How to Manage Your Phone's Data Use

    Smart phones give you access to a wealth of information and media, but most networks put a limit on the amount of data you can use each month. A typical phone contract includes a data allowance of between 500MB and 10GB per month. {#blank#}1{#/blank#} You see, your usage can mount up surprisingly quickly – watching a film on the phone is about 700MB in SD, an hour of streaming TV is around 500MB or 60-140MB for the same of radio, chatting on Skype for an hour is around 40MB. {#blank#}2{#/blank#}

    If possible, wait until you can connect to free Wi-Fi before using your phone's data features.

    When you are on the road, use your car's GPS, not your phone, to find the way. {#blank#}3{#/blank#} But maps are preloaded in a GPS, making this free to use.

    {#blank#}4{#/blank#} Many of these are funded by ads that pop up on your screen. Every ad has to download through your network, using up your data allowance.

    If you regularly need to use a lot of data on your phone, consider a data-compressing(压缩) app, such as Onavo(www.onavo.com). {#blank#}5{#/blank#} So you use less of your monthly allowance. You may have to subscribe to such compression services, so you'll need to weigh up whether it's worth the cost.

    Darek Fidyka, a 38-year-old Bulgarian, had been paralyzed (瘫痪的) from the chest down for four years after a knife attack. Scientists from Britain and Poland took cells from his nose, transplanted (移植) them into his back and re-grew his spinal cord (脊髓). Now he can walk and even drive a car. The doctors were delighted but said it was the first step in a long journey.

    The breakthrough came after 40 years of research by Professor Geoff Raisman, who found that cells had the possibility to repair damage to nasal (鼻腔的) nerves, the only part of the nervous system that constantly re-grows. “The idea was to take something from an area where the nervous system can repair itself and put it into an area that doesn't repair itself,” Professor Raisman said.

    Polish doctors injected (注射) the nasal cells into Mr Fidyka's spinal cord above the injury and used some nerves from his ankle to form a bridge across the damaged tissue. The nasal cells appear to have caused the spinal nerves to repair themselves.

    Professor Raisman achieved this with rats in the late 1990's, but this is his greatest success. “I think the moment of discovery for me was Christmas in 1997 when I first saw a rat, which couldn't control its hand, put its hand out to me. That was an exciting moment, because I realized then that my belief that the nervous system could be repaired was true.”

    Doctors chose the easiest case for their first attempt—it might not work for others. But there is a real sense of hope that an idea once thought impossible has been realized.

    David Nicholls, who helped provide money for the breakthrough, said information about the breakthrough would be made available to researchers across the globe.

    “What you've got to understand is that for three million paralyzed people in the world today, the world looks a totally brighter place than it did yesterday,” he said.

    Do you intend to study at an American university? It takes a long time to get accepted at most American schools, perhaps as much as a year. That's why you should start choosing a school as soon as possible. It's a good idea to apply to several different institutions, so that you'll have a better chance of acceptance at one. You should start looking for information now, because the more information you have about each college, the better choice you can make.

    There are two good ways to get information you need. One is a general reference (参考) book, called Guide to American Colleges and Universities. The other good source of information is the catalogue (目录) published by each school.

    You can study the general guide in almost any American library. This book has many useful statistics, such as the number of students, the average test scores for people accepted to the school, the number of books in the library, and the number of teachers. You can also find the address of each school in this book.

    Although the general guidebook has helpful information, some of the facts may be out-of-date. For example, many schools raise their tuition every year. Since you'll need to know what your education will cost, out-of-date information will not be good enough. Also, schools sometimes change their requirements for entrance. To be sure that you are getting present information, write to the university and ask for its catalogue. The catalogue has more detailed information. For example, the catalogue can tell you if there is a special foreign student advisor, what kind of courses are offered, and what kind of housing is available. Some universities have dormitories, but at others you have to find your own place to live.

    With all of this information, you should be able to pick out several good schools.

    Many of us have reached in our pockets, feeling a vibration (振动), wrongly believing our mobile phones have just rung. The phenomenon even has a name: phantom (幻觉的) vibration syndrome—and found it is surprisingly common.

