The US and the UK's support for anti-China rioters exposed their ill intention to destabilize the Hong Kong Special Administrative Region (HKSAR), Chinese Foreign Ministry spokesperson Mao Ning said at Friday's regular press briefing, in response to the latest remarks by US and UK politicians regarding the issuing of arrest warrants for five fugitives that have fled the HKSAR to overseas.

China strongly deplores and firmly opposes certain countries' flagrant slandering against the national security law for Hong Kong and interference in the rule of law in the HKSAR, and the issuing of arrest warrants for the five fugitives is in line with international law and common practice, said Mao.

The National Security Department (NSD) of the Hong Kong Police Force said on Thursday that the police have put on the wanted list five individuals who have fled overseas and are suspected of having committed offences under the national security law for Hong Kong.

The five are Cheng Man-kit, Hui Wing-ting, Joey Siu, Fok Ka-chi and Choi Ming-da, according to the HKSAR.

The HKSAR government also on Friday strongly opposed and condemned certain countries' remarks on the issuing of arrest warrants for the five individuals.

The police issued arrest warrants of these five individuals according to the law, which is necessary and legitimate, said Mao. The national security laws of other countries including the US and the UK also have extraterritorial effect. These five individuals, under the pretext of "democracy" and "human rights," have engaged in activities that undermine China's national security, Mao said.

The Commissioner's Office of Chinese Foreign Ministry in HKSAR also expressed strong dissatisfaction and firm opposition on Friday. The spokesperson from the Commissioner's Office said that the extraterritorial application of the national security law for Hong Kong is fully in line with the principles of international law and common practice, and is a necessary and justified measure to ensure Hong Kong's long-term stability and order.

Meanwhile, the 2023 Implementation Rules for Amending the Implementation Rules for Article 43 of the Law of the People's Republic of China on Safeguarding National Security in the Hong Kong Special Administrative Region took effect on Friday.

"The amendments are technical in nature and the scope of the proposed amendments is extremely narrow: it only aims at making clear provisions in respect of the validity period of freezing notice, without changing the basis or principle for issuing such notice," said a spokesperson from HKSAR on Friday.

The amendments can make sure that the freeze notice of property related to offenses under the national security law for Hong Kong remains valid until the legal proceedings conclude, according to the HKSAR.

Lawmaker Elizabeth Quat Pui-fan supports the revision of the implementation rules. The lawmaker told the Global Times on Friday that it can "effectively combat serious crimes that endanger national security."

Anti-China figures are still using various means to deny and evade their crimes that endanger national security. The anti-China forces in the US and the West are eager to continue stirring up trouble and messing up Hong Kong, the lawmaker emphasized.

Authorities are launching a direct strike against anti-China elements and those who disrupt Hong Kong, by pursuing the criminal acts of Jimmy Lai Chee-ying and his peers in accordance with the law and freezing their assets. They have brought this upon themselves and HKSAR is obligated to handle it in accordance with the law, Quat said.

It is necessary to uphold the rule of law in governing HKSAR, using legal means to maintain stability and uphold social justice, the lawmaker said.

Mao, the foreign ministry spokesperson, reiterated that Hong Kong affairs are purely China's internal affairs that brook no interference from any external forces. China maintains firm resolve in safeguarding the nation's sovereignty, security and development interests. Relevant countries should respect China's sovereignty and the rule of law in HKSAR and stop interfering in China's internal affairs, she said.

China's university swimming team concluded their seven-day FISU Games campaign on a high note on Monday as they tallied 18 gold and two bronze medals to sit atop the leader board in swimming.

Butterfly specialist Zhang Yufei remains the biggest contributor to China's medal haul as she scored gold medals out of all nine competitions in which she participated. 

Monday night saw her win two gold medals in women's 50 meters freestyle and 4x100 meters medley relay at the Dong'an Lake Sports Park Aquatics Centre.

The Southeast University student was participating in the FISU University Games back-to-back with the World Aquatics Championships, which ended on July 30, a day before the FISU swimming competition began.

"The University Games competition is more like training for me. Even though I'm tired, I have to wake up when I step into the arena. Regardless of my mental state, once I'm on the competition stage, I have to give my all and take the race seriously," Zhang told reporters. 

The 25-year-old threw all the gifts she received at the award ceremony to the audience on Monday. 

