China, Greece have vast rooms for cooperation in improving economy, social welfare and mitigating climate change

Editor's note:
China and Greece share a solid foundation of political trust and enjoy robust trade and economic cooperation. This partnership holds substantial potential within the context of the China-CEEC cooperation mechanism and China's Belt and Road Initiative (BRI), which marks its10th anniversary this year. Piraeus Port's transformation led by China COSCO Shipping has been nothing short of extraordinary. In a recent exclusive interview, the Chinese Ambassador to Greece Xiao Junzheng (Xiao) told the Global Times reporter (GT) Yin Yeping how bilateral relations can further deepen and flourish in the coming years.

GT: This year marks the beginning of the second decade of cooperation between China and the Central and Eastern European countries (CEEC). In this context, how could China, Greece, and CEE countries engage in deeper and broader cooperation?

Xiao: Since the initiation of the cooperation mechanism between China and the CEEC, a comprehensive cooperation framework covering more than 20 areas has been established. Many cooperation projects have yielded fruitful results, with bilateral trade doubling over the past decade, and Chinese investment in CEEC increasing sixfold. The China-CEEC cooperation mechanism has become an important platform for the continuous deepening of friendly relations and the ongoing expansion of cooperation between China and the region.
This year marks the beginning of the second decade of cooperation between China and the CEEC. In China's journey toward modernization, Greece can become a significant partner. Likewise, in Greece's efforts to enhance its national competitiveness, China could be a crucial partner, providing assistance and support.
China and Greece enjoy a high level of political mutual trust, a strong foundation for cooperation, and significant potential for the future within the framework of the China-CEEC mechanism. In the future, cooperation can focus on the following aspects:
Firstly, promote mutually beneficial and practical cooperation. The Greek government has prioritized digital transformation and the development of a green economy. Both China and Greece can further align their growth strategies, while expand cooperation in green economy, digital economy, technology innovation, and the service industry.
Secondly, enhance connectivity. China COSCO Shipping's investment project at Piraeus Port and the China-Europe Land-Sea Express Line originating from Piraeus Port have evolved into crucial links between land and sea, effectively connecting Europe and Asia.
In the future, China and Greece can strengthen their commitment to the comprehensive development plan for Piraeus Port, enhance cooperation in trade, make new contributions to stability of the China-Europe industrial and supply chains, promoting economic integration in the Balkans, and advancing the EU integration.
Thirdly, accelerate cultural and tourism cooperation. China supports Greece in hosting the 6th China-CEEC High-level Conference on Tourism Cooperation. China is willing to work with Greece to do a good job in cooperation regarding China-Greece Year of Culture and Tourism, continue to implement the Joint Action Program 2022-2024, build tourism brands, and initiate a broader spectrum of diverse cultural and tourism cooperation.

GT: How do you view the significance of Chinese companies' achievements in Piraeus Port for promoting economic recovery of Greece and the development of China's international maritime industry? What insights can the success in Piraeus offer for future cooperation?

Xiao: Since China COSCO Shipping Group took over the operations of Piraeus Port, they have managed it actively and prudently, making efforts to expand its market presence. This century-old port has experienced a remarkable revival and achieved significant growth, propelling the rapid advancement of local logistics and industrial chains.
Currently, the Piraeus subsidiary of COSCO Shipping has invested over 1 billion euros in port construction. The Piraeus Port has seen a significant rise in container throughput ranking, climbing from 93rd place in 2010 to 29th place in 2021, establishing itself as a leading Mediterranean port. This development has directly created over 3,000 jobs for local community. In total, the efforts have contributed over 1.4 billion euros to local community.
Piraeus Port is the closest European port to the Suez Canal, making it a crucial gateway for Asian goods, including those from China, to enter Europe. Piraeus' development has attracted cargo from multiple countries as a transshipment hub to Europe, significantly enhancing international trade efficiency and reducing shipping costs.
The success of the Piraeus project serves as a vivid example of the BRI and stands as a significant achievement in the cooperation between China and Greece. As long as both China and Greece remain committed to their shared goals, uphold the principles of consultation, joint construction, and shared benefits, and continue to foster a spirit of cooperation and mutual prosperity, by aligning their national development strategies, it is believed that practical cooperation between China and Greece will continue to yield even more fruitful results in the future.
GT: There are voices trying to undermine the mutually beneficial cooperation between China and Greece, the narratives like "China's investment in global ports is a threat." How do you view these voices?

