Adaptation to extreme stress under the growth-survival fitness trade-off
Nandita Chaturvedi, Charuhansini Tvishamayi, Shashi Thutupalli
Microbial adaptation to extreme stress, such as starvation, antimicrobial exposure, or freezing often reveals fundamental trade-offs between survival and proliferation. Understandi…
De novo emergence of metabolically active protocells
Nayan Chakraborty, Shashi Thutupalli
A continuous route from a disordered soup of simple chemical feedstocks to a functional protocell -- a compartment that metabolizes, grows, and propagates -- remains elusive. Here,…
Explosive dispersal of non-motile microbes through metabolic buoyancy
Jimreeves David, Shashi Thutupalli
For non-motile microorganisms, spatial expansion in quiescent fluids is presumed to be limited by diffusion. We report that microbial colonies can explosively circumvent this const…
Temperature switchable self-propulsion activity of liquid crystalline microdroplets
Manoj Kumar, Siddharth Sane, Aniruddh Murali +1
We report on a switchable emulsion droplet microswimmer by utilizing a temperature-dependent transition of the droplet phase. The droplets, made from a liquid crystalline (LC) smec…
