    So what is rewilding?

    Imagine our natural habitats growing instead of shrinking. Imagine species thriving, instead of declining. That's rewilding. Rewilding is ecological restoration and a little bit more. Rewilding offers hope for wildlife, humans and the planet.

    Why is rewilding essential for Britain?

    ●Our ecosystems are broken. The places where you would expect wildlife to thrive have been reduced to wet deserts. The seabed has been damaged and stripped of its living creatures.

    ●Our wildlife is disappearing. Many wonderful British species have declined catastrophically over the past century. We've lost more of our large mammals than any European country except Ireland.

    ●We need keystone species. These vital species, including top predator（食肉动物）,drive ecological processes. Their loss in Britain and around the world has worsened our living systems.

    ●Nature looks after us. Good ecosystems can provide us with clean air and water, prevent flooding, store carbon, and attract visitors. Rewilding can leave the world in a better state than it is today.

    What are challenges?

    Our "rewilding britain" is a long-term project. Of course it has its challenges. Many of us feel indifferent, because we have got used to the lack of native forests. Many farmers oppose the idea. They thought it a crazy idea to bring back predators to the country because they would start killing farm animals. It takes time to educate them. Above all, we need money! So we need your help!

Plastic-Eating Worms

    Humans produce more than 300 million tons of plastic every year. Almost half of that winds up in landfills(垃圾填埋场), and up to 12 million tons pollute the oceans. So far there is no effective way to get rid of it, but a new study suggests an answer may lie in the stomachs of some hungry worms.

    Researchers in Spain and England recently found that the worms of the greater wax moth can break down polyethylene, which accounts for 40% of plastics. The team left 100 wax worms on a commercial polyethylene shopping bag for 12 hours, and the worms consumed and broke down about 92 milligrams, or almost 3% of it. To confirm that the worms' chewing alone was not responsible for the polyethylene breakdown, the researchers made some worms into paste(糊状物) and applied it to plastic films. 14 hours later the films had lost 13% of their mass — apparently broken down by enzymes (酶) from the worms' stomachs. Their findings were published in Current Biology in 2017.

    Federica Bertocchini, co-author of the study, says the worms' ability to break down their everyday food — beeswax — also allows them to break down plastic. ＂Wax is a complex mixture, but the basic bond in polyethylene, the carbon-carbon bond, is there as well, ＂she explains, ＂The wax worm evolved a method or system to break this bond. ＂

    Jennifer DeBruyn, a microbiologist at the University of Tennessee, who was not involved in the study, says it is not surprising that such worms can break down polyethylene. But compared with previous studies, she finds the speed of breaking down in this one exciting. The next step, DeBruyn says, will be to identify the cause of the breakdown. Is it an enzyme produced by the worm itself or by its gut microbes(肠道微生物)?

    Bertocchini agrees and hopes her team's findings might one day help employ the enzyme to break down plastics in landfills. But she expects using the chemical in some kind of industrial process — not simply ＂millions of worms thrown on top of the plastic.＂

    Most of us feel very tired after working for eight hours a day, five days a week. When we get home, we watch at least one film because it's well-deserved and the only time we get to "relax" before going to sleep. Wake up and repeat. No wonder you feel tired. So how do you get out of this vicious circle? How do you restart your life?

    ⒈YOUR MINDSET

    "Oh man, another one of these self-improvement things. I hope I can do it, but I've tried these things before, and I just never stick to it."

    This was something I used to say to myself every time I try to start something new for myself. There's a fear-driven side of your brain which tells you, "You can't do this."

    What can you do? Well, the tip here is to talk to yourself like you're talking to a friend, or a coworker. So the next time you try something new, be kind to yourself like you would be kind to others. You are your own worst critic. But you can also be your firm defender.

    ⒉YOUR DIET

    If you are looking at what you eat for the reason to feel energized, then the general rules are:

    1) Eat when you're hungry. Don't eat when you're not.

    2) Be mindful when you eat. Chew at least 20 times. Let yourself taste and digest your food.

    3) Don't do three things at once when you're eating. Your body wasn't made for that.

    4) Preferably, eat "real" food. Eat what your great-grandmother would recognize as food.

    Don't let your days pass by in a boring way. Start by re-examining these key habits in your life to build a body that can start doing things you want.

