If you’ve heard of Twitter but don’t exactly know what it is or how it works, you’re in good company. In the past two months a bunch of my friends, ranging in age from early 20s to late 30s, have asked me about Twitter — or Tweeter, as one person accidentally called it. To clear things up, I’ve put together a basic Twitter guide that explains how to use it, Twitter lingo, privacy options, mobile ...

大脑活动的新研究揭示了爱情保鲜的源头。脑成像研究表明，有些人即使在20年的婚姻生活后爱情还如同年轻时炽热。 纽约爱因斯坦医学院的研究人员在比安卡•阿塞维多主持下进行研究，想知道爱情或爱情引发的大脑活动是否能长期持续。所有人都松了一口气——答案是肯定的。该小组于11月16日神经科学协会的年度会议上公布了这一发现。 新的数据表明，深陷爱情中的人其大脑活动可在脑部爱情区域平均持续21年。“现在我们有生理证据表明爱情可以保鲜，”新泽西州新不伦瑞克罗格斯大学的生物人类学家，作者之一，海伦•费希尔说。 研究报告作者之一，阿尔伯特爱因斯坦医学院的露西•布朗说，大多数夫妻在一起生活多年后，感情从执着狂热转为柔和舒适。但研究人员发现一小群异类，他们同伴侣一起多年，至今仍与当初初陷爱河时一样互爱对方。 自2005年使用功能性磁共振成像大脑成像进行研究始，研究人员就知道，如果一个人最近一段时间（平均7个月）陷入爱情，大脑中有一片区域即腹侧被盖区就会被激活，就会有其心上人的影像。但是，也许并不是巧合，腹侧被盖区也可能被可卡因激活，因为该区域可控制自然刺激物多巴胺的产生。研究人员得出结论认为，这一区域与初期阶段热烈炽热的爱情的产生有关。目前还不清楚这一地区在20年后是否仍然活跃。 科学家们监测受试者脑部活动使用功能磁共振成像，其图像被展示给其爱人，他们平均已婚21年。自称20年后仍疯狂地爱着对方的人与刚刚一起陷入爱河几个月的人，其显示在大脑腹侧被盖区的大脑活动非常相似。 与此同时，早期爱情和长期爱情的主要差异表明，长期一起生活有潜在的益处。长期相爱的爱人控制冷静和抑制疼痛的脑部区域活动比较活跃，而刚陷入爱情中的人其控制执着和焦虑的脑部区域则比较活跃。“不同的是，在长期爱情里，执着、狂躁和焦虑已转变为平静，”费希尔在新闻发布会上说。 “选择配偶时，有一个循序渐进的过程。”研究员托马斯•柯蒂斯说。他对草原田鼠（众所周知的终身一夫一妻制的小动物）的配对结合颇有研究。他认为许多草原田鼠研究，包括他自己在俄克拉何马州塔尔萨俄克拉何马州立大学的研究，都支持这些人类长期配对的新发现。事实上，当研究人员取出田鼠大脑中的腹侧被盖区，也就是能被爱情激活的人类脑中的同一区域，田鼠将不再寻求配偶。 要理解复杂的人类的爱，科学家计划进行更多的脑功能成像研究。下一步将是定期监测慢慢进入长期关系的新人夫妇的大脑活动。阿塞维多说，他们希望了解在例如孩子出生或夫妻关系出现矛盾等大事时，大脑将如何活动。（环球科学编译 张琦） 更多精彩文章：http://www.sciam.com.cn/sort.php?sortid=22

A one-eyed San Francisco artist wants to replace her missing eye with a Web cam - and tech experts say it's possible."I'd always given thought to using cameras to restore sight to the blind," said Dr. William Danz, whose patient, Tanya Vlach, wants the groundbreaking device. "This is a little different, more like James Bond stuff." Vlach, who lost her eye in a 2005 car accident, wears a realistic acrylic prosthesis, but she's issued a ...

Over the past couple of years, Pure Digital Technologies has changed the way people think about video cameras by turning these heavy, expensive, intimidating devices into affordable, user-friendly gadgets that fit into a shirt pocket. To keep the prices of its Flip camcorders affordable, Pure Digital always made some sacrifices in quality and style. And though the company improved on style in June by releasing the sleek $180 Flip Mino, it stuck with standard definition ...

The Flip goes HD! Good stuff. I have the original flip and definitely love it -- we take it wherever we go. The HD version is a good addition to the family.

Randall's ESL Cyber Listening Lab：http://www.esl-lab.com/ 網站主人是Randall Davis，美國人，擁有TESL(Teaching English as a Second Language)碩士學位（也就是專教母語不是英語的人英語），曾在日本的大學教過八年英文。 用這個網站練習英聽的優點不少，免費是第一個優點。練習內容作了難度區分，可以循序漸進的訓練（Difficult等級差不多是托福TOEFL電腦考試聽力測驗的速度）。每個練習除了會提供內容台詞，還設計了題目測驗是否聽懂了重點內容，如果有特殊單字，也會特別註解。 不過，如果你要練習英國口音的英語（電影哈利波特就是英國口音），這網站可能就不太適合了，BBC（英國廣播公司）中文網的英語教學會比較適合。 相關文章： （孩子）學習的語言決定了未來的競爭力？

Change is a familiar concept in the mobile-phone industry. Most recently, Apple and Google introduced mobile devices with two vital innovations: They run on fast 3G networks and use touch screens. Yesterday Research In Motion (RIMM), maker of the BlackBerry, brought out a device that goes halfway: the BlackBerry Bold, which runs on AT&T’s 3G network, but doesn’t have a touch screen. The $300 (with two-year contract) Bold doesn’t pose as RIM’s real iPhone competitor; ...

Does God hear our prayers when there is sin in our lives? Psalm 66:16-20 “Come and listen, all you who fear God; let me tell you what he has done for me. I cried out with my mouth; his praise was on my tongue. If I had cherished sin in my heart, the Lord would not have listened; but God has surly listened and heard my voice in prayer. Praise be to God who has ...

My project team is in the beginning stages of running some in-home research interviews right now, so I’ve been preparing the questions we want to ask and the activities we might want to try. I brainstormed, wrote lots of ideas down on stickies, asked my teammates about big themes we wanted to cover, and then carefully wrote up the top questions in a nice big list. But then I realized - the list format is ...
