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.

(1)、What did Bohmann initially think of the experiment?
A、It could be a failure. B、It wouldn't take long. C、It wasn't original. D、It would cost much.
(2)、 Why did the scientists look for animal DNA in the zoos?
A、They raised many rare animals there. B、The zoos were specially built for them. C、They could collect enough animal DNA.     D、They could recognize animals confidently.
(3)、 How was the two teams' relationship when they learned of each other's work?
A、Competitive. B、Inseparable. C、Cooperative. D、Casual.
(4)、Which of the following is a suitable title for the text?
A、Research Teams Test DNA in Nature B、DNA in the Air Helps identify Animals C、Different Zoos Conduct DNA Studies D、eDNA Protects Endangered Animals

    Auckland is New Zealand's largest urban area with a population of just over a million people. It is not, however, the capital, although it was at one time, until the capital moved to Wellington. Auckland is the center of commerce and industry, and is perhaps the most energetic, prosperous and multicultural city in New Zealand.

    The city's landscape is decided by volcanic hills, the twin harbors, bays, beaches and islands. Its nickname “the city of sails” is very suitable. Auckland has more boats for each person than anywhere else in the world.

    Auckland has many volcanic hills, many of which currently afford great views of the city. And Auckland's geography is such that shiny waters seem to attract people from every point. It is a water lovers' best place, with some of the best beaches, swimming, diving, fishing, sailing, windsurfing and water sports in the country.

    Wellington is the capital city of New Zealand. It is also the cultural, administrative and political center of the country. Two aspects of the city that will immediately strike any visitor are the harbor and hilly landscape. Everywhere you go, the sounds and the smell of the ocean hang in the air, and green hills and valleys wrap you in a bear-hug embrace. At night, Wellington offers a spectacular, shimmering(闪闪发光的) cityscape that is unlike almost anywhere else in the world. Even after seeing it for a hundred times, it takes your breath away.

    Wellington is a scenic, windy and diverse place. It has some of the best museums, art galleries, restaurants, and coffee houses in the country. It is the storehouse for the nation's historic, cultural and artistic treasures. Being the first place where European settlers arrived, it also boasts lots of historic streets and buildings.

    Wellington is host to an excellent Festival of the Arts every two years.

    Artificial intelligence keeps defeating human, it is making countless victories against human in different fields of life and trying to push human to the corner.

    Google's DeepMind has defeated the world's number one player Ke Jie. Human brain somehow has been replaced by a machine and scientists are working very hard on developing a human brain by implanting a chip and connecting it to the thick neuron that connects the two hemispheres of the brain. Well, who doesn't want to get his brain upgraded to be as smart as the brain of Albert Einstein or Charles Darwin?

    Humans will probably one day invent a brain that can be implanted in the human skull and reprogram all the human thoughts, but this invention doesn't seems to be happening in the foreseeable future since human brain took millions of years to evolve. Some scientists believe that human will defeat death in the next twenty hundred years but they can't really predict how long it's going to take to develop a human brain that can completely replace the natural brain.

    Despite of this accomplishment in the field of artificial intelligence, it couldn't crease people from believing that science can't stand alone. For instance, AI can imitate human brain and most of the time outperforms it, but there are still a lot of hidden secrets. AI outsmarted Ke Jie has consciousness unlike the AI, Ke Jie felt sad when he was defeated and buried his face in his hands but the AI didn't feel happy and celebrate his victory.

    The computer of 1960 is the same as the computer of 2017 in terms of consciousness, there is no signs so far telling us that there is an algorithm(运算)that can make a conscious computer and decipher (译解) its feelings. We can predict what the future will look like according to the past, especially from scientific point of view but the development of human brain seems unpredictable and unknown.

    Fish have different personalities which change as they experience life's highs and lows, according to British biologists.

    Researchers identified different "personalities" in their fish by observing the boldness(大胆) or shyness of individuals, according to The Nature. Like people, some fish are very confident in the face of novelty or conflict, while others are silent and fearful.

