  • This rabbit contains the instructions for how to replicate itself, just like all our

  • living cells do.

  • Even though it’s very clearly not alive, its instructions are encoded into DNA and

  • then embedded into this 3D-printed plastic object.

  • Thisis an advanced proof of concept for DNA as data storage.

  • Think about it: just like ones and zeros are the way that computers encode information,

  • DNA base pairs do the same.

  • But DNA offers more density.

  • It obviously packs so much datalike, all of the instructions for a human bodyinto

  • the nucleus of a cell.

  • And teams around the world have been demonstrating that theyre able to encode hundreds of

  • thousands of terabytes of digital data in gram-quantities of DNA.

  • Like can you picture a one-terabyte hard drive?

  • Yeah, now picture hundreds of thousands of those, and all of the information you could

  • store on themvideos, photos, the whole shebangin just a few grams of biological

  • material.

  • So DNA offers quite an improvement on existing digital data storage methods, like the chips,

  • spinning discs, and magnetic tape that were used to.

  • And this rabbit is a first foray into what these researchers are callingthe DNA of

  • things’.

  • So how exactly do you get DNA into a plastic object like this?

  • The scientists stored the instructions for how to 3D print the plastic bunny in chunks

  • of DNA.

  • And then they enclosed that DNA in microscopic glass beads, which protects the DNA from the

  • heat of the 3D-printing process.

  • Then the beads were embedded into liquid plastic, and that mixture was used to 3D print the bunny.

  • When it’s done, you could take a tiny piece of that rabbitlike, milligram quantitiesand run

  • it through a sequencer, decode the information stored in the DNA, and voila: you now have

  • the instructions to make another bunny.

  • And that’s just what the researchers did!

  • They repeated that process, creating five generations of bunnies, if you will.

  • And the team also showed that DNA from a bunny that was stored for nine months showed no

  • significant degradation of the data and could still be used to make another bunny!

  • The plastic rabbit is a cute and relatively simple example of a concept that is pretty mind-bending.

  • This same visionary team did this with a pair of glasses, too.

  • Using the same process, they stored the file for a short movie in the lenses of a pair

  • of perfectly ordinary glasses.

  • That is some Bond-level stuff right there.

  • And in addition to this tech having potential in espionage, it also has a whole host of

  • applications in medicine.

  • Medications, or personal health items like dental implants, could come equipped with

  • information about their safety, uses, and even about the person who needs them.

  • Like you could have the entirety of your medical records stored in your new fake tooth!

  • In DNA!?

  • This is all, of course, only possible if you have the right DNA purification equipment,

  • a portable DNA sequencer, tens of hours, and then of course, the program that decodes the

  • DNA into the digital information.

  • Y’know, just little stuff.

  • But teams all over the world are innovating to bring down the cost and complexity of this

  • tech, and to make it accessible for use in all kinds of industries, like construction, pharmaceuticals,

  • and electronics!

  • It’s really just the start of innovation in the exciting field of DNA data storage.

  • Because we are producing, consuming, and storing more data than ever before in human history.

  • As we advance our computing, and as expanding population gains access to the internet and

  • personal computers, that data volume isn’t going down any time soon.

  • Were going to need better ways to store it and to get it to each other.

  • And it looks like co-opting nature’s best existing data storage strategy just may be

  • part of the solution.

  • Maybe mother nature really does know best.

  • If you haven’t seen our new show, Human, you should definitely check it out.

  • Not only because it’s great, but because we're Human, and we have a bunch of different mechanisms

  • that work together to keep our bodies functioning, and this show talks all about them.

  • If there’s a topic in particular you’d want us to cover, let us know down in the

  • comments, make sure to subscribe and thanks for watching.
