Editor's Note:

Kazakhstan marks the lynchpin for the China-proposed Belt and Road Initiative (BRI), not only because geographically it acts as a key point along the BRI, and has fostered deep connections and conducted meaningful cooperation with China covering almost all sectors under the BRI framework, but also because Kazakhstan was where the initiative was first proposed 10 years ago.

As the BRI is set to celebrate its 10th birthday this month, China-Kazakhstan cooperation can offer a paragon of how the initiative has deepened both countries' connectivity, boosted trade, as well as benefited both peoples and brought the two countries closer. Moreover, it also offers examples of how the BRI's win-win cooperation has stood against unilateralism; how the initiative has broken geographic isolation and brought countries closer; in addition to enabling people from different countries to better understand each other.

As the 10th anniversary of BRI approaches, Global Times reporters have visited a number of countries and regions across Southeast Asia, Central Asia, Africa, Central and Eastern Europe, as well as the South Pacific, where they witnessed first-hand the success of the BRI and how it has improved life in those countries and regions. This is the third installment, which focuses on how the BRI has been helping to usher in a new era of development in Eurasia over the past decade.

Revisiting the starting point

In mid-August, Nazarbayev University in Astana, capital of Kazakhstan, has already begun to welcome new faces. When Global Times reporters visited the campus on a cool and clear summer afternoon, a number of student societies and interest clubs attached to the university were recruiting new members, attracting hundreds of freshmen to participate. Everywhere, sounds of music and laughter could be heard, signs in English, Kazakh and Russian could be seen, and an energetic and youthful atmosphere could be felt.

Vibrant and highly internationalized - no other words could possibly be more accurate in describing Nazarbayev University. And they are also true for the BRI first proposed by Chinese President Xi Jinping at this very location 10 years ago.

The young Nazarbayev University, founded only in 2010, is now widely considered to be the starting point for the revitalization of the millennia-old Silk Road under the BRI. The concept "Silk Road Economic Belt," part of the BRI, was officially proposed during President Xi's visit to Kazakhstan in 2013. In a speech in Nazarbayev University's Senate Hall on September 7, 2013, Xi recalled the 2,000-plus-year history of exchanges between China and Central Asia along the ancient Silk Road and proposed joining hands to build a Silk Road Economic Belt with an innovative cooperation model and making it a grand cause benefiting people in countries along the route. 

Ten years later, the Senate Hall, filled with dark wood furniture that are mostly the same as in 2013, remains in good condition. This is because the room is now mostly used only for events like ceremonies and officials' visits, according to a staff member from the university. 

Usually, there are more than 200 seats in this conference hall. Around 100 more seats were added before President Xi's epoch-making speech in 2013 due to the high demand from students and faculty members to participate in the event. A live broadcast was even arranged for those who couldn't enter the scene. Xi's remarks were greeted with warm applause from the audience, recalled the staff member.

Gulnar Shaimergenova, Director of China Studies Center, Kazakhstan was working at the Nazarbayev University at the time and directly participated in the event when President Xi first proposed the Silk Road Economic Belt there. "I am sure that the Belt and Road Initiative, which represents the reconstruction of the Great Silk Road of the 21st century, became the most remarkable event of this century. It reflects the rise and grandeur of modern Asia," Shaimergenova told the Global Times.

Shaimergenova said that the implementation of BRI is strategically beneficial for Kazakhstan. "The transformation of China into a key trade partner of the EU has been made possible to some extent thanks to the stable operation of China-Europe rail routes - up to 80 percent of which pass through Kazakhstan. Further development of China-Europe trade relations implemented through land corridors is economically beneficial for Kazakhstan."

The smooth promotion of BRI cooperation between China and Kazakhstan was also advanced by the strategic guidance of the leaders from both countries. 

President Xi has visited Kazakhstan four times in September 2013, May 2015, June 2017; and September 2022, the last of which marked his first trip abroad since emergence of the COVID-19 pandemic. Kazakh President Kassym-Jomart Tokayev paid a state visit to China in September 2019, attended the Beijing Winter Olympics in February 2022, and also attended the China-Central Asia Summit in May 2023.

