We use confocal microscopy to directly visualize the dynamics of ageing colloidal glasses. We prepare a colloidal suspension at high density, a simple model system that shares many properties with… (More)
We study concentrated colloidal suspensions, a model system which has a glass transition. Samples in the glassy state show aging, in that the motion of the colloidal particles slows as the sample… (More)
HP never shied away from big names for its computers. There are high-performance servers named Apollo and optimized computing systems called Moonshot. And then there's The Machine. When… (More)

We study concentrated colloidal suspensions, a model system which has a glass transition. The non-equilibrium nature of the glassy state is most clearly highlighted by aging – the dependence of the… (More)
The latest analysis from the US National Science Board confirms that Israel leads the world in its economic devotion to research and development (R&D). Its civilian R&D spending in 2005 accounted for… (More)
Modern medicine offers a multitude of ways to go bionic. Today's implanted electrical devices can stimulate the nervous system, restore the senses, deliver drugs, and may soon replace entire organs.… (More)
