Getting to the Core of the Matter—Assessing the Role of Replication in Metabarcoding‐Based sedaDNA

open access: yesMolecular Ecology Resources, Volume 26, Issue 7, October 2026.
ABSTRACT Replication is central to most experimental and sampling designs, increasing inferential power and capturing fine‐scale data heterogeneity. However, its importance remains poorly evaluated in some ecological and evolutionary settings. This is the case of metabarcoding studies using DNA recovered from sedimentary archives, in which biological ...

Characterization of a typical urban soil in terms of natural radionuclide content. The case study of a university campus

open access: yesHeliyon
A first comprehensive survey was carried out in a university campus in Italy in order to investigate in terms of natural elements an area where medium-high values of natural radiation are expected because of its peculiar geological features.

A Multi‐Analytical Approach for the Compositional Characterization and Chronological Discrimination of Benin (Nigeria) Metal Sculptures

open access: yesArchaeometry, Volume 68, Issue 5, Page 1022-1036, October 2026.
ABSTRACT This study presents a multi‐analytical archaeometric approach for the compositional characterization and chronological discrimination of Benin metal sculptures in relation to the 1897 Punitive Expedition. The methodology integrates elemental composition (XRF and ICP), stable lead isotope ratios (MC‐ICP‐MS) for alloy system characterization ...

Depositional processes of varved sediments from proglacial Lago Frías since 1800 CE (North Patagonian Andes, Argentina)

open access: yesBoreas, Volume 55, Issue 4, Page 1208-1227, October 2026.
The glacierized Valle Frías in Northern Patagonia is one of the best‐studied valleys in South America and includes varved sediments from Lago Frías. We complement this lacustrine record with a high‐resolution documentation of varve counts and their composition.

Controversies in NEN: An ENETS position statement on the role of liver transplantation (LT) in patients with advanced small‐intestinal and pancreatic NETs

open access: yesJournal of Neuroendocrinology, Volume 38, Issue 10, October 2026.
Abstract Liver transplantation (LT) may offer survival or symptomatic benefit for highly selected patients with advanced, well‐differentiated small‐intestinal or pancreatic neuroendocrine tumours and unresectable liver‐dominant metastases. However, its role remains controversial, as LT is rarely curative, recurrence is common, and benefits must be ...

Natural Radionuclides in Meadow and Pasture land in the Nordic countries [PDF]

open access: yes, 2012
The amount of natural radionuclides in the environment differs between the Nordic countries as shown by previous investigations and also by this study. Agricultural areas of high natural background are predominantly found in Sweden, Southern Finland and ...
