Chinese research team proposes "Future" chip: computing power up to 3,000 times higher that of current high-performance commercial chips

In the science fiction movie "The Wandering Earth," artificial intelligence system "Moss" is able to explore all solutions to save the Earth in just a few seconds.

This miraculous scene is gradually transitioning from science fiction to reality. The ultra-high-performance optoelectronic chip proposed by the research team at Tsinghua University adopts a new architecture of optoelectronic fusion, which is disruptive to existing chip technologies, the team told the Global Times on Wednesday.

The technology not only opens up a new path for this future technology to become part of daily life, but also provides inspiration for the integration of other future high-performance technologies such as quantum computing and in-memory computing with current electronic information systems.

The results, titled "Purely Analog Optoelectronic Chips for High-Speed Visual Tasks," had been published in the recent issue of the journal "Nature."

In 1965, Gordon Moore, one of the founders of Intel, proposed "Moore's Law," which has influenced the chip industry for over half a century. It predicts that the number of transistors on integrated circuits will double approximately every two years.

The semiconductor field has prospered for decades based on Moore's Law, and "chips" have become an important engine for humanity's entry into the era of digital intelligence. However, as transistor sizes approach their physical limits, Moore's Law has slowed down or even faced failure in the past decade. How to build a new generation of computing architecture and establish a "new" order of chips in the era of artificial intelligence has been a frontier hotspot of international concern.

To address this challenge, a joint research team from Tsinghua University, including Academician Dai Qionghai from the Department of Automation, Assistant Professor Wu Jiamin, Associate Professor Fang Lu from the Department of Electronic Engineering, and Associate Researcher Qiao Fei, proposed a new computing architecture that "breaks free" from Moore's Law: optoelectronic analog chips. In practical tests for visual tasks, the computing power of these chips reached over 3,000 times that of current high-performance commercial chips.

From a physical perspective, optoelectronic chips are based on a disruptive technology that is different from existing chip technologies, the research team explained in an interview with the Global Times on Wednesday. They noted that, at current stage, their work is focused on intelligent visual tasks, and they are also conducting further exploration to see if the new technology can achieve tasks of the same or even higher complexity as current chips, such as large language models.

In this small chip, the Tsinghua University research team creatively proposed an optoelectronic deep fusion computing framework. Starting from the most fundamental physical principles, it combines optical computing based on electromagnetic wave propagation in space with pure analog electronic computing based on Kirchhoff's law. It "breaks free" from the physical bottlenecks of data conversion speed, accuracy, and power consumption that constrain traditional chip architectures, and overcomes three international challenges: large-scale computing unit integration, efficient nonlinearity, and high-speed optoelectronic interfaces.

In the demonstrated intelligent visual scene tests in the paper, the system-level computing power of the optoelectronic fusion chip was thousands of times higher than that of existing high-performance chip architectures. However, such astonishing computing power is just one of the many advantages of this chip. In the intelligent visual tasks and traffic scene calculations demonstrated by the research team, the system-level energy efficiency (the number of operations that can be performed per unit of energy) of the optoelectronic fusion chip reached 74.8 Peta-OPS/W, which is over 4 million times that of current high-performance chips. In other words, the amount of electricity that can power existing chips for one hour can power this chip for over 500 years.

One key factor currently limiting chip integration limits is the heat dissipation problem caused by high density. The optoelectronic fusion chip, which operates at ultra-low power consumption, will greatly improve the chip's heat dissipation problem and bring all-round breakthroughs to the future chip design. Furthermore, the minimum linewidth of the chip's optical part is only in the hundreds of nanometers, while the circuit part uses 180 nanometers Complementary metal-oxide-semiconductor technology, achieving a performance improvement of multiple orders of magnitude compared to 7 nanometers process high-performance chips. At the same time, the materials used are simple and easily obtainable, and the cost is only a fraction of the latter.

Will the emergence of this cutting-edge chip technology help China achieve a "overtaking on the curve" in chip research and development? In response to this question, the research team told the Global Times that the research and development competition in the traditional chip technology field is becoming increasingly fierce, and facing international challenges such as the slowing down of Moore's Law, the world is seeking new computing architectures. It can indeed be understood as a kind of "curve" opportunity. Whether we can achieve "curve overtaking" depends on the joint efforts and ecological construction of all sectors. We are also working towards this goal.

