“This way, everyone.” said the young Bahamian as he led the way to the boat. As the boat moved over the waves, I thought back eleven years to my first island visit via a cruise ship. As we landed, I noticed a sign advertising swimming with dolphins. I looked at my mother; she knew exactly what I wanted, but I was too young. “Maybe some other time,” she said. I think everyone knows that those four words usually translate to never. It made me, a little boy, depressed for many days. From that day on, it was my dream to swim with those gentle creatures.

    Now, after 15 minutes of travelling, we reached the Sanctuary Bay. As we arrived, I saw the gray creatures showing off their unique talent before my eyes. We were led off the boat, past a back building. Our guide told us we would have the pleasure of spending the next 90 minutes with Kaholo, a young male, and Robola, the largest female, who is quite famous for having played the lead in the film Zeus and Roxanne.

    My father and I were joined by four others and followed the man once more. He told us to jump into the water while he let the dolphins into that part of the bay. For the first 20 minutes, we could go anywhere and touch the dolphins as they swam by.

    Kaholo and Robola must have known I was their biggest fan because they swam towards me as if I had had fish. After the introductory period, they jumped over our heads. I got a hug and kiss from Robola, and also learned how to have Kaholo talk to me.

    This was by far the most magical experience of my life. Next time your parents say “Maybe some other day”, have faith in them. Your dreams are important to them too, and they will do whatever they can to make it possible, because dreams can come true.

    Crown shyness(树冠羞避) is a mysterious natural phenomenon in which the crowns of some tree species do not touch each other, but get separated by a gap clearly visible from ground level. The effect usually occurs between trees of the same species, but has also been observed between trees of different species.

    There are many theories going around, most of which make sense, but no one has been able to prove without the shadow of a doubt why some trees avoid touching each other.

    In his 1955 book Growth Habits of the Eucalypts, Australian forester M.R. Jacobs writes that the growing tips of the trees are sensitive to abrasion(擦伤), which results in crown shyness phenomenon. This theory was also supported by Dr. Miguel Franco. Some experiments have shown that if trees displaying crown shyness are artificially prevented from swinging in the wind and touching each other, they gradually fill up the gaps between them.

    But while the above theory is arguably the most widespread, it's certainly not the only one. Some scientists have suggested that crown shyness is a mechanism to stop the spreading of leaf-eating insects. These pests have been known to work together and create structures that extend up to 10 cm off of tree branches in order to reach other plants, so the gaps are the trees' natural defense method.

    One Malaysian scholar studied many trees, but found no traces of abrasions, despite their clear crown shyness. Instead, he suggests that the growing tips of the trees were sensitive to light levels and stopped growing when they got too close to other trees. Plants are able to sense how close they are to other plants and in order to get more light, they give off some chemical element to stop other trees from growing too close.

    Whatever the reason, one thing is for sure: plants are more intelligent than people used to think.

    The Great Depression that followed the stock market crash of 1929 saw hundreds of thousands of Americans out of work. In the years of great fear and depression, a lot of American citizens looked desperately to the federal government for assistance. Of all the programs designed by President Roosevelt when he took office in 1932, few were more criticized - or had more lasting impact - than the Work Projects Administration, better known as the WPA.

    The intention of the WPA, which functioned from 1935 to 1943, was to design and administer public works projects to help relieve unemployment. The majority of these projects involved historic or artistic attempts. The WPA's Writers Project, for example, was responsible not only for such practical works as state guidebooks but also for the collection of historically valuable oral histories. Over 2,900 of these records were collected in 24 states. They provide an irreplaceable firsthand account of people's diets, customs, celebrations, and political and religious beliefs at the time.

    The artworks created through the Federal Arts Project are one of the WPA's most lasting achievements. Out - of - work painters, both famous and unknown, created paintings that beautified schools, libraries, and government buildings, WPA photographers traveled across the country recording the hardships of life on small rural farms. When the United States entered World War Ⅱ in 1941, WPA artists were enlisted to produce posters supporting the war effort. Many WPA artworks, including hundreds of small drawings picturing scenes of everyday life, still exist today.

