Computer scientists at the University of California San Diego are showing how soil microbes can be harnessed to fuel low-power sensors. This opens new possibilities for microbial fuel cells (MFCs), which can power soil hydration sensors and other devices.
Led by Department of Computer Science and Engineering (CSE) Assistant Professor Pat Pannuto and Gabriel Marcano, a Ph.D. student working with Pannuto, this research was presented today at the first Association for Computer Machinery (ACM) Workshop on No Power and Low Power Internet of Things.
“Our most immediate applications are in agricultural settings, trying to create closed-loop controls. First for watering, but eventually for fertilization and treatment: sensing nitrates, nitrogen, phosphorous, potassium. This could help us understand how to limit run off and other effects,” said Pannuto, senior author on the study titled “Soil Power? Can Microbial Fuel Cells Power Non-Trivial Sensors?”
Back in January during their CES 2022 keynote, NVIDIA teased the GeForce RTX 3,090 Ti, an even more powerful version of NVIDIA’s flagship card for the high-end gaming and content creation markets. At the time, NVIDIA told us to expect more information later in January, only for January (and February) to come and go without further mention of the card. But now, in the waning days of March, the GeForce RTX 3,090 Ti’s day has come, as NVIDIA is launching their new flagship video card today.
So what is the RTX 3,090 Ti? In short, it’s every last bit of performance that NVIDIA can muster out of their Ampere architecture – the swan song for an architecture that has carried NVIDIA through the last 18 months. Whereas the original RTX 3,090 left a bit of performance on the table for yield or performance reasons, such as a couple of SMs or keeping TDPs to just 350 Watts, RTX 3,090 Ti leaves all of that behind. It’s all the Ampere that Ampere can be, with a fully-enabled GA102 GPU, better GDDR6X memory, and few (if any) limits on performance.
But Ampere unconstrained is going to cost you. While the original RTX 3,090 launched at an already high $1499, RTX 3,090 Ti ratchets that up further to $1999. And ongoing market distortions (i.e. the chip crunch) will likely compound that further, judging from RTX 3,090 prices. But regardless, the RTX 3,090 Ti isn’t priced to be competitive; it’s priced to be elite. NVIDIA never did produce a true Titan card for this generation, so the RTX 3,090 Ti is set to be the next best thing.
Hunter Biden DID help secure millions in funding for US contractor in Ukraine specializing in deadly pathogen research, laptop emails reveal, raising more questions about the disgraced son of then vice president. This Biolabs Biden Jr.’s scandal is what the U.S. media try to hush up… but not for long.
Email emails and correspondence obtained by DailyMail.com from Hunter’s abandoned laptop show he helped secure millions for Metabiota.
Tiny biological computers made of DNA could revolutionize the way we diagnose and treat a slew of diseases, once the technology is fully fleshed out. However, a major stumbling block for these DNA-based devices, which can operate in both cells and liquid solutions, has been how short-lived they are. Just one use and the computers are spent.
Now, researchers at the National Institute of Standards and Technology (NIST) may have developed long-lived biological computers that could potentially persist inside cells. In a paper published in the journal Science Advances, the authors forgo the traditional DNA-based approach, opting instead to use the nucleic acid RNA to build computers. The results demonstrate that the RNA circuits are as dependable and versatile as their DNA-based counterparts. What’s more, living cells may be able to create these RNA circuits continuously, something that is not readily possible with DNA circuits, further positioning RNA as a promising candidate for powerful, long-lasting biological computers.
Much like the computer or smart device you are likely reading this on, biological computers can be programmed to carry out different kinds of tasks.
At GTC 2022, Nvidia CEO Jensen Huang finally shared more details around the company’s Arm endeavors as he unveiled the company’s new 144-core Grace CPU Superchip, the company’s first CPU-only Arm chip designed for the data center. The Neoverse-based system supports Arm v9 and comes as two CPUs fused together with Nvidia’s newly branded NVLink-C2C interconnect tech. Nvidia claims the Grace CPU Superchip offers 1.5X more performance in a SPEC benchmark than two of the last-gen 64-core AMD EPYC processors in its own DGX A100 servers, and twice the power efficiency of today’s leading server chips. Overall, Nvidia claims the Grace CPU Superchip will be the fastest processor on the market when it ships in early 2023 for a wide range of applications, like hyperscale computing, data analytics, and scientific computing.
