BEIJING, June 12 (Xinhua) -- The following is a summary of published science and technology news of China.

METEOROLOGICAL SATELLITE TO DAWN-DUSK ORBIT

China plans to send a weather satellite into a dawn-dusk orbit, its developer said Thursday.

The satellite was designed and built by the Shanghai Academy of Spaceflight Technology, affiliated with the China Aerospace Science and Technology Corporation. It will be the world's first polar-orbiting weather satellite in a dawn-dusk orbit.

According to the academy, the satellite is undergoing final tests and is expected to come out of the factory by the end of 2020.

POTENTIAL RISKS OF ALIEN ANIMALS INVASION

Researchers warned that protected natural areas around the world should notice potential invasion risks from alien species, according to a recent research article published in the journal Nature Communications.

They investigated the invasion of 894 types of alien animals from 11 taxonomic groups across 199,957 protected areas worldwide and found that less than 10 percent of protected areas were invaded by alien species, while at least one wild, established population was observed within 10 to 100 km of the boundaries of 89.4 percent of the protected areas.

Among the protected areas, national parks had more invasive species, according to the research, and more than 95 percent of protected areas were environmentally suitable for the establishment of wild populations.

TURNING TOXIC BLUE ALGAE INTO PROTEIN POWDER

Chinese researchers have developed a technology to turn blue algae into protein powder with high detoxification efficiency.

A research team from the Research Institute for Environmental Innovation (Suzhou), Tsinghua, in east China's Jiangsu Province, used microsecond ultrasound to explode blue algae, which achieved detoxification with an efficiency of up to 99.8 percent.

Without any addition of chemical or biological reactants, only water vapor was used as the medium in the whole experimental detoxification process, resulting in zero emissions.

HIGH-PROTEIN CORN VARIETIES CULTIVATION PROGRAM

The Chinese Academy of Agricultural Sciences has launched a program to facilitate the breeding of high-protein corn varieties and promote the healthy development of animal husbandry.

To develop high-quality corn varieties as livestock feed, the program will focus on high-protein corns by creating germplasm resources, utilizing molecular-design breeding and evaluating nutritional value. It will also introduce cultivation demonstration projects and design new animal-feed formula. Enditem
