Children’s screen time debate heats up as experts question evidence

A growing number of scientists are questioning whether fears over children’s screen time are truly backed by evidence. While many parents worry about smartphones, social media, and gaming, experts say the science behind these concerns is often flawed or inconsistent.

Professor Pete Etchells of Bath Spa University and other researchers argue that common claims about screen time harming adolescent brains or causing depression lack strong evidence.

Much of the existing research relies on self-reported data and fails to account for critical factors like loneliness or the type of screen engagement.

One major study found no link between screen use and poor mental wellbeing, while others stress the importance of distinguishing between harmful content and positive online interaction.

Still, many campaigners and psychologists maintain that screen restrictions are vital. Groups such as Smartphone Free Childhood are pushing to delay access to smartphones and social media.

Others, like Professor Jean Twenge, say the risks of screen overuse—less sleep, reduced social time, and more time alone—create a ‘terrible formula for mental health.’

With unclear guidance and evolving science, parents face tough choices in a rapidly changing tech world. As screens become more common via AI, smart glasses, and virtual communities, the focus shifts to how children can use technology wisely and safely.

Apple’s $20B Google deal under threat as AI lags behind rivals

Apple is set to release Q3 earnings on Thursday amid scrutiny over its Google search deal dependencies and ongoing struggles with AI progress.

Typically, Apple’s fiscal Q3 garners less investor attention, with anticipation focused instead on the upcoming iPhone launch in Q4. However, this quarter is proving to be anything but ordinary.

Analysts and shareholders alike are increasingly concerned about two looming threats: a potential $20 billion hit to Apple’s Services revenue tied to the US Department of Justice’s (DOJ) antitrust case against Google, and ongoing delays in Apple’s AI efforts.

Ahead of the earnings report, Apple shares were mostly unchanged, reflecting investor caution rather than enthusiasm. Apple’s most pressing challenge stems from its lucrative partnership with Google.

In 2022, Google paid Apple approximately $20 billion to remain the default search engine in the Safari browser and across Siri.

The exclusivity deal has formed a significant portion of Apple’s Services segment, which generated $78.1 billion in revenue that year, making Google’s contribution alone account for more than 25% of that figure.

However, a ruling expected next month from Judge Amit Mehta in the US District Court for the District of Columbia could threaten the entire arrangement. Mehta previously found Google guilty of operating an illegal monopoly in the search market.

The forthcoming ‘remedies’ ruling could force Google to end exclusive search deals, divest its Chrome browser, and provide data access to rivals. Should the DOJ’s proposed remedies stand and Google fails to overturn the ruling, Apple could lose a critical source of Services revenue.

According to Morgan Stanley’s Erik Woodring, Apple could see a 12% decline in its full-year 2027 earnings per share (EPS) if it pivots to less lucrative partnerships with alternative search engines.

The user experience may also deteriorate if customers can no longer set Google as their default option. A more radical scenario, Apple launching its search engine, could dent its 2024 EPS by as much as 20%, though analysts believe this outcome is the least likely.

Alongside regulatory threats, Apple is also facing growing doubts about its ability to compete in AI. Apple has not yet set a clear timeline for releasing an upgraded version of Siri, while rivals accelerate AI hiring and unveil new capabilities.

Bank of America analyst Wamsi Mohan noted this week that persistent delays undermine confidence in Apple’s ability to deliver innovation at the pace. ‘Apple’s ability to drive future growth depends on delivering new capabilities and products on time,’ he wrote to investors.

‘If deadlines keep slipping, that potentially delays revenue opportunities and gives competitors a larger window to attract customers.’

While Apple has teased upcoming AI features for future software updates, the lack of a commercial rollout or product roadmap has made investors uneasy, particularly as rivals like Microsoft, Google, and OpenAI continue to set the AI agenda.

Although Apple’s stock remained stable before Thursday’s earnings release, any indication of slowing services growth or missed AI milestones could shake investor confidence.

Analysts will be watching closely for commentary from CEO Tim Cook on how Apple plans to navigate regulatory risks and revive momentum in emerging technologies.

The company’s current crossroads is pivotal for the tech sector more broadly. Regulators are intensifying scrutiny on platform dominance, and AI innovation is fast becoming the new battleground for long-term growth.

As Apple attempts to defend its business model and rekindle its innovation edge, Thursday’s earnings update could serve as a bellwether for its direction in the post-iPhone era.

VPN dangers highlighted as UK’s Online Safety Act comes into force

Britons are being urged to proceed with caution before turning to virtual private networks (VPNs) in response to the new age verification requirements set by the Online Safety Act.

