BEIJING (Reuters) – With a cryptic message about UFOs and a picture of a missile launcher, China’s military has hinted that it has carried out a test of a new missile, after images of an object streaking towards the sky circulated on Chinese social media.
Do you believe in UFOs? China hints at test of new missile
Will China’s 600km/h maglev train bring air travellers down to earth?
- Unveiled in Shandong, prototype will be a first step towards ground-breaking high-speed travel that will rival passenger jets, project engineer says
China was a leader in technologies that included suspension, guidance, control and high-powered traction, Ding told Qingdao Daily.
“The test vehicle has been powered up and is in good order,” Ding was quoted by the newspaper as saying.
Taking Beijing-to-Shanghai by plane as an example, Ding suggested: “It takes about four-and-a-half hours by plane including preparation time for the journey; about five-and-a-half hours by high-speed rail, and [would] only [take] about three-and-a-half hours by maglev.”
While earlier reports suggested the prototype was expected to begin full-scale testing by 2020, it was unclear what Thursday’s unveiling meant for this timetable.
More maglevs would join the development project in the coming months, the team leader was quoted as saying, while mass production of the technology was likely by 2021.
In contrast to the optimism of the team at Qingdao, Chen Peihong, professor of economics at Beijing Jiaotong University and a transport analyst, was more circumspect about the future of maglev trains.
“The market has to be bigger. Technology alone cannot make [the concept] a success,” she said.
Plane or train: as high-speed rail link connects Hong Kong to 44 mainland Chinese cities, what are cheapest and fastest ways to get where you are going?
Public transport relied heavily on economies of scale, Chen said. Chinese cities including Jinan, Hangzhou and Chongqing were considering maglev lines, but even the longest – from Jinan to Taian – would not exceed 50 kilometres.
Chen said that electromagnetic fields from maglevs were greater than those from the lines that powered high-speed trains, while environmental worries might keep maglevs out of densely-populated areas.
There was a debate in China in the early 2000s about the benefits of a developing a maglev compared to high-speed rail, researchers on that project said. Rail was preferred by the government because it was an established technology and one that was cheaper to realise.
By the end of last year, China’s high-speed rail network extended to most of the country at a distance in excess of 29,000 kilometres, according to government figures, twice as long as the rest of the world’s high-speed rail lines combined. Spain’s high-speed AVE network was the second-longest at 3,100km.
Elsewhere, researchers in Chengdu, Sichuan province, said a vehicle inside a vacuum tube powered by a superconductor coil from a maglev train – a hyperlink – was in development. They expected the vehicle to reach speeds in excess of 1,000km/h as air was pumped from the tube and resistance to the speeding object gradually eliminated.

China’s lunar rover Yutu ends 60-year riddle of moon’s mantle with discovery of mineral olivine
- Yutu’s discovery of olivine helps pave the way for scientists to confirm existence of a mantle beneath the moon’s crust
- Crystallised mineral likely came from a crater caused by a meteor strike

During its first mission on January 3, Yutu discovered olivine, a green, crystallised mineral usually found deep underground – like the upper mantle of the Earth – in surface samples collected near its landing site.
Further analysis showed that the olivine was not local, but had originated from a 72km diameter (45-mile) crater nearby.
The far side of the moon has more craters than the near side, which faces the Earth, and a meteor strike probably penetrated to the mantle and brought up materials to the surface.
“What we found is the first direct evidence of materials from deep below the lunar crust,” though how deep is still unknown, he said.
It is generally believed that the moon was once covered by oceans of molten rock. Lighter substances rose to the surface and formed a crust while heavier ones sank to form the mantle and core. The new findings support that theory.
China is the first country to land a rover on the far side on the moon and is planning to send a larger spacecraft there later this year to bring back samples.
The first Chinese astronauts will land on the moon between 2025 to 2030, according to Beijing’s latest schedule.
The Apollo missions brought back many rock samples, some of which contained olivine, but some scientists suspected they might have come from a volcanic eruption.
First photo of lunar rover leaving ‘footprints’ on moon
China, the United States and other nations have all announced plans to launch missions to exploit the moon’s resources within the next decade or two.
Yutu’s discovery could help scientists to draw a more accurate map of those resources, including the volume and distribution of minerals, researchers said.

US President Donald Trump gave Nasa an additional US$1.6 billion budget to put Americans back on the moon by 2024.
Li said Chinese scientists were willing to work with their colleagues in the US, but Washington had blocked any such collaboration.
“Our door remains open,” he said.

