Colloid osmotic parameterization and measurement of subcellular crowding
(American Society for Cell Biology, 2019-01-14)Crowding of the subcellular environment by macromolecules is thought to promote protein aggregation and phase separation. A challenge is how to parameterize the degree of crowding of the cell interior or artificial solutions ... -
Localizing individual soniferous fish using passive acoustic monitoring
(Elsevier, 2018-08-13)Identifying where fish inhabit is a fundamentally important topic in ecology and management allowing acoustically sensitive times and areas to be prioritized. Passive acoustic localization has the benefit of being a ... -
Propulsive design principles in a multi-jet siphonophore.
(Company of Biologists, 2019-02-27)Coordination of multiple propulsors can provide performance benefits in swimming organisms. Siphonophores are marine colonial organisms that orchestrate the motion of multiple swimming zooids for effective swimming. However, ... -
Drosophila kinesin-8 stabilizes the kinetochore–microtubule interaction
(Rockefeller University Press, 2018-12-11)Kinesin-8 is required for proper chromosome alignment in a variety of animal and yeast cell types. However, it is unclear how this motor protein family controls chromosome alignment, as multiple biochemical activities, ... -
Elaborate pupils in skates may help camouflage the eye
(Company of Biologists, 2019-01-21)The skate Leucoraja erinacea is a bottom-dweller that buries into the substrate with its eyes protruding, revealing elaborately shaped pupils. It has been suggested that such pupil shapes may camouflage the eye, yet this ... -
An amphipathic helix enables septins to sense micrometer-scale membrane curvature
(Rockefeller University Press, 2019-01-18)Cell shape is well described by membrane curvature. Septins are filament-forming, GTP-binding proteins that assemble on positive, micrometer-scale curvatures. Here, we examine the molecular basis of curvature sensing by ... -
A versatile and open-source rapid LED switching system for one-photon imaging and photo-activation
(Frontiers Media, 2019-01-17)Combining fluorescence and transmitted light sources for microscopy is an invaluable method in cellular neuroscience to probe the molecular and cellular mechanisms of cells. This approach enables the targeted recording ... -
Lateral line sensitivity in free-swimming toadfish Opsanus tau
(Company of Biologists, 2019-01-25)A longstanding question in aquatic animal sensory physiology is the impact of self-generated movement on lateral line sensitivity. One hypothesis is that efferent modulation of the sensory hair cells cancels self-generated ... -
Regenerative capacity in the lamprey spinal cord is not altered after a repeated transection
(Public Library of Science, 2019-01-30)The resilience of regeneration in vertebrates is not very well understood. Yet understanding if tissues can regenerate after repeated insults, and identifying limitations, is important for elucidating the underlying ... -
Effect of continuous light on leaf wax isotope ratios in Betula nana and Eriophorum vaginatum: Implications for Arctic paleoclimate reconstructions
(Elsevier B.V., 2018-08-22)Reconstructions of climate using leaf wax D/H ratios (δDwax) require accounting for the apparent isotopic fractionation (εapp) between plant source water and waxes. There have been conflicting publications on whether plants ... -
Neuronal morphologies built for reliable physiology in a rhythmic motor circuit
(eLife Sciences Publications, 2019-01-18)It is often assumed that highly-branched neuronal structures perform compartmentalized computations. However, previously we showed that the Gastric Mill (GM) neuron in the crustacean stomatogastric ganglion (STG) operates ... -
Improvements in simultaneous sodium and calcium imaging
(2019-01-08)High speed imaging of ion concentration changes in neurons is an important and growing tool for neuroscientists. We previously developed a system for simultaneously measuring sodium and calcium changes in small compartments ... -
Ocean deoxygenation and zooplankton: Very small oxygen differences matter
(American Association for the Advancement of Science, 2018-12-19)Oxygen minimum zones (OMZs), large midwater regions of very low oxygen, are expected to expand as a result of climate change. While oxygen is known to be important in structuring midwater ecosystems, a precise and mechanistic ... -
A size-invariant bud-duration timer enables robustness in yeast cell size control
(2018-12-21)Cell populations across nearly all forms of life generally maintain a characteristic cell type-dependent size, but how size control is achieved has been a long-standing question. The G1/S boundary of the cell cycle serves ... -
Contributions of photosynthetic organs to the seed yield of hybrid rice: The effects of gibberellin application examined by carbon isotope technology
(Zheng et al., 2018-12-01)Changes in the structure and quality of a hybrid combination population have been observed after the application of gibberellins. Such changes would affect the accumulation and distribution of photosynthetic products, which ... -
Vegetation indices do not capture forest cover variation in Upland Siberian Larch Forests
(MDPI AG, Basel, Switzerland, 2018-10-25)Boreal forests are changing in response to climate, with potentially important feedbacks to regional and global climate through altered carbon cycle and albedo dynamics. These feedback processes will be affected by vegetation ... -
The Bermuda Triangle : the pragmatics, policies, and principles for data sharing in the history of the Human Genome Project
(Springer, 2018-11-02)The Bermuda Principles for DNA sequence data sharing are an enduring legacy of the Human Genome Project (HGP). They were adopted by the HGP at a strategy meeting in Bermuda in February of 1996 and implemented in formal ... -
Two forms of electrical transmission between neurons
(Frontiers Media, 2018-11-21)Electrical signaling is a cardinal feature of the nervous system and endows it with the capability of quickly reacting to changes in the environment. Although synaptic communication between nerve cells is perceived to be ... -
Stable isotopic evidence of nitrogen sources and C4 metabolism driving the world’s largest macroalgal green tides in the Yellow Sea
(Nature Publishing Group, 2018-11-28)During recent years, rapid seasonal growth of macroalgae covered extensive areas within the Yellow Sea, developing the world’s most spatially extensive “green tide”. The remarkably fast accumulation of macroalgal biomass ... -
Environmental controls, emergent scaling, and predictions of greenhouse gas (GHG) fluxes in coastal salt marshes
(John Wiley & Sons, 2018-07-28)Coastal salt marshes play an important role in mitigating global warming by removing atmospheric carbon at a high rate. We investigated the environmental controls and emergent scaling of major greenhouse gas (GHG) fluxes ...
