US extracts rare earths from hard drives, strikes blow to China's dominance

Yahoo22-04-2025
With rare earth exports caught in the crossfire of rising U.S.–China tariffs, the global tech and defense industries are bracing for supply disruptions.
On April 4, China imposed new restrictions on seven critical rare earth elements and magnets, requiring export licenses and delaying outbound shipments.
The move came in direct response to U.S. tariffs of up to 145 percent and has shaken markets reliant on these strategic materials. The tariffs on China have since then shot up to an astonishing 245 percent.
More than half of the United States' supply of critical minerals currently comes from China.
Now, a domestic recycling initiative may offer a way out of this dependence by turning discarded data center hardware into a reliable, eco-friendly source of rare earths and valuable metals.
In a first-of-its-kind pilot, Western Digital, Microsoft, Critical Materials Recycling (CMR), and PedalPoint Recycling processed nearly 50,000 pounds of decommissioned hard drives and server hardware.
Using a new acid-free chemical method, the team extracted rare earth elements like Neodymium, Praseodymium, and Dysprosium, as well as high-purity gold, copper, aluminum, and steel.
The recycled materials are already feeding back into supply chains supporting electric vehicles, wind energy, and next-generation electronics.
At the heart of the process is acid-free dissolution recycling (ADR), a technology developed by the Critical Materials Innovation (CMI) Hub.
The pilot reached a 90 percent recovery rate for rare earths and base metals, along with 80 percent total material recovery by mass.
'This initiative sets a new standard for end-of-life data storage management,' said Jackie Jung, vice president of Global Operations Strategy and Corporate Sustainability at Western Digital.
'This project is more than a milestone. It's a model for sustainable progress in critical material recovery.'
The process also delivers major environmental gains. According to a life cycle analysis, it reduces greenhouse gas emissions by 95 percent compared to conventional mining and refining.
The pilot drew materials from Microsoft data centers across the U.S., underscoring its potential for scalability.
Chuck Graham, corporate vice president at Microsoft, said the results show it's possible to build an economically viable and sustainable system for handling decommissioned hard drives.
'It's an opportunity to reuse and recycle materials, cut waste, and reduce carbon impacts across our entire sector,' Graham said.
The implications stretch beyond corporate sustainability. By performing the entire rare earth oxide production process domestically, the program boosts national security while reducing exposure to volatile global markets.
With international trade policies becoming more unpredictable, securing a homegrown supply chain has become a top strategic priority for the U.S.
Tom Lograsso, director of the CMI Hub, praised the team's rapid development. 'Scaling ADR from lab bench to demonstration scale in just eight years is an incredible achievement,' he said.
With demand for hard drives climbing in tandem with AI and data storage growth, the potential to recover rare earths at scale offers a long-term solution for the U.S.
'This pilot shows what's possible when industry leaders collaborate,' said Brian Diesselhorst, CEO of PedalPoint Recycling. 'The impact could be massive.'
As geopolitical tensions rise, a domestic answer to rare earth supply may no longer be optional, it may be essential.

9 essential Perplexity AI search tips and tricks

All right, settle in, folks, because today we're going to try to out-Google Google with the next generation of search: Perplexity. So, what exactly is Perplexity, and how's it different from other AI chatbots like Gemini, ChatGPT, and Microsoft Copilot? Gemini, ChatGPT, and Copilot are primarily generative AI tools meant for creating text, writing code, brainstorming ideas, and engaging in free-form conversations. They 'generate' stuff based on their training data. Perplexity is an answer engine. Its main job is to give you accurate, sourced answers to your questions by searching the internet in real time. It's built for research and fact-finding. Instead of just generating text, it's designed to summarize, synthesize, and cite information from across the web. And the best part? A lot of Perplexity's brainpower is available right out of the box for free, no wallet required. Let's take things for a spin using one overarching example throughout: the rapid evolution of electric vehicle (EV) battery technology. Ask your question like a human Perplexity understands natural language. Just type your question clearly, like you're asking a person: 'What are the latest breakthroughs in EV battery technology?' Choose your sources This is where you tell Perplexity where to look. Even with the free version, you get access to powerful source filters. Look for the 'Set sources for search' dropdown in the lower-right corner of the search box. It looks like a globe. Web (default) is for general news, current events, popular sites, and the like. For our EV example, this is perfect for getting an overview of 'What are the latest breakthroughs in EV battery technology?' It'll pull from tech blogs, auto news, and general science sites. Academic sources is for scientific papers, scholarly articles, and research journals. Think: 'Detailed chemical mechanisms of solid-state battery electrolytes.' Social sources is for discussions, opinions, and real-world experiences from real people. Use Social and ask, 'What are consumer experiences with EV range anxiety for new battery types?' And Finance sources is best for market data, company reports, and investment news: 'Investment trends for companies developing next-gen EV batteries.' Follow up, then follow up some more Perplexity is designed for conversation. After it gives you an answer, you can ask follow-up questions within the same thread. Our initial 'Web' search about EV battery breakthroughs mentioned 'silicon anode technology.' advertisement You can then type, 'How does silicon anode technology impact charging times?' or, 'What are the main challenges in using silicon anodes in mass production?' Perplexity will remember your previous questions, making the conversation seamless. Double-check the sources Every single piece of information Perplexity gives you comes with clickable source citations. If Perplexity states, 'Solid-state batteries offer higher energy density (Source 1) and faster charging (Source 2),' those little numbers are links. Click them to jump directly to the original article, research paper, or news report. This lets you fact-check Perplexity's summary and see the information in its original context. Leverage your daily free 'Pro Searches' Perplexity gives free users a limited number of Pro Searches per day. Think of these as a daily allowance of super-powered queries. When you toggle on Pro Search (the looping X icon in the lower-left of the search box), Perplexity uses its most advanced AI models and a deeper search strategy. Save these for when your question is complex, highly nuanced, or when a regular search isn't quite hitting the mark. For example, if you're trying to compare the long-term cost-effectiveness of different EV battery chemistries, a Pro Search can often provide a more detailed and structured analysis. Other general tips So there you have it: Your crash course in getting started with Perplexity's free features, all framed around the fascinating world of EV battery tech. Some other quick tips . . .

