Sensing mechanical forces is key to cardiovascular development but the mechanism explaining how endothelial cells sense flow forces remains unclear. The aim of this study was to address the mechanism of endothelial cell mechanotransduction through primary cilia by implementing live and high-resolution imaging of endothelial cilia during zebrafish vascular development.

Sleep is under homeostatic control, but the neural mechanisms that sense the need to sleep remain poorly understood. We have found that a small cluster of sleep-promoting neurons in the fly brain becomes more excitable after extended waking to allow the brain to regain lost sleep and restore neural functioning.

Studying the development of embryonic tissues at a cellular resolution, resolving clonal relationships among the cells in an organ, will help to understand the formation of the different organs in normal and pathological conditions. Whereas there are already several methods to label clones available, they all have drawbacks and could suffer from either underestimating or overestimating the size of the clones. To minimize such mistakes, very few clones must be studied in a given specimen, impeding...

Because of high functional demands, tissue size is tightly regulated during development. This is particularly evident in limb length, where differences in size between matching limbs could have significant impacts on fitness. Although right and left sides of the body develop independently, right and left limbs consistently reach comparable length (Allard & Tabin 2009). Similarly, size differences in the right and left sides of the jaw are involved in many craniofacial malformations, such as...

By generating various Drosophila lines with two mitochondrial genotypes, we show that purifying selection drove complete replacement of the deleterious mutations by a wild type genome, but selection can stabilize propagation of two defective genomes that are complementary. Interestingly, such a selection does not occur at the organismal level, but rather occurs during a confined stage of oogenesis, likely due to a preferential proliferation advantage of the co-existing genome, which is more functional...

It is proposed that MicroRNAs regulate the expression of many target genes, suggesting they act as master regulators of the genome. We found that the Cnidarian Nematostella vectensis expresses dozens of different microRNAs (contradicting previous claims linking the number of microRNA genes to a poorly-defined "organism complexity") and we saw that Cnidarian microRNAs frequently direct endonucleolytic cleavage of their RNA targets, similarly to what is observed in plants.

Methods to reversibly regulate protein levels in cells are valuable for researchers in life science. A technology to induce degradation of a protein of interest by blue light has been developed and applied in cells and zebrafish embryos.

Fundamental unresolved problems of motor coding and sensorimotor integration include what information about behavior is represented at different levels of the motor pathway. An interdisciplinary collaboration integrating physical, acoustic, and biological approaches validated a dynamical systems model for birdsong production and proposed a novel frame for understanding neural coding in zebra finches.

MAP65 family proteins function as microtubule cross-linking proteins, and localise to the phragmoplast equator in the moss Physcomitrella patens (phragmoplast is a microtubule-based bipolar structure that appeared at the late stage of mitosis in plant cells). RNAi-mediated knockdown of MAP65s compromised microtubule bipolarity and affected accumulation and/or fusion of cell plate–destined vesicles at the equatorial plane.

Everybody is talking about interdisciplinarity these days but how do we provoke it? In the current issue of the journal eLife, our HFSP funded Young Investigator team describes a computational speed-dating approach that we developed to purposely ‘engineer’ such interactions amongst participants in small scientific conferences which we successfully prototyped at a Royal Society Scientific Discussion Meeting, organized by means of our HFSP collaboration.
