1. Rocket for mission to Mars on launchpad
China's first independent Mars exploration program has come one step closer to reality with the Long March 5 heavy-lift carrier rocket being moved to its launchpad at the Wenchang Space Launch Center in Hainan province on Friday morning.
The rocket, which will lift Tianwen 1 to Mars, was taken out of its testing complex at around 8 am and spent nearly two hours on tracks on its way to the launchpad.
It will blast off between late July and early August to transport Tianwen 1, also known as Quest for Heavenly Truth 1, to an Earth-Mars transfer trajectory. Tianwen 1 is designed to orbit the red planet and land a rover on the Martian surface for scientific operations.
2. China's 10-MW offshore wind turbine starts operation
An offshore wind turbine with a capacity of 10 MW started operating in East China's Fujian province on July 12. It is estimated that the wind energy converter, jointly developed by DEC and China Three Gorges Corporation, can produce 40 million kWh of clean energy every year at an average wind speed of 10 meters per second.
The annual power output can support the average electricity consumption of 20,000 households of three in a year. The turbine will reduce coal use by 13,000 tonnes and cut carbon dioxide emission by 35,000 tonnes.
According to DEC, the wind turbine has set a new record for China's unit capacity of offshore wind turbines and is expected to be put into mass production in the near future.
3. Smart gloves turn sign language gestures into speech
Bioengineers of the University of California, Los Angeles designed new smart gloves that can translate American sign language into an English voice by using a mobile phone application. The electronic sensor in the glove can intelligently recognize hand movements, collect information, and convert it into electronic signals, which are then sent to the circuit board on the wrist. The mobile phone can convert the signal, which is transmitted by the circuit board into spoken language at a rate of about one word per second.
4. Cancer cells can adapt to immune cells
Recently, researchers at Johns Hopkins University in the United States have used molecular expression profiling and computational analysis to check suspected molecular interaction between immune cells and cancer cells, as well as to identify interactions that may regulate cell communication. They then discovered a new mechanism for breast cancer cells to avoid the immune system transfer or spread to other parts of the body. This helps to develop targeted therapy, stop or prevent breast cancer metastasis, as well as reduce deaths.