Zhang, also a two-time Olympic champion and a two-time world championship title holder, said she is trying to get used to participating in back-to-back tournaments.

"It can be exhausting joining back-to-back events like the World Championships, University Games and the upcoming Asian Games, but it's all about building myself up," she said. 

"A significant portion of my training is done on dry land. Through these exercises, I enhance my physical fitness to improve my ability to compete in multiple events. Since I will be participating in many events at the Olympics next year, I started preparing from this year, making multiple races a habit for myself," she added.

Distance freestyle specialist Li Bingjie, 21, representing Shanghai Jiao Tong University, also had to swim back-to-back after winning the 400 meters freestyle. 

The last swimmer in the women's relay, she was struggling to stand thus was carried by her teammates after the final as her efforts ended with China leading the second-place Poland team with a one-second-sharp lead. 

Li, a Tokyo Olympics gold medalist and six-time world championship medalist, totaled eight gold medals at the FISU Games, including a clean sweep in the women's 400, 800 and 1,500 meters freestyle.

Li has said that she hopes to narrow the gap between her and the world's most decorated swimmer, Katie Ledecky of the US, in the lead up to the Paris Olympics, but she insists that she will continue to focus on her own rhythm rather than following others.

"I've made mistakes in this aspect before, allowing others' pace to dictate my pace, which ended in the later stages with me losing control of myself," Li told reporters. 

"Now I primarily focus on swimming according to my own rhythm."

Also that night, the Chinese university men's 4x100 meters medley relay team, headed by breaststroke world champion Qin Haiyang, set a new FISU record of 3:32.58 seconds. 

Speaking about the physical fatigue of participating in back-to-back races, Qin emphasized the importance of mental relaxation.

"My primary focus after training is on relaxing my mind. Physical fatigue can be recovered through a good sleep, but mental relaxation is more crucial because training is usually quite intense," Qin, whose given name Haiyang means "ocean," told reporters. 

"As my journey into swimming was also a serendipitous process, I feel that there is a sense of destiny associated with swimming," Qin said, speaking about his given name.

Qin thanked the home audience for their continuing support to the team. 

"The spectators are truly enthusiastic," Qin Said.

"Only during home games can you hear such fervent cheers and shouts!"

In addition to the release of new artworks, ULTILAND also bridges the gap between the real and virtual worlds in the name of art, transcending the boundary between WEB2 and WEB3 through innovative narratives and creating new value mappings.

Looking ahead to future plans, ULTILAND intends to establish a main island and themed islands. These themed islands will be overseen by artists and collectors, serving as hubs for art subjects, art creations, and more.

A decade since the first North American Shaolin Cultural Festival in 2013, the Shaolin Temple is once again hosting an official cultural exchange event in the US. 

The highly anticipated "2023 North American Shaolin Games" and a series of martial arts-related activities are scheduled to take place in Los Angeles, the US, on November 11 and 12.

The announcement was made during a press conference held on November 7. 

Organized by the renowned Songshan Shaolin Temple in China, in collaboration with the Shaolin North American Association, the games are expected to serve as a platform for kung fu enthusiasts to show off their skills and promote the popularization of the ancient sport in North America. 

Approximately 500 Shaolin disciples from over 40 states in the US, as well as from countries ­including ­Canada and Mexico will ­participate in the events.

Shi Yongxin, the abbot of the Shaolin Temple, said at the press conference that Shaolin kung fu is famous all over the world. 

Kung fu not only strengthens the body, but also uses martial arts to achieve Zen and enlighten people through wisdom. 

The kung fu competition is a long-standing tradition at the Shaolin Temple, which aims to enable Shaolin disciples to study more diligently and constantly surpass themselves, according to Shi.

During the opening ceremony, dignitaries from various fields will witness the top performers in various categories. 

The 2023 North American Shaolin kung fu stars - the top three in each discipline - will receive medals, trophies, certificates, and accolades as encouragement.

According to Shi, the tradition of Shaolin kung fu competitions has flourished overseas since 2011. 

Events like the European Shaolin Cultural Festival and the North American Shaolin Cultural Festival all regard the Shaolin kung fu competition as core content.

In 2022, the Shaolin kung fu online competition continued this tradition, uniting 5,320 participants from 94 countries and regions across six continents. 

Before coming to the US in 2023, the Shaolin Games had already been held in Zambia in Africa, Singapore in Asia, and Argentina in Latin America.

