Although China’s bearing industry has developed rapidly for many years, it has now become the third largest bearing country in the world in terms of bearing output and sales, but the key technology areas still need to be strengthened, especially the gap between the aerospace bearing technology and the first bearing is obvious. 
It is speculated that hybrid ceramic bearings have been initially applied in the field of China’s new turbofan 15 aero engine and transmission.

• Scientist says it will be used to monitor solar activity and provide more accurate data to support research and space weather forecasting
• The world’s largest and most powerful – with a 4-metre aperture – is in Hawaii, and is expected to be ready for use in July https://www.scmp.com/news/china/science/article/3076775/chinas-new-solar-telescope-biggest-operation-now?fbclid=IwAR2Y0SPkvx4gyNCvIgY99agqU6448ulfSSbZW4uERRzzZdI_W3btI7ObWuQ

Scientists in southwest China on Tuesday said they had built the world’s second biggest solar telescope, which they say will provide more accurate data and improve forecasting.

With a 1.8-metre aperture, the Chinese Large Solar Telescope (CLST) was developed by the Institute of Optics and Electronics at the Chinese Academy of Sciences in Chengdu, Sichuan province.

The world’s first large, three-engine utility drone recently made its first flight. Developed by Chengdu-based Tengden Technology Co, the drone is a three-engine variant of Tengden’s twin-engine TB Twin-tailed Scorpion, as this design is a world first for drones. The drone has a width of 20 meters and a length of 11 meters. It is equipped with three piston engines, with one under each wing and one on its tail, enabling it to have a maximum takeoff weight of 3.2 tons and an endurance of 35 hours.The drone has a flight ceiling of 9,500 meters, a max climb rate of 10 meters a second and a top speed of more than 300 kilometers an hour.

China has finished building the world’s most powerful ion thruster and will soon use it to improve the mobility and lifespan of its space assets, according to a state media report this week.

Researchers at the 502 research institute, which operates under the China Aerospace Science and Technology Corp. in Beijing, have delivered a new-generation Hall-effect thruster unit to Chinese customers in the space industry, the report by the Science and Technology Daily stated.

The machine will outperform all of the ion thrusters used on satellites or spacecraft that are currently in use, it added. The daily is run by the Ministry of Science and Technology.

A self-elevating wind turbine installation vessel has been delivered Thursday to a subsidiary of China Communications Construction Company.

The vessel, developed by Shanghai Zhenhua Heavy Industries Co., Ltd., integrates multiple functions such as large equipment hoisting, installation and transportation.

It is 90 meters long and 40.8 meters wide. With a deck area of 2,400 square meters and a variable load of around 3,200 tonnes, the ship can accommodate three six-megawatt wind turbines or two eight-megawatt wind turbines.

Tsinghua Unigroup, one of China’s leading chipmakers, has hired Japanese semiconductor industry veteran Yukio Sakamoto as a senior vice president and also head of the company’s Japan unit.

Sakamoto, 72, served as chief executive of once-leading Japanese chipmaker Elpida Memory, which was established by combining the memory chip units of NEC and Hitachi.

Sakamoto led Elpida for over a decade, from 2002 to 2013, successfully listing the company’s shares on the first section of the Tokyo Stock Exchange in 2004. But the financial crisis and falling chip prices hurt the company’s finances, eventually leading to its bankruptcy in 2012 and its acquisition by U.S. peer Micron Technology the following year.

Besides Sakamoto’s experience, the Chinese government-backed Unigroup likely aims to put his connections in Japan and beyond to work as it expands its reach.

On 24 January, scientists at the Institute of Neuroscience (ION) in Shanghai reported that they had used gene-editing to disable a gene in macaque monkeys (Macaca fascicularis) that is crucial to their sleep–wake cycle. The scientists then cloned one of those monkeys to produce five primates with almost identical genes.

It is the first time that researchers have cloned a gene-edited monkey and proof of principle for the researchers’ plan to create populations of genetically identical primates that they say will revolutionize biomedical research. Some of the researchers are part of the new International Centre for Primate Brain Research, which has the goal of creating such populations and received government funding in November.

In Europe and the US, non-human-primate research increasingly faces regulatory hurdles, costs and bioethical opposition. This stands in contrast to China; the country’s 2011 five-year plan set primate disease models as a national goal. The science ministry followed up by investing 25 million yuan (US$3.9 million) into the endeavour in 2014.
