Trajectories of adoption for silver and bloomery iron in China from the Spring and Autumn period (c. 770–476 BC)

Archaeometry, EarlyView.
Abstract We examine the number of sites with silver objects in China over a period of 3500 years to suggest that technologies that stimulated the indigenous exploitation of silver‐bearing ores were innovated during the Spring and Autumn period (c. 770–476 BCE), and that increased centralisation and bureaucratisation from the Warring States period (475 ...

The Mg/Fe ratio of silicate minerals in the meteoritic materials and in the circumstellar environment: A case study for the chondritic-like composition

Open Astronomy, 2021
Kaba meteorite as a reference material (one of a least metamorphosed and most primitive carbonaceous chondrites fell on Earth) was chosen for this study providing an adequate background for study of the protoplanetary disk or even the crystallization ...

The morphosedimentary record of glacial to postglacial environmental changes in West Wiyâshâkimî impact crater lake and adjacent areas, northern Québec, Canada

Boreas, EarlyView.
Crater lakes in core regions of former ice sheets have the potential to preserve long‐term sedimentary archives that are otherwise rare in glaciated landscapes due to pervasive glacial erosion. Lake Wiyâshâkimî, an impact crater lake located in the inner core of the Québec‐Labrador Dome of the Laurentide Ice Sheet, provides a rare example of such a ...

d‐amino acids: new functional insights

The FEBS Journal, EarlyView.
This review explores recent advances in understanding d‐amino acids (d‐AAs) and their pivotal roles across organisms, from plants to humans. d‐AAs have been implicated in key physiological processes, including cancer, inflammation, immune regulation, kidney disease, diabetes, and nervous system function.

Thermal Alteration of Labile Elements in Carbonaceous Chondrites

, 2018
Carbonaceous chondrite meteorites are some of the oldest Solar System planetary materials available for study. The CI group has bulk abundances of elements similar to those of the solar photosphere.
