Having experienced a shocking electrical accident, which caused him to become both blind and deaf, James Franco's world became completely dark and quiet for almost ten years. The loss of sight and hearing threw him into such sorrow that he tried a few times to put an end to his life. His family, especially his wife, did their best to tend and comfort him and finally he regained the will to live.

    One hot summer afternoon, he was taking a walk with a stick near his house when a thunderstorm started all at once. He stood under a large tree to avoid getting wet, but he was struck by the lightning. Witnesses thought he was dead but he woke up 20 minutes later, lying face down in muddy water. He was trembling badly, but when he opened his eyes, he could hardly believe what he saw: a tree and a muddy road. When Mrs. Franco came running up to him, shouting to their neighbors to call for help, he could see her and hear her voice for the first time in nearly ten years.

    The news of James regaining his sight and hearing quickly spread and many doctors came to examine him. Most of them said that he regained his sight and hearing from the shock he got from the lightning. However, none of them could give a compellent answer as to why this should happen. The only reasonable explanation given by one doctor was that, since James lost his sight and hearing as a result of a sudden shock, perhaps, the only way for him to regain them was by another sudden shock.

Jennifer Fish, a weather forecaster may soon be replaced by something truly fishier—the shark.

    Research by a British biology student suggests that sharks could be used to predict storms.

    Laura Smith, 24, is close to completing her study on shark's ability to sense pressure.

    If her studies prove the theory, scientists may be able to monitor the behaviour of sharks to predict bad weather.

    Miss Smith had previously studied the behaviour of lemon sharks in the Bahamas.

    She then used their close relatives, lesser spotted dogfish (猫鲨), for further research at Aberdeen University.

Her work—thought to be the first of its kind to test the pressure theory—resulted from the observation that juvenile blacktip sharks off Florida moved into deeper water ahead of a violent storm in 2001.

    Miss Smith said: “I've always been crazy about traveling and diving and this led me to an interest in sharks.”

“I was delighted to have been able to research in the area for my degree. I know there's so much more we need to understand—but it certainly opens the way to more research.”

    It has been discovered that a shark senses pressure using hair cells in its balance system.

    At the Bimini Shark Lab in the Bahamas, Miss Smith fixed hi-tech sensors to sharks to record pressure and temperature, while also tracking them using GPS (Global Positioning System) technology.

In Aberdeen, she was able to study the effects of tidal (潮汐的) and temperature changes on dogfish—none of which were harmed. She also used a special lab which can mimic (模拟) oceanic pressure changes caused by weather fronts.

    She is due to complete her study and graduate later this year. She says she will be looking for a job which will give her the chance to enrich her experience of shark research.

    Last April, on a Sunday, we took one of our “nowhere” drives. My husband was quietly driving along a back road. I was occupied in the front passenger seat watching the scenery.

    I noticed out of the corner of my eye that my husband was struggling to look out of my window. This frightened me, since his eyes should be on the road in front of him. I asked him what he was looking at out of the windows, and he quietly replied, “Nothing.”

    After a few minutes, I looked over at my husband and noticed a tear running down his cheek. I asked him what was wrong. This time he told me, “I was just thinking about Pop and a story he had once told me.” It had something to do with Pop, his friend from childhood, and I wanted to know the story, so I asked him to share it with me.

    He said, “When I was 8 years old, Pop and I were out fishing and he told me that the pine trees know when it is Easter.”

    I have no idea what he meant by that, so I pressed him for more information.

    He continued on… “The pine trees start their new growth in the weeks before Easter because spring is drawing near. If you look at the tops of the pine trees, you will see the yellow shoots. As the days get closer to Easter Sunday, the tallest shoot will branch off and form a cross. By the time Easter Sunday comes around, you will see that most of the pine trees will have small yellow crosses on all of the tallest shoots.”

    I turned to look out of the window and I couldn't believe my eyes. It was a week before Easter, and you could see all of the trees with the tall yellow shoots stretching to the sky.

    The tallest ones shone in the sunlight like rows of tiny golden crosses. May you find your Easter season filled with beautiful golden crosses!

    For the brave in the army, being sent away from home is just part of the duty. However, it's never easy especially for those with children. So, when I found out I was going to stay in South Korea for a year, I was nervous about how my five children, particularly my eldest daughter Abigail, would take the news since it meant I wouldn't be home to see her graduate from high school.

