The role of Beringia in human adaptation to Arctic conditions based on results of genomic studies of modern and ancient populations by B. A. Malyarchuk

“…The results of studies in Quaternary geology, archeology, paleoanthropology and human genetics demonstrate that the ancestors of Native Americans arrived in mid-latitude North America mainly along the Pacific Northwest Coast, but had previously inhabited the Arctic and during the last glacial maximum were in a refugium in Beringia, a land bridge connecting Eurasia and North America. …”

The surface tension and cloud condensation nuclei (CCN) activation of sea spray aerosol particles by J. Kleinheins, N. Shardt, U. Lohmann, C. Marcolli

“…In a sensitivity study we show that organic compounds can be categorized into weak, intermediate, and strong surfactants for CCN activation based on their separation factor in water <span class="inline-formula"><i>S</i>_1<i>i</i></span> and their pure component surface tension <span class="inline-formula"><i>σ</i>_<i>i</i></span>. For a quaternary model system of SSA particles, it is shown that high content of hydrophobic organic material (i.e. strong surfactants) in Aitken mode particles does not necessarily prevent good CCN activation but rather facilitates effective activation via surface tension lowering. …”

Genomic signatures of habitat isolation and paleo-climate unveil the “island-like” pattern in the glasshouse plant Rheum nobile by Hum Kala Rana, Santosh Kumar Rana, Hang Sun, Dong Luo

“…The “island-like” genetic patterns of Rheum nobile results from fragmented habitats and prolonged isolation during the Quaternary glaciation. This study highlights the species’ evolutionary trajectory shaped by ecological adaptation, and climatic fluctuations, providing valuable insights for future conservation and management efforts in its native environment.…”

Characteristics and mechanism of MBT anomaly of Karakum desert related with the Hindu Kush earthquake by Yifan Ding, Ziqing Wang, Yuan Qi, Wenfei Mao, Qiqi Zhang, Lixin Wu

“…The upward transfer of P-hole particles, activated in the deep hypocenter area by accumulated crustal stress during the pre-, co- and after-EQ period, to the Quaternary surface along the stress gradient, was believed to have reduced the local ground surface dielectric constant and amplified the microwave radiation, which leading subsequently to the positive MBT anomalies. …”
