Microsoft Researchers Figure Out How to Store Data Inside Glass Using Lasers

The researchers say the data could be retrieved from the glass in 10,000 years.

Most of the world’s information is stored digitally right now. Every year, we generate more data than we did the year before. Now, with AI in the picture, a technology that relies on a whole lot of data, the amount of digital information we save is increasing exponentially.

The research arm of Microsoft has been working on a method for data storage that uses a laser to write inside glass. The researchers say that the information written in the glass will last for 10,000 years.

If this method can be scaled for commercial use, it could change how we store the world’s information. Data rot — losing information due to old storage systems — means we have to transfer data at least once every generation to keep it. Otherwise, it gets corrupted with age.

Microsoft’s Project Silica research director Richard Black tells CNET that its work shows long-term digital storage in glass is practical, not just a science experiment.

«One of the biggest challenges with today’s storage is that media wears out and has to be replaced regularly,» Black says. «Glass doesn’t have that problem.»

Using a laser to modify pieces of glass to keep data safe for many lifetimes could have a drastic and lasting impact on all of the information we decide to keep.

Glass memory

Storing data in glass instead of using traditional digital systems is a project Microsoft has been working on for quite a while. Here’s a video that CNET made of the project six years ago, when it was just an idea.

On Feb. 18, Microsoft’s Project Silica published a paper in the science journal Nature that shows real advances in this long-term project. One of the big advances is writing the information on a less expensive material, which makes this technique more affordable.

Originally, the researchers used glass called fused silica. But this material, which is used for components in lasers and semiconductors, is expensive to manufacture, which could make the storage technology cost-prohibitive for many purposes.

Now, the researchers figured out how to store information in a sturdy glass that’s used for kitchen cookware, called borosilicate glass. This material cuts down the cost significantly.

Writing with lasers

To write in the glass, Project Silica has been using femtosecond lasers. A femtosecond is one quadrillionth of a second. This kind of laser emits super-fast pulses. It’s commonly used for eye surgeries because it can cut underneath without damaging the surface.

To store information, the laser cuts voxels inside the glass. A voxel is like a pixel, but it stores information in three dimensions, like a cube, instead of in two dimensions. The video game Minecraft famously uses voxels to create its worlds.

«The key breakthrough is something the team calls phase voxels: tiny, controlled changes written inside ordinary borosilicate glass using a single laser pulse,» Black says. «This makes writing and reading data simpler and faster, and allows the use of low-cost glass rather than specialized materials.»

Because glass is a hard material, it’s not going to change over time. That’s why this storage method could maintain the integrity of the data for much longer than a standard computer system.

To retrieve the information, Project Silica has devised archives to hold the pieces of glass. Robots retrieve the glass, and then a neural network reads the data that’s written inside. Microsoft has a website that shows the robots zooming across the archive to retrieve the glass.

Perpetual storage

Microsoft has already used this storage technique in proofs of concept. In 2019, Project Silica stored the 1978 Superman film inside a piece of glass the size of a drink coaster.

In Svalbard, Norway, this technology is being used for the Global Music Vault project, which is designed to «future-proof» a wide variety of music. Microsoft also says this technology could complement projects like the Global Seed Vault in Svalbard, a doomsday vault that has a repository of seeds from different plants around the world.

«Glass is extremely durable and can tolerate heat, humidity, electromagnetic interference and physical damage much better than hard drives or magnetic tape,» Black says. «It also lasts far longer, meaning data doesn’t need to be recopied every few years.

«Because it’s naturally resistant to tampering and doesn’t require ongoing power or frequent replacement, it’s especially well suited for archives,» he continues. «Over long time scales, it can also be more sustainable than today’s storage technologies.»

Google races to put Gemini at the center of Android before Apple’s AI reboot

Google is using its latest Android rollout to position Gemini as the AI layer across phones, Chrome, laptops and cars.

