China recently verified a new morphing wing structure that can help build future cross-domain aircraft, with an expert saying on Tuesday that the cutting-edge technology is expected to undergo flight tests before being applied. 

The Aircraft Strength Research Institute of China, a subsidiary of the state-owned Aviation Industry Corporation of China (AVIC), successfully completed the theory verification on a full lattice distributed morphing wing structure based on mechanical metamaterials last week, AVIC said in an announcement posted on Sina Weibo on Monday.

During the verification, the morphing wing structure achieved distributed active torsional morph control, made breakthroughs in multiple core technologies including performance characterization of the mechanical metamaterials, cellular configuration design, reversible assembly of lattice structures, multi-point morph sensing and collaborative control, according to the announcement.

A video clip attached to the announcement shows a scaling model of a half-hollow lattice distributed wing structure changing its shape dynamically.

Wang Ya'nan, chief editor of Beijing-based Aerospace Knowledge magazine, told the Global Times on Tuesday that morphing wing is cutting-edge technology that enables aircraft to flexibly change form without using rigid rudder structures currently used on aircraft, which can only make limited moves in controlling the aircraft.

Morphing wing is like wings of birds that can make changes without many restrictions, enabling fine tunings, so it can provide better control over the aircraft, Wang said.

The technology can provide support to the design of future cross-domain variable geometry aircraft, AVIC said in the announcement.

A cross-domain aircraft is a type of aircraft designed to fly at very different altitudes, from low altitudes with dense atmosphere to high altitudes with thin air, as well as at very different velocities, from subsonic speeds to hypersonic speeds, Wang said. "This requires the aerodynamic shape of the aircraft to adjust based on the changes of the environment."

To achieve this goal, variable-sweep wing was developed, but it is still a rigid structure with limitations, Wang said, noting that the morphing wing can make flexible changes that can adapt to more flight environments, as long as the requirements of materials and structures are met.

Wang said he does not expect the new technology to be put into application any time soon, as he expects the morphing wing structure to undergo flight tests on demonstrators first, before being put on genuine aircraft for verification.

As the clock ticked into 2024, several Chinese provinces including East China's Anhui and Central China's Hunan began a new round of construction of major projects, signaling a robust start to the new year. The growth in investment brought an encouraging sign for economic growth.

Analysts told the Global Times on Thursday that this development laid a solid foundation for investment in 2024, and these new projects are expected to generate significant economic benefits and jobs, and ramp up investment that will drive economic growth.

On Tuesday, Anhui held a groundbreaking ceremony for the Hefei-Wuhan High-Speed Railway, along with the first batch of major projects for 2024. So far, 460 major projects have been launched in the province, with a total investment of 489.63 billion yuan ($68.5 billion).

These projects range from infrastructure to emerging industries and include 33 projects with an investment of more than 3 billion yuan.

Insufficient investment in 2023 hindered economic development in China, but the situation improved at the end of the year. With improving development expectations and new policies conducive to industrial development, investment is expected to further increase this year, Tian Yun, a veteran economist based in Beijing, told the Global Times on Thursday.

"I am most optimistic about the energy sector this year," Tian said. "As an emerging industry, it has shown promising growth momentum and proven to have the potential to inject vitality into China's economic growth."

Hunan Province started on Wednesday work on 11 major projects with a combined investment of 87.2 billion yuan.

Emerging industries are playing a pivotal role in driving investments. Among the 460 projects initiated in Anhui, 253 are in emerging industries, including new-energy vehicles, smart grids, advanced photovoltaic systems and new materials, with total investment of 247.66 billion yuan. 

All across China, regions are gearing up for a strong start to the new year, with a focus on emerging industries.

In Xiamen, East China's Fujian Province, 25 of the 63 newly launched projects are related to industries such as new energy, new materials and biomedicine, making up 39.68 percent of the total.

Central China's Henan Province on Monday announced policies to promote a robust economic start to the first quarter, with 100 projects each worth of 10 billion yuan in investment.

"I expect a rise in investment can provide the impetus to achieve 5 percent GDP growth for China in 2024," said Tian. 

As a cold wave swept across northern China, the Chinese capital welcomed its first snow of the winter on Sunday evening. Traffic in Beijing has also been affected by the snowfall, with heavy congestion during the morning rush hour on Monday.

