Wolverhampton university tackles water leakage with AI satellites
University researchers in Wolverhampton have been awarded £1.3m to use AI-driven satellite technology to help solve the costly and time-consuming process of detecting water leaks.Alongside South Staffs Water, the team will build, launch and operate a fleet of Low Earth Orbit (LEO) micro satellites, which can find leaks "with unprecedented efficiency and precision".Using AI techniques with high-resolution satellite imagery, researchers said they want to deliver faster, more accurate and cost-effective monitoring of leakage.Detection costs are projected to be at least 10 times lower than current satellite-based methods, the university said.
Water loss is a persistent issue for the UK industry, with an estimated 19% of the supply lost before it reaches consumers, according to Water UK, costing £3.2bn annually across the utilities sector.The university said traditional detection methods, such as acoustic monitoring and tracer gas detection, are labour-intensive and inefficient, typically locating fewer than one leak per day per crew and costing between £250 and £2,000 per inspection.
Other satellite-based technologies have improved detection rates, but high operational costs and image refresh rates of between seven and 14 days still limit their effectiveness.Using the £1.3m funding from water regulation service Ofwat's Innovation Fund, the team said they can create high-frequency imaging and have fresh data every six hours with sharper resolution to pinpoint leaks.The AI-powered detection then reduces costs and enables rapid deployment beyond the UK, the university said.Professor Mohammad Patwary, director of the university's digital innovation and solution centre (DISC) and project lead, said: "This Ofwat initiated opportunity marks a major innovation leap for the UK, enhancing the water industry's efficiency and infrastructure longevity, while creating a platform for critical sectors, like energy, transport, and telecom, and positioning the UK as a leader in LEO satellite-driven innovation and productivity."The team will use six satellites as part of the project called Space Eye and liaise with several other water firms in the UK.

AI-driven search ad spending set to surge to $26 billion by 2029, data shows
June 4 (Reuters) - Spending on AI-powered search advertising is poised to surge to nearly $26 billion by 2029 from just over $1 billion this year in the U.S., driven by rapid adoption of the technology and more sophisticated user targeting, data from Emarketer showed on Wednesday. Companies that rely on traditional keyword-based search ads could experience revenue declines due to the growing popularity of AI search ads, which offer greater convenience and engagement for users, according to the research firm. Search giants such as Alphabet-owned (GOOGL.O), opens new tab Google and Microsoft's (MSFT.O), opens new tab Bing have added AI capabilities to better compete with chatbots such as OpenAI's ChatGPT and Perplexity AI, which provide users with direct information without requiring to click through multiple results. Apple (AAPL.O), opens new tab is exploring the integration of AI-driven search capabilities into its Safari browser, potentially moving away from its longstanding partnership with Google. The report has come as concerns grew about users increasingly turning to the chatbots for conversational search and AI-powered search results could upend business models of some companies. Online education firm Chegg (CHGG.N), opens new tab said in May that it would lay off about 248 employees as it looks to cut costs and streamline operations because students are using AI-powered tools including ChatGPT over traditional edtech platforms. "Publishers and other sites are feeling the pain from AI search. As they lose out on traffic, we're seeing publishers lean into subscriptions and paid AI licensing deals to bolster revenue," Emarketer analyst Minda Smiley said. GRAPHIC AI search ad spending is expected to constitute nearly 1% of total search ad spending this year and 13.6% by 2029 in the U.S., according to Emarketer. Sectors such as financial services, technology, telecom, and healthcare are embracing AI as they are seeing clear advantages in using the technology to enhance their ad strategies, while the retail industry's adoption is slow, the report said. Google recently announced the expansion of its AI-powered search capabilities into the consumer packaged goods sector through enhancements in Google Shopping.