Google is using its latest Android rollout to make Gemini less of a chatbot and more of an operating layer across the phone, browser, car and laptop, just weeks before Apple is expected to show its own Gemini-powered Apple Intelligence reboot at WWDC.
Ahead of its Google I/O developer conference next week, the company previewed a number of Android updates, including AI-powered app automation, a smarter version of Chrome on Android, new tools for creators, a redesigned Android Auto experience, and a sweeping set of new security features.
Alphabet is counting on Gemini to help Google compete directly with OpenAI and Anthropic in the market for artificial intelligence models and services, while also serving as the AI backbone across its expansive portfolio of products, including Android. Meanwhile, Gemini is powering part of Apple’s new AI strategy, giving Google a role in the iPhone maker’s reset even as it races to prove its own version of personal AI on the phone is further along.
Sameer Samat, who oversees Google’s Android ecosystem, told CNBC that Google is rebuilding parts of Android around Gemini Intelligence to help users complete everyday tasks more easily.
“We’re transitioning from an operating system to an intelligence system,” he said.
As part of Tuesday’s announcements. Google said Gemini Intelligence will be able to move across apps, understand what’s on the screen and complete tasks that would normally require a user to jump between multiple services. That means Android is moving beyond the traditional assistant model, where users ask a question and get an answer, and acting more like an agent.
For instance, Google says Gemini can pull relevant information from Gmail, build shopping carts and book reservations. Samat gave the example of asking Gemini to look at the guest list for a barbecue, build a menu, add ingredients to an Instacart list and return for approval before checkout.
A big concern surrounding agentic AI involves software taking action on a user’s behalf without permissions. Samat said Gemini will come back to the user before completing a transaction, adding, “the human is always in the loop.”
Four months after announcing its Gemini deal with Google, Apple is under pressure to show a more capable version of Apple Intelligence, which has been a relative laggard on the market. Apple has long framed privacy, hardware integration and control of the user experience as its advantages.
Google’s Android push is designed to show it can bring AI deeper into the device experience while still giving users control over what Gemini can see, where it can act and when it needs confirmation.
The app automation features will roll out in waves, starting with the latest Samsung Galaxy and Google Pixel phones this summer, before expanding across more Android devices, including watches, cars, glasses and laptops later this year.
The company is also redesigning Android Auto around Gemini, turning the car into another major surface for its assistant. Android Auto is in more than 250 million cars, and Google says the new release includes its biggest maps update in a decade and Gemini-powered help with tasks like ordering dinner while driving.
Alphabet’s AI strategy has been embraced by Wall Street, which has pushed the company’s stock price up more than 140% in the past year, compared to Apple’s roughly 40% gain. Investors now want to see how Gemini can become more central to the products people use every day.

Waymo recalls 3,800 robotaxis after glitch allowed some vehicles to ‘drive into standing water’

Waymo issued a voluntary recall of about 3,800 of its robotaxis to fix software issues that could allow them to drive into flooded roadways.

Waymo is recalling about 3,800 robotaxis in the U.S. to fix software issues that could allow them to “drive onto a flooded roadway,” according to a letter on the National Highway Traffic Safety Administration’s website.
The voluntary recall is for Waymo vehicles that use the company’s fifth and sixth generation automated driving systems (or ADS), the U.S. auto safety regulator said in the letter posted Tuesday.
Waymo autonomous vehicles in Austin, Texas, were seen on camera driving onto a flooded street and stalling, requiring other drivers to navigate around them. It’s the latest example of a safety-related issue for the Alphabet-owned AV unit that’s rapidly bolstering its fleet of vehicles and entering new U.S. markets.
Waymo has drawn criticism for its vehicles failing to yield to school buses in Austin, and for the performance of its vehicles during widespread power outages in San Francisco in December, when robotaxis halted in traffic, causing gridlock.
The company said in a statement on Tuesday that it’s “identified an area of improvement regarding untraversable flooded lanes specific to higher-speed roadways,” and opted to file a “voluntary software recall” with the NHTSA.
“Waymo provides over half a million trips every week in some of the most challenging driving environments across the U.S., and safety is our primary priority,” the company said.
Waymo added that it’s working on “additional software safeguards” and has put “mitigations” in place, limiting where its robotaxis operate during extreme weather, so that they avoid “areas where flash flooding might occur” in periods of intense rain.

Qualcomm tumbles 13% as semiconductor stocks retreat from historic AI-fueled surge

Semiconductor equities reversed sharply after a broad AI-driven advance, with Qualcomm suffering its worst day since 2020 amid inflation concerns and rising oil prices.

Semiconductor stocks fell sharply on Tuesday, reversing course after an extensive rally that had expanded the artificial intelligence investment theme well past Nvidia and driven the industry to unprecedented levels.

Qualcomm plunged 13% and was on track for its steepest single-day decline since 2020. Intel shed 8%, while On Semiconductor and Skyworks Solutions each lost more than 6%. The iShares Semiconductor ETF, which benchmarks the overall sector, fell 5%.

The sell-off came after a key gauge of consumer prices came in above forecasts, and as conflict in Iran pushed crude oil higher—prompting investors to shift away from riskier assets.

The preceding advance had widened the AI opportunity set beyond longtime industry leader Nvidia, which for much of the past several years had largely carried the market to new peaks on its own.

Explosive appetite for central processing units, along with the graphics processing units that power large language models, has sent chipmakers to all-time highs.

Market participants are wagering that the shift from AI model training to autonomous agents will lift demand for additional AI hardware. Among the beneficiaries are memory chip producers, which are raising prices as supply remains tight.

Micron Technology slid 6%, and Sandisk cratered 8%. Sandisk’s stock has surged more than six times over since January.
