State Grid Jining Power Supply Company applies multiple means such as unmanned aerial vehicle autonomous inspection, remote camera monitoring, infrared temperature measurement, etc., to carry out inspections of power facilities, do a good job in the operation and maintenance of electric vehicle charging piles, and ensure reliable power supply in scenic spots and comfortable power consumption for tourists.

China's first sea-spanning high-speed railway capable of a top speed of 350 kilometers per hour is expected to start service in East China's Fujian Province on Thursday. The line shortens the travel time between Fuzhou and Xiamen to at most 55 minutes in a bid to enhance the connectivity between the two major cities in the province, the Xinhua News Agency reported on Wednesday. 

With a total length of 277 kilometers, the railway starts from Fuzhou, passes through Putian, Quanzhou and Xiamen and ends in Zhangzhou.    

The high-speed railway is yet another intelligent railway route to enter commercial service following the Beijing-Zhangjiakou high-speed railway and Beijing-Xiong'an high-speed railway, demonstrating new progress in the intelligentization of China's high-speed railway technology. 

The railway was designed using the latest modeling technology based on digital information, which realized the integrated management of high-speed railway's design, construction and operation. 

The BeiDou Navigation Satellite System, intelligent robots and environmentally friendly materials were adopted to facilitate the construction of cross-sea bridges. An intelligent command and dispatch system is used to ensure trains stay on schedule and operate efficiently. A big data analysts system can monitor and report all potential weather disasters, ensuring the safe operation of each train on the route. 

The opening of the railway connects multiple cities along Southeast China's coast and forms a belt full of tourism sites. It will also form a high-quality traffic channel connecting Ningbo in East China's Zhejiang Province and Guangzhou in South China's Guangdong Province with other high-speed railway routes that have already been completed or are still under construction. 

Wang Jianmin, a senior cross-Straits expert at Minnan Normal University in Fujian Province, told the Global Times that the opening of the Fuzhou-Xiamen high-speed railway shows China has the technological ability to build a cross-Straits railway. 

"What's more, it also offers expectations for people on the both sides of the Straits that the railway will be the foundation of a cross-Straits railway in the future," said Wang.

The China International Import Expo (CIIE) is a "perfect platform" for exchanging ideas within the global fashion and textile industry, a senior representative of the Spanish fashion giant Inditex told Xinhua in an interview on Thursday.

It will be the fourth time that Inditex, which owns popular brands such as Zara, Bershka, Massimo Dutti and Stradivarius, will take part in the trade fair. CIIE is aimed at economic globalization, and opening the Chinese market to the world.

"The CIIE is a perfect platform for us to keep learning and exchanging ideas with the most inspiring and also relevant industry players, stakeholders and partners," Amy Yu, Inditex's Greater China Head of Communication, told Xinhua.

"This is an international platform that welcomes both domestic and international stakeholders, so it's definitely an opportunity for us to connect both at home and abroad," Yu added.

This year will be the sixth time that the CIIE, which is hosted by China's Ministry of Commerce and the Shanghai Municipal People's Government, will be held in Shanghai's National Exhibition and Convention Center. The trade fair runs from Nov. 5 to 10.

Some 150,000 business professionals from over 100 countries and regions around the world are expected to participate, say the expo's organizers. Events at the fair include networking meetings, seminars and workshops, and new product releases.

Zara opened its first store in China's Hong Kong in 2004, followed by another in Shanghai in 2006, where Inditex's Asia regional HQ is also based. The company now operates 50 stores around China for four of its brands (Zara, Zara Home, Massimo Dutti and Oysho).

"China is not only a retail market where we operate stores and different brands, but also a talent center, and a place where we continuously get inspired," said Yu. "Our business activities started in China as early as the nineties, when we started cooperation with the local textile suppliers."

The Spanish company's involvement in China extends beyond business concerns to social engagement, Yu underlined.

The company worked with the China Youth Development Foundation and 33 schools for the benefit of more than 5,000 students in China, and with the China Environmental Protection Foundation for clothes donation and recycling projects, she said.

The number of China-Europe Chang'an freight train, connecting Xi'an in Northwest China's Shaanxi Province, with Moscow, Russia, has exceeded 20,000 trips since entering service on November 11, 2013, Xi'an International Trade & Logistics Park, the operator of the train service told the Global Times on Saturday. 

The 20,000th Chang'an freight train carrying 165 vehicles departed from Xi'an on September 28, which was also the 3,947th freight train departing from the city in 2023. As of September 28 this year, the number of departures by Chang'an train saw a 29.7 percent increase year-on-year. The freight volume hit 3.5 million tons, up by 34.7 percent year-on-year. 

