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.
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.
Zhang Xiaoning, Chairman of the China Golf Association, said that he is "looking forward to the return of the Hainan Open." The total prize money of this event has been upgraded to half a million dollars. It is the first highest-level international men's professional event held in China after the pandemic, which reflects the determination of the China Golf Association to further promote the development of golf.
A total of 50 Hungarian art works were featured on Tuesday at the Chongqing Art Museum. The 2023 Western China Hungarian Cultural Festival and the 2nd Chongqing Urban Arts Festival with the theme "The Journey: Janos Fajo and The Pesti Workshop," were co-organized by the Chongqing Art Museum, the Liszt Institute Hungarian Cultural Center Beijing, the Consulate General of Hungary in Chongqing, and Central Bank of Hungary. Czégel Bálint, consul general of Hungary in Chongqing, Kohári Lajos, head of Department at the National Assembly of Hungary, Wang Rongfa, director of Chongqing Art Museum, and other guests attended the ceremony.
This exhibition is to implement the Belt and Road Initiative (BRI) development strategy, strengthen the mutual understanding of civilizations and people-to-people communication with Belt and Road countries, and enrich the series of exhibitions of the 2nd Chongqing Urban Arts Festival to meet the high-quality spiritual and cultural needs of the public.
More than 50 pieces were put on display at the exhibition ranging from oil painting to printmaking and other media. The works are rich in context, experimental, and of high artistic value, reflecting the contemporary style and unique artistic characteristics of Hungarian contemporary painting.
The exhibition runs until November 17, according to official Wechat account of Liszt Institute Hungarian Cultural Center Beijing.
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).
China and Pakistan share a long-standing friendship that dates back to the early 1950s. Over the years, this relationship has evolved into a robust strategic partnership, with the two countries often being referred to as "iron brothers." In an exclusive piece penned ahead of the Third Belt and Road Forum for International Cooperation, the Prime Minister of Pakistan, Anwaar-ul-Haq Kakar, highlights the deep-rooted brotherhood and ironclad relations between China and Pakistan. He not only emphasizes the strength of bilateral ties between both countries, but also commends China's significant contributions to the global community.
By Anwaar-ul-Haq Kakar
The tale of China-Pakistan relations is not an ordinary one. It is an account of brotherhood, friendship, and trust, the foundations of which were laid more than 70 years ago. The vision of the leadership of our two countries at the time laid a solid basis for a relationship, which has subsequently been carefully nurtured into a robust, vibrant, time-tested, all-weather strategic cooperative partnership. Pakistan and its people, with absolute confidence, value the relationship greatly, and proudly call China our "best friend." It is heart-warming that in China, the term "Ba Tie" (Iron Brother) is reserved only for Pakistan.
The timeless Pakistan-China partnership and deep-rooted friendship serves the interests of both countries, being the historic choice of our people. Pakistan-China relations remain the cornerstone of our foreign policy. The close time-tested friendship with China enjoys the abiding support of the people of Pakistan.
With a time-honored history of brotherhood, our two countries have stood together, rain or shine, building an exemplary iron-clad friendship. Despite the vicissitudes of times and changes in the international landscape, the all-weather strategic cooperative partnership has grown into a towering tree with its deep roots of love in the hearts of the two peoples. The bond of love and affection that the peoples of the two countries have for each other indeed remains higher than the mountains, deeper than the sea, and sweeter than honey.
Zhou Enlai, China's first premier, once said that "the friendly interactions between the peoples of China and Pakistan date back to the dawn of history." Certainly, Pakistan-China relations are the continuation of ancient civilizational bonds that have existed between our two nations since ancient times. The flow of trade through the ancient Silk Road and geographical proximity brought the two great Asian civilizations together. Monks and thinkers from China made their historical journeys to Taxila and other Buddhist places in Pakistan, painting a beautiful picture of the Gandhara civilization and bringing Buddhist wisdom to China, thus binding the two nations together in an everlasting bond.
The historical evolution of the Pakistan-China relationship, and its growing importance in the wake of evolving regional and global developments, is an exemplary model of inter-state relationship. The unique relationship of more than seven decades, underpinned by the rationale of strong political support, mutual trust, and all-round practical cooperation, has matured into a strong strategic partnership.
I will soon be traveling to Beijing on my first visit after assuming office, to participate in the Third Belt and Road Forum for International Cooperation - an event which will mark the completion of a decade of the Belt and Road Initiative (BRI), the iconic and visionary project proposed by President Xi Jinping.
We pay tribute to the vision and statesmanship of President Xi who, 10 years ago, propounded the vision of building a global community of shared future, introducing a novel concept for international development partnership, a new idea for global governance and cooperation, and a fresh approach toward international exchanges, thus drawing up a new blueprint for a better interconnected world.
The core of the visionary concept is built on socio-economic development; with a focus on the elements of inclusivity, common prosperity, and win-win cooperation. It embodies the ideals of an open, interconnected, clean, and beautiful world that enjoys lasting peace and sustainable security. As we delve more into this concept, it becomes clear that it draws upon ancient Chinese philosophy and wisdom.
