Plastid Phylogenomics Provides Insights into the Phylogeny and Isomeric Plastomes in Cupressoideae (Cupressaceae)[Apr 28, 2017]

Prof. YI Tingshuang's group and Prof. LI Dezhu’s group from Kunming Institute of Botany, Chinese Academy of Sciences (KIB/CAS), together with Prof. Shu-Miaw CHAW’s group from Biodiversity Research Center, Academia Sinica (BRCAS) reconstructed phylogenetic relationships of Cupressoideae and discussed plastome evolution based on 22 plastomes.

Stable and High Order Method Realizes Reverse Time Migration in Irregular Regions[Apr 28, 2017]

In irregular regions, to realize the acoustic wavefield simulation and reverse time migration, researchers recently extends the second order summation-by-parts finite difference method to the fourth order case. The fourth order accuracy finite difference scheme is known advantageous in reducing memory and improving efficiency.

Researchers Reveal a Complex Pattern of the Evolution and Emergence of H5N6 Avian Influenza Virus in central China[Apr 28, 2017]

In order to further understand the evolutionary behavior of H5N6 prior to its emergence in humans, the research group led by Prof. CUI Jie from Wuhan Institute of Virology of the Chinese Academy of Sciences developed the studies on the evolution and emergence of H5N6 avian influenza virus in central China.

Scientists Find Real-time Evidence of Morphological Changes of Dust Particles due to Internally Mixing with Pollution[Apr 27, 2017]

Scientists investigate polarization of oscillation direction of back-scattering signal of single dust particles online, based on a newly developed, bench-top optical particle counter. A real-time decrease in Asian dust depolarization was observed in North China for the first time.

Near-atomic Structure of Japanese Encephalitis Virus Reveals Critical Determinants of Virulence and Stability[Apr 27, 2017]

Professor RAO Zihe and Professor WANG Xiangxi from the Institute of Biophysics (IBP) of the Chinese Academy of Sciences, in cooperation with Professor QIN Chengfeng from the Beijing Institute of Microbiology and Epidemiology and Professor David Stuart in Oxford University and colleagues applied cryo-electron microscopy to determine the cryo-EM structure of mature JEV at near-atomic resolution.

Feeling the Heat—Changes in the Human Perception of Temperature over China in Recent Decades[Apr 27, 2017]

How has thermal comfort changed in recent decades over China against the background of the global warming? Scientists carried out an investigation over mainland China using the index of effective temperature (ET), which combines the effects of temperature, humidity and wind speed. The human perception of temperature was classified on a scale based on the values of the ET index, ranging from very cold, cold, cool, comfortable, to warm, hot, and very hot.