    One day, on a small farm in Maine, a man sat in a barn watching a large grey spider spin a web. The man was E.B. White — or Andy, as he was called — who thought spiders were wonderful creatures. He thought that one day he might like to write a children's book about a spider.

    But writing was hard work for Andy. He had written many articles and essays and poems. He had also written one children's book, Stuart Little. But Andy could never just rush to turn an idea into an article or a book. He told his editor (编辑) that he needed to let his ideas ripen.

    So for years, Andy continued to think about writing a children's book about a spider. He did some of his best thinking while he wandered around his farm.

    Once while he was cleaning his barn, he found a spider's egg sac (卵囊). Andy wanted to see the eggs hatch. But he was scheduled to leave for a trip to New York City. So he found a small box and carefully placed the egg sacinside. When he got to his hotel, he put the box on the dresser. One morning he woke up, and there were hundreds of baby spiders rushing across the dresser!

    Years later, Andy finally began writing Charlotte's Web, the story of a spider named Charlotte and a pig named Wilbur. Andy created most of the book sitting by himself in the tiny boathouse of his farm.

    Sometimes he stopped writing and aimlessly drew pictures of spiders. Andy always said Charlotte's Web was more than just a children's story about animals. It was a timeless story about true friendship.

    In our annual Readers' Choice Awards survey, we asked our readers to rate their favorite cities in the world for arts and culture. These cities are centers of music and dance, museums, and theaters. Here are four of them where you can find inspiration in the arts, starting with the top spot.

    Rome, Italy

    At its peak, the Roman Empire extended over nearly two million square miles of land across Europe, Asia Minor and North Africa. Today, that history is on display everywhere. The city's main attractions are famous not because of tourist advertisements, but because they are really so impressive. No wonder it's known as the Eternal City: You could spend forever here and find new artistic and cultural treasures every day.

    Paris, France

    Hemingway famously called Paris "a moveable feast", but wherever you go while in the city, there is always something to see, hear, taste or feel. With some 150 museums, Paris doubles as an art history class, offering the very best of the discipline across centuries and styles.

    London, United Kingdom

    London is inspiration and setting for the rise of Shakespeare, Dickens, Orwell and Eliot and the breeding ground for all those iconic (标志性的) bands: The Kinks, The Clash and The Stones. London is also Banksy's favorite canvas, home to more than 1,000 galleries, and the kind of place where you can spend a whole day in a single museum and still be ready for more when it opens the next morning.

    Vienna, Austria

    As we all know, Western music would be unrecognizable without Austria's capital, which nurtured many famous musicians. It's also the site of the Vienna Secession, a revolutionary art movement founded in 1897 by Gustav Klimt. Visitors today can see the fruits of all that creativity in the city's 100 – odd museums.

As part of our mission to inspire the next generation of scientists, inventors and engineers, the Science Museum Group (SMG) has launched an exciting new online game—Total Darkness.

Over the last year we have been developing Total Darkness with the aim of creating an experience that can have a positive impact on people's attitudes towards STEM (science, technology, engineering and maths), as well as having a focus on self-reflection, rather than asking players to recall specific facts or concepts.

Total Darkness is a digital storytelling experience which encourages young people to recognise how the skills they use every day relate to STEM and can help them develop their confidence in science thinking. The game invites the player to solve a mysterious power cut in their hometown. The game puts players in control, allowing their choices and decisions to guide them through the story.

As the player navigates through the darkened streets of the town, equipped only with a torch, they will face various challenges. Using their curiosity, communication skills and creative problem solving, they will discover new theories about what might have caused the blackout(停电；断电). But with every step their torch fades, and the player must solve the mystery before the battery runs out.

The player's choices and actions throughout the game will score them curiosity, creativity or communication points. At the end, the skills the player has used will be revealed along with their science style, showing how they could put their skills into action in the real world.

Total Darkness is aimed at 8-15 year-olds—an important stage in teens' science development. Research shows that as teens make the step between primary and secondary, many move away from an interest in science as other influences have a stronger pull in their lives.

Total Darkness is a free online game playable on smartphone, tablet and desktop. Play now at totaldarkness.sciencemuseum.org.uk.