    To my surprise, Abigail told me not to worry and even suggested we make the news known among family members. "We've been lucky you haven't had to be sent abroad yet. Anyway, we can get connected through the Internet. See me on your phone." Abigail said. She stepped into many of my roles when I was gone. I wanted to find a way to thank her and show her how proud I was of her. I started planning the special surprise when my request to return home a few weeks earlier to attend Abigail's graduation ceremony(典礼) was approved.

    When my time in South Korea finally came to an end, I flew home, and stayed in a hotel. On Abigail's graduation day, I hid in an office behind the stage waiting until I heard her name called. I just kept thinking "Don't cry. Don't trip in your heels. Don't fall over." At last! Abigail was up on stage. I slipped up behind her, whispered in her ear, and around she turned! "I was just thinking, like, 'You aren't supposed to be here. What? What? How?' It was the biggest shock... I'm pretty sure my dad made people he didn't even know cry. Emotional for everyone." Abigail cried.

    You know what followed: embraces, kisses, tears, laughs, flowers, wishes...; aren't they what a family have in store?

    Anyone watching the autumn sky knows that migrating birds fly in a V formation, but scientists have long debated why. A new study finds that these big－winged birds carefully position their wingtips and flap(拍动) at the same rate, probably to catch the upward movement of air and save energy during flight.

    There are two reasons birds might fly in a V formation: It may make flight easier, or they're simply following the leader. Squadrons(中 队) of planes can save fuel by flying in a V formation, and many scientists suspect that migrating birds do the same. Models that treated flapping birds like fixed－wing airplanes show that they probably save energy by drafting off each other, but currents created by airplanes are far more stable than those coming off of birds.

    Just as aerodynamic(气动力) calculations would predict, the birds positioned themselves to fly just behind and to the side of the bird in front, timing their wing flaps to catch the uplifting eddies(涡流). When a bird flew directly behind another, the timing of the flapping reversed(相反) so that it could minimize the effects of the downdraft coming off the back of the bird's body. “We didn't think this was possible,” Usherwood says, considering that the difficult achievement requires careful flight and incredible awareness of one's neighbors. “Perhaps these big V formation birds can be thought of quite like an airplane with wings that go up and down.”

    The findings likely apply to other long－winged birds, such as pelicans and geese, Usherwood says. Smaller birds create more complex wakes(尾波) that would make drafting too difficult. The researchers did not attempt to calculate the birds' energy savings because the necessary physiological measurements would be too invasive for an endangered species. Previous studies show that birds can use 20% to 30% less energy while flying in a V.

    Scientists do not know how the birds find that aerodynamic sweet spot, but they suspect that the animals line themselves up either by sight or by sensing air currents through their feathers. In future studies, the researchers will switch to more common birds, such as pigeons or geese. They plan to investigate how the animals decide who sets the course and the pace, and whether a mistake made by the leader can ripple through the rest of the flock to cause traffic jams.

    Which kind of diamond is better for the environment and the world we live in: a diamond from a traditional mine or one made in a laboratory?

    Some recent reports suggest the answer may not be so clear. At the very least, these reports provide evidence of tensions between two different sectors of the diamond industry.

    Lab -grown diamond companies say they are more ethical and cause less harm to Earth's environment. The traditional diamond sector notes that its businesses help the communities where they operate mines. It says they provide jobs, help build roads and other infrastructure and make investments in conservation.

    Some companies, such as De Beers, work on both sides. De Beers sells natural and man-made diamonds. In the United States, the Federal Trade Commission(FTC) investigates reports of deceptive, or misleading, advertising. In April, the commission sent warning letters to eight lab-grown diamond companies. One of the FTC's concerns was the use of the word 'eco-friendly', and similar terms, to describe diamonds made in a laboratory. The lab-grown process requires very high temperatures and uses a lot of energy. Trucost is a company that estimates the costs of using natural resources. Asked by the Diamond Producers Association to study the issue, Trucost found the carbon intensity of natural diamonds was lower than lab-grown diamonds.

    The Trucost report did note that diamond miners should reduce their effect on the environment by using more renewable energy, such as wind power and sunlight.
