High-resolution VLBI Images Reveal Radio Structure of A Quasar Shinning in the Early Universe[Mar 24, 2017]

High-redshift quasars (HRQs) are important for cosmology and galaxy studies. Recently, an international research group led by Prof. AN Tao from Shanghai Astronomical Observatory (SHAO) of Chinese Academy of Sciences has studied radio-loud HRQs, and found one promising target CGRaBS J0906+6930 (hereafter J0906+6930) in the early Universe.

Scientists Reveal Mechanism of Delivery of Secretory Proteins During Verticillium dahliae Infection[Mar 24, 2017]

Verticillium dahliae (V. dahliae) is a soil-borne, root-infecting fungal pathogen that causes severely wilt disease and leads to serious economic loss worldwide. Dr. GUO Huishan's group at the State Key Laboratory of Plant Genomics, Institute of Microbiology of Chinese Academy of Sciences, provided for the first time the mechanism of the delivery of secretory proteins by V. dahliae during plant root infection.

China Breaks Records in Mariana Trench[Mar 24, 2017]

Chinese scientists have broken two world records this year at the ocean's lowest depth - the Mariana Trench. The trench is about 2,550 kilometers (1,580 miles) long and around 69 kilometers (43 miles) wide. It reaches a maximum-known depth of 10,994 meters (36,070 feet) – which is more than Mount Everest at 8,850 meters.

Scientists Reveal the Strain Effect in Electrochemical Reduction of CO2[Mar 23, 2017]

Researchers from University of Science and Technology of China of Chinese Academy of Sciences revealed the strain effect in electrochemical reduction of CO2. By using Pd octahedra and icosahedra as a well-defined platform, they demonstrated the internal correlation between surface strain and catalytic performance in the electrochemical reduction of CO2.

Scientists Develop Single-longitudinal-mode Pulsed Fiber Lasers with Very Narrow Linewidth[Mar 23, 2017]

In a paper published in the journal of IEEE Photonics Journal, a study team led by Prof. MAO Qinghe in Anhui Institute of Optics and Fine Mechanics (AIOFM), Hefei Institutes of Physical Science obtains highly stable mode-hopping-free single-longitudinal-mode (SLM) Q-switched laser pulses with the linewidth of only 1.5MHz, which may be the narrowest linewidth for a Q-switched fiber laser so far.

SERS Helps to Evaluate DHA Effect on Cancer Cells[Mar 23, 2017]

In a paper published in Lab on a Chip, Chinese researchers announced using Surface-enhanced Raman spectroscopy (SERS) in a microfluidic chip they managed to develop a novel method to efficiently evaluate the effect of DHA on a single cell, said the research group led by Prof. Huang Qing at Institute of Technical Biology & Agriculture Engineering, Hefei Institutes of Physical Science.
