Ceramic material pair could unlock potential of safer, longer-lasting solid-state batteries
A team of four universities and three national laboratories, led by The University of Texas at Austin, developed a new approach for solid-state batteries, improving their performance while reducing the manufacturing costs. Solid-state batteries are an emerging energy storage technology that could unlock enhanced performance for drones, electronics and electric vehicles.
“The biggest game in town for next-generation batteries is making them all solid-state, allowing for improved safety and higher energy,” said David Mitlin, professor in the Cockrell School of Engineering’s Walker Department of Mechanical Engineering and the lead investigator on the new research published in Nature Materials. “However, much more work is needed before all solid-state batteries may be widely commercialized.”
Today, most lithium-ion batteries use an organic liquid electrolyte, a maple-syrup-like substance that allows lithium ions to reversibly shuttle back and forth inside the battery. Despite being technologically mature, liquid electrolytes are the hydrocarbon “fuel” in the oft-reported battery fires.
Solid, ceramic-based electrolytes reduce fire risks, eliminating the hydrocarbon fuel that sustains battery thermal runaway reactions. However, ceramic electrolytes face their own hurdles, including high costs, challenging quality control during manufacturing and premature failure due to metal filament (termed dendrite)–induced short-circuiting.
Oxide ceramics based on the garnet structure are key materials for all solid-state batteries. Garnet’s unique structure allows lithium ions to move quickly and efficiently, making it ideal for energy storage. But even garnet has struggled to overcome the dendrite problem, which is directly linked to the formation of small cracks inside the electrolyte.
Like a jeweler refining a gemstone, the researchers have polished the garnet to reveal its full potential. Dispersing micro-scale zirconia particles throughout the garnet grains suppresses both the cracking and the dendrites.
This method is based on carbide additives, which exothermically decompose during fabrication, inputting additional heat into the synthesis reaction. This creates an additional benefit of reducing the manufacturing cost by lowering the external temperature needed for processing.
“Zirconia really pulls double duty here,” said Yixian Wang, postdoctoral researcher in Mitlin’s lab, who is the co-lead author. “It helps densify the material while also preventing those pesky lithium dendrites from forming. It’s a win–win for battery performance and safety.”
In tests, the zirconia-modified garnet achieved nearly double the critical current density—the maximum current it can handle before short-circuiting—compared to unmodified garnet. This means batteries using this material can operate at higher power levels without compromising safety.
While battery science is the driving force of this research, the results may be applied to a wide variety of manufacturing sectors for high-quality ceramics, where defect control is essential.

New York Is the Latest State to Consider a Data Center Pause
Lawmakers in at least five other states—Georgia, Maryland, Oklahoma, Vermont, and Virginia—have also introduced bills this year that would impose various forms of temporary pauses on data center development. While Georgia, Vermont, and Virginia’s efforts are being led by Democrats, Oklahoma and Maryland’s bills were largely sponsored by Republicans. These bills mirror several moratoriums that have already passed locally: At the end of December, at least 14 states had towns or counties that have paused data center permitting and construction, Tech Policy Press reported.
There are some signs that the data center industry is beginning to respond to the backlash. Last month, Microsoft, with a boost from the White House, rolled out a set of commitments to be a “good neighbor” in communities where it builds data centers. In response to questions on how the industry is responding to the slew of state-level legislation, Dan Diorio, the vice president of state policy at the Data Center Coalition, an industry group, tells WIRED in a statement that it “recognizes the importance of continued efforts to better educate and inform the public about the industry, through community engagement and stakeholder education, which includes factual information about the industry’s responsible usage of water and our commitment to paying for the energy we use.”
Some of the states with moratorium bills have relatively few data centers: Vermont has just two, according to Data Center Map. But Georgia and Virginia are two of the national hubs for data center development and have found themselves at the center of much of the resistance, in both public reaction to data centers and legislative pushback. More than 60 data center-related bills have already been proposed in the Virginia legislature this year, according to Data Center Dynamics, an industry news site.
Josh Thomas is a state delegate in Virginia who has been at the forefront of leading the legislative charge to put limits on the expansion of data centers. During his first legislative session, in 2024, the caucus of self-identified data center “reformers” in both the House and Senate was just three politicians. That number grew to eight in 2025, “and now, it’s 12 or 13,” he says, with many more politicians willing to vote on reform bills. His fellow lawmakers, he says, now “understand that we need to negotiate where these things go.”
Last year, a proposal introduced by Thomas which would have required data centers to perform more in-depth environmental, noise, and community impact site assessments passed the legislature, but was vetoed by then-governor Glenn Youngkin. Newly-elected Governor Abigail Spanberger, a Democrat who talked about making data centers “pay their own way” on the campaign trail, seems much more likely to reconsider this year’s version of the bill, which has already passed the House.
“I’m much more optimistic that [Spanberger] will sign,” Thomas says.
Thomas, who was not involved in shaping the moratorium in the Virginia house, thinks that a moratorium on data centers is much more likely to pass in states where the industry has less of a foothold than Virginia. Still, he says, “it’s not a bad idea.”

