To test the safety and security of AI, hackers have to trick large language models into breaking their own rules. It requires ingenuity and manipulation – and can come at a deep emotional cost
A few months ago, Valen Tagliabue sat in his hotel room watching his chatbot, and felt euphoric. He had just manipulated it so skilfully, so subtly, that it began ignoring its own safety rules. It told him how to sequence new, potentially lethal pathogens and how to make them resistant to known drugs.
Tagliabue had spent much of the previous two years testing and prodding large language models such as Claude and ChatGPT, always with the aim of making them say things they shouldn’t. But this was one of his most advanced “hacks” yet: a sophisticated plan of manipulation, which involved him being cruel, vindictive, sycophantic, even abusive. “I fell into this dark flow where I knew exactly what to say, and what the model would say back, and I watched it pour out everything,” he says. Thanks to him, the creators of the chatbot could now fix the flaw he had found, hopefully making it a little safer for everyone.

The then Newcastle manager’s on-air blast at Sir Alex Ferguson remains a classic Premier League moment
Premier League history is littered with red letter days and Monday 29 April 1996 will for ever rank among the most memorable. Thirty years on, recollections of the aftermath of Newcastle’s 1-0 victory at Leeds remain vivid. Keith Gillespie’s goal saw Kevin Keegan’s team move three points behind the leaders, Manchester United, with two fixtures remaining.
Before Newcastle’s visit to Elland Road, Sir Alex Ferguson craftily suggested that Leeds and Nottingham Forest – the team Keegan’s players would visit three days later – would not try as hard as they had against his own side. Ferguson also pointedly reminded everyone Newcastle had agreed to provide the opposition for Stuart Pearce’s testimonial by the Trent later in the year. This backdrop dictated that Keegan used a live post-match television interview with Richard Keys and Andy Gray of Sky Sports to claim the moral high ground while also walking straight into Ferguson’s psychological trap.

Everything was in place for Andrea’s dream celebration in Barbados. Then her close friend was denied the right to walk across a British airport to board a connecting flight

This ‘nonfiction thriller’ takes us through exactly what would happen if Nigel Farage won his dreamed-of majority
For some years now, mainstream British politics has revolved increasingly obsessively around the question of how to stop Nigel Farage. What started a decade ago with Brexit may yet end in a general election that boils down to one question: do you or don’t you want to risk putting this man in Downing Street? That said, we still know surprisingly little about what a Reform government might mean in practice.
Of course, it might never happen. But if it did, what exactly would Farage do with a majority that enabled him to fulfil his wildest dreams? And how well would an unwritten British constitution, still heavily reliant on good chaps voluntarily being good chaps, cope with full-fat populism?

Pace of sea-level rise has turned Outer Banks coastal area into a ‘canary in the coalmine’ for other east coast communities
Moving house has a more literal meaning on Hatteras Island, the slender hook of land that juts off the coast of North Carolina. After a slew of houses toppled spectacularly into the Atlantic Ocean recently, entire buildings are now being lifted on to wheels to flee the rapidly eroding coastline.
Since September, 19 homes have been lost to waves that tore them from their pilings, sending them crashing into other structures like bumper cars before breaking up in the ocean. Spooked homeowners have turned to the unusual services of Barry Crum, a lifelong Hatteras resident who has become the island’s main house mover.

Trump is volatile, capricious and unreasonable – but he belongs to the old world of analogue power. What comes next will be harder to manage
Donald Trump is not impressed by soft power. He respects hard men with military muscle. But he can be moved by pageantry, which is the purpose of King Charles’s visit to Washington this week. Trump is flattered to rub shoulders with majesty. The good vibes are then supposed to radiate warmth through a political relationship that has been chilled by the war in Iran.
It might work, but not for long. Trump’s irritation with Keir Starmer and other European leaders for what he calls cowardice in the Middle East is aggravated daily by evidence that the war is a strategic calamity.

Ruling is blow to Office for Students after it issued record fine for allegations over professor’s trans rights views
Sussex University has overturned a £585,000 fine from England’s higher education watchdog after the high court rejected claims that the university breached free speech regulations in a case involving its former professor Kathleen Stock.
The ruling is a damaging blow to the credibility and management of the Office for Students as the court rejected the regulator’s lengthy investigation involving Stock’s resignation in 2021, which followed protests over her views on transgender rights and gender identity.
