Localized and Transient Oxygenation of Shallow Oceans of Southwestern Laurentia at the Ediacaran-Cambrian Boundary. [PDF]

open access: yesGeobiology
ABSTRACT The Ediacaran–Cambrian boundary, which precedes one of the most significant biotic diversification events in Earth's history, is associated with a global negative carbon isotope excursion termed the BAsal Cambrian carbon isotope Excursion (BACE).

Photolysis of frozen iodate salts as a source of active iodine in the polar environment [PDF]

open access: yesAtmospheric Chemistry and Physics, 2016
Reactive halogens play a key role in the oxidation capacity of the polar troposphere. However, sources and mechanisms, particularly those involving active iodine, are still poorly understood.

Integration of molecular and computational approaches paints a holistic portrait of obscure metabolisms

open access: yesmBio, 2023
Microorganisms are essential drivers of earth’s geochemical cycles. However, the significance of elemental redox cycling mediated by microorganisms is often underestimated beyond the most well-studied nutrient cycles. Phosphite, (per)chlorate, and iodate

Iodine Biofortification of Apples and Pears in an Orchard Using Foliar Sprays of Different Composition

open access: yesFrontiers in Plant Science, 2021
Many people across the world suffer from iodine (I) deficiency and related diseases. The I content in plant-based foods is particularly low, but can be enhanced by agronomic biofortification.
