title: Data From: Effects of species and sex on the gut microbiome of four laboratory-reared fruit fly lines (Diptera: Tephritidae) using full-length 16S rRNA PacBio Kinnex sequencing

description: Species- and sex-related differences of four laboratory tephritid fruit fly (Diptera: Tephritidae) gut microbiomes evaluated with full-length 16S rRNA PacBio Kinnex sequencing. Insect gut microbiomes are shaped by multiple endogenous and environmental factors. Our study evaluated the impacts of how host sex and species influence the microbiome in laboratory-reared tephritids fruit flies when controlled for location, time, and adult diet. We evaluated the gut microbiome of four lines of pest tephritid fruit fly adults (<i>Bactrocera dorsalis, Bactrocera latifrons, Ceratitis capitata, Zeugodacus cucurbitae</i>) using near full-length 16S rRNA sequencing with a PacBio Kinnex concatenation-based approach. We analyzed groups of males and females from each species at the same set of time, across four timepoints in a core insectary. Results demonstrate a clear impact of fruit fly species on the gut microbiome composition of the different fruit flies. Furthermore, for <i>B. dorsalis, B. latifrons, </i>and <i>C. capitata</i>, we saw an influence of sex on amplicon sequence variant (ASV) composition. However, while there was a separation of samples between the sexes for each timepoint, there was no characteristic male or female microbiome in all cases.Dataset includes ASV count, taxonomy, fasta files, metadata, and R scripts. Raw sequence data has been deposited to the National Center for Biotechnology Information Sequence Read Archive (NCBI SRA) under the accession number PRJNA1196954.

title: High-Precision Relativistic Time Scales for Cislunar Navigation

description: We present a unified post-Newtonian framework for relativistic timing and coordinate transformations in the solar-system barycentric (TCB), geocentric (TCG/TT) and newly defined lunicentric (TCL/TL) reference systems. Extending the IAU BCRS/GCRS conventions, we construct a Lunicentric Celestial Reference System (LCRS) metric by expanding the Moon’s gravity field to spherical-harmonic degree 9 (including Love-number variations) and Earth’s tidal field to degree 8, truncating all terms below a fractional level of 5 10−18. We derive analytic mappings among TCB, TCG, TT, TCL and TL, yielding closed-form proper-to-coordinate time transformations and two-way time-transfer corrections with sub-picosecond (&lt; 0.2 ps) precision. We quantify secular rate constants and periodic perturbations—kinematic dilation, lunar monopole and multi- poles, Earth tides, and gravitomagnetic effects—for clocks on the lunar surface, in low lunar orbits, at the Earth–Moon L1 point, and in Near-Rectilinear Halo Orbits. Our analysis shows that lunar harmonics through ℓ = 9 and Earth tides through ℓ = 8 are required to achieve fractional stability of 5 10−18, providing the foundation for sub-ps clock synchronization, precision time/frequency transfer, and cm-level navigation throughout cislunar space. This formulation supports high-precison time/frequency transfer, relativistic geodesy, and precision navigation in Earth–Moon space, thereby enabling quantum communication links and fundamental physics experiments beyond low Earth orbit.

title: Discovery of Metallic Grain Boundary Resistance in the High Temperature Thermoelectric La3Te4

description: Added electrical resistance from grain boundaries is major limitation in the thermoelectric performance of many materials. This boundary resistance is typically observed as a large increase in resistivity at low temperature that decays exponentially at higher temperatures like the resistivity of an insulator or intrinsic semiconductor. As a result, engineering studies to mitigate boundary resistance have had most impact on low temperature thermoelectrics like Mg2Sb3 or improving the average zT of fine-grained, mid-temperature thermoelectrics like half-Heuslers. With much less influence at high temperature, there would be little expectation to improve the high temperature performance of thermoelectrics through mitigating electrical boundary resistance. In this work, however, we demonstrate that it is necessary to consider grain boundary resistance even in high temperature thermoelectrics by improving the thermoelectric performance at temperatures up to 1000 C in the thermoelectric La3Te4 by increasing grain size. In contrast with previous reports of grain boundary resistance in other thermoelectric materials, this improved performance is largest at high rather than low temperatures. This is a result of a new form of boundary resistance not previously reported in thermoelectric materials: uncharged or metallic boundary resistance. We observe a boundary resistance that increases linearly with temperature as expected in metals instead of the exponentially decaying resistance expected for charged boundaries. With both this new form of boundary resistance and the example of improved high temperature performance in La3Te4, we have shown that grain boundary engineering is still needed to optimize thermoelectric performance even for high temperature applications

title: Progress and outlook for constraining uncertainties in sea-level projections using observations

description: Coastal planning, mitigation, and adaptation efforts rely on credible sea-level projections generated by physical models. However, the large uncertainties in these projections pose a challenge for policymakers. Here we provide an overview of the main sources of uncertainty in model projections of sea-level change on multi-decadal to centennial timescales and we offer perspectives on the use of observations to narrow uncertainties. We propose several directions for future research, including improvements in emerging emulation techniques, more systematic quantification of uncertainty structure within both observations and models, lengthening observational records of processes, and expanding collaborations across physical and social sciences. Advancements in these areas are urgently needed, as the next phase of the Intergovernmental Panel on Climate Change assessment cycle gets underway.

