Substrate Matters: Ionic Silver Alters Lettuce Growth, Nutrient Uptake, and Root Microbiome in a Hydroponics System

Ionic silver (Ag+) is being investigated as a residual biocide for use in NASA spacecraft potable water systems on future crewed missions. This water will be used to irrigate future spaceflight crop production systems. We have evaluated the impact of three concentrations (31 ppb, 125 ppb, and 500 ppb) of ionic silver biocide solutions on lettuce in an arcillite (calcinated clay particle substrate) and hydroponic (substrate-less) growth setup after 28 days. Lettuce plant growth was reduced in the hydroponic samples treated with 31 ppb silver and severely stunted for samples treated at 125 ppb and 500 ppb silver. No growth defects were observed in arcillite-grown lettuce. Silver was detectable in the hydroponic-grown lettuce leaves at each concentration but was not detected in the arcillite-grown lettuce leaves. Specifically, when 125 ppb silver water was applied to a hydroponics tray, Ag+ was detected at an average amount of 7 ug/g (dry weight) in lettuce leaves. The increase in Ag+ corresponded with a decrease in several essential elements in the lettuce tissue (Ca, K, P, S). In the arcillite growth setup, silver did not impact the plant root zone microbiome in terms of alpha diversity and relative abundance between treatments and control. However, with increasing silver concentration, the alpha diversity increased in lettuce root samples and in the water from the hydroponics tray samples. The genera in the hydroponic root and water samples were similar across the silver concentrations but displayed different relative abundances. This suggests that ionic silver was acting as a selective pressure for the microbes that colonize the hydroponic water. The surviving microbes likely utilized exudates from the stunted plant roots as a carbon source. Analysis of the root-associated microbiomes in response to silver showed enrichment of metagenomic pathways associated with alternate carbon source utilization, fatty-acid synthesis, and the ppGpp (guanosine 3'-diphosphate 5'-diphosphate) stringent response global regulatory system that operates under conditions of environmental stress. Nutrient solutions containing Ag+ in concentrations greater than 31 ppb in hydroponic systems lacking cation-exchange capacity can severely impact crop production due to stunting of plant growth.

Spectroscopic Binary Orbits Ninth Catalog (Dynamic Version)

The Ninth Catalog of Spectroscopic Binary Orbits (SB9) continues the series of compilations of spectroscopic orbits carried out over the past 35 years by Batten and collaborators, e.g., the 8th SBO Catalog (SB8, &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/V/64"&gt;CDS Catalog V/64&lt;/a&gt;) of Batten, Fletcher and MacCarthy 1989, Publ. DAO, 17, 1. This catalog is regularly updated. This version of SB9 contains orbits for over three thousand binary systems; notice that the numbers of orbits and binary systems included in this version differ from those in the reference publication, as the latter reflected the 2004 May 1 status of the catalog, when it had 2694 orbits for 2386 binary systems. There is an online version of this catalog, maintained by the authors, which is continuously updated, at &lt;a href="http://sb9.astro.ulb.ac.be/"&gt;http://sb9.astro.ulb.ac.be/&lt;/a&gt;. This table was created by the HEASARC based on the &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/B/sb9"&gt;CDS Catalog B/sb9&lt;/a&gt;, using the files main.dat, alias.dat, orbits.dat and notes.txt. The CDS updates it regularly, and this HEASARC version is accordingly updated within a week of such updates. This is a service provided by NASA HEASARC .

Spitzer Extragalactic Representative Volume Survey XMM-LSS 2-band Catalog

The "Spitzer Extragalactic Representative Volume Survey" (SERVS) Exploration Science program conducted deep IRAC 3.6 and 4.5 micron observations of five extragalactic fields (ELAIS-N1, Lockman Hole, XMM, ELAIS-S1, and CDFS).\n\nObjects in the single band catalogs are not required to have any counterparts in the other band. They are cut at CSNR > 5 and also have the low coverage areas at the edges of the survey omitted (POLY=1), resulting in a single-band reliability flag REL=1. They are thus deeper than the 2-band high reliability catalogs. These should be used if you are matching with a reliable catalog from another band (e.g. near-infrared), and simply want as many matches as possible, or are doing a statistical study.

