Co‐phylogeny and biogeography of the myrmecophilous beetle Paussus favieri (Carabidae, Paussinae) and its host ant Pheidole pallidula (Hymenoptera, Myrmicinae)

Insect Science, EarlyView.
Strict patterns of co‐divergence have rarely been documented other than among organisms and their symbionts. In this paper, using a molecular approach, we inferr the population‐level phylogenies of a Mediterranean ant species Pheidole pallidula and its nest parasite, the obligate myrmecophilous beetle Paussus favieri. We then investigate the role of co‐

‘But I can't preregister my research’: Improving the reproducibility and transparency of ecology and conservation with adaptive preregistration for model‐based research

Methods in Ecology and Evolution, EarlyView.
Abstract Preregistration is an open science practice which aims to improve research transparency and mitigate questionable research practices, like cherry‐picking results. It helps protect against cognitive biases, like hindsight bias, that can influence how study outcomes are interpreted.

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

Archaeometry, EarlyView.
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 ...

Brain natriuretic peptide and NT-proBNP levels reflect pulmonary artery systolic pressure in trekkers at high altitude. [PDF]

, 2013
Our objective was to evaluate the utility of the natriuretic peptides BNP (brain natriuretic peptide) and NT-proBNP as markers of pulmonary artery systolic pressure (PASP) in trekkers ascending to high altitude (HA). 20 participants had BNP and NT-proBNP

A Newly Discovered Tablet‐Making Facility in Nineveh: Insights From Scientific Analysis

Archaeometry, EarlyView.
ABSTRACT This paper addresses the question of tablet technology in the Neo‐Assyrian capital city of Nineveh. Recent excavations in the lower town of Nineveh by the Iraqi–Italian Archaeological Expedition uncovered an exceptional assemblage of more than 200 tablets from an elite residence that appears to have included a scriptorium.

What Is Space Bioethics?

Bioethics, EarlyView.
ABSTRACT Classical bioethics examines moral issues in terrestrial medicine and the life sciences. According to Konrad Szocik, space bioethics merely relocates those questions to harsher environments. We argue that this view is incomplete: space bioethics is a genuinely original domain.
