Emergency cardiology gets a lift from AI-read ECGs, with fewer false activations

AI ECG analysis improved heart attack detection and reduced false alarms in a multicentre study of 1,032 suspected STEMI cases. Conducted across three primary PCI centres from January 2020 to May 2024, it points to quicker, more accurate triage, especially beyond specialist hospitals.

ST-segment elevation myocardial infarction occurs when a major coronary artery is blocked. Guideline targets call for reperfusion within 90 minutes of first medical contact. Longer delays are associated with roughly a 3-fold increase in mortality, underscoring the need for rapid, reliable activation.

The AI ECG model, trained to detect acute coronary occlusion and STEMI equivalents, analysed each patient’s initial tracing. Confirmatory angiography and biomarkers identified 601 true STEMIs and 431 false positives. AI detected 553 of 601 STEMIs, versus 427 identified by standard triage on the first ECG.

False positives fell sharply with AI. Investigators reported a 7.9 percent false-positive rate with the model, compared with 41.8 percent under standard protocols. Clinicians said earlier that more precise identification could streamline transfers from non-PCI centres and help teams reach reperfusion targets.

An editorial welcomed the gains but urged caution. The model targets acute occlusion rather than STEMI, needs prospective validation in diverse populations, and must be integrated with clear governance and human oversight.

NVIDIA and Nokia join forces to build the AI platform for 6G

Nokia and NVIDIA have announced a $1 billion partnership to develop an AI-powered platform that will drive the transition from 5G to 6G networks.

The collaboration will create next-generation AI-RAN systems, combining computing, sensing and connectivity to transform how the US mobile networks process data and deliver services.

However, this partnership marks a strategic step in both companies’ ambition to regain global leadership in telecommunications.

By integrating NVIDIA’s new Aerial RAN Computer and Nokia’s AI-RAN software, operators can upgrade existing networks through software updates instead of complete infrastructure replacements.

T-Mobile US will begin field tests in 2026, supported by Dell’s PowerEdge servers.

NVIDIA’s investment and collaboration with Nokia aim to strengthen the foundation for AI-native networks that can handle the rising demand from agentic, generative and physical AI applications.

These networks are expected to support future 6G use cases, including drones, autonomous vehicles and advanced augmented reality systems.

Both companies see AI-RAN as the next evolution of wireless connectivity, uniting data processing and communication at the edge for greater performance, energy efficiency and innovation.

Most Greeks have never used AI at work

A new Focus Bari survey shows that AI is still unfamiliar territory for most Greeks.

Although more than eight in ten have heard of AI, 68 percent say they have never used it professionally. The study highlights that Greece integrates AI into its workplace more slowly than many other countries.

The survey covered 21 nations and found that 83 percent of Greeks know about AI, compared with 17 percent who do not. Only 35 percent feel well-informed, while about one in three admits to knowing little about the technology.

Similar trends appear worldwide, with Switzerland, Mexico, and Romania leading in AI awareness, while countries like Nigeria, Japan, and Australia show limited familiarity.

Globally, almost half of respondents use AI in their everyday lives, yet only one in three applies it in their work. In Greece, that gap remains wide, suggesting that AI is still seen as a distant concept rather than a professional tool.

UNESCO surveys women on AI fairness and safety

UNESCO’s Office for the Caribbean has launched a regional survey examining gender and AI, titled Perception of AI Fairness and Online Safety among Women and Girls in the Caribbean. The initiative addresses the lack of data on how women and girls experience technology, AI, and online violence in the region.

Results will guide policy recommendations to promote human rights and safer digital environments.

The 2025 survey is part of a broader UNESCO effort to understand AI’s impact on gender equality. It covers gender-based online violence, generative AI’s implications for privacy, and potential biases in large AI models.

The findings will be used to develop a regional policy brief compared with global data.

UNESCO encourages participation from women and girls across the Caribbean, highlighting that community input is vital for shaping effective AI policies. A one-day workshop on 10 December 2025 will equip young women with skills to navigate AI safely.

The initiative aims to position the Caribbean as a leader in ensuring AI respects dignity, equality, and human rights.

Adobe launches AI Assistant to simplify creative design

Adobe has launched a new AI Assistant in Express, enabling users to create and edit content from concept to completion in minutes. The tool understands design context and lets users create on-brand visuals by describing their ideas.

Users can seamlessly adjust fonts, images, backgrounds, and other elements while keeping the rest of the design intact.

The AI Assistant integrates generative AI models with Adobe’s professional tools, turning templates into conversational canvases. Users can make targeted edits, replace objects, or transform designs without starting over.

The assistant also interprets subjective requests, suggesting creative options and offering contextual prompts to refine results efficiently, enhancing both speed and quality of content creation.

Adobe Express will extend the AI Assistant with enterprise-grade features, including template locking, batch creation, and brand consistency tools. Early adopters report that non-designers can now produce professional visuals quickly, while experienced designers save time on routine tasks.

Organisations can expect improved collaboration, efficiency, and consistency across content supply chains.

