Zinc (Zn) isotope fractionation by the coccolithophore Emiliania huxleyi (a Tasman Sea isolate) was investigated by culturing it across a range of free Zn2+ ion concentrations (1.2 pmol L−1 to 3.2 ...
A new study published on October 17 th in the journal PNAS, led by a CNRS researcher, has for the first time used zinc isotope analysis to determine the position of Neanderthals in the food chain.
This was a cross-sectional study, which compared zinc homeostasis between premature infants fed either PTF or HM+HMF. Stable zinc isotopes were administered intravenously and orally on d 1; 3 d later, ...
Zinc deficiency is estimated to account for 4.4% of child deaths worldwide, and one-third of the world's children are at risk for zinc deficiency (1). The morbidity associated with zinc deficiency ...
Paleodietary studies of the fossil record are impeded by a lack of reliable and unequivocal tracers. Scientists have now tested a new method, the isotope analysis of zinc isotopes from the tooth ...
Researchers used the teeth of 13 megalodon sharks and 20 modern great white sharks to analyze dietary signatures and their trophic levels or where they fit in the food chain. (Pictured: a megalodon ...
For the first time, zinc isotope ratios in tooth enamel have been analysed with the aim of identifying the diet of a Neanderthal. The Neanderthal to whom the tooth belonged was probably a carnivore.
