Tetrodotoxin-sensitive sodium channels mediate action potential firing and excitability in menthol-sensitive Vglut3-lineage sensory neurons
(Society for Neuroscience, 2019-09-04)Small-diameter vesicular glutamate transporter 3-lineage (Vglut3lineage) dorsal root ganglion (DRG) neurons play an important role in mechanosensation and thermal hypersensitivity; however, little is known about their ... -
Supporting Spartina: Interdisciplinary perspective shows spartina as a distinct solid genus
(Ecological Society of America, 2019-09-19)In 2014, a DNA‐based phylogenetic study confirming the paraphyly of the grass subtribe Sporobolinae proposed the creation of a large monophyletic genus Sporobolus, including (among others) species previously included in ... -
Nitrogen cycle patterns during forest regrowth in an African Miombo woodland landscape
(American Geophysical Union, 2019-05-08)Tropical dry forests in eastern and southern Africa cover 2.5 × 106 km2, support wildlife habitat and livelihoods of more than 150 million people, and face threats from land use and climate change. To inform conservation, ... -
The ventral epithelium of Trichoplax adhaerens deploys in distinct patterns cells that secrete digestive enzymes, mucus or diverse neuropeptides
(Company of Biologists, 2019-08-09)The disk-shaped millimeter-sized marine animal, Trichoplax adhaerens, is notable because of its small number of cell types and primitive mode of feeding. It glides on substrates propelled by beating cilia on its lower ... -
The Chlamydomonas flagellar membrane glycoprotein FMG-1B is necessary for expression of force at the flagellar surface
(Company of Biologists, 2019-08-19)In addition to bend propagation for swimming, Chlamydomonas cells use their flagella to glide along a surface. When polystyrene microspheres are added to cells, they attach to and move along the flagellar surface, thus ... -
Pectin chemistry and cellulose crystallinity govern pavement cell morphogenesis in a multi-step mechanism
(American Society of Plant Biologists, 2019-08-29)Simple plant cell morphologies, such as cylindrical shoot cells, are determined by the extensibility pattern of the primary cell wall, which is thought to be largely dominated by cellulose microfibrils, but the mechanism ... -
Future nitrogen availability and its effect on carbon sequestration in Northern Eurasia
(Nature Research, 2019-07-09)Nitrogen (N) availability exerts strong control on carbon storage in the forests of Northern Eurasia. Here, using a process-based model, we explore how three factors that alter N availability—permafrost degradation, ... -
Construction and composition of the squid pen from Doryteuthis pealeii
(University of Chicago Press, 2019-07-08)The pen, or gladius, of the squid is an internalized shell. It serves as a site of attachment for important muscle groups and as a protective barrier for the visceral organs. The pen’s durability and flexibility are derived ... -
A composition-dependent molecular clutch between T cell signaling condensates and actin
(eLife Sciences Publications, 2019-07-03)During T cell activation, biomolecular condensates form at the immunological synapse (IS) through multivalency-driven phase separation of LAT, Grb2, Sos1, SLP-76, Nck, and WASP. These condensates move radially at the IS, ... -
Hydrodynamics of vortex generation during bell contraction by the hydromedusa Eutonina indicans (Romanes, 1876).
(MDPI, 2019-07-05)Swimming bell kinematics and hydrodynamic wake structures were documented during multiple pulsation cycles of a Eutonina indicans (Romanes, 1876) medusa swimming in a predominantly linear path. Bell contractions produced ... -
Functional traits and spatio-temporal structure of a major group of soil protists (Rhizaria: Cercozoa) in a temperate grassland.
(Frontiers Media, 2019-06-11)Soil protists are increasingly appreciated as essential components of soil foodwebs; however, there is a dearth of information on the factors structuring their communities. Here we investigate the importance of different ... -
Framework for sustained climate assessment in the United States
(American Meteorological Society, 2019-06-04)As states, cities, tribes, and private interests cope with climate damages and seek to increase preparedness and resilience, they will need to navigate myriad choices and options available to them. Making these choices in ... -
Parkinson's disease protein DJ-1 regulates ATP synthase protein components to increase neuronal process outgrowth
(Springer Nature, 2019-06-13)Familial Parkinson’s disease (PD) protein DJ-1 mutations are linked to early onset PD. We have found that DJ-1 binds directly to the F1FO ATP synthase β subunit. DJ-1’s interaction with the β subunit decreased mitochondrial ... -
Single nucleosome imaging reveals loose genome chromatin networks via active RNA polymerase II.
(Rockefeller University Press, 2019-03-01)Although chromatin organization and dynamics play a critical role in gene transcription, how they interplay remains unclear. To approach this issue, we investigated genome-wide chromatin behavior under various transcriptional ... -
Evaluating knowledge to support climate action: A framework for sustained assessment. report of an independent advisory committee on applied climate assessment.
(American Meteorological Society, 2019-05-21)As states, cities, tribes, and private interests cope with climate damages and seek to increase preparedness and resilience, they will need to navigate myriad choices and options available to them. Making these choices in ... -
Xenopus resources: Transgenic, inbred and mutant animals, training opportunities, and web-based support.
(Frontiers Media, 2019-04-25)Two species of the clawed frog family, Xenopus laevis and X. tropicalis, are widely used as tools to investigate both normal and disease-state biochemistry, genetics, cell biology, and developmental biology. To support ... -
A ctenophore (comb jelly) employs vortex rebound dynamics and outperforms other gelatinous swimmers
(The Royal Society, 2019-03-20)Gelatinous zooplankton exhibit a wide range of propulsive swimming modes. One of the most energetically efficient is the rowing behaviour exhibited by many species of schyphomedusae, which employ vortex interactions to ... -
Seasonal and daily patterns of the mating calls of the oyster toadfish, Opsanus tau.
(University of Chicago Press, 2019-02-08)Acoustic communication is vital across many taxa for mating behavior, defense, and social interactions. Male oyster toadfish, Opsanus tau, produce courtship calls, or “boatwhistles,” characterized by an initial broadband ... -
Climate and lawn management interact to control C4 plant distribution in residential lawns across seven U.S. cities.
(Ecological Society of America, 2019-04-01)In natural grasslands, C4 plant dominance increases with growing season temperatures and reflects distinct differences in plant growth rates and water use efficiencies of C3 vs. C4 photosynthetic pathways. However, in ... -
Water salinity and inundation control soil carbon decomposition during salt marsh restoration: An incubation experiment.
(Wiley Open Access, 2019-02-10)Coastal wetlands are a significant carbon (C) sink since they store carbon in anoxic soils. This ecosystem service is impacted by hydrologic alteration and management of these coastal habitats. Efforts to restore tidal ...
