Nitrogen Uptake Patterns Shift with Age of Rubber Trees[Apr 23, 2018]

Researchers from Xishuangbanna Tropical Botanical Garden (XTBG) conducted a study to examine how root uptake rates and preferences for organic and inorganic nitrogen forms change with plantation age. They selected rubber plantations of 7, 16, 24, 32 and 49 years of age in the same region with similar topography.

First Direct Observation of CH/CH van der Waals Interactions in Proteins[Apr 23, 2018]

The Protein Design Group led by Prof. YAO Lishan from the Qingdao Institute of Bioenergy and Bioprocess Technology developed a new Nuclear Magnetic Resonance (NMR) method to detect the J-coupling across the CH/CH van der Waals interaction between protein aliphatic side chain groups. For the first time, a quantitative analysis of van der Waals' interaction in proteins has been achieved.

How Metformin Delays Human Cellular Aging[Apr 20, 2018]

Recently, the effects of metformin on elongating lifespan have been demonstrated in some animal models. The researchers at the Institute of Biophysics of Chinese Academy of Sciences reported that chronic low-dose metformin treatment upregulates the endoplasmic reticulum-localized glutathione peroxidase 7 (GPx7) and delays aging in human cells.

Characterizing 'Keyhole' Is First Step to Fighting Obesity at Cellular Level[Apr 20, 2018]

An international team has uncovered the potential to beat obesity at the cellular level, characterizing for the first time a complex, little-understood receptor type that, when activated, shuts off hunger. Their findings are published online in Nature. The next step in this molecular-level research is target validation: proving that the receptor really does control hunger.

New Strategy to Transparent Yttrium Aluminum Garnet-based Nanoceramics[Apr 20, 2018]

A research team led by Prof. LI Jianqiang from the Institute of Process Engineering proposed the innovative idea of using solidification-amorphous crystallization method to prepare YAG transparent ceramics. They used the containerless solidification technique to suppress the nucleation of the high undercooling state of the melt.
