BEIJING, May 29 (Xinhua) -- The following is a summary of published science and technology news of China.

OCEAN HEAT

Chinese researchers have said that the layer of water between depths of 200 and 1,000 meters in the South China Sea stored more heat during the last glacial period, a finding that could throw more light on the warming of the atmosphere.

Ocean heat plays an important role in influencing Earth's climate. Researchers from the South China Sea Institute of Oceanology under the Chinese Academy of Sciences hoped to investigate the changes in ocean heat content over a millennial scale, as well as the mechanisms that control the transmission of heat in the ocean's interior.

"EXTINCT" FLOWER SPECIES

A flower not seen for decades in the wild and thought to be extinct has been found by scientists in a mountainous region of southwest China.

An expedition led by the Kunming Institute of Botany, under the Chinese Academy of Sciences, found a strain of Rhododendron adenosum, also known as the Flora of China, in Liangshan Yi Autonomous Prefecture in Sichuan.

5G NETWORK

With the last outdoor base station installed, Shenzhen Bao'an International Airport has embraced the full coverage of the 5G network, three months ahead of schedule, the airport said.

Since this year, the airport has accelerated the construction of a 5G network by building 41 outdoor base stations, with signals that can cover all places including terminals, the flight area and the freight transport area.

The speed of the 5G network is more than 15 times faster than the current 4G network and will support superfast movie downloads, according to initial tests. Enditem
