Due to the inherent low atomic number of organic materials, their ability to absorb high-energy rays is relatively weak. Coupled with the low utilization rate of excited-state excitons, the radio-luminescence intensity of organic scintillators is generally lower than that of inorganic scintillators. Recently, the research team led by Professor Shuang-Quan Zang from Zhengzhou university innovatively utilized charge-separated (CS) state traps to capture high-energy carriers, significantly enhancing the radio-luminescence intensity of organic scintillators. The related paper was published in National Science Review.

This work demonstrates a novel method of manipulating the QDs’ optical properties beyond controlling their size, composition or structure, and reveals great potential for achieving full-color emission using monodisperse QDs.

The South Atlantic Anomaly represents a region within near-Earth space characterized by a significantly weaker geomagnetic field and a higher flux of energetic particles compared to other areas. It is a space weather hazards to Low-Earth-Orbit satellites. There has been evidence that the Very Low Frequency (VLF) waves from the powerful ground VLF radio transmitter in Australia, known as NWC, have the capacity to scatter energetic electrons’ pitch angle in the inner radiation belt. In a paper published in Science China: Earth Sciences, scientists report the initial observation of a 'wisp' precipitation resulted from NWC, an unusual occurrence with peak intensity detected inside the SAA. With the full pitch angle distribution observed via the Macao Science Satellite – 1 at Low-Earth-Orbit, scientists attribute the 'wisp' within the anomaly to a specific pitch angle range just outside the drift loss cone.

This study achieved CRISPR/Cas9-mediated genome editing in grass carp (Ctenopharyngodon idella), China's most economically vital freshwater fish. Targeting the tyrb gene critical for pigmentation were performed. Mutations confirmed by sequencing caused a golden phenotype with melanophore reduction. Using multiple gRNAs enhanced mutation rates (88.9%) and triggered large DNA deletions. This successful gene editing in grass carp enables rapid creation of golden germplasm, addressing industry demands for improved aquaculture varieties.

Austrian researchers have successfully converted a by-product of wood gasification into high-quality activated carbon. The material, known for its ability to capture micropollutants, was produced by physical activation using hot gases that create fine pores. Their method increased the adsorption capacity by 11 times, outperforming commercial alternatives. With growing demand in water treatment, this discovery offers a renewable alternative to fossil-based activated carbon.

A research team has developed innovative photonic crystal designs that significantly improve laser performance by mitigating finite-size effects.

Iron-dependent ferroptosis, a non-apoptotic cell death mechanism, is gaining attention for its role in immune suppression. Ferroptosis, driven by excessive lipid peroxides and iron-dependent reactive oxygen species (ROS), differs from other cell death forms in its immunogenicity. It involves the regulation of the cystine/glutamate transport system xc−, with glutathione (GSH) and glutathione peroxidase 4 (GPX4) preventing toxic lipid peroxide accumulation. Ferroptosis-related factors are implicated in various diseases, including cancer and cardiovascular diseases.
