Czech central bank invests in digital assets for the first time

The Czech National Bank (CNB) has acquired digital assets for the first time, creating a USD 1 million test portfolio outside its international reserves. The initiative includes Bitcoin, a USD stablecoin, and a tokenised deposit on the blockchain.

The portfolio aims to provide practical experience with digital assets and test related operational processes, without plans for further active investment.

Governor Aleš Michl explained that the idea originated in January 2025 to evaluate decentralised Bitcoin and explore its potential role in diversifying reserves. Discussions later included stablecoins, tokenised deposits, and future payment methods, with insights to be shared over the next two to three years.

The CNB emphasises that the koruna remains the country’s legal tender, while new digital payment and investment methods are increasingly emerging.

The test portfolio will examine the full chain of digital asset management, from technical administration and multi-level approvals to crisis scenarios, security measures, and AML compliance.

The CNB aims to maintain and develop internal expertise, ensuring staff gain practical knowledge transferable across teams. The investment is separated from the central bank’s international reserves and will not influence monetary policy or foreign exchange operations.

Alongside the portfolio, the CNB has launched CNB Lab, an innovation hub to test digital assets, blockchain solutions, AI tools, and payment innovations. The Lab will help the bank prepare for the future of finance while building practical experience and team expertise.

Explainable AI predicts cardiovascular events in hospitalised COVID-19 patients

In the article published by BMC Infectious Diseases, researchers developed predictive models using machine learning (LightGBM) to identify cardiovascular complications (such as arrhythmia, acute heart failure, myocardial infarction) in 10,700 hospitalised COVID-19 patients across Brazil.

The study reports moderate discriminatory performance, with AUROC values of 0.752 and 0.760 for the two models, and high overall accuracy (~94.5%) due to the large majority of non-event cases.

However, due to the rarity of cardiovascular events (~5.3% of cases), the F1-scores for detecting the event class remained very low (5.2% and 4.2%, respectively), signalling that the models struggle to reliably identify the minority class despite efforts to rebalance the data.

Using SHAP (Shapley Additive exPlanations) values, the researchers identified the most influential predictors: age, urea level, platelet count and SatO₂/FiO₂ (oxygen saturation to inspired oxygen fraction) ratio.

The authors emphasise that while the approach shows promise for resource-constrained settings and contributes to risk stratification, the limitations around class imbalance and generalisability remain significant obstacles for clinical use.

New AI platforms approved for Surrey Schools classrooms

Surrey Schools has approved MagicSchool, SchoolAI, and TeachAid for classroom use, giving teachers access through the ONE portal with parental consent. The district says the tools are intended to support instruction while maintaining strong privacy and safety safeguards.

Officials say each platform passes rigorous reviews covering educational value, data protection, and technical security before approval. Teachers receive structured guidance on appropriate use, supported by professional development aligned with wider standards for responsible AI in education.

A two-year digital literacy programme helps staff explore online identity, digital habits, and safe technology use as AI becomes more common in lessons. Students use AI to generate ideas, check code, and analyse scientific or mathematical problems, reinforcing critical reasoning.

Educators stress that pupils are taught to question AI outputs rather than accept them at face value. Leaders argue this approach builds judgment and confidence, preparing young people to navigate automated systems with greater agency beyond school settings.

Families and teachers can access AI safety resources through the ONE platform, including videos, podcasts and the ‘Navigating an AI Future’ series. Materials include recordings from earlier workshops and parent sessions, supporting shared understanding of AI’s benefits and risks across the community.

AI could cut two-thirds of UK retail jobs

Automation and AI could drastically reduce jobs at one of the UK’s largest online retailers. Buy It Direct, which employs over 800 staff, predicts more than 500 positions may be lost within three years, as AI and robotics take over office and warehouse roles.

Chief executive Nick Glynne cited rising national living wage and insurance contributions as factors accelerating the company’s shift towards automation.

