Sedimentary ancient DNA from caves: Challenges and opportunities

Journal of Quaternary Science, Volume 40, Issue 4, Page 565-578, May 2025.
Abstract Caves are unique depositional environments that hold great potential for long‐term preservation of DNA due to their typically cool and stable internal climates, buffered from external climate extremes. Bones from caves have long been recognised as an excellent source of ancient DNA, yet the potential for DNA preservation in cave sediments ...

RED JASPEROIDS FROM THE AREA OF THE UKRAINIAN ANTARCTIC RESEARCH STATION

Geological Journal
Red jasper-like rocks from the area of the Akademik Vernadsky Station are known since the time of the first Ukrainian Antarctic expeditions. But until now, all the published information about them was limited to only one brief mention in the abstract of the report by Mytrokhyn and Bakhmutov (2017). This article summarizes all available data about these
