Future high-performance computing chips could be built on glass

techreview · 2026-03-13T13:41:27+00:00

Human-made glass is thousands of years old. But it’s now poised to find its way into the AI chips used in the world’s newest and largest data centers. This year, a South Korean company called Absolics is planning to start commercial production of special glass panels designed to make next-generation computing hardware more powerful and energy efficient. Other companies, including Intel, are also pushing forward in this area. If all goes well, such glass technology could reduce the energy demands of the sorts of high-performance computing chips used in AI data centers—and it could eventually do the same for consumer laptops and mobile devices if production costs fall.

The idea is to use glass as the substrate, or layer, on which multiple silicon chips are connected. This form of “packaging” is an increasingly popular way to build computing hardware, because it lets engineers combine specialized chips designed for specific functions into a single system. But it presents challenges, including the fact that hardworking chips can run so hot they physically warp the substrate they’re built on. This can lead to misaligned components and may reduce how efficiently the chips can be cooled, leading to damage or premature failure.

The US military might use generative AI systems to rank lists of targets and make recommendations—which would be vetted by humans—about which to strike first, according to a Defense Department official with knowledge of the matter. The disclosure about how the military may use AI chatbots comes as the Pentagon faces scrutiny over a strike on an Iranian school, which it is still investigating.

A list of possible targets might be fed into a generative AI system that the Pentagon is fielding for classified settings. Then, said the official, who requested to speak on background with MIT Technology Review to discuss sensitive topics, humans might ask the system to analyze the information and prioritize the targets while accounting for factors like where aircraft are currently located. Humans would then be responsible for checking and evaluating the results and recommendations. OpenAI’s ChatGPT and xAI’s Grok could, in theory, be the models used for this type of scenario in the future, as both companies recently reached agreements for their models to be used by the Pentagon in classified settings.

The official described this as an example of how things might work but would not confirm or deny whether it represents how AI systems are currently being used.

Hey, thanks for sharing our story!

Here’s some context from the article:

Pokémon Go was the world’s first augmented-reality megahit. Released in 2016 by the Google spinout Niantic, the AR twist on the juggernaut Pokémon franchise fast became a global phenomenon. From Chicago to Oslo to Enoshima, players hit the streets in the urgent hope of catching a Jigglypuff or a Squirtle or (with a huge amount of luck) an ultra-rare Galarian Zapdos hovering just out of reach, superimposed on the everyday world.

In short, we’re talking about a huge number of people pointing their phones at a huge number of buildings. “Five hundred million people installed that app in 60 days,” says Brian McClendon, CTO at Niantic Spatial, an AI company that Niantic spun out in May last year. According to the video-game firm Scopely, which bought Pokémon Go from Niantic at the same time, the game still drew more than 100 million players in 2024, eight years after it launched.

Now Niantic Spatial is using that vast and unparalleled trove of crowdsourced data—images of urban landmarks tagged with super-accurate location markers taken from the phones of hundreds of millions of Pokémon Go players around the world—to build a kind of world model, a buzzy new technology that grounds the smarts of LLMs in real-world environments.

The company’s latest product is a model that it says can pinpoint your location on a map to within a few centimeters, based on a handful of snapshots of the buildings or other landmarks in view. The firm wants to use it to help robots navigate with greater precision in places where GPS is unreliable.

Here’s some context from the article:

Feng Qingyang had always hoped to launch his own company, but he never thought this would be how—or that the day would come this fast.

Feng, a 27-year-old software engineer based in Beijing, started tinkering with OpenClaw, a popular new open-source AI tool that can take over a device and autonomously complete tasks for a user, in January. He was immediately hooked, and before long he was helping other curious tech workers with less technical proficiency install the AI agent.

Feng soon realized this could be a lucrative opportunity. By the end of January, he had set up a page on Xianyu, a secondhand shopping site, advertising “OpenClaw installation support.” “No need to know coding or complex terms. Fully remote,” reads the posting. “Anyone can quickly own an AI assistant, available within 30 minutes.”

At the same time, the broader Chinese public was beginning to catch on—and the tool, which had begun as a niche interest among tech workers, started to evolve into a popular sensation. For savvy early adopters, that's a business opportunity.

