China will launch an international English journal called "Satellite Navigation," according to the China Science Daily Thursday. The journal is coordinated by the Aerospace Information Research Institute of the Chinese Academy of Sciences and the Springer Nature.

The new technology developed by Wuhan Botanical Garden, Chinese Academy of Sciences, allows water hyacinths to be controlled and shifted into organic fuel, according to Wang Qingfeng, deputy director of the garden. As a biogeochemist, Lucienne paid close attention to the new technology. "We have the same problems, water hyacinths damage our native plants and block the rivers with their rapid growth. I hope we will have the chance to cooperate with Wuhan Botanical Garden to limit the spread of invasive species," he said.

Chinese researchers have disclosed that the nitrogen and phosphorous interactions can promote uptake of both nutrients by plants. Nitrogen and phosphorus are two of the essential nutrient elements for plant growth. But how the interactions of the two elements differ among different terrestrial ecosystems remains unclear.

A new monitoring and early warning platform of algae blooms and lake flooding of Taihu Lake, one of the largest freshwater lakes in east China's Jiangsu Province, has started its test run, according to the Chinese Academy of Sciences (CAS).

A Sino-German team of scientists have invented a nano-ribbon aerogel material capable of maintaining super flexibility in a wide temperature range from minus 196 degrees Celsius to 1,000 degrees Celsius. The aerogel team is led by Zhang Xuetong, a researcher at the Suzhou Institute of Nanotechnology and Nano Bionics of the Chinese Academy of Sciences.

China's domestically developed smog-monitoring laser radar system has been deployed in many places to monitor air quality. The Hefei Institute of Physical Science of Chinese Academy of Sciences system passed inspection by the Ministry of Science and Technology, the Xinhua News Agency said on Friday.

Chinese researchers have discovered that a high density of metal cadmium in soil makes plants more sensitive to ozone pollution. Researchers from the Institute of Applied Ecology of the Chinese Academy of Sciences used the Urban Field Experiment Platform to conduct research on the effects of elevated ozone concentration and a high density of heavy metal on plants in northeast China.

Chinese research vessel Science left the eastern city of Qingdao Saturday, on an expedition to the little-known seamounts in the Mariana Trench, the world's deepest natural trench. Researchers will study the topography, hydrology and bioecology of the western Pacific Ocean's typical seamount, said Xu Kuidong, chief scientist of the mission with the Institute of Oceanology of the Chinese Academy of Sciences.

Chinese scientists have discovered the signature of bomb radiocarbon (C14) produced by thermonuclear tests in muscle tissues of shrimp taken from the world's deepest ocean trench. The research result indicates that anthropogenic pollution has reached the deepest place of the ocean via the food chain.

Researchers have discovered a new species of orchid in southwestern China's Tibet Autonomous Region and the finding has been published on a scientific journal. Growing on trees or mossy rocks near the riverside with an altitude of 1,700 to 2,000 meters, the orchid has conical pseudobulbs, ovate-oblong leaves, and ovate-rhomnus petals.
