| 12:02a | First RISC-V Computer Chip Lands At the European Processor Initiative An anonymous reader quotes a report from The Register: The European Processor Initiative (EPI) has run the successful first test of its RISC-V-based European Processor Accelerator (EPAC), touting it as the initial step towards homegrown supercomputing hardware. EPI, launched back in 2018, aims to increase the independence of Europe's supercomputing industry from foreign technology companies. At its heart is the adoption of the free and open-source RISC-V instruction set architecture for the development and production of high-performance chips within Europe's borders. The project's latest milestone is the delivery of 143 samples of EPAC chips, accelerators designed for high-performance computing applications and built around the free and open-source RISC-V instruction set architecture. Designed to prove the processor's design, the 22nm test chips -- fabbed at GlobalFoundries, the not-terribly-European semiconductor manufacturer spun out of AMD back in 2009 -- have passed initial testing, running a bare-metal "hello, world" program as proof of life. It's a rapid turnaround. The EPAC design was proven on FPGA in March and the project announced silicon tape-out for the test chips in June -- hitting a 26.97mm2 area with 14 million placeable instances, equivalent to 93 million gates, including 991 memory instances. While the FPGA variant, which implemented a subset of the functions of the full EPAC design, was shown booting a Linux operating system, the physical test chips have so far only been tested with basic bare-metal workloads -- leaving plenty of work to be done. Earlier today, the UK government released its 10-year plan to make the country a global "artificial intelligence superpower," seeking to rival the likes of the U.S. and China. "The so-called 'National Artificial Intelligence Strategy' is designed to boost the use of AI among the nation's businesses, attract international investment into British AI companies and develop the next generation of homegrown tech talent," reports CNBC.

| 8:02p | Smallest-Ever Human-Made Flying Structure Is a Winged Microchip, Scientists Say An anonymous reader quotes a report from NPR: It's neither a bird nor a plane, but a winged microchip as small as a grain of sand that can be carried by the wind as it monitors such things as pollution levels or the spread of airborne diseases. The tiny microfliers, whose development by engineers at Northwestern University was detailed in an article published by Nature this week, are being billed as the smallest-ever human-made flying structures. The devices don't have a motor; engineers were instead inspired by the maple tree's free-falling propeller seeds -- technically known as samara fruit. The engineers optimized the aerodynamics of the microfliers so that "as these structures fall through the air, the interaction between the air and those wings cause a rotational motion that creates a very stable, slow falling velocity," said John A. Rogers, who led the development of the devices. "That allows these structures to interact for extended periods with ambient wind that really enhances the dispersal process," said the Northwestern professor of materials science and engineering, biomedical engineering and neurological surgery. The wind would scatter the tiny microchips, which could sense their surrounding environments and collect information. The scientists say they could potentially be used to monitor for contamination, surveil populations or even track diseases. Their creators foresee microfliers becoming part of "large, distributed collections of miniaturized, wireless electronic devices." In other words, they could look like a swarm. "We think that we beat nature," Rogers said. "At least in the narrow sense that we have been able to build structures that fall with more stable trajectories and at slower terminal velocities than equivalent seeds that you would see from plants or trees."