Over recent years, China's relationship with Kazakhstan has continued to strengthen. In 2019, China and Kazakhstan decided to develop a permanent comprehensive strategic partnership. 

I am very pleased that Kazakhstan became the first country to support the idea of the BRI, and actively participates in its development, Aidar Amrebayev, Director of the Political Studies Center in Almaty, Kazakhstan told the Global Times. 

After 10 years since the announcement of the initiative, many projects have been implemented in Kazakhstan, benefiting our country and the entire Central Asian region. These projects involve expanding transport and logistics capabilities, modernizing industrial and agricultural infrastructure, enhancing mutual understanding among our peoples, and fostering active inter-country interactions at the political level, Amrebayev opined. 

"I am happy to say that 10 years later, all my expectations [about the BRI] have materialized," former Secretary-General of the Shanghai Cooperation Organisation (SCO) and Chairman of the Board of the Foreign Policy Research Institute under Kazakhstan Foreign Affairs Ministry Bolat Nurgaliyev told the Global Times. The development of the BRI, going through stages, has gone hand in hand with the concept of a community with a shared future for mankind, he added.

The decade-old BRI cooperation proves that we have to show inclusiveness by involving countries in constructive cooperation instead of confrontation, division, and ideological divergence in the immediate political considerations, Nurgaliyev added.

Robust economic cooperation, warm people-to-people exchanges

Astana is one of the youngest capitals in the world. Yet, it is also one of the most modernized and fast-growing cities in Central Asia. From the Chinese businesspeople coming out from the striking Chinese-style building known as the Beijing Palace in the city center to the city's first light rail system under construction with the help of a Chinese company, they mark the changes that China and the BRI have brought to Kazakhstan's capital.

In Almaty, the former capital and largest city in Kazakhstan, advertisements for Chinese electronic devices, vehicles and even sportswear are easy to find. Locals told the Global Times that from China-made smartphones to electric vehicles, Chinese products are popular among Kazaks. At the same time, Kazakhstan was the second country to open a national pavilion on the Alibaba e-commerce platform and more than 200 Kazakh enterprises are running business on the Chinese platform.

According to the General Administration of Customs of China, the total volume of trade in goods between China and Kazakhstan stood at $31.17 billion in 2022, up 23.6 percent from the previous year. In 2022, the trade volume between China and Central Asian countries registered a record of over $70 billion.

The story of Yuan Zhaohui, a Chinese businessman is a vivid example of the robust economic cooperation between two countries. Yuan has been operating cross-border trade with his partners from Kazakhstan for eight years. He started his business from scratch as the first company in the Xi'an International Trade and Logistics Park to use the Chang'an train to ship cross-border e-commerce goods.

At present, about 80 percent of his company's business is linked with Kazakhstan, other Central Asian countries and Russia through the train service. The stable operation of China Railway Express has greatly reduced freight costs for his business.

Taking the road from Xi'an to Almaty as an example, the cost of freight for a container transported by the Chang'an train is about 50,000 to 60,000 yuan ($7,130 to $8,560), which is half the price of traditional land cross-border transport, according to Yuan. The simplified and easier custom declaration for cross-border e-commerce companies has also served to accelerate the growth of his business.

Agriculture is another key area of China-Kazakhstan cooperation that is vigorously developing under the BRI framework. Located in the North Kazakhstan Region, more than 300 kilometers north of Astana, is the Kazakhstan processing park of the Aiju Grain and Oil Industrial Group headquartered in Xi'an, Northwest China's Shaanxi Province. The company is one of the first Chinese enterprises that engage in agricultural investment and cooperation in Kazakhstan under the auspices of the BRI.

Kazakhstani local Yerkenbek Sidick has been working in Aiju's agro-processing and logistics park since 2017. He has witnessed how his company has transformed from a few Soviet-era grain silos into a comprehensive base with large-scale grain storage and distribution capacity.

