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.

    Computers have beaten human world champions at chess and, earlier this year, the board game Go. So far, though, they have struggled at the card table. So we challenged one AI to a game.

Why is poker(扑克)so difficult? Chess and Go are “information complete” games where all players can see all the relevant information. In poker, other players' cards are hidden, making it an “information incomplete” game. Players have to guess opponents' hands from their actions—-tricky for computers. Poker has become a new benchmark for AI research. Solving poker could lead to many breakthroughs, from cyber security to driverless cars.

    Scientists believe it is only a matter of time before AI once again vanquishes humans, hence our human-machine match comes up in a game of Texas Hold's Em Limit Poker. The AI was developed by Johannes Heinrich, researcher studying machine learning at UCL. It combines two techniques: neural(神经的)networks and reinforcement learning(强化学习).

    Neural networks, to some degree, copy the structure of human brains: their processors are highly interconnected and work at the same time to solve problems. They are good at spotting patterns in huge amounts of data. Reinforcement learning is when a machine, given a task, carries it out, learning from mistakes it makes. In this case, it means playing poker against itself billions of times to get better.

    Mr Heinrich told Sky News: “Today we are presenting a new procedure that has learned in a different way, more similar to how humans learn. In particular, it is able to learn abstract patterns, represented by its neural network, which allow it to deal with new and unseen situations.”

    After two hours of quite defensive play, from the computer at least, we called it a draw.

    Weaving hammocks is an art that takes a sharp eye, a skilled hand and lots of patience. But in Lenwood Haddock's case, being blind works to his advantage. His trained, sensitive hands are acutely aware of every step of the process. Since beginning his craft in 1986, Lenwood has woven about 145, 000 perfect hammocks.

    Lenwood lost his sight in 1973, at age 18, during a hunting accident. “My whole working career has been blind,” he says. He first found a job as a woodworker, but when that organization closed, the North Carolina Division of Services for the Blind connected him with Hatteras Hammocks. On his first day of work. “I did a total of one hammock,” Lenwood recalls, laughing. “And then I came home and lay down to sleep. I lift weights, but I wasn't as tough as I thought until I started weaving.lt takes a lot of energy, and you're standing up all day.”

    In time, however, Lenwood found he had a knack (窍门) for the job. At first he worked on-site at the company, but after a year Lenwood moved his operation to the home workshop where he had worked for 10 years during his woodworking days.

    There, he creates dozens of hammocks each week from ropes in a variety of sizes. One day, he realized the step counter on his phone recorded him walking eight miles without ever leaving his shop.

    The process of weaving a hammock involves making and catching hundreds of loops (环). A single missed stitch (织针) creates a hole that can widen and make the hammock uncomfortable or even dangerous to use. Experienced weavers miss loops sometimes, but to his company's knowledge, Lenwood has never turned in a hammock with even one dropped stitch. Lenwood's skilled fingers are quick to catch and fix any mistakes.

    The company has acquired other brands and changed its name to The Hammock Source. Today, it is the world's largest maker and seller of hammocks, all built by hand.

    However, Lenwood's routine has changed little. He works his fingers back and forth across the rows, looping the rope and pulling it. With every hammock, Lenwood presents himself a perfect product. “I'm not sure how sighted people do it,” he admits.

    For most of her life, Suanne Laqueur's passion for storytelling was shown on the dance floor.

    Although Laqueur began writing at a young age, dancing always took center stage. She majored in dance and theater at Alfred University and taught at her mother's dance studio in Croton-on-Hudson, New York, for years. But when her mother was ready to retire and an opportunity opened for Laqueur to take over the studio, she realized she had no interest in taking on the business side of her art: "Owning a studio is a lot of work—financially, logistically. I love the teaching, the choreographing(编舞), the staging, but I didn't want to own it."

    Yet Laqueur's disinterest in running the studio changed when she became a self-published author. In the fall of 2013, she decided to pursue Self-publishing as a way of sharing her first completed novel with friends and family. During the process, she realized that following her true passion—telling stories through writing—made the business of the art worthwhile, and owning that business meant she could direct her writing career however she chose.

    Starting with her second self-published novel, she began investing more time in marketing and building her audience. Her investment paid off. Since 2014, Laqueur, now 49, has self-published six novels, which collectively have hundreds of ratings and reviews on Goodreads. Her 2016 novel An Exaltation of Larks stole the show at the 25th Annual Writer's Digest Self-Published Book Awards, topping more than 2,300 entries to win the grand prize.

    "You have to write the most truthful story to you, and I think self-publishing allows that freedom,' she says. "If you work with traditional publishing, it's more about what's marketable, There are trade-offs, which everyone will tell you, but by self-publishing I have control of the book, I have control of the story, and I'm cool with that."

A living robot has been created out of frog skin cells. Xenobots, named after the frog species Xenopus laevis that the cells come from, were first described last year. Now the team behind the robots has improved their design and demonstrated new capabilities.

To create the xenobots, Michael Levin at Tufts University in Massachusetts and his colleagues obtained tissue from 24-hour-old frog embryos after very small physical operation. Where the previous version relied on the contraction of heart muscle cells to move them forward by pushing off surfaces, these new xenobots swim around faster. They also live between three and seven days longer than their previous generation, which only lasted about seven days, and have the ability to sense their surroundings to some extent, turning red when exposed to blue light.

"The fundamental finding here is that when you free skin cells from their normal context, and you give them a chance to build other things than what they normally build," says Levin. "To me, one of the most exciting things here is that they are plastic. This idea that even normal cells, not genetically modified, are in fact capable of building something completely different."

Because they are created from cells, the xenobots eventually break apart and are totally biodegradable, says team member Douglas Blackiston, also at Tufts University. He therefore hopes that they can be used for biomedical and environmental applications.

Previous attempts at creating living robots, such as a wirelessly controlled cockroach, have involved dealing with live animals, raising ethical concerns. Xenobots differ from these because they are made entirely of living cells. "The approach here is maybe ethically the least problematic because everything starts with cells. They have no neurons, so it's not an animal," says Auke ljspeert at the Swiss Federal Institute of Technology at Lausanne, who wasn't involved in the research. "It's really cells, so I find it maybe the cleanest way."