More Than 800 Google Workers Urge Company to Cancel Any Contracts With ICE and CBP
More Than 800 employees and contractors working for Google signed a petition this week calling on the company to disclose and cancel any contracts it may have with US immigration authorities. In a statement, the workers said they are “vehemently opposed” to Google’s dealings with the Department of Homeland Security, which includes Immigration and Customs Enforcement (ICE) and Customs and Border Protection (CBP).
“We consider it our leadership’s ethical and policy-bound responsibility to disclose all contracts and collaboration with CBP and ICE, and to divest from these partnerships,” the petition published on Friday states. Google didn’t immediately respond to a request for comment.
US immigration authorities have been under intense public scrutiny this year as the Trump administration ramped up its mass deportation campaign, sparking nationwide protests. In Minneapolis, confrontations between protesters and federal agents culminated in the fatal shooting of two US citizens by immigration officers. Both incidents were captured in widely disseminated videos and became a focal point of the backlash. In the wake of the uproar, the Trump administration and Congress say they are negotiating changes to ICE’s tactics.
Some of the Department of Homeland Security’s most lucrative contracts are for software and tech gear from a variety of different vendors. A small share of workers at some of those suppliers, including Google, Amazon, and Palantir, have raised concerns for years about whether the technology they are developing is being used for surveillance or to carry out violence.
In 2019, nearly 1,500 workers at Google signed a petition demanding that the tech giant suspend its work with Customs and Border Protection until the agency stopped engaging in what they said were human rights abuses. More recently, staff at Google’s AI unit asked executives to explain how they would prevent ICE from raiding their offices. (No answers were immediately provided to the workers.)
Employees at Palantir have also recently raised questions internally about the company’s work with ICE, WIRED reported. And over 1,000 people across the tech industry signed a letter last month urging businesses to dump the agency.
The tech companies have largely either defended their work for the federal government or pushed back on the idea that they are assisting it in concerning ways. Some government contracts run through intermediaries, making it challenging for workers to identify which tools an agency is using and for what purposes.
The new petition inside Google aims to renew pressure on the company to, at the very least, acknowledge recent events and any work it may be doing with immigration authorities. It was organized by No Tech for Apartheid, a group of Google and Amazon workers who oppose what they describe as tech militarism, or the integration of corporate tech platforms, cloud services, and AI into military and surveillance systems.
The petition specifically asks Google’s leadership to publicly call for the US government to make urgent changes to its immigration enforcement tactics and to hold an internal discussion with workers about the principles they consider when deciding to sell technology to state authorities. It also demands Google take additional steps to keep its own workforce safe, noting that immigration agents recently targeted an area near a Meta data center under construction.

NordProtect Makes ID Theft Protection a Little Easier—if You Trust That It Works
Once I signed up, I had to fill out several online forms. These include information that might personally identify me, like my Social Security number, phone numbers, email addresses, credit/debit cards, and so on. Filling out the information took about 20 minutes. It’s not effortless, but NordProtect’s interface is clean and intuitive. It puts the information you want to see on top, often alongside brief but informative details, with the option to dive deeper. Notifications are rare, too, so you’re not peppered with distracting alerts.
The exception to this was the first time I logged in. I saw dozens of alerts associated with data breaches that occurred over the past two decades. Once those were dismissed, new notifications were uncommon. The interface can seem a bit too simple. I found it easy to forget exactly what the service was doing for me. NordProtect lacks a mobile app. The website works well enough on a smartphone, but a dedicated app would look better.
NordProtect didn’t provide me with any information or take any actions that had an easily quantifiable impact on my privacy. I looked at each of the 48 data breach alerts that appeared and found that none of them contained worrying information. Much of it was out of date (old passwords, ancient addresses, and so on). Some of it was just straight-up wrong.
NordProtect can offer financial safeguards, but I already have a freeze on my credit, and my bank provides free credit monitoring services. I already use a VPN, so NordVPN wasn’t new to me. The most tangible services I gained were identity theft insurance and access to Incogni. On the other hand, I gained less because I’m already somewhat active in monitoring my personal data. NordProtect would be more valuable if I were starting from scratch.

NordProtect offers monthly, annual, and two-year plans, but the pricing pushes you hard toward yearly subscriptions. Silver is $16, Gold is $24, and Platinum is $32 if you pay monthly. That’s pricey! However, the yearly plans are $84, $114, and $144 for the same tiers, respectively, and the two-year plans are $120/$180/$240.
