Experimental Evidence for Mobilization of Mercury From the Eggshell by the Developing Embryo in an Avian Model Organism

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Of the many pollutants wildlife is exposed to, mercury ranks among the most toxic. In birds, mercury does not only accumulate within generations, but also is transferred across generations via maternal offloading in eggs, with higher mercury concentrations found in shells of unhatched eggs.

Proteins of the Egg Shell

open access: yesPoultry Science, 1934
Abstract CALVERY 1 has shown that the protein of egg shell membranes has the amino acid composition of a typical keratin. An additional protein exists in the mineral portion of the shell and appears to serve as a matrix in which the inorganic salts are imbedded (Nathusius 2 ).

The Role of Oxophilicity and Water for Coordination Complexes as Ammonia Stores

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
Exposing metal salts to humid ammonia leads to different products, which can be understood on the basis of the metal’s oxophilicity. Exposing copper vitriol to ammonia furthermore leads to the formation of single crystalline [Cu(H2O)(NH3)4]SO4 at ambient conditions.

Male production in green sea turtles under a feminizing climate: A validated model of sex ratios with temperature‐dependent sex determination

open access: yesJournal of Animal Ecology, EarlyView.
This study introduces validated methods to predict sex ratios in wild Green sea turtle (Chelonia mydas) nests. It quantifies beach‐scale temperature heterogeneity, incorporates clutch‐level variation in thermal sensitivity and models temperature effects across the thermosensitive period, demonstrating how temporal temperature dynamics and spatial ...

The emergence and complexification of symbolic practices in the Homo lineage: an archaeological and cognitive perspective Émergence et complexification des pratiques symboliques dans la lignée Homo : une approche archéologique et cognitive

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
Recent archaeological discoveries, reviewed in this essay, challenge traditional views on the emergence of human symbolic cognition. Once believed to have originated in Europe around 40,000 years ago, new evidence shows it emerged much earlier across diverse regions.

‘The Housewife's Greatest Standby’: Dried Eggs, Gender and Domesticity During the Second World War

open access: yesGender &History, EarlyView.
ABSTRACT This article examines the previously underexplored connections between dried eggs, women and domesticity in Britain during the Second World War. It argues that newsprint and advertisements framed the purchase and use of dried eggs, a novel wartime product, as a means for housewives to contribute to the war effort through domestic labour. Dried
