Chinese scientists have completed making a detailed genome map of giant panda, according to the State Forestry Administration. This year's research result showed that the giant panda has 21 pairs of chromosome, and genome size is 2.4 G, with repeated sequence content of 36 percent and more than 20,000 genes.
Ostrich eggshell (OES) beads from SDG site reflect primordial art and a kind of symbolic behavior of modern humans. Two different manufacturing pathways are usually used in the manufacture of OES beads in Upper Paleolithic. Pathway 1 is identified from these collections; blanks are drilled prior to being trimmed to rough discs. Based on stratigraphic data and OSL dating, these ostrich eggshell beads are probably in Early Holocene (10 ka BP).
Prof. XIAO Guoqing, the director of IMP (Institute of Modern Physics), CAS, visited the United States with CAS delegation from Nov. 11 to 20, 2009. The CAS delegation visited Argonne National Lab, Oak Ridge National Lab, Lawrence Berkeley National Lab, SLAC, Michigan State University (MSU), and Santa Cruz Astronomy Observatory at University of California.
The Chinese Academy of Sciences and Inspur Group have started a joint project to develop the third-generation genome sequencing instrument, which might slash the cost of genome sequencing by 99 percent. The instrument is expected to sequence a person's genomes in an hour at a cost of about 1,000 U.S. dollars, compared with six weeks and 60,000-100,000 dollars by the current second-generation instrument, said Yu Jun, deputy head of the Beijing Institute of Genomics with the Chinese Academy of Sciences.
Recent paleontological and neontological studies on feathers and feather-like integumentary structures have improved greatly our understanding of the origin and early evolution of feathers. New observations on some non-avian dinosaur specimens preserving integumentary structures, in combination with recent paleontological and neontological data, provide additional insights into this important evolutionary issue.
Zhores Ivanovich Alferov, the inventor of the heterotransistor and the winner of 2000 Nobel Prize in Physics, visited Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP) on Nov. 24th, 2009. MA Mingya, vice president of CIOMP, introduced to academician Alferov CIOMP's development concept and primary research work. He emphasized the importance of conducting international cooperation and reviewed the cooperations between CIOMP and institutes of Russian Academy of Sciences (RAS) over the last 20 years.