The concept of "tianxia datong," translated as "harmony under heaven," refers to the whole world and promotes diversity, while emphasizing harmonious and mutual interdependence as the means to enduring peace.
As noted by the recent BRI white paper released by the China's State Council, the BRI is a key pillar of the global community of shared future. The subsequent unveiling of the concepts - including the Global Development Initiative (GDI), the Global Security Initiative (GSI), and the Global Civilization Initiative (GCI) - have further refined the concept of a global community of shared future.
Pakistan was among the first countries to join the BRI. As the flagship project of the BRI, the China Pakistan Economic Corridor (CPEC) marks a milestone in Pakistan-China relations, by placing economic cooperation and connectivity at the very center of the bilateral agenda, making the two countries more interconnected than ever before. The CPEC remains a shining example of the BRI's promise of economic prosperity and connectivity. It has transformed the socio-economic landscape of Pakistan, upgrading modern infrastructure, enhancing regional connectivity, ensuring energy security, and creating jobs.
This year Pakistan hosted a series of events and activities marking the successful first decade of the CPEC. We were also pleased to welcome Chinese Vice Premier He Lifeng, the special representative of President Xi, in Pakistan to attend the Decade of CPEC celebration event.
Pakistan remains committed to jointly building the CPEC. We fully endorse China's proposal of developing the CPEC as a corridor of growth, livelihood, innovation, greenness and openness - representing our two countries' preference for a human-centric approach, inclusivity, and green development.
Pakistan is also a pioneering member of the Group of Friends of the Global Development Initiative (GDI) and has played an active role in giving it a more concrete shape. As the first priority partner under the GDI, and the first one to ink an MoU on the GDI, Pakistan stands ready to benefit from this cooperation in areas of education, healthcare, climate change, and poverty reduction, thus making meaningful contributions to achieving the Sustainable Development Goals in a timely manner.
Pakistan has also supported the Global Security Initiative and its adherence to the UN Charter and principles of multilateralism and non-interference in other countries' internal affairs. Having long suffered due to unresolved disputes, conflicts, and terrorism, we also advocate for dialogue and constructive engagement based on mutual respect, to ensure regional peace in South Asia.
The Global Civilization Initiative is yet another landmark and timely initiative proposed by President Xi, promoting respect for diversity, peaceful co-existence, mutual learning, and inclusiveness. In a world marred with discord and divisiveness, dialogue between civilizations can be a means to peace and reconciliation.
Pakistan's foreign policy objectives have always been those of "peace within and peace without," as outlined by our founding father Muhammad Ali Jinnah. It was, therefore, all but natural for Pakistan to endorse these key initiatives put forth by President Xi.
In a world marred by multiple challenges like conflicts, economic recessions, food insecurity, social inequalities, and climate change, the salience of the Pakistan-China all-weather strategic cooperative partnership assumes great importance.
It is a source of pride and comfort for our two peoples and a factor of peace and stability in the region and beyond. Ours is a relationship of the past, present, and future, and nothing can alter this reality.
As per our long-standing tradition, we support each other on our core issues. We are grateful to China for its support for Pakistan's sovereignty, territorial integrity, and economic security, and its principled support on the issue of Kashmir. We reaffirm our commitment to the one-China principle and our support to China on its core issues related to Taiwan, Hong Kong, Xizang (Tibet), Xinjiang, and the South China Sea.
As close friends, strategic partners, and iron brothers, Pakistan and China are moving forward toward a destiny of shared future. I remain confident and convinced that our friendship will further strengthen in the coming days and attain even greater heights in the years to come.
136 types of seeds, including crops, forest vegetation, flowers, and microorganisms will be carried on board the Shenzhou-16 manned spacecraft to start their space breeding journey. These seeds will contribute to the advancement of China's agricultural science and technology and enhance food security, the China Manned Space Engineering Office announced on Wednesday in a statement.
The seeds were selected through a four-month application and review process and have been chosen from 53 institutions across the country. The project, conducted by manned spaceflight, is of a public welfare nature and does not charge any carrying fees.
It has been 36 years since China's first space seed breeding effort in 1987, the country has sent the seeds of hundreds of plant species into space on dozens of retrievable satellites and Shenzhou spaceships. Nearly 1,000 new species have been created, of which 200 have displayed outstanding performances, according to media reports.
Space seed breeding uses cosmic radiation to mutate the genes of seeds sent into space, in order to create new species for greater variety.
"Space peppers and watermelons" commonly found in supermarkets in China are successful varieties of space breeding. China ranks first in the world in the number of cultivated varieties and the range of popularization and application of space breeding, read media reports.
The area under cultivation for grains, vegetables, fruits and other plants developed by space seed breeding has surpassed 4 million hectares, and generated economic benefits of over 200 billion yuan ($30.51 billion), media earlier reported.
The seeds need further improvement, especially in disease resistance, through conventional breeding methods or space breeding, the Xinhua News Agency reported.
Space breeding involves exposing seeds and strains to cosmic radiation and microgravity during a spaceflight mission to mutate their genes.
