DNA Gets Artificial Upgrade to Store Humanity’s Boundless Digital Data

Scientists added seven new letters to the existing nucleotide alphabet, opening the door for extreme levels of data storage capacity.

In the last few years, humanity has created more data than in all of history combined — a remarkable level of output with no signs of slowing down. But where are we going to put all of it?

Though scientists are constantly increasing hard drive sizes to hold humanity’s information, and many of them believe this could be done indefinitely, some suggest these efforts will eventually be outrun by the exponential rate at which we generate data. In response to such worries, scientists have been looking into a rather unique solution — storing files, photos and documents on nature’s very own information database: DNA.

DNA is both vast and condensed enough to contain an unfathomable amount of data in hyper small spaces. After all, the double helix strands protect our bodies’ entire blueprints while tucked inside cell nuclei merely 10 micrometers wide. Plus, DNA is naturally abundant and can withstand super harsh conditions on Earth. Scientists can even retrieve genetic information from DNA that’s several centuries old.

«Every day, several petabytes of data are generated on the internet. Only one gram of DNA would be sufficient to store that data. That’s how dense DNA is as a storage medium,» Kasra Tabatabaei, a researcher at the Beckman Institute for Advanced Science and Technology, said in a statement.

Tabatabaei is the co-author of a new study, published in last month’s edition of the journal Nano Letters, that may well take the DNA data storage concept to great heights. Essentially, the study team is the first to artificially extend the DNA alphabet, which could allow for massive storage capacities and accommodate a pretty extreme level of digital data.

Before we dive into the details, here’s a quick biology recap.

DNA encodes genetic information with four molecules called nucleotides. There’s adenine, guanine, cytosine and thymine, or A, G, C and T. In a sense, DNA has a four-letter alphabet, and different letter combinations represent different bits of data. With just these four letters, nature can encode the genetic information of every single living organism. So, theoretically, we should be able to store a ton of digital data with this crew of letters, too. But what if we had a longer alphabet? Presumably, that’d give us a much deeper capacity.

Following this line of thought, the team behind the new study artificially added seven new letters to the DNA repertoire. «Imagine the English alphabet,» Tabatabei said. «If you only had four letters to use, you could only create so many words. If you had the full alphabet, you could produce limitless word combinations. That’s the same with DNA. Instead of converting zeroes and ones to A, G, C and T, we can convert zeroes and ones to A, G, C, T and the seven new letters in the storage alphabet.»

Further, ensuring information encoded in these 11 letters can be regurgitated on demand, the researchers also coined a novel mechanism that precisely reads back the synthetic DNA’s data. The system uses deep-learning algorithms and artificial intelligence to discern between the human-made DNA letters and natural ones, as well as differentiate everything from one another.

All in all, it provides an extremely clear readout of the DNA’s letter combinations, thereby unveiling any and all information hiding inside.

«We tried 77 different combinations of the 11 nucleotides, and our method was able to differentiate each of them perfectly,» Chao Pan, a graduate student at the University of Illinois Urbana-Champaign and a co-author on this study, said in a statement, and «the deep learning framework as part of our method to identify different nucleotides is universal, which enables the generalizability of our approach to many other applications.»

DNA isn’t the only up and coming, innovative way of holding our compounding data. A Harvard University research team, for instance, is working on using neon dyes to encode invaluable information. Still, Tabatabaei remarked, «DNA is nature’s original data storage system. We can use it to store any kind of data: images, video, music — anything.»

Double Dazzle: This Weekend, There Are 2 Meteor Showers in the Night Sky

Lyrids began last week, and Eta Aquariids kicks off on Sunday.

We’ve had good reasons to look up at the skies lately: the pink moon earlier this month and the launch and splashdown of the Orion spacecraft, which carried humans to the moon for the first time in more than 50 years on the Artemis II mission.

And now we have two meteor showers.

The first is the Lyrids, which began on Tuesday and continues until the end of the month. It’s a relatively minor meteor shower fed by the C/1861 G1 comet, also known as Thatcher after its discoverer, A.E. Thatcher, in 1861. It’s a long-period comet that takes 415.5 years to orbit the sun.

