New paper (behind paywall) The female ancestor’s tale: Long‐term matrilineal continuity in a nonisolated region of Tuscany, by Leonardi et al. Am J Phys Anthr (2018).
EDIT (10 SEP 2018): The main author has shared an open access link to read the PDF.
Here we analyze North-western Tuscany, a region that was a corridor of exchanges between Central Italy and the Western Mediterranean coast.
We newly obtained mitochondrial HVRI sequences from 28 individuals, and after gathering published data, we collected genetic information for 119 individuals from the region. Those span five periods during the last 5,000

Open access Bayesian estimation of partial population continuity by using ancient DNA and spatially explicit simulations, by Silva et al., Evolutionary Applications (2018).
Abstract (emphasis mine):
The retrieval of ancient DNA from osteological material provides direct evidence of human genetic diversity in the past. Ancient DNA samples are often used to investigate whether there was population continuity in the settlement history of an area. Methods based on the serial coalescent algorithm have been developed to test whether the population continuity hypothesis can be statistically rejected by analysing DNA samples from the same region but of different ages. Rejection of

You might expect some rambling about bad journalism here, but I don’t have time to read so much garbage to analyze them all. We have seen already what they did with the “blackness” or “whiteness” of the Cheddar Man: no paper published, just some informal data, but too much sensationalism already.
Some people who supported far-fetched theories on Indo-European migrations or common European haplogroups are today sharing some weeping and gnashing of teeth around forums and blogs – although, to be fair, neither Olalde et al. (2018) nor Mathieson et al. (2018) actually gave any surprising new data … Read the rest “Reactionary views on new Yamna and Bell Beaker data, and the newest IECWT model”
A new paper appeared on Current Biology, by Margaryan et al. (including Morten E. Allentoft): Eight Millennia of Matrilineal Genetic Continuity in the South Caucasus.
Among its conclusions:
The plot clearly shows the clustering of the ancient group together with the modern European, Armenian, and Caucasian populations. We observe none of the typical East Eurasian mtDNA lineages (A, C, D, F, G, and M) among the ancient individuals, and only one individual with haplogroup D is present in the modern Armenian maternal gene pool (Artsakh). As such, the archaeologically and historically attested migrations of Central Asian groups (e.g., Turks