    Now scientists believe that we are so alert (警觉) for phone calls and messages we are misinterpreting slight muscle spasms (痉挛)as proof of a call. Robert Rosenberger, an assistant professor at the Georgia Tech Institute of Technology has studied the delusional calls. He said sufferers describe a vague tingling feeling which they think is their mobile phone indicating it has received a text message or call while on 'silent'. But when the device is retrieved, there was no one on the other end.

    Dr. Rosenberger said he found so many people say, "This happens to me, but I thought I was the only one. I thought I was odd." It seems that the syndrome particularly affects people at the beck and call of mobile phones or pagers. A 2010 study by Michael Rothberg and colleagues found that nearly 70 per cent of doctors at a hospital in Massachusetts suffered phantom vibrations. A more recent study of US college students found the figure was as high as 90 per cent.

    While the odd feeling is widespread, it does not seem to be considered a grave problem. Dr. Rosenberger said: "It's not actually a syndrome in a technical sense. That's just the name that's got stuck to it." He added," Only 2 per cent of people consider it a problem."

    While this phenomenon is widespread, the scientific community has not yet invested much effort in getting to the bottom of why we suffer phantom calls.

    Dr. Rosenberger said: "People are guessing it has something to do with nervous energy. The cognitive(认知的)scientists are talking about brain chemistry, cognitive pathways changing. But it's not like they have brain scans to go on." He said: "We have a phone call in our pocket all the time and it becomes sort of an extension of ourselves. We have this sort of readiness to experience a call. We feel something and we think, OK, that could be a call."

    Nobel prize winners sometimes display as much uniqueness when deciding how to spend their prize money as they did on the work that won them the award in the first place.

    When Sir Paul Nurse won the Nobel Prize for Medicine in 2001, he decided to upgrade his motorbike. A fellow winner in 1993, Richard Roberts, installed a croquet lawn in front of his house. Austrian author Elfriede Jelinek, who won in 2004, said the prize meant "financial independence."

    Lars Heikensten, executive director of the Nobel Foundation, said there were no obvious shopping trends among winners.

    "I think it depends a lot on which country they come from, their personal finances... what kind of incomes they have when they get the prize," he said.

    Real estate, however, is a popular option, at least among those willing to reveal what they spend the money on. Phillip Sharp, the American co-winner of the 1993 medicine prize, decided to splash out on a 100-year-old Federal style house. "I took that money and bought a little bit bigger house... It's a beautiful old place," he told AFP(法新社), adding that "The money is a nice part of the process", but "the important thing about the prize is the recognition."

    For winners of the peace prize the decision is often more clear-cut, as the honor tends to go to politicians, organizations and activists who are under more public supervision. Many, like US President Barack Obama in 2009 and the European Union in 2012, donate to charities.

    Literature winners tend to be more private about how they use the money, but the choice is often equally straightforward. "Even if Nobel-winning authors are quite well known, many of them will not have made much money from writing," said Anna Gunder, a Nobel literature expert at Uppsala University. While the prize might keep the wolf from the door for some years, giving them freedom to write, it can also briefly have the opposite effect. "It really changes their careers… During the first year after they've won they often write less, but they generally continue after a year or two," said Gunder.

 Chongqing heat sparks highest health alert

The Chongqing Health Commission and Chongqing Meteorological Observatory upgraded the city's second-level alert {#blank#}1{#/blank#}(issue) on Wednesday for heatstroke, changing to a first-level alert for heatstroke on Friday. It is the city's first such top-level alert.

According {#blank#}2{#/blank#} the chief forecaster of the municipal meteorological observatory, Luo Juan, the city's first-level alert for heatstroke must come after temperatures in at least eight districts and {#blank#}3{#/blank#}(county) rise above 40 C for five consecutive days.

From July 29 to Aug 12, a dozen districts in Chongqing had temperatures exceeding 40 C for five to 11 consecutive days. The heat wave is expected {#blank#}4{#/blank#}(continue) the following week.
