Several safari camps operate as the base for this adventure, providing unique rides twice a day to explore deep into the delta. The camps have excellent horses, professional guides and lots of support workers. They have a reputation for providing a great riding experience.

              The morning ride, when the guides take you to beautiful, shallow lakes full of water lilies, tends to be more active. It is unlike any other riding experience. With rainbows forming in the splashing water around you and the sound of huge drops of water bouncing off your body and face. It is truly exciting. You are very likely to come across large wild animals, too. On horseback it is possible to get quite close to elephants, giraffes and many other animals. The sense of excitement and tension levels rise suddenly though, as does your heart rate, as you move closer to them.

              In the evening, rides are usually at a more relaxed and unhurried pace. With golden light streaming across the grassy delta and the animals coming out to eat and drink. Sedate though they are, rides at this time of day are still very impressive. As the sun's rays pass through the dust kicked up by the horses, the romance of Africa comes to life.

              Back at the camp you can kick off your boots and enjoy excellent food and wine. Looking back on your day, you will find it hard to deny that a horseback Safari is as close as you will ever come to answering the call of the wild.

    Most people know precious gemstones (宝石) by their appearances. An emerald flashes deep green, a ruby seems to hold a red fire inside, and a diamond shines like a star. It's more difficult to tell where the gem was mined, since a diamond from Australia or Arkansas may appear the same to one from the Democratic Republic of the Congo. However, recently, a team of scientists has found a way to identify a gemstone's origin.

    Beneath the surface of a gemstone, on the tiny level of atoms and molecules（分子）, lie clues (线索) to its origin. At this year's meeting of the Geological Society of America in Minneapolis, Catherine McManus reported on a technique that uses lasers (激光) to clarify these clues and identify a stone's homeland. McManus directs scientific research at Materialytics, in Killeen, Texas. The company is developing the technique. “With enough data, we could identify which country, which mining place, even the individual mine a gemstone comes from,” McManus told Science News.

    Some gemstones, including many diamonds, come from war-torn countries. Sales of those “blood minerals” may encourage violent civil wars where innocent people are injured or killed. In an effort to reduce the trade in blood minerals, the U.S. government passed law in July 2010 that requires companies that sell gemstones to determine the origins of their stones.

    To figure out where gemstones come from, McManus and her team focus a powerful laser on a small sample of the gemstone. The technique is called laser-induced breakdown spectroscopy. Just as heat can turn ice into water or water into steam, energy from the laser changes the state of matter of the stone. The laser changes a miniscule part of the gemstone into plasma, a gas state of matter in which tiny particles（微粒）called electrons separate from atoms.

    The plasma, which is superhot, produces a light pattern. (The science of analyzing this kind of light pattern is called spectroscopy.) Different elements produce different patterns, but McManus and her team say that gemstones from the same area produce similar patterns. Materialytics has already collected patterns from thousands of gemstones, including more than 200 from diamonds. They can compare the light pattern from an unknown gemstone to patterns they do know and look for a match. The light pattern acts like a signature, telling the researchers the origin of the gemstone.

    In a small test, the laser technique correctly identified the origins of 95 out of every 100 diamonds. For gemstones like emeralds and rubies, the technique proved successful for 98 out of every 100 stones. The scientists need to collect and analyze more samples, including those from war-torn countries, before the tool is ready for commercial use.

    Scientists like Barbara Dutrow, a mineralogist from Louisiana State University in Baton Rouge, find the technique exciting. “This is a basic new tool that could provide a better fingerprint of a material from a particular locality,” she told Science News.

    A drunken burglar（盗贼） in the Orrell Park area of Liverpool, ended up leaping out of a window after a 10-year-old girl asked him to prove he was a superhero.

    The drunken thief who pretended he was Superman to stop a child raising the alarm has been caught after he leapt from the apartment building in his pants to make the girl convinced.

    Thief Ethan Adamson, 25, told police that he had broken into a fifth-floor flat after a drinking session, believing it was empty.

    But he was horrified when the owner's 10-year-old daughter woke up while he was there.

    From his hospital bed, the thief told reporters, “To keep her quiet, I told her I was really Superman and I'd soon be flying off back to my secret headquarters.”

    “She called my bluff (吓唬) and told me, 'If you're Superman, show me you can fly or I'll scream'.

    “I had no choice so I stripped to my pants to look more like a superhero and went to the window. I saw another roof below and I thought I could make it but it turned out to be a lot further down than thought. I know it doesn't make sense but it did to me when I was drunk.”

    Police later found him on the roof in just his yellow pants, covered in cuts and bruises after a baffled neighbor heard his cries of pain.

    He now faces seven years behind bars for burglary.

    Police spokesman Frank Amado said, “He was in quite a serious state and couldn't move until we got up there using ladders. He was treated for his injuries and we got him some fresh clothes, before taking him to hospital where he is being kept under guard until he is well enough to be arrested.”

    Michael Jackson was on the road of performing when he was five years old. As is known to all, the road to fame and fortune is a long, hard one.

    Michael remembers those early years when he was young." My father was a machine operator," he explained, "and he worked at a steel plant. My mother worked at Sears, a big department store. But they were both musicians."

    Michael's father Joe Jackson realized his sons had a lot of talent, and he knew he could train them to become fine musicians. In those days there were plenty of music groups and some of them were very good. He knew if his sons were to stand out, they would have to be the best.

    Practice makes perfect. And the Jackson boys practised! Gradually the group took shape. Then word of this group began to get around. Thus Michael got a chance to do some solo(独唱) songs. In the following years, Michael was always on the top. One million records of his were sold in New Zealand, which has only a total population of three million!

    When Michael was eighteen, he entered another field of his career(生涯)—acting. "I plan to star in movies," he told his friends, "but of course, my first love is music."

    Michael wrote a lot of his own songs. "Songs came about in the strangest ways," he said, "I'll just wake up from sleeping and there is a whole song coming into my head. And then I put it down on the paper."

    Still, with all his success, Michael managed to keep his head calm. "I just do a different job from other people," he said, "but it doesn't make me think I'm better than other people."

    To be quite honest, his fans just love to hear and watch him!

    A humpback, a kind of big whale, can weigh as much as 40 tons and reach 50 feet from nose to tail. That means they can easily overturn small boats and it can be a great trouble to anyone who jumps on the back of the animal.

    But that was just what Sam Synstelien did when he saw a humpback in trouble in Central California's Morro Bay. The animal was hopelessly tangled (缠绕) in a rope that was attached to a buoy (浮标).

    Synstelien, along with his partner Nicholas Taron, had already tried reporting the poor animal to the U. S. Coast Guard—but they were told it would be hours before rescuers could come. Hours, the fishermen thought, this whale didn't have. "If we wanted the humpback to survive we had to go to get it," Taron later said. "We thought there was no other choice for the whale; we decided to go for it. We were so excited then. I don't think we were that scared. "

    It's easy for Taron to say, of course. His role in the rescue was mostly in the cheering department. In the video, you can hear him shouting "Swim! Swim! Move! Just get it! Get it!" from the side of the boat while filming the entire rescue. "The humpback was just swimming in circles," Taron said. "You could tell it was stressed and being held to the bottom."

    The very agitated whale didn't take well to human intervention (介入) and even hit the boat with its huge tail with a lot of force. But Synstelien hung in there, and at last cut through the rope. And then with a sudden move, the humpback swam deep down beneath the waves. It wasn't much of a thank you, but Synstelien and Taron were happy.
