Scaling body size fluctuations

Andrea Rinaldo, Andrea Giometto, Francesco Carrara, Amos Maritan, Florian Altermatt

The size of an organism matters for its metabolic, growth, mortality, and other vital rates. Scale-free community size spectra (i.e., size distributions regardless of species) are routinely observed in natural ecosystems and are the product of intra- and i ...

In situ structural analysis of the Yersinia enterocolitica injectisome

Henning Paul-Julius Stahlberg, Matteo Dal Peraro, Marco Stenta, Matteo Thomas Degiacomi

Injectisomes are multi-protein transmembrane machines allowing pathogenic bacteria to inject effector proteins into eukaryotic host cells, a process called type III secretion. Here we present the first three-dimensional structure of Yersinia enterocolitica ...

iSLIM: a comprehensive approach to mapping and characterizing gene regulatory networks

Bart Deplancke, Sebastian Maerkl, Marcel Geertz, Sylvie Rockel

Mapping gene regulatory networks is a significant challenge in systems biology, yet only a few methods are currently capable of systems-level identification of transcription factors (TFs) that bind a specific regulatory element. We developed a microfluidic ...

The biofilm granulation mechanisms depend on the predominant populations involved

Christof Holliger, David Gregory Weissbrodt, Samuel Lochmatter

The novel aerobic granular sludge technology is attractive for intensified biological nutrient removal from wastewater. This process is based on self-granulated flocs forming fast-settling mobile biofilms with a gel-like consistence, called “granules”. Mec ...

Nonlinear Mode-Coupling in Nanomechanical Systems

Luis Guillermo Villanueva Torrijo

Understanding and controlling nonlinear coupling between vibrational modes is critical for the development of advanced nanomechanical devices; it has important implications for applications ranging from quantitative sensing to fundamental research. However ...

X-ray mosaic nanotomography of large microorganisms

Marco Stampanoni

Full-field X-ray microscopy is a valuable tool for 3D observation of biological systems. In the soft X-ray domain organelles can be visualized in individual cells while hard X-ray microscopes excel in imaging of larger complex biological tissue. The field ...

Highly Diverse and Seasonally Dynamic Protist Community in a Pristine Peat Bog

Edward Mitchell, Enrique Lara

Culture-independent molecular methods based on the amplification, cloning and sequencing of small-subunit ribosomal RNA genes (SSU rDNAs) are powerful tools to study the diversity of microorganisms. Despite so, the eukaryotic microbial diversity of many ec ...

Contributions to the modeling and design of reconfigurable reflecting cells embedding discrete control elements

Juan Ramon Mosig, Frédéric Bongard, Julien Perruisseau-Carrier, Roberto Torres Sánchez, Ruzica Golubovic

This paper presents new contributions to the modeling and design of reflecting cells embedding discrete control elements such as microelectromechanical system (MEMS) or diodes. First, a rigorous assessment of the different possibilities to simulate and mea ...

Interplay of DNA supercoiling and catenation during the segregation of sister duplexes

Andrzej Stasiak, Guillaume Witz, Pablo Hernandez

The discrete regulation of supercoiling, catenation and knotting by DNA topoisomerases is well documented both in vivo and in vitro, but the interplay between them is still poorly understood. Here we studied DNA catenanes of bacterial plasmids arising as a ...

Cyanobacterial Natural Products for the Inhibition of Biofilm Formation and Biofouling

Karl Gademann

Biofouling is defined by the non-specific attachment of biological material (proteins, carbohydrates, prokaryotic cells and higher organisms) to surfaces upon their exposure to any biological fluid. Biofouling is a serious problem in many areas ranging fro ...
