We present Imagen, a text-to-image diffusion model with an unprecedented degree of photorealism and a deep level of language understanding. Imagen builds on the power of large transformer language models in understanding text and hinges on the strength of diffusion models in high-fidelity image generation. Our key discovery is that generic large language models (e.g. T5), pretrained on text-only corpora, are surprisingly effective at encoding text for image synthesis: increasing the size of the language model in Imagen boosts both sample fidelity and image-text alignment much more than increasing the size of the image diffusion model. Imagen achieves a new state-of-the-art FID score of 7.27 on the COCO dataset, without ever training on COCO, and human raters find Imagen samples to be on par with the COCO data itself in image-text alignment. To assess text-to-image models in greater depth, we introduce DrawBench, a comprehensive and challenging benchmark for text-to-image models. With DrawBench, we compare Imagen with recent methods including VQ-GAN+CLIP, Latent Diffusion Models, and DALL-E 2, and find that human raters prefer Imagen over other models in side-by-side comparisons, both in terms of sample quality and image-text alignment.

REC Silicon, Ferroglobe to establish traceable US solar supply chain
Posted by Shubham Ghosh Roy in category: futurism
Investments by Hanwha Group and the potential passage of the Solar Energy Manufacturing Act could expand US production of polysilicon and metallurgical-grade silicon.
From pv magazine USA
REC Silicon and Ferroglobe have signed a memorandum of understanding (MOU) to develop an end-to-end US solar supply chain from raw silicon, to polysilicon, and finally fully assembled modules. Recent investment into REC Silicon by the Hanwha Group, in conjunction with Hanwha’s subsidiary Qcells, was the impetus for the MOU.

Scientists Dispel Popular Theory That Earth’s Magnetic Poles Will Flip
Posted by Shubham Ghosh Roy in category: futurism
Earth’s magnetic poles are just experiencing a “soft spot” that will probably disappear in a few hundred years.
In new research, scientists walk back the popular idea that Earth’s magnetic poles will flip at some point soon—an event that would occur for the first time in tens of thousands of years. And while it wouldn’t be the end of the world by any means, it would complicate a lot of things for us. All of that means it’s good news that we likely won’t see a flip for at least a few hundred more years.
In the new paper, published last week in the Proceedings of the National Academy of Sciences, researchers from Lund University in Sweden and Oregon State University identify some of Earth’s current magnetic anomalies and position them in the larger context of the last 9,000 years. Amazingly, we have pretty complete magnetic field data over that entire period. But to understand what’s going on, first we should take a crash course in Earth’s magnetic field.

AMD might have to wait in line behind Intel and Apple for 3nm allocation at TSMC. It’s not clear if the Taiwanese foundry can meet demand.

The Earth moves far under our feet: A new study shows that the inner core oscillates
Posted by Saúl Morales Rodriguéz in category: futurism
USC scientists have found evidence that the Earth’s inner core oscillates, contradicting previously accepted models that suggested it consistently rotates at a faster rate than the planet’s surface.
Their study, published today in Science Advances, shows that the inner core changed direction in the six-year period from 1969–74, according to the analysis of seismic data. The scientists say their model of inner core movement also explains the variation in the length of day, which has been shown to oscillate persistently for the past several decades.
“From our findings, we can see the Earth’s surface shifts compared to its inner core, as people have asserted for 20 years,” said John E. Vidale, co-author of the study and Dean’s Professor of Earth Sciences at USC Dornsife College of Letters, Arts and Sciences. “However, our latest observations show that the inner core spun slightly slower from 1969–71 and then moved the other direction from 1971–74. We also note that the length of day grew and shrank as would be predicted.
