BEIJING - China's Five-hundred-meter Aperture Spherical Radio Telescope (FAST), the world's largest single-dish radio telescope, will have with a new receiver installed to boost its efficiency in surveying the sky.The 19-beam L-band receiver, first of its kind worldwide, is expected to be put into use in early June and it will increase FAST's survey speed by five to six times, according to Friday's Science and Technology Daily.The receiver was jointly developed by scientists from China and Australia. It weighs 1.2 tons and cost over 20 million yuan (about $3.14 million).Jin Chengjin, chief engineer of FAST's receiver system, said the new receiver has the highest sensitivity and will greatly improve FAST's efficiency in searching for new pulsars and spectral lines.Located in a natural, deep round karst depression in Guizhou province, Southwest China, FAST is believed to be the world's most sensitive radio telescope.Its tasks include observation of pulsars, exploration of interstellar molecules, and monitoring interstellar communication signals. rubber bracelets canada

[Photo by Zhang Wenkui/For China Daily] Beijing tops Chinese cities in approvals of innovative medical equipment, said the Medical Products Administration of the municipal government on Thursday. The State Council in October 2017 issued guidelines encouraging innovation in drugs and medical equipment by intensifying reform in the medical sector. The National Medical Products Administration has since approved 54 projects, one third of which were researched and developed by enterprises in the capital city. Innovations like neurosurgery navigation and positioning systems, along with implantable, phrenic nerve-stimulator kits have not only filled gaps in their respective fields, but also cater to public demand, the municipal administration said. One of the major reasons for the number of innovations is reduced review time, according to the administration. It now takes no longer than two days for review, down from the previous 20 days, and six days for registration and inspection, down from the previous 30. A degradable blood vessel stent, for example, recently hit the market as the first bioresorbable stent approved in China. Researched and developed independently in Beijing, the equipment is considered a significant breakthrough in coronary disease treatment.
