Humans aren’t the only ones getting

Humans aren’t the only ones getting a buzz from coffee．Caffeine can improve memory among honeybees and lead to better pollination(授粉)．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(花蜜)of some flowers，such as those from grapefru it 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(花部特征)is difficult for bees to perform at a fast pace as they fly from flower t o 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(神经元)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．

人类不是唯一从咖啡到Buzz。咖啡因能提高记忆中蜜蜂和带来更好的授粉（授粉）。根据发表在科学杂志上最近的一项研究。

研究是由一个团队在英国纽卡斯尔大学的研究人员进行的。他们发现花蜜（花蜜）一些花，如那些从grapefru它和柠檬的植物，和某些咖啡花一样，含有少量咖啡因，要让蜜蜂在这些花上喂食，这个团队训练昆虫把食物与花的气味联系起来，他们还训练了另一组蜜蜂在用糖加糖后，却没有包含咖啡因，蜜蜂在花回到训练含这些植物的三倍那些训练的糖花回到有无

植物。教授杰拉尔丁莱特LED研究人员。“记住花性状（花部特征）是蜜蜂进行以快速的步伐，因为他们从一朵花飞到花，我们发现咖啡因有助于蜜蜂记得花朵在哪里很困难，”Wright在一份声明中说。

记忆力提高LED的更好，授粉。因为一旦蜜蜂喝咖啡因的花蜜，他们继续寻找更多的咖啡植物授粉。这也表明，咖啡因在提高bees'ability寻找食物所起到的作用。

研究发现，咖啡因的效果上的蜜蜂大脑类似于哺乳动物的影响。“变化是类似的，由咖啡因产生的神经元（神经元）与在大鼠的大脑学习和记忆相关的，”Wright说。

蜜蜂种群已经下降2007以来。在insects'numbers急剧下降，严重影响了生态系统和农业。蜜蜂在农作物繁殖需要推广种野花。了解是什么让蜜蜂嗡嗡可以帮助确保昆虫能记住自己喜爱的花授粉。