A special review of this research, invited by the journal Nature, pointed out that the appearance of this chip may allow the new generation of computing architecture which will be integrated into daily life much earlier than expected. Academician Dai Qionghai, one of the corresponding authors of the paper, stated, "Developing a new computing architecture for the era of artificial intelligence is a summit, but truly implementing the new architecture in real life to solve major national and livelihood needs is a more important challenge and our responsibility."

GT investigates: Who is the black hand behind conspiracy to smear 'Overseas Police Service Station' and attack China?

It was reported recently that the US Department of Justice arrested two Chinese residents in New York on suspicion of setting up a "secret police station" in Manhattan for the Chinese government to suppress so-called "dissidents." According to the indictment, they were arrested for operating an "Overseas Police Service Station," which is, in fact, just a volunteer service platform for overseas Chinese in Manhattan, New York. 

The news caught the attention of overseas Chinese groups. Many overseas Chinese who have sought help from such volunteer service platforms expressed their incomprehension and indignation, and called for justice to be served for such volunteer service platforms on the internet. However, the volunteer service platforms, named "Overseas Police Service Stations," are shuttering their doors due to the vicious defamation, causing great inconveniences for overseas Chinese nationals.

Analysts pointed out that the US, which calls itself the "beacon of human rights," is once again ignoring the fact and conflating issues, leading many to suspect that such actions have a nefarious purpose behind them. 

Through an in-depth investigation, Global Times reporters found out that Safeguard Defenders, an organization funded by an ex-con with a criminal record and engaged in aggressive anti-China defamation, is behind this conspiracy as part of its efforts to smear and attack China. Some Western politicians and media outlets have deliberately spread a false report by the Safeguard Defenders on the so-called "secret police station" as a means to attack China. 

People familiar with the matter told the Global Times that the functions of the Chinese police force in China are different from those in the West, and the Safeguard Defenders' bad faith actions to deliberately encourage misguided public opinion will be despised by the international community.

What is the "Overseas Police Service Station"? Who are the conspirators? What are their dark purposes? In this piece, Global Times reporters will unravel these mysteries and shed a light on the vicious plot of the organization.

Volunteer platforms to assist overseas Chinese

"Overseas Police Service Stations" are volunteer platforms established by overseas Chinese groups to assist Chinese nationals in seeking services from competent and relevant departments in China online, according to public materials. 

For example, many overseas Chinese who have worked abroad for many years need to return to China to undergo physical examinations to extend their driving licenses. However, due to prohibitive costs, as well as being time- and energy-consuming to return to China, they often turn to local overseas Chinese groups, hoping for alternative assistance from relevant departments in China.

At the request of overseas Chinese, some enthusiastic overseas Chinese groups and chambers of commerce voluntarily founded such mutual-aid platforms.

Why then would such voluntary service centers be labeled "police service stations"? In China, the formal name of the police force is the "People's Police," whose mission is to serve the people. Therefore, different from their counterparts in many other countries, the Chinese police are also tasked with fulfilling many diverse administrative functions such as approving and issuing household registration documents, the issuance of driving license, as well as traditional law enforcement. 

The term "Overseas Police Service Station" alludes to the voluntary service stations' active role in bridging the gap between overseas Chinese in need of services and Chinese police-designated service delivery such as the extension of driving licenses.

Mr Lu, an overseas Chinese national who has been conducting business in a foreign country for over 10 years, has much to say about these volunteer service platforms established by overseas Chinese groups. 

In September 2021, Lu was in a dilemma, as he could return to China to undergo a physical examination needed to renew his expiring driving license due to the global COVID-19 pandemic. A packed business schedule, coupled with the exorbitant cost and time demands of a round trip to and from China, was also prohibitive factors. So he had to turn to the Overseas Chinese Association. 

The person in charge of the Overseas Chinese Association told him of the decision to establish a service platform to help bridge communication and service delivery between overseas Chinese and relevant Chinese governmental departments. This, he was informed, had been necessitated by the large number of overseas Chinese in a similar predicament as him. 

"The service platforms provide services free of charge, and the service personnel there are all volunteers. You can apply for a physical examination online through the volunteer service platform," Lu explained.

With the assistance of the service platform, Lu successfully completed the physical examination to help renew his driving license in time.

