The study, published in Nature, introduced a three-dimensional optical fibre gripper that can manipulate opaque particles, irregular micromechanical components and diverse single-cell types. By controlling light input, the microgripper can open, close and adjust its gripping force. Experiments showed it can generate forces more than 100,000 times greater than conventional optical tweezers, enabling high-precision manipulation, microstructure assembly and microscale sampling.
The discovery, led by Professors Sun Daoyuan and Mao Zhu from the University of Science and Technology of China, was based on in-depth analysis of seismic data recorded by NASA’s InSight lander. Their study found that Mars harbours a solid core with a radius of about 600 kilometres.
In the 1930s, physicists discovered superfluidity in liquid helium, a major milestone in advancing foundational research in quantum physics. This discovery spurred the development of low-temperature technologies, including laser cooling and dilution refrigeration, which have become critical tools in quantum simulation, quantum computing, and related disciplines.
This finding, titled “Counterflow superfluidity in a two-component Mott insulator,” was published in the internationally renowned academic journal Nature Physics on Wednesday.
Praised by reviewers, the work was described it as an “outstanding achievement in the field of quantum simulation.”
Visitors view back-scatter electron micrographs of lunar soil particles at an exhibition themed on lunar soil research achievements in University of Science and Technology of China, in Hefei, east China’s Anhui Province, April 19, 2023. The exhibition starting Monday displays exhibits made by scientists, artists and engineers based on micrographs of lunar soil particles brought back by the Chang’e-5 probe.
