Ancient DNA reveals the prehistory of the Uralic and Yeniseian peoples - Nature
Genome-wide sequencing of 180 ancient individuals shows a continuous gradient of ancestry in Early-to-Mid-Holocene hunter-gatherers from the Baltic to the Transbaikal region and distinct contemporaneous groups in Northeast Siberia, and provides insights into the origins of modern Uralic and Yeniseian speakers.

We had built something conceptually similar using the front lens on an ICR (or adjacent quad segments) in a segmented PCB quad to trap ions between the LIT and ICR cell on our development instrument to improve trapping for short ICR array cells. Nightmarish to optimize timings, very impressive work