Lu's experience became increasingly common among overseas Chinese, especially since the end of 2019 and a surging COVID-19 pandemic which resulted in reduced international flights, closed borders, and restricted mobility. For ordinary overseas Chinese, it is both time- and energy-consuming to apply for a physical examination needed to renew their driving licenses in China, hence the need for such volunteer platforms.  

According to statistics, more than 60 million Chinese nationals are living in almost 200 countries and regions around the world, who actively contribute to their host countries' societies and economies. 

Such service platforms have met the practical needs of overseas Chinese, winning extensive praise from overseas Chinese communities worldwide. It is obvious that such stations and similar platforms are volunteer organizations willingly formed by overseas Chinese with the help of local Chinese groups, intended to provide overseas Chinese in need with advise and practical assistance, a source close to the matter told the Global Times. 

Like most countries, the relevant departments of the Chinese government not only handle certificate applications and consultations on site, but also receive application documents remotely. After living and working abroad for extended periods of time, some overseas Chinese are not familiar with online application or submission processes related to their requests in China, as well as not familiar with domestic requirements or procedures, thus face difficulties in handling such submissions unassisted. 

The service stations provide voluntary consultation and assistance, not only solving the urgent needs of local Chinese, but also helping domestic administrative departments serve overseas compatriots. Overseas Chinese are enthusiastic about providing voluntary services to assist their compatriots in the service stations; they are neither paid nor employed by any Chinese authorities, the source said.

The service stations do not have any right to offer any administrative services. Such mutual-aid volunteer platforms formed by overseas Chinese by no means violate international or domestic laws, or infringe on the sovereignty of the host country, the source stressed. 

Mei Jianming, a professor from the Shanghai University of Political Science and Law and former deputy dean of the anti-terrorism department at the People's Public Security University of China, told the Global Times that "serving the people wholeheartedly" is the purpose of China's public security organs. To realize this purpose, the public security organs in China assume two major functions - law enforcement and social service. 

In China, there is a saying that "if you have difficulties, you can go to the police." When ordinary people encounter various problems in their lived, such as not being able to open doors, or needing help to carry gas tanks, they will immediately think of turning to the police for help, which is very different from Western society, Mei said.

The "Overseas Police Service Stations" are actually set up to meet the needs of Chinese expatriates. Because it is different from the Western police system, it is objectively not easily understood by the local people, and subjectively is easy for some people with ulterior motives to fabricate rumors regarding their purpose, he noted.

Vicious anti-China NGO

Where did the absurd term "secret police station" come from? A quick internet search reveals that the term comes from a report released by the NGO "Safeguard Defenders," in September 2022. The report falsely claimed that these service stations are "secret police stations" and engage in the deliberate misinterpretation of public reports on Chinese media as so-called proof.

Soon after the report was released, a few of countries began to attack and defame these service platforms, and even launched investigations, sought prosecution, and engaged in other law enforcement activities against relevant overseas Chinese leaders.

A source familiar with the infamous Safeguard Defenders pointed out to the Global Times that it is an organization funded by an ex-con with an extensive criminal record and is engaged in aggressive anti-China defamation campaigns, releasing untrustworthy reports to spread rumors about China in an attempt to slander the country. 

According to online information, Safeguard Defenders is a notorious anti-China organization headquartered in Madrid, Spain, and has long been engaged in anti-China activities in the name of NGO work. 

Its leader, Peter Jesper Dahlin, had long been engaged in activities meant to compromise China's national security since 2009, and was investigated and deported by the Chinese law enforcement authority in 2016 for endangering Chinese national security. However, Dahlin has since remained impenitent and stepped up his efforts after being deported, the source said. 

After founding the Safeguard Defenders in Europe in 2016, Dahlin wantonly attacked and defamed China's judicial systems and law enforcement activities, and released so-called investigation reports that distort and slander judicial enforcement activities in China on multiple occasions with a view to take revenge on China. 

Experts have pointed out the inaccuracies and blatant lies in all its reports on China's judicial systems. 

If these "Overseas Police Service Stations" were "secret police stations" as indicated in the so-called report by the Safeguard Defenders or labeled by certain media outlets and western politicians, then China's extensive media coverage of them would be counterintuitive. The Safeguard Defenders has also claimed that these service stations have been established in 53 countries since 2016, widely publicizing this information. Such claims beg the question why such "secret police stations" would go unnoticed by host governments over the last seven years despite being publicized. 

