ABoVE: Active Layer Soil Characteristics at Selected Sites Across Alaska

This dataset provides soil active layer characteristics from nine locations across Alaska. Soil samples were collected in 2016 except for one site which was sampled in 2018. Soil cores were collected from each site using a steel barrel and plastic sample tube attached to a hand drill. At the majority of sites, samples were taken from each end of three 30-m transects (i.e. samples collected at the 0 m and 30 m location of each transect). The entire thawed horizon (active layer) was sampled where possible, and the length of cores varies among sites. Cores were kept frozen until analysis in the lab. Samples were sectioned by horizon (organic and mineral), and the organic horizon was split into subsections so that no section was longer than approximately 10 cm. Coarse roots were removed, dried and weighed. Soils were measured for gravimetric water content, percent soil organic matter (SOM), pH, and bulk density. Locations were selected to investigate fire disturbance, to span the range of permafrost regions from continuous to sporadic, and to cover vegetation types from boreal forests, tussock tundra, upland willow/herbaceous scrub, and lowland fen and wet tundra sites across Alaska. The data are provided in comma-separated values (CSV) format.

Sigma Orionis Cluster XMM-Newton X-Ray Point Source Catalog

This table contains some of the results of an analysis of the full EPIC field in an XMM-Newton observation of the young (~2 - 4 Myr) cluster around the hot star sigma Orionis. The authors have detected 175 X-ray sources, 88 of which have been identified with cluster members, including very low-mass stars down to the substellar limit. They detected eleven new possible candidate members from the 2MASS (&lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/II/246"&gt;CDS Cat. &lt;II/246&gt;&lt;/a&gt;) catalog. The authors find that late-type stars have a median log L&lt;sub&gt;X&lt;/sub&gt;/L&lt;sub&gt;bol&lt;/sub&gt; ~ -3.3, i.e. very close to the saturation limit. They detected significant variability in ~ 40% of late-type members or candidates, including 10 flaring sources; rotational modulation was detected in one K-type star and possibly in another 3 or 4 stars. Spectral analysis of the brightest sources shows typical quiescent temperatures in the range T&lt;sub&gt;1&lt;/sub&gt; ~ 0.3 - 0.8 keV and T&lt;sub&gt;2&lt;/sub&gt; ~ 1 - 3 keV, with subsolar abundances Z ~ 0.1 - 0.3 solar, similar to what is found in other star-forming regions and associations. The authors find no significant difference in the spectral properties of classical and weak-lined T Tauri stars, although classical T Tauri stars tend to be less X-ray luminous than weak-lined T Tauri stars. XMM-Newton observations of the sigma Ori cluster, centered on the hot star sigma Ori AB, were carried out as part of the Guaranteed Time of Roberto Pallavicini using both the EPIC MOS and PN cameras and the RGS instrument. The observation (ID 0101440301) started at 21:47 UT on March 23, 2002 and ended at 9:58 UT on March 24, 2002, for a total duration of 43 ks. The EPIC cameras were operated in Full Frame mode using the thick filter. This table contains the combined list of 88 X-ray sources positionally (&lt;= 5&quot;) associated with confirmed or candidate cluster members, and 66 X-ray sources with no such positional associations, detected above a significance threshold of 5 sigma. The two X-ray sources (source numbers 67 and 167) with 2 possible positional associations are listed twice, once for each positional association, with the X-ray information repeated. Thus, there are 156 entries in this HEASARC table. This table was created by the HEASARC in May 2007 based on &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/446/501"&gt;CDS catalog J/A+A/446/501&lt;/a&gt; files tablea1.dat and tableb.dat.