The Aiju processing park has built a modern oil processing plant with a maximum annual output of 300,000 tons of processed oil crops and a depot that can store 50,000 tons of grains. It has dispatched more than 200 freight trains to deliver 350,000 tons of high-quality raw materials, such as wheat and rapeseed, from the North Kazakhstan Region to China through the Alashankou port.

More than 10 years ago, very few Chinese companies were active in Kazakhstan, and even fewer showed interest in taking roots in the country and making long-term investments, Sidick told the Global Times. With the implementation of the BRI, more and more Chinese companies have begun to pay attention to Kazakhstan, boosting the cooperation and development of the two countries in various fields, including agriculture.

From trade and investment to capacity cooperation, from connectivity to emerging industries, from joint efforts in fighting against the pandemic to cultural exchanges, the all-round mutually beneficial cooperation between China and Kazakhstan has demonstrated strong vitality and resilience, and the foundation of people-to-people friendship is becoming increasingly concrete, Chinese Ambassador to Kazakhstan Zhang Xiao told the Global Times in an exclusive interview. 

Specifically, he gave an example of a large number of exemplary projects built by both sides, such as the Shymkent Oil Refinery, the photovoltaic power plant in Almaty, the Orda glass plant in Kazakhstan's Kyzylorda Region, saying that those projects greatly improved Kazakhstan's industrialization level and benefited local residents.

Aside from economic cooperation, China and Kazakhstan are also embracing close people-to-people exchanges. Those two countries are cooperating in areas such as publishing books, jointly making films, doing archaeological research together and establishing universities… Such interaction between the two countries has laid the foundation for friendly exchange between two peoples. 

Famous Kazakh director and producer Akan Satayev is planning to co-produce a film with China. He told the Global Times that China and Kazakhstan are both countries along the Silk Road, which renders them to share a common history and culture. Satayev said he is very interested in Chinese culture, and he hopes to find more common points in the history and culture of China and Kazakhstan and make films and television works based on such findings. "This will definitely bring us closer together," said Satayev.

"The BRI has helped China 'go global' and broaden the Chinese people's horizon, while enhancing Central Asia's understanding of China," said He Cheng, Chief Representative of the Kazakhstan International Integration Foundation. As the understanding of people in Central Asia and China on each other deepens, people now become more open-minded and see the opportunity and potential of bilateral and multilateral cooperation under the BRI framework, he noted.

In He's opinion, the BRI is no longer a link of communication, but a model of cooperation between countries in a honeycomb structure. "With the deepening and widening of cooperation, we are ultimately moving toward the establishment of a community," he told the Global Times.

Brighter future

In 2014, a $9 billion infrastructure project known as "Nurly Zhol," translated as "Bright Path," was announced by Kazakhstan's government. Since then, the integration between the BRI and Nurly Zhol has been constantly discussed in Kazakhstan's strategic and political circles.

"The two programs should be interconnected. They should be coordinated so that what has already been started as projects within the Nurly Zhol should be somewhat supplemented. This will be a better use of the capital of the investment," former SCO Secretary-General Nurgaliyev commented.

In many senses, the development road the BRI has provided can also be described as "bright." Ten years on, this ambitious initiative has benefited Central Asia through close cooperation, including improving infrastructure, providing jobs and boosting bilateral trade. It is now a path that is even brighter than a decade ago and has the ability to lead the region and the world to a brighter future.

Nurgaliyev believes that the BRI will continue to develop. "The circle of participation in the BRI is already so wide. We have now 193 states in the United Nations system, and 152 are BRI participants," he said. "So what better argument can prove that the BRI is beneficial for everybody who participates in the implementation?" the diplomat noted.

On September 7, 2023, the 10-year anniversary day of the proposal of BRI, a seminar was held by think tanks from China and Kazakhstan at Nazarbayev University. 

