Model captures border cell cluster migration features in Drosophila
What the study found A biophysically informed phase-field model reproduced key features of border cell cluster migration in the Drosophila melanogaster egg chamber. The model included a contact-mediated propulsion mechanism called Tangential Interface Migration (TIM) and captured motion shaped by tissue geometry and chemical cues. Why the authors say this matters The authors conclude that…
Microscopic network properties limit domain growth in phase separation
What the study found Intrinsic strand- or network-level length scales in elastic polymer networks can impose local constraints on coarsening, leading to finite-sized phase-separated domains. The study also finds that the size of these domains is highly correlated with microscopic network properties and depends surprisingly little on the network's bulk elasticity. Why the authors say…
Hypergravity was linked to measurable changes in HeLa cell viscosity
—
in MedicineWhat the study found The study found measurable changes in intracellular viscosity in HeLa cells exposed to hypergravity. It also indicates that Single-Particle Tracking (SPT), a method that follows particles inside cells, can be used to measure this effect. What the authors say this matters The authors frame this as relevant because intracellular viscosity affects…
