NVIDIA introduces infrastructure-level security model for autonomous AI agents

OpenShell, an open-source runtime introduced by NVIDIA, is designed to support the secure deployment of autonomous AI agents within enterprise environments.

According to NVIDIA, OpenShell applies security controls at the infrastructure level rather than within the model or application layer. The runtime ensures that each agent operates inside an isolated sandbox, where system-level policies define and enforce permissions, resource access, and operational constraints.

The company states that such an approach separates agent behaviour from policy enforcement, preventing agents from overriding security controls or accessing restricted data.

OpenShell enables organisations to define and monitor a unified policy layer governing how autonomous systems interact with files, tools, and enterprise workflows.

Additionally, OpenShell forms part of the NVIDIA Agent Toolkit and is complemented by NemoClaw, a reference stack designed to support the deployment of continuously operating AI assistants.

NVIDIA indicates that the system can run across cloud, on-premises, and local computing environments, while maintaining consistent policy enforcement.

The company also reports collaboration with industry partners, including Cisco, CrowdStrike, Google Cloud, and Microsoft Security, to align security practices for AI agent deployment. Both OpenShell and NemoClaw are currently in early preview.

UK pushes platforms to tackle AI abuse and online violence against women

The Department for Science, Innovation and Technology has called on online service providers to strengthen measures against digital harms targeting women and girls, as part of a commitment to halve such violence within a decade.

In a letter published on 23 March 2026, Liz Kendall outlined expectations for platforms operating under the Online Safety Act.

The letter states that the government has strengthened criminal law and regulatory frameworks, including new offences related to harmful pornographic practices and intimate image abuse.

It confirms that sharing or threatening to share sexually explicit deepfakes without consent constitutes a criminal offence, while the non-consensual creation of such content has also been criminalised and is being designated as a priority offence under the Act.

Further measures include amendments to the Crime and Policing Bill to ban so-called ‘nudification’ tools and extend illegal content duties to AI chatbots.

The government is also introducing a requirement for platforms to remove non-consensual intimate images within 48 hours, with a focus on reducing repeated reporting burdens for victims.

The Secretary of State urged companies to implement recommendations from Ofcom’s guidance on online safety for women and girls, including risk assessments, stronger privacy settings, and limits on the visibility of harmful content.

Platforms are expected to comply by the end of the year, with progress to be monitored.

Pinterest chief calls for stricter youth rules

The chief executive of Pinterest has voiced support for governments banning access to social media for people under 16. He cited rising concerns about mental health, screen addiction and online harms among young users.

He praised the Australian decision to ban social media for under-16s and urged other nations to adopt similar protections. He argued that existing tech safety measures have fallen short of keeping children secure online.

The executive warned that AI enhancements in social platforms may amplify behavioural influence on teens. He compared the inaction by tech companies to past resistance by harmful industries to public health safeguards.

He also highlighted surveys showing parental worries about explicit content and excessive screen time. Pinterest’s view supports calls for clear age limits, better tools for parents and stronger platform accountability.

AI improves stroke care and reduces patient risks in major study

The system, which analyses medical scans and provides treatment recommendations, was associated with better outcomes compared with standard approaches to stroke care. Researchers said the tool offers a more efficient and scalable method for improving treatment, particularly in resource-constrained healthcare systems.

The findings are based on more than 21,000 patients treated across 77 hospitals in China. Patients supported by the AI-driven clinical decision support system experienced fewer new vascular events, including stroke recurrence, heart attack, or related death, over follow-up periods of up to 12 months.

At three months, new vascular events occurred in 2.9% of patients using the system, compared with 3.9% in those receiving usual care, representing a 26% reduction. The benefit persisted at 12 months, with rates of 4% in the intervention group versus 5.5% in the control group.

Patients receiving AI-supported treatment also showed improved performance on key stroke care quality measures, although no significant differences were observed in disability, mortality, or bleeding outcomes between the groups.

Researchers noted limitations, including the study design, which randomised hospitals rather than individual patients, and potential differences in follow-up care. However, they highlighted the system’s ease of integration into hospital workflows and its potential to strengthen stroke care delivery and long-term prevention strategies.

Deepfakes scandal puts Elon Musk and X under scrutiny in France

French prosecutors have escalated concerns about deepfakes linked to Elon Musk’s platform X, alerting US authorities to suspicions that manipulated content may have been used to influence the company’s valuation.

