Some people believe that a Robin Hood is at work, others that a wealthy person simply wants to distribute his or her fortune before dying. But the donator who started sending envelopes with cash to deserving causes，accompanied by an article from the local paper, has made a northern German city believe in fairytales (童话）

    The first envelope was sent to a victim support group. It contained €10,000 with a cutting from the Braunschtveiger Zeitung about how the group supported a woman who was robbed of her handbag； similar plain white anonymous (匿名）envelopes, each containing €10,000, then arrived at a kindergarten and a church.

    The envelopes keep coming, and so far at least €190,000 has been distributed. Last month, one of them was sent to the newspaper's own office. It came after a story it published about Tom, a 14-year-old boy who was severely disabled in a swimming accident. The receptionist at the Braunschweiger Zeitung opened an anonymous white envelope to find 20 notes of €500 inside , with a copy of the article. The name of the family was underlined.

    "I was driving when I heard the news,” Claudia Neumann, the boy's mother, told DerSpiegel magazine. “I had to park on the side of the road； I was speechless. ”

    The money will be used to make the entrance to their house wheelchair-accessible .and for a course of treatment that their insurance company refused to pay for.

     “For someone to act so selflessly, for this to happen in such a society in which everyone thinks of himself, was astonishing," Mrs. Neumann said. Her family wonder whether the donator is a Robin Hood character, taking from banks to give to the needy.

    Henning Noske, the editor of the Braunschweiger Zeitung, said： “Maybe it is an old person who is about to die. We just do not know. ” However, he has told his reporters not to look for the city's hero, for fear that discovery may stop the donations.

    On October 17, 2016 the Shenzhou-11 manned spaceship was sent into space from the Jiuquan Satellite Launch Centre in Gansu. Two days later the spaceship successfully connected with the space laboratory Tiangong-2. It meant China got closer to its plan of building a space station in 2020.

    The spaceship took two Chinese astronauts to space this time. Jing Haipeng was an experienced astronaut who flew on Shenzhou-7 in 2008 and Shenzhou-9 in 2012. But it was Chen Dong's first space flight.

    Jing and Chen were given a 30-day task on Tiangong-2. They tested new technology and did experiments to prepare for future space station tasks. The astronauts themselves were also the subject (对象) of those experiments. The life support devices (设备) they used and how they lived inside the space laboratory were studied. No Chinese astronaut had stayed in space for that long before.

A month-long space task was not easy, so Chinese scientists and engineers had come up with lots of new technologies to allow astronauts to stay more safely and more comfortably in space. One of the new technologies tested during this task was a device called "space hospital". The space hospital was two little silver boxes tied around the two astronauts, legs. Through the "space hospital", scientists and doctors on the Earth could watch the astronauts, heart rate and temperature. When the astronauts felt tired, the "space hospital" could even massage (为…按摩) them.

    After this task, China was expected to send an unmanned cargo spaceship (无人货运飞船) in mid-April the next year. It docked with Tiangong-2 and took new fuel to the space laboratory.

    The hemlock(铁杉) trees along the Wappinger Creek, New York, look healthy. However, scientist Gary Lovett says the white balls which provide protection for the bugs are created by a tiny insect. It's hard to believe the tiny bug could kill a tree. However, trees can end up with millions and millions of the pests. When there are that many, it ends up killing the tree.

    The bug from East Asia is slowly killing trees across the USA. The trouble-making bug is just one of many invasive(入侵的) pests that have slipped into the United States. They can hurt other living things in their new home.

    Many invasive pests arrive on wooden pallets(运货板) piled inside shipping containers. They support and separate goods, and keep them from sliding around. Invasive pests often tunnel into the pallets. How can we stop pests from riding on pallets? Lovett says new rules are needed. The companies that make pallets don't want more rules. Congress has added an amendment(修正案) in the 2018 Farm Bill to try and prevent this problem. However, Lovett is not hopeful it will make much of a difference. Pallets are checked by inspectors. Many are sprayed with bug-killing pesticide. "I believe in the system," said Brent McClendon, president of The National Wooden Pallet and Container Association. He also said shipping containers are checked very carefully.

    Still, each year 13 million containers are shipped to the U. S. Each is full of wooden pallets. Lovett says: "Inspectors can't possibly check everything. All it takes are a few bad pallets; we should get rid of wooden pallets." He believes pallets should be made of plastic or eco-composite wood. Eco-composite wood is a mix of wood fiber and plastic. Insects cannot hide into it. One problem is that these choices cost more. They may be worth the extra money, though. Invasive pests cost the U.S. $5 billion a year. Trees don't just die in forests. They also die in cities and our yards. Then, they need to be replaced. That costs money, too.

    Robots that can chat, find misplaced glasses, draw airplanes and play with your children are attracting thousands of visitors during an expo in Tokyo as Japan adapts to changes in society.

    Robots, such as the sound-sensitive Chapit, answer simple questions and even joke with people to help the solitary fight loneliness and stay alert (机警的) in old age. "Many old people in Japan live alone and have no one to talk to," said Kazuya Kitamura, a representative of the expo organizer. "Communication robots stay together with old people and don't mind listening to the same stories over and over again."

    While Chapit, a relatively simple robot, managed to attract a partner, many researchers, such as Kiyoshi Matsumoto, a professor at the University of Tokyo, struggle to attract sponsors for more expensive projects.

    Matsumoto's "Personal Mobility Robot", equipped with four cameras and a sensor to recognize the user's centre of gravity, is designed to help the elderly move around without pressing buttons as in traditional wheelchairs.

    The robot can also help find misplaced glasses by recognizing them with a sensor. "We have developed a robot that can assist many people, but because of the high cost, we still haven't found a sponsor," said Matsumoto, who added that the cost of the machine, if produced in large quantities, would be comparable to that of a small car. "In the current economic environment there are few companies willing to invest (投资) in such a costly project," he said.

    Other robots, such as the award-winning "DiGRO", can support busy parents who have little time to play with their children. The robot can use the Internet to find a simple image and then draw pictures, looking after children while parents work.

    Japan is one of the world's fastest-aging countries and the government predicts that by 2050 the population of people over 65 will reach 40 percent.

    We work with Cambridge County Council's Participation Team to create opportunities for young people to visit the University and learn more about it. The following events are scheduled for the 2019/2020 academic year.

    SuperStar workshops

    12 workshops are planned for young people aged 7 to 11. These half-day visits will be held throughout the year, at times when young people are not at school. If participants complete 8 of the 12 workshops, they will be awarded the nationally recognized SuperStar Crest Award.

    Please note, workshops will only run if we have a sufficient number of attendees (usually around 3+ participants).

    Explore University Days

    Explore University Days are for young people aged 12-15. Participants visit the University for two days and take part in a variety of university-related workshops, and other fun activities.

    Previous participants have joined in the following:

    • Visited the Sports Centre

    • Took part in a Neuroscience workshop

    • Enjoyed a two-course meal at a University College

    Dates will be confirmed in early December 2019, and a schedule for event will follow in the New Year.

    Events for post-16 students

    If you are studying for your post-16 qualifications and are considering applying for Cambridge or would like to find out more about a specific subject, the following events might be for you:

    • University and College Open Days