Following the snowfall, Beijing was covered in a silver-white coat, presenting picturesque scenes at Beihai Park, the watchtowers and the Shenwu Gate of the Forbidden City. The snow covered the buildings of the Forbidden City, making the red walls and golden tiles appear more vibrant, creating a striking contrast with the pristine white snow, resulting in a beautiful and magnificent sight. Coincidentally, the Forbidden City is closed on Mondays, presenting a serene and peaceful atmosphere after the closure.

Different from the Forbidden City, the Universal Studios theme park is bustling as usual.  Many visitors wearing wizard robes headed straight to the Harry Potter's Wizarding World area, checking in at the silver-clad Hogsmeade Village, as if they have "traveled" into the classic snow scenes from the movies.

Netizens were amazed by the snowy scenes and expressed optimism for a prosperous year with auspicious snowfall. Many netizens from the southern regions expressed their envy, saying, "Beijing has already seen the first snow, while in Shenzhen, Guangdong Province, we still need to use electric fans. Southerners who have never seen snow are eager to personally experience it!"

Also enjoying the first snow was the star giant panda Meng Lan, "the 3rd Prince of Xizhimen," who once went viral for "breaking through" the enclosure at the Beijing Zoo. On the snowy day, Meng Lan rolled and happily frolicked in powedery snow. Visitors couldn't help but chuckle at the adorable sight.

From 7 pm on Sunday to 6 am on Monday, the average snowfall in Beijing was 5.1 millimeters, with the urban area averaging 5.8 millimeters. The highest snowfall occurred in Pupuwa, Fangshan district reaching 9.8 millimeters. According to Beijing Public Transport Group, as of 6 am, a total of 172 bus routes had been adjusted due to the snowy weather, including 157 routes that had been suspended, nine routes with adjusted sections, and six routes with detours and skipped stops.

The Beijing Capital International Airport plans to operate 1,100 flights and transport approximately 150,000 passengers on Monday. As of 7 am, 84 flights had been executed and 59 flights had been canceled. At 6 am, the airport initiated targeted de-icing operations, and a total of 22 flights had been de-iced. The overall operation of Beijing Capital International Airport remains normal.

Affected by a strong cold air mass, the meteorological department in East China's Shandong Province issued a blue warning for cold wave and a yellow warning for road icing on Saturday, and continued to issue a yellow warning for strong winds at sea on Sunday. Under the influence of the cold wave, there was also moderate to heavy snow and local blizzards in the northwest and central regions of Shandong. In addition, the city of Yulin in Northwest China's Shaanxi Province experienced significant rain and snow and a drop in temperatures on Sunday. Several local meteorological monitoring stations recorded snowfall at the level of heavy snow, and the average temperature dropped by 6 C to 8 C.

In Zhengzhou and Xinxiang, Central China's Henan Province, primary and secondary schools, as well as kindergartens, had half-day off on Monday.

On Sunday, a significant drop in temperatures occurred across most parts of Northeast China's Heilongjiang Province, with the lowest temperatures expected to reach -25 C to -30 C in some areas from December 10 to December 15. To cope with the cold weather, various measures had been taken to strengthen water and heating supply and other livelihood guarantees. In Fujin city, the local heating company has increased the frequency of inspections on heating equipment such as pipelines and valves to ensure the quality of heating.

To ensure the safety of passengers, the railway departments had suspended 112 passenger trains heading to Beijing, Xiamen, Chengdu, Taiyuan, among other routes, with some trains experiencing delays.

Researchers from the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences have proposed a new "nano-micro composite" delivery concept for vaccines and developed a single-dose, dry-powder, inhalable vaccine platform. The vaccine made in the laboratory based on the technology is effective in blocking respiratory viral infection and transmission in animal test, showing great promise for combating future emerging and epidemic infectious diseases. This study was published in Nature on Wednesday. 

In recent years, researchers have made significant progress in developing vaccines for infectious respiratory diseases. However, most of these vaccines are administered through intramuscular injection, which primarily induces a humoral immune response and relies on blood antibodies to neutralize the virus. This approach fails to trigger a mucosal immune response and establish a robust immune barrier in the respiratory tract, according to a release from the research group.

