Jumping off random cliffs(悬崖) into the sea is not clever. However, as a sport, coasteering uses local experts to help groups travel around the coast so they can then jump safely and have a lot of fun in the process. But coasteering is also so much more than cliff jumping.

    A usual day's coasteering will involve swimming, climbing, scrambling(攀岩) and cliff jumping. All trips begin with a safety brief and equipment check. You will be equipped with a helmet, wetsuit and life vest. You will need to wear some old sneakers you don't mind getting wet.

    From here it could be a short swim to the first jump site. Following an instructor, you swim through rock pools, around rough rocks and right up to the next jump spot. A brief climb and you'll be standing on the edge wondering, “Why the hell did I agree to this?” Then, and to the yell of your friends, you're leaping in, with a smile that's guaranteed to last the rest of the day.

    Coasteering is certainly more than cliff jumping. If ever a sport could claim to be confidence building, this is it. And it's also a perfect activity for groups of friends or for adventurous families who want to explore the coast. Many companies offer daily trips, so even if you are on your own or a couple you can join in with a large group. Companies use trained guides with much knowledge of local tides and weather conditions. These people lead the show and are qualified lifesavers as well.

    Coasteering is already popular around the UK. At least now you won't have to ask “What is coasteering?” if someone you know gives it a go.

    How often do you let other people like a bad driver, a rude waiter, or an angry boss, change your mood?

    Sixteen years ago I learned a lesson. I got in a taxi, and we took off for Grand Central Station. We were driving in the right lane when all of a sudden, a black car jumped out of a parking space right in front of us. My taxi driver used his brakes, the tires made a loud noise, and at the very last moment our car stopped just 3cm from the back of the other car.

    I couldn't believe it. But then I couldn't believe what happened next. The driver of the other car, the guy who almost caused a big accident, turned his head around and he started shouting at us. I couldn't believe it!

    My taxi driver just smiled and waved at the guy. So, I said, “Why did you just do that? This guy could have killed us!” And this is when my taxi driver told me what I now call, “The Law of the Garbage Truck”. He said, “Many people are like garbage trucks. They run around full of garbage, full of anger and disappointment. As their garbage piles up, they look for a place to dump it. And if you let them, they'll dump it on you.”

    So I started thinking how often I let Garbage Trucks run right over me and how often I take their garbage and spread it to other people.

    I began to see Garbage Trucks. I see the load people are carrying. I see them coming to dump it. And like my taxi driver, I don't take it personally. I just smile, wave, wish them well, and move on.

    The Nazca Lines are a series of large ancient geoglyphs (地画) in the Nazca Desert, in southern Peru. It is ranging from geometric patterns to drawings of different animals and stylized human-like forms. The ancient lines can only be truly taken in from high in the air, leaving generations puzzled as to how these precise works could have been completed long before the documented invention of human flight.

    The Lines were first spotted when commercial airlines began flying across the Peruvian desert in the 1920,s. Who built them and what was their purpose? Are they roads, star pointers，maybe even a gigantic map? If the people who lived here 2,000 years ago had only a simple technology, how did they manage to construct such precise figures? Did they have a plan? These markings are like a vast puzzle.

    The Nazca Lines are the most outstanding group of geoglyphs in the world. There are also huge geoglyphs in Egypt, Malta，United States (Mississippi and California), Chile，Holivia and in other countries. But the Nazca geoglyphs, because of their numbers， characteristics, dimensions and cultural continuity as they were made and remade throughout a certain history period, form the most impressive archeological (考古学的) group.

    The Nazca plain is unique for its ability to preserve the markings upon it, due to the combination of the climate (one of the driest on Earth, with only twenty minutes of rainfall per year) and the flat, stony ground which minimizes the effect of the wind at ground level. With no dust or sand to cover the plain and little rain or wind to erode (腐蚀) it, lines drawn here tend to stay drawn. These factors, combined with the existence of lighter-colored subsoil beneath the desert surface, provide a vast writing pad that is suited to the artist who wants to leave his mark eternal.

    Judge Frank Caprio is a famous person in the city of Providence, Rhode Island. And, he is starting to get noticed around the world, too. He is an 80-year-old judge in the capital city of Rhode Island, the smallest state in the U. S.. One of his jobs is to take charge of traffic court. That involves talking to people who have gotten traffic tickets for going though red lights or parking illegally. They go to traffic court to question the tickets. Caprio hears what they have to say. Then, he decides whether or not the ticket is legal.

Caprio recently heard the case of a young man who was driving his mother's car. He went through a light after it turned red. After he spoke with the high school student, Caprio decided to let him off with a warning—if he promised to go to college and graduate.

    Another video from the Providence traffic court came out earlier this week. It showed a woman speaking with Judge Caprio about a parking ticket. She went to traffic court after getting a ticket for parking in an area that only permitted parking after 10 a. m. . The ticket was written at 9:59 a. m. . The woman said the clock in her car showed 10 a. m., so she thought it would be OK. After some conversation, the judge decided to dismiss the ticket.

    But Caprio did tell her, “You violated the city laws.” He held up a large book of rules. He smiled and the woman laughed. He said: “Our parking enforcement officers are second to none in the country!” After talking with the court officer, he said “I think 9:59 is close enough. Matter is dismissed.”

    The video was viewed over 1 million times in just two days. One person wrote of the video: “This is so cute. What a great judge. LOVE THIS.” Others wondered if the video was real, because it seemed so funny. But, there actually are judges out there like Frank Caprio. He is as real as they come.

Scientists at the Department of Energy's Lawrence Berkeley National Laboratory and the California Institute of Technology have-in just two years-nearly doubled the number of materials known to have potential for use in solar fuels.

They did so by developing a process that promises to speed the discovery of commercially viable (商业可行性) generation of solar fuels that could replace coal, oil, and other fossil fuels.

Solar fuels, a dream of clean-energy research, are created using only sunlight, water, and carbon dioxide. Researchers are exploring a range of possible target fuels, but one possibility is to produce hydrogen by splitting water.

Each water molecule (分子) consists of one oxygen atom and two hydrogen atoms. The hydrogen atoms are extracted, and then can be reunited to create highly flammable hydrogen gas or combined with CO 2 to create hydrocarbon fuels, creating a plentiful and renewable energy source. The problem, however, is that water molecules do not simply break down when sunlight shines on them-if they did, the oceans would not cover most of the planet. They need a little help from a solar-powered catalyst (催化剂).

To create practical solar fuels, scientists have been trying to develop low-cost and efficient materials that perform the necessary chemistry using only visible light as an energy source.

A new method was developed through a partnership between the Joint Center for Artificial Photosynthesis (JCAP) and Berkeley Lab's Materials Project, using resources at the Molecular Foundry and the National Energy Research Scientific Computing Center (NERSCC). JCAP focused on developing a cost-effective method of turning sunlight, water, and carbon dioxide into fuel. It is led by Caltech with Berkeley Lab as a major partner. The Materials Project is a program based at Berkeley Lab that aims to remove the guesswork from materials design in a variety of applications.

"What is particularly significant about this study, which combines experiment and theory, is that in addition to identifying several new compounds for solar fuel applications, we can also learn something new about the basic electronic structure of the materials themselves." says Neaton, the director of the Molecular Foundry.
