Recent research emphasizes the role of mechanical forces in tissue development.Study by Konstantin Doubrovinski explores how developing fruit fly tissue stretches.Previous observations of tissue extension puzzled researchers due to a non-zero exponent.Experiments ruled out viscosity as the cause of the non-zero exponent.Researchers used ferrofluid droplets to manipulate Drosophila epithelial cells for measurements.Observations of power law scaling law confirmed over varying time scales.Simulation by Mohamad Ibrahim Cheikh unexpectedly yielded the observed power law.Researchers simplified the complex model to a lattice of springs to understand the system.Experimental and theoretical curves could be rescaled, supporting the proposed model.Findings could have implications beyond fruit flies to other developmental stages and organisms.
