Strain-engineered bacterial consortium drives fuel cell

A group at the Institute of Microbiology of CAS has described a novel microbial fuel cell. Genetically modified cyanobacteria assimilate CO2 in visible light to form D-lactic acid, which they cannot utilize and excrete into the medium. A second microorganism, Shewanella bacteria, oxidises the D-lactic acid and conducts the electrons formed via a membrane protein […]

Silk-based composite membrane designed for salinity-gradient power plants

“Osmosis power plants” could use the potential difference between salt water and fresh water, e.g. in the estuaries of large rivers, to generate electrical energy by reverse electrodialysis. Liping WEN and colleagues from the Institute for Physics and Chemistry at CAS in Beijing investigated suitable composite membranes for this purpose. They produced a nanoporous composite […]

More than 300 traditional medicinal plants recorded in the Wuliang Mountains, Yunnan

In the course of an ethnobotanical study, a team under CAI Chuantao as the principal investigator assessed the utilization of traditional medicinal plants by local people in Jingdong, Yunnan Province. The team from CAS Xishuangbanna Tropical Botanical Garden recorded a total of 302 traditional medicinal plant species belonging to 117 families and 252 genera. The local […]

Cybersecurity in China improves, but slowly

Acording to a talk at Beijing Cyber Security Conference, around 48.5 percent of China’s government agencies and 56.3 percent centrally-administered state-owned enterprises have deployed security operation centers, and the response time to security events has been reduced to less than one hour from about three days in 2016. In the first half of 2019, more […]

China’s R&D expenditure for basic science exceeded 100 billion RMB in 2018

According to the Statistical Bulletin on Annual Government R&D Expenditure (2018), China spent almost 2 trillion yuan on research and development (R&D) in 2018, up 11.8 percent year-on-year, of which 109.4 billion yuan ($15.2 billion) went to basic research. Universities and state-owned research institutions spent 59 and 42.3 billion ¥, respectively, whereas enterprises accounted for […]

China launches polar satellite

The satellite called “Ice Pathfinder” (Code: BNU-1) was developed and built by Aerospace Dongfanghong Development in Shenzhen weighs 16 kilograms and carries three experimental payloads-a multispectral camera, a high-resolution visible-light camera and an automatic identification system receiver, a device for ship identification. The satellite is tasked with observing and monitoring the climate and environment in […]
