Recently, researchers from the University of Science and Technology of China (USTC) reveals that not all forms of quantum nonlocality guarantee intrinsic randomness. They demonstrated that violating two-input Bell inequalities is both necessary and sufficient for certifying randomness, but this equivalence breaks down in scenarios involving multiple inputs. This finding has been published in Physical Review Letters

A research team led by Prof. SHI Long and Prof. ZHANG Heping from the University of Science and Technology of China (USTC) of Chinese Academy of Sciences (CAS) established the most comprehensive city-level fire incident database to date, covering 20.6% of the global population and quantified the intrinsic link between climate change and urban fire risks. The study was published in Nature Cities.

Here, researchers from Nanjing University of Aeronautics and Astronautics propose to control thermal stress at coating interfaces during laser induction processes and demonstrate a novel process for precisely graphenizing ultra-thin diamond coating surface through laser induction and mechanical cleavage, without damaging the substrates.

Their work provides an effective and cost-efficient avenue to overcome application bottlenecks in engineered diamond surfaces, expanding their use in friction pairs such as cutting tools, bearings, and mechanical seals. Moreover, it may facilitate advancements in multicarbon heterostructures and their preparation methods, supporting potential applications in electronics, aviation, and biomedicine involving diamond, graphene, and all-carbon devices.

A landmark five-year clinical study has revealed that spectacle lenses equipped with highly aspherical lenslets (HAL) can significantly slow the progression of myopia and axial elongation in children. 

Professors Zhaoyang Zeng and Can Guo from the Xiangya School of Basic Medical Sciences, Central South University, in collaboration with Researcher Wenjia Guo from Xinjiang Medical University, have discovered a novel circular RNA, circTP63-N, encoded by the TP63 gene, which suppresses the malignant progression of nasopharyngeal carcinoma. This significant finding has been recently published in Science China Life Sciences.
