…不仅仅是一个红牛。你必须具备正确的代谢途径。  NSF亮点 的工作 格鲁吉亚大学的萨曼莎乔伊研究微生物在深度,黑暗,有害,氧气的超咸生态系统中如何生存和茁壮成长,这可能就像生命起源于那样的原始渗流。这项工作在几周后享受了一篇论文 自然地球科学。乔伊’S团队表明,活跃的泥火山和相当盐水池不仅提供不同类型的微生物,而且不同类型的新陈代谢。这两者对比周围水和沉积物的微生物。 Joye,纸上的铅,假设这反映了从沉积物表面低于沉积物表面的溶解有机物的差异以及两个位点之间的流体中的对比流量。


NSF网站有Samantha Joye的视频讨论了这些发现。

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.