As a participator of the seminar, Shaimergenova said "I am sure that the Belt and Road Initiative, which represents the reconstruction of the Great Silk Road of the 21st century, became the most remarkable event of this century. It reflects the rise and grandeur of modern Asia."

With the support of China, Central Asia now is beginning to realize economic revival as the region becomes a contributor to its own development. By embedding in the East-West transport communications, the problem of continental isolation is being eliminated, and strong prerequisites for intra-regional cooperation are being created, said Shaimergenova.

Cooperation along the BRI has a strong impact on the prosperity and progressive development of several billion people around the world. I am sure that the Initiative will be a good basis for building the Community of the common destiny of mankind, she noted.

The further flourishing of the BRI is a general wish from not only scholars and diplomats from Kazakhstan, but also ordinary people like Sidick from Aiju's processing park in the Central Asian country.

"After our company's seven-year journey in Kazakhstan, now we are expecting a harvest," Sidick told the Global Times. 

"I hope that the road of BRI will become wider and wider to attract more Chinese companies to develop and invest in Kazakhstan and drive the two countries' economic development and people-to-people exchanges. I am looking forward to finding my own position and creating more value for my company and the BRI," said the Kazakh young man with a big smile on his face.

At the recent G20 summit, the India-Middle East-Europe Corridor (IMEC) backed by the US, Europe and India under the Partnership for Global Infrastructure Investment was announced. This corridor aims to connect Europe, the Middle East and India with rail and shipping routes.

With Biden calling it a "really big deal" and National Security Advisor Jake Sullivan describing the project as "transformative," the project has already been described as one that counters China's Belt and Road Initiative (BRI), which has been signed up to by the majority of the world.

However, the working group tasked with drawing up a fuller plan, over the next sixty days, will have to confront some harsh economic realities relating to funding, material capabilities and the ideological outlook of the main countries involved.

When it comes to funding, let's not forget that the Build Back Better Plan undertaken by the G7 in 2021 to counter the BRI was consigned to the dustbin of history the same year it was announced.

The $1.7 trillion package (less than two years of US defense spending) was considered too costly.

Railway linking India, the Middle East and Europe would be the center piece of the IMEC. When it comes to infrastructure, the US and India do not set good examples for others to follow, yet they expect to compete with China which has first-rate infrastructure. Rather than build something abroad, based on hegemonic competition against China, it would be better for the US and India to demonstrate they can solve the basic democratic infrastructural needs of their citizens first.

Even if internal infrastructural issues and financing can somehow be overcome, the ideological attitude of maintaining economic hegemony that the West holds toward the Global South acts as a barrier to the IMEC. Only with gunship diplomacy could the US force states to buy exclusively from expensive Western companies. Even then, many components will be sourced from China.

At any rate, we are in a multi-polar world now. The Saudi-Iran rapprochement, the enlargement of BRICS, and the good relations in the region toward Russia and China show that the Middle East refuses to take sides and will trade with all. Another Iraqi-style invasion in the region to maintain US-led economic predominance would be foolhardy, as such, the West must be competitive in the market.

Currently, Saudi Arabia is choosing China when it comes to rail construction - though this too is an international effort that pulls in Western companies. The China Railway 18th Bureau Group has already completed the 450km-long Mecca-Medina High-speed Railway and is working on the Medina Tunnel Project along with the Saudi Rua Al Madinah Holding Company, Canada's WSP and US-based Parsons. The linking of Saudi's eastern and western seaboard, while led by China, is also a joint international project. This further highlights the lunacy and impracticality of fencing off the world economy.

One of the major forces driving US hegemonic attempts is its capitalist system which seeks immediate profits. This motivation has led to the decay of US infrastructure and a lack of long-term railway investment; a similar "democratic" system sees India's infrastructure in shambles too. Furthermore, much of the Global South remains in tatters after being harvested by the US military-industrial complex, which seeks quick profits from war and sees development as a threat to its economic hegemony.

