The law of hydrodynamics can contribute to our understanding of how a cluster of embryonic cells can transform into an animal within the first 36 hours of development, according to research recently published in European Physical Journal E.
Vincent Fleury, a researcher at the Paris Diderot University, studied the early stage of development when embryonic cells first form a flat sheet of cells before folding into a U-shape, resembling a folded pancake. He demonstrated that the formation of a chicken’s head is a consequence of the collision between both sides of the embryo flowing at constant speed towards each other.

Rigid two-state and crossbridge are two models of motor assemblies widely used in the literature. But up to now they had never been studied and compared systematically. In cells, motor proteins use chemical energy to generate motion and forces. This thorough comparison presented in EPJE shows that theforce response to a small displacement step is similar in both models to the delayed stretch activation observed in oscillating muscles.

A new theoretical model which helps to understand how to best avoid jamming of soft matter.
In a study recently published in the European Physical Journal E (EPJE), a German scientist constructed a theoretical model to understand how to best avoid jamming of soft matter that can be applied in food and cosmetics production.

Tiny polymer droplets that crystallize on a surface are a shrewd expedient to study the birth of a polymer crystal by the elusive homogeneous nucleation mechanism. In most cases, take for example the dust particle in a snowflake, nucleation starts from a heterogenous defect. Homogenous nucleation is difficult to study because of the prevalence of defects in any bulk sample. Crystallization in small droplets alleviates this difficulty in a manner that is conceptually simple: subdivide the system into more domains than the number of defects. If the domains greatly outnumber the defects then only the homogenous mechanism can induce nucleation in a defect free compartment.
