  摘要：The pursuit of artificial general intelligence (AGI) continuously demands higher computing performance. Despite the superior processing speed and efficiency of integrated photonic circuits, their capacity and scalability are restricted by unavoidable errors, such that only simple tasks and shallow models are realized. To support modern AGIs, we designed Taichi-large-scale photonic chiplets based on an integrated diffractive-interference hybrid design and a general distributed computing archite...

  摘要：Symbiotic interactions were key to the evolution of chloroplast and mitochondria organelles, which mediate carbon and energy metabolism in eukaryotes. Biological nitrogen fixation, the reduction of abundant atmospheric nitrogen gas (N-2) to biologically available ammonia, is a key metabolic process performed exclusively by prokaryotes. Candidatus Atelocyanobacterium thalassa, or UCYN-A, is a metabolically streamlined N-2-fixing cyanobacterium previously reported to be an endosymbiont of a mari...

• Modern approaches to therapeutic oligonucleotide manufacturing AI翻译

  摘要：Therapeutic oligonucleotides are a powerful drug modality with the potential to treat many diseases. The rapidly growing number of therapies that have been approved and that are in advanced clinical trials will place unprecedented demands on our capacity to manufacture oligonucleotides at scale. Existing methods based on solid-phase phosphoramidite chemistry are limited by their scalability and sustainability, and new approaches are urgently needed to deliver the multiton quantities of oligonu...

• Teach philosophy of science AI翻译
  作者：Thorp, H. Holden
  摘要：Much is being made about the erosion of public trust in science. Surveys show a modest decline in the United States from a very high level of trust, but that is seen for other institutions as well. What is apparent from the surveys is that a better explanation of the nature of science-that it is revised as new data surface-would have a strong positive effect on public trust. Because scientists are so aware of this feature, it is often taken for granted that the public understands this too. A s...
