Life after herbarium digitisation: Physical and digital collections, curation and use

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1029-1041, July 2026.
Societal Impact Statement Collections of dried plant specimens (herbaria) provide an invaluable resource for the study of many areas of scientific interest and conservation globally. Digitisation increases access to specimens and metadata, enabling efficient use across a broad spectrum of research.

No evidence for Bergmann's rule in Otodus megalodon

open access: yesPapers in Palaeontology, Volume 12, Issue 4, July/August 2026.
Abstract It has been proposed that Otodus megalodon exhibits a Bergmann‐like size pattern, with individuals growing larger in cooler waters, an interpretation used to challenge the existence of fossil nursery assemblages. Here, we reanalyse the dataset used to support this claim, restricting analyses to upper anterior teeth to control for dental ...

Mercury isotopes to explore sources and fate of Hg in the environment: the case study of the Augusta Bay (southern Italy)

open access: yes, 2014
The Augusta Bay is a nearly closed marine basin located on the southeastern coast of Sicily (southern Italy) which has suffered, since the early 60s, the effect of the uncontrolled chemical discharge of Hg from the most important chlor-alkali plant in ...

Combined Effects of Arsenic and Cadmium With Selenium on Oxidative Stress Indicators in Goldfish: Implications for Veterinary Toxicology

open access: yesVeterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Co‐exposure to arsenic and cadmium alters metal accumulation and oxidative stress in goldfish. Selenium reduces arsenic bioaccumulation and lipid peroxidation while enhancing antioxidant defences. Findings highlight metal‐specific interactions, with selenium offering partial protection, emphasizing ecological risks and the importance of monitoring ...

Assessing the Worth of Noble Gas Tracer Concentrations in Alluvial River‐Aquifer Systems Using Data Space Inversion

open access: yesWater Resources Research, Volume 62, Issue 7, July 2026.
Abstract Alluvial systems are dynamic, structurally complex environments. Groundwater that is extracted from these systems is widely used for domestic consumption. Numerical models play an important role in the management of this extraction. To provide support for decision‐making, models must assimilate data that inform the spatial and temporal ...

Osmium Isotope and Highly Siderophile Element Constraints on the Cretaceous/Paleogene Boundary in Western Pacific Pelagic Clay

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract The Cretaceous/Paleogene (K/Pg) Chicxulub impact produced globally synchronous enrichments of highly siderophile elements (HSEs) and a pronounced decline in marine osmium isotope ratios (187Os/188Os), forming a key geochemical marker of the boundary.

Increasing the Acceptability of Insect‐Based Foods as Future Foods: A Comprehensive Review of Barriers, Strategies, and Pathways to Mainstream Adoption

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 4, July 2026.
ABSTRACT Edible insects are increasingly recognized for their high nutritional value and favorable environmental profile, yet their acceptance (defined as the continuum from willingness to try and purchase to repeated consumption) in Western and globalized food systems remains limited by cultural, sensory, regulatory, and economic barriers.