title: Unprecedented Continental Drying, Shrinking Freshwater Availability, and Increasing Land Contributions to Sea Level Rise

description: Changes in terrestrial water storage (TWS) are a critical indicator of freshwater availability. We use NASA GRACE/GRACE-FO data to show that the continents have undergone unprecedented TWS loss since 2002. Areas experiencing drying increased by twice the size of California annually, creating ‘mega-drying’ regions across the northern hemisphere. While most of the world’s dry/wet areas continue to get drier/wetter, dry areas are now drying faster than wet areas are wetting. Changes in TWS are driven by high-latitude water losses, intense Central American/European droughts, and groundwater depletion, which accounts for 74% of TWS loss over non-glaciated continental regions. ‘Continental drying’ is having profound global impacts. 75% of the population lives in 106 countries that have been losing freshwater water since 2002. Furthermore, the continents now contribute more freshwater to sea level rise than the ice sheets, and drying regions now contribute more than land glaciers and ice caps. Urgent action is required to prepare for the major impacts of results presented.

title: Increased melt from Greenland’s most active glacier fuels enhanced coastal productivity

description: In Greenland’s coastal waters, seasonal phytoplankton blooms are critical for marine ecosystems, providing the basis for thefood web that supports Greenland’s inshore fisheries and a variety of large marine mammals. These blooms are also importantfor carbon fixation and contribute to the seasonal draw-down of carbon dioxide into the ocean. In Qeqertarsuup Tunua (DiskoBay), West Greenland, the typical Arctic spring bloom is followed by a secondary summertime bloom, elevating rates of annualprimary productivity. Recent evidence has linked the summertime bloom to melt from the Greenland Ice Sheet, which isdischarged into the ocean from beneath glaciers in the region, including Sermeq Kujalleq, the most active glacier on the icesheet. These discharge sites drive vigorous localized upwelling from the grounding line of marine-terminating outlet glaciersthat are hypothesized to alleviate nutrient limitation in the photic zone. However, this hypothesis remains largely untestedwith realistic numerical models capable of resolving variability in circulation resulting from glacier melt, inhibiting estimatesof primary productivity and atmospheric CO2 uptake. Here, we use a fjord-scale, high-resolution numerical model derivedfrom the data-assimilaltive ECCO-Darwin global-ocean biogeoechemistry model to quantify the extent to which upwelling inthe Qeqertarsuup Tunua glacier-ocean system modulates nutrient concentrations, summertime phytoplankton growth, andCO2 uptake on the continental shelf. We find that increased nutrient fluxes upwelled into the photic zone enhance net primaryproductivity by 15–40% in Qeqertarsuup Tunua during summer. However, despite this increased productivity, ocean CO2uptake only increases by approximately 3% relative to simulations without discharge when integrated annually, due to thecompeting influence of plume-driven reduction in solubility. As melt on the Greenland Ice Sheet is projected to increase inthe future, these results suggest that further climate-driven melt on large marine-terminating glaciers may drive substantialchanges in Greenland’s coastal ecosystems in coming decades.

title: Human contributions to evapotranspiration mitigate swings in dry to wet year transitions

description: California’s food and economic security depends on water availability, particularly under increasingly extreme climate scenarios. A key component of the water balance is evapotranspiration, the combination of soil and surface evaporation and plant transpiration. Evapotranspiration is influenced by natural drivers (e.g., climate, vegetation cover) and human intervention (e.g., irrigation, land management). Here, we analyze the transition between one of California’s driest years (2022) to an exceptionally wet year (2023) to assess evapotranspiration responses to climate extremes. Despite increased precipitation, total statewide evapotranspiration changed less than 10%. In 2022, human contributions accounted for 30% of statewide evapotranspiration and 80% in managed lands. In 2023, natural evapotranspiration increased, and human contributions fell by 30%, yet still comprised nearly 50% of evapotranspiration in managed areas. Our findings underscore the enduring role of human activity on California’s hydrology, even during wet years, and demonstrate a framework to separate natural and anthropogenic controls on evapotranspiration.

