Rooftop Breeding Does Not Consistently Explain Variation in Yolk Testosterone in Herring Gulls

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
Rooftop‐ and ground‐breeding represent distinct ecological contexts that may influence maternal hormone allocation in Herring gulls. Yolk testosterone concentrations differed between rooftop‐ and ground‐breeding pairs in one of 2 years but were not consistently associated with breeding context, nest density or proxies of maternal quality, suggesting ...

Modelling growth of chick embryo: correction for egg weight [Modelowanie wzrostu zarodka kurzego z poprawką na masę jaja]

open access: yes, 1997
Prediction of embryo weight during incubation is of great interest in research on avian reproduction and choice of optimum hatching regimes. For this purpose the growth curves may be used.

Effects of oiling common raven nests on ravens and greater sage‐grouse in sagebrush ecosystems

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 7, September 2026.
We oiled and sham‐oiled raven nests across 7 sites in the Great Basin to measure the effects of egg‐oiling on co‐occurring populations of ravens and sage‐grouse. Oiling raven eggs ended embryonic development of oiled eggs, reduced raven densities, resulted in more than a doubling of nest‐survival probabilities of sage‐grouse nests, and spurred ...

Antitumor Activity of Combined Topoisomerase Inhibition and FLASH Radiotherapy in Head and Neck Carcinoma Biomodels

open access: yesMedComm, Volume 7, Issue 9, September 2026.
We report a proof‐of‐concept combination of topoisomerase inhibition and FLASH radiotherapy showing enhanced antitumor activity in head and neck carcinoma biomodels, supporting further investigation of this strategy in more clinically representative models and treatment settings. ABSTRACT Locally advanced head and neck carcinoma remains associated with

Impact of millimeter‐scale target motion on the precision of spatially fractionated radiation therapy using proton minibeams

open access: yesMedical Physics, Volume 53, Issue 9, September 2026.
Abstract Background While pencil beam scanning (PBS) with motion mitigation such as re‐scanning, breath hold, or gating is well established for treating moving targets in clinical practice, the precision for Spatially Fractionated Radiation Therapy (SFRT) using proton minibeams introduces presents a unique challenge.