2023 marked the 10th anniversary of the Chang'an freight train's launch as well as the China-proposed Belt and Road Initiative (BRI). In the past decade, the number of the transport routes has grown from one to 17, as the China-Europe freight train service covers the entire Eurasia continent. 

In addition, the category of the Chang'an train service has increased from merely drilling equipment in the beginning to now include textile products, machinery equipment, electronic products, rubber products, auto vehicles and other products. Grain, wood and minerals from the countries joining the Belt and Road Initiative are among the goods being imported to China. 

The maximum capacity of the Xi'an International Trade & Logistics Park can reach 5.4 million standard containers and 66 million tons of freight per year, and can facilitate 15 trains each day. A representative from the park pledged to further improve cargo transport facilities, attract investment and build domestic currencies settlement system, in order to facilitate the development of the BRI.

On Sunday afternoon, China successfully launched the Macao Sicence-1 space satellite for scientific use , the first of its kind. The  satellite was jointly developed by mainland and Macao agencies, Global Times learned from China National Space Administration (CNSA.)

The satellite was successfully launched into preset orbit via a Long March-2C carrier rocket from the Jiuquan Satellite Launch Center in Northwest China at 4 pm on Sunday. 
This was the 474th flight mission of the Long March carrier rocket series. A scientific experiment satellite named Luojia-2 was sent into space at the same time.

As the world's first low-latitude geomagnetic field and space environment scientific detection satellite, the Macao Sience-1, featuring the highest geomagnetic field detection accuracy  in China, will significantly improve the level of the country's space magnetic measurement technology, the CNSA said in a statement to the Global Times on Sunday. 

The project was jointly initiated by the CNSA and the government of China's Special Administrative Region (SAR) of Macao and the detection data will be shared by both sides, the CNSA noted. 

Such project explored a new path for cooperation between mainland and the Macao SAR, adding new impetus to the regional development of the Guangdong-Hong Kong-Macao Greater Bay Area and the high-quality development of aerospace technology, the CNSA said. 

After the satellite is launched into orbit, it will be able to function as a good complementary observation point together with the European Swarm satellite and the Zhangheng-1 satellite, realize the measurement and research of the Earth's low-latitude magnetic field and space environment changes and monitor the temporal and spatial changes of the magnetic field in the South Atlantic geomagnetic anomaly area. 

Additionally, the satellite will provide valuable observational data for human beings to study the evolution of the geomagnetic field for a long time, to further promote China's research progress in the fields of lithospheric magnetic field, origin of geomagnetic field, space weather forecast, geomagnetic navigation, spacecraft space operation safety and  high-precision satellites. 

Monday marks the 11th International Memorial Day for the "Comfort Women," which refers to victims forced into sexual slavery by Japanese troops during World War II. More than 200,000 Chinese women were tortured between 1931 and 1945 with fewer than 20 survivors still alive today in the Chinese mainland. 

The "comfort women" system was an organized and planned action directly orchestrated by the then Japanese militarist government during World War II and was executed by the Japanese troops. 

The victims of the "comfort women" system were not limited by race or borders. About 400,000 Asian women from China, the Korean Peninsula, Southeast Asia and the European and American countries were forcibly conscripted as "comfort women." 

In a video released by the Memorial Hall of the Victims in Nanjing Massacre by Japanese Invaders on its Sina Weibo, a Chinese "comfort women" survivor recalled her experience and fear of being imprisoned by the Japanese invaders. 

Many netizens left messages online to call on the public not to forget the suffering of "comfort women." 

One netizen said that history will not fade with the passage of time, and facts will not disappear due to eloquent denials, noting that revisiting history is not about indulging in suffering and hatred, but about ensuring that peace endures and justice prevails. Another netizen said that war is like a mirror that allows people to better understand the preciousness of peace. 

In South Korea, there left only nine surviving "comfort women" after one survivor passed away in May this year. All the South Korean survivors are now in their 90s. 

On August 14, 2022, which was designated the International Memorial Day for "Comfort Women" in 2012 by the 11th Asian Alliance Conference for "Comfort Women," South Korean people held a protest rally in Seoul with portraits of "comfort women" and their testimonies. 

 Beijing municipal health authorities have started soliciting public opinions  on a set of trial measures aimed at regulating online diagnosis and treatment. The trial measures require medical institutions to strengthen drug management and prohibit the use of artificial intelligence (AI) to generate prescriptions automatically, the Beijing Daily reported on Monday. It is a move to further improve and regulate online medical services in the face of growing demand.

The public can give feedback to the Beijing municipal health commission before September 16.

Based on the trial measures, medical institutions shall conduct real-name certification of medical personnel who carry out online medical services. Doctors who conduct internet medical services should obtain the corresponding qualification, as well as possess more than three years of independent clinical work experience and the consent of their registered medical institutions.

