New US tariffs on advanced AI chips are drawing scrutiny over their impact on global supply chains, with South Korea monitoring potential effects on its semiconductor industry.
The US administration has approved a 25 percent tariff on advanced chips that are imported into the US and then re-exported to third countries. The measure is widely seen as aimed at restricting the flow of AI accelerators to China.
The tariff thresholds are expected to cover processors such as Nvidia’s H200 and AMD’s MI325X, which rely on high-bandwidth memory supplied by Samsung Electronics and SK hynix.
Industry officials say most memory exports from South Korea to the US are used in domestic data centres, which are exempt under the proclamation, reducing direct exposure for suppliers.
South Korea’s trade ministry has launched consultations with industry leaders and US counterparts to assess risks and ensure Korean firms receive equal treatment to competitors in Taiwan, Japan and the EU.

Scientists in Chinadeveloped an error-aware probabilistic update (EaPU) to improve neural network training on memristor hardware. The method tackles accuracy and stability limits in analog computing.
Training inefficiency caused by noisy weight updates has slowed progress beyond inference tasks. EaPU applies probabilistic, threshold-based updates that preserve learning and sharply reduce write operations.
Experiments and simulations show major gains in energy efficiency, accuracy and device lifespan across vision models. Results suggest broader potential for sustainable AI training using emerging memory technologies.

Several UK professional organisations for tax practitioners, including the Chartered Institute of Taxation (CIOT) and the Society of Trust and Estate Practitioners (STEP), have published new AI guidance for members.
The documents aim to help tax professionals understand how to adopt AI tools securely and responsibly while maintaining professional standards and compliance with legal and regulatory frameworks.
The guidance stresses that members should be aware of risks associated with AI, including data quality, bias, model limitations and the need for human oversight. It encourages firms to implement robust governance, clear policies on use, appropriate training and verification processes where outputs affect client advice or statutory obligations.
By highlighting best practices, the professional bodies seek to balance the benefits of generative AI, such as improved efficiency and research assistance, with ethical considerations and core professional responsibilities.
The guidance also points to data-protection obligations under UK law and the importance of maintaining client confidentiality when using third-party AI systems.

Industry expectations around SEO are shifting as AI agents increasingly rely on existing search infrastructure, according to James LePage, co-lead of the WordPress AI team at Automattic.
Search discovery for AI systems continues to depend on classic signals such as links, authority and indexed content, suggesting no structural break from traditional search engines.
Publishers are therefore being encouraged to focus on semantic markup, schema and internal linking, with AI optimisation closely aligned to established long-tail search strategies.
Future-facing content strategies prioritise clear summaries, ranked information and progressive detail, enabling AI agents to reuse and interpret material independently of traditional websites.

South Africa’s rate of AI implementation is roughly half that of the US, according to insights from Specno. Analysts attribute the gap to shortages in skills, weak data infrastructure and limited alignment between AI projects and core business strategy.
Despite moderate AI readiness levels, execution remains a major challenge across South African organisations. Skills shortages, insufficient workforce training and weak organisational readiness continue to prevent AI systems from moving beyond pilot stages.
Industry experts say many executives recognise the value of AI but struggle to adopt it in practice. Constraints include low IT maturity, risk aversion and organisational cultures that resist large-scale transformation.
By contrast, companies in the US are embedding AI into operations, talent development and decision-making. Analysts say South Africa must rapidly improve executive literacy, data ecosystems and practical skills to close the gap.

Rising AI-driven electricity demand is straining power grids and renewing focus on nuclear energy as a stable, low-carbon solution. Data centres powering AI systems already consume electricity at the scale of small cities, and demand is accelerating rapidly.
Global electricity consumption could rise by more than 10,000 terawatt-hours by 2035, largely driven by AI workloads. In advanced economies, data centres are expected to drive over a fifth of electricity-demand growth by 2030, outpacing many traditional industries.
Nuclear energy is increasingly positioned as a reliable backbone for this expansion, offering continuous power, high energy density, and grid stability.
Governments, technology firms, and nuclear operators are advancing new reactor projects, while long-term power agreements between tech companies and nuclear plants are becoming more common.
Alongside large reactors, interest is growing in small modular reactors designed for faster deployment near data centres. Supporters say these systems could ease grid bottlenecks and deliver dedicated power for AI, strengthening nuclear energy’s role in the digital economy.

US regulators have closed a loophole that allowed Elon Musk’s AI company, xAI, to operate gas-burning turbines at its Memphis data centre without full air pollution permits. The move follows concerns over emissions and local health impacts.
The US Environmental Protection Agency clarified that mobile gas turbines cannot be classified as ‘non-road engines’ to avoid Clean Air Act requirements. Companies must now obtain permits if their combined emissions exceed regulatory thresholds.
Local authorities had previously allowed the turbines to operate without public consultation or environmental review. The updated federal rule may slow xAI’s expansion plans in the Memphis area.
The Colossus data centre, opened in 2024, supports training and inference for Grok AI models and other services linked to Musk’s X platform. NVIDIA hardware is used extensively at the site.
Residents and environmental groups have raised concerns about air quality, particularly in nearby communities. Legal advocates say xAI’s future operations will be closely monitored for regulatory compliance.

The European Commission plans to revise the Cybersecurity Act to expand certification schemes beyond ICT products and services. Future assessments would also cover companies’ overall risk-management posture, including governance and supply-chain practices.
Only one EU-wide scheme, the Common Criteria framework, has been formally adopted since 2019. Cloud, 5G, and digital identity certifications remain stalled due to procedural complexity and limited transparency under the current Cybersecurity Act framework.
The reforms aim to introduce clearer rules and a rolling work programme to support long-term planning. Managed security services, including incident response and penetration testing, would become eligible for EU certification.
ENISA would take on a stronger role as the central technical coordinator across member states. Additional funding and staff would be required to support its expanding mandate under the newer cybersecurity laws.
Stakeholders broadly support harmonisation to reduce administrative burden and regulatory fragmentation. The European Commission says organisational certification would assess cybersecurity maturity alongside technical product compliance.

Canada’s investment regulator has confirmed a major data breach affecting around 750,000 people after a phishing attack in August 2025.
The Canadian Investment Regulatory Organization (CIRO) said threat actors accessed and copied a limited set of investigative, compliance, and market surveillance data. Some internal systems were taken offline as a precaution, but core regulatory operations continued across the country.
CIRO reported that personal and financial information was exposed, including income details, identification records, contact information, account numbers, and financial statements collected during regulatory activities in Canada.
No passwords or PINs were compromised, and the organisation said there is no evidence that the stolen data has been misused or shared on the dark web.
Affected individuals are being offered two years of free credit monitoring and identity theft protection as CIRO continues to monitor for further malicious activity nationwide.
