The Isotope Laboratory of Gansu Province, which centers on isotopes and related technologies, was officially established on January 20th in Lanzhou of China's Northwest Province Gansu. The laboratory will focus on cutting-edge research on the synthesis of superheavy elements and the island of stability, development and demonstration of isotope technologies.

A research team from Hefei Institutes of Physical Science designed a direct Z-scheme ZnS/Co9S8 heterojunction with hollow cubic structures, and the PEC sensor based on such materials achieved the highly sensitive and selective detection of chlorpyrifos through the inhibition to the photoresponse of ZnS/Co<sub>9</sub>S<sub>8</sub> by chlorpyrifos.
In a recent study, researchers from Xishuangbanna Tropical Botanical Garden (XTBG) reported well preserved fossil seeds of Apocynaceae from the Lower Eocene Niubao Formation in the central Qinghai Tibetan plateau (QTP), including a new genus, <i>Asclepiadospermum</i>, and two new species, <i>A. marginatum</i> and <i>A. ellipticum</i>.
Recently, a Chinese research team from Hefei Institutes of Physical Science reported the synthesis of graphene quantum dots (GQDs) under an external high magnetic field (HMF) and their applications in photothermal therapy (PTT). By introducing HMF during the preparation of GQDs, the joint team used phenol molecules as single precursors and hydrogen peroxide as oxidant, and the resulting 9T-GQDs were expected to possess strong absorbance in NIR-II region for improvement of their applications in PTT.
Recently, an underwater gliding snake-like robot (UGSR), which combines the characteristics of an underwater glider and an underwater snake-like robot, is proposed by Shenyang Institute of Automation of the Chinese Academy of Sciences. The robot can realize gliding motion driven by net buoyancy and multiple swimming gaits driven by joint torque, showing the advantages of strong endurance and good maneuverability.
The Chinese Academy of Sciences (CAS), China's highest academic institution in natural sciences, revealed its annual "Highlight Researches" list Sunday. Gene-edited diseased monkeys cloning, an archaeological discovery of the earliest human occupation of the Qinghai-Tibet Plateau and the unveiling of the African swine fever virus structure are the top three research advances in 2019.
Chinese scientists have developed an octopus-inspired soft robot with the capabilities of shrinking, environment-adaptive camouflage and multimodal locomotion. The robot possesses outstanding obstacle-crossing abilities including crawling within a two-mm-high tunnel and swimming through a 450-micrometer-wide channel, said DU Xuemin, the leading researcher.
Chinese researchers have discovered an important pathogenic mechanism of Mycobacterium tuberculosis infection, gaining a better understanding of how the bacterium causes disease. They made the discovery by identifying a previously unrecognized mechanism that Mycobacterium tuberculosis uses to suppress host immunity. A paper on the finding has been published on the website of the science journal <EM>Nature</EM>.
