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.”

Murcia

    I have spent about 8 months living in Murcia and I feel that I should put it as number one on my list. On my return from exploring other cities, I always feel like I'm returning home when I set foot in Murcia. The city centre is full of life and energy and has an incredible atmosphere all year round. Although the accent takes you a little time to get used to at first, you will adjust to it. Murcia is also home to some gorgeous(壮丽的) beaches and amazing coastal views. So it really does have the best of both worlds!

Gibraltar

    I visited Gibraltar during the Easter holidays and I was totally surprised by the beauty of Gibraltar! From a short cable car riding up to the top of the rock you are met with splendid views over the coast and the adorable monkeys which curiously come to greet you on your arrival. Make sure to hide all your food because they think it's a gift for them!

Valencia

    Valencia is beautiful. It's as simple as that! The river-area is so exciting and full of life, all the way up to the science museum and beaches. However, I was a little confused by the fact that the river had long been filled in and turned into a park, yet people still referred to it as The River.

Alicante

    I have spent many a weekend in Alicante, making the most of the beautiful beach in low season, before all the tourists arrive. May is the high season here, so I'd definitely recommend a visit in April, September, or October, just before or after the holiday season.

    The Children's Book-Show Competition is a chance for young readers to be writers.

    Reading, it seems, is coming back in fashion, if a survey by the famous National Literacy Trust (the NLT) is true. It shows that the percentage of children who admit enjoying reading has grown for the first time in the past 8 years.

    So it's a good time to launch a competition that includes a shed-load of new books for schools as prizes. The Children's Book-show Competition, backed by The Independent, is taking to the roads again from the start of next term, with a nation-wide tour of 15 big cities, featuring a line-up of a dozen children's writers and illustrators (插图画家) aiming to persuade pupils to follow their footsteps.

    The competition, launched by the children's writer and illustrator Jessica Souhami, has two categories: the under-nine's and nine to 13-year-olds.

    Children are asked to choose their favorite fairy or folk tale and set it in an extraordinary place.

    Then they are to retell it with the aid of drawings and writings—whether it is set at sea, on a distant planet, in the future or in the past. The closing date for the competition is 30th November.

    “Tell your tale in pictures and in words, ”say the organizers of the competition. “It can be in a picture book or comic-book format.”

    The winner of each competition will receive a signed copy of a book by each of the 12 authors involved in this year's tour, plus £150 worth of books for their school. The runners-up will receive a signed copy of Souhami's new book.

    The New Caledonia Barrier Reef (新喀里多尼亚堡礁)is located in New Caledonia in the South Pacific, and is the second-longest coral reef in the world, after Australia's Great Barrier Reef. The New Caledonia Barrier reef surrounds Grand Terre, New Caledonia's largest island, as well as the Ile des Pins and several smaller islands, reaching a length of 1, 500 km. The reef encloses(围住) in a lake of 24, 000 square kilometers, which has an average depth of 25 meters. The reefs lie up to 30 kilometers from the shore, but extend almost 200 km to the Entrecasteaux reefs in the northwest. This northwestern extension encloses the Belep Islands. Several natural passages open out to the ocean. The Boulari passage(通道), which leads to Noumea, the capital and chief port of New Caledonia, is noted for the Amedee lighthouse.

    The reef has great species diversity with a high level of endemism(动植物的特有分布), and is home to endangered dugongs, a kind of sea animal, and is an important nesting site for Green Sea Turtle.

    Most of the reefs are generally thought to be in good health. Some of the eastern reefs have been damaged by wastewater from nickel mining(镍开采)on Grand Terre. The waste from mining, agriculture, and grazing(放牧) has affected reefs near river mouths, which has been worsened by the destruction of mangrove forests, which help to keep wastes. Some reefs have been buried under several meters of wastes.

    In January 2002, the French government proposed(提议) listing New Caledonia's reefs as a UNESCO World Heritage Site. UNESCO listed New Caledonia Barrier Reef on the World Heritage List on 7 July 2008.

    We work with Cambridge County Council's Participation Team to create opportunities for young people to visit the University and learn more about it. The following events are scheduled for the 2019/2020 academic year.

    Superstar workshops

    12 engaging workshops are planned for young people aged 7 to 11. These half-day visits will be held throughout the year, at times when young people are not at school. If participants complete 8 of the 12 workshops, they will be awarded the nationally recognized Superstar Crest Award.

Please note, workshops will only run if we have a sufficient number of attendees (usually around 3+ participants).

    Explore University Days

    Explore University Days are for young people aged 12-15. Participants visit the University for two days and engage with a range of university-related workshops, and other fun activities.

Previous participants have engaged with the following:

    Visited the Sports Centre

    Took part in a Neuroscience workshop

    Enjoyed a two-course meal at a University College

    Dates will be confirmed in early December 2019, and a schedule for event will follow in the New Year.

    Events for post-16 students

    If you are studying for your post-16 qualifications and are considering applying for Cambridge or would like to find out more about a specific subject, the following events might be for you:

    University and College Open Days

    Subject Master classes

    Cambridge Science Festival
