Heterogeneous anomalous transport in cellular and molecular biology
TA Waigh, N Korabel - Reports on Progress in Physics, 2023 - iopscience.iop.org
It is well established that a wide variety of phenomena in cellular and molecular biology
involve anomalous transport eg the statistics for the motility of cells and molecules are …

Active colloids on fluid interfaces
We review recent work on active colloids at interfaces, including self-propelled colloids that
move by generating a propulsive force, and driven colloids that move under external fields …

Boosted molecular mobility during common chemical reactions
Mobility of reactants and nearby solvent is more rapid than Brownian diffusion during
several common chemical reactions when the energy release rate exceeds a threshold …

Anomalous transport of tracers in active baths
We derive the long-time dynamics of a tracer immersed in a one-dimensional active bath. In
contrast to previous studies, we find that the damping and noise correlations possess long …

Odd diffusivity of chiral random motion
Diffusive transport is characterized by a diffusivity tensor which may, in general, contain both
a symmetric and an antisymmetric component. Although the latter is often neglected, we …

Anomalous diffusion and Lévy walks distinguish active from inertial turbulence
Bacterial swarms display intriguing dynamical states like active turbulence. Now, using a
hydrodynamic model, we show that such dense active suspensions manifest superdiffusion …

Active carpets drive non-equilibrium diffusion and enhanced molecular fluxes
F Guzmán-Lastra, H Löwen… - Nature Communications, 2021 - nature.com
Biological activity is often highly concentrated on surfaces, across the scales from molecular
motors and ciliary arrays to sessile and motile organisms. These 'active carpets' locally inject …

Noise-induced acceleration of single molecule kinesin-1
The movement of single kinesin molecules was observed while applying noisy external
forces that mimic intracellular active fluctuations. We found kinesin accelerates under noise …

Stochastic thermodynamics of fractional Brownian motion
This paper is concerned with the stochastic thermodynamics of nonequilibrium Gaussian
processes that can exhibit anomalous diffusion. In the systems considered, the noise …

Single‐cell/nanoparticle trajectories reveal two‐tier Lévy‐like interactions across bacterial swarms
Y Sang, X Wen, Y He - View, 2022 - Wiley Online Library
Swarming bacteria can organize themselves into different local communities, ranging from
active cell rafts to reticular biofilms. How millions of motile and immotile cells are dynamically …
