Energy efficiency becomes a priority as Nvidia unveils next AI chip

Nvidia used CES in Las Vegas to signal its next push in AI hardware, with chief executive Jensen Huang unveiling a new AI chip designed to deliver more computing power with lower energy use. The chip, named Vera Rubin, is scheduled to ship in the second half of the year.

Huang said the Rubin platform would let companies train AI models with far fewer chips than earlier generations. The redesign is also intended to lower the cost and energy demands of running AI services.

The move comes as demand for AI infrastructure accelerates, straining power supplies and intensifying competition. Rivals and major customers developing their own chips are putting pressure on Nvidia to improve efficiency.

Alongside chips, Nvidia highlighted its growing focus on autonomous vehicles. The company said new AI software would support self-driving development for carmakers and mobility firms, with vehicles using the chipmaker’s technology expected to ship later this year.

Huang said AI, robotics, and autonomy are central to the company’s long-term strategy, as the company seeks to expand beyond data centres. Rising competition and geopolitical scrutiny remain challenges, but Nvidia is betting that more efficient chips will keep it at the centre of the AI boom.

CES 2026 shows AMD betting on on-device AI at scale

AMD used CES 2026 to position AI as a default feature of personal and commercial computing. The company said AI is no longer limited to premium systems. Instead, it is being built directly into processors for consumer PCs, business laptops, compact desktops, and embedded platforms.

Executives described the shift as a new phase in AI adoption. CEO Lisa Su said usage has grown from early experimentation to more than one billion active users worldwide. Senior vice president Jack Huynh added that AI is redefining the PC by embedding intelligence, performance, and efficiency across devices.

The strategy centres on the Ryzen AI 400 Series and Ryzen AI PRO 400 Series processors. These chips integrate neural processing units delivering up to 60 TOPS of local AI compute. Built on Zen 5 architecture and XDNA 2 NPUs, they target Copilot+ PCs and enterprise deployments.

AMD also expanded its Ryzen AI Max+ portfolio for ultra-thin laptops, mini-PCs, and small workstations. The processors combine CPU, GPU, and NPU resources in a unified memory design. Desktop users saw the launch of the Ryzen 7 9850X3D, while developers were offered the Ryzen AI Halo platform.

Beyond PCs, AMD introduced a new Ryzen AI Embedded processor lineup for edge deployments. The chips are aimed at vehicles, factories, and autonomous systems. AMD said single-chip designs will support real-time AI workloads in robotics, digital twins, smart cameras, and industrial automation.

California launches DROP tool to erase data broker records

Residents in California now have a simpler way to force data brokers to delete their personal information.

The state has launched the Delete Requests and Opt-Out Platform, known as DROP, allowing residents to submit one verified deletion request that applies to every registered data broker instead of contacting each company individually.

A system that follows the Delete Act, passed in 2023, and is intended to create a single control point for consumer data removal.

Once a resident submits a request, the data brokers must begin processing it from August 2026 and will have 90 days to act. If data is not deleted, residents may need to provide extra identifying details.

First-party data collected directly by companies can still be retained, while data from public records, such as voter rolls, remains exempt. Highly sensitive data may fall under separate legal protections such as HIPAA.

The California Privacy Protection Agency argues that broader data deletion could reduce identity theft, AI-driven impersonation, fraud risk and unwanted marketing contact.

Penalties for non-compliance include daily fines for brokers who fail to register or ignore deletion orders. The state hopes the tool will make data rights meaningful instead of purely theoretical.

A launch that comes as regulators worldwide examine how personal data is used, traded and exploited.

California is positioning itself as a leader in consumer privacy enforcement, while questions continue about how effectively DROP will operate when the deadline arrives in 2026.

Cloud and AI growth fuels EU push for greener data centres

Europe’s growing demand for cloud and AI services is driving a rapid expansion of data centres across the EU.

Policymakers now face the difficulty of supporting digital growth instead of undermining climate targets, yet reliable sustainability data remains scarce.

Operators are required to report on energy consumption, water usage, renewable sourcing and heat reuse, but only around one-third have submitted complete data so far.

Brussels plans to introduce a rating scheme from 2026 that grades data centres on environmental performance, potentially rewarding the most sustainable new facilities with faster approvals under the upcoming Cloud and AI Development Act.

Industry groups want the rules adjusted so operators using excess server heat to warm nearby homes are not penalised. Experts also argue that stronger auditing and stricter application of standards are essential so reported data becomes more transparent and credible.

Smaller data centres remain largely untracked even though they are often less efficient, while colocation facilities complicate oversight because customers manage their own servers. Idle machines also waste vast amounts of energy yet remain largely unmeasured.

Meanwhile, replacing old hardware may improve efficiency but comes with its own environmental cost.

Even if future centres run on cleaner power and reuse heat, the manufacturing footprint of the equipment inside them remains a major unanswered sustainability challenge.

Policymakers say better reporting is essential if the EU is to balance digital expansion with climate responsibility rather than allowing environmental blind spots to grow.

AI tool helps find new treatments for heart disease

A new ΑΙ system developed at Imperial College London could accelerate the discovery of treatments for heart disease by combining detailed heart scans with huge medical databases.

Cardiovascular disease remains the leading cause of death across the EU, accounting for around 1.7 million deaths every year, so researchers believe smarter tools are urgently needed.

