Compass: The Hydrophilic Dance of the Tobacco Mosaic Virus

WITH ROMANIAN SUBTITLES
Join us for an enlightening episode of Compass on Cotidianul TV, where we delve into the fascinating world of virology and nanotechnology. Our esteemed panel includes Professor Alexander Bittner from CIC nanoGUNE BRTA and Ikerbasque, Basque Foundation for Science, Professor Annalisa Calò from the Department of Electronic and Biomedical Engineering at the University of Barcelona and the Institute for Bioengineering of Catalonia (IBEC), and Professor Christina Wege, the Head of Research Unit Molecular & Synthetic Plant Virology from the University of Stuttgart. This expert trio will be moderated by Radu Golban as they discuss the groundbreaking research on the water-binding properties of the Tobacco Mosaic Virus TMV / and its implications for understanding viral behavior in varying humidity conditions.
In this broadcast, we explore the intriguing findings from their latest paper titled "Nanoscale Wetting of Single Viruses," which investigates how TMV interacts with moisture at a nanoscopic level. Could these interactions influence weather patterns such as rain or drought? Tune in to find out!
The paper discussed in this broadcast, authored by Annalisa Calò et al., examines how individual TMV particles interact with water vapor at different relative humidity levels using advanced atomic force microscopy / AFM techniques. The study reveals that TMV can adsorb a thin layer of water, about ~1 nm thick on its surface at lower humidities at about below 60%. At higher humidities higher 100%, larger water droplets condense between TMV particles.
The research provides insights into how environmental moisture affects viruses, potentially influencing their stability and transmission. While it's a leap to suggest that viruses like TMV could directly produce rain or drought, understanding their interaction with water vapor could have broader implications for atmospheric science.
In simpler terms, imagine TMV as tiny rods that can attract a layer of water around them. When the air is somewhat dry, they wear a very thin coat of water. As it gets more humid, they start to gather more water, eventually creating small puddles between them when it's really damp. This ability to attract and hold water might tell us more about how viruses survive in different environments and even hint at their role in larger natural processes.
