ByteDance cuts use of Claude after Anthropic blocks China access

An escalating tech clash has emerged between ByteDance and Anthropic over AI access and service restrictions. ByteDance has halted use of Anthropic’s Claude model on its infrastructure after the US firm imposed access limitations for Chinese users.

The suspension follows Anthropic’s move to restrict China-linked deployments and aligns with broader geopolitical tensions in the AI sector. ByteDance reportedly said it would now rely on domestic alternatives, signalling a strategic pivot away from western-based AI models.

Industry watchers view the dispute as a marker of how major tech firms are navigating export controls, national security concerns and sovereignty in AI. Observers warn the rift may prompt accelerated investment in home-grown AI ecosystems by Chinese companies.

While neither company has detailed all operational impacts, the episode highlights AI’s fraught position at the intersection of technology and geopolitics. US market reaction may hinge on whether other firms follow suit or partnerships are redefined around regional access.

AI tool on smartwatch detects hidden structural heart disease

An AI algorithm paired with smartwatch sensors has successfully detected structural heart diseases, including valve damage and weakened heart muscles, in adults. The study, conducted at Yale School of Medicine, will be presented at the American Heart Association’s 2025 Scientific Sessions in New Orleans.

The AI model was trained on over 266,000 electrocardiogram recordings and validated across multiple hospitals and population studies. When tested on 600 participants using single-lead ECGs from a smartwatch, it achieved an 88% accuracy in detecting heart disease.

Researchers said smartwatches could offer a low-cost, accessible method for early screening of structural heart conditions that usually require echocardiograms. The algorithm’s ability to analyse single-lead ECG data could enable preventive detection before symptoms appear.

Experts emphasised that smartwatch data cannot replace medical imaging, but it could complement clinical assessments and expand access to screening. Larger studies in the US are planned to confirm effectiveness and explore community-based use in preventive heart care.

NYPD sued over Microsoft-linked surveillance system

The New York Police Department is facing a lawsuit from the Surveillance Technology Oversight Project (S.T.O.P.), which accuses it of running an invasive citywide surveillance network built with Microsoft technology.

The system, known as the Domain Awareness System (DAS), has operated since 2012 and connects more than a dozen surveillance tools, including video cameras, biometric scanners, license plate readers, and financial analytics, into one centralised network. According to court filings, the system collects location data, social media activity, vehicle information, and even banking details to create ‘digital profiles’ of millions of residents.

S.T.O.P. argues that the network captures and stores data on all New Yorkers, including those never suspected of a crime, amounting to a ‘web of surveillance’ that violates constitutional rights. The group says newly obtained records show that DAS integrates citywide cameras, 911 and 311 call logs, police databases, and feeds from drones and helicopters into a single monitoring platform.

Calling DAS ‘an unprecedented violation of American life’, the organisation has asked the US District Court for the Southern District of New York to declare the city’s surveillance practices unconstitutional.

This is not the first time Microsoft’s technology has drawn scrutiny this year over data tracking and storing, its recently announced ‘Recall’ feature also raised alarm over potential privacy issues.

Experts caution that AI growth could double data centre energy use

AI’s rapid growth is fuelling a surge in electricity consumption across the United States, with data centres emerging as major contributors. Analysts warn that expanding AI infrastructure is pushing up national energy demand and could drive higher electricity bills for homes and businesses.

The US hosts more than 4,000 data centres, concentrated mainly in Virginia, Texas and California. Many now operate high-performance AI systems that consume up to 30 times more electricity than traditional facilities, according to energy experts.

The International Energy Agency reported that US data centres used a record 183 terawatt-hours of electricity in 2024, about 4% of national demand. That figure could more than double by 2030, reaching 426 terawatt-hours, as companies race to expand cloud and AI capacity.

With 60% of energy use tied to servers and processing hardware, the shift toward AI-driven computing poses growing challenges for green energy infrastructure. Researchers say that without major efficiency gains, the nation’s power grid will struggle to keep pace with AI’s accelerating appetite for electricity.

US Internet Bill of Rights unveiled as response to global safety laws

A proposed US Internet Bill of Rights aims to protect digital freedoms as governments expand online censorship laws. The framework, developed by privacy advocates, calls for stronger guarantees of free expression, privacy, and access to information in the digital era.