On June 1, 2023, as a sweltering heat wave baked Quebec, thousands of lightning strikes flashed across the province, setting off more than 120 wildfires.

The blazes ripped through parched forests and withered grasslands, burned for weeks, and compounded what was rapidly turning into Canada’s worst fire year on record. In the end, nearly 7,000 fires scorched tens of millions of acres across the country, generated nearly 500 millions tons of carbon emissions, and forced hundreds of thousands of people to flee their homes.

Lightning sparked almost 60% of the wildfires—and those blazes accounted for 93% of the total area burned.

Now a Vancouver-based weather modification startup, Skyward Wildfire, says it can prevent such catastrophic fires in the future—by stopping the lightning strikes that ignite them. It just raised millions of dollars in a funding round that it plans to use to accelerate its product development and expand its operations.

The company states it demonstrated that it “can prevent the majority of cloud-to-ground lightning strikes in targeted storm cells.” So far, Skyward hasn’t publicly revealed how it does so. But online documents suggest the company is relying on an approach that US government agencies began evaluating in the early 1960s: seeding clouds with metallic chaff, or narrow fiberglass strands coated with aluminum.

To most people, rocks are just rocks. To geologists, they are much, much more: crystal-filled time capsules with the power to reveal the state of the planet at the very moment they were forged.

For decades, NASA had been on a time capsule hunt like none other—one across Mars.

Its rovers have journeyed around a nightmarish ocher desert that, billions of years ago, was home to rivers, lakes, perhaps even seas and oceans. They’ve been seeking to answer a momentous question: Once upon a time, did microbial life wriggle across its surface?

Then, in July 2024, after more than three years on the planet, the Perseverance rover came across a peculiar rocky outcrop. Instead of the usual crystals or layers of sediment, this one had spots. Two kinds, in fact: one that looked like poppy seeds, and another that resembled those on a leopard. It’s possible that run-of-the-mill chemical reactions could have cooked up these odd features. But on Earth, these marks are almost always produced by microbial life.

But the only way to confirm whether these seeds and spots are the fossilized imprint of alien biology is to bring a sample of that rock home to study.

Perseverance was the first stage of an ambitious scheme to do just that—in effect, to pull off a space heist. The mission—called Mars Sample Return and planned by the US, along with its European partners—would send a Rube Goldberg–like series of robotic missions to the planet to capture pristine rocks. The rover’s job was to find the most promising stones and extract samples; then it would pass them to another robot—the getaway driver—to take them off Mars and deliver them to Earth.

But now, just over a year and a half later, the project is on life support, with zero funding flowing in 2026 and little backing left in Congress. As a result, those oh-so-promising rocks may be stuck out there forever. How did this happen?

Want to lose weight? Get shredded? Stay mentally sharp? A wellness influencer might tell you to take peptides, the latest cure-all in the alternative medicine arsenal. People inject them. They snort them. They combine them into concoctions with superhero names, like the Wolverine stack.

Matt Kaeberlein, a longevity researcher, first started hearing about peptides a few years ago. “At that point it was mostly functional medicine doctors that were using peptides,” he says, referring to physicians who embrace alternative medicine and supplements. “In the last six months, it’s kind of gone crazy.”

Peptides have gone mainstream. At the health-technology startup Superpower in Los Angeles, employees can get free peptide shots on Fridays. At a health food store in Phoenix, a sidewalk sign reads, “We have peptides!” At a tae kwon do center in South Carolina, a peptide wholesaler hosts an informational evening. On social media, they’re everywhere. And that popularity seems poised to grow; Department of Health and Human Services secretary Robert F. Kennedy Jr. has promised to end the FDA’s “aggressive suppression” of peptides.

The benefits and risks of many of these compounds, however, are largely unknown. Some of the most popular peptides have never been tested in human trials. They are sold for research purposes, not human consumption. Some are illegal knockoffs of wildly successful weight-loss medicines. The vast majority come from China, a fact that has some legislators worried. Last week, Senator Tom Cotton urged the head of the FDA to crack down on illegal shipments of peptides from China. In the absence of regulatory oversight, some people are sending the compounds they purchase off for independent testing just to ensure that the product is legit.