The current liquid form of vaccines requires to be stored in strict low-temperature, and the two- or three-dose vaccination schedule also impacts the overall vaccination rate.

In confronting these problems, professor Wei Wei and professor Ma Guanghui from the State Key Laboratory of Biochemical Engineering at IPE, in cross-disciplinary collaboration with professor Wang Hengliang and professor Zhu Li from the State Key Laboratory of Pathogen and Biosecurity, have developed a new vaccine platform.

This platform combines biodegradable microspheres with protein nanoparticles. The surface of these nanoparticles can simultaneously display multiple antigens, thus inducing a broad-spectrum immune response and expanding the range of vaccine protection. The platform also allows for the quick and convenient development of other respiratory virus vaccines due to the flexibility of antigen presentation.

The platform's unique nano-micro composite structure enables an efficient immune response in the lungs by facilitating high-performance delivery. Once antigen-nanoparticles are released, they can be efficiently taken up by antigen-presenting cells. 

Moreover, this dry powder vaccine significantly reduces storage and transportation costs, making it suitable for areas with limited refrigeration facilities, thus improving immunization rates.

The sustained release of antigens in the vaccine induces long-lasting humoral, cellular, and mucosal immunity with just a single inhalation

In cooperation with professor He Zhanlong of the Institute of Medical Biology of the Chinese Academy of Medical Sciences, the researchers developed a model of airborne protection, close contact protection, and airborne transmission blocking, which demonstrated that an inhaled vaccine is highly effective in preventing the virus infection and transmission.

"The components of this nano-micro system used natural proteins and approved polymer materials, and the effectiveness and safety of the vaccine have been systematically studied in non-human primates, indicating its great potential for clinical translation," professor Wei said.

President Xi Jinping on Monday met with Chief Executive of the Hong Kong Special Administrative Region (HKSAR) John Lee, who is on a duty visit to Beijing.

During the meeting, Xi heard a report from Lee on Hong Kong's current situation and the HKSAR government's work.

"The audience here in Chengdu is incredibly enthusiastic, and I deeply enjoyed the game. Every time we scored or made a good defensive play, the audience gave us big rounds of applause and cheers," basketball player Yu Ai-Che from the Chinese Taipei team told the Global Times on Monday evening after the competition against the Chinese team at the 31st FISU World University Games in Chengdu.

In Monday's Men's basketball competition, the Chinese Taipei team defeated the mainland team with a score of 97:84. Both teams had previously suffered two consecutive defeats by Lithuania and Brazil in the earlier group stage, which meant they had no chance of advancing to the top eight.

"The atmosphere in Chengdu is fantastic, and I'm extremely grateful to the audience. They continually cheered and clapped for our team throughout the game. I've played in the mainland when I was in high school, and I definitely want to play with mainland players again to improve both our techniques," said Yu Ai-Che after the competition.

In addition to the audience's passionate support for both teams from the first period to the last, the Global Times also noted that during the halftime break of the match, the panda-shaped mascot Rongbao and the entire audience sang the song "A Family Who Loves Each Other" together. The Taiwan island's folk song "Maiden of Alisan" resonated with the people present. The two teams also exchanged gifts before the start of the match.

Mainland player Zhang Ning said that he gave plush toys of Rongbao to his friends from the island of Taiwan, just as he would bring back souvenirs for his family.

The Chinese delegation made an impressive start on the first day of the 19th Asian Games in Hangzhou, East China's Zhejiang Province, on Sunday, clinching an astounding 20 gold medals across various sports, including rowing, shooting, wushu and swimming. 

In the rowing events, local Hangzhou girl Zou Jiaqi took the first gold medal of the Hangzhou Asian Games to start a Chinese gold rush at the Fuyang Water Sports Centre. Zou and her doubles partner Qiu Xiuping rowed a strong race in the lightweight women's double sculls final to finish nearly 10 seconds ahead of Uzbekistan, to the delight of the watching crowds both in the grandstands and on the banks of the course.

Qiu said that she was extremely excited when she saw the national flag and heard the national anthem as they rowed past the finish line. 

Zou told media that she wanted to tell her parents she was happy to see they were at the event. 

