Often a nickname is a shortened form of a person's name, and it can also be a descriptive name for a place or a thing. Many American cities have nicknames. These can help build up an identity, spread pride among citizens and build their unity. Nicknames can also be funny.

    Los Angeles, California is the second largest city in population, after New York City. Los Angeles has several nicknames. One is simply the city's initials, L.A. It is also called the City of Angels because Los Angeles means "the angels" in Spanish.

    Los Angeles often has warm, sunny weather. So another nickname is City of Flowers and Sunshine. New York is called The Big Apple. So Los Angeles is sometimes called The Big Orange because of the fruit that grows in that city's warm climate.

    The American movie and television industries are based in Los Angeles. So it is not surprising that it is called The Entertainment Capital of the World. Many films are made in the area of Los Angeles called Hollywood. Millions of people visit the area. No trip to Los Angeles is perfect without seeing the word "Hollywood" spelled out in huge letters on a hillside.

    Many movie stars live in Los Angeles. The city is sometimes called Tinseltown. This nickname comes from the shiny, bright and often unreal nature of Hollywood and the movie industry.

    Another nickname for Los Angeles is La-La Land, using the first letters of Los and Angeles. This means a place that is fun and not serious, and maybe even out of touch with reality.

    A good place for watching unusual-looking people is Venice, an area on the west side of Los Angeles. A system of waterways designed after the Italian city of Venice has been built there. Many people love Los Angeles for its warm sunny weather, beautiful mountains and beaches, and movie stars. That includes Randy Newman, who sings about his hometown.

    On the whole, Los Angeles is growing attractive just for its rich nicknames.

    Babies made from three people approved in UK

Babies made from two women and one man have been approved by the UK's fertility regulator. The historic and controversial move is to prevent children being born with deadly genetic diseases.

    Doctors in Newcastle - who developed the advanced form of In Vitro Fertilization or IVF (人工授精) - are expected to be the first to offer the procedure and have already appealed for donor eggs. The first such child could be born, at the earliest, by the end of 2017.

    Some families have lost multiple children to incurable mitochondrial (线粒体的) diseases, which can leave people with insufficient energy to keep their heart beating.

The diseases are passed down from only the mother so a technique using a donor egg as well as the mother's egg and father's sperm has been developed.

    The resulting child has a tiny amount of their DNA from the donor, but the procedure is legal and reviews say it is ethical (伦理的) and scientifically ready.

    "It is a decision of historic importance," said Sally Cheshire, chairwoman of the Human Fertilisation and Embryology Authority (HFEA)."I'm sure patients will be really pleased by what we've decided today."

    But some scientists have questioned the ethics of the technique, saying it could open the door to genetically-modified(转基因) 'designer' babies.

    The HFEA must approve every clinic and every patient before the procedure can take place. Three-person babies have been allowed only in cases where the risk of a child developing mitochondrial disease is very high.

    Prof Mary Herbert, from the Newcastle Fertility Centre, said: "It is enormously pleasing that our many years of research in this area can finally be applied to help families affected by these devastating diseases.

    "Now that that we are moving forward towards clinical treatments, we will also need donors to donate eggs for use in treatment to prevent affected women transmitting disease to their children."

    Prof Sir Doug Turnbull, the director of the Wellcome Centre for Mitochondrial Research at Newcastle University, said: "We are delighted by today's decision. We will also provide long-term follow up of any children born."

    NHS England has agreed to fund the treatment costs of the first trial of three-person IVF for those women who meet the HFEA criteria, as long as they agree to long-term follow up of their children after they are born.

    When Randy Heiss went hiking behind his Patagonia, Ariz. farm, the last thing he expected to find was a Christmas list from a little girl across the US-Mexico border. "I found this balloon on my morning walk near Patagonia on Sunday. Attached to it was a piece of paper with the Christmas wishes from a little girl," Heiss wrote on his Facebook page.

    When he brought the list home to his wife, who speaks fluent Spanish, they determined that the little girl had asked for Enchantimals toys, clothes, art supplies and various other gifts. That's when Heiss set out to make the little girl's Christmas dreams come true. Heiss said he had attempted to send Christmas letters to Santa Claus via balloon when he was a kid but never received a response.

    Heiss sent a Facebook message on Wednesday to XENY, a radio station in Nogales, to see if it could help him track down the girl or her family. He later received a response from the station, which had determined the author of the letter was an 8-year-old girl named Dayami, and the station wanted to set up a meeting between the two on Thursday. "It just changed my entire day," Heiss told the Washington Post. "Instead of going back to my office in Bisbee, I went with my wife to Walmart."

    The couple bought almost everything on Dayami's list. They also brought a few gifts for Dayami's little sister, Ximena. They told the children they were " ayudantes de Santa," or Santa's helpers.

    Heiss, 60, said the experience was very healing for him and his wife. Nine years ago, the couple's only son died. "Being around children at Christmas time has been absent in our lives," Heiss said. We now have friends for life. For a day, that border fence with its concertina wire melted away.

    "Our aim is to take our art to the world and make people understand what it is to move," said David Belle, the founder of parkour.

    Do you love running? It is a good exercise, yet many people find it boring. But what if making your morning jog a creative one? Like jumping from walls and over gaps, and ground rolls? Just like James Bond in the movie Casino Royale? Bond jumps down from a roof to a windowsill and then runs several blocks over obstacles on the way. It is just because of Bond's wonderful performances that the sport has become popular worldwide.

    Yes, that's parkour, an extreme street sport aimed at moving from one point to another as quickly as possible, getting over all the barriers in the path using only the abilities of the human body. Parkour is considered an extreme sport. As its participants dash around a city, they may jump over fences, run up walls and even move from rooftop to rooftop.

    Parkour can be just as exciting and charming as it sounds, but its participants see parkour much more than that.

    Overcoming all the obstacles on the course and in life is part of the philosophy behind parkour. This is the same as life. You must determine your destination, go straight, jump over all the barriers as if in parkour and never fall back in your life, to reach the destination successfully. A parkour lover said, "I love parkour because its philosophy has become my life, my way to do everything."

    Another philosophy we've learnt from parkour is freedom. It can be done by anyone, at any time, anywhere in the world. It is a kind of expression of trust in yourself.