The law, now in effect, aims to protect young users by restricting access to adult and sensitive content unless users verify their age.

Instead of offering anonymous access, some platforms now demand personal details such as full names, email addresses, and even bank information to confirm a user’s age.

Although the legislation targets adult websites, many people have reported being blocked from accessing less controversial content, including alcohol-related forums and parts of Wikipedia.

As a result, more users are considering VPNs to bypass these checks. However, cybersecurity experts warn that many VPNs can pose serious risks by exposing users to scams, data theft, and malware. Without proper research, users might install software that compromises their privacy rather than protecting it.

With Ofcom reporting that eight per cent of children aged 8 to 14 in the UK have accessed adult content online, the new rules are viewed as a necessary safeguard. Still, concerns remain about the balance between online safety and digital privacy for adult users.

Australian companies unite cybersecurity defences to combat AI threats

Australian companies are increasingly adopting unified, cloud-based cybersecurity systems as AI reshapes both threats and defences.

A new report from global research firm ISG reveals that many enterprises are shifting away from fragmented, uncoordinated tools and instead opting for centralised platforms that can better detect and counter sophisticated AI-driven attacks.

The rapid rise of generative AI has introduced new risks, including deepfakes, voice cloning and misinformation campaigns targeting elections and public health.

In response, organisations are reinforcing identity protections and integrating AI into their security operations to improve both speed and efficiency. These tools also help offset a growing shortage of cybersecurity professionals.

After a rushed move to the cloud during the pandemic, many businesses retained outdated perimeter-focused security systems. Now, firms are switching to cloud-first strategies that target vulnerabilities at endpoints and prevent misconfigurations instead of relying on legacy solutions.

By reducing overlap in systems like identity management and threat detection, businesses are streamlining defences for better resilience.

ISG also notes a shift in how companies choose cybersecurity providers. Firms like IBM, PwC, Deloitte and Accenture are seen as leaders in the Australian market, while companies such as TCS and AC3 have been flagged as rising stars.

The report further highlights growing demands for compliance and data retention, signalling a broader national effort to enhance cyber readiness across industries.

Alignment Project to tackle safety risks of advanced AI systems

The UK’s Department for Science, Innovation and Technology (DSIT) has announced a new international research initiative aimed at ensuring future AI systems behave in ways aligned with human values and interests.

Called the Alignment Project, the initiative brings together global collaborators including the Canadian AI Safety Institute, Schmidt Sciences, Amazon Web Services (AWS), Anthropic, Halcyon Futures, the Safe AI Fund, UK Research and Innovation, and the Advanced Research and Invention Agency (ARIA).

DSIT confirmed that the project will invest £15 million into AI alignment research – a field concerned with developing systems that remain responsive to human oversight and follow intended goals as they become more advanced.

Officials said this reflects growing concerns that today’s control methods may fall short when applied to the next generation of AI systems, which are expected to be significantly more powerful and autonomous.

This positioning reinforces the urgency and motivation behind the funding initiative, before going into the mechanics of how the project will work.

The Alignment Project will provide funding through three streams, each tailored to support different aspects of the research landscape. Grants of up to £1 million will be made available for researchers across a range of disciplines, from computer science to cognitive psychology.

A second stream will provide access to cloud computing resources from AWS and Anthropic, enabling large-scale technical experiments in AI alignment and safety.

The third stream focuses on accelerating commercial solutions through venture capital investment, supporting start-ups that aim to build practical tools for keeping AI behaviour aligned with human values.

An expert advisory board will guide the distribution of funds and ensure that investments are strategically focused. DSIT also invited further collaboration, encouraging governments, philanthropists, and industry players to contribute additional research grants, computing power, or funding for promising start-ups.

Science, Innovation and Technology Secretary Peter Kyle said it was vital that alignment research keeps pace with the rapid development of advanced systems.

‘Advanced AI systems are already exceeding human performance in some areas, so it’s crucial we’re driving forward research to ensure this transformative technology is behaving in our interests,’ Kyle said.

‘AI alignment is all geared towards making systems behave as we want them to, so they are always acting in our best interests.’

The announcement follows recent warnings from scientists and policy leaders about the risks posed by misaligned AI systems. Experts argue that without proper safeguards, powerful AI could behave unpredictably or act in ways beyond human control.

Geoffrey Irving, chief scientist at the AI Safety Institute, welcomed the UK’s initiative and highlighted the need for urgent progress.

‘AI alignment is one of the most urgent and under-resourced challenges of our time. Progress is essential, but it’s not happening fast enough relative to the rapid pace of AI development,’ he said.

‘Misaligned, highly capable systems could act in ways beyond our ability to control, with profound global implications.’

