Humans aren't the only ones getting a buzz from coffee.Caffeine can improve memory among honeybees and lead to better pollination .According to a recent study published in the journal Science. The study was conducted by a team of researchers at Newcastle University in the United Kingdom.They found that the nectar of some flowers,such as those from grapefruit and lemon plants,as well as certain coffee flowers,contains low doses of caffeine.To get bees to feed on these flowers,the team trained the insects to associate food with the smell of the flowers.They also trained another group of bees to feed on nectar from flowers that were sweetened with a sugar, but did not contain caffeine.After 24 hours,the bees trained on caffeinated flowers returned to these plants three times as often as those trained on the sweetened flowers returned to the uncaffeinated plants. Professor Geraldine Wright led the researchers."Remembering floral traits is difficult for bees to perform at a fast pace as they fly from flower to flower and we found that    caffeine helps the bee remember where the flowers are,"Wright said in a statement. Improved memory led to the better pollination.That's because once bees sip the caffeine  nectar, they continue to look for more coffee plants to pollinate.This also suggests that caffeine  plays a role in improving the bees'ability to search for food. Researchers found that caffeine's effect on the bee brain is similar to its effect on mammals."The change is similar to that produced by caffeine in neurons associated with learning and memory in the rat brain,"Wright said. Bee populations have declining since 2007.The dramatic drop in the insects'numbers has  serious effects for ecosystems and the farming industry.Bees are needed in the reproduction of  crops and spreading wild flower species.Understanding what keeps bees buzzing could help to make sure that the insects are able to remember and pollinate their favorite flowers.

Ogilvie the detective arrived. Both the Duke and Duchess were extremely nervous. The Duchess went to the door herself. The detective's piggy eyes surveyed her. His gaze moved on to sweep the spacious, well-decorated room, and the Duke. "Pretty neat set-up you've got."Ogilvie said slowly. The Duchess said sharply, "Imagine you didn't come here to discuss the decoration." "No, Madame. I like nice things, though. Like that expensive car of yours. The one you keep here in the hotel." "In what way does our car concern you?"The Duchess had sat in a straight-backed chair. "Now," he said."You two were in the hit-and-run." She met his eyes directly. "What are you talking about?" "Don't play games, lady. You saw the newspapers. There's been plenty on radio, too." Ogilvie's words spat forth with sudden strength. "You listen to me. This city's mad -- everybody. When they find who killed that kid and her mother, and run away, what will they do? Now I know what I know, and if I do what by rights I should, there'll be police here. But I come to you first, so you could tell your side of it to me." The piggy eyes blinked, then hardened. "If you want it the other way, just say so." The Duchess--three centuries and a half of in-born pride behind her--did not give in easily. Springing to her feet with great anger, gray-green eyes burning, she faced the detective straightly. Her tone would have frightened anyone who knew her well. "You unspeakable blackguard! How dare you!" Ogilvie said nothing. But the Duke cut in, "It's no go, old girl, I'm afraid. It was a good try." Facing Ogilvie, he said, "What you accuse us of is true. I was driving the car and killed the little girl." "That's more like it," Ogilvie said, "now we're getting somewhere." The Duchess sank back into her chair. She asked, "What is it you know?" "I'll tell you, I got a curious nature. You and your wife drove home, you were driving, after a drink. Last night I saw you come in--through the basement, looking shaken, the pair of you. I got wondering why. Like I... In the eyes of the Duke and Duchess, Ogilvie was   _  . A) professional, brave but dirty B) smart, sensitive and helpful C) greedy, tough but flexible D) honest, clever and reliable

It's the dieting fashion that is sweeping the world, and encourages fasting   for two days of the week. But does it work? People are starving themselves to lose weight, with a dieting trend known as the "fast diet" growing in popularity. The method is also known as the 5:2 diet, and consists of eating normally for five days of a week and cutting calories to about 25 percent of normal intake during other two days. Men consume just 600 calories on the two fast days, while women are limited to 500 calories. Notably, the two fasting days should not be _ . The dieter should have at least one normal eating day in between. In the best-selling book The Fast Diet: Lose Weight, Stay Healthy, and Live Longer with the Simple Secret of Intermittent   Fasting by Dr. Michael Mosley and Mimi Spencer, the two authors claim that the 5:2 diet not only promotes weight loss, but also benefits health, offering protection from disease, improved cognitive   function and increased lifespan. The diet originated in the United Kingdom and became popular in the United States. Now, it is gaining popularity among the Chinese middle-class. Zhong Minghui, who is 178 cm tall and used to weigh 100 kilograms, finds fasting effective in weight control. He works in the sales department of a trade company and used to drink and eat a lot after work. After sticking to the fasting diet for five months, he managed to lose about 20 kilograms. "Actually I did not exactly rely on the 5:2 diet to lose weight. My fasting was more extreme. I almost completely cut off my supper every day and only ate some fruit. I also used an app to calculate the calories in the food I ate and was cautious of not eating any high-calorie food. I did about an hour's aerobic exercise   every day. Fasting is definitely effective, but I think sports also help," he says. "I do not really believe that fasting is the magical cure-all  , but my high blood sugar has improved," he adds. The US Academy of Nutrition and Dietetics says that although there is evidence that intermittent... Which is the best title of the passage?