Xiao: China's promotion of the joint construction of the BRI is not driven by geopolitical maneuvering, nor does it pursue self-interest for hegemonic purposes. And, China does not seek to create disruptive alliances. Over the past decade since China introduced the initiative, it has consistently adhered to the principles of mutual consultation, cooperation, and shared benefits. As a result, the Belt and Road has evolved into a widely embraced international public good and a platform for international cooperation. There are some voices alleging that China's investment in Piraeus Port has "non-commercial purposes," which are entirely baseless.
The facts demonstrate that China's cooperation with relevant countries, including Greece, in port development is aimed at promoting economic and trade cooperation between nations. This cooperation contributes to local economic development, infrastructure improvement, and job creation. It is based on mutual benefit and results in win-win outcomes for all parties involved.
In my previous introduction, I highlighted the outstanding achievements that COSCO Shipping Group has secured in operating Piraeus Port. It has transformed Piraeus into a port of win-win cooperation, green development, economic growth and more. The international community has widely recognized these accomplishments, and high-ranking Greek officials, including the President and Prime Minister, have praised the mutually beneficial nature of this project.
In 2022, Piraeus Port also received awards such as the "Outstanding Contribution to Tourism Industry" award from the Greek Ministry of Tourism and the "Diamonds of the Greek Economy" award from Hellenic Shipping News. These accolades further illustrate the widespread recognition and approval of the Piraeus Port project by Greek society.
China's practical cooperation with countries around the world in infrastructure development, including port construction, strictly adheres to the principles of consultation, joint construction, and shared benefits. It aims to create more opportunities for mutual development. This cooperation is conducted transparently and openly, without posing any security threats to any country.

GT: With the optimization of anti-pandemic policies, Greece is expected to see more Chinese tourists. What do you think are the opportunities for cooperation between China and Greece in tourism and cultural exchanges?

Xiao: China and Greece are both ancient civilizations and significant global tourist destinations. People to people exchanges are essential components of practical cooperation. The tourism industry is one of the pillars of the Greek economy, contributing some 20 percent to Greece's GDP. China, with the world's largest middle-income population, has seen rapid development in the tourism market.
In the post-pandemic era, both China and Greece will continue to actively implement the 2022-2024 Joint Action Program, focusing on enhancing cooperation in tourism.
Both sides will make full use of existing tourism cooperation platforms and utilize platforms like the China International Travel Mart to promote bilateral tourism cooperation. Efforts will also be made to enhance visa processing efficiency, and increase direct flights.
I believe that the orderly recovery of China's outbound tourism will enhance the friendship between Chinese and Greek people, strengthen the ties of cultural exchange between China and Greece, and better leverage the tourism industry's significant role in promoting economic development and deepening the friendship between the two countries.

GT: The New Democracy party, led by Greek Prime Minister Kyriakos Mitsotakis, recently won a second four-year term. What are your expectations for bilateral cooperation in the coming months?

Xiao: The ancient Greek philosopher Aristotle once said, friendship is a single soul dwelling in two bodies. China and Greece are comprehensive strategic partners with a history of friendly exchanges dating back thousands of years. In the 51 years since establishing diplomatic relations, both countries have navigated the changing international landscape. Both sides have demonstrated mutual understanding and support on issues of core interests and major concerns. The two countries have become an exemplary model of peaceful coexistence and win-win cooperation between nations of different scales, systems, national conditions, and civilizations.

Following the re-election of the New Democracy Party government, they have continued to support the co-development of the BRI and cooperation between China and Central and Eastern European countries. They are willing to work hand in hand with China to deepen mutually beneficial cooperation.

I believe that in the future, under the guidance of the high-quality construction of the BRI, both sides will promote the realization of China's modernization model and Greece's enhancement of its national competitiveness. Together, both sides will nurture new areas of cooperation such as green development and the digital economy, bringing greater prosperity to the people of both countries.

GT: How do you evaluate the cooperation achievements between the two countries under BRI? And, in which areas could the two countries ramp up their cooperation?

