You can't always predict a heavy rain or remember your umbrella. But designer Mikhail Belyaev doesn't think that forgetting to check the weather forecast before heading out should result in you getting wet. That's why he created lampbrella, a lamp post with its own rain- sensing umbrella.

    The designer says he come up with the idea after watching people get wet on streets in Russia. “once, I was driving on a central Saint Petersburg street and saw the street lamps lighting up people trying to hide from the rain. I thought it would be appropriate to have a canopy (伞蓬) built into a street lamp.” he said.

    The lampbrella is a standard-looking street lamp fitted with an umbrella canopy. It has a built-in electric motor which can open or close the umbrella on demand. Sensors (传感器) then ensure that the umbrella offers pedestrians shelter whenever it starts raining.

In addition to the rain sensor, there's also a 360° motion sensor on the fiberglass street lamp which detects whether anyone is using the lampbrella. After three minutes of not being used the canopy is closed.

     According to the designer, the lampbrella would move at a relatively low speed, so as not to cause harm to the pedestrians. Besides, it would be grounded to protect from possible lighting strike. Each lampbrella would offer enough shelter for several people. Being installed (安装) at 2 meters off the ground, it would only be a danger for the tallest of pedestrians.

      While there are no plans to take lampbrella into production, Belyaev says he recently introduced his creation to one Moscow Department, and insists his creation could be installed on any street where a lot of people walk but there are no canopies to provide shelter.

    Planning a visit to the UK? Here were 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.

    STAY AWAY 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).

    The popular smartphone application Instagram (照片分享) has changed the way we look at photography, even our world. The photo-worthy moments we share serve as an important function in cultivating the photographic artistic eye.

    Instagram has got people to start noticing the art in their everyday life. It has also allowed us to share the artful moments in our lives with others. Clearly, making people focus on beautiful moments in their lives and how to share them is a positive takeaway from Instagram.

    Not only has Instagram changed the way we look at things around us, but it has also changed the way people view professional photography. Instagram has turned everyone with a smartphone into an artist. Opening up art to the general community is a groundbreaking (创新的) aspect of this application. Making artistic attempts accessible for everyone to discover their artistic talents and explore creatively is something that has made people find the beauty in the everyday. However, this accessibility has also created questioning around art and respect deserved by professional photography.

    The art in a professional photograph versus an Instagram can sometimes be hard to notice at a quick glance. But photographs taken by true professional photographers hold something that Instagram's can't match in terms of photographic quality, or advanced compositional knowledge.

    This is not to say Instagram is a lesser art. Aesthetic qualities of art are a personal matter and how good an artwork is depends on personal preferences. Good is a very arbitrary term in the art world. For example, I may find one photo more pleasing than another, but not everyone has to agree with me.

    The point I am trying to make is that professional photography should not be lost, but instead approached with a new, enhanced level of respect and admiration—despite how accessible, common and fun Instagram now makes the taking and sharing of photos.

    Why do some people live to be older than others? You know the standard explanations: keeping a moderate diet, engaging in regular exercise, etc. But what effect does your personality have on your longevity(长寿)? Do some kinds of personalities lead to longer lives? A new study in the Journal of the American Geriatrics Society looked at this question by examining the personality characteristics of 246 children of people who had lived to be at least 100.

    The study shows that those living the longest are more outgoing, more active and less neurotic (神经质的) than other people. Long-living women are also more likely to be sympathetic and cooperative than women with a normal life span. These findings are in agreement with what you would expect from the evolutionary theory: those who like to make friends and help others can gather enough resources to make it through tough times.

    Interestingly, however, other characteristics that you might consider advantageous had no impact on whether study participants were likely to live longer. Those who were more self-disciplined, for instance, were no more likely to live to be very old. Also, being open to new ideas had no relationship to long life, which might explain all those bad-tempered old people who are fixed in their ways.

    Whether you can successfully change your personality as an adult is the subject of a longstanding psychological debate. But the new paper suggests that if you want long life, you should strive to be as outgoing as possible.

    Unfortunately, another recent study shows that your mother's personality may also help determine your longevity. That study looked at nearly 28,000 Norwegian mothers and found that those moms who were more anxious, depressed and angry were more likely to feed their kids unhealthy diets. Patterns of childhood eating can be hard to break when we're adults, which may mean that kids of depressed moms end up dying younger.

    Personality isn't destiny, and everyone knows that individuals can learn to change. But both studies show that long life isn't just a matter of your physical health but of your mental health.

    The fiddler crab (蟹) is a living clock. It indicates the time of day by the colour of its skin, which is dark by day and pale by night. The crabs changing colour follows a regular twenty-four hour plan that exactly matches the daily rhythm (节奏) of the sun.

    Does the crab actually keep time, or does its skin simply answer to the sun's rays, changing colour according to the amount of light strikes it? To find out, biologists kept crabs in a dark room for two months. Even without daylight, the crab's skin colour continued to change exactly on time.

    This characteristic(特性) probably developed gradually in answer to the daily rising and setting of the sun, to help protect the crab from sunlight and enemies. After millions of years it has become completely regulated (受控制) inside the living body of the crab.

    The biologists noticed that once each day the colour of the fiddler crab is especially dark, and that each day this happens fifty minutes later than on the day before. From this they discovered that each crab follows not only the rhythm of the sun but also that of the tides (潮水). The crabs period of greatest darkening is exactly the time of low tide on the beach where it was cought!
