Open Access Mitochondrial genomes reveal an east to west cline of steppe ancestry in Corded Ware populations, by Juras et al., Scientific Reports (2018) 8:11603.
Interesting excerpts (emphasis mine, references have been deleted for clarity):
Ancient DNA was extracted from the Corded Ware culture individuals excavated in southeastern Poland (N = 12) and Moravia (N = 3). Late Eneolithic (N = 5) and Bronze Age human remains (N = 25) originated from western Ukraine and came from the Yampil barrow cemetery complex located in the north–western region of the Black Sea. Bronze Age individuals were associated with different archaeological

New paper (behind paywall) Paternal origin of Paleo-Indians in Siberia: insights from Y-chromosome sequences by Wei et al., Eur. J. Hum. Genet. (2018)
Interesting excerpts (for Eurasian migrations):
Differentiation and diffusion in Palaeolithic Siberia
Based on the phylogenetic analyses and the current distributions of relative sub-lineages, we propose that the prehistoric population differentiation in Siberia after the LGM (post-LGM) provided the genetic basis for the emergence of the Paleo-Indian, American aborigine, population. According to the phylogenetic tree of Y-chromosome haplogroup C2-M217 (Fig. 2 and Figure S1), eight sub-lineages emerged in a short period between 15.3 kya and 14.3 kya

Looking for information on Novosvobodnaya samples from Wang et al. (2018) for my latest post, I stumbled upon this from the Supplementary Data 2 (download the Excel table):
Skeletal element: petrous
Date: 4251-3976 calBCE
SNPs hit on autosomes: 167445
The data on Mathieson et al. (2018) is as follows:
Skeletal element: petrous

This is the first of a series of posts analyzing the findings of the recent Nature papers Olalde et al.(2018) and Mathieson et al.(2018) (abbreviated O&M 2018).
As expected, the first Y-DNA haplogroup of a sample from the North Pontic region (apart from an indigenous European I2 subclade) during its domination by the Yamna culture is of haplogroup R1b-L23, and it is dated ca. 2890-2696 BC. More specifically, it is of Z2103 subclade, the main lineage found to date in Yamna samples. The site in question is Dereivka, “in the southern part of the middle … Read the rest “Consequences of O&M 2018 (I): The latest West Yamna “outlier””
I have written before about how the Late Neolithic sample from Zvejnieki seemed to be an outlier among Corded Ware samples (read also the Admixture analysis section on the IEDDM), due to its position in PCA, even more than its admixture components or statistical comparison might show.
In the recent update to Northern European samples in Mittnik et al. (2018), an evaluation of events similar to the previous preprint (2017) is given:
Computing D-statistics for each individual of the form D(Baltic LN, Yamnaya; X, Mbuti), we find that the two individuals from the early phase of the

The latest publication of Documenta Praehistorica, vol. 44 (2017) is a delight for anyone interested in Indo-European and Uralic studies, whether from a linguistic, archaeological, anthropological, or genetic point of view. Articles are freely downloadable from the website.
The following is a selection of articles I deem more interesting, but almost all are.