Could caped dinosaur found in China glide like Batman?
- 163-million-year-old fossil represents something new in evolutionary history
- Researchers say discovery is extraordinary
Researchers say the finding is extraordinary, representing something new in evolutionary history.
The little tree-climbing dinosaur – about the size of a magpie – was equipped with a soft, smooth membrane draped over its long, strong forearms that may have looked like the wings of a bat when spread.
Lead author Dr Wang Min, a researcher with the Chinese Academy of Sciences’ Institute of Vertebrate Palaeontology and Palaeoanthropology in Beijing, said quite a number of dinosaurs had birdlike feathers and some eventually evolved into birds.
“But bat-like wings? The idea has not been widely accepted,” he said.
The possibility was first raised a few years ago when a close relative of the newly discovered dinosaur was found, also in China, with a finger bone which had never before been seen in dinosaurs.
Why on earth, some critics argued, would a dinosaur need membrane when it already had feathers?

Ambopteryx longibrachium, nonetheless, had the same peculiar finger bone, only this time scientists were also able to observe a large membrane and a thick layer of hair over its head, neck and shoulders.
The hair and membrane was not an efficient combination for flight aerodynamics. But “in evolution, nothing is impossible”, Wang said.
The tiny T. rex cousin that humans could look down on
The dinosaur lived in thick forest and could have been easy prey to large predators. But its wings might have given it the ability to hop from tree to tree, and they could also have been useful when hunting.
Wang and his colleagues found traces of small bones in the remnant of its stomach. While a tree-climbing dinosaur’s main diet should have been fruit, it could sometimes hunt as well, according to the researchers.
An absence of a large chest bone suggested the dinosaur could not fly at will, like a bird or bat. It remains unclear how long the species survived, but it eventually vanished, probably because of competition from better-equipped winged animals with all-feather or all-membrane wings.

World’s largest technical professional society bans Huawei staff from peer review of research
- IEEE’s ban has ignited a backlash from its Chinese members, resulting in calls to boycott the organisation
Zhang Haixia, a professor with the Institute of Microelectronics at Peking University, announced on her WeChat account on Wednesday that she was quitting IEEE because the decision to comply with the trade blacklist went “far beyond the basic line of science and technology” and challenged her professional integrity.
In a statement on May 30, the IEEE said it must comply with its legal obligations under the laws of the US and other jurisdictions and that compliance with regulations “protects the IEEE, our volunteers, and our members”.
It said Huawei employees are only barred from the peer reviewing process and that they can continue to participate in individual membership, corporate membership, enjoy voting rights and take part in a variety of other activities, including the submission of technical papers for publication.
Huawei said it had no comment about the peer review ban.
The issue between Huawei and IEEE has come amid a raging tech war between the world’s two biggest economies, which recently escalated when the US government placed Huawei and its affiliates under the US Entity List on May 16. That bars the Chinese group from buying hardware, software and services from American hi-tech suppliers without US approval.
A succession of major American technology companies, from Google and Microsoft to Intel and Qualcomm, have suspended their dealings with Huawei to comply with the US trade ban.
Growing disquiet in China as US steps up war on tech champions
US President Donald Trump has also signed an executive order barring US companies from using telecoms equipment made by companies that pose a threat to national security.
The trade blacklist, which is maintained by the Bureau of Industry and Security under the US Department of Commerce, identifies organisations and individuals believed to be involved, or pose a significant risk of becoming involved, in activities contrary to America’s national security or foreign policy interests.
A non-profit organisation founded in January 1963, IEEE had more than 422,000 members in more than 160 countries as of December 31 last year. More than 50 per cent of its members, who are rooted in electrical and computer sciences, engineering and related disciplines, are from outside the US.
Technology is true target of US attack on China, says diplomat
It also publishes around 200 transactions, journals and magazines, and sponsors more than 1,900 conferences in 103 countries.
There is no official data on how many IEEE members are based in mainland China. Public information online, however, showed that at least 80 Huawei employees are members of the organisation.
China’s biggest chip maker to delist from NYSE as US targets tech
In a statement released on May 16, IEEE said that as a corporation organised in New York, it must comply with its legal obligation under US laws. It said the US government’s export restriction covers not only physical goods and software but also technical information.
In the leaked IEEE email, the organisation warned its members of “severe legal implications” if they continue to use Huawei staff as reviewers or editors for the peer review process of its journals.
“IEEE is registered in the US, but we should suggest experts at all levels of IEEE to move its headquarters to places such as Switzerland,” said Zhou Zhihua, a leading computer science professor at Nanjing University and an IEEE fellow, in a post on microblogging site Sina Weibo. “More importantly, let’s show more support to China-produced English-language journals.”

