Climate change to weaken Middle East wind energy: study
JERUSALEM, May 25 (Xinhua) -- Climate change is projected to reshape wind energy potential across the Middle East, with turbine-height winds weakening despite stronger ground-level breezes, according to a recent Israeli-German study.
The study, published Friday in the journal Climatic Change, predicted that coastal surface winds may strengthen by up to 0.7 meters per second by 2070, potentially easing extreme heat.
However, winds at 150 meters above ground -- critical for turbines to generate energy -- could slow by up to 1.0 meter per second due to changes in the regional weather system, reducing energy output by up to 7 gigajoules over six hours and impacting renewable energy plans and investments, the study showed.
One gigajoule is equivalent to 277.8 kilowatt hours (kWh).
Highlighting varying wind energy capacity in different regions in the Middle East, the study stressed the need to analyze wind patterns at multiple altitudes to avoid flawed energy forecasts.
The study urged policymakers to include future wind changes in their energy strategies, particularly by prioritizing resilient projects in high-potential regions like the Red Sea coast.

Chinese hybrid rice boosts food security in Madagascar
Song (back, third right) poses with local residents in Anosiarivo, Madagascar, on March 25, 2025. – Xinhua photo ANTANANARIVO (May 31): 'Before, our land barely produced enough to feed us. Now, with hybrid rice, we not only eat our fill, but sell the surplus and even save to buy more land,' a farmer called Femosoa Rakatondratsara told me, smiling beside his blossoming rice field. Mahitsy, a town some 35km north-west of Antananarivo, Madagascar's capital, is home to the Chinese Hybrid Rice High-Yield Demonstration Base. In the village of Anosiarivo, another hybrid rice site, vibrant paddies stretched to the horizon under blue skies and fluffy clouds. Ramboasalama Anolalaina Ratsina, an expert from the Ministry of Agriculture, was leading local farmers in pest control. Having twice received planting training in central China's Hunan Province, he is now a key figure in local hybrid rice promotion. 'All my planting skills came from Chinese experts,' he said. Over the years, Chinese experts in Madagascar have not only promoted quality seeds but also passed on knowledge, from hands-on fieldwork to theoretical training. Now, technicians like Ratsina are sharing that expertise with farmers across Madagascar. After Irene Nonenjanahary's first hybrid rice harvest brought in a bumper yield last year, she is more confident than ever. 'We used to rely on the weather,' she said. 'Now we rely on technology.' In 2007, China launched the hybrid rice demonstration center project in Madagascar, led by the Hunan Academy of Agricultural Sciences and Yuan's Hi-Tech Seed. It was one of the 10 agricultural technology demonstration centers pledged at the first Forum on China-Africa Cooperation. 'Farmers here relied entirely on the mercy of nature. Poor seeds, limited knowledge, and weak infrastructure meant many couldn't even grow enough to eat,' said Hu Yuefang, a Chinese agronomist.

To identify varieties suited to Madagascar's climate and soil, he and his team carried dozens of seed samples across almost every major rice-growing region of the island, eventually developing five locally adapted varieties with high yields, drought tolerance and flood resistance. 'But the real challenge was getting farmers to accept these 'foreign' seeds,' said Chinese agricultural expert Song Chunfang. To prove the benefits, they planted side-by-side demonstration plots – one with local rice, the other with hybrid. Using the same planting methods, the yield of hybrid rice was two to three times that of local varieties. Impressed by the yield, farmers dubbed it 'Tsarabe' – 'the best thing' in Malagasy. Hu recalled living in leaky thatched huts, collecting rainwater to drink, and trekking kilometres for firewood. 'Once, while transforming a swampland, a tree branch pierced my foot. It was the villagers who carried me out,' he said.

'I hope one day hybrid rice will be planted across Madagascar,' said Eric Laperozy, my Malagasy colleague. 'That way, more families can eat well, earn more, and my country can achieve food self-sufficiency.' – Xinhua China hybrid rice Madagascar Xinhua

China strives to cultivate tech-savvy generation in AI-driven classrooms
A student operates an AI-powered VR device at Shenzhen Xiantian Foreign Language School in south China's Guangdong Province on March 21, 2025. – Xinhua photo GUANGZHOU (May 30): In a junior high school classroom in the southern tech hub of Shenzhen, a 14-year-old student surnamed Geng deftly adjusted the parameters of a neural network model, having previously used his AI-powered 'study buddy' to refine the narrative flow of his essay. In this classroom, students have learned to see the world through the eyes of a neural network. They were taught how AI models recognise digits from 0 to 9 based on their unique shapes like identifying a '7' by its vertical line and horizontal stroke, or a '2' by its curved body and top bar. Once confined to tech startups, such a scenario is now becoming a required course in some Chinese schools, as the nation pushes to make AI literacy as fundamental as math or literature. China's education authorities have pledged to universalise AI education in primary and secondary schools by 2030. In Shenzhen's Longgang District, 18 schools were selected to pilot AI-driven projects, including personalised homework systems and AI-powered essay grading. After two months of data training, the AI system, developed by Feixiang Xingqiu, is now able to tailor assignments to each student's needs. In the first three months of 2025, the Beijing-based education tech startup piloted its digital courses in over 1,000 schools, reaching 150,000 students nationwide. 'AI simulates the formation of human intelligence through learning, integrating knowledge and generating cognition. Therefore, the first field it embraces is education,' said Xiong Zhang, a computing professor at Beihang University. Yet, early introduction to AI for children is debated. Many experts warn that chatbot interactions may weaken a child's natural sense of wonder. 'In an era where AI can replicate human knowledge, education should shift its emphasis,' said Bai Fengshan, a professor from Tsinghua University. 'Given this shift, education should prioritise 'exploring the unknown,' especially in early childhood, rather than emphasising the acquisition of existing knowledge,' explained Bai, cautioning against premature AI exposure for children. Students attend a PE class with AI-powered devices at Shenzhen Longgang District Arts and Science School in south China's Guangdong Province on Jan 3, 2025. – Xinhua photo At the Qing Shui School in the western suburbs of Beijing, educators are designing lesson plans to leverage the strengths of AI while mitigating its potential drawbacks. Fifth-graders were initially allowed to observe how giant archer ants find their nest in the wild. Then, they used DeepSeek to design experiments with sugar water 'odor bridges' and alcohol 'odor erasers' to guide ants along paths. However, the AI plan failed to simulate real ant nest odors accurately, causing the ants to deviate. After refining their design, the students successfully replicated ant colony algorithms and learned that these algorithms can optimise 5G base stations, robotic collaboration and community logistics routes. The core value of AI-driven educational reform lies in cultivating 'authentic problem solvers' for the intelligent age, said Cao Yanyan, an education official in Mentougou District of Beijing. 'The goal is for students to acquire not just knowledge, but also systematic thinking and innovative methodologies,' Cao added. – Xinhua AI China education Xinhua
