Many bacteria emit and sense small, diffusible 'signaling' molecules (autoinducers) whose extracellular concentration regulates gene expression through a positive feedback system, controlling important functions including virulence and biofilm formation. …

Of all the art historians who founded the discipline through their teaching and publications in the 19th century, Jacob Burckhardt (1818-1897) remains the only German-language author whose works - "Cicerone", "Renaissance Architecture in Italy" and …

Quantum systems which are discrete both in space and time can be realized with pseudo-spin-1⁄2 atoms stored in the spin-dependent optical lattice presented inlecture I: the quantum state evolves in a digital way through finite time steps, with spatial …

We have discovered a process, Silica Cell Replication , wherein mammalian cells direct their exact replication in silica . The silica cell replicas preserve nm-to macro-scale cellular features and dimensions on both the cell surface and interior after …

Both simple atoms and photons can be described by two quantum states only, e.g. two selected internal states for atoms, two polarization states for photons. In a new language, introduced over the past two decades, such objects are now considered carriers …
