Thousands of hills across Britain could be transformed into renewable energy batteries thanks to a new ‘high-density’ hydropower system buried underground. Developed by UK startup RheEnergise, the system puts a modern spin on pumped storage hydro, a centuries-old technology which accounts for 95% of today’s energy storage capacity. Pumped storage hydro uses surplus electricity to pump water into an uphill reservoir, later releasing it back downhill over a set of turbines and into the original lake, generating electricity on demand. Except RheEnergise’s hydro system doesn’t use water at all, but a proprietary high-density fluid. Named R-19 it is 2.5 times…

How RISC-V can usurp Arm as the Switzerland of computer chips

In the divided world of semiconductors, Arm is frequently compared to Switzerland. The UK-based business is built on a foundation of neutrality. Rather than build chips, Arm merely designs their blueprints. The company then licences the IP to almost every major semiconductor maker without directly competing against them. That approach — as well as the energy-efficient architectures — has driven Arm’s designs into over 95% of smartphones, alongside cars, computers, and countless other applications. But the independence that underpins Arm has become contentious. Meanwhile, a budding contender has emerged with a promise of true impartiality: the RISC-V Foundation.  The anxieties…

A team of researchers at King’s College London, has demonstrated that, despite being the more vulnerable group when it comes to cyber abuse, women engage much less than men with security and privacy tech.  Led by Dr Kovila Coopamootoo, lecturer in Computer Science within the Cyber Security Group at King’s College, the research revealed a significant gender gap in the utilisation of tools designed to keep users safe online.  From a survey of 600 people, in near equal proportion men and women, the team concluded that the habits of protecting oneself from cyber harassment and crime differ greatly between the…

The UK’s first bank account dedicated to accelerating science and technology is set to launch next month.  Science Card is the brainchild of Daniel Baeriswyl — during his PhD in biomedical engineering at UCL, he cultivated an appreciation of the importance of life-saving scientific research, but also the runway it requires. “I found it interesting that the investment side is so heavy on financial services, but by comparison, life-changing innovation is very underfunded,” said Baeriswyl, who also co-founded machine learning platform Marget Carpet AI, acquired by Blockchain.com last year.      The entrepreneur is looking to bridge the gap between…

Einstein, Newton could have been wrong about gravity, Gaia telescope data reveals

A groundbreaking study, based on observations from the European Space Agency’s billion-pixel Gaia space telescope, has revealed a “gravitational anomaly” that challenges our fundamental understanding of the universe. The anomaly occurs when loosely orbiting stars, known as wide binaries, seem to move in ways that defy standard models of gravity established by Albert Einstein and Isaac Newton.   Astronomer Kyu-Hyun Chae from Sejong University in South Korea made the discovery while studying binary star systems, which refer to two stars that orbit each other. At accelerations of lower than 0.1 nanometres per second squared, the orbit of the two stars deviated…