Chinese scientists find link between acne and common cold
- Study of children prone to recurring colds identifies abnormally high presence of skin affecting bacteria
- More research needed but study holds out prospect of future treatments

Zhang said the research team had found an abnormally high presence of Propionibacterium phages – a signature virus which uses the bacterium as a host – in the clinical samples, and it was likely the large colonies of the microorganism had thrived in the sick children’s respiratory ducts.
The imbalance between different microorganism groups could lead to more frequent, prolonged inflammation and cause further damage on respiratory tissues, he said.
“Living environment can be something worth checking,” Zhang said, suggesting that parents could reduce unnecessary exposure of their children to Propionibacterium infections by keeping them from kissing faces with pimples.
The common cold kills four million children under the age of five worldwide every year.
Frequent recurrence of the common cold is not uncommon. Causes for the phenomenon remain very much unknown, in part due to the difficulty of obtaining a large number of blood samples from under-aged patients.
China is making better, cheaper drugs – and its reasons may surprise you
Zhang said some uncertainties remained following the study and cautioned that the results were imperfect. For example, the quality of some samples was not ideal, due to a long period of refrigeration, and the interactive mechanism between the bacterium and infection was not entirely clear.
The findings “should not be immediately applied in clinical practice,” Zhang said.
A confirmation study is underway to monitor the conditions of selected child patients over the next two years and, if the results are positive, a testing kit may soon be available to identify children more vulnerable to recurrent colds, he said.
Medical intervention such as therapy or drugs may also be developed to address the issue of bacterium imbalance.
Antibiotic overdose is a severe problem in China and rest of the world, Zhang said. “Hopefully our study will help find a precise target,” he added.

Tiananmen Square: What happened in the protests of 1989?
Image copyright AFPThirty years ago, Beijing’s Tiananmen Square became the focus for large-scale protests, which were crushed by China’s Communist rulers.
The events produced one of the most iconic photos of the 20th Century – a lone protester standing in front of a line of army tanks.
What led up to the events?
In the 1980s, China was going through huge changes.
The ruling Communist Party began to allow some private companies and foreign investment.
Leader Deng Xiaoping hoped to boost the economy and raise living standards.
However, the move brought with it corruption, while at the same time raising hopes for greater political openness.
Image copyright GETTY IMAGESThe Communist Party was divided between those urging more rapid change and hardliners wanting to maintain strict state control.
In the mid-1980s, student-led protests started.
Those taking part included people who had lived abroad and been exposed to new ideas and higher standards of living.
How did the protests grow?
In spring 1989, the protests grew, with demands for greater political freedom.
Protesters were spurred on by the death of a leading politician, Hu Yaobang, who had overseen some of the economic and political changes.
Image copyrigh AFPHe had been pushed out of a top position in the party by political opponents two years earlier.
Tens of thousands gathered on the day of Hu’s funeral, in April, calling for greater freedom of speech and less censorship.
In the following weeks, protesters gathered in Tiananmen Square, with numbers estimated to be up to one million at their largest.
The square is one of Beijing’s most famous landmarks.
It is near the tomb of Mao Zedong, the founder of modern China, and the Great Hall of the People, used for Communist Party meetings.
What was the government’s response?
At first, the government took no direct action against the protesters.
Party officials disagreed on how to respond, some backing concessions, others wanting to take a harder line.
The hardliners won the debate, and in the last two weeks of May, martial law was declared in Beijing.
On 3 to 4 June, troops began to move towards Tiananmen Square, opening fire, crushing and arresting protesters to regain control of the area.
Who was Tank Man?
On 5 June, a man faced down a line of tanks heading away from the square.
He was carrying two shopping bags and was filmed walking to block the tanks from moving past.
Image copyright GETTY IMAGESHe was pulled away by two men.
It’s not known what happened to him but he’s become the defining image of the protests.
How many people died in the protests?
No-one knows for sure how many people were killed.
At the end of June 1989, the Chinese government said 200 civilians and several dozen security personnel had died.
Other estimates have ranged from hundreds to many thousands.
In 2017, newly released UK documents revealed that a diplomatic cable from then British Ambassador to China, Sir Alan Donald, had said that 10,000 had died.
Do people in China know what happened?
Discussion of the events that took place in Tiananmen Square is highly sensitive in China.
Image copyright GETTY IMAGESPosts relating to the massacres are regularly removed from the internet, tightly controlled by the government.
So, for a younger generation who didn’t live through the protests, there is little awareness about what happened.