Xiao: China and Greece, despite being geographically distant, have a history of communication dating back over 2,000 years through the ancient Silk Road that spanned east and west. Today, in the midst of deepening globalization, the cooperation in building the BRI is once again connecting the two great civilizations.
With the joint efforts of China and Greece, their mutually beneficial cooperation has yielded fruitful results. This has not only enriched the content of the comprehensive strategic partnership between China and Greece but also has brought tangible benefits to the people of both countries.
Since China COSCO Shipping took over the management of the Piraeus Port, the port has experienced a remarkable transformation. The container throughput has grown from 880,000 TEUs in 2010 to over 5 million TEUs today, making it a leading port in the Mediterranean.
The China-Europe Land-Sea Express Line, from its inception, has become the third trade corridor between China and Europe, in addition to traditional maritime routes and China-Europe freight trains.
China's State Grid Corporation's investment in the Greek national electricity grid project, and State Power Investment Corporation's acquisition of the Kafireas wind power project have alsoy generated significant economic and social benefits.
In the journey to develop green and digital economies and to build new national competitiveness in Greece, both China and Greece can strengthen their partnership through high-quality cooperation in the BRI. We can consolidate and deepen existing cooperation projects, advance connectivity cooperation represented by Piraeus Port and the China-Europe Land-Sea Express Line.

GT: In your opinion, what areas of deep cooperation could China and Greece engage to address climate change and promote green, low-carbon transformation?

Xiao: This summer, Greece experienced extreme high temperatures and wildfires, while many regions in China faced high temperatures and extreme rainfall. Both China and Greece are victims of global climate change and share common aspirations and motivations in addressing climate change.
China adheres to the concept of new development and actively promotes green and low-carbon development, fulfilling international commitments in addressing climate change. In recent years, Greece has also been proactive in addressing climate change issues, enacting clear emission reduction legislation, advancing energy structural adjustments, and vigorously developing a green economy.
The concept of green development is increasingly being reflected in the cooperation projects between the two sides.
Chinese new-energy vehicles have entered the Greek market this year. China and Greece have strengthened their strategic alignment in technology development under the framework of the China-Greece Joint Committee on Science and Technology Cooperation and the Belt and Road Science, Technology and Innovation Cooperation Action Plan.
In the Memorandum of Understanding on China-Greece Scientific and Technological Cooperation signed by the two countries' science and technology departments last year, addressing climate change emerged as a key area of collaboration, with a focus on forest management, challenges related to water resource biodiversity, and climate adaptation policies. Both countries have already established a solid cooperation foundation in green and low-carbon transformation fields such as biomanufacturing and solar energy.
China and Greece have vast rooms for cooperation related to mitigating global climate change by promoting green growth.

China's surged consumption on first day of Golden Week holidays

The vast potential of China's domestic consumer market was on full display on Friday, the first day of Mid-Autumn Festival and National Day holidays, as catering and the box office embraced significant increase in business activity. 

Starting from starting from September 29 to October 6, the 8-day-holiday is the longest public holiday of the year. Analysts expect to see a surge in domestic consumption. 

Multiple entertainment and consumption areas in Beijing welcomed crowds of visitors on Friday as 60 major business districts across the capital city saw a total of 6.89 million people visit, an increase of 11.9 percent year-on-year, according to the Beijing Municipal Commerce Bureau on Saturday. 

The bureau also reported total daily sales of nearly 100 shopping malls, supermarket, online and offline stores, restaurants reached 1.39 billion yuan ($190.54 billion), up 40.4 percent year-on-year. 

According to data from Chinese food delivery platform Meituan and Dazhongdianping, a Chinese version of Yelp, as of Friday noon, the volume of dine-in order increased by 110 percent over the first day of 2022 National Day holidays.

China’s total box office (pre-sale included) of new films during the 2023 Golden Week holidays crossed 1 billion yuan as of 21:18 on Saturday, according to ticketing platform Dengta. The top three are all domestic films - Under the LightEx-files 4: Marriage Plan and Korean War-themed epic The Volunteers: To the War. 

Chinese government to ramp up proportion of EVs in official fleets, a boost for sector’s growth

Chinese officials have vowed to ramp up proportion of electric vehicles (EVs) in official car fleets, as part of the government's efforts to promote green car sales and EV sector growth. 

