Topics
Robert Krulwich:作者从小就对与肯尼迪总统握手后是否会残留细菌感到好奇,并设计了一个实验来验证这一想法。实验中,作者与Neil deGrasse Tyson握手,并对握手前后两人手上的细菌进行采样和分析。实验结果出乎意料,作者手上的细菌大量转移到Neil手上,而Neil手上的细菌几乎没有转移到作者手上。这一结果引发了对人体细菌生态系统和细菌转移机制的深入思考。 Jack Gilbert:作为微生物组中心的主任,Jack Gilbert解释了人体细菌的分布、转移方式以及人体微生物组的“创始者效应”。他指出,婴儿出生时会通过阴道分娩获得大量的细菌,这些细菌会伴随其一生。人体细菌的转移受到多种因素的影响,例如细菌的种类、数量、环境等。实验结果显示,作者手上的细菌能够成功转移,可能是因为一种链球菌破坏了Neil手上的细菌生态系统。 Neil deGrasse Tyson:作为实验的参与者,Neil deGrasse Tyson分享了他对实验结果的看法,并与作者就实验结果进行了讨论。 Siobhan Dolan:Siobhan Dolan作为一名妇产科医生和临床遗传学家,解释了婴儿出生时获得细菌的过程,以及这些细菌对婴儿的影响。她指出,婴儿出生后最初几小时接触到的细菌菌株,以及之后一年内接触到的细菌菌株,会伴随其一生。 Robert Krulwich: 作者回顾了他14岁时与肯尼迪总统握手的经历,并由此引发了对细菌转移的科学研究兴趣。他与科学家合作,设计了一个实验,模拟与肯尼迪总统握手,来研究细菌的转移。实验中,他与Neil deGrasse Tyson握手,并对握手前后两人手上的细菌进行采样和分析。实验结果显示,作者手上的细菌显著转移到了Neil手上,而Neil手上的细菌几乎没有转移到作者手上。这一结果表明,人体细菌的转移并非简单的双向交换,而是受到多种因素的影响。 Jack Gilbert: Jack Gilbert解释了人体细菌的分布、转移方式以及人体微生物组的“创始者效应”。他指出,婴儿出生时会通过阴道分娩获得大量的细菌,这些细菌会伴随其一生。人体细菌的转移受到多种因素的影响,例如细菌的种类、数量、环境等。实验结果显示,作者手上的细菌能够成功转移,可能是因为一种链球菌破坏了Neil手上的细菌生态系统。他进一步解释了细菌在不同环境中的竞争和生存机制,以及“创始者效应”在人体微生物组中的作用。 Neil deGrasse Tyson: Neil deGrasse Tyson作为实验的参与者,分享了他对实验结果的看法,并与作者就实验结果进行了讨论。他表达了对实验结果的惊讶,并对人体细菌生态系统的复杂性进行了思考。 Siobhan Dolan: Siobhan Dolan解释了婴儿出生时获得细菌的过程,以及这些细菌对婴儿的影响。她指出,婴儿出生后最初几小时接触到的细菌菌株,以及之后一年内接触到的细菌菌株,会伴随其一生。她还强调了母婴之间细菌转移的重要性,以及这种转移对婴儿免疫系统发育的影响。

Deep Dive

Chapters
This chapter tells the story of a young Robert Krolwich meeting President Kennedy and shaking his hand. It then segues into the world of microbes and the emerging science of identifying individuals by their unique microbial signature. This leads to the introduction of an experiment to recreate the Kennedy handshake and analyze the microbial exchange.

Shownotes Transcript

Back when Robert was kid, he had a chance encounter with then President John F. Kennedy. The interaction began with a hello and ended with a handshake. And like many of us who have touched greatness, 14 year old Robert was left wondering if maybe some of Kennedy would stay with him. Back in 2017, when this episode first aired, Robert found himself still pondering that encounter and question. And so with the help of what was brand new science back then, and a helping hand from Neil Degrasse Tyson, he set out to satisfy this curiosity once and for all.EPISODE CREDITS:Produced by - Simon Adlerwith help from - Only Human): Amanda Aronczyk, Kenny Malone, Jillian Weinberger and Elaine Chen.