Speaking of their next goal, the Paris 2024 Olympic Games, the pair did not hide that they are reaching for the top podium. 

"Since we walked off the Hangzhou podium, Paris has become our goal," Qiu said. "We will restart from zero, completing every training session wholeheartedly. We hope to go to the top in Paris."

Later in the morning, Zhang Liang equaled the record of Li Jianxin by winning his fourth Asian Games gold medal in rowing. China won a further four of the five finals on the penultimate day of the rowing regatta. The men's pair was won by Lam San-tung and Wong Wai-chun, also marking China's Team Hong Kong's first gold medal of the ongoing Hangzhou Games.

China's six gold medals take their all-time Asian Games rowing total to 104, including 98 golds. The spectators at the event said that the Chinese rowers demonstrated their impeccable technique and stamina and that their remarkable performance set the tone for the rest of the day.

The Chinese wushu team displayed their agility, strength, and grace, captivating the audience with their breathtaking routines and clinching two gold medals in the men's Changquan final and women's Taijiquan and Taijijian all-round.

Winning the men's Changquan title, 34-year-old veteran Sun Peiyuan achieved his third consecutive Asian Games championships. He told the Global Times that he was excited after winning the title, despite enduring injuries during preparation for the Games. 

"I feel that all the efforts of me and the team, every point of hard work has been rewarded. I have lived up to the expectations of my country and my family," Sun said.

The shooting range also witnessed China's prowess as the country's shooters claimed a gold medal each in the 10 meters air rifle women's team event and 10 meters air rifle women's final. In the 10 meters air rifle women's final, China's 17-year-old Huang Yuting won with a 252.7 ring and set a new Asian Games record.

Powered by world champions such as butterfly queen Zhang Yufei, men's individual medley specialist Wang Shun as well as prodigy Pan Zhanle, the Chinese swim team secured seven gold medals in all seven competitions on the first day.

China's butterfly specialist Zhang eased to victory in the women's 200 meters butterfly with an Asian Games record of 2:05.57. 

Wang, who lit the Asian Games cauldron on Saturday night, was crowned the men's 200 meters individual medley champion after setting a new Asian record of 1:54.62 on Sunday. 

Freestyle prodigy Pan Zhanle smashed the men's 100 meters freestyle Asian record with a sensational 46.97 seconds, becoming the first swimmer in Asia to break the 47-second barrier. 

Distance swimmer Li Bingjie topped the women's 1,500 meters freestyle with a new Asian Games record of 15:51.18, while female breaststroke specialist Tang Qianting claimed the women's 50 meters breaststroke with 29.96 seconds.

Local favorite backstroker Xu Jiayu brought the tally to six as he won the men's 100 meters final with an impressive 52.23 seconds, also a new Asian Games record. 

The night culminated with Chinese female swimming quartet Yang Junxuan, Cheng Yujie, Wu Qingfeng and Zhang Yufei winning the women's 4x100 meters freestyle relay with an Asian Games record of 3:33.96.

Sunday was also the concluding day of the Hangzhou Asian Games's Modern Pentathlon competitions, with the Chinese team collecting gold medals in the women's individual and women's team final.

The Hangzhou Games are scheduled to end on October 8. As the Asian Games continue, all eyes will be on the Chinese delegation as they strive to maintain their dominance and add to their impressive medal tally. The athletes' exceptional performances on the first day have undoubtedly inspired their teammates and instilled a sense of confidence in the entire delegation.

32-year-old Portuguese golfer Ricardo Gouveia won his seventh Challenge Tour tournament at the Hainan Open in South China's Hainan Province on Monday after four days of competition.

He recorded a 272 (-16) to clinch the victory in four rounds, standing out from 120 players from home and abroad. Gouveia carded four rounds under par with a 67 in his first and final rounds, a 68 in the second round, and a 70 in the third round. He recorded 20 birdies in the tournament, highlighted by six in the final round on Monday.

"What an amazing day today. It was one of the toughest rounds of the year, and I played really well on the back nine. I just stayed patient throughout the day. I knew the last few holes were playing into the wind and really tough, so I'm excited to get the win," he said during an interview.