In contrast, The BRI is premised on long-term social economic planning. Some projects will not be profitable for decades - many will provide immense social-economic benefits but no profit extraction for private capital. China's socialist system subordinates capital for the democratic good of society and it's because of this that it has the world's largest high-speed rail network, which it can then sell abroad at competitive prices.

In an attempt to conceal China's governing advantages and foresight, the corporate press labels Chinese-involved projects that don't reap immediate profits as "white elephants." Indeed, the debt trap narrative has been constructed to conceal the BRI's long-term planning and misdirect attention from private capital lending, which is far more severe than Chinese loans and the source of much suffering in the Global South.

Certainly, should the IMEC get off the ground without Chinese involvement and sell expensive Western infrastructure, then it will be interesting to observe the Western ideological apparatus scramble to justify how their venture is superior to the BRI, the initiative that the majority of the world has already voluntarily signed up to. There is still an open invitation for Europe, the US and India to join!

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.

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.

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.

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.

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.

Surgery has some surprisingly ritual roots.

Between around 6,000 and 4,000 years ago, skilled surgeons in southwestern Russia cut holes the size of silver dollars, or larger, out of the backs of people’s skulls. But the risky procedure wasn’t performed for medical reasons: These skull surgeries fulfilled purely ritual needs, a new study suggests. And those on the cutting end of the procedure usually lived.

Skulls of 13 people previously excavated at seven ancient sites in this region contain surgical holes in the same spot, in the middle of the back of the head, say archaeologist Julia Gresky of the German Archaeological Institute in Berlin and her colleagues. That’s a particularly dangerous location for this kind of skull surgery, also known as trepanation, the scientists report online April 21 in the American Journal of Physical Anthropology. It’s not an area of the skull typically targeted in ancient trepanations, which go back roughly 11,000 years in West Asia.
“There may have been an original medical purpose for these trepanations, which over time changed to a symbolic treatment,” Gresky says.

Archaeologist Maria Mednikova of the Russian Academy of Sciences in Moscow agrees that skulls in Gresky’s new study probably represent cases of ritual trepanation. She previously examined some of the same skulls. Trepanation may have been used in some ancient cultures as part of a rite of passage for people taking on new social roles, Mednikova speculates.

Carving a center hole in the back of peoples’ heads was a potentially fatal procedure. Surgeons would have needed to know precisely how deep to scrape or grind bone to avoid penetrating a blood-drainage cavity for the brain. They also had to know how to stop potentially fatal bleeding of veins nicked during surgery. The procedure must have been performed as fast as possible to minimize bleeding, the researchers suspect.

Yet 11 of 13 skull openings show signs of healing and bone regrowth, indicating that these individuals survived the operation and often lived for years after. The researchers identify six males and six females in the skull sample. One specimen’s sex couldn’t be determined from skull features.

Most individuals died between ages 20 and 40. One female with a layer of bone that had regrown from the inside border of a trepanation hole died between ages 14 and 16, suggesting her skull surgery had occurred as young as age 10, the researchers estimate.

CT scans, X-rays and analyses of bone surfaces produced no evidence of injuries or brain tumors that could have motivated surgery. Ancient skull surgery intended as a medical treatment often involved holes on the side of the head, near fractures from some type of blow to the head (SN Online: 4/25/08). It’s impossible to determine from bones whether trepanations were aimed at treating chronic headaches, epilepsy, psychological problems or difficulties attributed to evil spirits.

Other evidence, in addition to the risky and unusual location of trepanation holes, points to ritual skull surgeries in southern Russia, Gresky says. Many of these individuals were interred according to special customs, suggesting they ranked high in their societies. For instance, the skulls of seven people buried in a pit at one site had been grouped together near bundled fragments of limb bones in a special display. Incisions on the limb bones indicate that bodies had been dismembered after death before being ritually buried. Of the seven skulls, five display surgical openings at the back of the head. Another contains scrapes from a partial trepanation. Partial trepanations were probably intentional rather than unfinished, with their own cultural significance, Mednikova says.

