Ink release and swimming behavior in the oceanic Ctenophore Eurhamphaea vexilligera
(University of Chicago Press, 2020-06-08)Of the more than 150 ctenophore species, the oceanic ctenophore Eurhamphaea vexilligera is notable for its bright orange-yellow ink, secreted from numerous small vesicles that line its substomodeal comb rows. To date, in ... -
Shared up-regulation and contrasting down-regulation of gene expression distinguish desiccation-tolerant from intolerant green algae
(National Academy of Sciences, 2020-07-21)Among green plants, desiccation tolerance is common in seeds and spores but rare in leaves and other vegetative green tissues. Over the last two decades, genes have been identified whose expression is induced by desiccation ... -
α-Synuclein-112 impairs synaptic vesicle recycling consistent with its enhanced membrane binding properties
(Frontiers Media, 2020-05-29)Synucleinopathies are neurological disorders associated with α-synuclein overexpression and aggregation. While it is well-established that overexpression of wild type α-synuclein (α-syn-140) leads to cellular toxicity and ... -
Far-field unlabeled super-resolution imaging with superoscillatory illumination
(AIP Publishing, 2020-06-19)Unlabeled super-resolution is the next grand challenge in imaging. Stimulated emission depletion and single-molecule microscopies have revolutionized the life sciences but are still limited by the need for reporters (labels) ... -
Long-term imaging of the photosensitive, reef-building coral Acropora muricata using light-sheet illumination
(Nature Research, 2020-06-25)Coral reefs are in alarming decline due to climate emergency, pollution and other man-made disturbances. The numerous ecosystem services derived from coral reefs are underpinned by the growth and physical complexity of ... -
A demographic and evolutionary analysis of maternal effect senescence
(National Academy of Sciences, 2020-06-29)Maternal effect senescence—a decline in offspring survival or fertility with maternal age—has been demonstrated in many taxa, including humans. Despite decades of phenotypic studies, questions remain about how maternal ... -
Phosphoregulation provides specificity to biomolecular condensates in the cell cycle and cell polarity
(Rockefeller University Press, 2020-07-06)Biomolecular condensation is a way of organizing cytosol in which proteins and nucleic acids coassemble into compartments. In the multinucleate filamentous fungus Ashbya gossypii, the RNA-binding protein Whi3 regulates the ... -
Enhanced carbon uptake and reduced methane emissions in a newly restored wetland
(American Geophysical Union, 2020-01-04)Wetlands play an important role in reducing global warming potential in response to global climate change. Unfortunately, due to the effects of human disturbance and natural erosion, wetlands are facing global extinction. ... -
Long-term reliability of the figaro TGS 2600 solid-state methane sensor under low-Arctic conditions at Toolik Lake, Alaska
(European Geosciences Union, 2020-05-27)The TGS 2600 was the first low-cost solid-state sensor that shows a response to ambient levels of CH4 (e.g., range ≈1.8–2.7 µmol mol−1). Here we present an empirical function to correct the TGS 2600 signal for temperature ... -
Decreased soil organic matter in a long-term soil warming experiment lowers soil water holding capacity and affects soil thermal and hydrological buffering
(American Geophysical Union, 2020-04-04)Long‐term soil warming can decrease soil organic matter (SOM), resulting in self‐reinforcing feedback to the global climate system. We investigated additional consequences of SOM reduction for soil water holding capacity ... -
Comparative transcriptomics of an arctic foundation species, tussock cottongrass (Eriophorum vaginatum), during an extreme heat event
(Nature Research, 2020-06-02)Tussock cottongrass (Eriophorum vaginatum) is a foundation species for much of the arctic moist acidic tundra, which is currently experiencing extreme effects of climate change. The Arctic is facing higher summer temperatures ... -
The effect of bacteria on planula-larvae settlement and metamorphosis in the octocoral Rhytisma fulvum fulvum
(Public Library of Science, 2019-09-30)While increasing evidence supports a key role of bacteria in coral larvae settlement and development, the relative importance of environmentally-acquired versus vertically-transferred bacterial population is not clear. ... -
Intron and gene size expansion during nervous system evolution
(BMC, 2020-05-14)Background The evolutionary radiation of animals was accompanied by extensive expansion of gene and genome sizes, increased isoform diversity, and complexity of regulation. Results Here we show that the longest genes ... -
Adult chondrogenesis and spontaneous cartilage repair in the skate, Leucoraja erinacea
(eLife Sciences Publications, 2020-05-12)Mammalian articular cartilage is an avascular tissue with poor capacity for spontaneous repair. Here, we show that embryonic development of cartilage in the skate (Leucoraja erinacea) mirrors that of mammals, with developing ... -
Dynamics and functional diversity of the smallest phytoplankton on the Northeast US shelf
(National Academy of Sciences, 2020-05-15)Picophytoplankton are the most abundant primary producers in the ocean. Knowledge of their community dynamics is key to understanding their role in marine food webs and global biogeochemical cycles. To this end, we analyzed ... -
Wound healing across the animal kingdom: Crosstalk between the immune system and the extracellular matrix
(Wiley, 2020-04-20)Tissue regeneration is widespread in the animal kingdom. To date, key roles for different molecular and cellular programs in regeneration have been described, but the ultimate blueprint for this talent remains elusive. In ... -
Differences in intrinsic tubulin dynamic properties contribute to spindle length control in Xenopus species
(Elsevier, 2020-06-08)The function of cellular organelles relates not only to their molecular composition but also to their size. However, how the size of dynamic mesoscale structures is established and maintained remains poorly understood [1, ... -
Contribution of increasing plasma membrane to the energetic cost of early zebrafish embryogenesis
(American Society for Cell Biology, 2020-03-19)How do early embryos allocate the resources stored in the sperm and egg? Recently, we established isothermal calorimetry to measure heat dissipation by living zebrafish embryos and to estimate the energetics of specific ... -
Hydrocarbon seepage in the deep seabed links subsurface and seafloor biospheres
(National Academy of Sciences, 2020-04-30)Marine cold seeps transmit fluids between the subseafloor and seafloor biospheres through upward migration of hydrocarbons that originate in deep sediment layers. It remains unclear how geofluids influence the composition ... -