Metagenome profiling of feces from mice flown on the RRRM-1 mission

In Rodent Research Reference Mission-1 (RRRM-1), forty female BALB/cAnNTac mice were flown on the International Space Station. To assess differences in outcomes due to age, twenty 10-12 week-old and twenty 32 week-old mice were flown, respectively. To directly assess spaceflight effects, half of the young and old mice (10 old, 10 young) were sacrificed on-orbit after 22-23 days (ISS Terminal, ISS-T), while the other half (10 old, 10 young) were returned live to Earth after 40 days and allowed to recover for 2 days (Live Animal Return, LAR) before sacrifice. Both the ISS-T and LAR animals had independent ground controls (10 mice housed in flight hardware in matched environmental conditions), basal controls (10 mice sacrificed 1 day after launch), and vivarium controls (10 mice housed within standard vivarium habitats). Thus RRRM-1 included a total of 160 mice. Feces were removed from 145 animals and preserved by flash freezing in liquid nitrogen and stored at -80 ˚C until DNA was extracted, and libraries generated and sequenced (target 10 M clusters per sample, PE 251 bp). This dataset features whole-genome shotgun metagenomics sequencing data from 8-10 feces samples per group.

eROSITA All-Sky Survey (First 6 Months) Three-Band (2.3-5.0 keV) Source Catalog

The eROSITA telescope array aboard the Spektrum Roentgen Gamma (SRG) satellite began surveying the sky in December 2019, with the aim of producing all-sky X-ray source lists and sky maps of an unprecedented depth. The authors present catalogs of both point-like and extended sources using the data acquired in the first six months of survey operations (eRASS1; completed June 2020) over the half sky whose proprietary data rights lie with the German eROSITA Consortium. This catalog contains all X-ray sources detected in the 2.3-5 keV band with detection likelihood &gt; 12. The 5466 sources detected in the less sensitive but harder 2.3-5 keV band is the result of the first true imaging survey of the entire sky above 2 keV. The eRASS1 main catalog, &lt;a href="/W3Browse/erosita/erass1main.html"&gt;eRASS1MAIN&lt;/a&gt;, contains nearly 930000 entries detected in the most sensitive 0.2-2.3 keV energy range and the sources (only the strongly associated ones) from the main catalog have been linked to eRASS1MAIN in this catalog. The reference paper presents methods to identify and flag potential spurious sources in the catalogs, which were applied for this work, and the authors tested and validated the astrometric accuracy via cross-comparison with other X-ray and multi-wavelength catalogs. The catalogs form part of the first data release (DR1) of the SRG/eROSITA all-sky survey. Beyond the X-ray catalogs, DR1 contains all detected and calibrated event files, source products (light curves and spectra), and all-sky maps. The data files are linked to the table and also accessible from the &lt;a href="/docs/srg/erosita/"&gt;HEASARC eROSITA&lt;/a&gt; and &lt;a href="https://erosita.mpe.mpg.de/dr1/"&gt;eROSITA-DE ERASS1&lt;/a&gt; websites. The catalog uses the following designation for indicating the bands for the different measurement: &lt;pre&gt; Band Energy range (keV) 0 0.2 - 5.0 1 0.2 - 0.6 2 0.6 - 2.3 3 2.3 - 5.0 &lt;/pre&gt; This database table was ingested by the HEASARC in June 2024 and is based upon the &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/682/A34"&gt;CDS Catalog J/A+A/682/A34&lt;/a&gt; file erass1-h.dat. In some cases, the HEASARC has altered the original field names, as per HEASARC conventions, and provides the original field names in square brackets. This is a service provided by NASA HEASARC .

Response of Staphylococcus aureus physiology and Agr quorum sensing to low shear modelled microgravity

Staphylococcus aureus is commonly isolated from astronauts returning from spaceflight missions. Previous analysis of BRIC-23 omics data generated from S. aureus low Earth orbit cultures indicated significantly increased expression of the Agr quorum sensing system and its downstream targets in spaceflight samples compared to ground controls. In this current study, the rotary cell culture system (RCCS) was used to investigate the effect of low shear modelled microgravity (LSMMG) on S. aureus physiology and Agr activity. When cultured in BRIC-23 medium and temperature conditions, S. aureus LSMMG cultures exhibited decreased agr expression and altered growth compared to normal gravity control cultures, which are typically oriented with gas permeable membrane on bottom of the high aspect rotating vessel (HARV). However, when grown in an inverted gravity control orientation (membrane on top of the HARV), reduced Agr activity was observed relative to both traditional control and LSMMG cultures, signifying that oxygen availability may affect the observed differences in agr expression. Metabolite assays revealed increased lactate and decreased acetate excretion in both LSMMG and inverted control cultures. Secretomics analysis of LSMMG, control, and inverted control HARV culture supernatants corroborated these results, with inverted and LSMMG cultures exhibiting decreased abundance of Agr-regulated virulence factors and increased abundance of low-oxygen metabolic proteins. Collectively, these studies suggest that orientation of the HARV gas permeable membrane can affect S. aureus physiology and Agr quorum sensing in the RCCS, a variable that should be considered when interpreting data using this ground-based microgravity model.

