    Scientists think that growing garden grass could be the secret to solving our energy needs, and we may soon be able to replace our gasoline with "grassoline".

    The team, including experts from Cardiff University in Wales, has shown that hydrogen can be taken from grass in useful amounts with the help of sunlight and a cheap catalyst(催化剂) —something that speeds up a chemical reaction without being used up.

    It is the first time that this has been shown and it could lead to a sustainable(可持续的) way of making hydrogen, reported Asian News International. This could be an important kind of renewable energy because it is high in energy and it does not give out harmful gases when it is burned.

    Study co-author Michael Bowker said, "This is really a green source of energy. Hydrogen is seen as an important future energy carrier as the world moves from fossil fuels to renewable energy, and our research has shown that even garden grass could be a good way of getting it."

    Cellulose(纤维素), which is a key part of plants and the biopolymer(生物聚合物) found in the largest numbers on the earth, could be a great source of hydrogen.

In its study, the team looked at the possibility of getting hydrogen from cellulose using sunlight and a simple catalyst.

    This is called photocatalysis(光催化作用) and in it, the sunlight starts the catalyst, which then makes cellulose and water into hydrogen. The researchers studied the effectiveness of three metal-based catalysts, of which nickel(镍) especially interested the researchers, as it is a much more common metal than gold and palladium(钯) and it saves more money.

    According to Bowker, producing hydrogen from cellulose using photocatalysis has not been studied in detail. The team's research shows that large amounts of hydrogen can be produced using this method with the help of a bit of sunlight and a cheap catalyst.

    The study shows that it is effective to use real grass taken from a garden. "This is important as it avoids the need to separate and clean up cellulose, which can be both difficult and costly," said Bowker.

    Rainy days don't have to get you down, a happiness expert has reported.

    Paul Dolan, Professor of Behavioral Science at the London School of Economics, said that people only feel miserable in bad weather because they think about it too much. Studies have shown that people who live in warm, sunny climates are no happier than those in chilly, wet climates, he says. So the British talking about the weather may be making us gloomier(沮丧的) than the weather itself.

    He said: “A study was done that measured the happiness levels of people in California compared to the North West. “They expected that people in California would be happier because it is more sunny, but they found that levels of happiness were exactly the same. If it is sunny every day you get used to it and the sunshine doesn't make you any happier. Most of the time the weather doesn't influence our well-being at all. But when we think about it, and think that it does, that's when we get miserable.”

    In his new book, Happiness By Design, Dolan argues that we can think ourselves happy by taking our attention away from what makes us sad.

    “Most of our anxieties come from what might be,” he argues. “If you want to be happier, pay attention to the things that make you feel good.”

    He also claimed that a problem shared was not always a problem halved(减半). He believed that humans are actually very good at being able to get over tragedy(悲剧) and loss.

    Professor Dolan also admitted for the first time that he had a stammer(口吃), which had made his early life miserable. He added it only got better when he learned not to pay attention to his speech problem.

    “Things are never as bad as you imagine them being,” he said.

    I've been in the taxicab business for thirty-five years, and I know there is a lot about it that is not so good. Taxicab drivers have to be tough fellows to be able to work in New York. You've got to fight the New York traffic eight hours a day these days, so people get the wrong impression that they are bad.

    Actually, taxi drivers are just like other people. Most of them will behave as honest fellows. You read in the papers almost every week that a taxi driver turns in money or jewels that people leave in their cabs. If they weren't honest, you wouldn't be reading those stories in the papers.

    One time in Brooklyn, I found a diamond ring in my cab. I remembered helping a lady with a lot of packages that day, so I went back to where I had dropped her. It took me almost two days to trace her down in order to return her ring to her. I didn't get as much as “thank you”. Still I felt good because I had done what was right. I think I felt better than she did.

    I was born and raised in Ireland and lived there until I was nineteen years old. Then I came to this country where I had a family and bought my own cab. Life hasn't been too easy at times, but my wife takes care of our money and we have a good bit put away for a rainy day.

    When I started driving a cab, Park Avenue was mostly a bunch of coal yards. Hoofer's Brewery was right next to where the Waldorf-Astoria is now. I did pretty well, even in those days. In all my years of driving a taxicab, I have never had any trouble with the public, not even with drunks.

    I believe honesty is one of the greatest gifts. I know they call it a lot of fancy names these days, like integrity(正直), etc. But it doesn't make any difference what they call it; it's still what makes a man a good citizen. This is my code, and I try to live by.

Visit tfl.gov.uk/tube for more information.

    Tip:

    Always stand on the right when using the escalators (电动扶梯) at Tube stations. It can get hot and busy on the Tube during peak (高峰) travel times, so you may prefer to travel outside these hours.

    Buses

    A cheap and easy way to travel around London. They generally run from 05:00 to 00:30. Night buses operate on many major routes from around midnight to 05:00, and some operate a 24-hour service.

    It is not possible to pay for your London bus fare in cash. Instead you can pay with a Visitor Oyster card, Oyster card, Travelcard or UK-issued contactless payment card. A single bus journey is £1.50 with an Oyster card or UK-issued contactless payment card.

    To help you get home, if you don't have enough credit on your Oyster card, you will be able to make one more bus journey.

    After this you will need to top up the credit on your card before you use it again. If your contactless payment card has been issued outside the UK, please check tfl.gov.uk/contactless before you use your card to travel on our bus services. For any international transaction fees (手续费) that may apply, please check with your card issuer.

    For more information visit tfl.gov.uk/buses.

    On November 14, 1902, President Theodore Roosevelt was on a hunting trip in Mississippi while trying to settle a line(边界) problem between Mississippi and Louisiana. Being an expert outdoorsman, he liked to hunt large animals.

    However, his hunt was going poorly that days, and he couldn't seem to find anything worthy of firing his gun. His followers, trying to help him, caught a Louisiana black baby bear for the President to shoot, but he refused. The thought of shooting a bear that was tied to a tree did not seem sporting, so he spared the life of the baby bear and set it free.

    A famous political cartoonist for the Washington Star, Mr. Clifford Berryman, drew a cartoon titled. Drawing the Line in Mississippi, which used the story of the President refusing to shoot the bear.

    The cartoon in the Washington Star showed Teddy Roosevelt, gun in hand, with his back turned on a pretty baby bear. Morris Michtom, owner of a Brooklyn toy store, got the idea from the cartoon and make a toy bear. Planning to use it only as a display, he placed the bear in his toy store window, and next to it placed a copy of the cartoon from the newspaper. To Michtom's surprise, he was surrounded by customers eager to buy it. He asked for and received President Roosevelt's permission to use his name for the bears that he and his wife made, and the Teddy Bear was born! Michtom soon made Teddy bears by the thousands. The money from selling Teddy bears made him, in 1903, form the Ideal Toy Company.