Shi, leading the visiting delegation, arrived in Los Angeles on November 1 to kick off a series of North American visits. 

During his visit to San Francisco on November 7, he delivered a speech titled "Zen Meets AI" at Meta's headquarters. 

In his address, he emphasized that while AI possesses remarkable data processing and analytical capabilities, and may display similar human perceptions through programs and algorithms, but it cannot replicate the awakened consciousness advocated by Zen Buddhism. 

He encouraged human beings to seek inner wisdom and ­transcendence, even in the face of AI advancements.

According to Shi, Zen ­Buddhism emphasizes that Zen practitioners can gradually improve their state of enlightenment through their own efforts. 

As a tool, AI can search and find relevant classics to solve various doubts that Zen ­practitioners encounter, providing assistance and convenience to Zen practitioners.

As US President Joe Biden is about to travel to Tel Aviv on Wednesday in a show of support to Israel as it prepares for a ground offensive in Gaza and with the aim to mitigate the expansion of the conflict between Israel and Hamas, analysts urged the US to shoulder its responsibility as a major power to act as a fair and impartial mediator and bring the two-state solution back on track.

US Secretary of State Antony Blinken, who announced Biden's trip to Tel Aviv, described it a demonstration of "US solidarity with Israel and our ironclad commitment to its security." During the meeting with Israelis, Biden also plans to hear what Israel will need to safeguard their security, Blinken said.

Before Biden reaches Tel Aviv, several US officials including Blinken and the top US military commander in the Middle East Gen. Michael E. Kurilla, have been engaging with senior Israeli officials in the country. The military commander is looking to "gain a clear understanding of Israel's defense requirements," according to the general's headquarters.

Ding Long, a professor at the Middle East Studies Institute of Shanghai International Studies University, told the Global Times on Tuesday that the purpose of Biden's visit to Israel is clear: Showing support to Israel, while working to prevent the conflict from escalating and spilling over to larger areas. What is worth noting is that these goals are not being worked toward out of consideration for Palestine's interests but to serve the interests of the US, he said. 

An uncontrollable Middle East means the US will have to haul the focus of its global strategy back to the region. Additionally, an escalated situation in the region will lead to skyrocketing oil prices and may exert a negative impact on the upcoming election next year, which all in all is not what the US is looking for, Ding explained. 

According to the White House, besides of meeting with Netanyahu and other Israeli leaders, Biden's trip will be followed by a stop in neighboring Jordan, where he will meet with Jordan's King Abdullah, Palestinian Authority President Mahmoud Abbas and Egyptian President Abdel Fattah el-Sissi.

Using international justice and international laws to address the Israel-Palestine conflict cannot be put into practice if the US fails to timely correct its Middle East policy and stop its one-sided support of Israel, and instead act as a fair and impartial mediator and bring the two-state solution back on track, Ding told the Global Times. 

The current round of conflict is the result of the US policy of putting the cart before the horse in the Middle East, for which the US should be held responsible. It is time for the US to reflect and correct its long-time failed Middle East policy, which has led the Middle East peace process astray, Liu Zhongmin, a professor at the Middle East Studies Institute of Shanghai International Studies University, told the Global Times.

Chinese experts urged the US to increase its promotion of Israeli-Palestinian peace talks and investment in the peace process, rather than trying to normalize Arab relations with Israel while the Israeli-Palestinian issue has not been resolved.
According to Al Jazeera, 10 days of bombing Gaza has caused widespread destruction of local schools and hospitals and displaced nearly 1 million people. 
The latest news from the BBC on Tuesday showed that more than 1,300 people in Israel have been killed by Hamas since October 7 and more than 2,700 people have died in Israeli retaliatory strikes in Gaza.

Regarding the current situation, China calls for a cease-fire and an end to the fighting as soon as possible in order to prevent it from spreading indefinitely and to avoid further deterioration of the situation, Zhang Jun, China's permanent representative to the UN, said after the UN Security Council on Monday failed to adopt a resolution proposed by Russia that would have called for a humanitarian ceasefire in Gaza and condemnation of all violence and hostilities directed against civilians. 

Five UN Security Council members voted in favor of the draft resolution, four members voted against it, and six members abstained. The proposal must receive at least nine votes in favor for the UN to adopt a resolution, with none of its five permanent members opposing or casting a veto, according to the UN.

