Watching a 3D movie can more than double the concentration powers and cognitive(认知) processing of children, a new research claims.

    A study made by visual technology firm RealD and led by child psychologist Dr. Richard Woolfson suggests that children aged between 7 and 14 experienced twice the cognitive processing speed and performed better in testing after watching 20 minutes of a 3D film. This is despite suggestions that attention spans(时期) in children have shortened in the last decade due to unlimited to access to entertainment, including on-demand TV, gaming and social media. A 2015 study claimed that watching 3D content had a similar effect to brain-training exercises.

    Consumer psychologist Mr. Fagan said that the increased stimulation(刺激) found in watching something in 3D "exercised" the brain and improved performance in the short term. "3D films can play the role of ‘brain-training' games and help to make children ‘smarter' in the short term," he said. "The shortening of response times after watching 3D was almost three times as big as that gained from watching 2D; in other words, 3D helps children process aspects of their environment more quickly. This is likely to be because 3D is a mentally stimulating experience which ‘gets the brain's juices flowing'."

    The experiment saw children given a range of cognitive tests before watching 20 minutes of a movie in either 2D or 3D and being tested again. The results showed those who saw the 3D content reacted faster and performed bettering the second round of testing. Mental engagement also rose by 13% among 3D watchers. Child psychologist Dr. Woolfson added that “supportive parenting” and regularly listening to classical music can also aid a child's memory.

    Denali National Park, Alaska

    History

    Within Denali National Park, the Toklat River will always have a special significance, as it was the location where naturalist Charles Sheldon built a cabin and was so moved that he fought to preserve the land. He moved back east and spent nine years lobbying (游说）to create Alaska's first national park.

    When to Visit

    To avoid the crowds, visit in June, but keep in mind that there are up to 21 hours of sunlight in Alaska in summer. If it seems like a bit much for your taste, try visiting in late August or September.

    If you visit to climb Mount McKinley, May and early June are the best times to climb.

    Major Attractions

    It is difficult not to see Denali's largest attraction towering 20,320 feet high. Mount McKinley can even be seen up to 70 miles away on a clear day. If you brave the climb to the top, you will be rewarded with charming views of the Alaska Range.

    Sable Pass is a prime spot to view grizzly bears. Closed to off-road foot traffic, the area is popular for bears feeding on berries, roots, and even occasionally on other mammals.

    Beginning at just below the summit of Mount McKinley, Muldrow Glacier flows 35 miles through a gorge and across the tundra. Twice in the last hundred years, the Muldrow has surged (涌动）, most recently in the winter of 1956-1957.

Accommodation

    Five campgrounds are located within the park, and many are open from late spring to early fall.Note: reservations are strongly recommended during summer. Riley Creek campground is open all year round, and all but two (Sanctuary and Wonder Lake) offer RV (可供居住的大篷车）sites.

    Also within the park are a few lodges (旅馆）—North Face Lodge, Denali Backcountry Lodge and Kentishna Roadhouse.

    A unique experience awaits you at the Centre for Alternative Technology on the edge of the beautiful Snowdonia National Park.

    Over thirty years ago a group of people decided to try out alternative technologies. They chose a remote empty place, where rock used to be dug from the ground, as their base. Here experiments offering solutions to the world's energy problems were carried out, and nowadays many of these ideas have become common practice. You can experience all these for yourself in just one day with us, and then take away what you have learned and put it into practice at home. Be assured it will help you save on your household energy costs!

    Your visit to us begins with a ride up a steep 60-metre hillside on a railway which is worked by using the weight of water. At the top of the mountain you will enjoy beautiful views to the distant coastline. Then interactive displays show the power of wind, water and sun, while showing you what can be done in an ordinary household to reduce your influence on the planet.

    There was no soil when the project was started, so we created our organic gardens using our own home-made soil. You can enjoy woodland walks or even notice spring flowers growing on the roofs of environmentally-friendly buildings.

    In 2006 we opened our new eco-adventure playground for children, and we also run workshops where they can make models and become inventors of the future by putting wind, water or solar power into their own designs.

    The Centre for Alternative Technology is open all year round and has good rail, road and cycle links. In fact we offer a 50% reduction on the admission price if you arrive by bicycle. There is wheelchair access for disabled visitors—telephone us in advance if you would like assistance.

    There are many programs for high school students today that help lonely teenagers deal with loneliness. However, loneliness is not only an issue for teens but also an important and rarely acknowledged one in the elderly.

    In Britain, Tracey Crouch was appointed to be the first Minister of Loneliness in order to address the issues caused by loneliness. This is the first time such a position has been created.

    In Britain, there are around 9 million people who say they are lonely frequently. In Germany, a study conducted by Ruhr University Bochum found that 20 percent of people over the age of 85 felt lonely, and 14 percent of those between age 45 and 65 felt socially lonely. In the United States, more than 25 percent of the population lives alone, more than 50 percent are unmarried.

    Loneliness is generally associated with heart disease, overweight, and anxiety. Additionally, the stress from loneliness can cause your cells to change on a molecular(分子)level that reduces its abilities to defend your body against diseases. In fact, doctors believe having feelings of loneliness is equivalent to smoking 15 cigarettes per day in regard to its effect on health!

    In Britain, the new Minister of Loneliness will help introduce government policies on the issue and fund a charity—an organization for helping people in need, to devote their efforts towards aiding loneliness. There are charities that link lonely seniors to high school students in order to give them a line of communication whenever they feel lonely!

    The possibilities for the new Minister of Loneliness are endless. For example, she can provide education services to household businesses so that they can identify lonely customers if they see one. Loneliness fits into the category of being a social issue that must be monitored by the entire community in order to help those in need. Therefore, government involvement in medical services and care for seniors and others is vital for happy seniors.

    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.