The Lyrids meteor shower peaks between April 21 and April 22 and will produce somewhere between 15 and 20 meteors per hour under optimal conditions. Per the American Meteor Society, the peak should occur on the evening of April 22, so if you can only make it out for one of the two nights, the second night is expected to be the better viewing experience.

The second meteor shower starting this weekend is the Eta Aquariids. This meteor shower begins on Sunday, April 19 and spans for over a month, wrapping up on May 28. This is the stronger of the two meteor showers with an expected peak of roughly 50 meteors per hour, depending on where you view them from. The Eta Aquariids shower is known for its fast meteors and persistent tails that stick around for a little longer after the meteor has disappeared.

The 1P/Halley comet feeds it, the same one that feeds the Orionids meteor shower every October. Its peak should be between May 5 and May 6. The further south you are, the more meteors you can expect to see, and the opposite is true the further north you go. The best place to view this meteor shower is in the tropics.

How to see Lyrids and Eta Aquariids

Meteor showers come with a built-in trick for finding them. They are named for the constellations where the meteors appear to originate. This origin point, known as the radiant, is where you want to be looking.

The Lyrids meteor shower originates from the Lyra constellation, which is close to the larger Hercules constellation. Both of them rise from the eastern sky shortly around 11 p.m. local time. It will then follow a similar trajectory to the sun, streaking overhead before setting in the west. Sunrise happens long before the constellations actually set, so if you’re waking up early to view these, you’ll want to look high in the western sky.

The Eta Aquariids shower is more difficult to view. It originates from the Aquarius constellation, which spends most of the night of May 5-6 below the eastern horizon. The constellation rises around 3 a.m. local time and will only barely breach the horizon before sunrise a few hours later. If you go out to view the eta Aquariids, get up high and point yourself east.

If you’re having trouble finding the constellations, your best bet is using a sky map app like StarWalk (Android and iOS) or using web tools like Stellarium’s Sky Map. Such tools can help you identify where the constellations will be. For meteor shower viewing, all you really need is the general direction, but there’s no harm in knowing how to find the constellation.

Tips for viewing meteor showers

The advice for viewing meteor showers is the same, no matter how big or small the shower is. The single biggest advantage you can give yourself is getting as far away from light pollution as you can. This means leaving the city and the suburbs behind in favor of greener, dimmer pastures.

The moon can significantly impact viewing. This won’t be a problem for Lyrids since the moon is expected to be about a quarter full during Lyrids’ peak. Eta Aquariids viewers aren’t so lucky since the moon will be about 80% full that night, which will cause significant light pollution. The American Meteor Society says that the shower’s peak may be up to 50 meteors per hour, but with the moon that close to full, people can expect closer to 10.

Other than light pollution, the advice is pretty simple. Make sure to get out there early so your eyes can adjust, and avoid using any bright lights that could affect your night vision. Since meteor shower watching can be a multihour activity, make sure to dress appropriately for the weather and abstain from alcohol, since it acts as a vasodilator and can cause you to lose body heat more quickly on cold evenings.

You won’t need any equipment since meteors are visible to the naked eye. Telescopes and binoculars will reduce your field of view, which may cause you to miss meteors.

Kevin Weil and Bill Peebles exit OpenAI as company continues to shed ‘side quests’ | TechCrunch

Kevin Weil and Bill Peebles are leaving OpenAI as the company shuts down Sora and folds its science team, signaling a sharp pivot away from consumer moonshots toward enterprise AI.

OpenAI is losing two of the architects of its most ambitious moonshots. Kevin Weil, who led the company’s science research initiative, and Bill Peebles, the researcher behind AI video tool Sora, both announced their departures on Friday. The exits come as OpenAI consolidates around enterprise AI and its forthcoming “superapp.”

The departures follow OpenAI’s decision to cut back on “side quests,” including customer-facing bets like Sora and OpenAI for Science. Sora, which was losing an estimated $1 million per day in compute costs, was shut down last month.

OpenAI for Science was the internal research group behind Prism, an AI-powered platform that promised to accelerate scientific discovery. It’s being absorbed into “other research teams,” according to Weil’s social media post announcing the news.

