China's historic 23-day Chang'e 5 mission has not only obtained precious rock and soil samples from the moon, but has also brought back a group of seeds that traveled the furthest in the nation's agricultural and forestry histories. More than 30 kinds of seeds including that of rice, oats etc. , were placed inside the multi-module Chang'e 5 spacecraft and orbited around the moon for about 15 days.
Scientists wished to check what would happen to the seeds after being exposed to extraterrestrial（地外的）forces in lunar orbit and also hoped that they could develop beneficial mutations（突变）. This mission offered good opportunities to scientists, which enabled them to deepen their studies on the effect of cosmic rays on the growth and evolution of life on Earth.
Space-based mutation breeding refers to the process of exposing seeds to forces such as microgravity, vacuums and cosmic（宇宙的） radiation during a spaceflight and then sending them back to Earth for further observation and planting. Researchers observe and examine several generations of plants grown from space-bred seeds and investigate their mutations—some are positive and desirable while others are negative. Those with positive mutations will be kept and analyzed, and will be introduced to farmers after their certification and approval.
Space breeding can generate mutations faster and more conveniently than ground-based experiments and can bring about some desirable traits that are otherwise hard to introduce. Compared with natural or conventionally bred types of plants, space-developed versions with positive mutations usually feature higher nutritional content, greater annual yields, shorter growth periods and better resistance to diseases and insect pests.
China conducted its first space breeding experiment in 1987, using a satellite to carry seeds into space. Since then, hundreds of kinds of seeds and seedlings have traveled with dozens of Chinese spaceships. Space breeding has helped to produce more than 200 new types of mutated plants in China that have been approved for large-scale cultivation, ranging from grains to vegetables and fruits. The Chang'e 5 robotic mission returned 1. 731 grams of lunar rock and soil to Earth, marking a historic accomplishment 44 years after the last lunar substances were taken back.
In a country where over 80% of residents live in public housing, a government commitment to sustainable urban design could have huge influence. And when it's a tropical country like Singapore where convenience and air conditioning are a way of life, the impact could be greater still.
Promising 42，000 new homes across five residential districts,the eco-town of Tengah will be the 24th new settlement built by Singapore's government since World War Ⅱ. It is, however, the first with centralized cooling, automated trash collection and a car-free town center, with which environment lovers hope to offer a roadmap for reducing carbon emissions in the Southeast Asian city-state.
The development is named as "Forest Town" by officials, due to its abundant greenery and public gardens. Once home to brickmaking factories, and later used for military training, the 2. 7-square-mile site has been reclaimed by a forest in recent years. A 328-foot-wide ecological "corridor" will be maintained through its center, providing safe passage to wildlife and connecting a water catchment area on one side to a nature reserve on the other.
The project has proven a new plan for urban planners supporting green design principles and "smart" technology, according to Chong Fook Loong, group director for research and planning at Singapore's Housing and Development Board, the agency overseeing the country's public housing. "Tengah is a new start," he said in a video interview, explaining that roads and parking are being pushed beneath the town center. "We're going for the ideal concept of separated traffic, with everything underground and then the ground level totally freed up for pedestrians-for people. So, it's a very safe environment for all. "
"We want a town that allows walking and cycling in a very user-friendly manner," he added, saying that cycling has taken off" in Singapore in the "last three to five years especially". The master plan will see the installation （安装）of electric vehicle charging stations.

As the effects of climate change become more disastrous, well-known research institutions and government agencies are focusing new money and attention on an idea: artificially cooling the planet, in the hopes of buying humanity more time to cut greenhouse gas emissions.
That strategy, called solar climate intervention（干预）or solar geoengineering, involves reflecting more of the sun's energy back into space - abruptly reducing global temperatures in a way that imitates the effects of ash clouds flowing out from the volcanic eruptions. The idea has been considered as a dangerous and fancied solution, one that would encourage people to keep burning fossil fuels while exposing the planet to unexpected and potentially threatening side effects, producing more destructive hurricanes, wildfires floods and other disasters.
But,as global warming continues, producing more destructive hurricanes, wildfires floods and other disasters, some researchers and policy experts say that concerns about geoengineering should be outweighed by the imperative to better understand it, in case the consequence of climate change become so terrible that the world can't wait for better solutions.
One way to cool the earth is by injecting aerosols（气溶胶） into the upper layer of the atmosphere, where those particles reflect sunlight away from the earth. That process works, according to Douglas MacMartin, a researcher at Cornell University.
