Active Turbulence

Ricard Alert et al.

Summary: Active fluids, such as bacterial suspensions and sperm cells, exhibit complex spatiotemporal flows reminiscent of inertial turbulence. This phenomenon, known as active turbulence, is characterized by power-law scaling and the absence of energy cascades. The emergence of power-law scaling and the self-organized nature of energy injection distinguish active turbulence from inertial turbulence.

Emergence of active turbulence in microswimmer suspensions due to active hydrodynamic stress and volume exclusion

Kai Qi et al.

Summary: This study presents computational simulations of spheroidal model-microswimmers confined between two walls, revealing two collective dynamic states, depending on density and hydrodynamic interactions. Microswimmers exhibit an highly-dynamic collective motion with large-scale swirling patterns denoted as active turbulence. Various approaches have been applied to elucidate similarities and differences of inertial hydrodynamic and active turbulence.

Microfluidic production and characterization of biofunctionalized giant unilamellar vesicles for targeted intracellular cargo delivery

Oskar Staufer et al.

Summary: Researchers have developed a microfluidic-based mechanical droplet-splitting pipeline for the production of carrier-GUVs with diameters of around 2 μm, allowing for efficient cargo loading and precise control over the properties of GUV membranes. By investigating GUV-cell interactions, they achieved targeted cellular GUV delivery and explored strategies for intracellular GUV cargo release through lysosomal escape. This delivery technology could lead to more efficient drug administration and enable targeted delivery of advanced cargo like microparticles, viruses, or macromolecular DNA-robots.

Topological defects in the nematic order of actin fibres as organization centres of Hydra morphogenesis

Yonit Maroudas-Sacks et al.

Summary: The study reveals that the nematic order of actin fibers in Hydra regeneration plays a crucial role in morphogenesis, with topological defects acting as organization centers for morphological feature development. Fibre alignment sets the regenerated body axis and defect sites form organizing centers for the developing body plan.

Viscoelastic control of spatiotemporal order in bacterial active matter

Song Liu et al.

Summary: Active matter is composed of units that generate mechanical work by consuming energy, such as living systems and biopolymers. The goal is to understand and control the self-organization in space and time. Most active systems exhibit spatial order or temporal synchronization, while simultaneous control of spatial and temporal organization requires complex interactions.

Density fluctuations and energy spectra of 3D bacterial suspensions

Zhengyang Liu et al.

Summary: This study investigates density fluctuations in three-dimensional wet active fluids and demonstrates the existence of giant number fluctuations in low-concentration bacterial suspensions. The anomalous scaling is shown to persist well before the transition to active turbulence, challenging the common view of dense bacterial suspensions as active polar fluids.