The National Government Offices Administration (NGOA) said in an online post last Saturday that it held a meeting on promoting EVs and management of official car fleets from September 26 to 27 in the Xiong'an New Area in North China's Hebei Province. Local officials from 31 provincial-level regions attended the meeting. 

The meeting called on all levels of departments in charge of official car fleets to fully implement various policies on promoting EVs, strengthen cooperation with industry regulators, improve supplementary systems, and increase the use of NEVs, according to the post.  

The meeting noted that official fleets are important assets crucial for ensuring efficiency of Party and government departments and public institutions. Strengthening management of official fleets and promoting government departments to use more EVs is important work to consolidate the results of institutional reform.

In 2015, China released a guideline on reforming the country's official fleet system at all central government departments. To further strengthen the management of official fleets, the NGOA released interim regulations on management of official car fleets on September 12, 2023.

The regulations placed a priority on facilitating the use of EVs as a proportion of government car fleets. Central institutions are required to make annual plans on renewal of official vehicles, including the number NEVs, and ensure the proportion of NEVs meets requirement. 

As the leading NEV producer in the world, China has issued over 70 administrative measures to encourage the nascent industry to grow during recent years, which include carrying out innovative projects and forming manufacturing centers for batteries, according to Xinhua.

According to data from the China Association of Automobile Manufacturers, China's new-energy vehicle production and consumption rose by 36.9 percent and 39.2 percent year-on-year, respectively, to 5.43 million and 5.37 million in the first eight months of 2023.

Chinese researchers find way to manufacture highly flexible, paper-thin solar cells

Chinese researchers have developed a special technology to tailor the edges of textured crystalline silicon (c-Si) solar cells, based on which the solar cells can be bent and folded like thin paper, allowing for broader application and use.

The breakthrough was achieved by Chinese researchers at the Shanghai Institute of Microsystem and Information Technology (SIMIT) under the Chinese Academy of Sciences. The results have been featured on the cover of the May 24 edition of Nature journal.

The c-Si solar cells fabricated with the new technology can be 60 millimeters thin with a bending radius of about 8 millimeters.
According to the Technology Daily, c-Si solar cells are type of solar cell seeing fast development at the moment. They have advantages including long service life and high conversion efficiency, making them a leading product in the photovoltaic market.

Such c-Si solar cells have a market share of more than 95 percent, according to Di Zengfeng, deputy head of the SIMIT, who is one of the authors of the research paper.

Although c-Si solar cells were developed nearly 70 years ago, their use is still limited, the paper explained. Currently, the c-Si solar cells are mainly used in distributed photovoltaic power stations and ground photovoltaic power stations. Hopefully, such solar cells can be used in construction, backpacks, tents, automobiles, sailing boats and even planes.

They can also be used to generate clean energy for houses and a variety of portable electronic and communication devices as well as for transportation, according to the researchers.
Liu Zhengxin, a research fellow with the SIMIT, and another author of the paper, said that the study verified the feasibility of mass production, providing a technical route for the development of lightweight and flexible c-Si solar cells.

At the same time, the large-area flexible photovoltaic modules developed by the research team have been successfully applied in the fields of near-space vehicles, building photovoltaic integration and vehicle-mounted photovoltaic systems, Liu said.

Six grave robbers sentenced 10-20 months following three poisoned to death in north China's Inner Mongolia Autonomous Region

A gang of grave robbers in north China's Inner Mongolia Autonomous Region have been sentenced to prison terms ranging from 10 months to 20 months after three people died of carbon monoxide poisoning, a local court ruled on August 11.

On the eve of the Dragon Boat Festival in 2022, Chen and five others gathered together and brought tools such as shovels and pickaxes to illegally excavate ancient tombs on a mountainside in Aohan Banner in Chifeng in north China's Inner Mongolia Autonomous Region. They stopped two days later due to rain.

Chen and others were unwilling to give up. Several days later, they gathered again adding several members to their group. However, they harbored ulterior motives and were unwilling to pay for the tools needed, which led to an internal conflict, resulting in the disbandment, according to an official from the People's Court of Aohan Banner.

More than a month later, Chen still couldn't accept what had happened and organized a group of eight people to dig up the cave at night. They bought gasoline pumping equipment to drain the accumulated water from the cave to keep digging.