    The scientists selected particularly bold and shy rainbow trout(虹鳟鱼), and tested whether they changed their outlook depending on what life threw at them. They arranged some fish to fight and others to watch to see how both the participants and observers responded to victories and defeats. Winning or losing a fight, or even watching fellow fish overcome the difficulties influenced the future behavior of the creatures studied in the lab.

    The researchers made fish compete with much larger or smaller opponents(对手), to ensure that they would win or lose their fights. These bold fish that won their fights tended to be even bolder when later presented with a novel food item; losing their fight caused them to be much more cautious.

    Fish also learn by watching others. Bold fish watching a shy fish exploring a mystery object were much more nervous when later given a novel item for themselves.

    Predictably, shy fish that won a fight also gained more confidence, but surprisingly, shy fish that lost their fights also grew bolder when exploring strange new food, Sneddon said, adding that this could be due to what she calls a "desperado effect"(亡命徒效应).

    The new research suggests that animals can gradually adapt(使适应) their personalities. The results agree with the effects that life experience can have on humans.

    Plastics remain one of the most - used materials for making many things. Things made of plastics can be very strong and last a long time. Plastics are also much lighter than metal and can easily be formed into different shapes. Plastics can take hundreds of years to break down on their own. And very few kinds are highly recyclable.

    A team of researchers working at the US Department of Energy says it has created a kind of plastic that could lead to products that are 100 percent recyclable. It recently reported the discovery in a study in the journal Nature Chemistry.

    The researchers say the new material is a plastic polymer (聚合体)called polydiketoenamine, or PDK. The team reports the material can be broken down in parts at the molecular (分子的)level. It can then be built up again to form plastics of different shapes, textures and colors. The researchers say this process can be repeated over and over again—without the plastic material losing any performance or quality.

    "Most plastics were never made to be recycled," lead researcher Peter Christensen said in a statement. " But we have discovered a new way to assemble plastics that takes recycling into consideration from a molecular perspective. "

    Many plastics have different chemicals added to them to make them more useful and powerful. The problem is that these chemicals attach to the monomers (单体), which remain in plastics even after the material gets processed at a recycling plant. The research team reported that, with the newly discovered PDK material, the monomers could be recovered and separated from any chemical additives.

    Next, the researchers plan to develop PDK plastics "with a wide range of thermal and mechanical properties. These plastics could be used for many kinds of cloth, as well as things such as 3D printed materials and foams. In addition, the team is trying to include plant - based materials in the process.

Pleasanton Partnerships in Education Foundation (PPIE) was started in 1987 to raise money by organizing running events for local schools. Based in Pleasanton, California, a suburb of San Francisco, the non-profit organization recently hosted a family-focused fitness event for the community. "Our event helps to bring the community together," said Mindy Louie, events and outreach manager for PPIE. "We have more than 3,000 participants, hard-working volunteers and viewers."

This year's fitness event took place on April 30 at the Alameda County Fairgrounds. It featured races of two miles, five kilometers and ten kilometers. A new Kids Challenge consisted of a quarter-mile run to encourage younger children to participate. When asked to describe the run, 11-year-old Jeremy Louie said, "Fun, exciting and enjoyable." Jeremy added that he was happy to help support his school.

PPIE supports all 15 schools in the Pleasanton Unified School District, which include more than 14, 500 students and 800 teachers and staff. The nonprofit organization tries to fund programs affected by budget cuts, while encouraging fitness and athleticism. To date, the PPIE has raised over $1 million for the school district.

A local runners' group called the BURN Youth Development (B. Y. D.) participated in the fundraising. The B.Y.D. has since grown to more than 100 youth members, 30 of whom ran in April's PPIE event. Jerry Wu, the group's founder and lead coach, explained that the B.Y.D. was born to keep kids running. "Watching them running strongly and happily makes me smile every time," Jerry said.

Jerry encourages teamwork and teaches the students valuable running techniques. As a B.Y.D. member, Ollie Gu, an eighth grader, was one of the top finishers in the ten-kilometer run. He completed the race in 40 minutes and 46 seconds and won first place in the 12-to-15 year-old age group. "The race was extremely rewarding," Ollie said. "I'm looking forward to it next year."