“It’s been a mind-expanding two years, from Chief Product Officer to joining the research team and starting OpenAI for Science,” Weil wrote. “Accelerating science will be one of the most stunningly positive outcomes of our push to AGI.”

The team had a short and bumpy road after its formal announcement in October 2025. Weil deleted a tweet claiming GPT-5 had solved 10 previously unsolved Erdős mathematical problems, but that claim fell apart immediately when the mathematician who runs the website erdosproblems.com called it out.

Weil’s departure comes a day after his team released GPT-Rosalind, a new model to accelerate life sciences research and drug discovery.

In a social media post announcing his departure, Peebles credited Sora with igniting a “huge amount of investment in video across the industry,” and argued that the kind of research that produced the video tool requires space away from the company’s mainline roadmap.

“Cultivating entropy is the only way for a research lab to thrive long-term,” he wrote.

OpenAI is also losing Srinivas Narayanan, its chief technology officer of enterprise applications, Wired reports. Narayanan reportedly announced the news internally that he was leaving to spend more time with family.

This article was updated to include the departure of Srinivas Narayanan.

Sam Altman’s World Initiative Expands Human Verification to Tinder and Beyond

Sam Altman’s World initiative expands its human verification technology, starting with a global rollout on Tinder and introducing new features like Concert Kit to combat scalpers and deepfakes.

At a popular spot near the San Francisco waterfront, Sam Altman’s verification project World marked its latest phase and ambitious growth. The initiative begins by partnering with Tinder.

Tools for Humanity (TFH), the firm driving the World project, revealed on Friday that it will embed its verification technology into dating platforms, event ticketing networks, corporate entities, email services, and various other sectors of daily life.

«The world is approaching incredibly advanced AI, which is accomplishing remarkable things,» Altman noted while addressing a full room at The Midway. «However, we are moving toward an era where AI-generated content will surpass human-created material,» he continued. «I am certain many of you [have experienced] moments where you question, ‘Am I communicating with an AI or a real person, or what is the ratio, and how can I verify?’»

World (previously known as Worldcoin) sets itself apart from other identity verification services by enabling the confirmation that a genuine, living individual is accessing a digital platform while maintaining their privacy. This relies on sophisticated cryptographic methods (specifically, «zero-knowledge proof-based authentication»). The result: The organization is developing what it terms «proof of human» solutions, which are systems designed to confirm human presence in an environment increasingly populated by AI agents and automated bots.

Its primary verification instrument is a spherical device named the Orb, which captures a user’s eye patterns to generate a distinct, anonymous cryptographic code (referred to as a verified World ID). This code can then be utilized to access World’s services, though individuals may also use the World application without possessing an Orb.

Altman’s speech on Friday was concise (TFH’s co-founder and CEO, Alex Blania, was missing due to unexpected hand surgery, according to Altman). He subsequently passed the presentation to World’s chief product officer, Tiago Sada, and his colleagues.

Sada detailed that World is introducing the latest iteration of its application (the previous release was unveiled during a December gathering), alongside numerous new technology integrations.

World has been working for a while to introduce a verification system for dating applications — particularly Tinder. Last year, Tinder initiated a World ID trial program in Japan. This trial reportedly succeeded, prompting World to announce that Tinder would roll out its verification integration across global markets, including the U.S. The system adds a World ID badge to the profiles of users who complete its verification steps, confirming their authenticity as real individuals.

World is also targeting the entertainment sector with a new feature called Concert Kit, allowing musicians to set aside specific ticket quantities for World ID-verified attendees. This aims to protect fans from scalpers who frequently employ automated ticket-purchasing bots to secure seats. Concert Kit works with major ticketing platforms like Ticketmaster and Eventbrite, and the company is highlighting it through collaborations with 30 Seconds to Mars and Bruno Mars — both of whom intend to utilize it for their upcoming tours.

The gathering featured numerous additional announcements, including those focused on corporate clients. A Zoom/World ID verification integration aims to counter a perceived deepfake risk in business calls, and a Docusign partnership is designed to ensure
