Designed to manoeuvre the smallest classes of satellite, the operation of this Iridium Catalysed Electrolysis CubeSat Thruster (ICE-Cube Thruster) developed with Imperial College in the UK is based on electrolysis.
This tiny fingernail-length space thruster chip runs on the greenest propellant of all: water.
Avoiding any need for bulky gaseous propellant storage, an associated electrolyser runs a 20-watt current through water to produce hydrogen and oxygen to propel the thruster.
Meta Platforms is working on a new artificial-intelligence system intended to be as powerful as the most advanced model offered by OpenAI, the Wall Street Journal reported on Sunday, citing people familiar with the matter.
The Facebook parent is aiming for its new AI model to be ready next year, the Journal said, adding it will be several times more powerful than its commercial version dubbed Llama 2.
Llama 2 is Meta’s open source AI language model launched in July, and distributed by Microsoft’s cloud Azure services to compete with OpenAI’s ChatGPT and Google’s Bard.
Telesurgery or remote surgery is an emerging surgical tool that utilizes is both robotic technology and wireless networking to connect patients and surgeons.
According to recent research published in the Journal of Experimental Medicine, equipping cancer-infecting viruses with tumor-inhibiting genetic cargo boosts the immune system and supports immunotherapy in reducing or totally eradicating aggressive tumours in mice. The findings pave the path for clinical studies combining oncolytic viruses with immunotherapy.
The study states that cancer-infecting viruses can boost immunity of the body and support immunotherapy.
India is building its first manned submersible to study the deep sea and conduct a biodiversity assessment, an announcement that comes days after the country successfully landed a spacecraft near the moon’s south pole.
A trio of scientists who developed the combination drug Trikafta are among the winners of five major awards in life sciences, physics and mathematics.
Self-assembled single vacancies in a 2D transition metal dichalcogenide are used to fabricate atomically precise quantum antidots. The resulting antidots have tunable quantum hole states, which are robust to oxygen substitutional doping, and could have applications in quantum information and photocatalysis technologies.
The Association for Computing Machinery has just put out the finalists for the Gordon Bell Prize award that will be given out at the SC23 supercomputing conference in Denver, and as you might expect, some of the biggest iron assembled in the world are driving the advanced applications that have their eyes on the prize.
The ACM warns that the final system sizes and final results of the simulations and models run are not yet completed, but we have a look at one of them because the researchers in China’s National Supercomputing Center in Wuxi actually published a paper they will formally released in November ahead of the SC23 conference. That paper, Towards Exascale Computation for Turbomachinery Flows, was run on the “Oceanlite” supercomputing system, which we first wrote about way back in February 2021, that won a Gorden Bell prize in November 2021 for a quantum simulation across 41.9 million cores, and that we speculated the configuration of back in March 2022 when Alibaba Group, Tsinghua University, DAMO Academy, Zhejiang Lab, and Beijing Academy of Artificial Intelligence ran a pretrained machine learning model called BaGuaLu, across more than 37 million cores and 14.5 trillion parameters in the Oceanlite machine.
NASA tossed down a grand challenge nearly a decade ago to do a time-dependent simulation of a complete jet engine, with aerodynamic and heat transfer simulated, and the Wuxi team, with the help of engineering researchers at a number of universities in China, the United States, m and the United Kingdom have picked up the gauntlet. What we found interesting about the paper is that it confirmed many of our speculations about the Oceanlite machine.
