Quantitative micro‐XRF combined with X‐ray imaging reveals correlations between Zn concentration and dentin tubule porosity across entire teeth

open access: yesVIEW, EarlyView.
The combination of calibrated micro‐CT and quantitative micro‐XRF measurement facilitates the correlation of density and composition in the 3D macro‐structure of teeth. Zn concentration in dentin increases by a factor of 10 toward the pulp. Incidentally, the overall density decreases, showing an association between Zn and the dentin tissue porosity ...

Evaluating student involvement in sea‐level data rescue

open access: yesWeather, Volume 81, Issue 2, Page 52-59, February 2026.
Digitising historical tidal data are essential for tracking sea‐level rise and understanding long‐term climate trends. This study develops a framework to train undergraduate students in digitising tidal marigrams from Kilrush (County Clare) and Dún Laoghaire (County Dublin) Harbours. Students tackled challenges like misidentification, formatting errors

From dusk till dawn: ecoacoustic monitoring reveals wind energy impacts on roding Eurasian woodcock Scolopax rusticola

open access: yesWildlife Biology, EarlyView.
Renewable energy is vital for reducing carbon emissions and yet its infrastructure poses challenges to biodiversity. While the impacts of wind power on bats and raptors are well‐studied, the effects on elusive species remain largely unknown. The Eurasian woodcock Scolopax rusticola, a nocturnal forest bird, performs characteristic courtship flights at ...

Evaluation of drones as a tool for multi‐species nest surveys on linear rights‐of‐way

open access: yesWildlife Society Bulletin, EarlyView.
This paper examines the use of drones with infrared cameras as a tool in the detection of bird nests on linear rights‐of‐way, in comparison to standard ground‐based nest surveys. Abstract The varying application of drone use in wildlife research has expanded in recent years. With the ability to utilize a variety of different sensors (e.g., infrared [IR]
