A world-famous Canadian author, Margaret Atwood, has created the world's first long-distance signing device(装置), the LongPen.

    After many tiring……from city to city, Atwood thought there must be a better way to do them . She hired some technical experts and started her own company in 2004. Together they designed the LongPen. Here's how it works: The author writes a personal message and signature on a computer tablet(手写板) using a special pen. On the receiving end, in another city, a robotic arm fitted with a regular pen signs the book. The author and fan can talk with each other via webcams(网络摄像机) and computer screens。

    Work on the LongPen began in Atwood's basement(地下室). At first, they had no idea it would be as hard as it turned out to be. The device went through several versions, including one that actually had smoke coming out of it. The investing finally completed, teat runs w ere made in Ottawa, and the LongPen was officially launched at the 2006 London Book Fair. From here , Atwood conducted two transatlantic book signings of her latest book for fans in Toronto and New York City.

    The LongPen produces a unique signature each time because it copies the movement of the author in real time. It has several other potential applications. It could increase credit card security and allow people to sign contracts from another province. The video exchange between signer and receiver can be recorded on DVD for proof when legal documents are used.

     “It's really fun”, said the owner of a bookstore, who was present for one of the test runs. “Obviously you can't shake hands with the author but there are chances for a connection that you don't get from a regular book signing..

    The response to the invention has not been all favorable. Atwood has received criticism from authors who think she is trying to end book tours. But she said, “It will be possible to go to places that you never got sent to before because the publishers couldn't  afford it.”

    Unbelievable Stories of Animals Acting Just Like Humans

    Horses are picky eaters

    Horses have an even better sense of smell than humans do. When horses raise their noses and open their nostrils (鼻孔) , their nervous system allows them to sense smells we can't sense. This might explain why they refuse dirty water and carefully mover around meadows, eating only the tastiest grasses, experts say.

    Whale says thanks

    In 2011, a whale expert spotted a humpback whale trapped in a fishing net and spent an hour freeing it. Afterward, in an hour-long display of thanks, the whale swam near their boat and leaped into the air about 40 times.

    Pandas like to be naughty

    Is there anything more lovely than a baby panda, except maybe a human baby? In fact, baby pandas sometimes behave like human babies. They sleep in the same positions and value their thumbs. Pandas are shy by nature for its shy behaviors such as covering its face with a paw of ducking its head when confronted by a stranger.

    A cat honors its owner

    Paper towels, and a plastic cup are just a few of the gifts that Toldo, a devoted three-year-old gray-and-white cat, has placed on his former owner Iozzelli Renzo's grave every day since the man died in September 2011. Renzo adopted Toldo from a shelter when the cat was three months old, and the two formed an inseparable bond. After Renzo passed away. Toldo followed the coffin to the cemetery, and now “stands guard” at the grave for hours at a time.

    If you are worried about the planet, please make sure your rubbish is buried under the ground.

    People talk about "reduce, reuse, recycle." It sounds like a good idea. There is a problem, though. Recycling costs too much money.

    Even the U.S. Environmental Protection Agency (EPA) says it only makes sense economically and environmentally to recycle about 35 percent of disabled (废弃的) materials. Among those materials are paper and aluminum(铝) cans. Recycling 1 ton of paper or aluminum cans, the agency says, can save about 3 tons of CO₂ emissions (排放物) over producing those materials anew. Paper producers pay for the trees they process. If it was cost-effective to recycle paper, producers would be beating down your door to buy it. But they aren't. That means it's more expensive to recycle old paper than to cut trees and then replant trees for processing.

    Plastic can be recycled too. Given the recent drop in crude oil (原油) prices, it is now cheaper to make a new plastic container than to recycle an old one. Even if that were not true, the EPA says that recycling a ton of plastic saves only about a ton of CO₂. However, it doesn't take into account the water most consumers use to wash their plastic containers before having them recycled. The New York Times journalist John Tierney recently wrote, "If you wash plastic in water that was heated by electricity, then the effort of your recycling could be more carbon in the atmosphere."

    Glass is another recyclable material. To reduce greenhouse gas emissions by 1 ton you have to recycle 3 tons of glass. If one includes the cost of collecting glass waste from neighborhoods, and the pollution produced by the collection trucks and the recycling process itself, glass recycling creates more greenhouse gas emissions and is more expensive than making new glass, which comes primarily from sand that exists everywhere.

    If recycling were truly cost-effective, private companies would be lining up at your doorstep to buy your rubbish. Don't look now because they're not there.

Planning a visit to the UK? Here we help with ways to cut your costs. 

AVOID BIG EVENTS Big sporting events, concerts and exhibitions can increase the cost of accommodation and make it harder to find a room. A standard double room at the Thistle Brighton on the final Friday of the Brighton Comedy Festival （19 Oct. ） cost £ 169. 15 at Booking. com. A week later, the same room cost £ 118. 15.

