The Owl Count

    Annie slept in the front of the seat with her father drovethrough the darkness. “We're almost there!” Dad announced cheerfully. “Soon we'll be observing and counting owls at the state park.” Yawning, Annie noddedand smiled. The time was 4:30 a.m. Looking out into the darkness, Annie remembered learning in school that most owls are active at night, when they hunt for food. During the day they sleep in hard-to-find spots.

    “Dad, why do you need to count owls?” she asked. “It's importantfor the scientists to have current information about bird populations,” he explained. “We want to know which birds have decreased in number and whether any new kinds of birds are coming into a certain area. You and I will write down the kinds of birds that we see today and keep a record of how many times we see each kind. Then we'll send out a report to a scientific organization that is collecting about birds from people all over the country.”

    Dad pulled into the parking lot of the state park. Then, with flashing in hand, they began their hike into the woods. Annie zipped up hercoat and tried to keep from trembling. She had not expected the morning to beso cold. Luckily her gloves were in her pocket.

    Suddenly Annie's father stopped and gestured for her to bestill. Obeying, Annie did not take another step. She thought she heard a low crying up head. “That's certainly a screech owl,” her father whispered. “Let's get a look at it.” After looking more closely, Annie could see that it was asmall owl. Sensing danger, the owl narrowed its eyes and pulled its feathers tightly against its body. Annie carefully wrote down in her notebook that theyhad seen a screech owl.

    Walking a little farther, they came to a tall oak tree. “Thislooks like a perfect spot to attract owls,” Dad said, “I'm going to play a recording of common call of the barred owl. Maybe we can get one to answer." Annie could hardly believe her ear. The recorded call sounded as if the birdwere asking, “Who cooks for you?” Moments later Annie thought she heard areturn call in the distance. She held her breath and waited. Suddenly a huge bird landed very quietly on a branch above them.

    Annie had long forgotten how cold it was. She stood in wonder, shining her flashlight on the bird and studying it carefully. The barred owl was nearly two feet tall. Grey feathers surrounded its dark eyes. The bird did not stay long, but it did not matter. Annie would never forget the image of the powerful barred owl.

    Movies are a great means of entertainment for many. There are some advantages of watching movies. Comedies, for example, help reduce your blood pressure. Laughter for 15 minutes during a film makes your blood vessels (血管) wider. Besides, when you watch a sad movie, you're more likely to come away from it thinking about loved ones and feeling happy about what you have.

    Watching movies can make you creative. A study shows that young children, who watched the use of magic in Harry Potter, score significantly higher in a creative thinking test than children who watched something else. Moreover, movies are very useful for strengthening people's mental health. They enable people to take time to really relax and temporarily forget about their daily concerns and problems.

    However, watching movies aren't always beneficial. Studies have shown that some people get real pleasure out of being scared by horror movies, but in various ways they may be risking their physical and mental health without even knowing it. When you watch a tense scene in a movie, your heart rate and blood pressure increase. Meanwhile this change in your brain chemistry reminds you of times when you were in a similar state, even if you have no idea you even had those memories. So if something horrible happens to you, being scared again by a movie can unintentionally make you experience it once more.

    Scientists, politicians and parents have debated for decades if being exposed to movie violence leads to actual real-life violence. Overall the answer to that is probably still up in the air, but a new study seems to prove that watching aggression on screen can contribute to being a bully (土霸) in real life, even if it is just in the short term.

    In conclusion, certain movies play a positive role, but not all movies do. It depends completely on the subject of the movie. So it's always advisable to choose the movies concerning something positive.

    Are you always disturbed by the noise made by your coworkers while you're working hard at your task? What kind of feelings will you have on hearing such kind noise? Have you ever got an idea that a certain helmet will help you out of the trouble no you can focus on your work at the office? Now, you needn't worry for the “Helmfon” will help you ignore noisy co-workers and other distractions.

    Created by Ukrainian design company Hochu Rayu, the Helmfon is a big helmet that uses special equipment to absorb the sound so as to completely block out any outside noise, giving the wearer their own quiet personal space so they can better focus their attention on their work. Made of a glass fiber shell, cloth and polyethylene（聚乙烯）, the helmet not only blocks outside sound, but it also keeps the noise you make in, allowing you to answer calls, hold Skype conferences, watch or edit videos, privately.

    The company came up with the idea for the Helmfon after being asked to design a new phone booth for an IT company. The project made the team think about the way we communicate and finally begin work on a device that would allow you to be in two worlds just sitting on your chair in the office, in a meeting, or everywhere you feel like just wearing your helmet.

    The Helmfon comes complete with a system board, microphone, speakers, and a special holder for your phone. The only trouble is that it makes you look like a character from Mel Brooks famous movie Spaceballs, but the company also made public a variety of great choices, including Bat man-inspired design, and even a Native American headgear.

    The Helmfon is still in prototype（维形）stage, but the Ukrainian company is already working on a commercially available design and plans to offer the design for sale. A release date has not yet been made public.

