now, people everywhere are asking: Can DNA really replace hard drives? Could it solve the world’s data storage problem? This article explores how Erlich pulled it off, why it matters, and what it could mean for your digital future.

Meet the Man Behind It: Yaniv Erlich
Yaniv Erlich is a scientist who works with both genetics and computer science. People often call him a “genome hacker” because he finds creative ways to use DNA beyond biology. He was born in Israel and studied brain science and bioinformatics. Over the years, he worked at places like MIT, Columbia University, and MyHeritage. Today, he leads a biotech company called Eleven Therapeutics.
He has done other amazing projects before, like building a 13-million-person family tree and helping identify criminals through DNA matching. But the DNA storage breakthrough may be his most mind-blowing work yet.
What Did He Actually Do?
Together with researcher Dina Zielinski, Yaniv Erlich created a method called DNA Fountain. They used it to store digital data inside lab-made DNA. The files they chose included a short film, a full operating system, scientific papers, and even a $50 Amazon gift card.
Altogether, they stored 2.14 million bytes of data. That may not sound like a lot, but what’s impressive is how small the storage medium was. They managed to fit all of this into a tiny amount of synthetic DNA, no larger than a speck of dust. And the best part? They were able to retrieve it with zero errors.
How Does This Work?
To understand it, think of DNA as a natural USB stick. Just like computers store data as 0s and 1s, DNA stores information using four chemical letters: A, C, G, and T. The scientists wrote a program that turned digital files into those four letters.
Next, they used lab machines to create actual DNA strands based on those letters. Then, they stored the DNA safely. Later, they used a sequencing machine, which is a tool for reading DNA, to turn the data back into usable files.
All of this worked perfectly, even after copying the DNA many times. That shows how stable and reliable this method can be.
Why Is This Such a Big Deal?
Right now, the world creates more digital data every day than ever before. Photos, videos, messages, and websites take up space. Hard drives and cloud storage need electricity and don’t last forever. In fact, most digital storage devices fail after 10 to 20 years.
DNA is different. It can store massive amounts of data in a tiny space and can survive for thousands of years. Erlich’s team achieved a storage density of around 215 petabytes per gram. That is one of the highest densities ever recorded. It’s like putting hundreds of millions of books in a teaspoon.
Also, DNA doesn’t require electricity to stay intact. That makes it more eco-friendly and ideal for long-term storage, especially in places where power is limited.
How Did They Pull It Off?
The secret is a special coding method called DNA Fountain. It’s based on something called “fountain codes,” which are often used in video streaming. This type of code helps prevent data loss and ensures that information can be rebuilt even if some pieces go missing.
Here’s what they did step by step:
- Compressed the digital files into smaller data chunks.
- Turned those chunks into DNA code using Python scripts.
- Synthesized (built) the DNA in a lab.
- Stored the DNA.
- Retrieved the data later using sequencing tools from a company called Illumina.
The code they used is open to the public and available on GitHub at github.com/TeamErlich/dna-fountain. There’s even a video showing how they extracted the operating system KolibriOS from DNA on their website: dnafountain.teamerlich.org.
Why Did This Go Viral?
This story exploded in 2017 when Erlich and Zielinski published their research in the journal Science. Tech blogs, science magazines, and social media users quickly shared the news. Sites like Hacker News and Reddit buzzed with excitement, calling it “sci-fi come true.”
People were amazed that movies and books could live inside molecules. Comments like “This is straight out of Star Trek!” or “Imagine saving human history in DNA” showed how excited the public was.
Even without a single viral tweet or video, the idea caught fire because it felt both futuristic and possible.
Is It Real or Just Hype?
This is very real. The research was peer-reviewed and published in one of the world’s top journals. The team shared all their methods, and others have since built on their work.
Still, there are challenges. It’s expensive, slow, and not ready for everyday use. But it’s a solid first step. Erlich himself said,
“To the best of our knowledge, this is the highest-density storage device ever created.”
What’s Next for Yaniv Erlich?
After this project, Erlich kept exploring DNA in creative ways. In 2020, he worked on “DNA of Things,” where data was hidden inside 3D-printed objects like a plastic bunny. Imagine printing an item that secretly carries a video or instruction manual inside its very material.
Today, he’s focused on biotech and leads Eleven Therapeutics, a company that uses RNA to build new medicines. While his work has shifted from storage to health, the impact of DNA Fountain is still growing.
Final Thoughts
Yaniv Erlich’s DNA Fountain project shows how science and coding can come together to do something amazing. It gives us a peek at a future where your digital life might be saved in the same molecules that carry life itself.
Whether you’re a student, a coder, or just curious, this story proves that geeky ideas can help solve big global problems. Who knows? Maybe one day your phone backup will live inside a drop of DNA.
