New paper (behind paywall) Ancient genomes suggest the eastern Pontic-Caspian steppe as the source of western Iron Age nomads, by Krzewińska et al. Science (2018) 4(10):eaat4457.
Interesting excerpts (emphasis mine, some links to images and tables deleted for clarity):
Late Bronze Age (LBA) Srubnaya-Alakulskaya individuals carried mtDNA haplogroups associated with Europeans or West Eurasians (17) including H, J1, K1, T2, U2, U4, and U5 (table S3). In contrast, the Iron Age nomads (Cimmerians, Scythians, and Sarmatians) additionally carried mtDNA haplogroups associated with Central Asia and the Far East (A, C, D, and M). The absence of East Asian mitochondrial

Open access Differing modes of animal exploitation in North-Pontic Eneolithic and Bronze Age Societies, by Mileto, Kaiser, Rassamakin, Whelton & Evershed, STAR (2018). You can download the PDF.
Abstract (emphasis mine)
This paper presents new results of an interdisciplinary investigation of the diet and subsistence strategies of populations living in the North-Pontic region during the Eneolithic and the Early Bronze Age (ca. 3800 BC to the 2500 BC). New organic residue analyses of 200 sherds from five Eneolithic sites and two Early Bronze Age settlements are presented. The molecular and stable isotope results are discussed in relation to

A new paper with open access has appeared in Quaternary Science Reviews, authored by Patton et al.: Deglaciation of the Eurasian ice sheet complex, which offers a new model investigating the retreat of this ice sheet and its many impacts.
According to the comments of professor Alun Hubbard, the paper’s second author and a leading glaciologist:
To place it in context, this is almost 10 times the current rates of ice lost from Greenland and Antarctica today. What’s fascinating is that not all Eurasian ice retreat was from surface melting alone. Its northern and western sectors across the