If you can be flexible and want to know dates to avoid or you're looking for a big event to pass your time-check out sites such as Whatsonwhen.com, which allow you to search for events in the UK by city, date and category. 

STAYAWAY FROM THE STATION If traveling to your destination by train, you -may want to find a good base close to the station, but you could end up paying more for the sake of convenience at the start of your holiday. 

Don't be too choosy about the part of town you stay in. Booking two months in advance, the cheapest room at Travelodge's Central Euston hotel in London for Saturday 22 September was £ 95. 95. A room just a tube journey away at its Covent Garden hotel was £ 75. 75. And at Farringdon, a double room cost just £ 62. 95.

LOOK AFTER YOURSELF Really central hotels in cities such as London, Edinburgh and Cardiff can cost a fortune, especially at weekends and during big events. As an alternative consider checking into a self-catering flat with its own kitchen. Often these flats are hidden away on the top floors of city centre buildings. A great example is the historic O'Neill Flat on Edinburgh's Royal Mile, available for £ 420 for five days in late September, with room for four adults. 

GET ON A BIKE London's "Boris bikes' have attracted the most attention, but other cities also have similar programmes that let you rent a bicycle and explore at your own pace, saving you. on public transport or car parking costs. 

Among the smaller cities with their own programmes are Newcastle （casual members pay around £ 1. 50 for two hours） and Cardiff （free for up to 30 minutes, or £ 5 per day）. 

For the past 60 years,the African Wildlife Foundation (AWF) has protected animals,restored lost habitats and advocated for policy changes that benefit wildlife.Now,the conservation organization is trying a new approach.

This year,AWF launched the inaugural Benjamin Mkapa African Wildlife Photography Awards.The contest aims to reach a different audience.While photography competitions are nothing new,AWF hopes that the exhibition of winning entries will encourage African people to take a more active role in conservation.Its CEO Kaddu Sebunya said,"Africans need to take responsibility for the conservation of their heritage."

Photographers of all ages and backgrounds,professional and amateur,were invited to submit to the competition.A judging panel,comprised of photographers,conservationists,activists and safari guides,selected photos from 12 categories including "Art in Nature" "Coexistence and Conflict" and "Conservation Heroes".

 The "Conservation Heroes" category had special appeal for Kenyan conservation photographer Anthony Ochieng Onyango."I realized there was a communication gap because most of what was being communicated was data in scientific publications," said Onyango,adding that images are a simple way for people to connect to complex issues.

While there were many entries in the AWF competition,there's only one 19-year-old Cathan Moore from South Africa among the category winners.There's a lack of opportunity for young aspiring photographers on the continent.AWF is seeking grants and partnerships to enable more African people to participate next year,and to make nature photography competitions more accessible to those unable to pay or buy expensive camera equipment,allowing people to use whatever camera they have and photograph wildlife in urban environments.

Sebunya hopes that the competition can open up a dialogue about conservation and why it's so important for Africa's future.Many people in Africa look at conservation as a thing done by and for foreigners,said Sebunya.While he praised the work of international NGOs,he emphasized that it's vital that African voices are heard and for local people to lead conservation efforts.

For many students who desire to move around but not far freely, one of the most common vehicles is the bicycle. For such a seemingly simple invention, its story is not that simple.

Most historians trace its origin back to 1817, when a German nobleman named Karl von Drais invented a wooden, two-wheeled machine that riders moved forward with their feet. His invention became popular in both England and France, where it eventually became known as the velocipede. Unfortunately, it was eventually banned as a danger to pedestrians and was rarely seen after the early 1820s.

Things were quiet for several decades until the bicycle development took off in the 1860s. An important milestone happened in Paris in 1863 when pedals (踏板) were added to the front axle (轴) . This occurred in Pierre Michaux's workshop but it's unclear whether he or his employee, Pierre Lallement, should be given credit for the innovation. Lallement moved to the United States, where he obtained a patent for "improvements in velocipedes" in 1866. These new machines proved to be popular, and the name "bicycle" had come into use by 1869. However, many people referred to them as "bone shakers", which described their clunky ride due to a heavy wooden frame and steel wheels.

In the 1870s, "high wheelers" or "penny-farthings" became popular. However, with a large front wheel and a much smaller rear wheel, they could be dangerous, if riders had to stop suddenly, as they would "take a header" when their momentum (动量) carried them over the front wheel onto their heads. Eventually, English inventor John Kemp Starley designed a "safety bicycle" with two same small wheels, a chain drive, and a set of gears. With tires added in and brake (刹车) systems bettered in the following decades, bicycle production had skyrocketed to over one million bicycles by 1899.

Mass production of bicycles increased their popularity greatly, since they became affordable for the average person. Over the course of the 20th century, manufacturers continued to improve the features and design of bicycles as new technologies appeared.