INTEGRAL IBIS AGN Catalog Update

In the most recent IBIS survey based on observations performed during the first 1000 orbits of INTEGRAL, there are listed 363 high-energy emitters firmly associated with AGN, 107 of which are reported here for the first time. The authors have used X-ray data to image the IBIS 90% error circle of all the AGN in the sample of 107, in order to obtain the correct X-ray counterparts, locate them with arcsecond accuracy and therefore pinpoint the correct optical counterparts. This procedure has led to the optical and spectral characterization of the entire sample. This new set consists of 34 broad line or type 1 AGN, 47 narrow line or type 2 AGN, 18 blazars and 8 sources of unknown class. These eight sources have been associated with AGN from their positional coincidence with 2MASX/Radio/X-ray sources. Seven high-energy emitters have also been included since they are considered to be good AGN candidates. Spectral analysis has been already performed on 55 objects and the results from the most recent and/or best statistical measurements have been collected. For the remaining 52 sources, the authors report the spectral analysis for the first time in this work. They have been able to obtain full X-ray coverage of the sample making use of data from Swift/XRT, XMM-Newton and NuSTAR. In addition to the spectral characterization of the entire sample, this analysis has enabled the authors to identify peculiar sources and by comparing different data sets, highlight flux variability in the 2-10 keV and 20-40 keV bands. In the reference paper, the authors present the X-ray and optical follow-up work on 107 new AGN recently detected by INTEGRAL. Fortunately, they have been able to obtain full X-ray coverage of the entire sample making use of data from the Swift/XRT, Newton-XMM, and NuSTAR archives or through Swift/XRT follow-up observations that they triggered. The HEASARC notes that this table of AGN newly detected by INTEGRAL and not included in the original INTEGRAL IBIS AGN Catalog (Malizia et al. 2012, MNRAS, 426, 1750, available at the HEASARC as the INTIBISAGN table) actually contains 108 AGN plus 8 candidate AGN, for a total of 116 objects, rather than the 107 plus 7 candidate AGN totalling 114 objects that are quoted in the abstract of the reference paper (and stated above). The reason for this discrepancy is not known to the HEASARC. This table was created by the HEASARC in November 2017 based on &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/MNRAS/460/19"&gt;CDS Catalog J/MNRAS/460/19&lt;/a&gt; files tablea1.dat and refs.dat.

GALEX/SDSS z=0.5-1.5 QSO Candidates Catalog

A sample of ~60,000 objects from the combined Sloan Digital Sky Survey-Galaxy Evolution Explorer (SDSS-GALEX) database with UV-optical colors that should isolate QSOs in the redshift range 0.5 to 1.5 is discussed. The authors use SDSS spectra of a subsample of ~ 4,500 to remove stellar and galaxy contaminants in the sample to a very high level, based on the 7-band photometry. In their paper, they discuss the distributions of redshift, luminosity, and reddening of the 19,100 QSOs (~96%) that they estimate to be present in their final sample of 19,812 point sources. This latter catalog is available in the present table. This paper is based on archival data from the Galaxy Evolution Explorer (GALEX) which is operated for NASA by the California Institute of Technology under NASA contract NAS5-98034, and on data from the SDSS. This table was created by the HEASARC in March 2011 based on the electronic version of Table 2 from the reference paper which was obtained from the AJ web site. Some of the values for the name parameter in the HEASARC&#39;s implementation of this table were corrected in April 2018. This is a service provided by NASA HEASARC .

NASA Aircraft Bioaerosol Collector (ABC) -2

Several studies have reported that microorganisms are co-transported with globally dispersed aerosols and that microbial DNA and viable cells have been detected at both low and high altitudes. In an effort to investigate how microbial patterns change with altitude, two research flights were flown using NASA's C-20A Gulfstream III aircraft over the Sierra mountains in the Southern California/Nevada region over two consecutive days. During each flight, the aircraft reached 40,000 ft and lowered to 30,000 ft, 20,000 ft, and 10,000 ft in a stair-step pattern. Bioaerosol samples were collected at each altitude for 30 minutes on gelatinous filters using the Aircraft Bioaerosol Collector (ABC). DNA was extracted from the bioaerosol sample. Whole genome sequencing was performed on the extracted DNA using an Illumina NextSeq 500.

Comparative Genomic Analysis of Klebsiella Exposed to Various Space Conditions at the International Space Station

Due to the bacteria's evolved resistance to radiation, Klebsiella poses a great threat to not only planetary protection, but also to the integrity of future biological experiments in outer space. While previous literature has shown varying degrees of sensitivity in klebsiella to a high radiation environment, not much is known about the genetic component that yields this microbial advantage. Our research objective is to pinpoint the genetic advantage some Klebsiella species acquire as they are exposed to a space-like environment through a comparison of whole genomes sequences to better control microbial contamination onboard the ISS.

ASCA Large Sky Survey

The ASCA Large Sky Survey (LSS) was the first wide-area unbiased survey with the ASCA satellite in the 0.7 - 10 keV band around the North Galactic Pole region covering a continuous area of 7 square degrees. To make the best use of ASCA&#39;s capabilities, the authors developed a new source detection method in which the complicated detector responses were fully taken into account. Applying this method to the entire LSS data independently in the total (0.7 - 7 keV), hard (2 - 10 keV), and soft (0.7 - 2 keV) bands, they detected 107 sources altogether, with sensitivity limits of 6 x 10&lt;sup&gt;-14&lt;/sup&gt; (0.7 - 7 keV), 1 x 10&lt;sup&gt;-13&lt;/sup&gt; (2 - 10 keV), and 2 x 10&lt;sup&gt;-14&lt;/sup&gt; ergs/s/cm&lt;sup&gt;2&lt;/sup&gt; (0.7 - 2 keV), respectively. The complete list of detected sources is presented in this table. The detection criteria that needed to be satisfied were: (i) the significance of the summed count rate of the GIS and the SIS should exceed 4.5, and (ii) the significance of either the GIS or the SIS should also exceed 3.5. This database was created by the HEASARC in December 2001 based on the ADC/&lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/ApJ/518/656"&gt;CDS Catalog J/ApJ/518/656&lt;/a&gt;.

