鸡（家鸡）的介绍
鸡（家鸡）的胚胎是一个极有价值的研究发育生物学的模式生物，部分原因是因为它们的大部分发育阶段发生在鸡蛋内，并在母体以外孵育的。因此，早期的发育阶段可以通过在蛋壳上简单地开个小孔而接近，观察和操控。由于有数十亿鸡在世界范围内繁育用于提供肉和蛋，科学家们全年都可很容易并低价获得大量的受精蛋。此外，鸡与人类有着显著的遗传保守性，因此通过鸡发现的调节发育的遗传机制也适用于我们自己的生物学。
本视频重点介绍了作为科学模式生物的家养鸡。从对鸡的系统发生的回顾开始，揭示了它们像其他鸟类，爬行动物和哺乳动物定义为羊膜动物的特征。呈现了鸡研究千年的亮点，从亚里士多德的关于胚外膜功能的推测到更近一些的获得诺贝尔奖的神经科学的发现。此外，我们还提供了一些目前在鸡胚上进行研究的例子，如发育过程中体内跟踪细胞运动和征用血管发展肿瘤（称为血管生成的过程）。

Alfredo Quinones-Hinojosa（Q博士）（霍普金斯达大学）：我是如何成为一名科学家
出生于墨西哥的Q博士，19岁时翻越美国边界的栅栏，成为加利福尼亚的一名农场工人。由于他自己的决心，努力工作和自律，以及来自家庭和朋友的大量支持，他离开了农场工作，完成了大学和医学院的学业，最终成为一位非常成功的医生、科学家和脑外科医生。
关于讲师：Alfredo Quinones-Hinojosa是约翰霍普金斯大学，神经外科学和肿瘤学，神经系统的细胞与分子医学的副教授，脑肿瘤外科手术的主任。Q博士作为一个专家外科医生，他致力于干细胞，在脑肿瘤的病因和治疗领域的研究。
Alfredo Quinones-Hinojosa (Dr. Q) (Johns Hopkins): How I Became a Scientist
At age 19, Quiñones-Hinojosa jumped the fence from Mexico to become a farm worker in California. Thanks to his own determination, hard work and discipline and a lot of support from family and friends, he left farm work, completed university and medical school, and ultimately became a highly successful physician-scientist and brain surgeon.
About the speaker: Alfredo Quiñones-Hinojosa is an Associate Professor of Neurosurgery and Oncology, Neuroscience and Cellular and Molecular Medicine and Director of the Brain Tumor Surgery Program at Johns Hopkins University. As well as being an expert surgeon, he researches the role of stem cells both in causing brain tumors and potentially in fighting them.
This talk was first released in iBioMagazine Issue 5.

科学家如何利用维基百科
Schulenburg outlines three main reasons why scientists should contribute to Wikipedia; you will learn a lot from the feedback of editors and readers, it is a chance to give back to the Wikipedia community, and your writing will have a much larger audience than in most traditional journals.

How does an English literature major ultimately end up as a cancer biologist? Varmus tells us of his circuitous path to becoming a scientist to illustrate the many routes that one can follow to a career in science.
科学家们的职业生涯规划师
Handelsman describes guidelines that she and her colleagues have developed to help scientists become better mentors. These include listening, asking questions, stating expectations and building independence. Good advice for scientists at all stages of their careers.
冒险和发现的爱，由科学家和登山者共享
Louis Reichardt has experienced both success and tragedy in his efforts to climb the world's highest summits. Here he recalls his spectacular ascents of the two highest mountains in the world. In 1978, he reached the summit of K2 making him the first American ever to do so. Five years later, he joined a team that reached the peak of Mount Everest via the challenging east face, a feat that has never been repeated. Reichardt discusses the impact of mountaineering on his scientific career and the love of adventure and discovery that is shared by scientists and climbers.