Supporters argue that recent legislation such as the UK’s Online Safety Act, the EU’s Digital Services Act, and US proposals like KOSA and the STOP HATE Act have eroded civil liberties. They claim these measures empower governments and private firms to control online speech under the guise of safety.

The proposed US bill sets out rights including privacy in digital communications, platform transparency, protection against government surveillance, and fair access to the internet. It also calls for judicial oversight of censorship requests, open algorithms, and the protection of anonymous speech.

Advocates say the framework would enshrine digital freedoms through federal law or constitutional amendment, ensuring equal access and privacy worldwide. They argue that safeguarding free and open internet access is vital to preserve democracy and innovation.

Big Tech ramps up Brussels lobbying as EU considers easing digital rules

Tech firms now spend a record €151 million a year on lobbying at EU institutions, up from €113 million in 2023, according to transparency-register analysis by Corporate Europe Observatory and LobbyControl.

Spending is concentrated among US giants. The ten biggest tech companies, including Meta, Microsoft, Apple, Amazon, Qualcomm and Google, together outspend the top ten in pharma, finance and automotive. Meta leads with a budget above €10 million.

Estimates calculate there are 890 full-time lobbyists now working to influence tech policy in Brussels, up from 699 in 2023, with 437 holding European Parliament access badges. In the first half of 2025, companies declared 146 meetings with the Commission and 232 with MEPs, with artificial intelligence regulation and the industry code of practice frequently on the agenda.

As industry pushes back on the Digital Markets Act and Digital Services Act and the Commission explores the ‘simplification’ of EU rulebooks, lobbying transparency campaigners fear a rollback on the progress made to regulate the digital sector. On the contrary, companies argue that lobbying helps lawmakers grasp complex markets and assess impacts on innovation and competitiveness.

French lawmakers advance plan to double digital services tax on Big Tech

France’s National Assembly has voted to raise its digital services tax on major tech firms such as Google, Apple, Meta and Amazon from 3% to 6%, despite government warnings that the move could trigger US trade retaliation.

Economy Minister Roland Lescure said the increase would be ‘disproportionate’, cautioning that it could invite equally strong countermeasures from Washington. Lawmakers had initially proposed a 15% levy in response to former US President Donald Trump’s tariff threats, but scaled back amid opposition from industry and the government.

The amendment still requires final approval in next week’s budget vote and then in the French Senate. The proposal also raises the global revenue threshold for companies subject to the digital services tax from €750 million to €2 billion, aiming to shield smaller domestic firms.

John Murphy of the US Chamber of Commerce criticised the plan, arguing it solely targets American companies. Lawmaker Charles Sitzenstuhl, from President Emmanuel Macron’s party, stressed that ‘the objective of this tax was not to harm the United States in any way’, addressing US officials following the vote.

FDA and patent law create dual hurdles for AI-enabled medical technologies

AI reshapes healthcare by powering more precise and adaptive medical devices and diagnostic systems.

Yet, innovators face two significant challenges: navigating the US Food and Drug Administration’s evolving regulatory framework and overcoming legal uncertainty under US patent law.

These two systems, although interconnected, serve different goals. The FDA protects patients, while patent law rewards invention.

The FDA’s latest guidance seeks to adapt oversight for AI-enabled medical technologies that change over time. Its framework for predetermined change control plans allows developers to update AI models without resubmitting complete applications, provided updates stay within approved limits.

An approach that promotes innovation while maintaining transparency, bias control and post-market safety. By clarifying how adaptive AI devices can evolve safely, the FDA aims to balance accountability with progress.

Patent protection remains more complex. US courts continue to exclude non-human inventors, creating tension when AI contributes to discoveries.

Legal precedents such as Thaler vs Vidal and Alice Corp. vs CLS Bank limit patent eligibility for algorithms or diagnostic methods that resemble abstract ideas or natural laws. Companies must show human-led innovation and technical improvement beyond routine computation to secure patents.

Aligning regulatory and intellectual property strategies is now essential. Developers who engage regulators early, design flexible change control plans and coordinate patent claims with development timelines can reduce risk and accelerate market entry.

Integrating these processes helps ensure AI technologies in healthcare advance safely while preserving inventors’ rights and innovation incentives.