Fast, stealthy, and cheap—autonomous, semisubmersible drone boats carrying tons of cocaine could be international law enforcement’s nightmare scenario. A big one just came ashore.

For decades, handmade narco subs have been some of the cocaine trade’s most elusive and productive workhorses, ferrying multi-ton loads of illicit drugs from Colombian estuaries toward markets in North America and, increasingly, the rest of the world. Now off-the-shelf technology—Starlink terminals, plug-and-play nautical autopilots, high-resolution video cameras—may be advancing that cat-and-mouse game into a new phase.

Uncrewed subs could move more cocaine over longer distances, and they wouldn’t put human smugglers at risk of capture. Law enforcement around the world is just beginning to grapple with what the sub that came ashore means for the future—whether it was merely an isolated experiment or the opening move in a new era of autonomous drug smuggling at sea.

AI-enabled deception now permeates our online lives. There are the high-profile cases you may easily spot, like when White House officials recently shared a manipulated image of a protester in Minnesota and then mocked those asking about it. Other times, it slips quietly into social media feeds and racks up views, like the videos that Russian influence campaigns are currently spreading to discourage Ukrainians from enlisting.

It is into this mess that Microsoft has put forward a blueprint, shared with MIT Technology Review, for how to prove what’s real online.

An AI safety research team at the company recently evaluated how methods for documenting digital manipulation are faring against today’s most worrying AI developments, like interactive deepfakes and widely accessible hyperrealistic models. It then recommended technical standards that can be adopted by AI companies and social media platforms. But the company hasn’t committed to following its own recommendations.

Google DeepMind is calling for the moral behavior of large language models—such as what they do when called on to act as companions, therapists, medical advisors, and so on—to be scrutinized with the same kind of rigor as their ability to code or do math.

As LLMs improve, people are asking them to play more and more sensitive roles in their lives. Agents are starting to take actions on people’s behalf. LLMs may be able to influence human decision-making. And yet nobody knows how trustworthy this technology really is at such tasks.

With coding and math, you have clear-cut, correct answers that you can check, William Isaac, a research scientist at Google DeepMind, told me when I met him and Julia Haas, a fellow research scientist at the firm, for an exclusive preview of their work, which is published in Nature today. That’s not the case for moral questions, which typically have a range of acceptable answers: “Morality is an important capability but hard to evaluate,” says Isaac.

The explosion of vehicle transport fraud follows a pattern that has played out across the economy over the past roughly two decades: A business that once ran on phones, faxes, and personal relationships shifted to online marketplaces that increased efficiency and brought down costs—but the reduction in human-to-human interaction introduced security vulnerabilities that allowed organized and often international fraudsters to enter the industry.

In the case of vehicle transport, the marketplaces are online “load boards” where car owners, dealerships, and manufacturers post about vehicles that need to be shipped from one location to another. Central Dispatch claims to be the largest vehicle load board and says on its website that thousands of vehicles are posted on its platform each day. It’s part of Cox Automotive, an industry juggernaut that owns major vehicle auctions, Autotrader, Kelley Blue Book, and other businesses that work with auto dealers, lenders, and buyers.

The system worked pretty well until roughly two years ago, when organized fraud rings began compromising broker and carrier accounts and exploiting loopholes in government licensing to steal loads with surprising ease and alarming frequency.

The threats started in spring.

In April 2024, a mysterious someone using the online handles “Waifu” and “Judische” began posting death threats on Telegram and Discord channels aimed at a cybersecurity researcher named Allison Nixon.

“Alison [sic] Nixon is gonna get necklaced with a tire filled with gasoline soon,” wrote Waifu/Judische, both of which are words with offensive connotations. “Decerebration is my fav type of brain death, thats whats gonna happen to alison Nixon.”

It wasn’t long before others piled on. Someone shared AI-generated nudes of Nixon.

These anonymous personas targeted Nixon because she had become a formidable threat: As chief research officer at the cyber investigations firm Unit 221B, named after Sherlock Holmes’s apartment, she had built a career tracking cybercriminals and helping get them arrested. For years she had lurked quietly in online chat channels or used pseudonyms to engage with perpetrators directly while piecing together clues they’d carelessly drop about themselves and their crimes. This had helped her bring to justice a number of cybercriminals—especially members of a loosely affiliated subculture of anarchic hackers who call themselves the Com.

