Researchers Discover New Triply Degenerate Semimetal Candidate[Sep 18, 2018]

Topological semimetals hold exotic magneto transport properties (large magneto resistance, chiral anomaly, etc) and ultrahigh mobility, which makes them of great value on future application of low-energy electronics devices, so it has been one of the frontier and hot research field of the condensed matter physics. Researchers at High Magnetic Field Laboratory, Chinese Academy of Sciences discovered a new triply degenerate semimetal candidate, trigonal layered PtBi2 under high magnetic field of 40 tesla.

Rubber-flemingia macrophylla Systems Reduce Release of Soil Exchangeable Cations[Sep 17, 2018]

The degree of soil acidification in differently aged rubber plantations may differ, and the response of soil exchangeable cations to the introduction of Flemingia macrophylla to differently aged rubber plantations is unknown. Researchers from Xishuangbanna Tropical Botanical Garden investigated the responses of soil water content and exchangeable cations in rubber and rubber-Flemingia macrophylla systems.


Fossils Reveal Diverse Mesozoic Pollinating Lacewings[Sep 17, 2018]

A research group led by Prof. WANG Bo from the Nanjing Institute of Geology and Palaeontology has provided new insight into the niche diversity, chemical communication, and defense mechanisms of Mesozoic pollinating insects. They reported 27 well-preserved kalligrammatids from late Cretaceous Burmese amber (99 Ma) and Chinese Early Cretaceous (125 Ma) and Middle Jurassic (165 Ma) compression rocks.


Scientists Engineer Synthetic Methylotrophs for Methanol-dependent Growth and Amino Acid Production[Sep 17, 2018]

A research team led by Prof. ZHENG Ping and Prof. SUN Jibin at the Tianjin Institute of Industrial Biotechnology designed and experimentally engineered the industrial workhorse Corynebacterium glutamicum to serve as a methanol-dependent synthetic methylotroph for methanol bioconversion to amino acids.

Switch in the Climatic Factors Controlling Vegetation Dynamics on the Tibetan Plateau[Sep 17, 2018]

Using precipitation and temperature records along with Normalized Difference Vegetation Index (NDVI) data, Dr. HUA Ting and Prof. WANG Xunming analyzed the temporal and spatial variations in the relationship between factors controlling climate and vegetation dynamics over the Tibetan Plateau during the period 1982-2011.
