WASHINGTON, May 26 (Xinhua) — Scientists proposed a new theory about the origin of oceans on Earth. They suggested that comets played a key role in delivering the life-enabling water to our planet billions of years ago.

The study published in the latest journal Astronomy and Astrophysics Letters showed that water in many comets may share a common origin with Earths oceans.

The worlds largest airborne observatory SOFIA operated by the U.S. space agency NASA found that Comet Wirtanen, as it made its closest approach to Earth in December of 2018, contains ocean-like water.

SOFIA, the Stratospheric Observatory for Infrared Astronomy, is a Boeing 747 jetliner modified to carry a 2.7-meter diameter telescope, according to NASA.

Observing at high altitudes above much of the Earths atmospheric water allowed the telescope to accurately measure the ratio of regular to heavy water in Comet Wirtanen. The regular water is H2O, while the heavy water is called HDO, which has an extra neutrally-charged particle called a neutron inside one of the hydrogen atoms.

The data showed that Comet Wirtanens water ratio is the same as the Earths oceans, according to the study.

Comparing the new data with previous studies of comets, the scientists found the ratio of regular to heavy water was not linked to the origin of the comets, for example, whether they were from the Kuiper Belt or the outer fringe of the solar system.

Instead, the ratio was related to how much water was released from ice grains in the comets coma compared to directly from the snowy surface, implying that all comets could have a heavy-to-regular water ratio similar to Earths oceans.

If comets have the same ratio of these water types as Earths oceans, it indicates that the water in both may share a common origin, according to the researchers.

A remote-controlled car powered by 5G has wowed spectators as it successfully made a left turn, avoided barriers and backed into a parking lot, all controlled by a person 1,000 kilometers away.

The signal transmission delay stayed within one millisecond, said an employee with Datang Mobile Communications Equipment Co. Ltd, who presented the technology at the recently concluded Third World Intelligence Congress in Tianjin, northeastern China.

Another highlight at the conference was Muse, a concept autonomous vehicle manufactured by ICONIQ Motors, an emerging Chinese car brand. The car does not have a steering wheel. All the driver needs to do is to input the destination, and the car will drive there with the guidance of a highly accurate navigation system.

鈥淭he traditional automobile industry is in transition. Self-driving cars and intelligent connected vehicles are building a bright future for the industry,鈥?said Carsten Breitfeld, CEO of ICONIQ.

China has marched into a new chapter of self-driving technology, said Du Zhibin, director of China Automotive Technology and Research Center Co., Ltd. Automotive Data Center.

Self-driving technology is speeding up the transformation from theory to practice. John Hopcroft, an academician with the Chinese Academy of Sciences, believes that driving jobs may disappear completely with the development of autonomous driving technology.

Self-driving technology won鈥檛 stop with passenger vehicles. For example, a self-driving tractor recently completed road tests in Changsha, Hunan province. Equipped with an intelligent system, the tractor can work automatically, plowing fields without the need for human intervention.

With the approach of full commercial use of 5G, local governments in China have intensively introduced their plans on 5G development recently, as regions like the Pearl River Delta region, Yangtze River Delta region and Beijing-Tianjin-Hebei region are gearing up to cultivate industrial clusters valued at trillions of yuan, according to a report by Economic Information Daily.

At present, more than 20 provincial-level regions have completed 5G call tests and more than 500,000 commercial 5G base stations are expected to be built in South Chinas Guangdong, North Chinas Hebei, East Chinas Zhejiang and Jiangxi, and Central Chinas Hubei provinces and the cities of Shanghai, Harbin, Tianjin, Chongqing and Wuhan in the future, the report said.

With technologies and products related to the 5G network maturing, the main parts of the 5G industrial chain, including systems, chips and terminals, are ready for commercial use, Wen Ku, a spokesman for the Ministry of Industry and Information Technology, said on Tuesday.

The report said the ministry, having made a general plan for 5G application, is estimated to formally issue 5G licenses at some point this year.

As one of Chinas first batch of 5G pilot cities, Guangzhou will build 10,000 5G base stations by the end of year, aiming to take a lead to achieve the commercial use of 5G this year.

Shanghai plans to build 10,000 and 30,000 5G base stations by this year and by 2021 respectively, to realize deep coverage of 5G networks in the whole city and build itself into a leading pilot area of 5G network construction.

According to a 5G development plan released by Guangdong province on May 15, the Pearl River Delta region will be built into a 5G broadband city cluster that has world-level 5G industrial agglomeration area and 5G fusion application area.

In addition, the province proposed a 5G industrial agglomeration area valued at trillions of yuan that will be developed in the Guangdong-Hong Kong-Macao Greater Bay Area.

Earlier, Jiangsu province also released a notice, proposing the three provinces and one city in the Yangtze River Delta region, which referred to Jiangsu, Zhejiang and Anhui provinces and Shanghai, should jointly promote the region to become a national 5G construction and application demonstration area.

As early as 2016, authorities in Beijing, Tianjin and Hebei province signed a cooperation agreement on the coordinated development of informatization, mapping out plans on 5G network construction.

The coordinated layout of 5G development of major regions can benefit the construction of a connected regional network infrastructure, which will help them explore the services and derivative values of 5G application in a larger scope and to a greater extent, play leading roles for other regions in the country, Feng Xiaohui, a consultant at Chinese research firm CCID Consulting Co, said.

Telecom operators also are intensively issuing 5G deployment plans to accelerate 5G test and network construction.

The report said China Mobile has carried out 5G scale tests and application demonstrations in 17 cities, China Unicom is achieving consistent coverage of a 5G trial network in seven cities, including Beijing, Shanghai, Guangzhou, Shenzhen, Nanjing and Hangzhou, as well as Xiongan. It plans to achieve 5G network coverage in 33 cities selected areas, and China Telecom plans to accelerate 5G network deployment in some key cities, and build 20,000 base stations in 2019.

More than 2 million 5G base stations are expected to be invested and built nationwide by 2022, Zhang Yingqiang, a researcher with the China Center for International Economic Exchanges, said, according to the report.

In addition, the China Academy of Information and Communications Technology predicted the total investment on 5G networks will reach 90 billion yuan to 1.5 trillion yuan between 2020 and 2025, with telecom enterprises operation revenue related to 5G reaching 1.9 trillion yuan, the report said.

However, Feng warned that as 5G technologies and standards are not yet fully mature at present, for local governments, how to avoid excessive risks in choosing a roadmap and making early investment while promoting 5G development has become a focus issue.

GUIYANG, May 27 (Xinhua) — Authorities in southwest Chinas Guizhou Province have been using big data to guarantee food safety for student meals.

In Guizhous Tongren City, authorities use a cloud computing platform to supervise what students are eating, where the food is produced and who delivers it.

With analysis through big data, we arrange meals according to the students specific conditions, said Yang Ling, with a big data platform in Guizhou.

Through the platform, authorities in Guizhou can supervise food safety more precisely, Yang said.

In Tongren, the food for 457,600 students in 3,070 schools has been included in the system, while the information of 588 agricultural production bases is also listed.

The system also includes many poverty-stricken farmers in Guizhou, helping them out of poverty by purchasing food from them, authorities said. In the first quarter alone, transactions reached 495 million yuan (72 million U.S. dollars).