The firm has already started outsourcing senior roles overseas, including accountants, managers and IT specialists, in response to higher domestic costs.

HM Treasury defended its policies, highlighting reforms in business rates and international trade deals, alongside a capped corporation tax at 25%.

Meanwhile, concerns are growing across the UK about AI replacing jobs, with graduates in fields such as graphic design and computer science facing increasing competition from technological advancements.

ElevenLabs recreates celebrity voices for digital content

Matthew McConaughey and Michael Caine have licensed their voices to ElevenLabs, an AI company, joining a growing number of celebrities who are embracing generative AI. McConaughey will allow his newsletter to be translated into Spanish using his voice, while Caine’s voice is available on ElevenLabs’ text-to-audio app and Iconic Marketplace. Both stressed that the technology is intended to amplify storytelling rather than replace human performers.

ElevenLabs offers a range of synthetic voices, including historical figures and performers like Liza Minnelli and Maya Angelou, while claiming a ‘performer-first’ approach focused on consent and creative authenticity. The move comes amid debate in Hollywood, with unions such as SAG-AFTRA warning AI could undermine human actors, and some artists, including Guillermo del Toro and Hayao Miyazaki, publicly rejecting AI-generated content.

Despite concerns, entertainment companies are investing heavily in AI. Netflix utilises it to enhance recommendations and content, while directors and CEOs argue that it fosters creativity and job opportunities. Critics, however, caution that early investments could form a volatile bubble and highlight risks of misuse, such as AI-generated endorsements or propaganda using celebrity likenesses.

Coding meets creativity in Minecraft Education’s AI tutorial

Minecraft Education is introducing an AI-powered twist on the classic first night challenge with a new Hour of AI world. Players explore a puzzle-driven environment that turns early survival stress into a guided coding and learning experience.

The activity drops players into a familiar biome and tasks them with building shelter before sunset. Instead of panicking at distant rustles or looming shadows, learners work with an AI agent designed to support planning and problem-solving.

Using MakeCode programming, players teach their agent to recognise patterns, classify resources, and coordinate helper bots. The agent mimics real AI behaviour by learning from examples and occasionally making mistakes that require human correction to improve its decisions.

As the agent becomes more capable, it shifts from a simple tool to a partner that automates key tasks and reduces first-night pressure. The aim is to let players develop creative strategies rather than resort to frantic survival instincts.

Designed for ages seven and up, the experience is free to access through Minecraft Education. It introduces core AI literacy concepts, blending gameplay with lessons on how AI systems learn, adapt, and occasionally fail, all wrapped in a familiar, family-friendly setting.

Qwen relaunch aims to unify Alibaba’s mobile AI ecosystem

Alibaba is preparing a major overhaul of its mobile AI apps, renaming Tongyi as Qwen and adding early agentic features. The update aims to make Qwen resemble leading chatbots while linking AI tools to Taobao and other services. Alibaba also plans a global version once the new design stabilises.

Over one hundred developers are working on the project as part of wider AI investments. Alibaba hopes Qwen can anchor its consumer AI strategy and regain momentum in a crowded market. It still trails Doubao and Yuanbao in user popularity and needs a clearer consumer path.

Monetisation remains difficult in China because consumers rarely pay for digital services. Alibaba thinks shopping features will boost adoption by linking AI directly to e-commerce use. Qwen will stay free for now, allowing the company to scale its user base before adding paid options.

Alibaba wants to streamline its overlapping apps by directing users to one unified Qwen interface. Consolidation is meant to strengthen brand visibility and remove confusion around different versions. A single app could help Alibaba stand out as Chinese firms race to deploy agentic AI.

Chinese and US companies continue to expand spending on frontier AI models, cloud infrastructure, and agent tools. Alibaba reported strong cloud growth and rising demand for AI products in its latest quarter. The Qwen relaunch is its largest attempt to turn technical progress into a viable consumer business.
