A US physicist and a Canadian computer scientist have won this year's Turing Award for their invention of a form of seemingly unbreakable encryption. Charles H Bennett and Gilles Brassard's work, which dates back to 1984, is known as quantum cryptography and has redefined secure communication and computing, the award's body said. Scientists believe their work will be central to electronic communications in a world that depends heavily on data-sharing, but which for years has been trying to develop more powerful quantum computers. The Turing Award, named after the mathematician and code-breaker Alan Turing, is known as the Nobel Prize of computing. It comes with a $1m (£800,000) prize.

We have listened, Technology Secretary Liz Kendall said on Wednesday, saying the government no longer favours that approach. However, the government's position is now unclear, saying it no longer has a preferred option for what to do next. Kendall said the government had engaged extensively with people in the creative and AI industries. It is attempting to balance the interests of the two sectors by giving creatives control how their work is used, while recognising AI models need to be trained on work such as writing, music and video. In a report published on Wednesday, the government said there was no consensus on how these objectives should be achieved.

Three years on from the release of ChatGPT, two broad camps have formed: those people who refuse to use it, and those who use it every day. Three years on from the release of ChatGPT, two broad camps have formed: those people who refuse to use it, and those who use it every day. We asked experts about the most responsible ways to use AI tools - here's what they said Three years on from the release of ChatGPT, two broad camps have formed: those people who refuse to use it, and those who use it every day. A 2025 survey by the Pew Research Center found that one-third of US adults say they have been using ChatGPT. This includes 58% of US adults under 30 - roughly double the share two years ago.

Iran war: What is happening on day 19 of US-Israel attacks? Iran has pledged "revenge" after Israeli strikes killed security chief Ali Larijani and commander of Basij paramilitary forces Gholamreza Soleimani, with Foreign Minister Abbas Araghchi saying Tehran's political system remains strong as the war entered its 19th day . Iran launched more attacks on Israel, causing extensive property damage, after an earlier strike killed two people in Ramat Gan. Political tensions are also rising in the United States, as senior counterterrorism official Joe Kent resigned, saying "we started this war due to pressure from Israel and its powerful American lobby". Meanwhile, President Donald Trump criticised NATO allies and partners for failing to provide stronger military support in efforts to end Iran's chokehold on the Strait of Hormuz.

'I've applied for 500 jobs in two months since graduating' You have to work 10 times harder to work for a role that 10 years ago you could have got very easily straight out of university, says 22-year-old business management graduate Charlotte Briggs. Within two months she had applied for 500 roles. It's quite upsetting because I've worked really hard for the last three years to achieve a 2:1 just to be rejected for not having experience. Although her job search sounds extreme, it may not be that unusual. According to latest ONS figures, 22.5% of people aged 16 to 24 cannot find work, putting London as the UK region with the second highest rate of youth unemployment.

Higgs Boson breakthrough was UK triumph, but British physics faces'catastrophic' cuts When the Nobel Prize in Physics was announced in Stockholm in October 2013, the world was watching. Among the names read out was Prof Peter Higgs, the British theorist who, nearly half a century earlier, had predicted the existence of a particle believed to hold the cosmos together - the Higgs boson. The announcement, broadcast live from Sweden, was what many scientists had hoped for since a year earlier, when experiments at CERN had finally confirmed Higgs's theory by discovering the Higgs boson - hailed as one of the biggest discoveries in a generation. At the time Higgs, who has since passed away, said in a statement: I hope this recognition of fundamental science will help raise awareness of the value of blue-sky research. Blue-sky research asks questions to understand the universe, rather than design new products.

Ad for AI editing app which said it could'remove anything' banned An advert for a video and image editing tool that implied viewers could digitally remove a woman's clothing has been banned by the UK advertising regulator. The YouTube ad for PixVideo - AI Video Maker, seen in January, showed a before and after image of a young women, with red scribble overlaid on her midriff in the former, and parts of her bare skin exposed in the latter. Text across the bottom of the picture stated: Erase anything followed by a heart-eyes emoji. Eight people complained to the Advertising Standards Authority (ASA) that the ad sexualised and objectified women, and was irresponsible, offensive and harmful. It is not clear whether the image in the ad is of a real person or is itself AI-generated, with the ASA telling the BBC making such an assessment had not been part of its investigation.

The BBC has obtained footage and interviews from the Iranian capital Tehran which evoke a city of strained nerves, of constant waiting for the next air strike and relentless fear of the state security apparatus. The identities of the people in this report have been protected. While independent journalists still try to gather testimony that offers a credible alternative view, they run the risk of arrest, torture and possibly worse. Displaced Palestinians were told to secure their tents to prevent them being blown away as a storm swept through the enclave. Video filmed by a witness and verified by the BBC shows a drone crashing close to the airport.

Nvidia faces gamer backlash over'breakthrough' AI graphics feature A new feature from chip-maker Nvidia that promises cinematic-quality graphics using AI has prompted a backlash online, despite the company claiming it would reinvent what is possible in video games. Nvidia said the DLSS 5 tool, which will be rolled out this autumn, would allow games to have photoreal computer graphics previously only achieved in Hollywood visual effects. In images shared with the media, the tech was shown radically changing the appearance of characters and environments in games such as Resident Evil Requiem and Hogwarts Legacy. But some industry professionals said its use of AI went too far, making graphics feel airbrushed and hollow. Clearly this is a massive glow-up for environments, said video game critic Alex Donaldson on Bluesky.

Ukrainian President Volodymyr Zelensky is set to visit Prime Minister Sir Keir Starmer in the UK on Tuesday to agree a new defence partnership aimed at tackling cheap attack drones. Downing Street said the deal would bring together Ukrainian expertise and the UK's industrial base to manufacture and supply drones and other capabilities. The two leaders are also expected to discuss further support Ukraine against Russia's full-scale invasion, now in its fourth year. Their meeting comes as the US-Israeli war with Iran enters a third week, during which US President Donald Trump has criticised the UK and other countries over the extent of their response to the conflict. Under the partnership between the UK and Ukraine, closer co-operation in the defence industries will also be sought with third countries as part of efforts to bolster international security.