Delhi metro: Will free public transport make women safer?
Image copyright GETTY IMAGESThe chief minister of India’s capital Delhi created a minor sensation when he announced that women would no longer have to pay for public transport.
Arvind Kejriwal said that free rides on city buses and the metro would help improve women’s safety in the city.
Delhi reports some of the highest numbers of rape in India. The 2012 gang rape and murder of a student on a bus in the city sparked massive protests.
However not everyone is convinced that Mr Kejriwal’s proposal will help.
Dinesh Mohan, a transport expert with the Indian Institute of Technology in Delhi, told the BBC that making public transport free wouldn’t solve the problem.
“You need to think about the entire journey and not just the metro – you have to take into account how safe or unsafe sidewalks are and what the journey to the metro station is like in the first place. So if the idea is to make it safer for women, that experience has to be continuous. Safety can’t begin and end at the metro station. I don’t see any thought behind this initiative yet.”
The Delhi metro already reserves a coach exclusively for women on every train it runs.
On social media, the proposal caused a great deal of debate as well.
Many people, including economists and columnists, dismissed the idea and some women even said that they would continue to pay to ride the metro.

However the proposal also had its share of defenders.
Despite Mr Kejriwal’s announcement, women will have to wait a while to see if it is actually implemented.
The proposal still has to be approved by the federal government because it is an equity partner along with the Delhi government in the Delhi Metro Rail Corporation.
But Mr Kejriwal has said that the federal government’s permission is not necessary as the Delhi government will bear the cost.
Delhi transport minister Kailash Gahlot said since this qualifies as a subsidy, they did not require any such permission.
Some have dismissed the entire thing as a pre-election gimmick by Mr Kejriwal – Delhi will hold state assembly elections next year.
The Delhi Metro Rail Corporation has not officially reacted to the news. But the Times of India newspaper quoted a “source” in the department as saying that implementing the proposal, if it came to pass, would be “difficult”.
Architect and urban planner Sonal Shah said on Twitter that a number of factors had to be taken into consideration for women’s safety to be addressed effectively. She said that transport access was “not equal for men and women”, adding that a number of existing issues with public transport had to be addressed first.

Five bodies spotted in search for climbers missing in Indian Himalayas
NEW DELHI (Reuters) – Five bodies were spotted high on a mountain in the Indian Himalayas on Monday during an aerial search for eight climbers feared swept away in an avalanche last week, a government official said.
The search mission was now working on the assumption that all eight climbers had been killed, he said.
“We are trying to retrieve the bodies. We believe the other three will be nearby,” he said.
The climbers was attempting to climb an unnamed, previously unclimbed 6,477 metre (21,250 feet) peak near Nanda Devi when their route was hit by a “sizeable avalanche”, said the company that organised the expedition, Moran Mountain.
Jogdande, said the bodies were above 5,000 metres and the possibility of a second avalanche would make accessing the site difficult. It had not been decided whether a team would go in by air or on foot, he said.
“We’re considering both alternatives. Since the bodies are at high altitude it is inaccessible, it is still unstable terrain that could lead to a secondary avalanche. We’re working out a plan.”
“It has always been a dangerous place to go. Mount Everest is easier to climb,” he said.
A team would take at least a week to reach the area, Sanjay Gunjiyal, a senior police official involved in the mission, told Reuters.
Four climbers in the group had turned back and later raised the alarm about their missing colleagues. They were evacuated from their base camp by helicopter and were “fine and healthy”, said Tripti Bhatt, an official of the Uttarakhand State Disaster Response Force.
DEADLY SEASON
It has been one of the deadliest climbing seasons in the Himalayas for several years. More than 20 people have been killed in the mountains, including 11 on Mount Everest, the world’s highest peak that has been plagued by poor weather, inexperienced climbers and overcrowding.
Nanda Devi, at 7,816 metres (25,643 feet), and its sister mountain, Nanda Devi East, are among the world’s most challenging peaks and only a handful of people have climbed them.
The leader of the missing group, Martin Moran, was the first person to summit Changuch, another peak in the area, and was known as a “godfather” of guiding in the Himalayas, according to a video diary of Rob Jarvis, who accompanied him on that expedition in 2009.
“He was very well versed with the area, but the route they were taking is not usually travelled,” Gunjiyal said.
Many of the other missing climbers are veterans but with little experience of Nanda Devi and its surrounding peaks, he said.
Indian authorities have identified the eight missing as Moran, John McLaren, Rupert Whewell and Richard Payne, all from Britain, Anthony Sudekum and Ronald Beimel from the United States, Ruth McCance from Australia, and liaison officer Chetan Pandey from the Indian Mountaineering Foundation.
