微生物学的重要工具:Christina Kellogg的垃圾袋

CK在垃圾袋暗室,信用StéphaneHourdez搭便车’Galaxy的指南 建议拥有自己的毛巾总是有用的。类似地建议海上显微镜,带来大型黑色垃圾袋和管道带。

病毒颗粒非常小,通常小于200nm。对于透视,人头头发的直径约为50,000nm。在过去,看到和计算海洋病毒的唯一方法是通过使用透射电子显微镜(TEM),昂贵且复杂的装置,其使用电子而不是光来可视化小物体。然而,已经开发出荧光染料,其发射非常亮的光,并且这些染料可用于染色病毒颗粒内的DNA。即使病毒颗粒很小,发出的光足够明亮,使其可检测到–在100倍放大的便携式荧光显微镜下,效果就像在夜空中的计数星。显然,背景越越深,看看微小的灯光。这种作品通常在暗室中完成。大多数船只没有暗室。我想你可以看到垃圾袋和管道胶带进来的地方…他们都需要构建自己的私人暗室。

Craig McClain is the Executive Director of the Lousiana University Marine Consortium. He has conducted deep-sea research for 20 years and published over 50 papers in the area. He has participated in and led dozens of oceanographic expeditions taken him to the Antarctic and the most remote regions of the Pacific and Atlantic. Craig’s research focuses on how energy drives the biology of marine invertebrates from individuals to ecosystems, specifically, seeking to uncover how organisms are adapted to different levels of carbon availability, i.e. food, and how this determines the kinds and number of species in different parts of the oceans. Additionally, Craig is obsessed with the size of things. Sometimes this translated into actually scientific research. Craig’s research has been featured on National Public Radio, Discovery Channel, Fox News, National Geographic and ABC News. In addition to his scientific research, Craig also advocates the need for scientists to connect with the public and is the founder and chief editor of the acclaimed Deep-Sea News (http://jiaxiangsuji.com/), a popular ocean-themed blog that has won numerous awards. His writing has been featured in Cosmos, Science Illustrated, American Scientist, Wired, Mental Floss, and the Open Lab: The Best Science Writing on the Web.

  1. 我想这张照片(或类似的东西,我’M确定我在我的工作计算机上有一些),需要添加到我的屏幕保护程序中。也就是说,如果我决定放弃鱿鱼。
