To most people, noise pollution is a jet flying over their head. For one Spanish woman, it is a neighbor playing the piano. The woman has taken her neighbor to court. Now she wants to send her neighbor to prison for over seven years on the charges of psychological damage and noise pollution.

    In a country known for its noisiness, the case has raised eyebrows. Neighbors often complain  about street noise in Spain, but people seeking prison time for someone practicing the piano is unheard of. At the trial, Sonia Bosom says she has been suffering noise pollution up to now due to the practice sessions of Laia Martin, who lives below her. Martin, 27, didn't admit that she played at home that often, saying she took regular classes in other towns and mostly practiced at home on the weekends.

    On the first day of the trial, the newspaper reported that Bosom told the court she now hated pianos so much that she couldn't even stand seeing them in a film. Bosom says years of hearing Constant playing has caused her “psychological injury”. Medical reports show she has suffered from a variety of problems, including insomnia (失眠), anxiety, and panic attacks.

    She says tests by local authorities have found that the sound levels made by the piano are up to 10 decibels （分贝）higher than the limit. City authorities have asked the family several times to either stop the piano playing or soundproof (隔音) the room. The family told the court that they carried out soundproofing work twice but the complaints continued.

    The court hasn't made a final decision. A spokeswoman says the trial will end before May.

    In 1869, the Smiley family purchased an area of land about 100 miles north of New York City. Over time, some of their property and much of the surrounding landscape became the Mohonk Preserve, which has since grown to 8,000 acres and attracts visitors and rock climbers.

    But the Mohonk Preserve also has a long scientific legacy. In the 1930s, Dan Smiley, a descendent of the original owners, began keeping track of the plants and animals that lived in the area.

    Megan Napoli is a research ecologist with the Mohonk Preserve in New York. She thinks Smiley's efforts produced a rare long-term data set of observations, which is useful for studying the impacts of climate change. For instance, other research has shown that songbirds are migrating north earlier and earlier in the spring.

    It's important for the birds to arrive at the proper time in the spring, because they need to time their arrival with the insect emergence. So they need to be here to establish their nesting sites, lay their eggs. Once the eggs hatch, they have their baby birds, so they need to time it when the insects are most abundant.

    Napoli has begun analyzing about 76,000 observations of songbird migration dates collected by Smiley and his team to see if they, too, show that climate change has altered the timing of migrations. Her results suggest that they do.

    Napoli found that short-distance migrants that spend their winters in the southern U. S. now arrive an average of eleven days earlier than they did in the 1930s. Long-distance migrants that overwinter in the tropics arrive roughly a week earlier. Napoli presented her results at a recent Ecological Society of America meeting in Portland, Oregon.

    Meanwhile, who knows how many other long-term, personal data collections like Smiley's are out there, waiting to be discovered and to help improve official attempts to track the planet's changes.

    Most young people enjoy some forms of physical activity. It may be walking, cycling, swimming, or in winter, skating or skiing. It may be a game of some forms—football, basketball, hockey, golf or tennis. It may be mountaineering.

    Those who have a passion for climbing high and difficult mountains are often looked upon with astonishment. Why are men and women willing to suffer cold and hardship, and to take risks in high mountains? This astonishment is caused, probably, by the difference between mountaineering and other forms of activity to which men give their leisure.

    Mountaineering is a sport and not a game. There are no man-made rules, as others, as there are for such games as golf and football. There are, of course, rules of different kinds which would be dangerous to ignore, but it is this freedom from man-made rules that makes mountaineering attractive to many people. Those who climb mountains are free to use their own methods.

    If we compare mountaineering with other more familiar sports, we might think that one big difference is that mountaineering is not a “team game”. We should be mistaken in this. There are, it is true, no “matches” between “teams” of climbers, but when climbers are on a rock face linked by a rope on which their lives may depend, there is obviously teamwork. The mountain climber knows that he may have to fight forces that are stronger and more powerful than man. He has to fight the forces of nature. His sport requires high mental and physical qualities.

    A mountain climber continues to improve in skills year by year. A skier is probably past his best by the age of thirty. But it is not unusual for men of fifty or sixty to climb the highest mountains in the Alps. They may take more time than younger men, but they perhaps climb with more skills and less waste of effort, and they certainly experience equal enjoyment.