Other personnel or AI software shall not be falsely used or replace a doctor in providing diagnosis and treatment services, according to the trial regulations.

In a bid to promote the sound development of the AI sector and safeguard national security and public interest, China's internet watchdog and several other authorities issued temporary rules for managing generative AI services in July. 

Additionally, online diagnosis and treatment must be implemented under a real-name mechanism. This requires patients to provide their real identity and basic information. They should also provide medical records with a clear diagnosis, such as outpatient medical records before receiving online medical services.

The Beijing municipal health commission will establish a platform to supervise medical institutions that carry out internet diagnosis and treatment. Medical institutions should upload and update relevant practice information in a timely manner and undergo supervision.

More and more people have become interested in remote medical services due to the convenience they provide. Local authorities are also promoting internet-based digital medical services to provide better services to the public. For instance, in Qingdao, East China's Shandong Province, a citywide health platform has connected with 10 districts and 3,498 medical institutions, according to Qingdao health authorities on Saturday. 

However, more regulations are needed in the rapidly developing online medical services industry as some platforms lack pricing standards or internet diagnosis and treatment qualifications, according to media reports.

According to the Digital China Development Report 2022 released in May, by October 2022, more than 2,700 internet hospitals had been set up across the country, providing online medical services to more than 25.9 million people.

In March 2022, the country's health authorities released a trial guideline on internet-based diagnosis and treatment. Similar to the Beijing measures, doctors are required to conduct real-name certification before providing medical services. Other personnel or AI software shall not be falsely used or replace a doctor in providing diagnosis and treatment services, the regulation said.

Taiwan billionaire and Foxconn founder Terry Gou Tai-ming announced on Monday that he will run in the 2024 elections for Taiwan's regional leader, making next year's vote a complicated four-way race. Analysts said that this is likely to further divide the island's opposition camp in favor of secessionist ruling party candidate Lai Ching-te. 

According to the latest polls conducted in mid August by Taiwan media outlets and institutions, without Gou's participation, ruling Democratic Progressive Party (DPP) candidate Lai, who is currently the deputy leader of the island, is now the front-runner with 37 to 42 percent, while Taiwan People's Party candidate Ko Wen-je ranks second with 25 to 28 percent, and Hou Yu-ih of the major opposition party Chinese Kuomintang (KMT) getting 20-22 percent. 

According to Taiwan polls that include Gou,  with Gou's participation, Lai's front-runner position is virtually unaffected while the opposition candidates are impacted significantly, as Ko gets only about 16-17 percent, KMT's Hou gets 15-16 percent, and Gou has only 12 percent. 

Analysts said this doesn't mean the DPP is popular, as most polls show that Taiwan residents who want to end the DPP rule are in the majority, as the combined support of opposition candidates is more than Lai's, but the problem is that the opposition camp is becoming divided due to the power struggle between the two opposition parties, and now the independent candidate Gou is dividing the field further. 

The three opposition candidates are yet to reach a consensus on forming an alliance to run in the elections. Even if they do reach agreement on running together, which is very unlikely as they all refuse to give in and serve as deputy candidate, Lai is very likely to win, and unfortunately, the will of the majority on the island to end the DPP rule might not be realized, Li Fei, a professor at the Taiwan Research Center at Xiamen University, told the Global Times on Monday.

"If Lai gets elected, cross-Taiwan Straits relations will be in danger, so the mainland is preparing for any possible scenario, including the worst one," Li noted. "But there are still a few months to go, and it would still be too early to say who can win eventually." 

In an apparent response to Gou's announcement to run, the KMT said in a post on its Facebook account Monday, after his announcement without mentioning him, that "if we share similar values, then we can work together," but vowed that mainstream public opinion will not accept any act that "hurts comrades and favors adversaries." 

Gou has been labeled by Taiwan media as a pro-mainland figure who has deep business relations in the mainland, and in order to preserve and resume cross-Straits cooperation that significantly benefit Taiwan, he also supports peace and opposes secessionism. However, experts said that his decision driven by political ambition is in fact helping the DPP authorities.

However, many Chinese mainland netizens and pro-reunification Taiwan residents have an interesting theory: If the DPP's Lai wins next year, this could speed up the reunification process, as the mainland will find it easy to completely abandon "the illusion of peaceful reunification" and make tough decisions to solve the Taiwan question immediately. Therefore, these people welcome Gou's act to run for the election, as they believe this will consolidate Lai's advantage.

Zheng Bo-yu, manager of the Vstartup Station of Taiwan, a company serving Taiwan youth seeking to study, work and launch startups on the mainland, said, "Many friends of mine in Taiwan who support cross-Straits cooperation and exchanges made a joke about the current election: Why don't we just vote for Lai and let the DPP win, so that the mainland will have an easier time making the decision to solve the Taiwan question once and for all, so that we don't need to be worried about the uncertain cross-Straits tension and US intervention anymore."

