Microwave tech offers cleaner path to e-waste recovery

When your old phone or computer reaches the end of its life and heads off for recycling, most of its valuable materials—like steel, aluminium and copper—are recovered with ease. But hidden in its circuitry are tiny specks of rare metals such as gallium, indium and tantalum.

These are critical to modern technology but often lost in current recycling processes, ending up in landfills or repurposed in cement. That might be about to change.

Engineers at West Virginia University have developed a novel method using microwave technology to extract these rare materials more safely and efficiently.

Unlike conventional methods, which rely on toxic chemicals or are too costly to justify, this approach uses electromagnetic waves to target and heat carbon present in e-waste plastics. This creates a reaction with critical minerals, yielding nearly pure, sponge-like metals that can be easily filtered out.

Laboratory tests have already recovered around 80% of gallium, indium and tantalum from e-waste, with purities reaching up to 97%.

Backed by the United States Department of Defense, the researchers are preparing larger pilot projects using smartphones, LED lights and server boards—materials rich in these rare elements. If scaled successfully, the system could recover up to 50 pounds of critical minerals per ton of processed waste.

The urgency is clear. America recycles just 15% of its e-waste, and much of it is exported to countries with lax safety and environmental standards. Gallium alone can cost over $500 per kilogram—making it 50 times more expensive than copper.

The technology’s success could help shift the economics of recycling, turning discarded electronics into a domestic supply of essential materials and reducing reliance on imports from countries like China.

Panama City considers Bitcoin for canal payments

Panama City’s Mayor Mayer Mizrachi has floated the idea of letting cargo ships pay in Bitcoin. The proposal would allow faster passage through the Panama Canal, one of the world’s most vital trade routes.

Speaking at the Bitcoin 2025 conference in Las Vegas, he suggested offering perks to vessels choosing Bitcoin as a payment method. The canal processes nearly 10,000 ships a year and accounts for around 5% of global maritime trade.

Mizrachi’s proposal comes as part of his broader effort to integrate Bitcoin into public infrastructure. Panama City began accepting crypto for municipal payments in April, instantly converting transactions into dollars.

The mayor is also exploring the creation of a Bitcoin reserve and has sought inspiration from El Salvador’s pro-Bitcoin policies.

The idea of crypto payments for canal fees emerges amid rising international interest in the waterway. Mizrachi, however, urged lawmakers not to rush into restrictive crypto regulation, advocating instead for a hands-off approach.

While the Bitcoin-for-passage concept remains in its early stages, Mizrachi claims crypto use in Panama is more widespread than it appears, with over $5 billion in annual transactions.

Paris Saint-Germain adds Bitcoin to treasury

Paris Saint-Germain (PSG) has revealed it holds Bitcoin in its treasury, becoming the first sports club to make such a move public. The announcement was made during the Bitcoin 2025 conference in Las Vegas by Pär Helgosson, head of PSG Labs.

He called it part of a ‘new generation trend,’ reflecting the club’s efforts to align with future-facing innovations.

The club began acquiring Bitcoin last year, converting part of its fiat reserves into the digital asset. Helgosson highlighted the relevance of the decision by pointing out that 80% of PSG’s global fanbase is under the age of 34.

With over 550 million fans worldwide, the move positions PSG as a leader among sports organisations adapting to the digital economy.

Football remains the most active sport for crypto sponsorships, accounting for 43% of all crypto deals in the 2024/25 season, according to SportQuake.

The trend has seen a 64% annual increase, driven largely by European leagues and global campaigns amid political uncertainty in the US.

PSG joins a growing number of institutions adding Bitcoin to their balance sheets. Analysts credit both exchange-traded funds (ETFs) and political momentum, particularly under President Trump’s administration, for boosting corporate confidence in Bitcoin as a strategic asset.

Uber’s product chief turns to AI for reports and research

Uber’s chief product officer, Sachin Kansal, is embracing AI to streamline his daily workflow—particularly through tools like ChatGPT, Google Gemini, and, soon, NotebookLM.

