From Highlands to Henge: Refining the Provenance and Transport Pathways of Stonehenge's Altar Stone

Journal of Quaternary Science, EarlyView.
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.

Marine Isotope Stage 4 glaciation in northern England, UK: Evidence from Victoria Cave, North Yorkshire

Journal of Quaternary Science, EarlyView.
ABSTRACT Victoria Cave, north Yorkshire, England, contains a long sequence of Pleistocene clastic sediments and calcite flowstones. Earlier work, using U–Th dating, established that the flowstone units formed in interglacial stages corresponding to Marine Isotope Stages (MIS) 13, 11, 9, 7 and 5.

Hydraulic reconstruction of catastrophic drainage from the Late Glacial, Lake Fraser, British Columbia, Canada

Journal of Quaternary Science, EarlyView.
ABSTRACT Glacial Lake Fraser, which formed in British Columbia against the retreating Cordilleran Ice Sheet, stored ~520 km3 of water before its near‐total drainage into the Salish Sea during an outburst flood event. Despite the impact of the outburst flood on sediment transport and landscape evolution in the Fraser River valley, its peak discharge and

Shared foraging behaviors between hyenas and hominins in the Middle Paleolithic Levant: New evidence from Geula Cave, Israel

Journal of Quaternary Science, EarlyView.
ABSTRACT While competition with large carnivores is likely to have shaped Middle Paleolithic hominins' subsistence behavior, palimpsested human and carnivore accumulations render the signal challenging to isolate. This study presents a detailed zooarchaeological and taphonomic analysis of a non‐anthropogenic faunal assemblage from a MIS 5 (~130–80 ka ...

Ferulic acid‐impregnated sodium alginate–pectin biopolymer film for active packaging and shelf‐life extension of potato chips

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND This study explores the development of active films incorporating ferulic acid (FA), a natural antioxidant, at concentrations of 0 (F1), 2.5 (F2), and 5 g L−1 (F3) into sodium alginate (SA; 13 g kg−1) and pectin (P; 10 g kg−1) matrix.