    As scientists in the Netherlands tried to figure out how to build a super flying robot, they learned from one of nature s flyers: the humble fruit fly(果蝇).And by building this robot, they've gained new insights into how the fly carries out one of its dangerous tasks.

    The robot is called the DelFly Nimble Its wingspan(冀展)is about a foot wide. It has four wings that can beat at 17 times per second, which appear very delicate because they're made of the same material as space blankets.

    In the previous designs, they always had a tail, like a traditional airplane tail, said the robots main designer Matej Karasek. He's based at the Micro Air Vehicle Laboratory at Delft University of Technology in the Netherlands, and he and his colleagues published their findings on Thursday in Science

    “In the previous generations", he said, "flapping wings drove the robot forward while the tail helped to guide and stabilize it. But now the DelFly Nimble is completely controlled by the wings. The challenge then was actually combine the control into the wing movement, and that's what we achieved, Karasek said

    In the latest generation. the wings can each move individually or rotate(旋转)around the body of the robot in order to maximize the machine s agility(灵活 ) The robot can remain in one place in the air for about five minutes on a full battery or fly for more than a kilometer"， Karasek said, "And because the scientists are controlling all the movements, they can use the robot to learn more about how fruit flies actually carry out their dangerous tasks, which has caught the attention of biologists.”

    A so-called “smart drug” intended to improve people's cognitive (认知的) function to protect the brain from altitude sickness.

    Visiting high-altitude sites for work, spot, religious pilgrimages and military can result in cognitive effects, including memory loss and attention difficulties. There's little you can do to prevent these symptoms except acclimatize -but this takes time and doesn't always work. A drug called oxiracetam might be the answer.

    ShengLi Hu at the Third Military Medical University, Chongqing, China and her colleagues studied the performance of male military personnel at altitude. All lived in towns around 1,800 meters above sea level, During the study, they spent eight days at this altitude and then climbed for three days to reach 4,000 meters, where they stayed for up to a month.

    Twenty participants took oxriacetam three times a day for the first 15 days of the study, while another 20 received no intervention. The man did tests of attention and memory at the start and end of the study and 20 days in, by which time they had been at 4,000 meters for nine days.

    While all the participants experienced a drop in cognitive ability at 4,00 meters, those who took oxiracetam showed a much smaller drop than the control group.

    The team found that at high altitude the brain stem, which plays a critical role in supporting basic living functions, received blood at the expense of areas responsible for more advanced cognitive functions. But in people who took oxiracetam, blood flowing throughout the brain rose, thus offering more oxygen to these areas. This may be how the drug seems to lessen cognitive problems like with low oxygen.

    It isn't yet known whether diverting blood in this way could have negative effects in the long run. "The results are striking and imply that oxiracetam may be beneficial for helping to relieve cognitive ability decline caused by altitude." says Timothy Hales at the University of Dundee, UK.

Climbing, I once thought, was a very manly activity, but as I found my way into this activity, I came to see that something quite different happens on the rock.

Like wild swimming, rock climbing involves you into the landscape. On the rock, I am fully focused. Eyes pay close attention, ears are alert, and hands move across the surface. Unlike walking, where I could happily wander about absent-mindedly, in climbing, attentive observation is essential.

As an arts student studying English literature, I discovered a new type of reading from outdoor climbing. Going out on to the crags (悬崖), I saw how you could learn to read the rocks and develop a vocabulary of physical movements. Good climbers knew how to adjust their bodies on to the stone. Watching them, I wanted to possess that skillful "language".

My progress happened when I worked for the Caingorms National Park Authority.Guiding my explorations into this strange new landscape was Nan Shepherd, a lady too. Unlike the goal-directed mindset of many mountaineers, she is not concerned with peaks or personal achievement. Shepherd sees the mountain as a total environment and she celebrates the Caingorms as a place alive with plants, rocks, animals and elements. Through her generous spirit and my own curiosity, I saw that rock climbing need not be a process of testing oneself against anything. Rather, the intensity of focus could develop a person into another way of being.

Spending so much time in high and st ony places has transformed my view on the world and our place in it. I have come into physical contact with processes that go way beyond the everyday. Working with gravity, geology (地质学), rhythms of weather and deep time, I gain an actual relationship with the earth. This bond lies at the heart of my passion for rock climbing. I return to the rocks, because this is where I feel in contact with our land.