Speaking on ‘Lenny’s Podcast,’ Kansal revealed how AI summarisation helps him digest lengthy 50- to 100-page reports he otherwise wouldn’t have time to read. He uses AI to understand market trends and rider feedback across regions such as Brazil, South Korea, and South Africa.

Kansal also relies on AI as a research assistant. For instance, when exploring new driver features, he used ChatGPT’s deep research capabilities to simulate possible driver reactions and generate brainstorming ideas.

‘It’s an amazing research assistant,’ he said. ‘It’s absolutely a starting point for a brainstorm with my team.’

He’s now eyeing Google’s NotebookLM, a note-taking and research tool, as the next addition to his AI toolkit—especially its ‘Audio Overview’ feature, which turns documents into AI-generated podcast-style discussions.

Uber CEO Dara Khosrowshahi previously noted that too few of Uber’s 30,000+ employees are using AI and stressed that mastering AI tools, especially for coding, would soon be essential.

AI copyright clash stalls UK data bill

A bitter standoff over AI and copyright has returned to the House of Lords, as ministers and peers clash over how to protect creative workers while fostering technological innovation.

At the centre of the debate is the proposed Data (Use and Access) Bill, which was expected to pass smoothly but is now stuck in parliamentary limbo due to growing resistance.

The bill would allow AI firms to access copyrighted material unless rights holders opt out, a proposal that many artists and peers believe threatens the UK’s £124bn creative industry.

Nearly 300 Lords have called for AI developers to disclose what content they use and seek licences instead of relying on blanket access. Former film director Baroness Kidron described the policy as ‘state-sanctioned theft’ and warned it would sacrifice British talent to benefit large tech companies.

Supporters of the bill, like former Meta executive Sir Nick Clegg, argue that forcing AI firms to seek individual permissions would severely damage the UK’s AI sector. The Department for Science, Innovation and Technology insists it will only consider changes if they are proven to benefit creators.

If no resolution is found, the bill risks being shelved entirely. That would also scrap unrelated proposals bundled into it, such as new NHS data-sharing rules and plans for a nationwide underground map.

Despite the bill’s wide scope, the fight over copyright remains its most divisive and emotionally charged feature.

Gmail adds automatic AI summaries

Gmail on mobile now displays AI-generated summaries by default, marking a shift in how Google’s Gemini assistant operates within inboxes.

Instead of relying on users to request a summary, Gemini will now decide when it’s useful—typically for long email threads with multiple replies—and present a brief summary card at the top of the message.

These summaries update automatically as conversations evolve, aiming to save users from scrolling through lengthy discussions.

The feature is currently limited to mobile devices and available only to users with Google Workspace accounts, Gemini Education add-ons, or a Google One AI Premium subscription. For the moment, summaries are confined to emails written in English.

Google expects the rollout to take around two weeks, though it remains unclear when, or if, the tool will extend to standard Gmail accounts or desktop users.

Anyone wanting to opt out must disable Gmail’s smart features entirely—giving up tools like Smart Compose, Smart Reply, and package tracking in the process.

While some may welcome the convenience, others may feel uneasy about their emails being analysed by large language models, especially since this process could contribute to further training of Google’s AI systems.

The move reflects a wider trend across Google’s products, where AI is becoming central to everyday user experiences.

Additional user controls and privacy commitments

According to Google Workspace, users have some control over the summary cards. They can collapse a Gemini summary card, and it will remain collapsed for that specific email thread.

In the near future, Gmail will introduce enhancements, such as automatically collapsing future summary cards for users who consistently collapse them, until the user chooses to expand them again. For emails that don’t display automatic summaries, Gmail still offers manual options.

Users can tap the ‘summarise this email’ chip at the top of the message or use the Gemini side panel to trigger a summary manually. Google also reaffirms its commitment to data protection and user privacy. All AI features in Gmail adhere to its privacy principles, with more details available on the Privacy Hub.

Europe’s digital euro ambitions: A bid for global currency influence

At a recent speech in Berlin, European Central Bank President Christine Lagarde highlighted the potential of the euro to take on a greater international role amid growing uncertainty in the global monetary system. With the dominance of the US dollar increasingly under scrutiny and central banks turning to gold at levels unseen in decades, Lagarde outlined how a digital euro could be pivotal in shifting the balance of global finance.

