The question as to the origin and relationship between the three domains of life is lodged in a phylogenetic impasse. The dominant paradigm is to see the three domains as separated. However, the recently characterized bacterial species have suggested continuity between the three domains. Here, we review the evidence in support of this hypothesis and(More)
Life science research focuses on deciphering the biochemical mechanisms that regulate cell proliferation and function and largely depends on the use of tissue culture methods in which cells are grown on two-dimensional hard plastic or glass surfaces. However, the flat surface of the tissue culture plate represents a poor topological approximation of the(More)
Pavel Tomančák did his PhD at the European Molecular Biology Laboratory in the field of Drosophila developmental genetics. During his post-doctoral time at the University of California in Berkeley at the laboratory of Gerald M. Rubin, he established image-based genome scale resources for patterns of gene expression in Drosophila embryos. Since 2005 he leads(More)
The Tara Oceans expedition (2009-2013) sampled contrasting ecosystems of the world oceans, collecting environmental data and plankton, from viruses to metazoans, for later analysis using modern sequencing and state-of-the-art imaging technologies. It surveyed 210 ecosystems in 20 biogeographic provinces, collecting over 35,000 samples of seawater and(More)
BACKGROUND Phylogenetic analyses of protein families are used to define the evolutionary relationships between homologous proteins. The interpretation of protein-sequence phylogenetic trees requires the examination of the taxonomic properties of the species associated to those sequences. However, there is no online tool to facilitate this interpretation,(More)
Reconstructing the transition from a single compartment bacterium to a highly compartmentalized eukaryotic cell is one of the most studied problems of evolutionary cell biology. However, timing and details of the establishment of compartmentalization are unclear and difficult to assess. Here, we propose the use of molecular markers specific to cellular(More)
Coral reefs hosts nearly 25% of all marine species and provide food sources for half a billion people worldwide while only a very small percentage have been surveyed. Advances in technology and processing along with affordable underwater cameras and Internet availability gives us the possibility to provide tools and softwares to survey entire coral reefs.(More)