However, the gasoline pumping equipment generated a large amount of carbon monoxide gas inside the cave, resulting in the poisoning and death of three people. According to the local court official, the incident of robbing grave was then exposed, and the other five people voluntarily turned themselves over to the police.

According to the local court, the defendants have violated the national cultural relics management system by secretly excavating ancient tombs with historical and scientific value. Their actions constituted the crime of grave robbery and are considered joint offenders.

The six defendants were sentenced to imprisonment ranging from 10 months to 20 months, with fines also being imposed on each member of the group.

The Aohan Banner has a rich historical and cultural heritage. According to the local court, over 4,000 ancient cultural sites and tombs from different periods have been discovered within the Aohan Banner, making it the leader in China. In recent years, the local court has been handling criminal acts related to the protection of cultural relics and cultural heritage in accordance with the law, as stated by local court officials.

Foxconn founder Terry Gou announces to run for Taiwan regional leader, ‘making anti-DPP camp more divided’

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

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

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

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

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

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

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

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

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

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

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

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

Historian puts new spin on scientific revolution

When Columbus discovered America, European culture hadn’t yet grasped the concept of discovery. Various languages had verbs that could be translated as discover, but only in the sense of discovering things like a worm under a rock. Scholars operated within a worldview that all knowledge had been articulated by the ancients, such as Ptolemy, the astronomer who compiled the mathematical details of the Earth-centered universe. As it happened, Ptolemy was also the greatest of ancient geographers. So when Columbus showed that Ptolemy’s grasp on geography was flawed, it opened the way for Copernicus to challenge Ptolemy on his picture of the cosmos as well. Deep thinkers who were paying attention then realized that nature possessed secrets for humankind to “discover.”
“The existence of the idea of discovery is a necessary precondition for science,” writes historian David Wootton. “The discovery of America in 1492 created a new enterprise that intellectuals could engage in: the discovery of new knowledge.”

Appreciating the concept of discovery was not enough to instigate the invention of science. The arrival of the printing press in the mid-15th century was also especially essential. It standardized and magnified the ability of scholars to disseminate knowledge, enabling the growth of communities, cooperation and competition. Late medieval artists’ development of geometrical principles underlying perspective in paintings also provided important mathematical insights. Other key concepts (like discovery) required labeling and clarifying, among them the idea of “evidence.”

And modern science’s birth required a trigger, a good candidate being the supernova observed by Tycho Brahe in 1572. Suddenly, the heavens became changeable, contradicting the Aristotelian dogma of eternal changeless perfection in the sky. Tycho’s exploding star did not cause the scientific revolution, Wootton avers, but it did announce the revolution’s beginning.

In The Invention of Science, Wootton incorporates these insights into an idiosyncratic but deeply thoughtful account of the rise of science, disagreeing frequently with mainstream science historians and philosophers. He especially scorns the relativists who contend that different scientific views are all mere social constructions such that no one is better than any other. Wootton agrees that approaches to science may be socially influenced in their construction, but nevertheless the real world constrains the success of any given approach.

Wootton’s book offers a fresh approach to the history of science with details not usually encountered in the standard accounts. It might not be the last or even best word in understanding modern science’s origins or practice, but it certainly has identified aspects that, if ignored, would leave an inadequate picture, lacking important perspective.

Environment still tied to MS risk

Multiple sclerosis clue significant — A possible link between environment and multiple sclerosis (MS) could be a valuable tool in searching for the cause and cure of the disease…. Cases of MS seem to appear in clusters, and there is apparently some as yet unknown environmental factor that is distributed in the same way, reported Dr. John F. Kurtzke.… The highest frequency of MS is found in northern United States, southern Canada and northern Europe, where there are 30 to 60 cases per 100,000 population. — Science News, April 16, 1966

Update
Researchers still aren’t sure what causes MS, a debilitating disease in which the body’s immune system attacks the insulation around nerve cell fibers. But research suggests that people who grow up farther from the equator, with reduced sun exposure, may have increased disease risk. The human body produces vitamin D in response to sunlight, and studies show that lower levels of vitamin D lead to higher MS risk (SN Online: 9/10/15). But other factors, including genetics and infections, may also play a role in disease development. Today, an estimated 90 MS cases occur for every 100,000 people in the United States.