    ⒊YOUR SLEEP

    Without enough sleep, we're basically going through the day drunk. This means tiredness, difficulty to respond quickly and smartly to anything that comes up. The sleeping hours needed for an average adult ranges from 7 to 9 hours.

    When the company was small, Google cared a lot about getting kids from Harvard, Stanford, and MIT. But Laszlo Bock, Google's former Senior Vice President of People Operations, said it was the "wrong" hiring strategy. Experience has taught him that there are exceptional kids at many other places, from state schools in California to those in New York. "What we find is that the best people from places like these are just as good if not better as anybody you can get from any Ivy League school," said Bock, who authored a book titled "Work Rules!"

    So what else does Google not care about:

    Grades: Google's data shows that grades predict performance for the first two years of a career, but do not matter after that.

    Brain-teasers: Gone are interview questions such as: Why are manhole covers (井盖) round? How many golf balls can fit in a school bus? "Our research tells us those questions are a waste of time," Bock said. "They're a really coachable skill. The more you practice, the better you get at it."

    Here's what Google does care about:

    Problem solvers: Your cognitive (认知的) ability, or how well you solve problems.

    Leaders: The idea is not whether you were president of the student body or vice president of a bank, but rather "When you see a problem, do you step in and help solve it?" and then critically, "Are you willing to let somebody else take over, and make room for somebody else? Are you willing to give up power?"

    Googleyness: That's what Google calls its cultural fit. It's not "Are you like us?" Bock said. "We actually look for people who are different, because diversity gives us great ideas."

    "What's most important is that people are intellectually humble, willing to admit when they're wrong, and care about the environment around them ...because we want people who think like owners not employees," Bock said.

    We spend a great amount of time listening to music. Most college students listen to music at least three or four times a week, and more than 50 percent of them go to at least one concert per year.

    According to new research, we may be born liking music, because human beings are born to find certain combinations of sounds attractive. For example, young children can recognize a familiar Song even when its key is changed. Similarly, they respond with more emotions to their mothers' singing than to their mothers' speech. Careful analysis of mothers' child-directed songs indicates that each mother's songs remain stable from one "performance" to the next, and this may encourage children's engagement with the songs.

    Research with adults suggests that music catches our attention by activating(激活) brain pathways that are most suited to processing music than to processing other kinds of sound. Specifically, music appreciation relies on the auditory cortex(听觉皮层) on the right side of the brain, which is specialized to process sound that characterizes music-in contrast to the left auditory cortex, which processes the stop-and-start bursts of sound that characterize speech.

    Although some Psychologists remain skeptical about whether music may have powerful effects on our thinking, a number of studies have shown that listening to music can increase people's spatial reasoning abilities Furthermore, It is clear that music can greatly influence our emotions. Personally significant music activates areas of the brain associated with pleasure and reward, the same areas that are activated by sex and good food.

    Researchers do not agree about how humans' abilities to process and enjoy music have come into being. Anyway, the next time you enjoy listening to a piece of music, remember that the most complex pieces of audio equipment are the ones between your headphones.

I recently spent half a weekend sitting on the sofa watching the Davis Cup. I thought about going for a run, but I did not want to miss the rest of the match. Soon it was starting to get dark, so I did not bother (费神). Whenever I watch tennis, I think how nice it would be to play it regularly. But I have been thinking that for almost 20 years without actually setting foot on a court. The evidence would suggest that I'm not the only one.

When a country or city competes to host an international sporting event, it often promises that more people will take up sports as a result. London was no exception. Tessa Jowell, who helped to bid for (申办) the 2012 Olympics for London, said that by 2012 two million more people would be physically active. And 60 percent of young people would be doing at least five hours of sports per week.

In the end, just over one-third of people in Britain take part in sports once a week. A report on Olympic and Paralympic influences has said that a big change in participation levels simply has not happened.

Why isn't there a big increase in people taking part in sports after most sporting events? Perhaps it is a mistake to assume a definite link between watching sports and playing it. While the games are on, they actually encourage people to do just the opposite — to spend whole sunny days not out playing sports, but inside sitting on the sofa with the curtains shut to stop the sun shining on the TV screen. We don't expect half the audience of a hit musical to apply to drama school the next day, yet we seem to expect it of sporting events.

The high-level performances on show only remind people that they could never match the excellent athletes in their sporting achievements even if they trained full time.

Maybe participation in sports is not the right thing to expect after a major sporting event. The Olympics can do many things, but maybe this cannot necessarily be one of them.