The Chinese envoy expressed disappointment that the UN failed to pass a resolution on the Palestinian-Israeli issue but voiced support for the UN to continue to play its role and responsibility in prompting humanitarian aid. 

Some Western countries joining hands to vote against the UN resolution has thwarted the role the UN Security Council should bear to maintain international peace and security and resolve the current crisis, Ding said, highlighting that humanitarian aid should not be politicized. 

A most urgent task is to prevent the humanitarian catastrophe from worsening, however some Western countries are still attempting to leave more space for Israel to retaliate against Hamas. Their sinister intentions will not help the ceasefire nor ease the humanitarian disaster, Ding noted. 

While addressing the ongoing?crisis, the international community must adhere to the fundamental direction of the two-state?solution, work for?broader consensus?and formulate a timetable and road map to that end, the Chinese envoy noted. 

The Embassy of Colombia in China celebrated the country's National Day in Beijing, on July 27. The Colombian Ambassador Sergio Cabrera attended the event and expressed his willingness to maintain cultural exchanges with China. 

Ambassador Qiu Xiaoqi, Special Representative for Latin America and the Caribbean of the Government of China was the special guest at the event. Around 350 attendees, including representatives from diplomatic missions, party and state officials, representatives from provincial governments, and business people were also present at the event. 

Ambassador Cabrera delivered a speech at the event in which he said, "Culture, a sector to which I have been committed for all my life, is a tool for opening spaces for international dialogue. In China, our cultural agenda includes the planning of events in literature, gastronomy, plastic and visual arts, cinematography, and music."

Cabrera attended cultural and education promotion events in different cities around China in June. These included a conversation about Colombian literature and film in Southwest China's Chongqing Municipality and in Beijing, he talked about the Colombian film El olvido que seremos (Forgotten We'll Be) with Colombian writer Héctor Abad. During the visit, other activities carried out with the Foreign Affairs Office of the Chongqing Municipal People's Government included a live radio broadcast to promote Colombian music, showcasing songs from Colombia's most traditional musical genres such as Cumbia, Salsa, and Vallenato. It also included the well-known instruments such as the Caucasian flute which was the main instrument played to celebrate the friendship between Colombia and China at a concert in 2022. The ambassador also talked about Colombia's relations with China, especially with the city of Chongqing, and cooperation in education, culture, trade, and other areas.

The ambassador used an ancient and well-known proverb to demonstrate his country's friendly relations with China, says "Nothing, neither mountains nor seas, can separate peoples who share the same ideals and objectives." He said that, "China and Colombia are two nations and two peoples separated geographically but are unwaveringly united in our common goals and ideals in the pursuit of peace, harmonious development, environmental protection, and mutual benefit, and nothing can separate us." 

At the end of the event, the embassy served different Colombian cuisines such as coffee, chocolate and memorable Colombian traditional dances were also presented.

For ten years, China and Central Asian countries have been more tightly bonded together through cooperation in the traditional energy section under the Belt and Road Initiative (BRI). However, the rise of Chinese companies specializing in renewable energy and scientific institutes equipped with technology on ecological preservation has been greening the BRI in the past decade. 

By using Chinese technology and experience to monitor and improve the ecology of Central Asia countries, imparting local people the expertise to build a hydropower station, and kick starting a cutting-edge photovoltaic power plant to help generate substantial renewable energy in the region, Chinese institutes and companies are helping turn the dream of a "Green Silk Road" into reality, while also making China-Central Asia cooperation in the green sector a paragon for other countries. 

Ecological cooperation 

The Aral Sea, located between Kazakhstan and Uzbekistan, was once the world's fourth-largest lake. Farmland expansion, rising temperatures and a lack of water-saving technology caused the sea to shrink to just 10 percent of its original surface by the end of the 1990s. Large areas of the lake bed have become bare and covered with salt or salt crust. The health of local residents has also been affected, with a significant increase in the proportion of people suffering from leukemia, kidney disease, bronchitis, and asthma.

In recent years, scientists from the Xinjiang Institute of Ecology and Geography (XIEG) with the Chinese Academy of Sciences and Uzbekistan have been actively cooperating on the treatment of the Aral Sea. 

"The Aral Sea crisis is essentially a problem of an inland lake drying up due to excessive water extraction for agricultural irrigation," Li Yaoming, the director of the Research Center for Green Development of Silk Road at XIEG, told the Global Times. 