He praised the Alignment Project for its focus on international coordination and cross-sector involvement, which he said were essential for meaningful progress.

‘The Alignment Project tackles this head-on by bringing together governments, industry, philanthropists, VC, and researchers to close the critical gaps in alignment research,’ Irving added.

‘International coordination isn’t just valuable – it’s necessary. By providing funding, computing resources, and interdisciplinary collaboration to bring more ideas to bear on the problem, we hope to increase the chance that transformative AI systems serve humanity reliably, safely, and in ways we can trust.’

The project positions the UK as a key player in global efforts to ensure that AI systems remain accountable, transparent, and aligned with human intent as their capabilities expand.

White House launches AI Action Plan with Executive Orders on exports and regulation

The White House has unveiled a sweeping AI strategy through its new publication Winning the Race: America’s AI Action Plan.

Released alongside three Executive Orders, the plan outlines the federal government’s next phase in shaping AI policy, focusing on innovation, infrastructure, and global leadership.

The AI Action Plan centres on three key pillars: accelerating AI development, establishing national AI infrastructure, and promoting American AI standards globally. Four consistent themes run through each pillar: regulation and deregulation, investment, research and standardisation, and cybersecurity.

Notably, deregulation is central to the plan’s strategy, particularly in reducing barriers to AI growth and speeding up infrastructure approval for data centres and grid expansion.

Investment plays a dominant role. Federal funds will support AI job training, data access, lab automation, and domestic component manufacturing, instead of relying on foreign suppliers.

Alongside, the plan calls for new national standards, improved dataset quality, and stronger evaluation mechanisms for AI interpretability, control, and safety. A dedicated AI Workforce Research Hub is also proposed.

In parallel, three Executive Orders were issued. One bans ‘woke’ or ideologically biased AI tools in federal use, another fast-tracks data centre development using federal land and brownfield sites, and a third launches an AI exports programme to support full-stack US AI systems globally.

While these moves open new opportunities, they also raise questions around regulation, bias, and the future shape of AI development in the US.

ChatGPT gets smarter with Study Mode to support active learning

OpenAI has launched a new Study Mode in ChatGPT to help users engage more deeply with learning. Rather than simply providing answers, the feature guides users through concepts and problem-solving step-by-step. It is designed to support critical thinking and improve long-term understanding.

The company developed the feature with educators, scientists, and pedagogy experts. They aimed to ensure the AI supports active learning and doesn’t just deliver quick fixes. The result is a mode that encourages curiosity, reflection, and metacognitive development.

According to OpenAI, Study Mode allows users to approach subjects more critically and thoroughly. It breaks down complex ideas, asks questions, and helps manage cognitive load during study. Instead of spoon-feeding, the AI acts more like a tutor than a search engine.

The shift reflects a broader trend in educational technology — away from passive learning tools. Many students turn to AI for homework help, but educators have warned of over-reliance. Study Mode attempts to strike a balance by promoting engagement over shortcuts.

For instance, rather than giving the complete solution to a maths problem, Study Mode might ask: ‘What formula might apply here?’ or ‘How could you simplify this expression first?’ This approach nudges students to participate in the process and build fundamental problem-solving skills.

It also adapts to different learning needs. In science, it might walk through hypotheses and reasoning. It may help analyse a passage or structure an essay in the humanities. Prompting users to think aloud mirrors effective tutoring strategies.

OpenAI says feedback from teachers helped shape the feature’s tone and pacing. One key aim was to avoid overwhelming learners with too much information at once. Instead, Study Mode introduces concepts incrementally, supporting better retention and understanding.

The company also consulted cognitive scientists to align with best practices in memory and comprehension. However, this includes encouraging users to reflect on their learning and why specific steps matter. Such strategies are known to improve both academic performance and self-directed learning.

While the feature is part of ChatGPT, it can be toggled on or off. Users can activate Study Mode when tackling a tricky topic or exploring new material. They can then switch to normal responses for broader queries or summarised answers.

Educators have expressed cautious optimism about the update. Some see it as a tool supporting homework, revision, or assessment preparation. However, they also warn that no AI can replace direct teaching or personalised guidance.

Tools like this could be valuable in under-resourced settings or for independent learners.

Study Mode’s interactive style may help level the playing field for students without regular academic support. It also gives parents and tutors a new way to guide learners without doing the work for them.

Earlier efforts included teacher guides and classroom use cases. However, Study Mode marks a more direct push to reshape how students use AI in learning.

It positions ChatGPT not as a cheat sheet, but as a co-pilot for intellectual growth.