According to the Safeguard Defenders' so-called report, the repatriation of Chinese overseas fugitives to China is also aided by these "Overseas Police Service Stations" rather than by bilateral and multilateral law enforcement cooperation between China and other countries, implying disproportionately great power and influence allegedly possessed and wielded by mere volunteers. 

Mei told the Global Times that some foreign NGOs often have their own positions and preferences. The motivations and position of the Safeguard Defenders are not objective, and the credibility of the so-called report issued by the organization is doubtful.

He pointed out that the Safeguard Defenders may be aware of the differences between the police system in China and those in Western countries, but deliberately use the lack of public awareness to amplify malicious disinformation that leads the misguided public opinion.

Diabolical campaign

After the so-called report by the Safeguard Defenders was released, some foreign media sources cited the Safeguard Defender's false information in their own reporting, further spreading misinformation among people who don't know the real situation regarding China and the "Overseas Police Service Stations," negatively affecting public opinion. 

Some bad faith actors in the media have directly cited false information and stirred up trouble to increase content consumption through increased circulation or improved audience ratings. A few such media sources, without conducting due diligence or verification, have linked the "Overseas Police Service Stations" to the international law enforcement cooperation conducted by China according to bilateral agreements and international conventions with overseas service stations, and spread rumored that the Chinese police force is engaged in fugitive hunting or other law enforcement activities through these stations.

In an interview with ANSA, famous Italian sinologist Daniel Buligado Colonia strongly refuted the existence of so-called "secret police stations" and noted that individuals working at the "Overseas Police Service Stations" were not police. The sinologist further added that "the Chinese government would not be reckless enough to allow flagrant violations of other countries' sovereignty." 

Overseas Chinese in many countries also support such volunteer service platforms through various channels, and hope that host governments will fully consider the practical difficulties of overseas Chinese in returning to China. They called for an end to speculations around the volunteer service platforms.

Li Wei, an expert on national security at the China Institute of Contemporary International Relations, told the Global Times that for the so-called anti-China political purpose, some officials and politicians in the US and other countries blindly accepted the contents of the report, without conducting investigations or verifying the information contained therein. They actively aligned themselves with the report in order to gain political capital.

Li said that in this era of globalization, the exchanges and cooperation between people of different countries in education, tourism, trade, and other fields are getting closer and closer, and overseas Chinese nationals need more and more services from their own governmental departments. 

The "Overseas Police Service Stations" are keen to provide voluntary services for local overseas Chinese nationals. It is reasonable and legal and should have become a model for overseas Chinese groups in various countries. However, the so-called report which is full of inconsistencies has triggered malicious speculation and political manipulation. The dark motives behind the report should raise people's awareness and be a cause for concern, he warned.

Mid-Autumn Festival and National Day holidays boost tourism and consumption across China

Over the past eight days, people in China enjoyed a vacation that combined the Mid-Autumn Festival and the National Day. People chose to spend the holiday in various ways, showcasing a surge in travel and consumption.

Over the first five days of the Mid-Autumn and National Day holidays, key business districts across the country were bustling with activity. According to data from the Ministry of Commerce, foot traffic in key business districts in 36 major cities nationwide increased by 150.4 percent compared to the same period in 2022. 

According to consumption data for this year's Mid-Autumn and National Day holidays compiled by Meituan, daily average consumer spending across the country increased by 153 percent compared to the same period in 2019, marking it the most prosperous holiday season in five years. Among the top five cities in terms of consumer spending were Shanghai, Beijing, Chengdu, Chongqing, and Shenzhen.

On October 1, the highly anticipated National Day flag-raising ceremony took place at the Tiananmen Square in the center of Beijing, drawing hundreds of thousands of people from all over the country to celebrate the 74th anniversary of the founding of the People's Republic of China. 

Zhang Yunyi, a resident of Beijing, booked his ticket for the flag-raising ceremony a week in advance and arrived at Tiananmen Square in the early hours of the morning, waiting for five hours in the pre-dawn darkness. 

"The wait was long and the night was cold, but when I finally saw the national flag slowly rise along with the national anthem, it filled my heart with deep emotion," Zhang told the Global Times.

After the flag was raised, doves symbolizing peace were released, eliciting cheers from the onlookers.

In Hangzhou, East China's Zhejiang Province, the combination of the extended holiday and the Asian Games sparked a tourism boom. Data from multiple online travel agency platforms showed that hotel bookings in Hangzhou from September 23 to October 8 increased more than eightfold compared to the previous year, while ticket bookings spiked nearly twelvefold, CNR reported.

