ABSTRACT During the last glacial period, the Laurentide Ice Sheet (LIS) was the largest terrestrial ice sheet on Earth. Its evolution since the Last Glacial Maximum profoundly influenced Earth's geodynamics and surface processes. Investigating the past dynamics of the LIS provides critical insights into how contemporary ice sheets may respond to ...

Abstract The Burren uplands in western Ireland form one of the most extensive and best‐preserved examples of glacio‐karst in Europe. Subsumed by the Irish ice sheet during the Late Pleistocene, granite erratic boulders and in situ silica veins in the limestone bedrock provide a rare opportunity to reconstruct the timing and rate of deglaciation ...

ABSTRACT Constraining Arctic catchment response to Holocene climate change is vital for understanding future environments. We present detailed sedimentological, geochemical and grain size end‐member analysis of two Holocene (~7.0 ka to present) lake sequences, S1 and S2, close to Zackenberg, Northeast Greenland.

ABSTRACT Like other perialpine basins and glaciated margins, the Geneva Basin in SW Switzerland is characterised by buried tunnel valleys, which are elongated incisions widely attributed to subglacial meltwater erosion beneath continental ice sheets. However, an inclusive understanding of the geological control on the evolution of the glacial landscape

From Highlands to Henge: Refining the Provenance and Transport Pathways of Stonehenge's Altar Stone
ABSTRACT The Altar Stone, the 6000 kg central sandstone megalith at Stonehenge in southern England, is suggested to have originated from the Orcadian Basin in northeast Scotland, some 700 km away. However, its source location within this large basin remains unresolved and its mode of transport uncertain.

Photooxidation of 18‐Carbon Polyunsaturated Fatty Acids to Prepare Mono‐Hydroxylated Octadecanoids
We developed a fast and simple one‐step synthetic strategy to produce mono‐hydroxylated metabolites based on the photosensitized oxidation of 18‐carbon polyunsaturated fatty acids (PUFAs). This approach could likely be extended to other PUFAs, suggesting that photosensitized oxidation could be employed to rapidly prepare hydroperoxides from multiple ...

When a Week Is Not A Week: How Temporal Boundaries Shift Regulatory Focus and Consumer Preference
ABSTRACT Does consumer perception of a sales event change if it falls across a calendar boundary (e.g., next month) versus within the current month, holding objective time constant? We investigate this question in the context of Cyber Monday, the global shopping event occurring the Monday after the U.S. Thanksgiving holiday.

We report here a new methodology to prepare functional poly(acetylene)s under aqueous conditions. This methodology is underpinned by poly(O‐propargyl‐N‐amino carbamate) (P1), a reactive poly(acetylene) carrying acyl hydrazines. Thus, P1 reacts with aldehydes to give functional poly(acetylene)s, including cationic, hydrophobic, and sugar‐loaded poly ...
