Active mode of excretion across digestive tissues predates the origin of excretory organs
(Journal article; Peer reviewed, 2019)Most bilaterian animals excrete toxic metabolites through specialized organs, such as nephridia and kidneys, which share morphological and functional correspondences. In contrast, excretion in non-nephrozoans is largely ... -
AJAM-A–tetraspanin–αvβ5 integrin complex regulates contact inhibition of locomotion
(Journal article; Peer reviewed, 2022)Contact inhibition of locomotion (CIL) is a process that regulates cell motility upon collision with other cells. Improper regulation of CIL has been implicated in cancer cell dissemination. Here, we identify the cell ... -
Analysis of merged SMMR-SSMI time series of Arctic and Antarctic sea ice parameters 1978-1995
(Journal article; Peer reviewed, 1997-02-15)The most consistent means of investigating the global sea ice cover is by satellite passive microwave sensors, as these are independent of illumination and cloud cover. The Nimbus 7 Scanning Multichannel Microwave Radiometer ... -
An ancient FMRFamide-related peptide-receptor pair induces defense behavior in a brachiopod larva
(Journal article; Peer reviewed, 2017)Animal behaviour often comprises spatially separated sub-reactions and even ciliated larvae are able to coordinate sub-reactions of complex behaviours (metamorphosis, feeding). How these sub-reactions are coordinated is ... -
Ancora: a web resource for exploring highly conserved noncoding elements and their association with developmental regulatory genes
(Journal article; Peer reviewed, 2008-02-12)Metazoan genomes contain arrays of highly conserved noncoding elements (HCNEs) that span developmental regulatory genes and define regulatory domains. We describe Ancora http:// ancora.genereg.net, a web resource that ... -
Application of a hybrid EnKF-OI to ocean forecasting
(Journal article, 2009-10-01)Data assimilation methods often use an ensemble to represent the background error covariance. Two approaches are commonly used; a simple one with a static ensemble, or a more advanced one with a dynamic ensemble. The latter ... -
The architecture of cell differentiation in choanoflagellates and sponge choanocytes
(Journal article; Peer reviewed, 2019-04-12)Although collar cells are conserved across animals and their closest relatives, the choanoflagellates, little is known about their ancestry, their subcellular architecture, or how they differentiate. The choanoflagellate ... -
Arctic Sea level Budget Assessment During the GRACE/Argo Time Period
(Journal article; Peer reviewed, 2020)Sea level change is an important indicator of climate change. Our study focuses on the sea level budget assessment of the Arctic Ocean using: (1) the newly reprocessed satellite altimeter data with major changes in the ... -
Assembly and positioning of actomyosin rings by contractility and planar cell polarity
(Journal article; Peer reviewed, 2015-10-21)The actomyosin cytoskeleton is a primary force-generating mechanism in morphogenesis, thus a robust spatial control of cytoskeletal positioning is essential. In this report, we demonstrate that actomyosin contractility and ... -
Automated behavioural analysis reveals the basic behavioural repertoire of the urochordate Ciona intestinalis
(Journal article; Peer reviewed, 2019-02-20)Quantitative analysis of animal behaviour in model organisms is becoming an increasingly essential approach for tackling the great challenge of understanding how activity in the brain gives rise to behaviour. Here we used ... -
Barents Sea seasonal ice zone features and processes from ERS 1 synthetic aperture radar: Seasonal Ice Zone Experiment 1992
(Journal article; Peer reviewed, 1999-07-15)Sea ice features and processes in the Barents Sea were studied during the Seasonal Ice Zone Experiment 1992 (SIZEX92), a dedicated ERS 1 satellite synthetic aperture radar (SAR) field campaign carried out in March 1992. ... -
The Birth and Death of Toxins with Distinct Functions: A Case Study in the Sea Anemone Nematostella
(Journal article; Peer reviewed, 2019-05-27)The cnidarian Nematostella vectensis has become an established lab model, providing unique opportunities for venom evolution research. The Nematostella venom system is multimodal: involving both nematocytes and ectodermal ... -
Calcareous sponge genomes reveal complex evolution of α-carbonic anhydrases and two key biomineralization enzymes
(Journal article; Peer reviewed, 2014-11-25)Background: Calcium carbonate biominerals form often complex and beautiful skeletal elements, including coral exoskeletons and mollusc shells. Although the ability to generate these carbonate structures was apparently ... -
A cellular and molecular analysis of SoxB-driven neurogenesis in a cnidarian
(Journal article; Peer reviewed, 2022)Neurogenesis is the generation of neurons from stem cells, a process that is regulated by SoxB transcription factors (TFs) in many animals. Although the roles of these TFs are well understood in bilaterians, how their ... -
Characterization of Schistosoma mansoni Glutamate-Gated Chloride Channels
(Journal article; Peer reviewed, 2020)Electrophysiology is the standard method for characterizing ion channel function. Two-electrode voltage clamp is a robust and relatively simple version which can be applied to the characterization of glutamate-gated chloride ... -
Characterizing chaotic dispersion in a coastal tidal model
(Journal article, 2006-07-03)Diverse Lagrangian methods are used to study dispersion and mixing in a model in the Norwegian Trondheim fjord. We focus on the tidally driven currents, neglecting wind-forcing, and generate a large number of particle ... -
Choanoflagellates and the ancestry of neurosecretory vesicles
(Journal article; Peer reviewed, 2021)Neurosecretory vesicles are highly specialized trafficking organelles that store neurotransmitters that are released at presynaptic nerve endings and are, therefore, important for animal cell–cell signalling. Despite ... -
Chromatin jets define the properties of cohesin-driven in vivo loop extrusion
(Journal article; Peer reviewed, 2022)Complex genomes show intricate organization in three-dimensional (3D) nuclear space. Current models posit that cohesin extrudes loops to form self-interacting domains delimited by the DNA binding protein CTCF. Here, we ... -
Ciliary photoreceptors in the cerebral eyes of a protostome larva
(Peer reviewed; Journal article, 2011-03-01)Background: Eyes in bilaterian metazoans have been described as being composed of either ciliary or rhabdomeric photoreceptors. Phylogenetic distribution, as well as distinct morphologies and characteristic deployment of ... -