The impact of deep space radiation on cognitive performance: From biological sex to biomarkers to countermeasures (Elevated Plus Maze, Novel Object Recognition, Open Field, Radial Arm Water Maze, and Three Chamber Social Isolation/Interaction)

In the coming decade, astronauts will travel back to the moon in preparation for future Mars missions. Exposure to galactic cosmic radiation (GCR) is a major obstacle for deep space travel. Using multivariate principal components analysis, we found sex dimorphic responses in mice exposed to accelerated charged particles to simulate GCR (GCRsim); males displayed impaired spatial learning, whereas females did not. Mechanistically, these GCRsim induced learning impairments corresponded with chronic microglia activation and synaptic alterations in the hippocampus. Temporary microglia depletion shortly after GCRsim exposure mitigated GCRsim induced deficits measured months after the radiation exposure. Furthermore, blood monocyte levels measured early after GCRsim exposure were predictive of the late learning deficits and microglia activation measured in the male mice. Our findings (i) advance our understanding of charged particle induced cognitive challenges, (ii) provide evidence for early peripheral biomarkers for identifying late cognitive deficits, and (iii) offer potential therapeutic strategies for mitigating GCR induced cognitive loss. This study derives results from the behavior assays Elevated Plus Maze, Novel Object Recognition, Open Field, Radial Arm Water Maze, and Three Chamber Social Isolation/Interaction. These data are related to the Flow Cytometry data in OSD-776 (blood), OSD-777 (Microglia), and OSD-778 (Synapse).

Effects of 32 Days Aboard the ISS on Gastrocnemius Tendon Nanomechanics (Gastrocnemius tendon, RR-1 and Atomic Force Microscopy)

Collagen is an essential component of connective tissue and plays a crucial role in elasticity, stability, and force distribution. While the adaptations of tendon to internal stimuli have been extensively researched, the impact of environmental factors (such as microgravity) on its structure and function at the nanoscopic scale (i.e., fibril level) remains largely unexplored. The purpose of this study was to determine the effects of 32 days (d) aboard the International Space Station (ISS) on murine tendon collagen fibril morphology and nanomechanics (Young’s Modulus, YM). Gastronemius tendon samples from 16wk old female C57BL/6J mice aboard NASA Rodent Research-1 underwent chemical processing and mechanical isolation. Subsequently, collagen fibrils (n equals 17) were studied via atomic force microscopy (AFM, JPK NanoWizard 4a) to compare the morphology (diameter, height) and nanomechanics (average YM) between spaceflight (SF) and ground control (GC) mouse tendon samples. The qp-BioAC-CB1 cantilever (spring constant: 0.3 N/m, tip radius: 10µm) was used under quantitative imaging mode (Qi) for all force and morphological measurements. The data from 17 micrographs (SF n equals 5; GC n equals 12) was processed via the JPK Data Processing Software (Version 6.4.5.), and finally analyzed via Gwyddion (Version 2.62). To our knowledge, this is the first investigation to use AFM QI-mode on tendon collagen fibrils after spaceflight. Mean fibril size and YM were similar between Space Flight (SF) and Ground Control (GC) mouse tendon fibrils after 32 days of space flight; these results suggest that collagen fibrils may require more time to adapt to changes in their environment, and/or more rapid changes may take place at different levels of the collagen hierarchy. This data provides valuable insights into mammalian tissue adaptations during spaceflight, and future research should continue these investigations with longer-duration missions to build a time-course of tendon adaptations to microgravity. This dataset includes results from atomic force microscopy using gastronemius tendon tissue.

