Investigators have failed to find the root cause of the substation fire that shut Heathrow airport in March, six weeks after the government ordered an “urgent” investigation.A preliminary report from the National Energy System Operator (Neso) ruled out any suspicious activity behind the outage which cut power to the airport, affecting more than 1,350 flights and almost 300,000 passengers.But the state-owned body admitted that the “root cause of the fire”, which also left about 67,000 homes without power, still “remains unknown”.The system operator has promised to continue its investigation into the maintenance history and design of the 57-year-old power substation in west London that caught fire on 20 March to establish whether it was meeting its legal requirements.It will also examine the configurations of the airport’s private electricity network, which took hours to repower after the outage, even as two nearby substations continued to operate as normal.

Heathrow took a further seven hours to open after the power was restored, according to the report, meaning flights were disrupted for almost 24 hours after the fire broke out,Neso said a dedicated team reviewed more than 600 pieces of evidence from the companies involved in the incident to inform its interim report,It expects to publish a final report by the end of June,In late March, Ed Miliband, the energy secretary, ordered the system operator to undertake an “urgent” investigation into what happened and provide its initial findings within six weeks of the blaze,On Thursday, he said: “We now await the full report to understand what happened and learn lessons to strengthen UK energy resilience and protect our critical national infrastructure.

”Heathrow airport said the report raised questions for National Grid – the owner of the substation that caught fire – and Scottish and Southern Electricity Networks (SSEN), responsible for power distribution in the area.A spokesperson for the airport said: “Further clarity on how the fire started and why two transformers were subsequently impacted can help ensure greater resilience for the UK’s energy grid moving forward.”The energy companies involved in the outage will also face an inquiry by the industry’s regulator, Ofgem, which is responsible for approving the investments and revenues of electricity network operators.Sign up to Business TodayGet set for the working day – we'll point you to all the business news and analysis you need every morningafter newsletter promotionHeathrow will also launch an internal investigation into its resilience, led by Ruth Kelly, the former secretary of state for transport and independent board member of the airport.Executives from the energy and airline industries were summoned within days of the outage to appear before parliament’s cross-party transport select committee.

Heathrow’s chief executive, Thomas Woldbye, apologised for the disruption.He told MPs that a power outage on this scale had been seen as a “very low probability event” and the airport had paid for a “supposedly resilient” supply.National Grid and SSE said in separate statements that they would continue to work closely with Neso in its investigation and looked forward to the full report.

Pro-Russian hackers claim to have targeted several UK websites

A pro-Russian hacking group has claimed to have successfully targeted a range of UK websites, including local councils and the Association for Police and Crime Commissioners, during a three-day campaign.In a series of social media posts, the group calling itself NoName057(16) suggested it had made a number of websites temporarily inaccessible, although it is understood the attacks were not wholly successful.The hackers sought to flood a range of websites with internet traffic in what is known as a distributed denial-of-service (DDoS) attack. The group wrote on X: “Britain is invested in the escalation of the [Ukraine] conflict, and we are disconnecting its resources.”Its success was limited, however, with councils in Blackburn and Darwen and Exeter among those reporting that their websites were unaffected despite the hacking group’s claims of success

‘It cannot provide nuance’: UK experts warn AI therapy chatbots are not safe

Having an issue with your romantic relationship? Need to talk through something? Mark Zuckerberg has a solution for that: a chatbot. Meta’s chief executive believes everyone should have a therapist and if they don’t – artificial intelligence can do that job.“I personally have the belief that everyone should probably have a therapist,” he said last week. “It’s like someone they can just talk to throughout the day, or not necessarily throughout the day, but about whatever issues they’re worried about and for people who don’t have a person who’s a therapist, I think everyone will have an AI.”The Guardian spoke to mental health clinicians who expressed concern about AI’s emerging role as a digital therapist

Amazon makes ‘fundamental leap forward in robotics’ with device having sense of touch

Amazon said it has made a “fundamental leap forward in robotics” after developing a robot with a sense of touch that will be capable of grabbing about three-quarters of the items in its vast warehouses.Vulcan – which launches at the US firm’s “Delivering the Future” event in Dortmund, Germany, on Wednesday and is to be deployed around the world in the next few years – is designed to help humans sort items for storage and then prepare them for delivery as the latest in a suite of robots which have an ever-growing role in the online retailer’s extensive operation.Aaron Parness, Amazon’s director of robotics, described Vulcan as a “fundamental leap forward in robotics. It’s not just seeing the world, it’s feeling it, enabling capabilities that were impossible for Amazon robots until now.”The robots will be able to identify objects by touch using AI to work out what they can and can’t handle and figuring out how best to pick them up

‘The crux of all evil’: what happened to the first city that tried to ban smartphones for under-14s?

At 3.12pm on a sunny spring afternoon in St Albans, Yasser Afghen reaches for the iPhone in his jeans pocket, hoping to use the three minutes before his son emerges from his year 1 primary class to scroll through his emails. As he lifts the phone to his face, Matthew Tavender, the head teacher of Cunningham Hill school, strides across the playground towards him. Afghen smiles apologetically, puts his phone away, and spends the remaining waiting time listening to the birdsong in the trees behind the school yard.A one-storey 1960s block with 14 classrooms backing on to a playing field, Cunningham Hill primary feels like an unlikely hub for a revolution

Mark Zuckerberg tried to convince us he was human. Sorry, ZuckBot: you’ve failed | Arwa Mahdawi

Over the past few years Mark Zuckerberg has been conducting a very expensive experiment. If he grows his hair and revamps his wardrobe, will it make him seem more relatable? If he takes up mixed martial arts, goes wild boar hunting, and tells manosphere-adjacent podcasters such as Joe Rogan that companies need more “masculine energy”, will red-blooded American males respect him? With the help of a small army of stylists, personal trainers and PR gurus, could Zuck transform himself from an unlikable dork into an alpha bro?For a brief moment, the answer to all that seemed to be a tentative “yes”. Zuck’s shock of shaggy new hair made the billionaire seem less like three Lego figures in a trenchcoat and more like an adult human male. His gold chains and jazzy new outfits sparked excited chatter of a “Zucknaissance”. The Meta billionaire also had a lucky break, PR-wise, in 2023 when Elon Musk, the world’s least self-aware man, challenged him to a cage brawl

OpenAI reverses course and says non-profit arm will retain control of firm

OpenAI has reversed course in the process of transforming into a for-profit entity, announcing on Monday that its non-profit arm would continue to control the business that makes ChatGPT and other artificial intelligence (AI) products. Previously, the company had sought more independence for its for-profit division.“We made the decision for the nonprofit to stay in control after hearing from civic leaders and having discussions with the offices of the Attorneys General of California and Delaware,” said CEO Sam Altman in a letter to employees. Altman and the chair of OpenAI’s non-profit board, Bret Taylor, said the board made the choice for the non-profit to retain control of OpenAI.A press release from the company said that the for-profit portion of the company, through which Altman has been able to raise billions to fund OpenAI’s work, would transition to a public benefit corporation, a mission-driven designation for a corporate structure that is still aimed at profit but also “has to consider the interests of both shareholders and the mission”