According to the Paris prosecutor’s office, the controversy surrounding sexually explicit deepfakes generated by Grok, X’s AI tool, may have been deliberately amplified to artificially boost the value of X and its associated AI entity ahead of a planned stock market listing in June 2026.

Authorities in France confirmed they had contacted the US Department of Justice and legal representatives at the Securities and Exchange Commission to share findings related to the deepfakes investigation and potential financial implications.

The case builds on an ongoing French probe into X, which initially focused on alleged algorithmic interference in domestic politics. Investigations have since expanded to include the spread of Holocaust denial content and the dissemination of sexualised deepfakes through Grok.

French regulators have taken additional steps, including summoning Musk for a voluntary interview and conducting searches at X’s local offices, actions he has described as politically motivated. Parallel investigations have also been launched in the UK and across the European Union into the use of AI tools to generate harmful deepfakes involving women and minors.

Social media ban in Ecuador targets youth crime recruitment

A proposal to restrict minors’ online activity is gaining momentum in Ecuador, where lawmakers are considering a social media ban for children under 15 as part of a broader response to rising organised crime.

Under discussion in the National Assembly, the initiative introduced by Assembly member Katherine Pacheco Machuca would amend the Code of Childhood and Adolescence to block access to platforms enabling public interaction, content sharing, and messaging. The proposal defines social networks broadly, covering services that allow users to create accounts, connect with others, and exchange content.

Unlike similar debates elsewhere, the justification for the social media ban is rooted less in mental health or privacy concerns and more in security. Ecuador has experienced a sharp deterioration in public safety, with rising homicide rates, expanding criminal networks, and increasing pressure on state institutions.

Recent findings from Ecuador’s Organised Crime Observatory indicate that around 27% of minors approached by criminal groups report initial contact through social media platforms. Surveys conducted by ChildFund Ecuador further suggest that vulnerable adolescents are increasingly exposed to recruitment tactics that combine economic incentives with normalised portrayals of violence.

In that context, the proposed social media ban is framed as a preventative measure against criminal recruitment rather than solely a child protection tool. The initiative forms part of a wider regulatory shift, including new cybersecurity legislation and draft laws targeting recruitment practices conducted through digital channels.

Social media linked to declining well-being among young people

The World Happiness Report 2026 has identified a growing decline in well-being among young people, with increased social media use emerging as a key contributing factor. These findings suggest that digital habits are increasingly shaping life satisfaction, particularly across Western societies.

The report notes that younger age groups now report significantly lower happiness levels compared to previous decades.

In regions such as North America and Western Europe, the decline coincides with a sharp rise in time spent on social media platforms. Researchers highlight that heavy usage is associated with measurable reductions in well-being, especially among younger users.

Alongside these trends, the report continues to rank Finland as the happiest country globally, reflecting broader stability in Nordic nations. However, such stability contrasts with emerging concerns about mental health and social outcomes in more industrialised regions, where digital environments are playing an increasingly influential role.

While the report identifies risks including cyberbullying, depression and online exploitation, it does not advocate for complete restrictions. Instead, it emphasises the need for carefully designed regulatory approaches that balance protection with the potential benefits of digital connectivity.

Human data demand fuels new global digital economy

A growing number of individuals worldwide are participating in a new digital economy built around supplying data for AI systems.

Through platforms such as Kled AI and Silencio, users upload videos, audio recordings and personal interactions in exchange for payment, contributing to the development of increasingly sophisticated AI models.

Such a trend reflects a broader shift in the AI industry, where demand for high-quality human-generated data is rising as traditional web-based sources become more limited.

Researchers suggest that human data remains essential for improving system performance and modelling behaviour beyond existing datasets. As a result, data marketplaces have emerged as an alternative supply mechanism.

Economic considerations often shape participation. In regions facing limited employment opportunities or currency instability, earning income in global currencies can provide a meaningful financial incentive.

At the same time, similar practices are expanding in higher-income countries, where individuals seek supplementary income streams amid rising living costs.

However, the model introduces complex trade-offs.

Contributors may grant extensive usage rights over their data, sometimes on a long-term or irreversible basis. Experts note that such arrangements can reduce control over how personal information is reused, including in contexts not initially anticipated.

Concerns also extend to issues such as data security, transparency and the potential for misuse in areas including synthetic media and identity replication.