Switzerland's Joel Girrbach finished in second place on 13 under par, while Chinese player Ding Wenyi, Italian Francesco Laporta, and Englishmen Steven Brown and Will Enefer finished a shot further back in third.

The Islamic Republic has developed dozens of increasingly sophisticated turboprop and rocket-powered unmanned aerial vehicles over the decades, designed for missions ranging from reconnaissance to long-range precision strikes against land and sea targets.

Iran has reportedly developed a new hybrid aerial and sea-based drone capable of landing on and taking off from water, with senior military officials calling on Persian Gulf nations to ensure security collectively, while warning Washington and its allies of the consequences any aggressive moves.

"The Islamic Revolutionary Guard Corps Navy has built drones that can take off from and land on the water," IRGC Commander Ali Reza Tangsiri said in an interview with local media over the weekend, pledging that more details about the drone will be provided at a later date.

"The IRGC Navy has also built hybrid drones that fly with one engine, with the second engine serving as a propelling engine," Tangsiri said. That UAV is said to have the capability to carry out reconnaissance missions lasting up to 15 hours.

The water-landing drones, reportedly designed to be able to carry missiles and bombs, would dramatically enhance the IRGC Navy's already substantial naval and coastal defense capabilities in the defense of the nation's vast coastlines in the Persian Gulf, along the crucial world energy transportation chokepoint in the Strait of Hormuz, and in the Gulf of Oman.

Tangsiri reiterated Tehran's long-standing diplomatic stance that Persian Gulf security can be assured by regional countries, without any interference from non-Gulf countries, and proposed the creation of an eight-nation pact of Persian Gulf-adjacent countries to ensure regional security, including Iran, Bahrain, Iraq, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates.

The opportunities to forge such a regional security pact shot up dramatically this spring after Iran and Saudi Arabia signed a surprise normalization of relations deal mediated by China. Washington, Riyadh's longtime traditional partner in the region, was forced to begrudgingly accept the warming of relations between the traditional Gulf foes, while expressing skepticism over the agreement's ability to last, and leveling new sanctions against the Islamic Republic.

Separately, at a military ceremony outside Qom, central Iran on Monday, Iranian Armed Forces Chief of Staff Mohammad Baqeri warned Iran's potential enemies that the nation's military is on a hair-trigger alert to respond instantaneously to any aggression.

"The Iranian Armed Forces have set up a unified body to establish security in the country," Baqeri said. "State of readiness is a familiar concept for our armed personnel. That is, every moment we have our hands on the trigger and our eyes on the radar screen, along with surveillance and intelligence equipment so that no conspiracy is organized against the country and the enemies do not wish to launch aggression and undermine our security," the top commander added.

Also speaking at the event, Iranian Army Ground Forces Commander Kioumars Heidari warned that "if the enemies put a foot wrong and commit a foolish or mischievous act" against Iran, they "will receive a decisive response from the Army's ground forces."

"If the enemies attack Iran from the air, they will have no place to sit on the ground, and if they attack Iran from the ground, we will annihilate them within seconds by God's grace," Heidari added.

Iran unveiled a new ultra-long range drone last week at a military parade dedicated to the Iran-Iraq War of 1980-1988, with the UAV, named the Mohajer-10, capable of flying up to 2,000 km with a weapons payload of up to 300 kg, able to stay airborne for up to 24 hours at a time.

Regional tensions flared between the Iran and the US have recent months amid Washington's decision to dramatically ramp up its naval, air and troop presence in the Persian Gulf following Iran's crackdown on oil smuggling and maritime navigation violators.

Last month, IRGC Navy Commander Tangsiri stressed that the large US warships traversing Persian Gulf waters have been forced to obey Iran's maritime rules.

Armed with an impressive and technically advanced military-industrial complex, Iran's military design philosophy seems aimed at providing the country with David vs. Goliath-type asymmetric warfare capabilities against larger and technically more powerful adversaries, with the country building up mosquito fleets of fast boats armed with machineguns and artillery, hundreds of coastal defense batteries, dozens of drone designs, and maritime power projection capabilities using old tanker ships converted into mobile support platforms to save on costs. Iran's strategy has enabled it to become one of the top 20 militarily most powerful countries in the world, while spending just a fraction of what the US does on defense ($6.8 billion vs $877 billion in 2022).
