Granular Rayleigh-Taylor Instability
A granular instability driven by gravity is studied experimentally and numerically. The instability arises as grains fall in a closed Hele-Shaw cell where a layer of dense granular material is positioned above a layer of air. The initially flat front defi

Preface
The “Traffic and Granular Flow ’07” conference was the seventh of a series of international conferences that started in 1995 in J¨ ulich (Germany). Since then, the conference took place in Duisburg (1997), Stuttgart (1999), Nagoya (2001), Delft (2003) and Berlin (2005). The aim of TGF conferences is to facilitate the exchanges between various fields dealing with transport. When the conference was created, the fields that were represented were road traffic and granular flow – hence the name of the series. Since then, the scope of the conference has been enlarged to include in particular collective motion in biology (molecular motors), a subject which turns out to have many connections with the two original ones. Transversal themes have emerged. For TGF07, a session was specifically devoted to the subject of networks. An important theme is also the one of self-propelled