The AI model, known as CardioKG, uses imaging data from thousands of UK Biobank participants, including people with heart failure, heart attacks and atrial fibrillation, alongside healthy volunteers.

By linking information about genes, medicines and disease, the system aims to predict which drugs might work best for particular heart conditions instead of relying only on traditional trial-and-error approaches.

Among the medicines highlighted were methotrexate, normally used for rheumatoid arthritis, and diabetes drugs known as gliptins, which the AI suggested could support some heart patients.

The model also pointed to a possible protective effect from caffeine among people with atrial fibrillation, although researchers warned that individuals should not change their caffeine intake based on the findings alone.

Scientists say the same technology could be applied to other health problems, including brain disorders and obesity.

Work is already under way to turn the knowledge graph into a patient-centred system that follows real disease pathways, with the long-term goal of enabling more personalised and better-timed treatment.

Musk says users are liable for the illegal Grok content

Scrutiny has intensified around X after its Grok chatbot was found generating non-consensual explicit images when prompted by users.

Grok had been positioned as a creative AI assistant, yet regulators reacted swiftly once altered photos were linked to content involving minors. Governments and rights groups renewed pressure on platforms to prevent abusive use of generative AI.

India’s Ministry of Electronics and IT issued a notice to X demanding an Action Taken Report within 72 hours, citing failure to restrict unlawful content.

Authorities in France referred similar cases to prosecutors and urged enforcement under the EU’s Digital Services Act, signalling growing international resolve to control AI misuse.

Elon Musk responded by stating users, instead of Grok, would be legally responsible for illegal material generated through prompts. The company said offenders would face permanent bans and cooperation with law enforcement.

Critics argue that transferring liability to users does not remove the platform’s duty to embed stronger safeguards.

Independent reports suggest Grok has previously been involved in deepfake creation, creating a wider debate about accountability in the AI sector. The outcome could shape expectations worldwide regarding how platforms design and police powerful AI tools.

Plaud unveils compact AI NotePin S and new meeting app

Hardware maker Plaud has introduced a new AI notetaking pin called the Plaud NotePin S alongside a Mac desktop app for digital meeting notes ahead of CES in Las Vegas.

The wearable device costs 179 dollars and arrives with several accessories so users can attach or wear it in different ways. A physical button allows quick control of recordings and can be tapped to highlight key moments during conversations.

The NotePin S keeps the same core specifications as the earlier model, including 64GB of storage and up to 20 hours of continuous recording.

Two MEMS microphones capture speech clearly within roughly three metres. Owners receive 300 minutes of transcription each month without extra cost. Apple Find My support is also included, so users can locate the device easily instead of worrying about misplacing it.

Compared with the larger Note Pro, the new pin offers a shorter recording range and battery life, but the small size makes it easier to wear while travelling or working on the go.

Plaud says the device suits users who rely on frequent in-person conversations rather than long seated meetings.

Plaud has now sold more than 1.5 million notetaking devices. The company also aims to enter the AI meeting assistant market with a Mac desktop client that detects when a meeting is active and prompts users to capture audio.

The software records system sound and uses AI to organise the transcript into structured notes. Users can also add typed notes and images instead of relying only on audio.

Reddit overtakes TikTok in the UK social media race

In the UK, Reddit has quietly overtaken TikTok to become Britain’s fourth most-visited social media platform, marking a major shift in how people search for information and share opinions online.

Use of the platform among UK internet users has risen sharply over the past two years, driven strongly by younger audiences who are increasingly drawn to open discussion instead of polished influencer content.

Google’s algorithm changes have helped accelerate Reddit’s rise by prioritising forum-based conversations in search results. Partnership deals with major AI companies have reinforced visibility further, as AI tools increasingly cite Reddit threads.

Younger users in the UK appear to value unfiltered and experience-based conversations, creating strong growth across lifestyle, beauty, parenting and relationship communities, alongside major expansion in football-related discussion.

Women now make up more than half of Reddit’s UK audience, signalling a major demographic shift for a platform once associated mainly with male users. Government departments, including ministers, are also using Reddit for direct engagement through public Q&A sessions.

Tension remains part of the platform’s culture, yet company leaders argue that community moderation and voting systems help manage behaviour.

Reddit is now encouraging users to visit directly instead of arriving via search or AI summaries, positioning the platform as a human alternative to automated answers.

Texas project puts Fermi at centre of nuclear AI push

A large energy and AI campus is taking shape outside Amarillo, Texas, as startup Fermi America plans to build what it says would be the world’s largest private power grid. The project aims to support large-scale AI training using nuclear, gas, and solar power.

Known as Project Matador, the development would host millions of square metres of data centres and generate more electricity than many US states consume at peak demand. The site is near the Pantex nuclear weapons facility and is part of a broader push for US energy and AI dominance.

Fermi is led by former Texas governor and energy secretary Rick Perry alongside investor Toby Neugebauer. The company plans to deploy next-generation nuclear reactors and offer off-grid computing infrastructure, though it has yet to secure a confirmed anchor tenant.

The scale and cost of the project have raised questions among analysts and local residents. Critics point to financing risks, water use, and the challenge of delivering nuclear reactors on time and within budget, while supporters argue the campus could drive economic growth and national security benefits.

Backed by political momentum and rising demand for AI infrastructure, Fermi is pressing ahead with construction and partnerships. Whether Project Matador can translate ambition into delivery remains a key test as competition intensifies in the global race to power next-generation AI systems.