"China's Xinjiang region has also faced similar problems in the past, such as the management of the Tarim River. China has been implementing ecological water transfer from the Tarim River for many years and has relatively mature water resource management techniques, which can provide a reference for Uzbekistan," said Li. 

In the suburb of Tashkent, capital of Uzbekistan, stood a 5-hectare demonstration field for drip irrigation water-saving technology. XIEG participated in the project, established an observation station for plants, brought cotton and wheat seeds from China and used drip irrigation to improve plant productivity. 

The drip irrigation technology equipment and supporting farming machinery here are all from China, Shakhzod Saitjanov, a research fellow from the Institute of Genetics and Plant Experimental Biology of the Academy of Science of Uzbekistan, told the Global Times. He believes this project will elevate the quality of Uzbekistan's agriculture and boost the country's economy. 

"Traditionally, Uzbeks tended to use flood irrigation in cotton cultivation, which requires the use of a large amount of water to wash away the salt content in the soil. We have introduced new drip irrigation technology, which will help save a significant amount of water resources," said Li. 

In addition, Chinese scientists also helped in improving and managing saline-alkali land. They use salt-tolerant plants to reduce the salt content in the soil, creating conditions for growing other crops. Artificial forests are also planted on the sandy desert that formed after the drying up of part of the Aral Sea. All of these efforts play an important role in the protection of the Aral Sea.

Since the launch of the BRI, XIEG has conducted vast fundamental cooperation with regional countries in terms of improving the region's ecology. For example, the institute helped developed an integrated water-saving irrigation system for cotton in the Aral Sea region and a 25-hectare technology demonstration base has been established. The technology has been across a 200-hectare area. In 2021 and 2022, Uzbekistan found out that yields reached 404 kilograms and 414 kilograms per mu (0.06 hectare), respectively, while the water-saving rate reached 70 percent. Both yield and water-saving efficiency were more than double that of local cotton fields.

In Kazakhstan, XIEG introduced 32 species of plants with a total of 15,600 plants, and conducted training on planting techniques and irrigation measures. The institute completed the establishment of a 20-hectare protective forest belt demonstration zone, established a comprehensive health assessment system for man-made forests, and evaluated the ecological service functions of ecological barriers.

As the Earth is becoming hotter from global warming, inland and hydropenic Central Asian countries are facing severe environmental challenges. Such challenges are pushing China and Central Asia closer in cooperation in improving the region's ecological problems after the BRI was launched.  Ten years ago, people in Central Asia had little understanding of China's in water-saving and ecological protection technology. However, climate change has made them feel the urgency of environmental protection in recent years, said Li, noting that more and more research institutes and government departments in Central Asian countries have been approaching them, seeking cooperation.

He said that ecological protection has been gradually emphasized under the framework of the BRI and that he expects the governments of Central Asian countries to endow more support to relevant projects. 

Environmental protection was highlighted during the Xi'an Declaration of the China-Central Asia Summit, which concluded in Xi'an in May. As noted in the declaration, the Parties reaffirm the need for concerted efforts to ensure food security in a changing climate, and also note the importance of farming in the most environmentally friendly ways that support biodiversity, with the optimal use of water and land resources.

Li believes that the summit, as well as development of the BRI will be a turning point for China's environmental cooperation with Central Asian countries, as "collaboration in this field has been put in a higher position ever since."    

Teach a man to fish

The Tuyabuguz Hydropower Plant in Uzbekistan was the first project completed after leaders of China and Uzbekistan signed government-to-government energy cooperation during the Belt and Road Forum held in 2017 in Beijing. 

The project, contracted by Dongfang Electric Corporation (DEC), was completed within 14 months and put into operation in April 2019. As of August, a total of 109 million kilowatt-hours of electricity has been generated by the project. The station can achieve uninterrupted power generation for 11 months in a year, with an annual electricity output sufficient to meet the power needs of 1,600 households in Uzbekistan. It will become profitable within four years.  

Sun Jianfeng, a DEC project manager in charge of the station, told the Global Times on August 18 that "all power generation equipment in the project was manufactured in China, and the key technologies for the water turbines and generators were independently developed using Chinese intellectual property rights."