ROSAT PSPC Galactic Center Soft X-Ray Source Catalog

This table contains a catalog of 107 point-like X-ray sources derived from a systematic analysis of all the ROSAT PSPC observations of the Galactic Center region performed in 1992-1993. Besides Sgr A*, the massive black hole at the galactic center, 41 X-ray sources have been positionally associated with already classified objects. Twenty are identified with foreground stars and five with known Low Mass X-ray Binaries (LMXBs). The majority of the sources in this catalog still remains unidentified. They are hard and/or severely absorbed and probably represent a large population of X-ray binaries located in the galactic center region, accreting at low accretion rates, and still largely unknown. Analyses were performed in 4 different energy ranges: 0.1 - 2.4 keV (PSPC channels 8 - 240, the total energy band T), 0.1 - 0.4 keV (PSPC channels 8 - 40, the soft energy band S), 0.5 - 0.9 keV (PSPC channels 52 - 90, the medium energy band), and 0.9 - 2.4 keV (PSPC channels 91 - 240, the hard energy band H). A maximum likelihood method was applied to the merged photon lists in each band. Only a detection liklihood larger than 10 (corresponding to a probability of a chance detection smaller than e&lt;sup&gt;-10&lt;/sup&gt;) was considered to be a true source. This table was created by the HEASARC in March 2012 based on &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/368/835"&gt;CDS Catalog J/A+A/368/835&lt;/a&gt; file table3.dat.

Transcriptional profiling of soleus muscle from mice flown on the RR-23 mission

The objective of the Rodent Research-23 mission (RR-23) was to better understand the effects of spaceflight on the eyes, specifically on the structure and function of the arteries, veins, and lymphatic vessels that are needed to maintain vision. To this end, twenty male, C57BL/6J, 16-17 weeks-old mice were delivered to the International Space Station (ISS) on SpaceX-21 in a single transporter, transferred to two rodent habitats, and maintained in microgravity for 38 days. Flight mice were then returned to Earth alive (January 13th, 2021). After splashdown in the Atlantic Ocean, mice were transported to Kennedy Space Center via helicopter. The 20 Flight (FLT), 20 Habitat Ground Control (GC), and 20 Vivarium Ground Control (VIV) mice were removed from Rodent Transporters (FLT and GC) or vivarium cages (VIV), placed into shipping containers, and flown to Texas A and M University. There, mice underwent post-flight procedures, before euthanasia and tissue collection. FLT, GC and VIV animals were euthanized and dissected on Jan 14th, 17th or 20th of 2021, respectively. Soleus muscle samples were preserved by immersion in liquid nitrogen and stored at -80C until RNA was extracted, and libraries generated and sequenced (target 60 M clusters per sample, PE 149 bp). This dataset features 9 samples from the Flight group, 9 samples from the Habitat Ground Control group, and 9 samples from the Vivarium Ground Control group.

ROSAT/XMM-Newton 13-hr Deep Field VLA 20-cm Source Catalog

In order to determine the relationship between the faint X-ray and faint radio source populations, and hence to help understand the X-ray and radio emission mechanisms in those faint source populations, the authors have made a deep 1.4-GHz Very Large Array radio survey of the 13&lt;sup&gt;h&lt;/sup&gt; 34&lt;sup&gt;m&lt;/sup&gt; 37&lt;sup&gt;s&lt;/sup&gt;, +37&lt;sup&gt;o&lt;/sup&gt; 54&#39; 44&quot; (J2000) ROSAT/XMM-Newton X-ray Survey Area (McHardy et al. 1998, MNRAS, 295, 641; Loaring et al. 2005, MNRAS, 362, 1371: the catalog of XMM-Newton sources from the latter paper is available at the HEASARC as the ROS13HRXMM table). From a combined VLA data set of 10 hours of B-configuration data and 14 hours of A-configuration data, maps with 3.35-arcsec resolution and a noise limit of 7.5 microJansky (&micro;Jy) were constructed. A complete sample of 449 sources was detected within a 30-arcmin diameter region above a 4-sigma detection limit of 30 uJy, at the map center, making this one of the deepest radio surveys at this frequency. The differential source count shows a significant upturn at sub-milliJansky flux densities, similar to that seen in other deep surveys at 1.4 GHz (e.g. the Phoenix survey, Hopkins et al. 2003, AJ, 125, 465: available at the HEASARC as the PDS1P4GHZ table), but larger than that seen in the Hubble Deep Field (HDF) which may have been selected to be underdense. This upturn is well modeled by the emergence of a population of medium-redshift star-forming galaxies which dominate at faint flux densities. The brighter source counts are well modeled by active galactic nuclei. This HEASARC table contains the catalog of 449 radio sources in a region of 30-arcmin diameter centered on the ROSAT/XMM 13-hours field which were detected at 1.4 GHz (20 cm) above a detection threshold of 4 sigma, equivalent to 30 uJy at the phase center. This table was created by the HEASARC in July 2013 based on &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/MNRAS/352/131"&gt;CDS Catalog J/MNRAS/352/131&lt;/a&gt; file table a1.dat.
