They lack eyes to see and ears to hear but sense their microenvironment by adhering and physically deforming, which allows cells to feel into the depths of a matrix. To address how deeply cells feel we cultured mesenchymal stem cells, as prototypical but particularly sensitive adhesive cells, on collagen-coated gels-made microfilms of controlled elasticity (E) and thickness (h). After just 36 hrs in culture, cell spread area was distinctively smaller on thick and soft compared to either thin or stiff films, correlating well with nuclei morphology. Transition from small-to-large spread area transition was obtained at -

Su...» Hydrophobic surfaces are common in nature and technology. Surfactant monolayers are a standard method of hydrophobizing surfaces, and interactions between such monolayer-coated surfaces have been measured directly for decades: but they are not well understood. One frequent but puzzling observation is that of long-ranged (up to 100 nm) attractions between such surfaces across water, which are orders of magnitude larger than van der Waals forces. This was long attributed to water structuring near the hydrophobic surfaces, but such structuring is unlikely to exceed some nanometers at most. We now elucidate the origin of these long-ranged attractions, which resides in a subtle and counterintuitive electrostatic effect, even between overall neutral surfaces. -

The development of the new approach to science was a gradual process that owes much debt to the intellectuals who studied and worked in the Italian peninsula. At times, they chose to manifest their opinions through visual means, in the architecture and decoration of their private households. The lecture will present the case of a noble Venetian family, the Barbaro, whose villa decoration reveals a particularly detailed and practical level of scientific interest in Astronomy. The central theme of the mural paintings is a representation of an important solar eclipse that occurred in the sixteenth century, a discovery that was obtained through traditional methods of art history research combined with the use of modern Planetarium computer software. -

I discuss black hole entropy and its extension into a local current, in GR and in higher-curvature theories. I propose a tentative, non-statistical interpretation of black hole entropy. I discuss its relation to the usual interpretation by analogy with the role of charge currents in the fluid/gravity duality.

We are investigating any links between O-GlcNAcylation, cancer-specific metabolism, and survival in human cancers. To enable our studies, we have developed chemical tools to robustly visualize, identify, and manipulate O-GlcNAcylation in living cells. In this presentation, I will describe the development and characterization of a metabolic chemical reporter of O-GlcNAc modification created in our laboratory, the subsequent identification of 374 potentially O-GlcNAc modified proteins from mammalian cells, and our efforts to understand O-GlcNAc modification of the ubiquitin ligase NEDD4. -

Ion-conducting materials with quite different kinds of disordered structures have been found to show an unexpected degree of similarity in their broadband conductivity spectra. In particular, two surprising "universalities" have been detected. One of them, the "first universality", is a fingerprint of activated hopping along interconnected sites, while the other, the "second universality", reflects non-activated, strictly localised movements of the ions. The former is observed at sufficiently high temperatures, while the other is found at sufficiently low ones, e.g., in the cryogenic temperature regime. In either case, rate equations have been found that reproduce the relevant time dependence of the ion dynamics as well as the spectra themselves. Therefore, these equations may be regarded as manifestations of the underlying common laws. At the same time, they also form a sound basis for understanding and visualising the phenomena in terms of simple physical pictures.

"Energy transport and conversion at the nano-Scale"

One of the most promising and fascinating channels for achieving these goals is the use of nano-scale junctions for energy conversion, for example by utilizing thermo-electric effects. Understanding the processes that affect the energy transport and conversion at the nano-scale are thus a necessary mile-stone, and form a great challenge, both experimentally and theoretically. In this talk I review some recent advances in the theory of energy transport and conversion in nano-junctions. I describe several novel theories which have been developed for studying thermo-electric effects in nano-junctions, temperature distributions, energy transport in DNA nano-junctions, and energy to magnetization current conversion. These theories can be used to study basic physical phenomena (for instance local temperature fluctuations, the onset of Fourier’s law, DNA denaturation etc.) and can also lead to novel concepts and devices for energy transport and conversion such as thermal switches and thermal diodes.
