A 3D Human Bone and Bone Marrow‐on‐a‐Chip Model for In Vitro Bone Remodeling and Immune Cell Maintenance

Advanced Science, EarlyView.
This study presents a human Bone (and Bone Marrow)‐on‐a‐Chip model based on native human bone scaffolds and autologous cells. Dynamic perfusion and sequential cell seeding replicate the physiological bone remodeling process in vitro, enabling the long‐term culture of functional, mature bone marrow immune subpopulations.

The Alps: glacial landforms from the Last Glacial Maximum

2022
The Alps were covered by a complex ice sheet comprised of various centers of glaciation with occasionally dome-like structures from which huge valley glaciers flowed out. Systems of transection (interconnected valley glaciers) as well characterized the Alps. The ELA across the Alps was between 1000 and 1700 m a.s.l., with a general trend of rising from

The Last Glacial Maximum

Science, 2009
The Melting Is in the Details Global sea level rises and falls as ice sheets and glaciers melt and grow, providing an integrated picture of the changes in ice volume but little information about how much individual ice fields are contributing to those variations.

Fennoscandia: glacial landforms prior to the Last Glacial Maximum

2022
Much of the pre-Last Glacial Maximum (LGM) geological record in Fennoscandia lies in sediment stratigraphic sequences. Indeed, early views of Fennoscandian glacial history (particularly for the pre-LGM period) were largely based on litho- and biostratigraphic correlations, while glacial landforms were considered to belong only to the last ice sheet ...

The Biological Pump During the Last Glacial Maximum

Annual Review of Marine Science, 2020
Much of the global cooling during ice ages arose from changes in ocean carbon storage that lowered atmospheric CO2. A slew of mechanisms, both physical and biological, have been proposed as key drivers of these changes. Here we discuss the current understanding of these mechanisms with a focus on how they altered the theoretically defined soft-tissue ...

The Pyrenees: glacial landforms from the Last Glacial Maximum

2022
The dimensions of Pyrenean glaciers at the time of the Last Glacial Maximum (LGM) interval (29–19 ka) are well established in the eastern part of the range, where 10Be and 36Cl exposure ages have been obtained from boulders embedded in moraines and from ice-scoured rock steps protruding from valley floors. By contrast, glacier dimensions at the time of

The Alps: glacial landforms prior to the Last Glacial Maximum

2022
Since the establishment of Penck and Brückner's four glaciations milestone theory, glacial studies in the Alps have represented a reference for the reconstruction of Pleistocene glaciations. The widespread preservation of pre-LGM glacial landforms, in particular the end-moraine systems and the related glaciofluvial stacks, allowed reliable ...

Last Glacial Maximum in Poland

Quaternary Science Reviews, 2002
Abstract The Last Glacial Maximum (LGM) in Poland is represented by the Leszno Phase and occurred after 21 ka radiocarbon years. In turn the deglacial Poznan Phase is estimated at 18.4 ka, the Pomeranian Phase at 15.2 ka, the Gardno Phase at about 14.0–13.8 ka, the Slupsk Bank Phase at 13.5–13.2 ka and the Southern Middle Bank Phase at 12.7–12.5 ka ...

The Last Glacial Maximum on Spitsbergen, Svalbard

Quaternary Research, 1992
AbstractMost scientists have concluded previously that the west coast of Spitsbergen, Svalbard, remained ice-free during the late Weichselian, between 25,000 and 10,000 yr B.P. We conclude that the glaciation was more extensive. Terraces that were postulated to have been ice-free are covered by a thin, late Weichselian till.