Abba singer Björn Ulvaeus teases fans in London with AI-assisted musical
After bringing a blockbuster hologram version of Abba to a purpose-built venue in east London, Björn Ulvaeus's next technological exploration is a musical that he's written with the help of artificial intelligence. Ulvaeus told an audience at SXSW London that he was 'three-quarters' of the way through writing a new musical which he has created with assistance from AI songwriting tools. He did admit the technology had limitations when it comes to songwriting, saying it was 'lousy at [writing a whole song]' and 'very bad at lyrics' but was helpful whenever the 80-year-old songwriter reached a creative impasse. 'You can prompt a lyric you have written about something, and you're stuck maybe, and you want this song to be in a certain style,' Ulvaeus said. 'You can ask it, how would you extend? Where would you go from here? It usually comes out with garbage, but sometimes there is something in it that gives you another idea.' The use of AI is a hugely contentious issue in the music industry. This year, Dua Lipa and Paul McCartney were among hundreds of artists who signed an open letter urging the prime minister to protect artists' copyright and not 'give our work away' to big tech. Ulvaeus said AI isn't the creative threat but rather a collaborator. 'It's fantastic. It is such a great tool,' he added. 'It is like having another songwriter in the room with a huge reference frame. It is really an extension of your mind. You have access to things that you didn't think of before.' The musical is far from Ulvaeus's first flirtation with technology. Abba Voyage, the concert which launched three years ago in a purpose-built arena that featured digital avatars of the band, has been a huge success and was described as a 'dazzling retro-futurist extravaganza' by the Guardian. It was a risky venture as Pophouse Entertainment, the company behind the project needed to bring in £140m in order to break even. He told the audience at SXSW London that he embraced experimental approaches to songwriting and studio technology much earlier in his career. This experimental approach is characteristic of Ulvaeus's career-long fascination with technological innovation. During his time in Abba, he along with bandmate Benny Andersson 'always wanted the latest thing', and were among the first to use the Mini Moog synthesizer and use digital recording machines in their studio. 'We were always on the lookout for, you know, you would hear a sound on the record. How was that done? And then you get that stuff,' said. The Abba songwriter told the audience that he sees AI as the latest evolution in his career rather than a threat which is how it is perceived by many. 'I actually wake up curious every morning,' Ulvaeus said, explaining the drive that has kept him creating decades after Abba's peak. 'Everything's really after our wanting to try new things.'

British Army supplier founded by Tony Blair's son raises $20m
A start-up co-founded by Sir Tony Blair's son Nick has raised $20m (£15m) to develop simulation technology for the British Army and Nato. Skyral, which is working on next-generation training programmes for the military, has secured new funding from existing investor NOIA Capital. Accrete Capital will take a minority stake. Nick Blair, the son of the former Labour prime minister and co-founder of Skyral, said the deal was an endorsement of the 'excellence of UK innovation'. It comes as the company awaits the outcome of a £2bn bidding process to redesign the British Army's training systems and technology. Skyral is part of a consortium which is among the frontrunners to become the Army's strategic training partner. This would see it handling exercises for 60,000 British soldiers each year and supplying everything from logistical support to virtual simulations and data analysis. Skyral's technology means it can create 'digital twins' that model human behaviour or real-world environments. This allows the military to run simulations in a virtual world alongside real training exercises. The Ministry of Defence is in the process of picking between two final bids to begin work next year. Rival bids from British contractor QinetiQ and French business Leonardo have already been ruled out. Future wargaming could see soldiers conducting exercises with their battleline units and military hardware, while away from the frontline analysts and officers simulate logistical challenges, cyber attacks or managing civilian populations. Sir Keir Starmer this week revealed his plans to boost military spending as part of the strategic defence review, with a focus on new technologies such as artificial intelligence (AI), drones and cyber warfare. Jason Kennedy, Skyral's chief executive and another co-founder of the business, said the defence review had 'prioritised digital advantage', an area where Skyral had expertise. He said: 'We simulate really large complex systems. We can simulate the whole critical national infrastructure of a country, or a city, or its people. We help train for the modern world.' Mr Blair joined Skyral as chairman last year. He is listed as one of its co-founders. His brother, Euan, runs Multiverse, a business that helps train apprentices using technology and is valued at £1bn. Skyral was previously part of £2bn technology business Improbable, but was spun out of the UK company two years ago. Improbable had spent more than $100m developing Skyral before selling it to Luxembourg-based fund NOIA Capital in 2023. It had previously worked with the British and American military as well as Nato.
