BEIJING, May 2 (Xinhua) -- The following are the highlights of China's science news from the past week:
FAST RADIO BURST
Astronomers have recently discovered a new fast radio burst (FRB), mysterious signals believed to be from the distant universe, with the largest and most sensitive radio telescope ever built.
An international team led by scientists at the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) made the discovery by analyzing the data from the Five-hundred-meter Aperture Spherical Radio Telescope (FAST).
China's lunar rover Yutu-2, or Jade Rabbit-2, has driven 447.68 meters on the far side of the moon to conduct scientific exploration of the virgin territory.
Both the lander and the rover of the Chang'e-4 probe have ended their work for the 17th lunar day, and switched to dormant mode for the lunar night due to the lack of solar power, according to the Lunar Exploration and Space Program Center of the China National Space Administration.
SOIL MOISTURE IN KARST AREAS
Chinese researchers have disclosed that precipitation was more important than temperature for soil moisture changes in the karst areas in China.
Soil moisture is a crucial factor in karst ecological restoration and construction. Researchers from the Institute of Geochemistry of the Chinese Academy of Sciences hoped to understand its spatiotemporal evolution characteristics in the country's karst areas.
REMOTE SENSING FOR WATER CLARITY
Chinese researchers have mapped the country's water clarity of lakes and reservoirs in 30-meter resolution using remote sensing imagery data.
Water clarity is a reliable indicator for quantifying eutrophic status, said their recently published research article in journal Remote Sensing of Environment. The researchers from the Northeast Institute of Geography and Agroecology of the Chinese Academy of Sciences collected 2,152 samples from 34 field campaigns from 2013 to 2018.
BLOOD PRESSURE MONITORING
Chinese scientists have developed a skin-like integrated optoelectronic system that can be used as a wearable device for blood pressure monitoring.
Developed by researchers from Tsinghua University, the system looks like a thin and soft Band-Aid, which can be attached to human skin to achieve dynamic monitoring of blood pressure and blood oxygen and can wirelessly transmit the data to smart terminals in real-time.
TELESCOPE FOR MARS MISSION
China is constructing the largest steerable radio telescope in Asia with a 70-meter-diameter antenna to receive data from its first Mars exploration mission which is expected to be launched this year.
The telescope, with an antenna the size of nine basketball courts, was built by the National Astronomical Observatories of the Chinese Academy of Sciences in Wuqing District of northern China's Tianjin. Enditem
