The shape of the interface between two fluids can be controlled by changing the refractive index contrast between the fluids, researcher from the Universite Bordeaux have shown. Optofluidics are methods based on the combination of optics and fluidics which have recently promoted innovative approaches to manipulate liquid interfaces. Since flows are optically driven, researchers call this emerging field optohydrodynamics. The recent paper published in EPJ E presents a fine example of optohydrodynamic actuation at the microscopic scale, based on experimental and predictive numerical results. This work illustrates one of the simplest manifestations of optohydrodynamics and provides a frame to anticipate further developments of contactless interface micromanipulation by lasers.

This July, during the International Soft Matter Conference 2010 in
Granada, Spain, Professor Sam Safran will give the EPJ E - Pierre
Gilles De Gennes lecture, associated with a prize given by the
publishers of EPJ.
This is the first edition of the *EPJE - Pierre-Gilles De Gennes Lecture Prize*, which takes the name from the illustrious Nobel laureate who founded EPJ E.
The Editors in Chief elected Prof. Sam Safran of the Weizman Instutite, Israel, as the prize recipient to acknowledge his leading research in soft matter and biological physics. The prize was also endorsed by the ISMC 2010 conference committee.
The prize will be presented to Prof. Sam Safram by Prof. Dominique Langevin (who is an Associate Editor of EPJ E) at the beginning of his plenary talk, 6 July at 8.30 am.

Grazing incidence X-ray diffraction, performed by Grelet and colleagues, reveals that thin films of discotic liquid crystals typically prefer to lie flat in columns oriented along the surface of their substrate. These materials are potentially useful for organic solar cells, but to achieve good performance from such devices, the column axis should rather be oriented vertical to the conducting substrate. However, the authors of this EPJ E paper have discovered a specific thermal process that makes it possible to change the column alignment from planar to vertical and achieve the best conditions for charge transport in photovoltaic devices.

EPJ E welcomes Daan Frenkel as new Editor in Chief, next to Richard Jones and Frank Jülicher. Daan Frenkel is a computational physicist who's research focuses on numerical exploration of routes to design novel, self-assembling structures and materials. Currently he is a professor at the universities of Cambridge, Amsterdam, Utrecht and Beijing. He is a foreign member of the British Royal Society and he has many received prestigious awards such as the Aneesur Rahman Prize of the APS, the Spinoza Prize of the Dutch Research Council and the Berni J. Alder CECAM Prize.

Athene Donald, Professor of Experimental Physics at the Cavendish Laboratory in Cambridge, has been nominated for her contribution to unravelling the mysteries of the physics of messy materials, ranging from cement to starch. Some of this work was published in the EPJ E. The former editor in chief of EPJ E (and current member of its advisory editorial board) will receive her prize on 5 March 2009, at UNESCO Headquarters in Paris. Since 1998, the L'ORÉAL-UNESCO Awards have distinguished 57 women from around the globe. Through their individual contributions to scientific research the Laureates have been agents for change and progress. We have no doubt that Athene Donald will take this award as a new opportunity to promote the work and dedication of female scientists and inspire them to excel.
