EPJ E - Embryo development obeys the laws of hydrodynamics

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.

EPJ E - Compare Motor Models: Two-State versus Crossbridge

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.

EPJ E - Unlocking jams in fluid materials

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.

EPJ E - Polymersomes made-to-measure

The use of polymersomes in drug delivery, medical imaging, micro-reactors or to mimic biophysical membrane phenomena is greatly dependent on the extent to which their properties can be controlled and tuned.

EPJ E - Gems for polymer scientists

EPJ E - Gems for polymer scientists

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.

Jean-Marc Di Meglio becomes Editor in Chief of EPJ E

We are very pleased to announce that Jean-Marc Di Meglio, Physics Professor at the University Paris Diderot, has been appointed Editor in Chief of EPJ E, with the special title of Commissioning Editor in Chief. From 1981 to 1994 he worked in the laboratory of Pierre-Gilles de Gennes at College de France, and was Professor at the University of Strasbourg from 1994 to 2002 The European Physical Journal E has benefitted from his editorial talent and vast expertise since 2007, when he joined the Editorial Board of the journal. Professor Di Meglio's work ranges from soap films to bubbles, polymers, colloids and vesicles. His latest interest is in biomechanics. Professor Di Meglio will work alongside Editors in Chief Daan Frenkel and Frank Julicher. We wish him a great experience in his new role.

EPJ E - How the fruit fly got its spots

EPJ E - How the fruit fly got its spots

The eye of the Drosophila (fruit fly) is characterized by a neat hexagonal patterns, a fascinating system to study pattern formation in biology. A recent paper published in EPJ E proposes a new mechanism to explain the emergence of this pattern.