"We know with 100% certainty that we can cool the planet," he said in an interview. What's still unclear, he added, is what happens next. Temperature, MacMartin said, is an indicator for a lot of climate effects. "What does it do to the strength of hurricanes？" he asked, "What does it do to agriculture production？What does it do to the risk of forest fires？"
Another institution funded by the National Science Foundation will analyze hundreds of simulations of aerosol injection, testing the effects on weather extremes around the world. One goal of the research is to look for a sweet spot：the amount of artificial cooling that can reduce extreme weather events without causing broader changes in regional rainfall patterns or similar impacts.
Do you want to know how to learn from failures? Your journey starts this second. It takes courage for people to realize that they help on how to learn from failures. These following steps will assist you in learning from your mistakes and move on with your life.
A little bit of humility goes a long way. You know you did something wrong; and while you want to defend your mistakes, you had better keep your emotions in check. Accept that your plans don't go as well as you want and apologize to those who are under influence.
Humility is the first step to mend broken ties and relationships. Who you were before, or whatever your status might have been-those are no longer significant. This is not the time for you to start another war, but the time for you to reflect on what you have done.
Observe and report. If you want to learn from failures, then you need to stay quiet and start listening to other people. You might not have noticed these things before. Now that you're given the opportunity to observe them, you might be able to pick up a thing or two. This is your chance to learn how you can help straighten things out.
Make things right. It's not the most pleasant task to do, especially when you're cleaning up your mess. But making things right is extremely important to your redemption (补救). If you're not yet certain of what you can do, ask. Instead, you can start by helping out in little ways. Getting coffee for those who are under the influence, for example, is one way you can choose.
Knowing how to learn from your failures is very important.

Kids love percussion instruments （打击乐器）. In truth, becoming a percussionist requires a great deal of1and practice. It was believed that one more thing was vital—a good sense of hearing. Dame Evelyn Glennie,2, has proven that isn't always true.
At age 8, Glennie began taking piano lessons，and she also began losing her hearing. She was totally deaf when she joined her school orchestra （管弦乐队） at 12. The moment Glennie saw the3in the percussion section，she knew that was where she4. At 15，She5the Royal Academy of Music in London for a solo percussionist. However，never hearing of it, they were unsure about accepting her. Ever6, she persuaded them to take her.
Since Glennie made her first professional7in 1985, she has gained fame as the world's first fulltime solo percussionist and won many awards.
When asked how she8the music，she says，"I use all my9 ， especially sight，feeling and touch. " Paying close attention to the10and relying on feeling the music, she performs in bare feet on a wooden platform，which11her to feel vibrations（震动）from the instruments through the floor. She is in12motion as she moves from one instrument to the next.
She has become a（n）13wherever she performs. As a writer observed，"She was able to14disabilities aren't barriers. They're15to thinking differently. "
My Male Flatmates
For the majority of my adult life I have lived with mostly women. Our flatshares have been loud and intimate. But for the past year I have lived with two young men, who also happen to be my friends. It has been fascinating. In fact, I have spent a large portion of that time sitting in a dimly lit corner of the house, making notes, just so I can turn them both into a column. So, this is what I have learnt from my two darling boys.
The glassware shelf is incredibly exclusive in terms of quality, a situation brought about by the fact thatof my housemates are product designers. The glass itself must be thin and perfectly proportioned,(vote) into the cupboard like it's a private members'club. "Megan, have you seen this," said one of my housemates the other evening. He was standing in the kitchen, solemn and disappointed, holding a Buxton cider glass. "It (enter) our home. ""Yes," I said," it's a pint glass from a pub. ""Oh my God," he said, shaking his head. And I looked at the pint glass and thought: you are livingborrowed time, my friend. All I know is that poor glass will happen to go missing on a day when I happen(work) from the office.
Dating in a house of girls is essentially a group activity. you even get home your housemates want to know how he said hello, what drink he ordered andhe waited for the green man when you were walking back to the station. My male housemates, largely, don't give a toss. I have to loiter (wander) around their rooms asking them if they want to hear how it all(go), like a has-been celebrity desperate to share her old stories. When I was a bit heartbroken they didn't really know what to say - but they did go out to the shops, at a reasonable hour, cook me a fish pie,divide it into three and hand me huge mountain of food in my favourite bowl. They poured me a glass of wine in one of their fussy tumblers that looked bloody fabulous, and they sat either side of me on the sofa and said it'll get better, you know, and I love them very very dearly