In Chengdu, Southwest China's Sichuan Province, even the pandas were busy welcoming visitors. During this year's Mid-Autumn and National Day holidays, the Chengdu Research Base of Giant Panda Breeding had limited daily ticket availability, with only 60,000 tickets available each day. Tickets for the panda base were consistently sold out, making it quite challenging to catch a glimpse of the superstar panda, Hua Hua.

Many people also chose to travel abroad, marking a significant resurgence in the outbound tourism market. On Fliggy Travel, bookings for outbound travel during the Mid-Autumn and National Day holidays increased by over 20 times compared to the previous year, setting a new annual peak in outbound travel. Popular destinations included Thailand, Malaysia, South Korea, Australia, and Indonesia, while Egypt, New Zealand, Vietnam, Turkey, and Spain showed the fastest growth rates, according to Economic Daily.

Back on domestic social media networks, a trend called the "24-Hour Gourmet Challenge" or "Special Forces-Style Travel" has emerged, where participants attempt to sample all the local delicacies of a city within 24 hours.

Reality and delusion of India’s ‘great power dream’ from G20 New Delhi Summit

After marathon negotiations, the G20 summit held in New Delhi, India, finally managed to reach a joint declaration on September 10, avoiding the embarrassment of a fruitless summit. The Finance and Central Bank Deputies Meeting and Foreign Ministers' Meeting hosted by India before the summit failed to produce a decent joint declaration, highlighting the significant differences in positions and opinions among the countries as well as the Indian government's struggle to deal with a divided world.

The joint declaration of this summit once again clarifies the positioning of the G20 as "the premier forum for international economic cooperation," and it states that "while the G20 is not the platform to resolve geopolitical and security issues, we acknowledge that these issues can have significant consequences for the global economy." G20 members have reached a consensus and invited the African Union (AU) to become a formal member of the mechanism. This can be seen as a "rectification" to counter the attempts by the US and the West to hijack the G20 summit agenda, as well as a response from developing countries and the Global South.

Despite the discontent in Ukraine and the difficulty of reaching consensus, Western diplomats were willing to "let through" the declaration's wording on the Russia-Ukraine conflict, probably believing it was a price worth paying. Aljazeera commented that "many Western countries, concerned about China's rising power, want New Delhi - a strategic counterweight to Beijing - to be able to claim this summit was a great success."

Inviting the AU to join the G20 is an important outcome of this summit. As the largest developing country and a member of the Global South, China was the first country to explicitly express its support for the AU's membership in the G20. Of course, India's efforts to include the AU may imply a calculation to win the support of African countries for India's bid for permanent membership in the UN Security Council.

Since taking over as the rotating chair of the G20 summit in December last year, the Modi administration has regarded the G20 summit as a "golden opportunity" to confirm India as a "global leading power." It also intends to turn this into a major diplomatic achievement domestically and use it as an opportunity for the Bharatiya Janata Party (BJP) to campaign for next year's general elections.

At the same time, India sees itself as a bridge between the "Global South" and the "Global West." The External Affairs Minister of India, Subrahmanyam Jaishankar, said India has the potential to become "a bridge between the established and emerging orders."

However, India's dream of being a great power is idealistic, but the reality and setbacks it encounters are cruel. From the beginning, India has been under pressure from the US and the West, demanding condemnation of Russia at the G20 summit. New Delhi wants to maintain its special partnership with Moscow, while also trying to please the US and the West and act as the spokesperson for the "Global South." Meanwhile, the current administration wants to campaign for the BJP in next year's general elections. It is obvious that India expects too much from the G20 summit.

It is understandable that India wants to use the G20 summit stage to demonstrate its status as a major power and shape an international order that is favorable to itself. 

However, the excessive political calculations and geopolitical considerations introduced into the G20 summit agenda have led to reduced expectations from relevant countries and have deprived the international community of an opportunity to concentrate on substantively addressing global challenges such as food and energy crises.

China and India have had good cooperation in many areas. However, in recent years, India has deliberately highlighted its differences with China in such areas as regional and global governance as well as sustainable development, with the intention of marginalizing China from the Global South community. New Delhi's practice of undermining developing countries' unity and cooperation and boosting itself by belittling other countries deserves vigilance. It is destined to be recorded in the history of the G20 New Delhi Summit and reflects the delusional side of India's dream of becoming a major power.

