AI-generated child sexual abuse videos surging online, watchdog says

The number of videos online of child sexual abuse generated by artificial intelligence has surged as paedophiles have pounced on developments in the technology.The Internet Watch Foundation said AI videos of abuse had “crossed the threshold” of being near-indistinguishable from “real imagery” and had sharply increased in prevalence online this year.In the first six months of 2025, the UK-based internet safety watchdog verified 1,286 AI-made videos with child sexual abuse material (CSAM) that broke the law, compared with two in the same period last year.The IWF said just over 1,000 of the videos featured category A abuse, the classification for the most severe type of material.The organisation said the multibillion-dollar investment spree in AI was producing widely available video-generation models that were being manipulated by paedophiles

Children limiting own smartphone use to manage mental health, survey finds

Children are increasingly taking breaks from their smartphones to better manage their mental health, personal safety and concentration spans, research has revealed.They are reacting to growing concerns that spending too much time online can be harmful by taking control of their own social media and smartphone use rather than relying on parents to enforce limits, according to experts.The number of 12- to 15-year-olds who take breaks from smartphones, computers and iPads rose by 18% to 40% since 2022, according to the audience research company GWI, drawing on a survey of 20,000 young people and their parents across 18 countries.Prof Sonia Livingstone, the director of the LSE’s Digital Futures for Children centre, said these findings were echoed in soon to be published research, which has found that children and young people are trying various options to manage how their online lives affect their wellbeing, including taking a break from social media, distracting themselves from negativity online, seeking more positive experiences on the internet and in some cases quitting social media altogether.Livingstone said: “Children have got the message – from their parents, the media, their own experiences – that too much social media isn’t always good for them

UK government’s deal with Google ‘dangerously naive’, say campaigners

Google has agreed a sweeping deal with the UK government to provide free technology to the public sector from the NHS to local councils– a move campaigners have called “dangerously naive”.The US company will be asked to “upskill” tens of thousands of civil servants in technology, including in using artificial intelligence, as part of an agreement that will not require the government to pay. It is considered in Whitehall to be giving Google “a foot in the door” as the digitisation of public services accelerates.However, the agreement prompted concerns about the precariousness of UK public data potentially being held on US servers amid the unpredictable leadership of Donald Trump.The Department of Science, Innovation and Technology (DSIT) said Google Cloud, which provides databases, machine learning and computing power, had “agreed to work with the UK government in helping public services use advanced tech to shake off decades old ‘ball and chain’ legacy contracts which leave essential services vulnerable to cyber-attack”
