Archaeologists discovered a series of important clues to ancient human activities in northwest Yunnan
On December 27, the Yunnan Provincial Institute of Cultural Relics and Archeology passed a joint scientific investigation in 2022. Archaeologists discovered a series of important clues to ancient human activities in northwest Yunnan. According to reports, the northwest Yunnan region is located in the southeastern part of the Qinghai-Tibet Plateau. The landforms in the region are complex and diverse, and the regional and vertical changes in climate environment are significant. It has long been a key area for research on geological structures, landform evolution, ecological environment, and biological diversity. In addition, the north-south mountains and rivers develop in the region, forming a channel effect on the natural geography of the country. It has become an important geographical corridor for human migration and exchange since ancient times. However, compared with the archaeological work and results that have been carried out in other areas of the Qinghai-Tibet Plateau, the research on the history of human activities in the Paleolithic Age in northwest Yunnan is relatively lagging behind, and the attention and display are very limited.
Six satellites of the "Jilin-1" satellite went on the expedition
On December 27, Changguang Satellite Technology Co., Ltd. launched six satellites. They will be launched from the Taiyuan Satellite Launch Center in China in the near future. After successful launch, they can provide remote sensing data and product services for agriculture, forestry, meteorology, oceans, urban construction, scientific experiments and other fields. Changguang Satellite is China's first commercial remote sensing satellite company. In 2015, its independently developed "Jilin-1" satellite was successfully launched, opening the curtain of China's commercial aerospace industry. The goal of the "Jilin-1" satellite constellation is to achieve a network of 300 satellites by 2025.
The world's largest liquid mirror telescope has begun to look up at the starry sky
According to a recent report on the British "New Scientist" magazine website, the 4-meter-diameter "International Liquid Mirror Telescope" (ILMT) located in the Himalayas has opened its "eyes" and looks into the depths of the universe. It uses a slowly rotating liquid mercury disk instead of a solid mirror to focus light for observations. Liquid mirror telescopes are much cheaper to build than traditional telescopes and have other unique advantages. If ILMT is successful, a larger liquid mirror telescope may be placed on the moon in the future to help get a glimpse of the "look" of the first star in the universe.
Bi Yong was elected as a foreign academician of the Russian Academy of Engineering. He once used "real laser" technology on the Winter Olympics stage.

Recently, Bi Yong, a researcher at the Institute of Physics and Chemistry Technology of the Chinese Academy of Sciences, was elected as a foreign academician of the Russian Academy of Engineering for his contribution to laser technology and application research, especially in the field of laser display technology research and industrialization.
New software uses DNA to create 3D nanostructures
According to the latest issue of Science Advances magazine, researchers from Duke University and Arizona State University The newly developed open source software program allows users to draw drawings or digital models of circles and convert them into 3D structures made of DNA. Each 3D structure is a tiny hollow body with a diameter of no more than 5 millionths of a centimeter. More than 50,000 of these microstructures can be accommodated on a needle.
Turbulence simulation reveals the flow of energy in plasma
Beijing On December 27, researchers from the Princeton Plasma Physics Laboratory of the U.S. Department of Energy discovered a solar corona heating process, which helps explain why the atmosphere surrounding the sun, the corona, is much hotter than the sun's surface. The discovery could improve the ability to solve a range of astrophysics puzzles, such as star formation, the origin of massive magnetic fields in the universe, and the ability to predict space weather events that could disrupt cell phone service and black out Earth's power grid. The breakthrough is detailed in the latest issue of the journal Science Advances.
