Power demands reshape future of data centres

As AI and cloud computing demand surges, Siemens is tackling critical energy and sustainability challenges facing the data centre industry. With power densities surpassing 100kW per rack, traditional infrastructure is being pushed beyond its limits.

Siemens highlighted the urgent need for integrated digital solutions to address growing pressures such as delayed grid connections, rising costs, and speed of deployment. Operators are increasingly adopting microgrids and forming utility partnerships to ensure resilience and control over power access.

Siemens views data centres not just as energy consumers but as contributors to the grid, using stored energy to balance supply. The shift is pushing the industry to become more involved in grid stability and renewable integration.

While achieving net zero remains challenging, data centres are adopting on-site renewables, advanced cooling systems, and AI-driven management tools to boost efficiency.

Siemens’ own software, such as the Building X Suite, is helping reduce energy waste and predict maintenance needs, aligning operational effectiveness with sustainability goals.

Eric Schmidt warns that AI growth is limited by electricity

Former Google chief executive Eric Schmidt has warned that electricity, rather than semiconductors, will limit the future growth of AI.

Speaking on the Moonshots podcast, Schmidt said the push towards artificial superintelligence—AI that exceeds human cognitive ability in almost all domains—will depend on securing sufficient power instead of just developing more advanced chips.

Schmidt noted the US alone may require an extra 92 gigawatts of electricity to support AI growth, equivalent to dozens of nuclear power stations.

Instead of waiting for new plants, companies such as Microsoft are seeking to retrofit closed facilities, including the Three Mile Island plant targeted for relaunch in 2028.

Schmidt highlighted growing environmental pressures, citing Microsoft’s 34% increase in water use within a year, a trend experts link directly to rising AI workloads.

Major AI developers like OpenAI’s Sam Altman also acknowledge energy as a key constraint. Altman has invested in nuclear fusion through Helion, while firms such as Microsoft and AMD are pressing US policymakers to fast-track energy permits.

Environmental groups, including Greenpeace, warn that unchecked AI expansion risks undermining climate goals instead of supporting them.

Schmidt believes superintelligence is inevitable and approaching rapidly, predicting specialised AI tools across all fields within five years. Rather than focusing solely on AI’s capabilities, he stressed the urgent need for planning energy infrastructure today to match tomorrow’s AI demands.

Amazon cuts hundreds of AWS jobs amid AI shift

Amazon has reportedly cut hundreds of jobs within its Amazon Web Services cloud computing division, according to sources familiar with the matter.

Instead of providing specific numbers, Amazon confirmed the decision, citing ongoing efforts to optimise resources while continuing to invest in customer-focused innovation.

These layoffs follow warnings by CEO Andy Jassy, who recently said the rising use of generative AI would reduce workforce needs across the company.

The cuts affect several AWS teams, including specialists who support customers in developing new products and selling services. Employees reported receiving termination emails on Thursday, with their system access deactivated soon after.

Rather than focusing solely on AWS, Amazon has also been reducing roles in other units, such as its books division, devices and services unit, and Wondery podcast platform.

Despite these workforce reductions, AWS sales rose 17% in the first quarter to $29.3 billion compared to a year earlier, with operating income increasing by 23% to $11.5 billion.

Amazon, alongside firms like Microsoft, Meta, and CrowdStrike, is increasingly relying on AI tools instead of human workers to automate tasks, write software code, and streamline operations as part of a broader trend affecting the tech industry.

Amazon’s latest cuts reflect efforts by Jassy to reduce bureaucracy and eliminate managerial layers, aiming to keep the company agile amid rapid AI adoption and changing business priorities.

Irish hospital turns to AI for appointment management

Beaumont Hospital in Dublin plans to deploy AI to predict patient no-shows and late cancellations, aiming to reduce wasted resources.

Instead of relying solely on reminders, the hospital will pilot AI software costing up to €110,000, using patient data to forecast missed appointments. Currently, no-shows account for 15.5% of its outpatient slots.