Looking ahead, OpenAI says it plans to iterate based on user feedback and teacher insights. Future updates may include subject-specific prompts, progress tracking, or integrations with educational platforms. The goal is to build a tool that adapts to learning styles without compromising depth or rigour.

As AI continues to reshape education, tools like Study Mode may help answer a central question: Can technology support genuine understanding, instead of just faster answers? With Study Mode, OpenAI believes the answer is yes, if used wisely.

NATO highlights cyber vulnerabilities in European ports

A recent policy brief from NATO’s Cooperative Cyber Defence Centre of Excellence (CCDCOE) indicates that Europe’s civilian ports, which handle approximately 80% of international trade and support NATO logistics, are increasingly targeted by cyberattacks linked to state-affiliated actors. The report identifies a rise in disruptions affecting port access control systems and vessel traffic management across various countries, with suspected involvement from groups associated with Russia, Iran, and China.

The document notes that NATO’s current maritime strategy lacks formal mechanisms to engage with commercial port operators, who manage critical infrastructure exposed to cyber threats. It calls for updated strategic frameworks to improve coordination between civil and military sectors, and to enhance cybersecurity and resilience across digital, operational, and energy systems in ports.

The brief outlines common attack methods, such as denial-of-service, phishing, ransomware, and malware, which have affected numerous maritime organisations in 2024.

Key recommendations include:

  • Updating NATO’s 2011 maritime strategy to integrate cybersecurity and establish engagement channels with commercial port operators.
  • Establishing sector-specific intelligence-sharing frameworks to support timely incident response.
  • Developing coordinated public–private action plans and resilience measures at both national and alliance levels.

Survey finds developers value AI for ideas, not final answers

As AI becomes more integrated into developer workflows, a new report shows that trust in AI-generated results erodes. According to Stack Overflow’s 2025 Developer Survey, the use of AI has increased to 84%, up from 76% last year. However, trust in its output has dropped, especially among experienced professionals.

The survey found that 46% of developers now lack trust in AI-generated answers.

That figure marks a sharp increase from 31% in 2024, suggesting growing scepticism despite higher adoption. By contrast, only 3.1% of developers trust AI responses.

Interestingly, trust varies with experience. Beginners were twice as likely to express high confidence in AI, with 6.1% reporting strong trust, compared with just 2.5% among seasoned developers. The results indicate a divide in how AI is perceived across the developer landscape.

Despite doubts, developers continue to use AI tools across various tasks. The vast majority – 78.5% – use AI on an infrequent basis, such as once a month. The pattern holds across experience levels, suggesting cautious and situational usage.

While trust is lacking, developers still see AI as a helpful starting point. Three in five respondents reported favourable views of AI tools overall. One in five viewed them negatively, with the remaining 20% remaining neutral.

However, that usefulness has limits. Developers were quick to seek human input when unsure about AI responses. Seventy-five percent said they would ask someone when they didn’t trust an AI-generated answer. Fifty-eight percent preferred human advice when they didn’t fully understand a solution.

Ethics and security were also areas where developers preferred human judgement. Again, 58% reported turning to colleagues or mentors to evaluate such risks. Such cases show a continued reliance on human expertise in high-stakes decisions.

Stack Overflow CEO Prashanth Chandrasekar acknowledged the limitations of AI in the development process. ‘AI is a powerful tool, but it has significant risks of misinformation or can lack complexity or relevance,’ he said. He added that AI best uses a ‘trusted human intelligence layer’.

The data also revealed that developers may not trust AI entirely but use it to support learning.

Forty-four percent of respondents admitted using AI tools to learn how to code, up from 37% last year.

A further 36% use it for work-related growth or career advancement.

The results highlight the role of AI as an educational companion rather than a coding authority.

It can help users understand concepts or generate basic examples, but most still want human review.

That distinction matters as teams consider how to integrate AI into production workflows.

Some developers are concerned that overreliance on AI could reduce the depth of their problem-solving skills. Others worry about hallucinations — AI-generated content that appears accurate but is misleading or incorrect. Such risks have led to a cautious, layered approach to using AI tools in real-life projects.

Stack Overflow’s findings align with broader AI adoption and trust industry trends. Tech firms are exploring ways to integrate AI safely, but many prioritise transparency and human oversight. Chandrasekar believes developers are uniquely positioned to help shape AI’s future revolution.

‘By providing a trusted human intelligence layer in the age of AI, we believe the tech enthusiasts of today can play a larger role in adding value,’ he said. ‘They’ll help build the AI technologies and products of tomorrow.’

As AI continues to expand into software development, one thing is clear: trust matters. Developers are open to using AI – but only when it supports, rather than replaces, human judgement. The challenge now is building systems that earn and maintain that trust.