Trepanation holes on the sides of another six skulls found at the same southern Russian sites were probably made to treat medical conditions, Gresky says. Surgical openings on several of these skulls are located near bone fractures.

Rituals and meanings attached to ancient trepanations in southern Russia will remain mysterious, Mednikova predicts. “We don’t know the myths and religions of tribes that lived there 6,000 years ago.”

Physicists of all stripes seem to have one thing in common: They love smashing things together. This time-honored tradition has now been expanded from familiar particles like electrons, protons, and atomic nuclei to quasiparticles, which act like particles, but aren’t.

Quasiparticles are formed from groups of particles in a solid material that collectively behave like a unified particle (SN: 10/18/14, p. 22). The first quasiparticle collider, described May 11 in Nature, allows scientists to probe the faux-particles’ behavior. It’s a tool that could potentially lead researchers to improved materials for solar cells and electronics applications.
“Colliding particles is really something that has taught us so much,” says physicist Peter Hommelhoff of the University of Erlangen-Nuremberg in Germany, who was not involved with the research. Colliding quasiparticles “is really interesting and it’s really new and pretty fantastic.”

It’s a challenge to control these fleeting faux-particles. “They are very short-lived and you cannot take them out of their natural habitat,” says physicist Rupert Huber of University of Regensburg in Germany, a coauthor of the study. But quasiparticles are a useful way for physicists to understand how large numbers of particles interact in a solid.

One quasiparticle, known as a hole, results from a missing electron that produces a void in a sea of electrons. The hole moves around the material, behaving like a positively charged particle. Its apparent movement is the result of many jostling electrons.

The new quasiparticle collider works by slamming holes into electrons. Using a short pulse of light, the researchers created pairs of electrons and holes in a material called tungsten diselenide. Then, using an infrared pulse of light to produce an oscillating electric field, the researchers ripped the electrons and holes apart and slammed them back together again at speeds of thousands of kilometers per second — all within about 10 millionths of a billionth of a second.

The smashup left its imprint in light emitted in the aftermath, which researchers analyzed to study the properties of the collision. For example, when holes get together with electrons, they can bind into an atomlike state known as an exciton. The researchers used their collider to estimate the excitons’ binding energy — a measure of the effort required to separate the pair.
The collider could be useful for understanding how quasiparticles behave in materials — how they move, interact and collide. Such quasiparticle properties are particularly pertinent for materials used in solar cells, Huber says. When sunlight is absorbed in solar cells, it produces pairs of electrons and holes that must be separated and harvested to produce electricity.

The researchers also hope to study quasiparticles in other materials, like graphene, a sheet of carbon one atom thick (SN: 08/13/11, p. 26). Scientists hope to use graphene to create superthin, flexible electronics, among other applications. Graphene has a wealth of unusual properties, not least of which is that its electrons can be thought of as quasiparticles; unlike typical electrons, they behave like they are massless.

Obliterating bacteria in the gut may hurt the brain, too.

In mice, a long course of antibiotics that wiped out gut bacteria slowed the birth of new brain cells and impaired memory, scientists write May 19 in Cell Reports. The results reinforce evidence for a powerful connection between bacteria in the gut and the brain (SN: 4/2/16, p. 23).

After seven weeks of drinking water spiked with a cocktail of antibiotics, mice had fewer newborn nerve cells in a part of the hippocampus, a brain structure important for memory. The mice’s ability to remember previously seen objects also suffered.
Further experiments revealed one way bacteria can influence brain cell growth and memory. Injections of immune cells called Ly6Chi monocytes boosted the number of new nerve cells. Themonocytes appear to carry messages from gut to brain, Susanne Wolf of the Max Delbrück Center for Molecular Medicine in Berlin and colleagues found.

Exercise and probiotic treatment with eight types of live bacteria also increased the number of newborn nerve cells and improved memory in mice treated with antibiotics. The results help clarify the toll of prolonged antibiotic treatment, and hint at ways to fight back, the authors write.
