New Integrative Stratigraphy and Timescale for China Released[Jan 16, 2019]

A special issue, edited by Prof. SHEN Shuzhong and Prof. RONG Jiayu of the Nanjing Institute of Geology and Palaeontology, summarizes the latest advances in stratigraphy and timescale as well as discusses the correlation among different blocks in China and with international timescales.

Scientists Reveal the Multistep SFTSV Entry Process and the Dynamic Virus–host Interactions Involved[Jan 15, 2019]

In a joint study, the research groups from Huazhong University of Science and Technology and Wuhan Institute of Virology dissected the dynamic molecular process of SFTSV entry and penetration via quantum dot (QD)‐based single‐particle tracking and multicolor imaging. The researchers showed that SFTSV was internalized into the host cell via the recruitment of clathrin onto the plasma membrane for clathrin‐coated pit formation.

Novel Photonic Crystal Actuator Materials Developed[Jan 15, 2019]

Recently, Professor WANG Jingxia at Technical Institute of Physics and Chemistry, together with Professor CHEN Bo from Hunan Normal University have jointly developed a Janus-type poly (ionic liquid-methyl methacrylate) copolymer inverse opal PC film by gradient filling method. The upper surface of the actuator is a hydrophilic polyionic liquid, and the lower surface is enriched with hydrophobic polymethyl methacrylate.

Laser Empowers 3D Imaging Technique[Jan 10, 2019]

Recently, a research team led by Professor LIU Cheng from Key Laboratory of High Power Laser and Physics, Shanghai Institute of Optics and Fine Mechanics, has developed K-domain transform based 3D imaging technique. By simply illuminating a sample with a light sheet and rearranging the angular frequency components of the reflected light, this technique realizes the measurement of the inner 3D structure.

Scientists Reveal the Mechanism of A Human Monoclonal Antibody-mediated Neutralization against Yellow Fever Virus[Jan 15, 2019]

Recently, Yellow fever virus re-emerged in Africa and Brazil, leading to hundreds of deaths, with some cases imported to China. Prophylactic or therapeutic countermeasures are urgently needed. Previously, several human monoclonal antibodies against YFV were screened out by phage display. Here, scientists find that 5A exhibits high neutralizing potency and good protection. Crystallographic analysis of the YFV envelope (E) protein in its pre- and post-fusion states shows conformations similar to those observed in other E proteins of flaviviruses.

Single-mode Nanolasers of Superior Quality Factor Emerge from New Materials[Jan 08, 2019]

Recently, researchers from Shanghai Institute of Optics and Fine Mechanics of Chinese Academy of Sciences (CAS), Shanghai Institute of Technical Physics CAS, and Hunan University, demonstrated ultrahigh Q single-mode laser with much narrow linewidth and low threshold in CsPbBr3 perovskites with novel spherical and cubic structure.
