Most young architects—particularly those in big cities—can only dream about working in a building of their own. And making that dream come true often means finding a building no one else seems to want, which is exactly what happened to David Yocum and his partner, Brian Bell. Their building is a former automobile electrical-parts firm in Atlanta. From the outside, it looks too old, even something horrible, but open the door and you are in a wide, open courtyard, lined on three sides with rusting walls.

    In 2000,Yocum and Bell found this building in the city's West End. Built in 1947, the structure had been abandoned years earlier and the roof of the main building had fallen down. But the price was right, so Yocum bought it. He spent eight months of his off-hours on demolition, pulling rubbish out through the roof, because it was too dangerous to go inside the building. The demolition was hard work, but it gave him time to think about what he wanted to do, and “to treasure what was there—the walls, the rust, the light,” Yocum said. “Every season, more paint falls off the walls and more rust develops. It's like an art installation(装置) in there—a slow-motion show.”

    Since the back building had been constructed without windows, an all-glass front was added to the building to give it a view of the courtyard, and skylights were installed in the roof. The back of the building is a working area and a living room for Yocum and his wife. A sort of buffer(缓冲) zone between the front and the back contains a bathroom, a kitchen and a mechanical room, and the walls that separate these zones have openings that allow views through to the front of the studio and the courtyard beyond.

    Yocum and Bell, who have just completed an art gallery for the city, feel that the experience from the decoration of their building, focusing on the inside rather than the outside, has influenced their work. It has also given these architects a chance to show how they can make more out of less.

Evolution.

In 1978, I was 18 and was working as a nurse in a small town about 270 km away from Sydney, Australia. I was looking forward to having five fays off from duty. Unfortunately, the only one train a day back to my home in Sydney had already left. So I thought I'd hitch a ride (搭便车).

I waited by the side of the highway for three hours but no one stopped for me. Finally, a man walked over and introduced himself as Gordon. He said that although he couldn't give me a lift, I should come back to his house for lunch. He noticed me standing for hours in the November heat and thought I must be hungry. I was doubtful as a young girl but he assured (使……放心)me I was safe, and he also offered to help me find a lift home afterwards. When we arrived at his house, he made us sandwiches. After lunch, he helped me find a lift home.

Twenty-five years later, in 2003, while I was driving to a nearby town one day, I saw an elderly man standing in the glaring heat, trying to hitch a ride. I thought it was another chance to repay someone for the favour I'd been given decades earlier. I pulled over and picked him up. I made him comfortable on the back seat and offered him some water.

After a few moments of small talk, the man said to me, “You haven't changed a bit, even your red hair is still the same.” I couldn't remember where I'd met him. He then told me he was the man who had given me lunch and helped me find a lift all those years ago. It was Gordon.

    Tess was eight years old. Her little brother Andrew was very sick and their parents were completely out of money. She heard Daddy say to her tearful Mother, "Only a miracle can save him now."

    Tess took her money and made her way six blocks to Rexall's Drug Store.

    "And what do you want?" the chemist asked in an annoyed tone of voice. "I'm talking to my brother from Chicago whom I haven't seen for ages."

    "Well, I want to talk to you about my brother," Tess answered back in the same annoyed tone. "He's really sick. He has something bad growing inside his head and my Daddy says only a miracle can save him now. So how much does a miracle cost?"

    "We don't sell miracles here, little girl. I'm sorry but I can't help you," the chemist said, softening a little.

    "Listen, I can help you." The chemist's brother was a well-dressed man. He asked Tess, "What kind of miracle does your brother need?"

    "I don't know," Tess replied. "Mommy says he needs an operation. But my Daddy can't pay for it, so I want to use my money."

    "How much do you have?" asked the man from Chicago. "One dollar and eleven cents," Tess answered. "And it's all the money I have, but I can get some more, if I need to."

    "Well, what a coincidence (巧合)," smiled the man. "A dollar and eleven cents － the exact price of a miracle for your little brother. Take me to where you live. Let's see if 1 have the kind of miracle you need."

    That man was Dr. Carlton Armstrong, a surgeon in neurosurgery (神经外科). The operation was completed without charge and it wasn't long until Andrew was home again and doing well．

    Tess smiled. She knew exactly how much a miracle cost… one dollar and eleven cents… plus the faith of a little child.

