Scientists Rediscover Sun Bear in Yunnan, China[Jul 17, 2017]

In the evening of October 23, 2016, a short video footage of sun bear (Helarctos malayanus) was recorded in Yingjiang County, Yunnan Province, China. This precious video is the first recorded image of the species in China, strongly supporting the distributions of sun bear in China. This study, conducted by researchers from Kunming Institute of Zoology of Chinese Academy of Sciences, is recently published online in Zoological Research.

An Insulation-based Strategy Enables Precise Design of Genetic Circuits[Jul 17, 2017]

A research group led by Prof. LOU Chunbo at Institute of Microbiology of Chinese Academy of Sciences developed an insulate design principle adapted to prokaryotic transcriptional element. The principle realized the functional decoupling of promoters and operators in transcriptional control and enabled genetic circuit design with extraordinary precision and diversity.

Regional EEA Variation Can be Well Explained by Soil Properties in the Karst Regions[Jul 14, 2017]

Recently, Dr. CHEN Hao and his team from the Institute of Subtropical Agriculture collected the soil samples from secondary forest, shrubland, grassland and cropland underlain by either dolomite or limestone and assyed the activities of 7 soil extracellular enzymes related to carbon, nitrogen and phosphorus cycling in a regional- scale karst area, southwest.

The Otubain-like Protease WTG1 Regulates Grain Size and Shape in Rice[Jul 03, 2017]

A recent study by Dr. LI Yunhai's group at the Institute of Genetics and Developmental Biology, Chinese Academy of Sciences, in collaboration with Dr. Wang Dekai at Zhejiang Academy of Agricultural Sciences, isolated a wide and thick grain 1 (wtg1-1) mutant and identified the WTG1 gene, revealed a novel otubain-like protease WTG1 that regulates grain size and shape in rice.

Thermal Spin Current Induced by Edge Co-doping and Asymmetric Hydrogenation in 2D Materials[Jul 17, 2017]

Recently, a research group led by Prof. ZHENG Xiaohong at Institute of Solid State Physics, Hefei Institutes of Physical Science has made new progress in the study of thermally induced spin current in two-dimensional (2D) materials by edge co-doping and asymmetric hydrogen-terminations.

Scientists Reveal Global 3D Chromatin Structure Reprogramming from Mammalian Gametes to Early Embryos[Jul 14, 2017]

Dr. LIU Jiang's lab from Beijing Institute of Genomics (BIG) of Chinese Academy of Sciences and collaborators revealed the global reprogramming of 3D chromatin structures from mammalian gametes to early embryos. This study provided valuable data resources for the study of mammalian embryonic development.
