BEIJING, Jan. 11 (Xinhua) -- The following are the highlights of China's science news from the past week:

ALZHEIMER'S DRUG

An innovative Chinese Alzheimer's drug that hit the domestic market last week will go through clinical trials on 2,000 patients overseas in 2020.

The orally administered drug GV-971 will be tested in 200 clinical centers in North America, the European Union and other places, according to Green Valley Pharmaceutical Co., Ltd, one of the drug's co-developers.

SCI-TECH HUB

Beijing's Zhongguancun, known as China's "Silicon Valley," recorded a remarkable yearly increase of 13.8 percent in its revenue in the first 11 months of 2019.

According to the Beijing Municipal Bureau of Statistics, revenue from the science park's high-tech enterprises above a designated size exceeded 5.43 trillion yuan (around 780 billion U.S. dollars) in the January-November period.

AROMATIC PLANTS

Aromatic plants not only have a sweet smell but also a strong tolerance to cold weather. A new Chinese study found that adding a floral scent to tea plants may help them withstand low temperatures.

Cold weather is an environmental stress factor that limits the distribution, survival and growth of various plants. But the study published in the scientific journal New Phytologist says that increasing the concentration of aromatic substances in tea plants can enhance their resistance to cold temperatures.

SCI-TECH AWARD SYSTEM

China has improved its award system for scientific and technological achievements to spur innovation and foster high-quality development, according to the National Office for Science and Technology Awards.

China has enriched its national science and technology award system by setting up the State Preeminent Science and Technology Award, the State Natural Science Award, the State Technological Invention Award, the State Scientific and Technological Progress Award and the China International Science and Technology Cooperation Award.

MOUSE GUT MICROBIAL BIOBANK

Chinese researchers have built a mouse gut microbial biobank, according to a recent study paper published in journal Nature Communications.

Mice are widely used as experimental models for gut microbiome studies. The researchers from the Institute of Microbiology under the Chinese Academy of Sciences constructed the biobank comprising 244 strains representing 126 species of mouse gut microbes.

The biobank will provide resources for studies of gut microbiome functions associated with health and diseases. Enditem
