Their cheery song brightens many a winter's day. But robins are in danger of wearing themselves out by singing too much. Robins are singing all night一as well as during the day, British-based researchers say.

    David Dominoni, of Glasgow University, said that light from street lamps, takeaway signs and homes is affecting the birds' biological clocks, leading to them being wide awake when they should be asleep.

    Dr Dominoni, who is putting cameras inside nesting boxes to track sleeping patterns, said lack of sleep could put the birds' health at risk. His study shows that when robins are exposed to light at night in the lab, it leads to some genes being active at the wrong time of day. And the more birds are exposed to light, the more active they are at night.

    He told people at a conference, "There have been a couple of studies suggesting they are increasing their song output at night and during the day they are still singing. Singing is a costly behaviour and it takes energy. So by increasing their song output, there might be some costs of energy."

    And it is not just robins that are being kept awake by artificial light. Blackbirds and seagulls are also being more nocturnal. Dr Dominoni said, "In Glasgow where I live, gulls are a serious problem. I have people coming to me saying `You are the bird expert. Can you help us kill these gulls?'.During the breeding(繁殖)season, between April and June, they are very active at night and very noisy and people can't sleep."

    Although Dr Dominoni has only studied light pollution, other research concluded that robins living in noisy cities have started to sing at night to make themselves heard over loud noise.

    However, some birds thrive(兴旺)in noisy environments. A study from California Polytechnic University found more hummingbirds in areas with heavy industrial machinery. It is thought that they are capitalising on their predators(天敌)fleeing to quieter areas.

    The Queen has had to say goodbye to one of her longtime companions, her beloved pet corgi Holly, who has sadly passed away aged 13. The corgi will probably be familiar to royal fans who would recognize her from the 2012 London Olympics opening video.

    The dog was suffering from old age and was put down at Balmoral after suffering from an illness, leaving Her Majesty three surviving pet dogs, Willow and two corgi-dachshund crosses, Vulcan and Candy.

    According to a spokesperson for Buckingham palace, the Queen was deeply upset by Holly's passing and she doesn't like seeing her dogs suffer. Holly had attained a very good age. She gets more unsettled if they suffer and she knows that putting a dog down is often the kindest solution. She was devoted to Holly and wherever the Queen was, the dog was never far behind.

    Holly was included in one of the portraits for the Queen's 90th birthday, along with her other three pet dogs. Although the Queen usually has several pet corgis, it was recently revealed that she is keen not to breed（繁殖）any more of the dogs. Monty Roberts, a horse trainer who has previously given advice to Queen, told the Daily Mail, “She wouldn't leave any young dogs behind if she died. She wanted to put an end to it. Her Majesty had previously named one of her dogs after her friend, but the dog died in 2012. Dogs love for less time than human beings and we know we're going to lose them—but they are part of the Queen's family. She'll be quite upset.”

    One of the newest words on the coffee stage is “shade grown coffee”. Shade grown coffee isn't new. In fact, until only a few years ago, shade grown coffee represented the major coffee beans sold on the world coffee market. The coffee plant is a natural shade lover, growing best in the shade afforded by an overgrowing canopy (树冠) of rain forest plants. That canopy protects the coffee plant from sunlight that reduces its production and kills it.

    Shade grown coffee is, however, more expensive to grow, at least in the short run. Growing coffee in the shade means that coffee growers also have to spend time working on the protectors. It means that less land is left to produce coffee beans. The arrival of technically engineered coffee plants that grow well in the sun represented a major development in coffee industry. Because there was no need to grow shade trees to protect the coffee trees, farmers could use more and more land to grow coffee trees, increasing their productivity and leading to more money for the coffee plantations (种植园) and farmers.

    However, it was not a good idea to move away from shade grown coffee. The sheltering canopy provided more than just shade for the coffee trees. Those plants provided shelter for birds and other animals who feed on pests.

    They help to fix nitrogen in the soil, and nitrogen is a natural fertilizer which makes plants grow more successfully. The increase in land used to grow sun loving coffee trees also had an unexpected effect on the law of supply and demand. The increased production resulted in a huge amount of coffee beans coming to the market, which brought down prices.

Moreover, most experts agree that shade grown coffee is better in taste than coffee grown in full sun. Plants grown in shade take longer to develop. The slower growing time helps to improve the coffee's taste. You can buy a can of shade grown coffee to replace your usual sun coffee. One cup of coffee a day—it's a small price to pay for a better world.

    Are you so sure your mistakes are just mistakes? Or could they be building blocks to a success beyond any you imagined?

    When my friend Dorothy goes home to visit her family each Thanksgiving, her mother serves the traditional “mistake salad”. The dish was born many years ago, Dorothy explains, when mother was using a cookbook to make a salad. In the process, by mistake, mother included half the salad ingredients (原料) from a recipe (食谱) on the left side of the open cookbook, and half the ingredients from a different salad recipe on the opposite page. Everyone enjoyed the salad so much that she continued to serve it every year. So it was really not a mistake at all.

    Then there was the man named Alfred, who invented dynamite (炸药). When Alfred's brother died, the city newspaper mistook his brother for him, saying in the news that the dead's most famous act was the creation of bombs (炸弹). Surprised to consider that his name would forever be connected with destruction, Alfred wanted to leave a more positive impression on people. So he set a prize for people who made contributions to world peace. Now the Nobel Prize, set up by Alfred Nobel, is the most respected prize in the world.

    Everything is part of something bigger, and so are mistakes. In his brilliant book Illusions, Richard Bach explains that every problem comes to you with a gift. If you only fix your attention on what went wrong, you miss the gift. If you are willing to look deeper and ask for the bright, the problem will disappear. You are left only with the learning, and you go forward on your path.

Singapore's public transport system is one of the best in the world, so you should have no problem finding your way around like a local. There are three main forms of public transport that you would find in any major city here — trains, buses and taxis.

    For car rental, call Avis at +65 6737 1668.

    Most heroes are not super. They don't appear in comic books, on television, or in movies. They just do what they believe needs to be done to make their world a better place. Bike Batman is one of them.

    Bike Batman is a 30 - year – old married engineer who lives in Seattle, Washington. He's a cyclist who also buys and sells bikes as a hobby.

    About three year, ago, he was looking for his wife. He found one on Craigslist, a website where people list things they want so sell. As he often does, he also looked at Bike Index, a popular website that allows users to register their bikes and post reports when they're taken. The bike, which he was considering purchasing, clearly matched one reported stolen on? Bike Index. Then he called the person who claimed to be the bike's owner and arranged to meet him－supposedly to complete the sale. When the two men met, Bike Batman told the thief. You've got two option. You can wait until a police officer gets here, or you can just get out of here." You can imagine what the thief did.

    After that first success, Bike Batman developed a safer routine. When he sees questionable bike ads on Craigslist, he cross-references the image with bikes reported on Bike Index. Once he has confirmed it with the owner, he arranges a meet - up with the thief and will call the Seattle police department so that officers can participate in the action. In more than half of the 22 cases in which he has got back and returned bikes y the thieves have been arrested. In one case, Bike Batman even helped a family recover a wide range of prized possessions that suspects had stolen during a home burglary.

    His nickname came from a discussion with a police officer who suggested he be called "Robin Hood". Since he wasn't exactly stealing from the rich and giving to the poor, "Batman" seemed a better fit. The idea of a superhero punishing criminals feels pretty silly to him, but the main reason he continues his work is to keep up Seattle's reputation as a friendly city.