Sun introduced that the project was located downstream from the Akhangaran River's Tuyabuguz reservoir in the Tashkent region, which was originally used for irrigation. It was built at the location with the highest potential energy, which it fully utilizes to generate electricity, making it highly economical.

"The hydropower station maximized the utilization of energy during the irrigation process. Moreover, the project takes measures to prevent the flow of water from damaging crops or facilities," said Sun. 

The project's environmental friendliness not only embodies the generation of green energy, it also does not cause environmental problems like the construction of traditional dams, as it was built under an existing reservoir, introduced Sun.

Uzbekistan has shown enormous interest in renewable energy in recent years. The country has set an ambitious goal - generate 30 percent of its electricity from renewable energy sources by 2030.

Sun said that Uzbekistan government has been encouraging foreign investment into the renewable energy sector in recent years, which has created a friendly environment for Chinese companies. Meanwhile, Chinese companies' advanced technology in green energy also made them highly competitive in Uzbekistan. Thus, Sun believes cooperation between the two countries has great potential. 

In May 2022, Uzbekistan's investment committee and China's Ministry of Commerce reached an agreement to build a series of small and medium-sized hydroelectric power facilities worth a total of $2.7 billion, media reported.

Apart from exporting equipment, DEC is devoted to training local experts in the hydropower industry. Sun said his company held large-scale training sessions in 2018 and 2019. More than 60 Uzbeks took part in the sessions. 

"We taught them how to operate and maintain our equipment. The locals completed installation and debugging of our facilities during the final stage. The equipment has been functioning well and been well maintained during the past three years of operation," said Sun. 

"We did not send our people to the site for maintenance, we just provided guidance online. We sold our equipment and offered them our technology at the same time. There's an old idiom called 'give a man a fish and you feed him for a day; teach a man to fish and you feed him for a lifetime.' We taught them how to keep the project running for the next four or five decades, so the Uzbeks are going to operate it independently in the future," said Sun.

Meet local demands

Aziz, who works at the Zarafshan 500MW Wind Power Project, is always enthusiastic about her work. Whenever she encounters a problem, she relentlessly seeks answers from her Chinese colleagues. 

Aziz considers herself fortunate to have witnessed the installation of the first wind turbine at the Zarafshan wind power project in early June. This marks the first-ever wind turbine installation in Uzbekistan.

Constructed and run by SEPCOIII Electric Power Construction Co., Ltd. (SEPCOIII) in Zarafshan, Navoi Region, Uzbekistan, the Zarafshan wind power project is the first megawatt-scale wind power project implemented in Uzbekistan. With a total installed capacity of 500MW, it will also be the largest operational wind power project in Central Asia upon completion. 

Currently, the project is in its peak construction phase. Once completed, the project will provide sufficient green electricity for 500,000 households and save 1.1 million tons of carbon dioxide emissions annually, making a significant contribution to Uzbekistan's energy transition and sustainable economic development goals.

Uzbekistan's President Shavkat Mirziyoyev has implemented a series of reforms since taking office, of which new energy reform is an important part. According to the government plan, by 2030, the share of renewables in Uzbekistan's energy will reach 25 percent of the energy mix.

Aziz still vividly remembers the nationwide power shortage that occurred in early 2023. Despite the overall stability of the political situation and the upward trajectory of the economy in Uzbekistan, the country still faces challenges in meeting its growing electricity demand. 

However, Aziz feels optimistic about the future of energy development in Uzbekistan. Aziz's confidence in the future of energy development in Uzbekistan is shared by many. The government's commitment to addressing the power shortage issue and its efforts to attract investments in the energy sector have instilled hope among the population.  

"Uzbekistan is an important country along the BRI route, and the production and construction of photovoltaic, wind power and other new energy fields are the strengths of Chinese enterprises, so the prospects for cooperation between the two sides are promising," Ji Jun, manager of the project from SEPCOIII, told the Global Times.

'Green Silk Road' realized

A power station located in Kapchagay, Kazakhstan, co-invested and constructed by Universal Energy, a Chinese renewable energy company based in Shanghai and its Kazakhstan partners, marked the largest single photovoltaic power plant in Kazakhstan. Starting operation in 2019, the station is also the region's first large-scale new energy power station. 

