The 8.5-magnitude Haiyuan Earthquake that shook northwest China in 1920 killed about 273,400 people, over 40,000 more than previously estimated, a Chinese seismologist said Thursday. The epicenter of the quake was Haiyuan County, in Ningxia Hui Autonomous Region, but it also rocked neighboring Gansu and Shaanxi provinces, on Dec. 16, 1920.
One research discovery from Institute of Vertebrate Paleontology and Paleoanthropology (IVPP), Chinese Academy of Science, "Fossilized melanosomes and the colour of Cretaceous dinosaurs and birds”, developed by Drs. ZHANG Fucheng, ZHOU Zhonghe, XU Xing and WANG Xiaolin, and three other scientists from Britain and Ireland, were honored as the 64th of this year's top 100 science stories by Discover magazine.
Drs QIAO Tuo and ZHU Min, from Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences, recently described cranial morphology features of the stem-group sarcopterygian Guiyu oneiros including the dermal bone pattern and anatomical details of the ethmosphenoid, as reported in the latest issue of Scinece China.
An integrated circuit innovation park is now planned for the Zhongguancun area, famed as China's Silicon Valley. The Chinese Academy of Sciences will invest 1.25 billion yuan in the project that seeks to attract competitive companies and startups to foster proprietary intellectual property and innovative products.
"Numerous studies have synthesized mesoporous hollow silica nanomaterials and explored the possibility of using them as drug carriers," Fangqiong Tang, a professor of chemistry at the Laboratory of Controllable Preparation and Application of Nanomaterials, Technical Institute of Physics and Chemistry, Chinese Academy of Sciences, tells Nanowerk. "But most of this research has focused on in vitro experiments. Few results have been reported on their in vivo behavior and therapeutic efficacy."
"Nanorattles" consisting of a mesoporous shell and gold nanoparticle core can now be synthesized through a simple, efficient and controllable process. Rattle-type nanoparticles consist of a spherical shell encapsulating a freely moving core particle in solvent. Several rattle-type structures have been prepared in previous research, including some in which the core is a metal nanoparticle and the shell is a mesoporous material.