Whether EU can ‘reduce perception of risk’ depends on its attitude toward protectionism

While EU's trade chief Valdis Dombrovskis urges China to do more to help "reduce the perception of risk," there are multiple signs that bilateral economic ties are embarking on fast-track development. Obviously, the European business community hopes EU's priority is to promote cooperation, rather than "de-risk" its relationship with China.

Amid global uncertainty, European and Chinese senior officials held high-level economic and trade talks on Monday. Despite some disagreements which are continually hyped up by some EU politicians, the high-level trade talks serve as a good opportunity for China and the EU to enhance communication and understanding.

Ahead of the dialogue, some statistics showed German companies continue to invest heavily in China despite calls from a number of German politicians to reduce their exposure in China. Investment in China as a share of Germany's overall investments increased to 16.4 percent in the first half of this year from 11.6 percent in 2022 and 5.1 percent in 2019, Reuters reported on Wednesday, citing data from the German Economic Institute, a private economic research institute in Germany.

Germany has been Europe's economic engine for decades. However, persistent inflation has pushed the German economy into a technical recession with data showing that the economy contracted in the first quarter of 2023. Overall, German direct investment outflows dropped sharply, to 63 billion euros ($67 billion) in the first half of 2023 from 104 billion euros in the first half of 2022. 

At a time when Europe's largest economy is battling recession, the Chinese economy offers opportunities for German enterprises. That's why in spite of the so-called decoupling or de-risking rhetoric made by some Western officials, European investments continue to pour into China. 

It is worth noting that there is a trend that the more open China becomes, the more vigilant the EU has become against China. It is true that economic and trade disputes exist in China-EU relations. The European Commission launched an investigation on September 13 into whether to impose additional tariffs to protect EU producers against cheaper Chinese electric vehicle (EV) imports it says are benefiting from the so-called state subsidies. Trade protectionism could be a double-edged sword for bilateral relations, as China is now an important overseas market for European enterprises.

Dombrovskis said in a speech he delivered at Tsinghua University in Beijing on Monday that Europe's economic ties with China are deep, but China "could do a lot to help reduce our perception of risk," according to a Reuters report. The report said the EU has long complained about "a lack of level playing field in China" and "the politicization of the business environment," which is mainly a Western narrative to sow discord and to pressure China to give foreign investors supernational treatment. 

As a matter of fact, Europe is the party that adopts protectionist measures to disrupt economic and trade cooperation. China welcomes investment from European countries, but the ball is in the European's court to break down barriers over mutually-beneficial economic cooperation. The best way to help reduce European perception of risk is to put geopolitical thinking aside, stop adopting protectionist measures, fully consider the feelings of European companies, and resolve each other's concerns through dialogue and consultation.

Monday's dialogue, the first in-person meeting post-pandemic, has drawn wide attention. It's impossible to solve each and every problem overnight, especially amid the "decoupling" calls and the instigations by the US, but achievements will add up through frank dialogues and communications, pushing forward China-EU economic ties.

Monday's trade talks won't become the endpoint for both sides to seek common ground and solutions to resolve differences and problems. Future efforts should be made and the European side should take more responsibility, as it is the party bowing to trade protectionism. Whether it can "reduce the perception of risk" depends on Europe's attitude toward trade protectionism.

Airbus helps propel sustainable energy transformation in civilian aviation: executive

Airbus is playing a role of "catalyst" in Chinese market for the development of sustainable aviation fuel (SAF) industry, propelling sustainable energy transition in civilian aviation sector to realize decarbonization targets, an executive from Airbus said in Beijing on Tuesday.

Airbus is working on a number of levers, so the first one is technology and fleet renewal. The company is also working actively on improving the efficiency of operations. And the third and very big one is the energy transition of which SAF is a key topic, Julie-Kitcher, Executive Vice President of Airbus said.

The comments are made as more Chinese airlines vowing to promote use of sustainable aviation fuel. In October of last year, Airbus said its Tianjin plant delivered an A320neo to China Eastern Airlines that used five percent SAF as the fuel during its delivery flight.

