Removal of Gadolinium Ions Using Modified Sea Sand Substrate From Water Environment and Impact of Ions on Gadolinium Replacement From Contrast MRI Agent

open access: yesNano Select, Volume 7, Issue 4, April 2026.
ABSTRACT Gadolinium in the form of complex compounds is used as a contrast agent in medicine diagnostic for magnetic resonance imaging. Gadolinium‐based contrast agents are divided into linear and macrocyclic substances in ionic or nonionic forms. Gd3+ toxic ions can be replaced from these compounds by cations such as Fe3+ and Cu2+. Gadolinium inhibits

Differences in Recycled Amendment Phosphorus Solubility and Transport When Interfaced to Soils of Dissimilar Characteristics

open access: yesSoil Use and Management, Volume 42, Issue 2, April‐June 2026.
ABSTRACT Increasing phosphorus (P) fertilizer use efficiency from bio‐based waste products (i.e., recycled amendments) requires promoting a larger proportion of bioavailable P in soil for plant uptake. Therefore, this study aimed to elucidate how recycled amendment P solubility and movement vary when interfaced with soils of contrasting characteristics.

The Great Microbiome Extraction Anomaly: How Extraction Bias Distorts Microbial Community Profiles

open access: yesEnvironmental DNA, Volume 8, Issue 2, March/April 2026.
Specimen chemistry and nucleic acid state (intracellular, host‐associated, adsorbed, extracellular) influence recovery. Extraction efficiency varies by microbial biology (e.g., reduced lysis of Gram‐positive bacteria). Even under consistent protocols, these factors systematically distort measured community composition relative to the true microbiome ...

Colonisation is a Determinant of Food (In)security: Findings from a Kaupapa Māori Study

open access: yesKōtuitui: New Zealand Journal of Social Sciences Online, Volume 21, Issue 1, March 2026.
This paper explores how the origins, ideologies and processes of colonisation have significantly disrupted and transformed Māori food systems in Aotearoa New Zealand. This paper builds on international Indigenous literature connecting colonisation, food insecurity and health outcomes, emphasising the need for policies and solutions grounded in ...

Float, explode or sink: postmortem fate of lung-breathing marine vertebrates [PDF]

open access: yes, 2018
What happens after the death of a marine tetrapod in seawater? Palaeontologists and neontologists have claimed that large lung-breathing marine tetrapods such as ichthyosaurs had a lower density than seawater, implying that their carcasses floated at the
