Among the many benefits of artificial intelligence touted by its proponents is the technology’s potential ability to help solve climate change. If this is indeed the case, the recent step changes in AI couldn’t have come any sooner. This summer, evidence has continued to mount that Earth is already transitioning from warming to boiling.  However, as intense as the hype has been around AI over the past months, there is also a lengthy list of concerns accompanying it. Its prospective use in spreading disinformation for one, along with potential discrimination, privacy, and security issues. Furthermore, researchers at the University of…

A new watermarking tool detects pirated content from a single smartphone photo or screenshot. The system was developed by castLabs, a video software provider based in Berlin. The company says the tech can protect videos, images, documents, and designs from piracy and intellectual property theft. It can also spot media that’s been manipulated for disinformation. To safeguard the content, an algorithm first embeds a hidden watermark within a digital asset. Detailed user data, including IDs, IP addresses, and session information, can be stored in the watermark.  When a user takes a picture of the content, a cloud-based extractor scans the…

Waterless hydro tech can turn hills into giant batteries

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

Posted In: Uncategorized


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…