SAF is a sustainable aviation fuel made from feedstock ranging from used fat, oil and grease to municipal and forestry waste. Compared to fossil jet fuel, SAF has been demonstrated to result in an up to 80 percent reduction in CO2 emissions. Therefore, it is considered as a key enabler to contribute to the de-carbonization of aviation sector.
And so when talking about SAF, there's a huge capability in China with feedstock in abundance, technology and innovation and in fact, China has been supporting certification since 2008 in different ways. All the airlines have expressed interest in environmental matters on sustainability, SAF in particular, Kitcher said.

And Airbus is working with China National Aviation Fuel Group Corporation to develop the SAF industry or act as a catalyst in China, she added.

In July of last year, the Airbus Lifecycle Services Center project broke ground in Chengdu, Southwest China's Sichuan Province. The project is Airbus' first aircraft lifecycle service project outside Europe. The company said the project has moved from the planning stage to construction and the aim is for it to enter into service by the end of 2023.

Airbus is spending around 2 billion euros per annum on R&D, which is mainly targeting sustainable aviation. All partners and players will need to make significant investments for their respective licenses to continue to operate. Aircraft manufacturer need to really look at the overall lifecycle of the aircraft, so it's from design, supply chain, the operations, the maintenance, and the end of life recycling, Kitcher said.

To show the conviction in terms of the necessity to decarbonize the sector, Kitcher said that they're working on different levels for the industry, including the technology starting with fleet renewal and enhancing and improving the efficiency of air traffic management operations.

She also said to enhance the energy transition, which means to increase the adoption of SAF, Airbus targets to certify all its aircraft with 100 percent SAF capability by the end of this decade, adding that the company is also developing hydrogen technologies for future use.

Airbus is aiming to reach a global 10 percent target by 2030, which is around 34 million tons of SAF by 2030.Actual demand for probably around 20 million tons are committed. So "we still have progress to make, but we're confident that collectively we can get there", she said.

Travel heat continues as 'Golden Week' enters fourth day

Travel heat continued to spread nationwide. The number of railway trips made by Chinese passengers is expected to hit 16.40 million on Monday, the fourth day of eight-day-long National Day holiday and the Mid-Autumn Festival.

On October 1, the national railway transported 16.29 million passengers, China Railway, the national railway operator, said on Monday. On October 2, it is estimated that the national railway will transport 16.40 million passengers, with 11,274 passenger trains in operation, including 906 additional trains.

The Yangtze River Delta region is expected to transfer 3.5 million passenger trips, which is about 28 percent more than the same period in 2019, according to media reports.

The 2023 Golden Week started from September 29 to October 6. The 8-day holiday is the longest public holiday of the year. 

The Ministry of Culture and Tourism estimated there will be 896 million domestic tourists traveling during the Golden Week holiday, an increase of 86 percent compared to last year. Domestic tourism revenue is expected to reach 782.5 billion yuan ($107.2 billion), up by 138 percent on a yearly basis.

The popularity of scenic spots, urban leisure, rural tourism, and visiting relatives and friends has increased significantly, the ministry said.

Localities on Monday started to release travel statistics for the first three days.

Beijing's major scenic spots received 6.825 million tourists during the first three days of the holiday, up by 60.6 percent year-on-year. Tourism revenue reached 4.19 trillion yuan, an increase of 25.2 percent year-on-year.

A netizen posted a photo of the Badaling Great Wall in Beijing, saying that it is not exhausting at all climbing the Great Wall, when you only take two steps in three minutes.

Hangzhou, East China's Zhejiang Province, which is hosting the 19th Asian Games, has welcomed a record number of tourists during the holiday. During the first three days, the city welcomed a total of 4.7 million tourists.

Tickets of many popular scenic spots were sold out, with some sold out even before the holiday started.

Tickets for Mount Taishan in East China's Shandong Province were all sold out until Wednesday. Tickets can be booked 14 days in advance. The current daily limit is 80,000 tourists.

A netizen posted a photo of crowds queuing at the entrance of Mount Taishan at 4:30 in the morning, attempting to avoid huge tourist flows. 

Mount Huangshan in East China's Anhui Province said in an announcement on Sunday that tickets for Monday have been sold out and advised tourists who failed to buy a ticket to avoid the site. Huangshan welcomed 29,753 tourists alone on Sunday.

A number of museums also announced that they have reached their daily limits.

Sichuan Museum in Chengdu, Southwest China's Sichuan Province, said its reservations have reached daily limit of 10,000 visitors until Wednesday.

