Having trouble distinguishing one furry panda from another? A facial recognition app will make it easy for you. The app is developed by the China Conservation and Research Center for Giant Pandas along with researchers in Singapore Nanyang Technological University and Sichuan Normal University.
The image analysis research began in 2017. A database now contains about 120,000 images and 10,000 video clips of giant pandas. Close to 10,000 panda pictures have been analyzed and marked. Using the database, researchers are able to carry out automatic facial recognition on panda faces to tell one animal from another, the center said.
It's not just a gimmick(噱头) for tourists, though. Panda researchers hope algorithms and AI technology will help them analyze data on pandas both in captivity （圈养）and the wild. "The app and database will help us gather more precise and well-rounded data on the population, distribution, ages, gender ratio, birth and deaths of wild pandas, who live in deep mountains and are hard to track," said Chen Peng, a researcher with the base who co-authored a paper on "Giant Panda Face Recognition Using Small Database.""It will definitely help us improve efficiency and effectiveness in conservation and management of the animals," Chen said.
China has carried out four scientific field research project of giant pandas in the wild. The giant panda was scientifically discovered 150 years ago and named in the city of Ya'an, Sichuan. It remains one of the world's most endangered species. The number of captive pandas was 548 globally as of November last year. Fewer than 2,000 pandas live in the wild, mostly in the provinces of Sichuan and Shaanxi.
A survey of university students shows that those who place more online orders for food seem more likely to feel depressed. The Panel Study of Chinese University Students released by the Chinese Academy of Social Sciences surveyed students at 18 universities.
The survey found that time spent online in general had a significant impact on students' mental health. The longer a student spent online each day, the worse was the self-evaluation and the higher the likelihood of depression. For sleep quality, about 45 percent of student respondents gave themselves a score of 6 points out of 10. Data showed that 6.4 percent of university students order takeaway food online almost every day, followed by 16 percent who place orders 3 to 5 times a week and 21 percent who use the services 1 to 2 times weekly. Dr. Zhang Zhenyu, who participated in the research, said students on average had a self-assessment that rated their physical and mental health at 8.45 points. Over 36 percent scored more than 10 points on the CESD-10 depression scale. Zhang also found that 29.9 percent of students thought themselves "fat" or "very fat" and 54.3 percent said their appearance scored 6 out of 10.
According to the survey, 2.5 percent have had facial plastic surgery(整形手术) and 5.8 percent have plans to improve their appearance through surgery in the next three years. Among students who want plastic surgery and those willing to do it, girls take up to 64 percent and 79.8 percent respectively（依次）.
The survey also showed that 22.6 percent of students were left-behind children when they were kids, which research defines as children separated from their parents for six months in a row who had to be looked after by others. Zhang said the early experience of separation from parents had a negative impact on students' mental health and self-assessment scores. They also had higher depression scores than those who lived with parents.
The research team also found that students with good family economic conditions scored higher in all dimensions than students from poor families. Students with a good physical and mental status had strong time management and self-management abilities.
Notre-Dame de Paris, a cathedral church in Paris, is the most famous of the Gothic cathedrals of the Middle Ages. For the French, it represents something immortal, ever- present and unchanging, like a mountain. Built over almost two centuries, the Notre-Dame is, as President Emmanuel Macron said, "where the French lived all their great moments". Soldiers prayed here before leaving for the Crusades; Napoleon Bonaparte was crowned here; it survived the French Revolution, two World Wars and the Nazi occupation. It is where men bend their knees to profess love and thousands of tourists take photos every day.
A fire, whose cause was not identified yet, engulfed(吞没), on April 15th, the cathedral's upper structure. More than 400 firefighters took part in the 15-hour battle to control the blaze(火苗) that triggered sorrow over the globe. The extent of the damage is still unknown, but the fire destroyed much of the gothic cathedral's wood-timbered roof and spire(塔尖). The cathedral will certainly be restored (the French government promises), but the sight of flames bringing down the spire moved the world in a manner far exceeding its religious significance.
French Culture Minister Franck Riester on Thursday said the government would draw all the consequences from the huge flames that destroyed the centuries-old Notre Dame Cathedral, adding measures to protect the national heritage were on the table. "Staff from the fire department, the culture ministry and the city town hall rushed to the Cathedral, when the fire started, to protect the main artworks that were inside. The artworks, which include relics such as the Christ's crown of thorns and French king Saint-Louis's 13th century tunic, were first moved to the city town hall and will now be transferred to the nearby Louvre Museum ." the minister told Le Parisian newspaper in an interview without giving details on the possible measures.
As Artificial Intelligence (AI) becomes increasingly advanced, there are growing concerns that robots could become a threat. This danger can be avoided, according to computer science professor Stuart Russell, if we figure out how to turn human values into a programmable code.
Russell argues that as robots take on more complicated tasks, it's necessary to translate our morals into AI language. For example, if a robot does chores around the house, you wouldn't want it to put the pet cat in the oven to make dinner for the hungry children. "You would want that robot preloaded with a good set of values," said Russell.
Some robots are already programmed with basic human values. For example, mobile robots have been programmed to keep a comfortable distance from humans. Obviously there are cultural differences, but if you were talking to another person and they came up close in your personal space, you wouldn't think that's the kind of thing a properly brought-up person would do.
If only we can find a way to set out human values as clear rules, it will be possible to create more developed moral machines. Robots could also learn values from drawing patterns from large sets of data on human behavior. They are dangerous only if programmers are careless.
One simple check would be to program a robot to check the correct course of action with a human when presented with an unusual situation. If the robot is unsure whether an animal is suitable for the microwave, it has the opportunity to stop, send out beeps（嘟嘟声), and ask for directions from a human. If we humans aren't quite sure about a decision, we go and ask somebody else.
The most difficult step in programming values will be deciding exactly what we believe in moral, and how to create a set of moral rules. But if we come up with an answer, robots could be good for humanity.

It was a simple letter asking for a place to study at Scotland's oldest university which helped start a revolution in higher education. A 140-year-old letter 1 by a lady calling for her to be allowed to study 2 at St Andrews University has been discovered. Written by Sophia Jex-Blake in 1873, the seven-page document, which 3 the university to allow women to study medicine at the institution, was 4 yesterday on International Women's Day.
The document was discovered 5 in the university archives (档案) by part-time history student Lis Smith, who is completing her PhD at St Andrews University. She said, "We knew that Sophia Jex-Blake and her supporters, in their effort to 6 university medical education for women, had written to the Senatus Academicus(校评议委员会) 7 to gain permission to attend classes there, 8 we didn't know documentary evidence existed. While 9 the archives for information about the university's higher certificate for women, I was astonished to 10 what must be the very letter Jex-Blake wrote".
