Scientists found that human's energy expenditure had a maximum possible level of exertion that can sustain in the long term, no matter what the activity is. The study published on Wednesday in the journal Science Advances showed that humans can only burn at 2.5 times their rate of metabolism at rest or the basal metabolic rate, in the long run.

A total of 15 captive-bred Chinese crocodile lizards were released into the wild in south China's Guangxi Zhuang Autonomous Region last Friday, as scientists continue to monitor how the rare creatures are adapting.

Chinese researchers have developed a new and efficient fluorescent method to simultaneously detect a variety of malignant tumor markers. The new method was developed by a research team with the Suzhou Institute of Biomedical Engineering and Technology of the Chinese Academy of Sciences.

Kenya and Chinese researchers will cooperate in order to develop new tea varieties, the country's agricultural research agency said on Tuesday. A team of researchers from KALRO have also been invited by the Chinese Academy of Sciences to attend a tea conference in China later this month.

Chinese scientists have found a major lithium deposit in Southwest China's Yunnan Province, estimated to contain more than 5 million tons. A team led by research fellow Wen Hanjie from the Institute of Geochemistry under the Chinese Academy of Sciences found 340,000 tons of lithium oxide in a test site in central Yunnan.

China's National Supercomputing Center in the south China city of Shenzhen on Friday launched a testbed for artificial intelligence (AI) experiments. The AI testbed, named Tai, provides the basic environment of AI chips and systems for the research, development and application tests of AI inventions.

Chinese scientists demonstrated in a study that carbon dioxide could be a better fluid used in extracting resources like shale gas within rocks than water. The study showed that the replacement technique could pave way for a more effective and eco-friendly form of fracking while storing captured atmospheric carbon dioxide.

Chinese scientists have developed a method to inhibit the generation of toxic substances from waste incineration through uncovering the formation mechanism of dioxins. The research carried out by scientists of the Dalian Institute of Chemical Physics has led to the development of inhibition technologies which can reduce emissions of dioxins by more than half in solid waste incineration.

Chinese researchers from Kunming Institute of Zoology of the Chinese Academy of Sciences have found that the three major river valleys in China are significant forces involved in shaping the current genetic diversity of Han Chinese, the world's largest ethnic group.

Chinese scientists aboard research vessel KEXUE (Science) photographed several "seabed gardens" with colorful corals and sponges on Tuesday in a seamount of Mariana Trench, located in the western Pacific Ocean. The coral gardens were discovered in the east ridge of the seamount in the south of the Mariana Trench, the deepest place of the earth, by a remote operated vehicle (ROV).

Discovery, a remote operated vehicle (ROV) aboard China's research vessel KEXUE (Science), captured two rare deep-water sea slugs in western Pacific Ocean in a recent dive. Sea slugs are hardly seen in deep-water (deeper than 200 meters), but Discovery gathered the two at the depth of 970 meters, according to Xu Kuidong, chief scientist aboard the vessel and a researcher of the Chinese Academy of Sciences (CAS).

A Chinese institute has monitored the changes of an exotic plant invasion on China's coasts, with remote sensing technology. The Northeast Institute of Geography and Agroecology affiliated to the Chinese Academy of Sciences said the perennial grass had spread to 546 square km by 2015, nearly double that of 1990.

China's research vessel KEXUE (Science) on Monday started to explore a series of seamounts in the south of the Mariana Trench, the deepest place of the earth. The remote operated vehicle (ROV), Discovery, dived into the sea on Monday morning to collect videos, information and samples from a small seamount in the southwest of the targeted area.

Chinese scientists launched a giant aerostat, a helium-filled tethered balloon, called Jimu-1 on Thursday morning to observe atmospheric water vapor at a record altitude of 7,003 meters in the Namtso region of the Qinghai-Tibet Plateau. Unlike a blimp, which is powered and steerable in the air, Jimu-1 is essentially a supersized balloon with a volume of 2,300 cubic meters.

China has opened an online database of international camellia varieties, providing data support for horticulture and agriculture. The Database of International Camellia Register was developed by the Kunming Institute of Botany under the Chinese Academy of Sciences. It was supported by the International Camellia Society and international experts.

Chinese paleontologists have discovered more than 30 ancient human fossils that dated back to about 300,000 years, at an excavation site in Dongzhi County in east China's Anhui Province. They have also found more than 100 stone artifacts used by ancient humans as well as mammalian fossils of over 40 species.

Researchers from China's Yunnan University, Xishuangbanna Tropical Botanical Garden of the Chinese Academy of Sciences, and the University of Toronto in Canada studied the reproduction mechanism of hardy ginger (Cautleya gracilis).

Environment-related patent applications in China have surged over the past decade, Thursday's China Daily reported. The country ranked first globally in patent filings between 2008 and 2017, the newspaper cited a recent report as saying.
