Spatial variability of Inherent Optical Properties in the perialpine lakes

Alfred Johny Wüest, Damien Bouffard, Vincent Maurice Nouchi

Accurate estimation of biogeochemical substances from remote observations requires knowledge of Inherent Optical Properties (IOPs) and their mass specific representation (SIOPs). Corresponding measurements are rather scarce for perialpine lakes, which repr ...

Timing by rhythms: Daily clocks and developmental rulers

Andrew Charles Oates

Biological rhythms are widespread, allowing organisms to temporally organize their behavior and metabolism in advantageous ways. Such proper timing of molecular and cellular events is critical to their development and health. This is best understood in the ...

Protocols for Visualizing Horizontal Gene Transfer in Gram-Negative Bacteria Through Natural Competence

Melanie Blokesch

Horizontal gene transfer (HGT) is widespread in bacteria and archaea and plays a significant role in prokaryotic evolution. One mode of HGT is natural competence for genetic transformation, which allows the organism to take up free DNA from its surrounding ...

Computational studies on Escherichia coli metabolism

Stefano Andreozzi

Metabolic Engineering is fostered by an increasing effort and progress in the collection of large and accurate 'omics' datasets. The abundance of available measurements and advances in measurement techniques only alleviate to a certain extent the uncertai ...

Leben und sterben lassen – horizontaler Gentransfer in Vibrio cholerae

Melanie Blokesch

There is a fundamental gap in our understanding of how horizontal gene transfer contributes to the enormous range of genetic variations that are observed among bacteria. Our model organism is Vibrio cholerae, the causative agent of cholera. V. cholerae ent ...

Equilibrium concentration of singlet oxygen in photoreaction of reaction center/carbon nanotube bionanocomposites

László Forró, Arnaud Magrez, Endre Horvath, Klara Hernadi

The reaction center protein is the unit in the photosynthetic organisms in which the primary events of the photoelectric energy conversion take place during photosynthesis. When the photochemistry following the excitation of the reaction center by light is ...

Cellular hallmarks reveal restricted aerobic metabolism at thermal limits

Pierre Gönczy, Coralie Busso, Aitana Neves da Silva

All organisms live within a given thermal range, but little is known about the mechanisms setting the limits of this range. We uncovered cellular features exhibiting signature changes at thermal limits in Caenorhabditis elegans embryos. These included chan ...

Capturing Cell-Cell Interactions via SNAP-tag and CLIP-tag Technology

Matthias Lütolf

Juxtacrine or contact-dependent signaling is a major form of cell communication in multicellular organisms. The involved cell-cell and cell-extracellular-matrix (ECM) interactions are crucial for the organization and maintenance of tissue architecture and ...

Merging microfluidics and micro-array concepts: from molecular to nematode-based bioassays

Matteo Cornaglia

Essential in biomedical research is the necessity of gathering statistically relevant data about large populations of specific biological entities, e.g. organisms, cells or molecules, while preserving detailed information about each single entity under in ...

Tetracycline Antibiotics Impair Mitochondrial Function and Its Experimental Use Confounds Research

Johan Auwerx, Laurent Mouchiroud, Richardus Houtkooper

Tetracyclines, a class of antibiotics that target bacterial translation, are commonly used in research for inducible gene expression using Tet-ON/Tet-OFF systems. However, such tetracycline-inducible systems carry a risk. Given that mitochondria have a "ba ...
