Highlights of China's science and technology news
BEIJING, Jan. 27 (Xinhua) -- The following are the highlights of China's science and technology news in the past week:
-- China has cloned five monkeys from a gene-edited macaque with circadian rhythm disorders, the first time multiple monkeys have been cloned from a gene-edited monkey for biomedical research.
Researchers said that the advance means that a population of customized gene-edited monkey models with uniform genetic background will be available for biomedical research.
-- A preliminary investigation into the claimed "genetically edited babies" shows that Chinese researcher He Jiankui had defied government bans and conducted the research in the pursuit of personal fame and gain.
The investigation team of Guangdong Province announced that He had intentionally dodged supervision, raised funds and organized researchers on his own to carry out the human embryo gene-editing intended for reproduction, which is explicitly banned by relevant regulations.
-- A new study led by Chinese and American researchers has found that ocean heating in 2018 grew to a record high, surpassing 2017, which was the previous warmest year ever recorded.
Data shows that the upper 2,000 meters of the global ocean have warmed by an average of 0.13 degrees Celsius over the past 60 years.
-- Chinese researchers have found that women who have given birth have a higher chance of developing heart disease and strokes than the childless.
-- China launched two satellites for multispectral imaging on a Long March-11 rocket from the Jiuquan Satellite Launch Center in northwest China.
Loaded with a multi-spectral imager and an infrared camera, they will form a network with the 10 previously launched Jilin-1 satellites, providing remote sensing data and services for forestry, shipping and resource and environmental monitoring.
-- Chinese researchers have used a huge floating airship to conduct water vapor observation at an altitude of over 6,200 meters in Qinghai-Tibet Plateau, according to the Chinese Academy of Sciences (CAS).
This huge floating airship, named "Jimu No.1," has a volume of 2,300 cubic meters and contains 1,400 kilograms of helium. Its surface is made of composite fabric, and it can withstand low temperatures of minus 70 degrees Celsius.
-- Researchers from the Shanghai Institute of Biochemistry and Cell Biology of CAS suggested that patients with a fever higher than 38.5 degrees Celsius should take fever-reducing medicines after sustaining for about six hours. They explained that the fever could promote the protection mechanism of the human body in fighting against pathogen infection.
