Scientists on Tuesday completed the first drilling task of an expedition to the South China Sea. The hole, identified as U1499A, has reached 3,770 meters below sea level, for collection of sediment samples. According to Sun Zhen of the Chinese Academy of Sciences South China Sea Institute of Oceanology, a preliminary lithologic study was conducted on sediment believed to have been formed eight million years ago.

As for issue of renewable sources, say, solar energy, its efficient conversion and storage has puzzled scientists for years. Recently, a study team reported their success in using a di-functional nanocomposite film to realize efficient conversion and storage of solar thermal energy. Meanwhile, in the study, a new mechanism for solar-to-heat conversion by utilizing surface plasmon resonance and subsequent thermal storage was proposed and demonstrated by modeling, announced the team led by Prof. WANG Zhenyang at Institute of Intelligent Machines, Hefei Institutes of Physical Science.

Recently, research has focused on the BiFeO3 (BFO) and Sr-doped LaMnO3 heterostructure for a series of novel physical properties that originate from the antiferromagnetic (AFM) and ferromagnetic (FM) exchange interaction across the heterointerface. In an article recently published in SCIENCE CHINA Physics, Mechanics & Astronomy, researchers at the Institute of Physics, Chinese Academy of Sciences, reported their investigation on the ultrafast laser-excited magnetization dynamics of ferromagnetic (FM) La0.67Sr0.33MnO3 (LSMO) thin films with epitaxial grown BiFeO3 (BFO) coating layers.

A novel refractive index sensor design based on the integration of microfluidic channel into metamaterial absorber is proposed by Professor CHEN Qin's research group at Suzhou Institute of Nano-Tech and Nano-Bionics of Chinese Academy of Sciences. Based on resonant field rather than the usual evanescent wave, sensitivity as high as 3.5 THz/RIU can be achieved in the frequency range of 4-9 THz. This study was published in Laser & Photonics Reviews.
Chinese scientists discovered five new species of plants in Yarlung Zangbo Grand Canyon in Tibet.
China is also looking beyond our solar system in playing a role in the search for life in space as we just mentioned the FAST radio telescope in Guizhou.
This clip shows testing of high speed train technology in the laboratory of the Institute of Mechanics at the Chinese Academy of Sciences in Beijing. The experimental platform is 274 meters long, the world's largest platform of its kind to conduct tests and experiments on aerodynamics of high speed trains traveling at 500 kilometers per hour. Check the video to experience a train being tested at 250 km per hour along the experiment platform. How fast can China's high speed train go?
