Recordings of angry bees are enough to send big, tough African elephants running away, a new study says. Beehives (蜂窝)—either recorded or real—may even prevent elephants from damaging farmer's crops.

    In 2002, scientist Lucy King and her team found that elephants avoid certain trees with bees living in them. Today, Lucy wants to see if African honeybees might discourage elephants from eating crops. But before she asked farmer to go to the trouble of setting up beehives on their farms, she needed to find out if the bees would scare elephants away.

    Lucy found a wild beehive inside a tree in northern Kenya and set up a recorder. Then she threw a stone into the beehive, which burst into life. Lucy and her assistant hid in their car until the angry bees had calmed down. Next，Lucy searched out elephant families in Samburu National Reserve in northern Kenya and put a speaker in a tree close to each family.

    From a distance, Lucy switched on the pre-recorded sound of angry bees while at the same time recording the elephants with a video camera. Half the elephant groups left the area within ten seconds. Out of a total of 17 groups, only one group ignored the sound of the angry bees. Lucy reported that all the young elephants immediately ran to their mothers to hide under them. When Lucy played the sound of a waterfall (瀑布) instead of the angry bees to many of the same elephant families, the animals were undisturbed. Even after four minutes, most of the groups stayed in one place.

    Lucy is now studying whether the elephants will continue to avoid the sound of angry bees after hearing it several times. She hasn't tested enough groups yet to know, but her initial (最初的) results were promising enough to begin trials with farmers. She has now begun placing speakers in the fields to see if elephants are frightened away.

    Not long ago, a good friend of mine asked me to help him in a halfway house in Nashville. I agreed and made my way there one evening.

    When I got there, I sat with my friend and talked about how he ended up there. As we talked, another man came up, lighting up his cigarette as he sat down. He had dark, leather skin, and looked like he had endured the sun, the rain, and the wind for long, long time. I couldn't tell how old he was, but I was sure that he was younger than he looked.

    Through a bit of conversation, I found out that he had been on the streets for many, many years.

    Without my asking, he started describing life as a homeless man. How he got food; how he stayed warm; how he got money. And he told me something that caught my attention.

    He said, "You want to know how I keep my stuff safe at night?"

    "Sure," I replied.

    "I put it up in the trees."

    "Why is it safe in the trees?" I asked.

"The homeless are always looking for treasure on the ground— coins, something someone's dropped, half-smoked cigarettes. I know if I put my stuff in the trees, they'll never find it because they never look up. Never. "

    Profound words from an unexpected place. And his message is for all of us.

We all have our particular search. We're looking for treasure on this earth. But what we are REALLY looking for is right there above us. There's really nothing we need on the ground.

    In fact, it's surrounding us.

    Have you ever wished you could grow fresh fruit in your garden but worry about there not being enough space, or it won't look pretty, or it's too difficult?

    What if I was to tell you that even a beginner can successfully grow a wide variety of fruit from apples and pears to cherries, blueberries and raspberries, and possibly even figs or nectarines?

    The first thing you need to know: the sweeter the fruit, the more sun it will require. If you have a sunny wall it's an ideal place to train a sun-loving fruit tree like a peach or an apricot. Plant the tree at the base of the wall but not too close (about 30cm is about right) in soil enriched with fertilizer (肥料). As it grows, splay (整枝) the branches evenly and attach them to the wall. As the plant grows gradually cut out old untidy branches and tie in new healthy branches. The idea of splaying or “fanning” is that as much sun as possible gets to the fruit, so it can ripen beautifully and maximize your crop.

    Choose a variety that won't grow too large. In slightly shadier spots you can grow gooseberries or raspberries. Most of these come in compact (紧凑的) varieties and can also be fan-trained against a wall if space is an issue.

    I have a tiny orchard (果园) of space-saving apple, pear and plum trees bought as single vertical stems (茎) which I grow in pots. They grow to a maximum of 2m high and no wider than 45cm. My children love them! Simply cut back the side stems to about 10cm at this time of year and you're good to go. Just remember that pot-grown plants rely totally on you for their food and water.

    As a gardener I was quite late to fruit-growing, but I realized quickly that it becomes an addictive hobby. And as a complete bonus I've noticed a definite increase in my bee population over the past few years. There's free food, and it's good for the environment too. What could be better?

    Food Parts You Should Never Throw Away in the Garbage

    Pineapple Core (果心)

    When you carve out the core of t pineapple, don't throw it in the garbage. You can use the pineapple core for all kinds of recipes, and there are tons of vitamins and  minerals hiding within.To use the pineapple core: cut it and add it to fruit salad, put it into smoothies (水果雪泥), cut it into cubes and freeze for law use, or simply add it to water or even tea to improve flavor.

    Kiwi Skln

    If you never thought you could eat kiwi in the way you eat a peach, think again. That skin really is good for you and contains a lot of vitamin C, and in fact, it's also higher hi fiber than the rest of the fruit. Of course, that rough, ugly skin isn't for everyone, so if you don't like it, try adding a whole kiwi to a smoothie to hide the taste of the skin.

    Banana Peel

    Most of us eat the banana without giving the soft peel a second thought. Here's why that's a mistake: banana peel contains tryptophan (色氨酸), which increases "the happiness hormone" to help with mood regulation and nerve system. There are a few creative ways to use the peel. Cook or boil for at least 10 minutes to soften. You can add it to smoothies, stir-fries, or soups. And, for a treat, simply slice and bake a banana with the skin on.

    Water melon Skin and Seeds

    The delicious, red inside makes for a refreshing snack or juice, but you're able to get some powerful nutrients in the skin and seeds as well. Cut out the white part under the green outside and use it in your cooking. It has vitamin C and B6, to keep you healthy. As for the seeds, you can roast them in the oven. Then add them to salads or to nut snacks.

    Back in 1988, I was working at the University of Bonn in Germany as a research fellow. I took some time off in early May to visit a friend, who was the director of a museum in Viterbo, in central Italy. I set out by train, which crossed the Swiss border to reach Zurich, winding through valleys and along hillsides, and entering tunnels and making its way through the Swiss Alps. The scenery was so beautiful.

    The train then crossed the Italian border before passing through Milan and Florence, then finally stopping in Rome. I was lucky, as my hotel was close to the railway station. The next morning, I had a coffee at a nearby café and eagerly set out to visit as many of the famous Roman landmarks as possible.

    The following day I headed back to the train station, intending to take a short train ride to Viterbo to meet up with my friend. When I arrived at the station and attempted to locate the correct platform, I quickly realized that the station was closed for an upgrade (升级). For a moment my mind went blank and did not know what to do. My biggest problem was my luggage—my suitcase and hand luggage were so heavy that I couldn't move about easily. As I don't speak Italian, I could not ask anyone for instructions. I dragged my suitcase about 100 meters to a nearby motor mechanics. A tall, strong man of about 50 years of age was working there and I excused myself and asked where the nearest station was. I am sure that he did not understand me properly but he could easily guess that I was looking for a station. He replied, but I did not understand.

    He smiled, wiped his hands and said something, which I guessed to mean "come along". So I dragged my suitcase along and followed him. He opened the door of his car, motioned to me to get in and then drove for a few minutes to the next station. I got out, unloaded my luggage, then shook his hand with thanks. He smiled back and drove away.

    There was no time to hug or exchange names  I understood he was busy and in the middle of his work. I was moved so much by his generosity that I have never forgotten him.
