The mitotic spindle is a highly dynamic molecular machine composed of tubulin, motors,
and other molecules. It assembles around the chromosomes and distributes the duplicated …

Over the past two decades, molecular and cell biologists have made important progress in
characterizing the components and compartments of the cell. New visualization methods …

A planetary-scale understanding of the ocean ecosystem, particularly in light of climate
change, is crucial. Here, we review the work of Tara Oceans, an international, multidisciplinary …

Microbes are dominant drivers of biogeochemical processes, yet drawing a global picture of
functional diversity, microbial community structure, and their ecological determinants …

Marine plankton support global biological and geochemical processes. Surveys of their
biodiversity have hitherto been geographically restricted and have not accounted for the full …

Functional nuclei and mitotic spindles are shown to assemble around DNA-coated beads
incubated in Xenopus egg extracts. Bipolar spindles assemble in the absence of centrosomes …

Species interaction networks are shaped by abiotic and biotic factors. Here, as part of the
Tara Oceans project, we studied the photic zone interactome using environmental factors and …

The small GTPase Ran, bound to GTP, is required for the induction of spindle formation by
chromosomes in M phase. High concentrations of Ran.GTP are proposed to surround M …

The biological carbon pump is the process by which CO 2 is transformed to organic carbon
via photosynthesis, exported through sinking particles, and finally sequestered in the deep …

… Draetta and E.Karsenti, in preparation). We assessed the ability of exogenous cdc25-C to
activate the cdc2-cyclin Bi complex in these extracts by measuring the cdc2 histone HI kinase …
