In this podcast, the hosts delve into the fascinating topic of bacterial exchange through handshakes, conducting experiments to examine the types and duration of bacteria transfer. They explore the potential applications of this research in forensics, disease outbreak prediction, and personalized medicine. Surprisingly, their experiment shows a lack of bacterial transfer during handshakes. The hosts also discuss microbiomes, body odor, and tease an upcoming show about a microbial robbery.

Bacterial Transfer During Handshakes
In a podcast episode, the host explores the transfer of bacteria during handshakes. The experiment involved two individuals shaking hands, and it was expected that there would be an exchange of microbes. However, the results showed that one person's bacteria completely failed to affect the other person, while the other person's bacteria successfully colonized the first person's hand and remained there for an extended period. The experiment sheds light on the complex dynamics of microbial transfer and colonization.
Applications in Microbiome Detection
The podcast episode also delves into the potential applications of microbiome detection. Scientists are now able to identify bacteria on individuals using their DNA, which can have various implications. For instance, it could be used in forensics to determine who has been present in a specific location. Additionally, monitoring the microbiome in town sewer systems could provide early detection of disease outbreaks, allowing for prompt preventive measures. The episode highlights the promising field of microbiome research and its potential for various real-world applications.
The Unique Microbial Profile of Each Individual
The episode discusses how the microbial profile of an individual is established from birth and continues to evolve throughout life. The microbiome acquired during childbirth and early interactions with the environment play a significant role in shaping an individual's unique bacterial composition. This microbial fingerprint remains relatively stable and can even persist for long periods on surfaces and other individuals. The podcast explores the intriguing dynamics between our bodies and the microbial world, highlighting how bacteria can become both guests and invaders in our ecosystems.
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.
