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.”

    The morning had been a disaster. My tooth was aching. And I'd been in an argument with a friend. Her words still hurt: “The trouble with you is that you won't put yourself in my place. Can't you see things from my point of view?” I shook my head stubbornly—and felt the ache in my tooth. I'd thought I could hold out till my dentist came back from holiday, but the pain was really unbearable. I started calling the dentists in the phone book, but no one could see me immediately. Finally, at about lunchtime, I got lucky.

    “If you come by right now,” the receptionist said, “the dentist will fit you in.”

    I took my purse and keys and rushed to my car. But suddenly I began to doubt about the dentist. What kind of dentist would be so eager to treat someone at such short notice? Why wasn't he as busy as the others?

In the dentist's office, I sat down and looked around. I saw nothing but the bare walls and I became even more worried. The assistant noticed my nervousness and placed her warm hand over my ice-cold one.

When I told her my fears, she laughed and said, “Don't worry. The dentist is very good.”

    “How long do I have to wait for him?” I asked impatiently.

    “Come on, he is coming. Just lie down and relax. And enjoy the artwork,” the assistant said.

    “The artwork?” I was puzzled.

    The chair went back. Suddenly I smiled. There was a beautiful picture, right where I could enjoy it: on the ceiling. How considerate the dentist was! At that moment, I began to understand what my friend meant by her words.

What a relief!

    The Things Successful People Do Differently

    Why have you been so successful in reaching some of your goals, but not others? If you aren't sure, you are far from alone in your confusion. It turns out that even brilliant, highly accomplished people are pretty lousy when it comes to understanding why they succeed or fail. The intuitive(直觉的) answer--that you are born with certain talents and lacking in others--is really just one small piece of the puzzle. In fact, decades of research on achievement suggests that successful people reach their goals not simply because of who they are, but more often because of what they do.

    1）Get specific.

    When you set yourself a goal, try to be as specific as possible. “Lose 5 pounds” is a better goal than “lose some weight,” because it gives you a clear idea of what success looks like. Knowing exactly what you want to achieve keeps you motivated until you get there. Also, think about the specific actions that need to be taken to reach your goal. Just promising you'll “eat less” or “sleep more” is too vague--be clear and precise. “I'll be in bed by 10pm on weeknights” leaves no room for doubt about what you need to do, and whether or not you've actually done it.

    2）Seize the moment to act on your goals.

    To seize the moment, decide in advance when and where you will take each action you want to take. Again, be as specific as possible (e.g., “If it's Monday, Wednesday, or Friday, I'll work out for 30 minutes before work.”) Studies show that this kind of planning will help your brain to detect and seize the opportunity when it arises, increasing your chances of success by roughly 300%.

    3）Know exactly how far you have left to go.

     Achieving any goal also requires honest and regular monitoring of your progress--if not by others, then by you yourself. If you don't know how well you are doing, you can't adjust your behavior or your strategies accordingly. Check your progress frequently--weekly, or even daily, depending on the goal.

    The softshell turtle species is officially listed as endangered by the IUCN Red List. Scientists long thought softshell turtles were extinct in the Cambodian part of the Mekong River until they discovered some stragglers (掉队者) in the early 2000s.

    The species had quite a wide historical range across Asia, but much of that range is now completely gone. Much of the turtle's habitat in Southeast Asia have disappeared due to urban and industrial development along the Mekong River. The sand where turtles multiply is routinely carried away for use in construction projects, while fishing nets lift up hatchlings. People also take turtles and their eggs to sell for food.

    Initial surveys in 2003 and in 2007 found two small populations of the softshell turtles along a 30-mile stretch (水域) of the Mekong River. Since then, conservation groups have worked with local communities and officials to increase the wild population of these endangered turtles, including a program to hire former egg collectors to help search for and protect nests instead of harvesting the eggs.

    For the last decade, WCS, Conservation International, the Turtle Survival Alliance and local groups have worked to protect turtle nests. Their goal is to ensure eggs will multiply and hatch, and that baby turtles grow strong enough to eventually take care of themselves in the wild.

    A team recently released 150 hatchlings back into their natural habitat, bringing the total to more than 7,700 baby turtles in the past 10 years.

Most people assume that the human brain is set on "automatic"—that means it learns all by itself. But this isn't always true. We need to train ourselves to be better learners—to actively take part in the learning process and to reflect on what we have learnt. These kinds of learning behaviours are called "active learning". I suggest doing four things to take an active role in your learning.

Listen to the outer voice

There are two kinds of voices: the inner voice and the outer voice. Your inner voice expresses your personal opinions, while the outer voice tells you about opinions from what you hear or read. Although your inner voice can be useful, it can also get in the way of learning. If you keep paying too much attention to it, you risk missing important information. Instead, active learners are open-minded and focus on what the speaker/ write is saying, not on what their brain is saying in the background. In this way, they are in a better position to make decisions.

Ask questions

Asking questions is the easiest way to promote active learning. When you get information from someone, from books or the Internet, ask two, three, even five question about the topic. The answers will lead you to further learning, and the very act of working out questions will help you to achieve a higher level of understanding about the topic. In short: Do not stop being curious.

Get to the truth

Active learners do not accept everything they learn. They attempt to find the truth at the heart of each idea. Even when an idea sounds entirely unlikely, there may be an aspect of it that is based on truth. So if someone says that dinosaurs still exist today, think about why they believe this. Where does the idea come from? Do they have enough data to support their views? If you try to find out the source of an idea, no matter how crazy it seems, you will increase your chance of learning something.

Focus on the message

Many people miss out on learning opportunities because they let their feelings get in the way. They refuse to learn or ignore what is said because of who the speaker/ writer is. It is true that we cannot help disliking some people —this is human nature, after all. But do not forget you can still learn from them. Active learners do not judge people based on firs impressions or personal feelings. Instead, they separate the message from the message. This goes the other way as well—do not just assume that some people are always right because of who they are or just because they are your friends.