The AI Assistant beta is currently available to Adobe Express Premium customers on desktop, with full availability planned for all users via the Firefly generative credit system. Adobe stresses that AI enhances creativity, respects creators’ rights, and supports responsible generative AI use.

AI-driven diabetes prevention matches human-led programs in clinical trial

Researchers at Johns Hopkins Medicine and the Bloomberg School of Public Health report that an AI-driven diabetes prevention program achieved outcomes comparable to traditional, human-led coaching. The results come from a phase III randomised controlled trial, the first of its kind.

The trial enrolled participants with prediabetes and randomly assigned them to one of four remote human-led programs or an AI app that delivered personalised push notifications guiding diet, exercise and weight management. Over 12 months, both groups were evaluated against CDC benchmarks for risk reduction (e.g. achieving 5 % weight loss, meeting activity goals, or reducing A1C).

After one year, 31.7 % of AI-app users and 31.9 % of human-led participants met the composite benchmark. Interestingly, the AI arm saw higher initiation rates (93.4 % vs 82.7 %) and completion (63.9 % vs 50.3 %) than human programs.

The researchers note that scheduling, staffing, and access barriers can limit traditional lifestyle programs. The AI approach, which runs asynchronously and is always available, may help expand reach, especially for underserved populations or when human resources are constrained.

Future work will assess how these findings scale in broader, real-world patient groups and explore cost effectiveness, user preferences and the balance between AI and human support.

OpenAI and Microsoft sign new $135 billion agreement to deepen AI partnership

Microsoft and OpenAI have signed a new agreement that marks the next phase of their long-standing partnership, deepening ties first formed in 2019.

The updated deal builds on years of collaboration in advancing responsible AI, positioning both organisations for long-term success while introducing new structural and operational changes.

Under the new arrangement, Microsoft supports OpenAI’s transition into a public benefit corporation (PBC) and recapitalisation. The technology giant now holds an investment valued at around $135 billion, representing about 27 percent of OpenAI Group PBC on an as-converted diluted basis.

Despite OpenAI’s recent funding rounds, Microsoft previously held a 32.5 percent stake in the for-profit entity.

The partnership maintains Microsoft’s exclusive rights to OpenAI’s frontier models and Azure API until artificial general intelligence (AGI) is achieved, but also introduces several new terms. Once AGI is declared, an independent panel will verify it.

Microsoft’s intellectual property rights are extended through 2032, including models developed after AGI with safety conditions. OpenAI may now co-develop certain products with third parties, while retaining the option to serve non-API products on any cloud provider.

OpenAI will purchase an additional $250 billion worth of Azure services, although Microsoft will no longer hold first-refusal rights for compute supply. The new framework allows both organisations to innovate independently, with Microsoft permitted to pursue AGI independently or with other partners.

The updated agreement reflects a more flexible collaboration that balances independence, growth, and shared innovation.

Yuan says AI ‘digital twins’ could trim meetings and the workweek

AI could shorten the workweek, says Zoom’s Eric Yuan. At TechCrunch Disrupt, he pitched AI ‘digital twins’ that attend meetings, negotiate drafts, and triage email, arguing assistants will shoulder routine tasks so humans focus on judgement.

Yuan has already used an AI avatar on an investor call to show how a stand-in can speak on your behalf. He said Zoom will keep investing heavily in assistants that understand context, prioritise messages, and draft responses.

Use cases extend beyond meetings. Yuan described counterparts sending their digital twins to hash out deal terms before principals join to resolve open issues, saving hours of live negotiation and accelerating consensus across teams and time zones.

Zoom plans to infuse AI across its suite, including whiteboards and collaborative docs, so work moves even when people are offline. Yuan said assistants will surface what matters, propose actions, and help execute routine workflows securely.

If adoption scales, Yuan sees schedules changing. He floated a five-year goal where many knowledge workers shift to three or four days a week, with AI increasing throughput, reducing meeting load, and improving focus time across organisations.

Amazon plans up to 30,000 corporate job cuts as AI automation expands

Beginning Tuesday, Amazon plans to cut up to 30,000 corporate roles, nearly 10% of its white-collar workforce, to reduce costs after pandemic over-hiring.

Cuts may hit human resources, operations, devices and services, and Amazon Web Services. According to people familiar with the policy, the company has also tightened office-attendance rules; employees who are not swiping in daily have been told they are considered to have resigned without severance.

Analysts say AI-driven productivity gains and the need to fund long-term AI infrastructure are key factors behind the reductions in staff. Executives have indicated that greater use of automation and AI to handle routine tasks will drive further reductions.

Internal planning papers reported in US media suggest the company could avoid hiring more than 500,000 US workers by 2033, yielding around $12.6 billion in savings between 2025 and 2027.

The scale and timing of the layoffs could change as financial priorities evolve. Separately, Amazon still expects a busy holiday period and plans to hire 250,000 seasonal workers for warehouses and fulfilment roles unrelated to the corporate cuts.