Lagarde emphasised that the euro already accounts for around 20% of global foreign exchange reserves but still lags far behind the US dollar’s 58%. She argued that a more internationally accepted euro would shield Europe from exchange rate volatility, reduce borrowing costs, and help protect the EU from coercive economic measures.

One of the key steps in this direction is the ongoing development of a digital euro—an initiative the ECB is pursuing to modernise cross-border payments and reinforce the euro’s international utility. The ECB President noted that trade alone won’t be enough to elevate the euro to global reserve status.

Investors also need confidence in Europe’s geopolitical strength and legal institutions. She linked the US dollar’s global standing to its economy, military alliances, and legal predictability—areas where Europe must step up.

A digital euro, supported by robust capital markets and legal credibility, could become a cornerstone in this strategy. Lagarde concluded with a call for bold action.

The global economic landscape is shifting, and Europe must seize this ‘global euro moment.’ But success is not guaranteed, she warned.

For the euro to rise as a true rival to the dollar, the EU must act decisively, invest in unity, and deliver on reforms that inspire trust and stability, both politically and economically.

AI takes over eCommerce tasks as Visa and Mastercard adapt

Visa and Mastercard have announced major AI initiatives that could reshape the future of e-commerce, marking a significant step in the evolution of retail technology.

The initiatives—Visa’s Intelligent Commerce and Mastercard’s Agent Pay—move beyond traditional recommendation engines to empower AI agents to make purchases directly on behalf of consumers.

Visa is partnering with leading tech firms, including Anthropic, IBM, Microsoft, OpenAI, and Stripe, to build a system where AI agents shop according to user preferences.

Meanwhile, Mastercard’s Agent Pay integrates payment functionality into AI-driven conversational platforms, blending commerce and conversation into a seamless user experience.

These announcements follow years of AI integration into retail, with adoption growing at 40% annually and the market projected to surpass $8 billion by 2024. Retailers initially used AI for backend optimisation, but nearly 87% now apply it in customer-facing roles.

The next phase, where AI doesn’t just suggest but acts, is rapidly taking shape—backed by consumer demand for hyper-personalisation and efficiency.

Research suggests 71% of consumers want generative AI embedded in their shopping journeys, with 58% already turning to AI tools over traditional search engines for recommendations. However, consumer trust remains a challenge.

Satisfaction with AI dropped slightly last year, highlighting concerns over privacy and implementation quality—especially critical for financial transactions.

Visa and Mastercard’s moves reflect both opportunity and necessity. With 75% of retailers viewing AI agents as essential within the next year, and AI expected to handle 20% of eCommerce tasks, the payment giants are positioning themselves as indispensable infrastructure in a fast-changing market.

Their broad alliances across AI, payments, and tech underline a shared goal: to stay central as shopping behaviours evolve in the AI era.

Gemini AI can now summarise videos in Google Drive

Google is expanding Gemini AI’s capabilities in Drive by enabling it to analyse video files and respond to user questions or generate concise summaries.

The new feature aims to save users time by providing quick insights from lengthy content such as meetings, classes or announcements, instead of requiring them to watch the entire video. Until now, Gemini could only summarise documents and PDFs stored in Drive.

According to a blog post published on 28 May 2025, the feature will support prompts like ‘Summarise the video’ or ‘List action items from the meeting.’ Users can access Gemini’s functionality either through Drive’s overlay previewer or a standalone viewer in a separate browser tab.

However, captions must be enabled within the user’s domain for the feature to work properly.

The update is being gradually rolled out and is expected to be available to all eligible users by 19 June. At the moment, it is limited to English and accessible only to users of Google Workspace and Google One AI Premium, or those with Gemini Business or Enterprise add-ons.

For administrators, smart features and personalisation settings must be activated to grant access.

To use the new function, users can double-click on a video file in Drive and select the ‘Ask Gemini’ option marked by a star icon in the top right corner. Google says the upgrade reflects a broader effort to integrate AI seamlessly into everyday workflows by making content easier to navigate and understand.
