●The 0.2-gram "rope" can lift objects weighing 5 kilograms, and the stretch length can reach 600%, and it is also very tough. Recently, Wang Meixiang, a postdoctoral fellow in dickkey Laboratory at North Carolina State University, published a paper in Nature Materials as the first author to introduce this new material. It is a type of ionic liquid gel, which has set the highest record for tensile properties and toughness of this material, and also shows a broader application prospect than hydrogels.

Recently, the research group of Professor Sun Daoyuan of the University of Science and Technology of China and Dan J. Bower of the University of Bern in Switzerland have made important progress in the study of the structure of large-scale ultra-low-speed anomalies at the boundary of the Earth's nuclear mantle, and obtained the three-dimensional structure of the largest scale ultra-low-speed zone found so far in the Pacific Ocean. The results were published in Nature Communications on February 24. (Source: Science and Technology Daily)
