Climate deteriorations and Neanderthal demise in interior Iberia

Scientific Reports, 2018
Time and circumstances for the disappearance of Neanderthals and its relationship with the advent of Modern Humans are not yet sufficiently resolved, especially in case of the Iberian Peninsula.

Spatio-temporal dynamics of speleothem growth and glaciation in the British Isles [PDF]

Climate of the Past
Reconstructing the spatio-temporal dynamics of glaciations and permafrost largely relies on surface deposits and is therefore a challenge for every glacial period older than the last due to erosion.

Population structure of chum salmon (Oncorhynchus keta) across the Pacific Rim, determined from microsatellite analysis [PDF]

, 2009
The Pacific Rim population structure of chum salmon (Oncorhynchus keta) was examined with a survey of microsatellite variation to describe the distribution of genetic variation and to evaluate whether chum salmon may have originated from two or more ...

Sea surface temperature changes in the southern California borderlands during the last glacial-interglacial cycle [PDF]

, 1996
A variety of evidence suggests that average sea surface temperatures (SSTs) during the last glacial maximum in the California Borderlands region were significantly colder than during the Holocene.

Improving chronological control for environmental sequences from the last glacial period [PDF]

Quaternary Geochronology, 2018
Recognition of palaeoclimatic instability in the Greenland ice cores has spurred researchers to identify corresponding evidence in other terrestrial records from the last glacial stage. Such evidence is critical for establishing how much environmental stress precipitated Neanderthal and Late Pleistocene megafaunal extinctions, although a need for ...

Differential regulation of ZFAS1 splice variants by endoplasmic reticulum stress in hepatocyte cell lines

FEBS Open Bio, EarlyView.
ZFAS1 is a lncRNA promoting cell proliferation and migration, exhibiting high expression in various cancers. It is conserved, widely expressed, and produces multiple splice variants with unclear roles. We identified several splice variants in hepatocyte models, and found that inhibiting or suppressing regulators of the unfolded protein response (PERK ...

The De Long Trough: a newly discovered glacial trough on the East Siberian continental margin [PDF]

Climate of the Past, 2017
Ice sheets extending over parts of the East Siberian continental shelf have been proposed for the last glacial period and during the larger Pleistocene glaciations.

Variable sequence of events during the past seven terminations in two deep-sea cores from the Southern Ocean [PDF]

, 2012
The relationships among internally consistent records of summer sea-surface temperature (SSST), winter sea ice (WSI), and diatomaceous stable isotopes were studied across seven terminations over the last 660 ka in sedimentary cores from ODP sites 1093 ...

MiR‐513a promotes human erythroid differentiation by modulating c‐Jun

FEBS Open Bio, EarlyView.
During early human erythropoiesis, miR‐513a promoted erythroid differentiation in primary human CD34+ hematopoietic stem‐progenitor cells and human TF‐1 erythroleukemic cells by indirectly decreasing c‐Jun and phospho‐c‐Jun expression, which are associated with increased GATA1 expression.

Identification of Potential Paleoislands in the Mediterranean Sea During the Last Glacial Cycle

European Journal of Geography
The Last Glacial Period (LGP) significantly altered sea levels and landscapes across the globe, with the Mediterranean Sea being no exception. During this period, fluctuating sea levels exposed numerous landmasses, some of which may have served as ...