Chinese hackers breach US nuclear security agency in cyberattack operation, officials say

A sweeping cyberattack breached the U.S. National Nuclear Security Administration (NNSA) through Microsoft's Sharepoint document software, the Energy Department confirmed to Fox News Digital on Wednesday. The agency does not know of any sensitive or classified information that has been stolen at this time. "On Friday, July 18th, the exploitation of a Microsoft SharePoint zero-day vulnerability began affecting the Department of Energy, including the NNSA," a Department of Energy (DoE) told Fox News Digital, referring to the agency responsible for maintaining and designing the nation's nuclear weapons stockpiles. MICROSOFT ENDS USE OF CHINA-BASED COMPUTER ENGINEERS FOR CERTAIN DEFENSE DEPT PROJECTS AMID ESPIONAGE FEARS Microsoft warned that Chinese state-sponsored actors were exploiting flaws in the SharePoint software of institutions across the globe. Netherlands-based Eye Security told Reuters the breach has now claimed 400 victims. Linen Typhoon and Violet Typhoon, the two groups backed by the CCP involved in the hack, utilized flaws in the document-sharing software that exist for customers who run it on their own networks rather than through Microsoft's cloud software. But DoE said it largely utilizes the cloud, so only a "very small number of systems were impacted." "All impacted systems are being restored." Another hacking group based in China, Storm-2603, also exploited the vulnerabilities, according to Microsoft. Asked about the hack on Wednesday, Chinese foreign ministry spokesperson Guo Jiakun said he wasn't aware of the specifics, but: "China opposes and fights hacking activities in accordance with the law. At the same time, we oppose smears and attacks against China under the excuse of cybersecurity issues." Charles Carmakal, technology chief of the Google-owned Mandiant cybersecurity consulting group, confirmed Monday in a LinkedIn post that at least one of the organizations involved in the hack was a "China-nexus threat actor." NATIONAL SECURITY EXPERTS RAISE CONCERNS AFTER MICROSOFT PROGRAM EXPOSED AS POSSIBLE AVENUE FOR CHINESE SPYING On Sunday, the U.S. Cybersecurity and Infrastructure Security Agency said it was "aware of active exploitation" of the SharePoint vulnerability. CLICK HERE TO GET THE FOX NEWS APP Microsoft CEO Satya Nadella vowed last year to make cybersecurity a top priority after a government report criticized the company's handling of a Chinese breach of the emails of U.S. government officials. Just last week, the company vowed to stop using engineers based in China to provide technical support for clients within the Defense Department using the company's cloud services. That came after a ProPublica report revealed the practice and said it could expose the DoD to Chinese hackers.

The Outer Worlds 2 will no longer be Microsoft's first $80 Xbox game

Microsoft-owned developer Obsidian Entertainment is announcing a price drop for the The Outer Worlds 2 today. The game was originally supposed to debut at $79.99 in October, but it's now going back to the regular $69.99 Xbox game price. Microsoft announced earlier this year that it would be raising the price of new Xbox first-party games from $69.99 to $79.99, alongside increases to its consoles and controllers. The move to suddenly drop the price of The Outer Worlds 2 is a clear sign that preorders haven't gone too well and that gamers are rejecting Microsoft's initial move to $79.99 Xbox games. If you've already purchased the game then refunds will be handled by the Microsoft Store, Steam, PlayStation store or wherever you preordered The Outer Worlds 2. Other first-party Xbox games coming this holiday will also be sold at $69.99, instead of Microsoft's new $79.99 pricing. 'We're focused on bringing players incredible worlds to explore, and will keep our full priced holiday releases, including The Outer Worlds 2, at $69.99 – in line with current market conditions,' says an unnamed Xbox spokesperson in a statement to IGN. It will be interesting to see whether Microsoft continues to push its new Xbox game pricing in the new year, or whether this is a sign that it's fully rethinking the increase to $79.99.
