China's Shenzhou-19 astronauts return to earth
China has ploughed billions of dollars into its space programme in recent years in an effort to achieve what President Xi Jinping describes as the country's "space dream".
The world's second-largest economy has bold plans to send a crewed mission to the Moon by the end of the decade and eventually build a base on the lunar surface.
Its latest launch last week ferried a trio of astronauts to the Tiangong space station, heralding the start of the Shenzhou-20 mission.
They have taken over from Shenzhou-19 crew Cai Xuzhe, Song Lingdong and Wang Haoze, whose landing capsule touched down in the northern Inner Mongolia region on Wednesday.
Shortly after the landing, the Xinhua state news agency said the mission was a "complete success", adding that the trio were in "good health".
Pictures from state broadcaster CCTV showed the capsule, attached to a red-and-white striped parachute, descending through an azure sky before hitting the ground in a cloud of brown desert dust.
Teams of officials in white and orange jumpsuits then rushed to open the golden craft, and one planted a fluttering national flag into the sandy soil nearby.
The Shenzhou-19 crew had worked on the space station since October, where they carried out experiments and set a new record for the longest ever spacewalk.
They were initially scheduled to return on Tuesday, but the mission was postponed due to bad weather at the Dongfeng landing site, according to Chinese authorities.
Wang, 35, was China's only woman spaceflight engineer at the time of the launch, according to the Chinese Manned Space Agency (CMSA).
Commander Cai, a 48-year-old former air force pilot, previously served aboard Tiangong as part of the Shenzhou-14 mission in 2022.
Song, a 34-year-old onetime air force pilot, completed the group of spacefarers popularly dubbed "taikonauts" in China.
Bold ambitions
Last week, China saw off the Shenzhou-20 team in a feast of pomp and pageantry at the Jiuquan Satellite Launch Base in the barren desert of northwestern Gansu province.
A military band and crowds of flag-waving well-wishers bade farewell to the crew before they blasted off on a Long March-2F rocket.
State media reported that they assumed control of the space station after a handover ceremony with its former occupants on Sunday.
The all-male Shenzhou-20 crew is headed by Chen Dong, 46, a former fighter pilot and veteran space explorer who in 2022 became the first Chinese astronaut to clock up more than 200 cumulative days in orbit.
The other two crew members -- 40-year-old former air force pilot Chen Zhongrui, and 35-year-old former space technology engineer Wang Jie -- are on their first space flight.
During their six-month stint, the crew will carry out experiments in physics and life sciences and install protective equipment against space debris.
For the first time, they will also bring aboard planarians, aquatic flatworms known for their regenerative abilities.
China's space programme is the third to put humans in orbit and has also landed robotic rovers on Mars and the Moon as it catches up with the two most established cosmic powers, the United States and Russia.
Tiangong -- whose name means "celestial palace" in Chinese -- is its tour de force.
China has never been involved in the International Space Station due to opposition from the United States.
Washington plans to return to the Moon in 2027, though the election of President Donald Trump brought uncertainty over the mission's fate.

China's Premier Li Qiang says AI progress needs regulation, not just speed, calls for global cooperation
China's Premier Li Qiang called for urgent global consensus on artificial intelligence safety and governance, announcing a new international cooperation body. read more Chinese Premier Li Qiang is seen on a screen as he speaks at the opening ceremony of the World Artificial Intelligence Conference in Shanghai. AFP China's Premier Li Qiang warned on Saturday that the growth of artificial intelligence must be balanced against security risks, stating that global agreement was urgently required even as the technology race between Beijing and Washington showed no signs of slowing down. His comments come just days after US President Donald Trump launched an ambitious low-regulation policy aimed at solidifying the country's dominance in the rapidly evolving area, vowing to 'remove red tape and onerous regulation' that may stymie private sector AI development. STORY CONTINUES BELOW THIS AD Opening the World AI Conference (WAIC) in Shanghai on Saturday, Li emphasised the importance of governance and open-source development, announcing the formation of a Chinese-led body for international AI cooperation. 'The risks and challenges brought by artificial intelligence have drawn widespread attention… How to find a balance between development and security urgently requires further consensus from the entire society,' the premier said. He gave no further details about the newly announced organisation, though state media later reported 'the preliminary consideration' was that it would be headquartered in Shanghai. The organisation would 'promote global governance featuring extensive consultation, joint contribution and shared benefits', state news agency Xinhua reported, without elaborating on its set-up or mechanisms. At a time when AI is being integrated across virtually all industries, its uses have raised major questions, including about the spread of misinformation, its impact on employment and the potential loss of technological control. In a speech at WAIC on Saturday, Nobel Prize-winning physicist Geoffrey Hinton compared the situation to keeping 'a very cute tiger cub as a pet'. STORY CONTINUES BELOW THIS AD To survive, he said, you need to ensure you can train it not to kill you when it grows up. Pledge to share AI advances The enormous strides AI technology has made in recent years have seen it move to the forefront of the US-China rivalry. Premier Li said China would 'actively promote' the development of open-source AI, adding Beijing was willing to share advances with other countries, particularly developing ones. 