There’s far more to the galaxy than meets the eye

The pale arch of light from the plane of our galaxy can be a humbling sight on a clear, dark night. But it’s just a sliver of all the treasures lurking in the Milky Way. Dense clouds of interstellar dust block visible light from remote regions of the galaxy but allow longer wavelengths to pass through. In February, astronomers completed a new map of our galaxy as seen in submillimeter light, which is shorter than radio waves but longer than infrared waves.

Submillimeter light can penetrate dust clouds, revealing details at the center of the galaxy and in stellar nurseries not visible at other wavelengths. The map was produced by ATLASGAL, a project using the APEX telescope in northern Chile to map part of the Milky Way. The project charted one-third of the band of galactic light that encircles our solar system; the images below show a narrow slice toward the constellation Sagittarius.
Combined with images from the Spitzer and Planck satellites, the ATLASGAL map (top row) creates a detailed atlas of some of the cold structures in our galaxy. Dust clouds in places like the Trifid and Lagoon nebulas (circled, left), both a few thousand light-years away, glow faintly, as do filaments of detritus in the center of the galaxy (circled, right), 28,000 light-years from Earth. At near-infrared wave-lengths (center row), these regions nearly vanish behind obscuring curtains of dust. The galactic center remains hidden in visible light (bottom row) as well, though hot stars in Trifid and Lagoon radiate pools of hydrogen gas, making them glow.

Words’ meanings mapped in the brain

In the brain, language pops up everywhere.

All across the wrinkly expanse of the brain’s outer layer, a constellation of different regions handle the meaning of language, scientists report online April 27 in Nature.

One region that responds to “family,” “home” and “mother,” for example, rests in a tiny chunk of tissue on the right side of the brain, above and behind the ear. That region and others were revealed by an intricate new map that charts the location of hundreds of areas that respond to words with related meanings.
Such a detailed map hints that humans comprehend language in a way that’s much more complicated — and involves many more brain areas — than scientists previously thought, says Stanford University neuroscientist Russell Poldrack, who was not involved in the work.

In fact, he says, “these data suggest we need to rethink how the brain organizes meaning.”

Scientists knew that different concepts roused action in different parts of the brain, says study coauthor Jack Gallant, a computational neuroscientist at the University of California, Berkeley. But people generally thought that big hunks of the brain each dealt with different concepts separately: one region for concepts related to vision, for example, another for concepts related to emotion. And conventional wisdom said the left hemisphere was most important.

Previous studies, though, tested just single words or sentences, and made only rough estimates of where meaning showed up in the brain, Gallant says. That’s like looking at the world’s countries in Google maps, instead of zooming in to the street view.

So he and colleagues mapped the activity of some 60,000 to 80,000 pea-sized regions across the brain’s outer layer, or cerebral cortex, as people lay in a functional MRI machine and listened to stories from The Moth Radio Hour. (The program features people telling personal, narrative tales to a live audience.)
“People actually love this experiment,” Gallant says.

It stands out from others because the authors use “real life, complicated stories,” says Princeton University neuroscientist Uri Hasson. “That’s really meaningful to see how the brain operates.”

Gallant’s team used a computer program to decipher the meaning of every 1- to 2-second snippet of the stories and then cataloged where 985 concepts showed up in the brain. Meanings conveyed by different words didn’t just engage the left hemisphere, the team found, but instead switched on groups of nerve cells spread broadly across the brain’s surface. After mapping where meaning, or semantic content, was represented in the brain, the researchers figured out where individual words might show up. Often, the same word appeared in different locations. For instance, the word “top” turned up in a spot with clothing words, as well as in an area related to numbers and measurements.

The brain maps of the seven participants in the study looked remarkably similar, Gallant says. That could be due to common life experiences: All seven were raised and educated in Western societies. With so few people, the researchers can’t pick out any gender differences, he says, but ideally he’d like to repeat the experiment with 50 or 100 people.

For now, Gallant hopes the map can serve as a resource for other researchers. One day, the work could potentially help those with ALS or locked-in syndrome communicate ­— by decoding the words in a person’s thoughts. But that’s just one piece of the puzzle, Gallant says. Researchers would also need to devise a method for measuring brain activity that’s portable, unlike MRI machines.
