In a basement beneath City St George’s, University of London, senior leaders from NATO watch as four research teams from the UK, US, Netherlands and Austria, showcase their AI-controlled, autonomous drones. The groups are competing against each other as part of the NATO-funded SAPIENCE programme, designed to accelerate progress with this emerging technology, particularly in a world where drones on the battlefield are changing warfare, as demonstrated in Ukraine. “We are still trying to understand what are the impacts of drones,” says Claudio Palestini, head of NATO’s Science for Peace and Security programme. “We have regular contact with Ukraine where we understand what they are doing with technology,” he says. “NATO is adapting to this new way of fighting, we are ...

Ekkehard Peik is a clock-maker. But instead of spending his days looking at tiny cogs and springs through a magnifying glass, the tools of his trade are powerful lasers, wires and, occasionally, radioactive atoms. Peik, director of the German metrology institute (PTB), is one of a handful of physicists who have spent the best part of three decades trying to make the most accurate timepiece in the universe. Since the 1950s, researchers have been constructing atomic clocks, the very best of which are now so accurate they only lose a second in around 31 billion years. But these are about to be replaced by a new model: the nuclear clock. This promises to outperform its atomic counterparts both in terms of precision and accuracy. A nuclear clock would, in principle, only d...

During the summer of 2022, I was part of a 16-member crew doing trail maintenance in California’s Trinity Alps. The job required us to live in tents and work outside. For several days, smoke from three different forest fires in the region had been burning our throats and giving us headaches, despite the masks we wore. Finally, one morning our supervisor stood in front of us, holding back tears because the forest he loved was burning so intensely. “You have to go; it’s not safe,” he said. Two years later, in 2024, the Park Fire blazed across acres of forest three hours south of where my crew had been evacuated, belching smoke into areas miles away from the burn site. Over 400,000 acres of forest burned and over 600 structures have been destroyed by the fire, according to CalFire. ...

Many AI-generated images look realistic until you take a closer lookMidJourney Did you notice that the image above was created by artificial intelligence? It can be difficult to spot AI-generated images, video, audio and text at a time when technological advances are making them increasingly indistinguishable from much human-created content, leaving us open to manipulation by disinformation. But by knowing the current state of the AI technologies used to create misinformation, and the range of telltale signs that what you are looking at might be fake, you can help protect yourself from being taken in. World leaders are concerned. According to a report by the World Economic Forum, misinformation and disinformation may “radically disrupt electoral processes in several ec...
