As we know, DNA testing is very useful for crime fighting. But now crime fighters could have a new tool at hand. Researchers have developed a cutting-edge (前沿的) technique to identify human hair. Their test is quicker than DNA analysis techniques currently used by the police.

    DNA testing is commonly used for identification because DNA is unique to each individual. However, environmental and chemical processes can degrade(降解) DNA, limiting its usefulness over time. Protein (蛋白质) in hair, on the other hand, is more stable than DNA but can also have variations (变异体) that may be unique to the individual.

     “Our analysis process can be used universally,” says Ms. Huang, “One of our samples even included dyed hair and the test was 100 per cent accurate. The test was able to distinguish East Asians, Caucasians and South Asians.”

    Dr. Beauchemin says she has got in touch with law enforcement agencies about using the new technology. She is also planning to collect more hair samples and continue her research with a goal of finding where exactly in the world hair sample is from, to look for more races and determine specific age.

     “We are in a very similar place with protein-based identification to where DNA testing was during the early days of development,” said chemist Brad Hart. “This method will be a game-changer, and while we've made a lot of progress toward improving it, there are steps to go before this new technique is able to reach its full potential.”

    I told my friend Graham that I often cycle two miles from my house to the town centre but unfortunately there is a big hill on the route. He replied, "You mean fortunately." He explained that I should be glad of the extra exercise that the hill provided.

    My attitude to the hill has now changed. I used to complain as I approached it but now I tell myself the following. This hill will exercise my heart and lungs. It will help me to lose weight and get fit. It will mean that I live longer. This hill is my friend. Finally I comfort myself with the thought of all those silly people who pay money to go to a gym and sit on stationery exercise bicycles when I can get the same value for free. I have a smile of satisfaction as I reach the top of the hill.

    Problems are there to be faced and overcome. We cannot achieve anything with an easy life. Helen Keller was the first deaf and blind person to gain a university degree. Her activism and writing proved inspirational. She wrote, "Character cannot be developed in ease. Only through experiences of suffering can the soul be strengthened, vision cleared, ambition inspired and success achieved."

    One of the main determinants of success in life is our attitude towards adversity （逆境）. From time to time we all face hardships, problems, accidents and difficulties. Some are of our making but many are no fault of our own. While we cannot choose the adversity, we can choose our attitude towards it.

    Douglas Bader was 21 when in 1931 he had both legs cut off following a flying accident. He was determined to fly again and went on to become one of the leading flying aviators in the Battle of Britain with 22 aerial victories over the Germans. He was an inspiration to others during the war. He said, "Don't listen to anyone who tells you that you can't do this or that. That's nonsense. Make up your mind, you'll never use crutches （拐杖） or a stick, and then have a go at everything. Go to school, and join in all the games you can. Go anywhere you want to. But never, never let them persuade you that things are too difficult or impossible."

    The biographies （传记） of great people are full of examples of how they took steps to overcome the difficulties they faced. The common thread is that they did not become depressed. They chose their attitude. They chose to be positive. They took on the challenge. They won.

    Nevertheless, there is still the problem of how you change your attitude towards adversity.

    Sydney has a huge bus system(系统). No buses accept cash, and a ticket needs to be bought ahead of time. The buses often run at busy hours and regularly(有规律地) during the day. The Sydney Explorer bus provides air-conditioned service and stops at 27 tourist attractions. Its partner, the Bondi Explorer, stops at 19 attractions. Tickets allow holders to jump on and off as they please, and they are valid(有效的) for one or two days. It's an easy way to see the city and the surroundings.

    Sydney's train service runs throughout the central city area and the surroundings. Tickets can be bought from machines that operate 24 hours a day or from ticket offices. The monorail(单轨铁路) travels through central Sydney. It is the most excellent way to gain a good view of the whole city. The monorail runs every three to five minutes, and it takes 15 minutes to complete its journey.

    Sydney is built around a harbor, and the Parramatta River has a large ferry（渡轮）system. It serves the area around the harbor. These include Taronga Zoo, Darling Harbor, Rose Bay, the North Shore, Cockatoo Island and Sydney Olympic Park. The ferries have operated for more than 135 years and 14 million passengers take the ferries each year.

    Water taxis can transport passengers to specific locations(地点), and offer guided tours of waterways. They also offer special services that some visitors may enjoy. The tickets sell for 20 AUD (Australian dollars)for a day or 57 AUD for a week. It is strange, isn't it?

    New Jersey Middle School Makes Students Go Phone-Free

    A middle school in Union County, New Jersey, is forcing its students to stay disconnected in class, by prohibiting cellphones. Maxson Middle School Principal Kevin Stansbury put forward the phone ban last week after he noticed some major issues in the school. "Our test scores were down, discipline was up," he says. According to him, students were too focused on their phones to pay attention to their lessons. So, he purchased Yondr pouches for the school.

    Yondr pouch

    When students come into class each morning, they place their phones in the pouch, which is then locked up tight. It can only be opened using a special device at the end of the day. The ban on mobile devices applies not just during class time but during breaks, with the only exceptions being in times of emergency or in cases of students who need such devices to help with disabilities.

    Eighth-graders who spoke with News 12 New Jersey say that they noticed a change in a matter of hours. "It's just better for everyone because you'll understand how it feels to get more work done instead of paying attention to the phone," says student Charlene V. "I'm usually listening to music, but today I got to communicate with all my friends," says student Desiree Duncan.

    The program was originally met with resistance from students and parents, so the process was not that smooth. But teachers and administrators say that the program will have a major impact. "Students were talking and laughing and there were no cellphones other than being carried in the pouches," Stansbury says.

    Teacher Nia Cummings says she even noticed students bouncing ideas off each other in class. She says students used to give up quickly and just look for answers on their phones. She says they now try to figure it out themselves. "Everyone is socializing and eating lunch together. That's what I wasn't seeing enough of when phone usage was at its worst," she adds.

    Maxson Middle School is currently the only one in the district to use these pouches. Kevin Stansbury also called on all the schools in the community that it's worth paying close attention to cellphone issues at secondary schools and taking actions when necessary.

How do you kill your time on your way to work? Most of us stare at our cell phones, and refuse to make eye contact with others. We just read, chat with others online or play games online. Or maybe we're using the time between stops to do our makeup, catch up on emails, or read a few chapters of a book. However, Dina Alfasi takes a very different approach.

Each day she has to travel hours on buses and trains to get to her engineering job at a hospital in Israel. Rather than look at her cell phone in silence, she uses one very special way to have connection with strangers. It is portraits of the people she meets on public transport every day that she is taking. The paintings catch those quiet and personal moments of people readying themselves for the day ahead. Some people lean their head against the window and go to sleep, some stare into space and have a daydream, and others sit quietly to read their documents or books. Each picture catches one tiny moment in people's lives, ripe with potential for your imagination. It is wonderful for her to look at someone's commute (上下班) and make up an entire story about the rest of their daily existence, from the father travelling with a baby to the woman welcoming a change.

"What inspires me very much are the little moments that happen every day," Dina told My Modern Met. "My work is to tell stories through a single portrait, and it proves that all you need is just to look around and find those magic moments."