Fermi LAT Monitored Source List

The Fermi LAT table of monitored sources provides daily and weekly fluxes for sources of interest as described in &lt;a href="http://fermi.gsfc.nasa.gov/ssc/data/policy/LAT_Monitored_Sources.html"&gt;http://fermi.gsfc.nasa.gov/ssc/data/policy/LAT_Monitored_Sources.html&lt;/a&gt;. In addition, similar information will be released for any source which flares above 2x10&lt;sup&gt;-6&lt;/sup&gt; photons cm&lt;sup&gt;-2&lt;/sup&gt; s&lt;sup&gt;-1&lt;/sup&gt; until the flux drops below 2x10&lt;sup&gt;-7&lt;/sup&gt; photons cm&lt;sup&gt;-2&lt;/sup&gt; s&lt;sup&gt;-1&lt;/sup&gt;. Fermi is currently in survey mode and observes the entire sky every day. However, if a source does not exceed the detection threshold, no entry will appear in this catalog. The tabulated fluxes are derived at the LAT Instrument Science Operations center in a &#39;quick look&#39; analysis to produce results quickly to facilitate follow-up multi-wavelength observations of flaring sources. The table of released fluxes will be updated as analysis and calibrations improve. &lt;b&gt;These early flux estimates do not include systematic uncertainties and do not&lt;/b&gt; &lt;b&gt;have an absolute flux calibration&lt;/b&gt;. Use of these data as absolute flux measurements for constraining models or for comparison to other data is strongly discouraged at this time. In addition to overall normalization uncertainties, source fluxes may have variations of up to 10% due to currently-uncorrected dependencies of the gamma-ray detection efficiency on variations of the particle background in orbit. Please note that these results are produced using preliminary instrument response functions and calibrations. The quality and stability of these results will improve when updated calibrations become available over the coming months. This database table is created by the HEASARC from FITS tables received from the Fermi Science Support Center (FSSC). The ASP FITS files are produced by the LAT Instrument Science Operations Center (LISOC) and transferred from the LISOC to the FSSC about once per week. This is a service provided by NASA HEASARC .

C2D Candidate YSO OFF-CLOUD Catalog

The Cores to Disks (C2D) Spitzer Legacy Program used all three Spitzer instruments (IRAC, MIPS, and IRS) to observe sources that span the evolutionary sequence from molecular cores to protoplanetary disks, encompassing a wide range of cloud masses, stellar masses, and star-forming environments. In addition to targeting about 150 known compact cores, it surveyed with IRAC and MIPS (3.6-70 mum) the entire areas of five of the nearest large molecular clouds for new candidate protostars and substellar objects as faint as 0.001 solar luminosities. C2D observed with IRAC and MIPS about 190 systems likely to be in the early stages of planetary system formation (ages up to about 10 Myr), probing the evolution of the circumstellar dust, the raw material for planetary cores.\n\nThe Candidate YSO OFF-CLOUD Catalog lists the candidate young stellar objects (YSOs) in the C2D OFF-CLOUD fields (ChamaeleonII (CHA_II), Lupus (LUP), Ophiuchus (OPH), Perseus (PER) and Serpens (SER)). It is derived from the Full Catalog using methodology described in Harvey et al. (2007b).

Targeting myostatin/activin A protects against skeletal muscle and bone loss during spaceflight [plasma proteomics]

Among the physiological consequences of extended spaceflight are loss of skeletal muscle and bone mass. One signaling pathway that plays an important role in maintaining muscle and bone homeostasis is that regulated by the secreted signaling proteins, myostatin (MSTN) and activin A. Here, we used both genetic and pharmacological approaches to investigate the effect of targeting MSTN/activin A signaling in mice that were sent to the International Space Station. Wild type mice lost significant muscle and bone mass during the 33 d spent in microgravity. Muscle weights of Mstn -/- mice, which are about twice those of wild type mice, were largely maintained during spaceflight. Systemic inhibition of MSTN/activin A signaling using a soluble form of the activin type IIB receptor (ACVR2B), which can bind each of these ligands, led to dramatic increases in both muscle and bone mass, with effects being comparable in ground and flight mice. Exposure to microgravity and treatment with the soluble receptor each led to alterations in numerous signaling pathways, which were reflected in changes in levels of key signaling components in the blood as well as their RNA expression levels in muscle and bone. These findings have implications for therapeutic strategies to combat the concomitant muscle and bone loss occurring in people afflicted with disuse atrophy on Earth as well as in astronauts in space, especially during prolonged missions.
