Embryonic origin and serial homology of gill arches and paired fins in the skate, Leucoraja erinacea
(eLife Sciences Publications, 2020-11-17)Paired fins are a defining feature of the jawed vertebrate body plan, but their evolutionary origin remains unresolved. Gegenbaur proposed that paired fins evolved as gill arch serial homologues, but this hypothesis is now ... -
Phytoplankton temporal strategies increase entropy production in a marine food web model
(MDPI, 2020-11-03)We develop a trait-based model founded on the hypothesis that biological systems evolve and organize to maximize entropy production by dissipating chemical and electromagnetic free energy over longer time scales than abiotic ... -
Field testing of biohybrid robotic jellyfish to demonstrate enhanced swimming speeds
(MDPI, 2020-11-21)Biohybrid robotic designs incorporating live animals and self-contained microelectronic systems can leverage the animals’ own metabolism to reduce power constraints and act as natural chassis and actuators with damage ... -
Octopus arms exhibit exceptional flexibility
(Nature Research, 2020-11-30)The octopus arm is often referred to as one of the most flexible limbs in nature, yet this assumption requires detailed inspection given that this has not been measured comprehensively for all portions of each arm. We ... -
Interannual, summer, and diel variability of CH4 and CO2 effluxes from Toolik Lake, Alaska, during the ice-free periods 2010-2015
(Royal Society of Chemistry, 2020-07-09)Accelerated warming in the Arctic has led to concern regarding the amount of carbon emission potential from Arctic water bodies. Yet, aquatic carbon dioxide (CO2) and methane (CH4) flux measurements remain scarce, particularly ... -
Recovery of burrowing behavior after spinal cord injury in the larval sea lamprey
(University of Chicago Press, 2020-10-27)Following traumatic spinal cord injury, most mammalian species are unable to achieve substantial neuronal regeneration and often experience loss of locomotor function. In contrast, larval sea lampreys (Petromyzon marinus) ... -
A frog with three sex chromosomes that co-mingle together in nature: Xenopus tropicalis has a degenerate W and a Y that evolved from a Z chromosome
(Public Library of Science, 2020-11-09)In many species, sexual differentiation is a vital prelude to reproduction, and disruption of this process can have severe fitness effects, including sterility. It is thus interesting that genetic systems governing sexual ... -
Buzzards Bay Water Quality Data from the Buzzards Bay Coalition’s Baywatchers Program 1992-2018 December 2020 version
(Woods Hole Oceanographic Institution, 2020-12-08)The Buzzards Bay Coalition’s Baywatchers Monitoring Program collected summertime water quality information at more than 150 stations around Buzzards Bay, Massachusetts from 1992 to 2018. Baywatchers monitoring data document ... -
ESCargo: a regulatable fluorescent secretory cargo for diverse model organisms
(American Society for Cell Biology, 2020-10-28)Membrane traffic can be studied by imaging a cargo protein as it transits the secretory pathway. The best tools for this purpose initially block export of the secretory cargo from the endoplasmic ... -
The role of suction thrust in the metachronal paddles of swimming invertebrates
(Nature Research, 2020-10-20)An abundance of swimming animals have converged upon a common swimming strategy using multiple propulsors coordinated as metachronal waves. The shared kinematics suggest that even morphologically and systematically diverse ... -
Sox17 and ß-catenin co-occupy Wnt-responsive enhancers to govern the endoderm gene regulatory network
(eLife Sciences Publications, 2020-09-07)Lineage specification is governed by gene regulatory networks (GRNs) that integrate the activity of signaling effectors and transcription factors (TFs) on enhancers. Sox17 is a key transcriptional regulator of definitive ... -
The hierarchical assembly of septins revealed by high-speed AFM
(Nature Research, 2020-10-08)Septins are GTP-binding proteins involved in diverse cellular processes including division and membrane remodeling. Septins form linear, palindromic heteromeric complexes that can assemble in filaments and higher-order ... -
A pushing mechanism for microtubule aster positioning in a large cell type
(Cell Press, 2020-10-06)After fertilization, microtubule (MT) sperm asters undergo long-range migration to accurately position pronuclei. Due to the large sizes of zygotes, the forces driving aster migration are considered to be from pulling on ... -
Role of C4 carbon fixation in Ulva prolifera, the macroalga responsible for the world's largest green tides
(Nature Research, 2020-09-07)Most marine algae preferentially assimilate CO2 via the Calvin-Benson Cycle (C3) and catalyze HCO3− dehydration via carbonic anhydrase (CA) as a CO2-compensatory mechanism, but certain species utilize the Hatch-Slack Cycle ... -
Editorial: role of protein palmitoylation in synaptic plasticity and neuronal differentiation
(Frontiers Media, 2020-07-09)Protein palmitoylation, the reversible addition of palmitate to proteins, is a dynamic post-translational modification. Both membrane (e.g., channels, transporters, and receptors) and cytoplasmic proteins (e.g., cell ... -
CRISPR/Cas9 mediated mutation of the mtnr1a melatonin receptor gene causes rod photoreceptor degeneration in developing Xenopus tropicalis
(Nature Research, 2020-08-13)Nighttime surges in melatonin levels activate melatonin receptors, which synchronize cellular activities with the natural light/dark cycle. Melatonin receptors are expressed in several cell types in the retina, including ... -
Maximizing CRISPR/Cas9 phenotype penetrance applying predictive modeling of editing outcomes in Xenopus and zebrafish embryos
(Nature Research, 2020-09-04)CRISPR/Cas9 genome editing has revolutionized functional genomics in vertebrates. However, CRISPR/Cas9 edited F0 animals too often demonstrate variable phenotypic penetrance due to the mosaic nature of editing outcomes ... -
Spatial heterogeneity of the cytosol revealed by machine learning-based 3D particle tracking
(American Society for Cell Biology, 2020-06-29)The spatial structure and physical properties of the cytosol are not well understood. Measurements of the material state of the cytosol are challenging due to its spatial and temporal heterogeneity. Recent development of ... -