Isatou Ceesay was born in 1972 in a small village in Gambia, Africa. As a teenager, Ceesay was forced to drop out of school because of poverty. She carried some goods with many girls like her to sell in the market to raise herself At that time, the plastic bags, being strong and light, became popular in Gambia. The problem was that people did not reuse the bags and simply threw them behind their homes. Over time, the houses were surrounded by trash.

Ceesay lived in such an environment for many years. She kept learning from the surrounding environment and planned to take action to change. In 1997, she started a recycling movement called One Plastic Bag in Gambia. She educated women in Gambia to recycle plastic waste into income for themselves. In the beginning, the movement had a mission to educate their village colleagues about the need to reuse garbage and recycle plastic waste, rather than letting the garbage increase behind their homes.

Over time, the movement became big and able to support and provide income for women around. It was also able to greatly reduce plastic waste in Gambia. But the work of collecting trash turned to be taxing. During the rainy season, plastic waste became wet and difficult to take, and after that it still took patience to dry it before it could be processed.

Ceesay said, "As a habit, people are used to pouring their garbage behind their houses, and because it is not visible, they forget it. But the bad effects again knock on your door very quickly — dirty air, various diseases and so on. Of course, if one man's house is clean but his neighbor's is not, then the man is also not healthy."

For 17 years, Ceesay has contributed to one of the most important problems about the plastic waste. In 2012, she got the TIAW Difference Maker Award in Washington, DC, United States. Her story was written into a book, which inspires many others to join or become makers of change in their own communities.

A key part of protecting endangered species is figuring out where they're living. Using environmental DNA, or eDNA, to track species isn't new. For a few years now, researchers have been using DNA in water.

Two teams of scientists — one in Denmark led by Dr Kristine Bohmann and one in the UK led by Dr Elizabeth Clare — came up with the same question at about the same time: Could they identify the animals in an area from DNA that was simply floating in the air? DNA in the air is usually so small that it would take a microscope to see it. "I thought the chances of collecting animal DNA from air would be slim though much time had been spent on it, but we moved on," said Bohmann who was trying to think of a crazy research idea for a Danish foundation that funds far-out science.

One team collected samples from different locations at Denmark's Copenhagen Zoo, and the other at Hamerton Zoo Park in the UK. Clearly, they both chose the zoos. "We realized we have the Copenhagen Zoo," Bohmann recalls. In fact, both the zoos in the UK and Denmark were almost like the zoos that were custom-built for the experiments: The animals in the zoos were non-native, so they really stuck out in DNA analyses. "If we detect a flamingo (火烈鸟), we're sure it's not coming from anywhere else but the zoo," Bohmann says.

In the laboratory, by comparing their samples with examples of DNA from different animals, the scientists succeeded in identifying many different animals at the zoos.

Neither team knew that the other team was working on a similar experiment. The two were nearing submission to a scientific journal when they discovered about the other experiment. Rather than compete to rush out a publication first, they got in touch and decided to publish their findings as a pair. "We both thought the papers are stronger together," says Clare.

"The next step is to figure out how to take this method into nature to track animals that are hard to spot, including endangered animals," says Bohmann.

On Nov 11, an Australian jockey (骑师) got hurt after his horse "broke down" during a horse race in Hong Kong. Though the jockey is safe now, his horse was not so lucky. Since the horse's leg injury would have led to its death, vets euthanized (实施安乐死) it in front of the audience on the spot. Falling off a horse at high speed has a big risk of injury. You can say it's the jockey's choice to take part in the sport. But what about the horses?

This is not the first time that animals have been harmed because of animal entertainment-related sports. For example, about 180,000 bulls (公牛) are killed in bullfights around the world, with many more injured in bullfight events every year, according to Human Society International, an organization promoting the human-animal relationship globally. Hunters shoot more than 800 lions in South Africa, reported World Animal Protection.

To help these animals, animal lovers have started many campaigns , which seem to be taking effect. In June, Churchill Downs, the site of the famous Kentucky Derby in the US, stopped all horse racing, originally set to run until July 

3. Circuses using animals have been banned by many countries around the world in recent years due to animal welfare worries, according to the website Four Paws.

Animals play an important part in our lives and are more than tools for sports and entertainment. The human-animal bond can be seen in all kinds of places. Service animals can help people in their jobs and animals are also used to help and care for people with illnesses and who have experienced abuse or mental illness. "We can have our sports, drinks, lively parties, and beautiful hats  but we can leave animals out of it," reported Vox.