With the model of "100 percent Made in China, 100 percent Construction in Kazakhstan," the project is able to generate electricity at a much lower cost than other similar power stations, and has substantially reduced carbon emissions. Wu Xiaoliang, deputy manager of the Universal Energy told the Global Times that "the station can generate 160 million kilowatt-hours on annual basis, equivalent to the electricity consumption of 50,000 households in Kazakhstan for one year. The project can reduce carbon emissions by 160,000 tons annually."

Wu also pointed out that in 2023, the company completed an international green certificate transaction with a large international trader, selling carbon assets generated from the 7,000 megawatt-hours of electricity generated by the Kapchagay power station, offsetting approximately 5,950 tons of carbon dioxide emissions. 

"The company has six newly built renewable energy power stations in Kazakhstan that have provided a total of 1.7 billion kilowatt-hours of green electricity to the local area, reducing carbon emissions by a total of 1.7 million tons."

In recent years, China and Central Asian countries have accelerated cooperation in the field of new energy such as wind power, solar power, and hydropower. According to data from China Power International (Kazakhstan) Investment Limited, by the end of 2022, the total installed capacity of a series of renewable energy projects invested and constructed by Chinese companies in Kazakhstan, including the Zhanatas wind power station and Turgusun hydropower plant, has exceeded 1,000 megawatts.

The accelerated cooperation is also aimed to cater for Central Asian countries' rising ambition in exploring usage of new energy. For example, Kazakhstan has made ambitious commitments to reduce the country's greenhouse gas emissions to 15 percent below their 1990 levels by 2030 and of reaching carbon neutrality by 2060.

Wu explained that Kazakhstan can realize self-sufficiency in providing electricity at the current stage, yet the country is facing the problem of an outmoded electricity infrastructure. 

"Most of the electricity-generation infrastructure was built during the Soviet era, which means their service time is reaching the limit. Insufficient maintenance and reinvestment in certain facilities are also evident. This means that if investment in the power sector is not increased soon, Kazakhstan may face significant power shortages in the coming years," said Wu.

Compared with companies from other countries such as Germany and Japan, Chinese companies' advantages are visible: Its leading photovoltaic technology, its deep connection with Central Asian countries and China-Europe freight train services have given such cooperation a better edge.

Wu said that the Kapchagay power station alone has more than 300,000 photovoltaic modules that were transported from China through China-Europe freight trains. The time and cost advantages brought by the China-Europe freight trains enabled the project to be completed and connected to the grid within only nine months.

China-Europe freight train services are helping China-invested wind power and photovoltaic power stations successfully land in Kazakhstan, which has accelerated exports of relevant Chinese equipment, and broken Europe's monopoly over Kazakhstan's new energy equipment, said Wu.

"The 'Green Silk Road' is becoming a reality," he said.

Over the ground lies a mantle of white — on Pluto. Snow-capped peaks on the dwarf planet dot an otherwise ruddy terrain. But these snowy summits appear to be composed of methane, not water, researchers report online March 3.

Mountain tops in Pluto’s Cthulhu Regio, a dark landscape abutting the planet’s famous heart, reflect more light than the surrounding area. The New Horizons spacecraft, which flew past Pluto on July 14, found that the bright regions correspond to surface deposits of methane. Mission scientists speculate that perhaps methane in the atmosphere on Pluto behaves like water in the air on Earth, building up on the ground as frost at the highest (and coldest) elevations.

Three Earth-sized planets orbiting a star practically next-door might be a good place to hunt for alien life — or at least check out some worlds that are different from anything in our solar system.

The planets orbit a dim, cool star just 39 light-years away in the constellation Aquarius. Each is outside or possibly on the edge of the star’s habitable zone — where average temperatures are just right for liquid water. But there could be niche locales on these worlds where alien life might thrive, Michaël Gillon, an astrophysicist at University of Liège in Belgium, and colleagues report online May 2 in Nature.
A year on the two inner planets lasts just a couple of days. Data on the third world are sparse; it could take anywhere between 4.5 and 72.8 days to trek around its sun. The star, designated 2MASS J23062928−0502285, is roughly the size of Jupiter — about one-tenth as wide as our sun — and about 3,200 degrees Celsius cooler than the sun. Such runts make up about 15 percent of the stars in the galaxy, though astronomers had not found planets around one before. All three planets were discovered as periodic dips in starlight in late 2015 using TRAPPIST, a telescope at La Silla Observatory in Chile.

