the bridge in my background is also from Kolkata/Calcutta :)

Great questionI might offer there are also cellular interractions (immune and mobile and growing cells) physically coming in proximity, touching, etc

Are the bacteria body and flagella separately labelled?

How should we think about bacteria-wall interactions? Are pore walls (hydrogel) adhesive and sticky causing trapping or walls are slippery?

ok

What defines the wave speed?

Thanks,great

question from Tim Bilash: have you looked at effect of electric field/ magnetic applied or changing charge of medium?

In the end, can we think of this effect as an emergent surface tension (or line tension) for the front?

@Dan great question — we were initially thinking along those lines, but couldn’t figure out the right mapping to an interfacial tension given the complexities of nutrient sensing driving chemotaxis. If you have any thoughts, would be happy to chat more!

question from Tim Bilash: IS the flagella frequency or strength of flagella stroke changing?