China's space seed breeding level also reflects the nation's advancing aerospace technology, Li Guoxiang, a researcher at the Rural Development Institute of the Chinese Academy of Social Sciences, told the Global Times.
"There are only a few countries in the world with mature aerospace technology, and Chi
For corals, baby fat is food. Coral mothers send their offspring into the world with a balanced meal of fat and algae, but baby corals mainly chew the fat, new research finds.
Adult corals of the species Pocillopora damicornis get most of their nutrition from symbiotic algae that live inside them, providing metabolic energy by photosynthesis. But coral larvae, researchers report online March 25 in Science Advances, rely instead on their “baby fat.”
The finding sheds light on corals’ metabolism during their most vulnerable developmental stage, says biological geochemist Anders Meibom of École Polytechnique Fédérale de Lausanne in Switzerland. Baby fat “is a good thing,” he says. “It gives the coral some time to find a good home without running out of juice.” Larvae’s dependence on fat may make them less sensitive to bleaching — a process in which stressed corals jettison their algal tenants and eventually starve to death. So understanding larval nutrition could help scientists better understand the effects of ocean warming and acidification on bleaching, Meibom says. Meibom and colleagues fed isotope-tagged nutrients to larvae of P. damicornis, commonly called cauliflower coral, and tracked how the larvae’s symbiotic algae used the nutrients over time. Algae are less abundant in larvae compared with adult corals and provide very little energy, the researchers found.
The next step is to pinpoint exactly when and how larvae switch from feeding on fat to algae as they transition into adulthood, Meibom says, as well as exploring how Earth’s changing oceans might impact the process.
Ocean outlook Earth’s oceans are a hot mess. They absorb heat at twice the rate that they did nearly 20 years ago, Thomas Sumner reported in “Ocean heating doubles” (SN: 2/20/16, p. 18). Meanwhile, phytoplankton release more heat during photosynthesis than previously thought, Chris Samoray reported in “Ocean flora flunk photosynthesis test” (SN: 2/20/16, p. 12). And the trillions of plastic particles littering the oceans are creating new habitats for microbes with unknown consequences, Samoray wrote in “Floating fortress of microbes” (SN: 2/20/16, p. 20). Anna Carter wondered if these findings are connected. “Is it possible that phytoplankton are contributing to ocean warming?” Carter asked. “How might the organisms now collecting on all the plastic in the ocean be related?”
Heat produced by phytoplankton doesn’t have a large impact on ocean temperature, says Sumner. “The phytoplankton are catching sunlight that otherwise could warm the water,” he wrote. “Another thing to keep in mind is that the oceans are colossal. At its deepest, the Pacific Ocean is about as deep as the cruising altitude at which most commercial airliners fly. Phytoplankton live in the top sliver of the water column, so any effect they have will be minuscule compared with the size of the ocean.” As for plastic-dwelling microbes, there is still so much to discover, Samoray says. Their contribution to ocean warming is currently unknown.
Ants on the move Florida harvester ants may be the Frank Lloyd Wrights of the animal kingdom. They construct intricate and mysterious nests, Susan Milius reported in “Restless architects we don’t understand” (SN: 2/20/16, p. 4). Researchers investigated why ants frequently build and abandon elaborate nests, and scatter charcoal around nest openings.
Readers had their own ideas about the unusual behavior. “[Charcoal] is an effective absorber of organics. Is it possibly used for absorbing their scent as a protective measure against predators?” Mark Ayers asked.
Walter Tschinkel, the Florida State University scientist featured in the story, says that the scorched plant matter ants use may not be as effective for these purposes as commercial charcoal. Field tests found no sign that charcoal would deter attacks by other ants.
Reader Joe De Vita speculated that colonies abandon their nests because of waste buildup. Tschinkel notes that this hypothesis has yet to be tested. “Digging up the vacated nest often reveals chambers with matted, blackened floors, presumably from fungus and other microorganisms, but whether this condition has any negative (or for that matter, positive) effects on harvester ants is unknown,” he says. An experiment to test this hypothesis is possible, but “ain’t all that easy. Still, stay tuned.”
Milk for spills Researchers have created a fibrous membrane made from milk proteins and carbon that could filter toxic heavy metals from severely polluted waters, Sarah Schwartz reported in “Altered milk protein cleans up pollution” (SN: 2/20/16, p. 14). In lab tests, the membrane removed over 99.9 percent of lead from a contaminated solution.
“It is a very exciting method,” wrote Janece Von Allmen. “Has anyone thought to test this method in the real polluted waters of Flint, Michigan?”
The filters are still in an early stage of design, Schwartz says. The membranes work in the laboratory to capture heavy metals and radioactive particles, but testing in the real world is a must. “Bodies of contaminated water are most likely chemically different from lab-made lead solutions and could change the membrane’s performance,” she says.
Whether or not these membranes would work in the Flint River is unclear because the river is not the original source of lead. The toxic heavy metal accumulates as the water passes through corroding pipes. The good news is the prototype shows signs of being efficient and is relatively cheap to produce.