title: The Far-Infrared Enhanced Survey Spectrometer (FIRESS) for PRIMA: Science Drivers

description: We present the science drivers for the Far-Infrared Enhanced Survey Spectrometer (FIRESS), one of two science instrument on the PRobe Infrared Mission for Astrophysics (PRIMA). FIRESS is designed to meet science objectives in the areas of the origins of planetary atmospheres, the co-evolution of galaxies and supermassive black holes, and the buildup of heavy elements in the Universe. In addition to these drivers, FIRESS is envisioned as a versatile far-infrared spectrometer, capable of addressing science questions in most areas of astrophysics and planetary astronomy as part of a dominant General Observer (GO) program with 2/3 of the current science cases using FIRESS. We summarize how the instrument design choices and parameters enable the main science drivers as well as a broad and vibrant GO program.

title: PRIMA: PRIMAger, a far-infrared hyperspectral and polarimetric instrument

description: The PRobe far-Infrared Mission for Astrophysics (PRIMA) is a proposed infrared observatory for the next decade, with a 1.8\,m telescope actively cooled to 4.5\,K. On board, an infrared camera, PRIMAger, equipped with ultra-sensitive kinetic inductance detector (KID) arrays, will provide observers with coverage of mid-infrared to far-infrared wavelengths from 24 to 261\,$\mu$m. PRIMAger will offer two imaging modes: the Hyperspectral mode will cover the 24-84\,$\mu$m wavelength range with a spectral resolution R$\approx$10, while the Polarimetric mode will provide polarimetric imaging in 4 broad bands, from 80 to 261\,$\mu$m. These observational capabilities have been tailored to answer fundamental astrophysical questions such as black hole and star-formation co-evolution in galaxies, the evolution of small dust grains over a wide range of redshifts, and the effects of interstellar magnetic fields in various environments, as well as to open a vast discovery space with versatile photometric and polarimetric capabilities. PRIMAger is being developed by an international collaboration bringing together French institutes (Laboratoire d’Astrophysique de Marseille and CEA) through the Centre National d’Etudes Spatiales (CNES, France), the Netherlands Institute for Space Reseach (SRON, Netherlands), and the Cardiff University (UK) in Europe, as well as the Jet Propulsion Laboratory (JPL) and Goddard Space Flight Center (GSFC) in the USA.

title: Application and Comparison of Satellite-Derived Sea Surface Temperature Gradients to Identify Seasonal and Interannual Variability off the California Coast: Preliminary Results and Future Perspectives

description: The application of satellite-derived sea surface temperature in coastal regions is critical for resolving the dynamics of frontal features and coastal upwelling. Here, we examine and compare sea surface temperature (SST) gradients derived from two satellite products, the Multi-Scale Ultra-High Resolution SST Product (MUR, 0.01° grid scale) and the Opera-tional SST and Ice Analysis (OSTIA, 0.05° grid scale), available through the Group for High Resolution SST (GHRSST). Both products show similar seasonal variability, with maxima occurring in the summer time frame. Additionally, both products show an in-creasing trend of SST gradients near the coast. However, differences exist between the two products (maximum gradient intensities were around 0.11 and 0.06 °C/km for OSTIA and MUR, respectively). The potential contributions of both cloud cover and the collocation of the MUR SST onto the OSTIA SST grid product to these differences were examined. Spectra and coherences were examined at two specific latitudes along the coast where upwelling can occur. A major conclusion is that future work needs to focus on cloud cover and its impact on the derivation of SST in coastal regions. Future comparisons also need to apply collocation methodologies that maintain, as much as possible, the spatial variability of the high-resolution product.

title: Redox-Driven Mineral and Organic Associations in Jezero Crater, Mars

description: The Perseverance rover has explored and sampled igneous and sedimentary rocks within Jezero crater to characterize early Martian geological processes and habitability and search for potential biosignatures7. Upon entering Neretva Vallis, on Jezero crater’s western edge, Perseverance investigated distinctive mudstone and conglomerate outcrops of the Bright Angel formation. Here we report a detailed geological, petrographic, and geochemical survey of these rocks and show that organic carbon bearing mudstones in the Bright Angel formation contain sub-millimeter-scale nodules and mm-scale reaction fronts enriched in ferrous iron phosphate and sulfide minerals, likely vivianite and greigite, respectively. This organic carbon appears to have participated in post-depositional redox reactions that produced the observed Fe-phosphate and Fe-sulfide minerals. Geological context and petrography indicate that these reactions occurred at low temperatures. Within this context, we review the various pathways by which redox reactions that involve organic matter can produce the observed suite of Fe-, S-, and P-bearing minerals in laboratory and natural environments on Earth. Ultimately, we conclude that analysis of the core sample collected from this unit using high-sensitivity instrumentation on Earth will enable the measurements required to determine the origin of the minerals, organics, and textures it contains.