The system will integrate with Beaumont’s existing two-way text messaging service. Rather than sending uniform reminders, the AI model will tailor messages based on the likelihood of attendance while providing hospital staff with real-time insights to better manage clinic schedules.

The pilot is expected to begin in late 2025 or early 2026, potentially expanding into a full €1.2 million contract.

The move forms part of Beaumont Hospital’s strategic plan through 2030 to reduce outpatient non-attendance. It follows the broader adoption of AI in Irish healthcare, including Mater Hospital’s recent launch of an AI and Digital Health centre designed to tackle clinical challenges using new technologies.

Instead of viewing AI as a future option, Irish hospitals now increasingly treat it as an immediate solution to operational inefficiencies, hoping it will transform healthcare delivery and improve patient service.

Quantum tech could break online security, warns India

The Indian Computer Emergency Response Team (CERT-In), alongside cybersecurity firm SISA, cautions that these powerful machines could soon break the encryption used to protect everything from online banking to personal identity systems.

CERT-In’s new white paper outlines how attackers may already be stockpiling encrypted data to unlock later using quantum tools, a tactic called ‘harvest now, decrypt later’. If left unaddressed, this strategy could expose sensitive data stored today once quantum technology matures.

AI is adding to the urgency. As it becomes more embedded in digital systems, it also increases access to user data, raising the stakes if encryption is compromised. The biggest digital systems in India, including Aadhaar, cryptocurrencies, and smart devices, are seen as particularly exposed to this looming risk.

Everyday users are advised to take precautions: update devices regularly, use strong passwords with multi-factor authentication, and avoid storing sensitive data online long-term. Services like Signal or ProtonMail, which use strong encryption, are also recommended.

Hackers hide malware using DNS TXT records

Hackers are increasingly exploiting DNS records to deliver malware undetected, according to new research from DomainTools.

Instead of relying on typical delivery methods such as emails or downloads, attackers now hide malicious code within DNS TXT records, part of the Domain Name System, often overlooked by security systems.

The method involves converting malware into hexadecimal code, splitting it into small segments, and storing each chunk in the TXT record of subdomains under domains like whitetreecollective.com.

Once attackers gain limited access to a network, they retrieve these chunks via ordinary-looking DNS queries, reassembling them into functioning malware without triggering antivirus or firewall alerts.

The rising use of encrypted DNS protocols like DNS-over-HTTPS and DNS-over-TLS makes detecting such queries harder, especially without in-house DNS resolvers equipped for deep inspection.

Researchers also noted that attackers are using DNS TXT records for malware and embedding harmful text designed to manipulate AI systems through prompt injection.

Ian Campbell of DomainTools warns that even organisations with strong security measures struggle to detect such DNS-based threats due to the hidden nature of the traffic.

Instead of focusing solely on traditional defences, organisations are advised to monitor DNS traffic closely, log and inspect queries through internal resolvers, and restrict DNS access to trusted sources. Educating teams on these emerging threats remains essential for maintaining robust cybersecurity.

Stay True To The Act campaign defends music rights

More than 30 European musicians have launched a united video campaign urging the European Commission to preserve the integrity of the EU AI Act.

The Stay True To The Act campaign calls on policymakers to enforce transparency and uphold copyright protections.

Artists, including Spanish singer-songwriter Álex Ubago and Poland’s Eurovision 2025 entrant Justyna Steczkowska, have voiced concern over the unauthorised use of their work to train AI models. They demand the right to be informed and the power to refuse such usage.

The EU AI Act, passed in 2024, includes provisions requiring developers to disclose the content used in AI training. However, as implementation plans develop, artists fear the law may be diluted, weakening protections for creators.

The campaign appeals for vigorous enforcement of the Act’s original principles: transparency, copyright control and fair innovation. Artists say AI and music can coexist in Europe only if ethical boundaries are upheld.
