Cirque Glacier on South Georgia Shows Centennial Variability over the Last 7000 Years

Frontiers in Earth Science, 2018
A 7000 year-long cirque glacier reconstruction from South Georgia, based on detailed analysis of fine-grained sediments deposited downstream in a bog and a lake, suggests continued presence during most of the Holocene.

Origin, evolution and biogeographic dynamics of the European rabbit (Oryctolagus cuniculus) in Southwestern Europe

The Anatomical Record, EarlyView.
Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

New techniques for old bones: Morphometric and diffeomorphometric analysis of the bony labyrinth of the Reilingen and Ehringsdorf Neandertals

The Anatomical Record, EarlyView.
Abstract Neandertals are known to possess very distinctive traits in their bony labyrinth morphology, such as an inferiorly positioned posterior canal and a very low number of turns in the cochlea. Hence, the inner ear has been often used to assess the Neandertal status of fragmentary fossils.

Diverse drought responses and evidence for stress priming in glacier-fed stream bacteria

Frontiers in Microbiology
Microorganisms inhabiting dynamic ecosystems are repeatedly exposed to environmental fluctuations and disturbances which require physiological adaptations, often associated with fitness trade-offs.

History of Alibek Glacier based on Earth remote sensing images, bioindication and cosmogenic isopotes (14С and 10Be)

Лëд и снег, 2015
In this article we present the reconstruction of fluctuations of Alibek valley glacier situated in the Teberda valley, Western Caucasus. The former positions of glacier of the past 120 years were reconstructed basing on the old photographs of 1904, 1921,

Does salinity make a difference—Kidney anatomy of Saimaa (Pusa saimensis) and Baltic ringed seals (Pusa hispida botnica)

The Anatomical Record, EarlyView.
Abstract As habitat salinity markedly differs between the endangered, freshwater‐dwelling Saimaa ringed seal (Pusa saimensis Nordquist, 1899) and the brackish water‐inhabiting Baltic ringed seal (Pusa hispida botnica Gmelin, 1788), we investigated whether this difference has resulted in morphological changes to their kidneys.

A Practical Gut‐On‐Chip Workflow for Imaging‐Based Assessment of Epithelial Barrier Dynamics During E. coli Co‐Culture

Biotechnology and Bioengineering, EarlyView.
ABSTRACT The intestinal epithelium and its resident microbiota form a dynamic interface that is central to gut homeostasis, but this interface is difficult to model with conventional tools. Static Transwell cultures lack physiological fluid shear, whereas animal models are costly and poorly suited to quantitative, high‐content imaging.

Temporal glacier velocity variations and their controlling factors in the Nathorstbreen glacier system, Svalbard

Egyptian Journal of Remote Sensing and Space Sciences
Temporal variations in glacier velocity are not only essential to understand glacier dynamics but also to predict glacier hazards. Therefore, in the current study, the continuous glacier velocities were estimated from 2014 to 2023 in the Nathorstbreen ...

Magnetoelastic Cell Monitoring System for Evaluating the Effects of Surface Chemistry on the Performance of Mesenchymal Stem Cell Growth

Biotechnology and Bioengineering, EarlyView.
ABSTRACT The recent clinical adoption of cell therapies has increased the need for more efficient, robust, and reproducible manufacturing technologies. Human mesenchymal stromal cells (hMSCs), a major component of the cell and immunotherapeutic market, remain challenging to manufacture at scale because they require surface attachment and are highly ...
