Scientists Identify Receptor Mimic Neutralizing Mechanism Against Hepatitis A Virus Infection[Jan 17, 2017]

Using cryo-electron microscopy, an international group of scientists have reported a potent HAV-specific neutralizing monoclonal antibody R10 that blocks receptor attachment and interferes viral uncoating. High resolution cryo-EM structures of hepatitis A virus (HAV) full and empty particles and of the complex of HAV with R10 Fab reveal the atomic details of antibody binding and point to a receptor recognition site at the pentamer interface.

Medical Diagnosis on Paper: Conducting SPME with Filter Paper[Jan 17, 2017]

Scientists have experimented with a whole range of advanced materials for conducting solid-phase microextraction (SPME), including graphane, metal-organic frameworks and aromatic polymers. But now a team of Chinese scientists has shown that SPME can also be conducted using a far-from-advanced material: paper.

Sympatric Tree Species Have Divergent Adaptive Hydraulic Safety Strategies[Jan 17, 2017]

Researchers from Xishuangbanna Tropical Botanical Garden (XTBG) of the Chinese Academy of Sciences investigated leaf and stem hydraulic properties as well as seasonal variations in water potential and stomatal conductance in three sympatric tree species of Anacardiaceae (evergreen Pistacia weinmanniifolia, drought-deciduous Terminthia paniculata, and winter-deciduous Lannea coromandelica) in a Chinese savanna.

Dynamic Location Changes of Histone H2A Phosphorylation Essential for Plant Chromosome Orientation and Segregation[Jan 17, 2017]

Recently, Dr. HAN Fangpu's group at the Institute of Genetics and Developmental Biology (IGDB) of Chinese Academy of Sciences found the relationship between H2AThr133ph and CENH3 (A centromeric histone H3 variant) nucleosome in plants during cell division, and revealed the potential temporal and spatial regulation roles for H2A phosphorylation in chromosome segregation.

Main Agricultural Region Experiences Regional Climate Drought in Xinjiang[Jan 16, 2017]

Global climate change is triggering more droughts throughout the world, especially in developing countries. The north slope of Tianshan Mountain is the major agricultural region for China’s Xinjiang Province. Is it also suffering from the disaster aggravated by global warming? Some scientists from the Xinjiang Institute of Ecology and Geography (XIEG) hope to find an answer to this question through their study.

Water Tower of Central Asia Keeps Shrinking: Study[Jan 16, 2017]

Total water storage in Central Asia has been decreasing in the last half century due to accelerating glacier melting caused by global warming, a research led by professor CHEN Yaning from the Chinese Academy of Sciences’ Xinjiang Institute of Ecology and Geography in Urumqi found recently.
