Foundation of Biophysics and Establishment of Interdisciplinary Subjects in China

As a new independent subject, biophysics emerged in the early 1950's. The Institute of Biophysics, Chinese Academy of Sciences, was established in 1958. It was the milestone of the beginning of biophysics in China. This review introduces the foundation and the early development of biophysics in China, and the establishment of the interdisciplinary subjects, including radiation biology, bio-cybernetics, astrobiology, and bionics.

PRELIMINARY BIOGEOCHEMICAL DATA ON MICROBIAL CARBONATOGENESIS IN ANCIENT EXTREME ENVIRONMENTS (KESS-KESS MOUNDS, MOROCCO)

The Devonian Kess-Kess mounds, cropping out in the Hamar Laghdad Ridge (SE Morocco), provide a useful case-study for understanding the relationships between the microbial metabolic activities and micrite precipitation in an extreme environment. Very fine dark and white wrinkled laminae record microbial activity and the geochemistry of the organic matter allows the characterization of the source organisms. The biogeochemical characterization of extracted organic matter was performed through the functional group analyses by FT-IR Spectroscopy. FT-IR parameters indicate a marine origin and low thermal evolution for the organic material. The organic matter is characterized by the presence of stretching ?C=C vibrations attributable to alkene and/or unsaturated carboxylic acids. Preliminary analysis with GC-MS provides evidence for an autochthonous (<C22) organic matter source for the free carboxylic acids. The origin of short-chain fatty acids that have a marked even over odd C number predominance is attributable to bacteria and/or algae and they are similar to those recorded in recent (Black Sea) and ancient (Late Jurassic to Early Cretaceous) methane-seep microbialites. These biogeochemical signatures of microbial carbonate precipitation in an ancient extreme environment may have implications in astrobiological research considering the recent discovery of carbonate deposits on Mars.

Examining claims of scientists from Aristotle to Hawking, the author traces the cascading influence of speculation about the existence of civilized life on other planets.

RESEARCH ADVANCES IN HYDROTHERMAL VENT MICROBIAL COMMUNITIES AND ITS SIGNIFICANCE FOR GEOLOGY

Hydrothermal communities in deep seafloor live around Black Smoker sites. The primary producers of hydrothermal ecosystems are thermophiles and archaea. Bacteria convert chemicals (from the sulfur-rich fluid spewed out of vents) to energy, in a process called chemosynthesis. They get energy depending on the oxidation of sulfides (H2S, FeS2) and methane and the reduction of carbon dioxide, instead of photosynthesis. There are two kinds of relationship between thermophiles and other animals. Other animals eat thermophiles or thermophiles exist in a symbiotic relationship with vent animals. Thermophiles not only depend on the deep-sea hydrothermal activities, but also play an important role of hydrothermal mineralization. The source of them is likely to be subsurface biosphere. Black smokers could be “windows to a deep biosphere”, which has crucial implication for the research of thermophiles and the understanding of astrobiology and the origin of life.
