Scientists Reveal Evolutionary History of Vertebrate Interferon Regulatory Factor[Feb 07, 2018]

To study the phylogeny and functional diversity of IRF gains the knowledge about the gene itself and may provide new insight into the evolution of immune system. The researchers at Institute of Hydrobiology of Chinese Academy of Sciences sequenced the genomes and transcriptomes of some ancient fish and lamprey, with a good insight into the vertebrate ancient genome, facilitating IRF study.

Researchers Analyze Spatial Variations and Sources of Trace Elements in Glaciers on the Tibetan Plateau[Feb 07, 2018]

Recently, scientists from the Northwest Institute of Eco-Environment and Resources of the Chinese Academy of Sciences investigated the potential sources and regional difference in the transport of trace elements over the Tibetan Plateau, and evaluated whether these regions were affected by human activities and the degree of pollution of trace elements.

Main Structure at LHAASO Water Cherenkov Detector Array Completed[Feb 07, 2018]

The main structure of the No.1 Pool of the Water Cherenkov Detector Array (WCDA) of the Large High Altitude Air Shower Observatory (LHAASO) was completed on February 1, 2018. In the next phase, scientists and engineers will start to install cosmic ray detectors inside the pool. It is estimated that construction will be completed and operation of this detector pool started by the end of this year.

Chemical Camouflage Is Decisive in Shaping Ant-treehopper and Fig-fig Wasp Mutualism[Feb 07, 2018]

Researchers from Xishuangbanna Tropical Botanical Garden (XTBG) and their cooperators used a weaver ant-treehopper mutualism associated with the fig tree species Ficus racemosa in southwestern China to test if the behaviors of the ants are affected by chemical signals given by treehopper mutualisms.


Scientists Probe Arsenic Cycle and Bioconversion in Terrestrial Ecosystems[Feb 07, 2018]

A research group led by Prof. WEI Chaoyang from the Institute of Geographic Sciences and Natural Resources Research has enhanced the basic knowledge on arsenic cycle and bioconversion in terrestrial ecosystems. They found a clue that some lower grade of organic arsenic like methylated forms can be converted to higher grade organic arsenic like arsenobetaine by earthworms in their bodies.

New Optical Imaging Strategy to Reveal the Fate of Transplanted Stem Cells[Feb 07, 2018]

Recently, Prof. WANG Qiangbin's group at Suzhou Institute of Nano-Tech and Nano-Bionics of Chinese Academy of Sciences developed a dual-labeling strategy to in situ visualize the fate of transplanted stem cells in vivo by combining the exogeneous near-infrared fluorescence imaging of Ag2S quantum dots and endogenous bioluminescence imaging (BLI) of red-emitting firefly luciferase.
