Researcher Reveals Genetic Variatoin of Ca and Zn Accumulation in Apple[Mar 23, 2017]

In order to understand the genetic variation for Ca and Zn accumulation in apple fruit germplasm, LIAO Liao, supervised by Prof. HAN Yuepeng from Wuhan Botanical Garden of the Chinese Academy of Sciences, assessed Ca and Zn content in mature fruits of 417 apple germplasm.

Eastern Honey Bees Have Lower Antennal Responses and Less Attracted to Queen Mandibular Pheromone[Mar 22, 2017]

Prof. TAN Ken and his team of Xishuangbanna Tropical Botanical Garden (XTBG) of the Chinese Academy of Sciences conducted a study to compare the antennal responses and worker cluster (retinue) formation behaviors of eastern honey bee workers and western honey bee workers to identical presentations of major-component QMP blends and individual QMP components.

Beijing Severe Haze More Frequent under Global Warming[Mar 22, 2017]

Conducive weather conditions are an important ingredient of severe haze episodes, which feature reduced surface winter northerlies, weakened northwesterlies in the midtroposphere, and enhanced thermal stability of the lower atmosphere. While the priority to mitigate Beijing severe haze is to effectively reduce emissions of air pollutants, the global effort in reducing greenhouse gas emissions will contribute to decreasing the risk of Beijing winter severe haze events.

Scientists Reveal Bacterial Diversity Patterns in the Semi-arid and Arid Grassland of North China[Mar 22, 2017]

Based on this conceptual framework, Dr. WANG Xiaobo, a microbial ecologists in the Institute of Applied Ecology of the Chinese Academy of Sciences, conducted a 4,000 km transect survey in China's drylands across four different habitats including alpine grassland, desert, desert grassland and typical grassland. He collected 545 soil samples in total and compared systematically the differences in the distance-decay curves of bacterial communities (at both the 97 and 99% resolutions), and in the relative importance of underlying factors (environmental variables or geographic distance) contributing to such relationships.

Functional Circuits Regulate Activity of Serotonergic Neurons[Mar 22, 2017]

A recent study published in Cell Reports systematically analyzed the circuit mechanism underlying dynamic control of serotonergic neuron in the rodent brain. Dr. SUN Yangang's Lab at the Institute of Neuroscience of Chinese Academy of Sciences used adeno-associated virus (AAV) tracing and patch clamp recording combined with optogenetic method in brain slices to explore the functional inputs to serotonergic neurons, and uncovered organizing principles of long-range inputs to the serotonergic neurons.

A Novel Ubiquitin-dependent Pathway to Promote High-fidelity DNA Repair[Mar 21, 2017]

Unrepaired DNA damage contributes to mutations and genome instability, and may eventually cause cancers. Researchers at University of Science and Technology of China (USTC) of Chinese Academy of Sciences, The University of Hong Kong and other collaborators uncovered an ubiquitin-dependent pathway that promotes high-fidelity DNA repair.