    It puzzled Emily when she was aware of something wrong. She tripped upon men's clothing "hidden" around her house.

    The 38-year-old woman says, at the beginning, she was confused to see quite a few photographs in her phone that she did not remember taking. She was the subject but something was different. Her friends started falling away and she did not know why. Her long-term relationship with her boyfriend also ended suddenly.

    Now she knows those men's clothing belonged to one of her "alternatives" and the same person was responsible for her closest friends' leaving her.

    In an interview, Emily said she was not allowed to name "the man" who takes over her body. She was not allowed to name any of her six alternative persons. She said, "I am aware that they are not real people, not physical people. They exist in an imaginative world. However, all those alternatives should be treated with dignity and respect."

    Emily has what's called Dissociative Identity Disorder（DID分离性身份识别障碍）, a condition characterized by the presence of two or more split personalities that have power over a person's behaviour.

    Her condition resulted from a car accident five years ago. It was August, 2012, when her vehicle broke down on the side of the road. A speeding driver crashed into her car. She wasn't physically injured but she suffered a mental condition caused by severe brain injury. Shortly after that, she discovered she wasn't alone inside her head. Switching between personalities happens frequently but there is no real pattern. It can be weeks between incidents then, for whatever reason, it happens more regularly.

    One of her alternatives is a smoker, even though she is not. Upon waking, she says there are messages in her head that she is a smoker. She describes her lifestyle as "isolated".

    "People consider DID as tragedy" she says, "I just want to make an effort to tell others that we deserve respect, that we are legally accepted members of society, and we hope to live a normal life. I'm not stupid, I'm not spiting or running around people with knives. I have a mental problem but try to live a normal life. I completed a course at Harvard, I wrote a book, I'm able to communicate well. I mother my two kids well. I'm not on welfare."

    Actually, she volunteers for an organization helping children. She also spends time speaking out about her condition and has written a book on the subject, hoping to help others who are experiencing the same trouble.

    We can video chat with astronauts aboard the International Space Station and watch live footage from the frozen heights of Everest. But communicating with a submarine (潜艇）or a diver is not so easy. The lack of practical methods for sharing data between underwater and airborne devices has long been a frustration for scientists. The difficulty stems from the fact that radio signals work perfectly in air travel but poorly in water. Sonar (声呐）signals used by underwater sensors reflect off the surface of the water rather than reaching the air.

    Now, researchers at MIT have developed a method with the potential to revolutionize underwater communication. "What we've shown is that it's actually feasible to communicate from underwater to the air," says Fadel Adib, a professor at MJT's Media Lab, who led the research.

    The MIT researchers designed a system that uses an underwater machine to send sonar signals to the surface, making vibrations (震动)corresponding to the ls and Os of the data. A surface receiver then reads and decodes these tiny vibrations. The researchers call the system TARF. It has any number of potential real-world uses, Adib says. It could be used to find downed planes underwater by reading signals from sonar devices in a plane's black box and it could allow submarines to communicate with the surface.

    Right now the technology is low-resolution. The initial study was conducted in the MIT swimming pool at maximum depths of around 11 or 12 feet. The next steps for the researchers are to see if TARF is workable at much greater depths and under varying conditions—high waves, storms, schools of fish. They also want to see if they can make the technology work in the other direction— air to water.

    If the technology proves successful in real-world conditions, expect "texting while diving" to be the latest underwater fashion.

    Misael is three times the size of other children at his age due to a symdrome(综合症 状) which means he is unable to stop eating.

    He is so heavy that he often stops breathing while sleeping — leaving his parents fearing that one day he may not wake up. His dad Manoel Abreu, 38, said, "Everything is hard for him — he is a baby carrying an adult's weight. His heart must be working under a lot of pressure. If he doesn't get the treatment he requires, there is a very good chance that he will pass away."

    Miseal, from Sanot, Brazil, was born a healthy 6lb 6oz, but immediately he started piling on the pounds. Doctors believe he may be suffering from Prader-Willi symdrome, a rare genetic condition that leaves him with greed. He now weighs a heavy 178lb and is still gaining despite following a low-fat diet and walking for 40 minutes each day.

    Mum Josiane, 37, said, "He has been putting on a lot of weight since he was a baby—even when I was breastfeeding him. But it was only when he was one and a half years old that we began to worry. He was gaining 3kg a month and was starting to get very heavy. We know we could lose him at any time. Sometimes when he is sleeping, I watch him to see if he is breathing. I cry a lot because we want to help him. But I am also very proud of him because he doesn't surrender(投降)."

    Misael visits a doctor every three months to try to control his condition, but currently there is no cure for Prader-Willi symdrome. Paediatric neurologist(儿科神经科专家)

    Lucio said, "Every time we meet, he has put on a lot of weight — sometimes up to 5 kg. I think Misael could get help from someone outside Brazil — both medically and financially — so that he can get the laboratory and genetic testing he needs."
