A new study conducted by scientists in China and Germany, and published December 6 in the online, open-access journal PLoS Biology, now provides a possible explanation by showing that activity levels of genes in the human brain during development changed substantially compared to chimpanzees and macaques.
Ph.D candidate, XIA Houjun (Kunming Institute of Zoology, the CAS) and his colleagues have done series research on the dendritic cells (DCs) subsets’ population, immuno-phonotype, function and mechanisms of SIVmac239 infected Chinese rhesus macaques (Ch Rhs), which have added knowledge to what people have known about HIV.
When kissing your sweetest pet dogs, I guess most of you aware that they are from the domestication of wolfs. But when it comes to the origins the cute fur balls, I bet you get no clue. As may have been the first animal to be domesticated, to date, in which geographical region the domestication of wolf occurred is still quite controversial.
Ph.D candidate JI Yinqiu (Kunming Institute of Zoology, the CAS) and her colleagues investigated 14 nuclear markers (including 8 functional genes, 2 pseudogenes and 4 intergenic regions) from 11 different chromosomes in East Asia-wide samples and pooled them with previously obtained mtDNA data for a combined analysis.
The Kunming Institute of Zoology resequenced the genomes of 40 Asian cultivated rice accessions and 10 wild rice accessions in collaboration with CAS Institute of Botany, Berkley University and Cornell University. Researchers identified around 15 million candidate single nucleotide polymorphisms (SNPs) in all 50 accessions and obtained 6.5 million high-quality SNPs.
Drs. JIANG Shunxing and WANG Xiaolin from Institute of Vertebrate Paleontology and Paleoanthropology (IVPP), Chinese Academy of Sciences, described a new ctenochasmatid pterosaur, Pterofiltus qiui gen. et sp. nov., from the Lower Cretaceous deposits of Liaoning, China, as reported in Annals of the Brazilian Academy of Sciences.