If anything does crawl or grow on these worlds, it bathes in mostly infrared light. The innermost planets receive several times as much energy from their star as Earth does from our sun, which technically puts them outside the star’s habitable zone (SN: 4/30/16, p. 36). But the planets are huddled up so close to the star that gravity might keep them from spinning, creating a temperate zone along the line where day turns to night, the researchers suggest.

Faint red stars such as this one are the best place to look for warm rocky planets, says Nicolas Cowan, an astronomer at McGill University in Montreal. Planets, even small ones, are easier to see around these dim bulbs rather than sunlike stars. NASA’s planet-hunting Kepler space telescope has already shown that planets exist around similar stars, but those are too far away to investigate further. “This [study] finds a nearby example,” says Cowan.

Being nearby is important for studying the atmospheres of such worlds, or learning whether they have atmospheres at all. They may not. Red dwarf stars take a long time to form; planets arise while their sun is still a puffy, temperamental ball of contracting gas. “That might bake off all the water and the atmosphere,” Cowan says. Astronomers won’t know, though, until they point some big telescopes toward these worlds.

The Hubble Space Telescope might be able to get a crude look. But NASA’s James Webb Space Telescope, scheduled to launch in 2018, could gaze at these planets and measure how much starlight is being absorbed by molecules in their atmospheres. If there is an atmosphere, James Webb could look for such gases as oxygen and methane (SN: 4/30/16, p. 32). On Earth, at least, those gases are produced by plants and microbes.

Whether or not life has found a home on these worlds, all offer a peek at unfamiliar environments. The two planets closest to the star, for example, are bombarded with more energy than Venus, notes Lisa Kaltenegger, an astronomer at Cornell University. “How would Venus evolve if you heat it up even more?” she asks. “We don’t have such planets in our own solar system, so it is really interesting to find out what such planets can be like.”

New sperm-catching beads could someday help prevent pregnancy — or enable it.

Researchers created microscopic polymer beads that mimic unfertilized eggs and trap passing sperm. The beads are coated in the sperm-binding section of a protein called ZP2. In mammals, ZP2 is found in membranes around unfertilized eggs; sperm must bind to the protein before entering the egg.

The beads could be used as short-term contraceptives, Jurrien Dean of the National Institutes of Health in Bethesda, Md., and colleagues report in the April 27 Science Translational Medicine. In the laboratory, human sperm attached to the beads within five minutes. The researchers then mixed 100,000 human sperm with 1.5 million beads and 28 mouse eggs containing human ZP2 proteins. After 16 hours, only one sperm reached an egg.
In another experiment, beads coated with mouse ZP2 delayed pregnancy when injected into the uteruses of mating female mice. Bead-free mice took just over 28 days, on average, to conceive and give birth; bead-treated mice didn’t have babies for nearly 73 days on average. The beads didn’t appear to cause swelling or damage, and treated mice were able to give birth again within five months.

The beads could also help combat infertility. In an egg-penetration test, researchers gently detached bead-captured sperm and pitted those sperm against a control batch of sperm that had not been exposed to the beads. More than half of eggs (mouse eggs with human ZP2) exposed to the bead-selected sperm ended up with three or more sperm attached to them; none of the eggs exposed to the control group snagged three or more sperm. In fact, the control group failed to penetrate 38 out of 50 eggs. So the beads could someday be used to select healthy sperm for assisted reproduction, the researchers say.

But it’s not clear if the ability to bind to ZP2 necessarily indicates a healthy sperm, says Andrew La Barbera, chief scientific officer of the American Society for Reproductive Medicine in Birmingham, Ala. “Sperm selection is a very complex undertaking because of the fact that sperm are very complex,” he says. “We don’t know what makes a good sperm.”

Contraception might be a more reasonable future use for the beads, although allowing fertilization of one in 28 eggs is underwhelming, La Barbera says. Birth control should be closer to 99.9 percent effective. “It only takes one sperm to fertilize an egg,” he says. Still, the beads’ performance at blocking pregnancy in mice seems promising, La Barbera says. Future experiments would need to determine if the beads are safe and effective in women, and how many beads are needed to prevent conception.

Dean notes that the study is a proof of principle. Many unknowns must be evaluated before using the beads for birth control, including the side effects of long-term use, he says. “Although promising, we are a long way from translating these basic laboratory observations into useful clinical applications that provide people with better reproductive choices.”
