2023/6/5
The vast majority of absorbent materials will lose their ability to retain water as temperatures rise. This is why our skin starts to sweat and why plants dry out in the heat. Even materials that are ...
As automobile electrification speeds up, the world faces an overwhelming need for critical metals and minerals to make atmosphere-saving electric vehicles possible.
Different cell types—say, heart, liver, blood, and sperm cells—possess characteristics that help them carry out their unique jobs in the body. In general, those characteristics are hard-wired. Without...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Regional inequality in China during its rise as a giant exporter: A value chain analysis
中国 出口大国 区域不平等 价值链分析
2023/4/27
China's exports success has implications for regional income inequality, because most of its export products are manufactured in the coastal zone. We propose a value chain-based accounting framework t...
Last year, MIT researchers announced that they had built “liquid” neural networks, inspired by the brains of small species: a class of flexible, robust machine learning models that learn on the job an...
When glacial ice sheets melt, something counterintuitive happens to sea levels. Logic might suggest that nearby levels would rise, but instead they fall.
As water restrictions tighten in Southern California in anticipation of summer, the Southwestern United States is seeing growing evidence of climate change and drought for millions of western resident...
