Making kin: The archaeology and genetics of human relationships
Thanks to next generation sequencing (NGS), we can now access ancient biological relationships, including ancestry and parentage, with a startling level of clarity. This has led to recentering of kinship within archaeological discourse. In this paper, we argue that blood and biology are key elements of kin-making only in so far as they are contextualized and made sense of through social relations. We argue that the conceptions of kinship that underpin archaeogenetic studies are the product of a particular historical and political context. Archaeology, with its focus on the material remains of the past, provides opportunities to examine how other forms of material and technological intervention (including ritual, exchange, and the sharing of food) facilitated the creation of kinship links not solely rooted in the human body. Here, we consider the extent to which the social salience of biological relationships identified through ancient DNA analysis can be addressed without imposing contemporary forms of familial structure and gender ideology onto the past.Dank Next Generation Sequencing (NGS - Sequenzierung der nächsten Generation) haben wir jetzt erstaunlich klaren Zugang zu alten biologischen Beziehungen, einschließlich Abstammung und Elternschaft. Verwandtschaft ist dadurch wieder in den Mittelpunkt des archäologischen Diskurses gerückt. In diesem Aufsatz argumentieren wir, dass Blut und Biologie nur insofern Schlüsselelemente der Verwandtschaftsherstellung sind, als sie durch soziale Beziehungen kontextualisiert und mit Sinn gefüllt werden. Wir argumentieren, dass die Vorstellungen von Verwandtschaft, die archäogenetischen Studien zugrunde liegen, das Produkt eines bestimmten historischen und politischen Kontextes sind. Die Archäologie mit ihrem Fokus auf die materiellen Überreste der Vergangenheit bietet die Möglichkeit zu untersuchen, wie andere Formen der materiellen und technologischen Intervention (einschließlich Rituale, Austausch und das Teilen von Nahrung) die Herstellung von Verwandtschaftsbeziehungen ermöglicht haben, die nicht nur im menschlichen Körper verwurzelt waren. Wir betrachten hier, inwieweit die soziale Bedeutung biologischer Beziehungen, die durch Analysen alter DNA identifiziert wurden, adressiert werden kann, ohne der Vergangenheit heutige Formen der Familienstruktur und Geschlechterideologie aufzupressen

LSST Science Book, Version 2.0
A survey that can cover the sky in optical bands over wide fields to faint
magnitudes with a fast cadence will enable many of the exciting science
opportunities of the next decade. The Large Synoptic Survey Telescope (LSST)
will have an effective aperture of 6.7 meters and an imaging camera with field
of view of 9.6 deg^2, and will be devoted to a ten-year imaging survey over
20,000 deg^2 south of +15 deg. Each pointing will be imaged 2000 times with
fifteen second exposures in six broad bands from 0.35 to 1.1 microns, to a
total point-source depth of r~27.5. The LSST Science Book describes the basic
parameters of the LSST hardware, software, and observing plans. The book
discusses educational and outreach opportunities, then goes on to describe a
broad range of science that LSST will revolutionize: mapping the inner and
outer Solar System, stellar populations in the Milky Way and nearby galaxies,
the structure of the Milky Way disk and halo and other objects in the Local
Volume, transient and variable objects both at low and high redshift, and the
properties of normal and active galaxies at low and high redshift. It then
turns to far-field cosmological topics, exploring properties of supernovae to
z~1, strong and weak lensing, the large-scale distribution of galaxies and
baryon oscillations, and how these different probes may be combined to
constrain cosmological models and the physics of dark energy.Comment: 596 pages. Also available at full resolution at

Sloan Digital Sky Survey IV: Mapping the Milky Way, Nearby Galaxies, and the Distant Universe
We describe the Sloan Digital Sky Survey IV (SDSS-IV), a project encompassing three major spectroscopic programs. The Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2) is observing hundreds of thousands of Milky Way stars at high resolution and high signal-to-noise ratios in the near-infrared. The Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey is obtaining spatially resolved spectroscopy for thousands of nearby galaxies (median ). The extended Baryon Oscillation Spectroscopic Survey (eBOSS) is mapping the galaxy, quasar, and neutral gas distributions between and 3.5 to constrain cosmology using baryon acoustic oscillations, redshift space distortions, and the shape of the power spectrum. Within eBOSS, we are conducting two major subprograms: the SPectroscopic IDentification of eROSITA Sources (SPIDERS), investigating X-ray AGNs and galaxies in X-ray clusters, and the Time Domain Spectroscopic Survey (TDSS), obtaining spectra of variable sources. All programs use the 2.5 m Sloan Foundation Telescope at the Apache Point Observatory; observations there began in Summer 2014. APOGEE-2 also operates a second near-infrared spectrograph at the 2.5 m du Pont Telescope at Las Campanas Observatory, with observations beginning in early 2017. Observations at both facilities are scheduled to continue through 2020. In keeping with previous SDSS policy, SDSS-IV provides regularly scheduled public data releases; the first one, Data Release 13, was made available in 2016 July
The Fourteenth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the Extended Baryon Oscillation Spectroscopic Survey and from the Second Phase of the Apache Point Observatory Galactic Evolution Experiment
The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) has been in operation since 2014 July. This paper describes the second data release from this phase, and the 14th from SDSS overall (making this Data Release Fourteen or DR14). This release makes the data taken by SDSS-IV in its first two years of operation (2014–2016 July) public. Like all previous SDSS releases, DR14 is cumulative, including the most recent reductions and calibrations of all data taken by SDSS since the first phase began operations in 2000. New in DR14 is the first public release of data from the extended Baryon Oscillation Spectroscopic Survey; the first data from the second phase of the Apache Point Observatory (APO) Galactic Evolution Experiment (APOGEE-2), including stellar parameter estimates from an innovative data-driven machine-learning algorithm known as "The Cannon"; and almost twice as many data cubes from the Mapping Nearby Galaxies at APO (MaNGA) survey as were in the previous release (N = 2812 in total). This paper describes the location and format of the publicly available data from the SDSS-IV surveys. We provide references to the important technical papers describing how these data have been taken (both targeting and observation details) and processed for scientific use. The SDSS web site (www.sdss.org) has been updated for this release and provides links to data downloads, as well as tutorials and examples of data use. SDSS-IV is planning to continue to collect astronomical data until 2020 and will be followed by SDSS-V
WAC@30 – Give the past a future. Some comments from Europe
The following is the text of a short speech given by the first author at WAC-8 in Kyoto, Japan on Mon 29 August, 2016. Prof. Koji Mizoguchi invited representatives from various international archaeological associations to address the World Archaeology Congress on the future of archaeology as part of a celebration of the World Archaeology Congress' 30th anniversary.N
