Bacteria are usually studied in well-mixed environments such as in shaken tubes or chemostats. However, bacteria often live on surfaces and migrate in space while they grow. The growth laws of such planar bacterial populations have been less studied. Here we employ a novel method for quantifying growth and gene expression in space and time and find that motile bacteria expand outward and continuously leave a portion of the population behind. The advancing bacteria grow and keep their density constant...

Small interfering RNAs (siRNAs) are used to decrease the production of specific proteins in cells and promise new types of therapies to treat tumors. The challenge is to design drug-delivery tools capable of specifically transporting siRNAs to cancer cells. This paper systematically explores a variety of nanocomplex designs and identifies key criteria that allow them to enter cells and release siRNA cargo.

Our paper highlights recent advances in the field of microfabricated encapsulating devices, emphasizing the development of emulsifying encapsulations, device design and current assays that are performed using encapsulating droplets on microfluidic chips.

The synthesis of a protein requires that the ribosome unwinds structures at the 5'-end of the messenger RNA to prevent inhibition of the translation initiation. Ribosomal protein S1 reversibly binds single-stranded RNA in steps of two or three nucleotides to uncover the site for ribosome binding and subsequent translation.

Just like the bones that support your body, your cells have their own scaffolding to hold them up. This scaffolding, known as the extracellular matrix or ECM, not just props up cells but also provides attachment sites, or “sticky spots”, to which cells can bind, just as bones hold muscles in place.

Our research has revealed distinct signaling pathways in the model plant Arabidopsis that control iron-deficiency responses and further highlights the complexity of the networks driving plant responses to low iron nutrition. Understanding how plants deal with iron deficiency is critical to human nutrition because vegetarian diets based on iron deprived crops may enforce anemia.

The formation of neuronal networks relies on the proper development and targeting of the neurons within. The actin cytoskeleton plays an important role during the process of axon guidance. The non-catalytic subunit of the Drosophila NatB complex, Psidin, is essential to maintain the actin cytoskeleton in a dynamic and responsive state. At the same time Psidin, together with the catalytic part of the NatB complex, is required for the survival of neurons.

A newly identified hearing organ in a South American bush cricket, which possesses one of the smallest ears known, shows insect hearing is so sophisticated that it rivals our own. The study, published in Science, is the first to identify a hearing mechanism in an insect that is evolutionarily convergent to those of mammals.

There are many examples of peptides that self-assemble to form long, fibrous structures. Forming closed assemblies is more difficult. This HFSP-funded study shows that two α-helical peptides can be joined by a series of peptide linkers of different lengths to form a range of new peptide assemblies. The structure formed depends on the length of the linker employed, with short linkers favoring fibers and the longer linkers leading to closed nanostructures.