Li said the Chinese mainland has enough measures available to deter and counter secessionists and foreign interference forces, but the mainland is still making great efforts and showing great patience to seek peaceful reunification. 

"But it's possible that, if Lai eventually wins, deeper and more reckless collusion between the DPP and the US will wipe out the possibility of peaceful reunification, and the mainland will be forced to take action," Li warned.

Hobbits disappeared from their island home nearly 40,000 years earlier than previously thought, new evidence suggests.

This revised timeline doesn’t erase uncertainty about the evolutionary origins of these controversial Indonesian hominids. Nor will the new evidence resolve a dispute about whether hobbits represent a new species, Homo floresiensis, or were small-bodied Homo sapiens.

Hobbits vanished about 50,000 years ago at Liang Bua Cave on Flores, an island situated between Borneo and Australia’s northern coast, say archaeologist Thomas Sutikna of the University of Wollongong, Australia, and his colleagues.
Cave sediment dating to about 12,000 years ago, which lies just above soil that yielded H. floresiensis remains, provided an initial estimate of when these diminutive hominids died out. But that sediment washed into the cave long after H. floresiensis was gone, covering much older, hobbit-bearing soil, the researchers report online March 30 in Nature.

Using the initial age estimate, researchers had previously concluded that hobbits survived for tens of thousands of years after Homo sapiens passed through Indonesia and reached Australia around 50,000 years ago. It now appears that hobbits instead hit an evolutionary dead end around that time, Sutikna’s group says.

The centerpiece of hobbit finds, a partial skeleton, comes from an individual who lived well before then, the scientists add. Measurements of the decay of radioactive elements in an arm bone from the partial skeleton indicate that the find dates to between 86,900 and 71,500 years ago. Until now, researchers suspected these bones were only about 18,000 years old.
Based on the new dates, “there was possibly no overlap or interactions between H. floresiensis and H. sapiens on Flores,” says paleoanthropologist Richard Potts of the Smithsonian Institution in Washington, D.C.
Hobbits disappeared before the earliest skeletal evidence of humans on Flores, says paleoanthropologist and study coauthor Matthew Tocheri of Lakehead University in Thunder Bay, Canada. H. sapiens bones date to around 11,000 years ago on the Indonesian island. That undermines a controversial argument that a partial hobbit skeleton comes from a human with a developmental disorder (SN: 11/18/06, p. 330), Tocheri says.

Paleoanthropologist Russell Ciochon of the University of Iowa in Iowa City agrees. H. floresiensis probably descended from a large-bodied Asian Homo erectus group that reached Flores roughly 1 million years ago, he says. On islands, large-bodied mammals tend to become smaller, presumably in response to limited food sources and other factors.

But in a joint e-mail to Science News, two researchers who regard hobbits as humans — and the partial hobbit skeleton as displaying signs of Down syndrome — stick to their guns. Regardless of the new dates from Liang Bua Cave, hobbit bones fall within the range of skeletal sizes and shapes observed in people today, assert Robert Eckhardt of Penn State and Maciej Henneberg of the University of Adelaide in Australia. H. sapiens could have reached Flores and nearby islands (SN: 2/6/16, p. 7) when Sutikna’s group says hobbits were alive, they claim.

It’s not known whether humans or other Asian hominids, such as Denisovans (SN Online: 3/17/16), reached Flores more than 50,000 years ago at a time of lowered sea levels and possible drought on the island, Potts says. If they did, intruding species might have pushed an already reeling hobbit population to extinction.

Liang Bua Cave excavations also suggest that other Flores animals, including vultures, giant marabou storks and an extinct elephant relative, vanished around the same time that the hobbits did.

Annual excavations from 2007 through 2014 clarified how sediment accumulated in the cave. A thick soil deposit containing hobbit remains had substantially eroded before being covered by soil layers that washed into the cave starting around 20,000 years ago. Techniques for dating soil, rock, volcanic ash and bone indicated that hobbits’ skeletal remains ranged in age from 100,000 to 60,000 years ago. Stone tools probably made by hobbits dated to between around 190,000 and 50,000 years ago.

Liang Bua Cave preserves a late slice of H. floresiensis life on an island probably reached by toolmaking hobbit ancestors around 1 million years ago (SN: 6/3/06, p. 341), Tocheri says.

Researchers don’t know what happened during the roughly 800,000 years between hobbit ancestors’ arrival on Flores and hobbits’ last evolutionary stages. “If there was a book that chronicled the evolutionary history of H. floresiensis, we would have only a few tattered and torn pages with the rest missing,” Tocheri says.