'If we engage in technological monopolies, controls and blockage, artificial intelligence will become the preserve of a few countries and a few enterprises,' he said. Vice Foreign Minister Ma Zhaoxu warned against 'unilateralism and protectionism' at a later meeting. Washington has expanded its efforts in recent years to curb exports of state-of-the-art chips to China, concerned that they can be used to advance Beijing's military systems and erode US tech dominance. Li, in his speech, highlighted 'insufficient supply of computing power and chips' as a bottleneck to AI progress. STORY CONTINUES BELOW THIS AD China has made AI a pillar of its plans for technological self-reliance, with the government pledging a raft of measures to boost the sector. In January, Chinese startup DeepSeek unveiled an AI model that performed as well as top US systems despite using less powerful chips. 'Defining test' In a video message played at the WAIC opening ceremony, UN Secretary-General Antonio Guterres said AI governance would be 'a defining test of international cooperation'. The ceremony saw the French president's AI envoy, Anne Bouverot, underscore 'an urgent need' for global action and for the United Nations to play a 'leading role'. Bouverot called for a framework 'that is open, transparent and effective, giving each and everyone an opportunity to have their views taken into account'. Li's speech 'posed a clear contrast to the Trump administration's 'America First' view on AI' and the US measures announced this week, said WAIC attendee George Chen, a partner at Washington-based policy consultancy The Asia Group. STORY CONTINUES BELOW THIS AD 'The world is now clearly divided into at least three camps: the United States and its allies, China (and perhaps many Belt and Road or Global South countries), and the EU – which prefers regulating AI through legislation, like the EU AI Act,' Chen told AFP. At an AI summit in Paris in February, 58 countries including China, France and India – as well as the European Union and African Union Commission – called for enhanced coordination on AI governance. But the United States warned against 'excessive regulation', and alongside the United Kingdom, refused to sign the summit's appeal for an 'open', 'inclusive' and 'ethical' AI.

Over 25 lakh deaths averted worldwide due to COVID-19 vaccinations, study estimates
New Delhi: COVID-19 vaccines helped prevent more than 25 lakh deaths across the world between 2020 and 2024 -- for every 5,400 doses administered, one death was averted, estimates a study. Findings published in The Journal of the American Medical Association (JAMA) Health Forum "clearly demonstrate a major overall benefit from COVID-19 vaccination during the years 2020-2024", with 90 per cent of the life-saving benefits secured for the world's older adults. Researchers from the Catholic University of Milan, Italy, and US' Stanford University analysed publicly available data on worldwide population to estimate number of people who died due to COVID-19 and whether they died before or after getting vaccinated. "We compared this data with the estimated data modelled in the absence of COVID-19 vaccination and were then able to calculate the numbers of people who were saved by COVID-19 vaccines and the years of life gained as a result of them," author Angelo Maria Pezzullo, researcher in general and applied hygiene, Catholic University of Milan, said. The team also found that the 82 per cent of the lives saved by vaccines involved people getting the shots before encountering the virus, 57 per cent during the Omicron period, and 90 per cent of the lives saved involved people aged 60 years and older. COVID-19 vaccinations also helped save 14.8 million years of life -- a year of life saved for every 900 vaccine shots administered, the researchers said. Further, about three-quarters of the years of life saved were related to people aged 60 and above. "Before ours, several studies tried to estimate lives saved by vaccines with different models and in different periods or parts of the world," author Stefania Boccia, professor of general and applied hygiene at the Catholic University of Milan, said. However, "this one is the most comprehensive because it is based on worldwide data, it also covers the Omicron period, it also calculates the number of years of life that was saved, and it is based on fewer assumptions about the pandemic trend," Boccia said. The authors wrote, "In the main analysis, more than 2.5 million deaths were averted (one death averted per 5,400 vaccine doses administered). Eighty-two percent were among people vaccinated before any infection, 57 per cent were during the Omicron period, and 90 per cent pertained to people 60 years or older." In an invited commentary article, published in JAMA Health Forum, Monica Gandhi from the University of California San Francisco's Center for AIDS Research writes, "Vaccines save lives and the only way to get through this pandemic was always immunity; it is much safer to provide immunity to an older person through a vaccine than through natural infection." Gandhi added that in the prospect of a future pandemic, models such as the one used and presented in the study could help mitigate the damage caused by widely restrictive policies, yet allow protection for those needing it the most.
