你每天会抽多少空来看看报纸呢? 我是经常一篇新闻都看不下来,所以导致很多单词都不知道。 有一次考试考了很多理应知道的词 比如残奥会。余震。我都自己瞎写的 。 额 还有blue chips (蓝筹股票) 这个帖子 一是希望跟大家一起 比较有动力一点。 二也是想多带动咱们版块的气氛 (一起努力噢。)。 三呢当然也是希望大家多学一点,不断进步 (学到老活到老)。 希望大家多多支持了 也希望大家也可以把自己看到的新闻拿上来一起看。(越多越好 多多益善) 重申。我们的目的。好好学习天天向上 let's go → Scientists in Britain close to cracking chicken-egg puzzle A file photo of a chicken and an egg. What came first, the chicken or the egg? Scientists in Britain think it was probably the chicken. What came first, the chicken or the egg? Scientists in Britain think it was probably the chicken, after using new computer technology to try and crack the age-old riddle. Researchers at the Universities of Sheffield and Warwick, in northern and central England, say the secret lies in the eggshell -- specifically the vital role played by a chicken protein in forming it. Scientists already knew that the protein, ovocledidin-17 (OC-17), plays a part in eggshell formation, but the new technology allowed the team to demonstrate exactly how the protein makes it happen. In a computer simulation, the OC-17 protein acted as a catalyst to kickstart the formation of crystals that make up an eggshell by clamping itself on to calcium carbonate particles. The OC-17 protein then dropped off when the crystal nucleus was large enough to grow on its own, freeing up the protein to start the process again. Eggshells are created when this happens many times over within a short period of time. "Understanding how chickens make eggshells is fascinating in itself but can also give clues towards designing new materials and processes," said Professor John Harding from Sheffield University, one of the authors of the research. "Nature has found innovative solutions that work for all kinds of problems in materials science and technology -- we can learn a lot from them," he added. (Read by Lee Hannon.

用新的计算机技术,破解了这个古老谜题。研究人员表示,关键在于蛋壳,特别是其中一种鸡蛋蛋白质在形成蛋壳中发挥的重要作用。这种蛋白质叫做ovocledidin-17(OC-17),已经被科学家们认为是形成蛋壳的一部分。但是新技术让研究团队能够精确地证明这种蛋白质如何发挥作用。在计算机模拟中,OC-17蛋白质作为催化剂发挥作用,通过与碳酸钙颗粒结合,启动组成蛋壳的晶体的生成过程。当晶体核足够大以独立增长时,OC-17蛋白质便会脱离,为再次启动过程铺平道路。由此生成一枚蛋需经历多次往返的过程。研究团队之一、谢菲尔德大学的约翰·哈丁教授说:“了解鸡是如何制造鸡蛋壳的是一件迷人的事情,但也可以给材料和工艺设计提供线索。人们可以从自然中找到解决材料科学和技术中各类问题的创新方法。”

    Dunno what god is thinking about! He wants to bake us or something. That’s not funny, NOT funny at all, god ya hear me, to hell with ya!!! ……*&^%$#.....@#%%^......

    It’s said that it’ll be hottest year in history, sometimes, I even think it’s hotter than Africa, ohh…my….look at me…..since when I am so black and shine!....ough….axxxxx…..

    It’s too hot that our company even came up with a policy that the workers can only come and work in the morning, then go home and sleep. That’s it, 5 hours

    Not woman, just girl.

    Woman is physically weaker than man, but we are mentally as strong as man. Therefore we ask for equal right and  position in marriage.Anyhow, it's an equal war between man and woman.

    At least there is a marriage.

    I don’t even think to he a BF at this age, uh…I am not getting younger any more, and what’s my problem!!!

    It has nothing to do with marriage actually, marriage itself is pretty simple, and it never change. However, people change. I don’t know since when people just don’t get satisfied so easily, and since when we are so damn inspiring to pursue the happiness which seems we can never he.

    I am not saying people who got divorced are out of mind or insane o

    没有,

    他回复的时候 我的标题还是 先有鸡后有蛋。

    再说了 就现在这个标题而言 也不是标题党 因为内容跟标题是吻合的。

    actually, I think it is 3-year itch, 4-year itch recently

    Seven-years has traditionally been the time when love and affection give way to disillusion and disappointment.

    But couples who manage to survive the seven-year itch would be wise not to get complacent.

    The biggest threat to modern marriages actually comes from the 12-year itch, research has revealed.

    First egg, then chicken. That’s it.

    It’ll totally freak me out if the chicken came first, you know, how weird it would be…aw….can you guys imagine that? C’mon, chicken is a little tiny fluffy thing that with eyes, ears, wings and legs, I really don’t think it could just come this way, I mean without an egg. However, it’s ok to an egg, how difficult do you think it could be to creat a round thing like that, huh….

    That’s it, that’s it, that’s it……..