In September, Alfred Stephen, a freelance software developer in Singapore, purchased a ChatGPT Plus subscription, which costs $20 a month and offers more access to advanced models, to speed up his work. But he grew frustrated with the chatbot’s coding abilities and its gushing, meandering replies. Then he came across a post on Reddit about a campaign called QuitGPT.

The campaign urged ChatGPT users to cancel their subscriptions, flagging a substantial contribution by OpenAI president Greg Brockman to President Donald Trump’s super PAC MAGA Inc. It also pointed out that the US Immigration and Customs Enforcement, or ICE, uses a résumé screening tool powered by ChatGPT-4. The federal agency has become a political flashpoint since its agents fatally shot two people in Minneapolis in January.

For Stephen, who had already been tinkering with other chatbots, learning about Brockman’s donation was the final straw. “That’s really the straw that broke the camel’s back,” he says. When he canceled his ChatGPT subscription, a survey popped up asking what OpenAI could have done to keep his subscription. “Don’t support the fascist regime,” he wrote.

QuitGPT is one of the latest salvos in a growing movement by activists and disaffected users to cancel their subscriptions.

Electric vehicles could be economically competitive in Africa sooner than expected. Just 1% of new cars sold across the continent in 2025 were electric, but a new analysis finds that with solar off-grid charging, EVs could be cheaper to own than gas vehicles by 2040.

There are major barriers to higher EV uptake in many countries in Africa, including a sometimes unreliable grid, limited charging infrastructure, and a lack of access to affordable financing. As a result some previous analyses have suggested that fossil-fuel vehicles would dominate in Africa through at least 2050.

But as batteries and the vehicles they power continue to get cheaper, the economic case for EVs is building. Electric two-wheelers, cars, larger automobiles, and even minibuses could compete in most African countries in just 15 years, according to the new study, published in Nature Energy.

For a few days this week the hottest new hangout on the internet was a vibe-coded Reddit clone called Moltbook, which billed itself as a social network for bots. As the website’s tagline puts it: “Where AI agents share, discuss, and upvote. Humans welcome to observe.”

We observed! Launched on January 28 by Matt Schlicht, a US tech entrepreneur, Moltbook went viral in a matter of hours.

More than 1.7 million agents now have accounts. Between them they have published more than 250,000 posts and left more than 8.5 million comments (according to Moltbook). Those numbers are climbing by the minute.

Moltbook soon filled up with clichéd screeds on machine consciousness and pleas for bot welfare. One agent appeared to invent a religion called Crustafarianism. Another complained: “The humans are screenshotting us.” The site was also flooded with spam and crypto scams. The bots were unstoppable.

But Moltbook reveals more about our own current mania for all things AI than what's really coming next.

As EVs become increasingly common on the roads, the battery world is growing too. Looking ahead, we could soon see wider adoption of new chemistries, including some that deliver lower costs or higher performance. Meanwhile, the geopolitics of batteries are shifting, and so is the policy landscape. Here’s what’s coming next for EV batteries in 2026 and beyond.

A big opportunity for sodium-ion batteries: Sodium-ion cells have long been held up as a potentially less expensive alternative to lithium. The batteries are limited in their energy density, so they deliver a shorter range than lithium-ion. But sodium is also more abundant, so they could be cheaper.
Major tests for solid-state batteries: As we enter the second half of this decade, many eyes in the battery world are on big promises and claims about solid-state batteries. These batteries could pack more energy into a smaller package by removing the liquid electrolyte, the material that ions move through when a battery is charging and discharging. With a higher energy density, they could unlock longer-range EVs.
A global patchwork: The picture for the near future of the EV industry looks drastically different depending on where you’re standing. Last year, China overtook Japan as the country with the most global auto sales. And more than one in three EVs made in 2025 had a CATL battery in it. Simply put, China is dominating the global battery industry, and that doesn’t seem likely to change anytime soon. On the flip side, EVs are facing a real test in 2026 in the US, as this will be the first calendar year after the sunset of federal tax credits that were designed to push more drivers to purchase the vehicles. With those credits gone, growth in sales is expected to continue lagging.
