How Does Short-term Litter Input Manipulation Affect Soil Respiration and Its Carbon-isotopic Signature?[Feb 23, 2017]
Under the supervision of Prof. CHENG Xiaoli, WU Junjun from Wuhan Botanical Garden of the Chinese Academy of Sciences conducted a Detritus Input and Removal Treatment (DIRT) experiment in a coniferous forest (Platycladus orientalis (Linn.) Franco) ecosystem of central China to investigate the impact of above- and belowground litter input on soil respiration and its carbon isotope signature.
Scientists from Shanghai Institute of Materia Medica (SIMM) of Chinese Academy of Sciences made progress in discovering the role of the metabolic enzyme phosphoglycerate mutase 1 (PGAM1) in maintaining genomic stability, and found that PGAM1 inhibitors have the potential to expand the therapeutic benefits of FDA-approved ovarian cancer Olaparib (Lynparza) to a wider range of cancer types than currently indicated, such as triple-negative breast cancer. This study was published in The Journal of Cell Biology.
Researchers Find Insight into the Simplest Substitution Reaction via Walden Inversion Mechanism[Feb 22, 2017]
A research team led by Prof. ZHANG Donghui from State Key Laboratory of Molecular Reaction Dynamics, Dalian Institute of Chemical Physics has carried out an accurate quantum dynamics study of the H'+CH4→CH3H'+H substitution reaction and its isotope analogies.
Atom-scale Oxidation Mechanism of Nanoparticles Provides New Route for Anti-corrosion Materials Development[Feb 22, 2017]
The research group led by Prof. BAO Xinhe from Dalian Institute of Chemical Physics discovered that oxide nanostructures (NSs) with a diameter below 3 nm could exhibit an oxidation resistance much more superior than larger NSs. By investigating the oxidation mechanism at the atomic level, the team proposed, for the first time, a "dynamic size effect", that determines the stability of supported nanoparticles. These findings were published in the latest issue of Nature Communications, entitled “Enhanced oxidation resistance of active nanostructures via dynamic size effect”. This study not only brings the atomic understanding of the dynamic remodeling mechanism of nanocatalyst under the atmosphere, but also provides a new interface control for the development of anti-corrosion and anti-oxidation nano-protective coating.
Modeled Microgravity Could Affect Initiation of Radio-adaptive Response in Arabidopsis Thaliana[Feb 22, 2017]
A Chinese study team devised an experimental method through which they managed to reveal the effect of microgravity on radio-adaptive response in plants, reported in a paper published last week in Mutation Research / Fundamental and molecular mechanisms of mutagenesis.
Recently, due to the fact that antifreeze proteins (AFPs) protect a broad range of biological organisms inhabiting subzero environments, Prof. WANG Jianjun from Institute of Chemistry of Chinese Academy of Sciences (CAS), Prof. FANG Haiping and Dr. WANG Chunlei from Shanghai Institute of Applied Physics of CAS investigated the mechanism for how AFPs decrease freezing temperature and inhibit ice growth and recrystallization.