The Emperor Qinshihuang's Mausoleum Site Museum in Northwest China's Shaanxi Province was also fully booked until Wednesday, with only few tickets left for Thursday and Friday.

A netizen who visited the museum joked: "Even the terracotta warriors would not have room to stand, if they were not put inside the protection window."

China’s largest solid propellant rocket fires 26 satellites into orbit, setting country’s new record

China launched its largest solid propellant rocket Lijian-1 on Wednesday, successfully sending 26 satellites into preset orbit and setting the country's new record for launching multiple satellites in one go. The satellites will mainly provide commercial remote sensing information services.

The Wednesday launch marks the second flight of Lijian-1, indicating the maturity of the solid propellant rocket's technology and the continuous improvement of its reliability, which can further boost the commercialization of China's launch vehicles.

In an exclusive interview with the Global Times, chief engineer assistant on Lijian-1 Shi Xiaoning said he was quite confident about the rocket as its reliability has been verified. But he was still concerned about the separation of satellites from the rocket. 

"This time, there were more satellites to send and we not only needed to ensure that each of them could be successfully separated, but also ensure the accuracy of the satellite's orbit insertion, which was quite challenging," Shi said. "Therefore, we closely monitored data for each satellite separation, but in the end we accurately delivered each satellite to the designated orbit."

Lijian-1 made its maiden flight on July 27, 2022, successfully sending six satellites into their preset orbits. According to its developer, the Chinese Academy of Sciences (CAS), the 2.65-meter-diameter and 30-meter-long new rocket is the largest of its kind in China.

It has achieved breakthroughs in six key technologies and utilized 13 domestic technologies for the first time, enriching China's spectrum of solid carrier rocket launch capabilities and making significant contributions to the technological transformation of China's carrier rocket industry.

Lijian-1 is a four-stage launch vehicle weighing 135 tons at launch with a thrust of 200 tons. It is capable of sending payloads of 1,500 kilograms into 500-kilometer Sun-synchronous orbits (SSO). Prior to that, the capacity of Chinese commercial space rockets in SSO was below 1,000 kilograms.

For the next step, the rocket developer Guangzhou Zhongke Aerospace Exploration Technology Co (CAS Space) will continue to enrich the spectrum of China's solid propellant launch vehicles. In addition to building a sea launch platform for Lijian-1, a new solid rocket with a diameter of 3.5 meters is also under development, the Global Times has learned.

Great tits sing with syntax

Great tits use syntax to compose their tunes.

Japanese great tits (Parus minor) communicate using at least 10 different notes on their own and in combination. Researchers played different calls for Japanese great tits in a forest in Nagano, Japan, to see how the birds responded — an indication of what the call might mean. The birds responded differently to individual notes than they did when played the same note in combination with other notes. And, when researchers reversed the note order, the birds didn’t respond the same way.
By itself, a note means one thing to great tits, but in combination, it means something different, the team argues March 8 in Nature Communications. Similarly, among humans, the order of words in a sentence, its compositional syntax, matters.

Some primates combine calls to convey different messages, but individual notes don’t carry unique meaning in these species. Great tits are the first nonhuman species shown to use compositional syntax, the researchers write.
In this recording, researchers played three types of calls for Japanese great tits: First, a call with three notes — A, B, and C — which signals danger; second, a one-note call (D), which attracts mates; and finally, a combination call, ABC-D, which causes the birds to scan the skies for predators and fly to the source of the sound.
Researchers played an ABC-D call for great tits, and then reversed an ABC-D call. Birds responded differently in each case.

Global obesity rates continue to climb

Despite massive public health campaigns, the rise in worldwide obesity rates continues to hurtle along like a freight train on greased tracks.

In 2014, more than 640 million men and women were obese (measured as a body mass index of 30 or higher). That’s up from 105 million in 1975, researchers estimate in the April 2 Lancet. The researchers analyzed four decades of height and weight data for more than 19 million adults, and then calculated global rates based on population data. On average, people worldwide are gaining about 1.5 kilograms per decade — roughly the weight of a half-gallon of ice cream.
But the road isn’t entirely rocky. During the same time period, average life expectancy also jumped: from less than 59 years to more than 71 years, George Davey Smith points out in a comment accompanying the new study. Smith, an epidemiologist at the University of Bristol in England, boils the data down to a single, seemingly paradoxical sentence: “The world is at once fatter and healthier.”
