Oshen's robotic sailboats are powered by the wind and the sun The UK's Royal Navy may return to the age of sail, with a new demonstration involving a flotilla of small, wind-propelled robot boats. Made by Oshen in Plymouth, UK, the vessels, known as C-Stars, are just 1.2 metres long and weigh around 40 kilos. Solar panels power navigation, communications and sensors, while a sail provides propulsion. Deployed as a constellation, the small vessels act as a wide-area sensor network. How the US military wants to use the world's largest aircraft "The simplest way of describing C-Stars is as self-deploying, station-keeping ocean buoys," says Oshen CEO Anahita Laverack .

We pick the sci-fi novels we're most looking forward to reading this month, from a new Brandon Sanderson to the latest from Makana Yamamoto Do you want to travel to Mars, to an alternate version of 1939 London or even to the very far future? If so, then February's science fiction is for you, with all three flavours on offer from our authors. I'm intrigued by a couple of time-travel novels: in we're time-travelling to save the world from global warming, and in, a time-traveller offers romantic salvation for a lonely immortal woman. I'm also keen to read a new entry in one of my favourite genres, fungal horror, thanks to . And I'm ready for a good debate about whether some of the books featured here are science fiction at all - check out new offerings from Brandon Sanderson and Francis Spufford and see what you think.

Members of the New Scientist Book Club give their take on Sierra Greer's award-winning science-fiction novel Annie Bot, our read for February - and the needle swings wildly from positive to negative Annie Bot by Sierra Greer was the Book Club's January read The New Scientist Book Club moved on from reading a classic piece science fiction in December - Iain M. Banks's - to an award-winning sci-fi novel in January: Sierra Greer's, which won the Arthur C. Clarke prize in 2025. I must admit, I was nervous to announce this one to my fellow readers. is the story of a sex robot, owned by a controlling and abusive man. It gets very dark in places, it has a number of sex scenes, and I wanted to make sure you all knew what you were getting into before getting started. That cupboard scene, some way into the book, was super disturbing, for example. It turns out my wariness was warranted.

Alex Garland's 2015 film Ex Machina and Sierra Greer's Annie Bot (pictured below) follow a long tradition of female robots This year's Arthur C. Clarke award for the year's best science fiction novel was awarded last month to Sierra Greer's Annie Bot. Over the course of the novel, Annie, a sentient sex robot programmed to adore her selfish owner, gradually develops a sense of personhood – but she is hardly the first artificial woman to do so. Although the earliest fictional female robots were little more than wind-up toys, they have steadily gained substance until more recent artificial women, like Annie, have become as complex as their human counterparts. Artificial people are both ancient and ubiquitous. "Basically every culture around the world since recorded history has told stories about automatons," says Lisa Yaszek at the Georgia Institute of Technology.

Last month, a new dating app called Volar launched in New York City, with the promise "We go on blind dates. So you don't have to." To sign up, you enter your name and phone number, then submit yourself to a brief interview with a chatbot matchmaker. When I made an account, Volar's bot asked what line of work I was in. "I'm a book critic," I replied.
