    Like people, plants experience stress. And also, like people, the response to that stress can determine success.

    Bad environmental conditions, such as drought, flood, heat and other stresses, affect yields (产量) more than crop pests and diseases. We are trying to find a way to equip plants with the ability to tolerate environmental stress and maintain high yields, said Stephen Howell, a professor of genetics and cell biology.

    Plant cells produce proteins (蛋白质) and ship them to different parts of the cell. Under normal conditions, these proteins are folded into their normal, healthy structures as they are produced. When a plant is under stress, its cells produce poorly folded or unfolded proteins. Then a built-in system senses this and “sets off an alarm in the cell,” said Howell.

    In response to the alarm, another protein (IRE1) starts working and creates a different process which activates (激活) the stress response genes whose products bring about defensive measures that help the plant survive.

    “As it turns out, responses that are activated under stress conditions actually inhibit the growth of plants,” said Howell. “This allows them to preserve their energy to survive the stress conditions.”

    For plants in the wild, this response is a help for survival, he said. In production of agriculture crops, however, this response reduces yields.

    “You don't want crop plants to stop growing,” Howell said. “You want them to continue to grow and produce even though they are under stress.”

    With the new understanding of this stress response, the next step may be to silence the alarm system, said Howell. “What may be important is to disable some of these stress responses. That may make the plant more productive under stress conditions.”

    It's that time of year when people need to lock their cars. It's not because there are a lot of criminals running around stealing cars. Rather, it's because of good-hearted neighbors who want to share their harvest. Especially with this year's large crop, leaving a car unlocked in my neighborhood is an invitation for someone to fill it with zucchini（西葫芦）.

    My sister, Sharon, recently had a good year for tomatoes. She and her family had eaten and canned so many that they had begun to feel their skin turn slightly red. That's when she decided it was time to share her blessings. She started calling everyone she knew. When that failed, she began asking everyone in the neighborhood, eventually finding a neighbor delighted to have the tomatoes. "Feel free to take whatever you want, "Sharon told her. Later that day, Sharon found that her garden had indeed been harvested. She felt happy that she could help someone and that the food didn't go to waste.

    A few days later, Sharon answered the door. There was the neighbor, holding a hot loaf of bread. The neighbor smiled pleasantly, "I wanted to thank you for all of the tomatoes, and I have to admit that I took a few other things and hoped you wouldn't mind. "

    Sharon couldn't think of anything else in her garden that had been worth harvesting and said so. "Oh, but you did, "the neighbor said. "You had some of the prettiest zucchini I've ever seen. "

    Sharon was confused. They hadn't even planted any zucchini. But her neighbor insisted that there really were bright-green zucchini in her garden. Sharon felt curious and decided to go to see where the zucchini had grown. The two of them walked together into the backyard. When the neighbor pointed at the long green vegetables, Sharon smiled. "Well, actually, those are cucumbers（黄瓜）that we never harvested, because they got too big, soft and bitter for eating. "

    The neighbor looked at Sharon, shock written all over her face. She gulped（哽住）a few times, and then, smiling, held out the bread, part of a batch she had shared all over the neighborhood. "I brought you a nice loaf of cucumber bread. I hope you like it. "

    About ten men in every hundred suffer from color blindness in some way. Women are luckier; only about one in two hundred is affected in this matter. Perhaps, after all, it is safer to be driven by a woman!

    There are different forms of color blindness. In some cases a man may not be able to see deep red. He may think that red, orange and yellow are all shadows of green. Sometimes a person cannot tell the difference between blue and green. In rare cases an unlucky man may see everything in shades of green — a strange world indeed.

    Color blindness in human beings is a strange thing to explain. In a single eye there are millions of very small things called "cones". These help us to see in a bright light and to tell difference between colors. There are also millions of "rods", but these are used for seeing when it is near dark. They show us shape but no color.

    Some insects have favorite colors. Mosquitoes prefer blue to yellow. A red light will not attract insects, but a blue lamp will. In a similar way human beings also have favorite colors. Yet we are lucky. With the aid of the cones in our eyes we can see many beautiful colors by day, and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible colors around us.

    I always feel sorry for world leaders busy dealing with fights between nations. When my three children were young, most days it was hard to keep my house from becoming a battlefield.

    It got worse as they grew older. Three years ago, Zack, then 16, couldn't make it through a day without making his sisters, Alex 11 and Taryn 9, angry.

    My husband and I tried to be understanding the boy at such an age. We reasoned, punished, and left heartfelt notes on his bed about how he was hurting our family. His answer was" I say it because it's true."

    I even tried telling the girls to fight back. Bad idea. Now I had three children at war. Whatever I said to them, they paid no attention. When there was no way out, I told everything to my sister, Mary, in an e-mail. She replied, "Don't e-mail me. E-mail him."

    Our son was online every day, mailing and talking with his friends. Maybe he would actually hear me this way. I didn't say anything different, but e-mail just took the tension away. There'd be no shouting or door banging. Zack wouldn't feel under attack.

    Zack didn't reply for days. When he finally did, his entire message was four small words. I smiled when I read them: "You're right. I'm sorry."

    The children still fought, of course, but Zack changed. Best of all, I now have a better way to talk with not one but three of them. I like it that they don't tune me out as much as they used to. They like not having to listen to me shouting to them. Or as Alex says, "You're so much nicer online."

    All I know is that the house is quiet. But we're talking.
