Nesting ecology of an ice‐associated seabird, Kittlitz's murrelet, at the northern edge of its range

Wildlife Society Bulletin, Volume 50, Issue 3, September 2026.
We studied the Kittlitz's murrelet, an ice‐associated seabird of conservation concern, at the northern edge of its range. Over a 2‐year period, we estimated nest density and success at 2 sites, captured and telemetered nesting murrelets, and tested the use of a thermal camera to improve nest detection.

The AO327 Drift Survey Catalog and Data Release of Pulsar Detections

The Astrophysical Journal Supplement Series
The AO327 drift survey for radio pulsars and transients used the Arecibo telescope from 2010 until its collapse in 2020. AO327 collected ∼3100 hr of data at 327 MHz with a time resolution of 82 μ s and a frequency resolution of 24 kHz.

Analysis of the fast optical variability and flaring activity of the transitional millisecond pulsar PSR J1023+0038

, 2022
openSi ritiene che le millisecond pulsar (MSP) siano stelle di neutroni piuttosto vecchie ed in rapida rotazione, formate in sistemi binari e accelerate fino a periodi di rotazione dell'ordine del millisecondo durante una fase di accrescimento dalla ...

Intracerebroventricular injection of neuropeptide Y suppresses luteinizing hormone pulses in mice

Journal of Neuroendocrinology, Volume 38, Issue 9, September 2026.
Abstract Stress impairs reproduction, at least in part, by inhibition of Kisspeptin/Neurokinin B/Dynorphin (KNDy) cells and suppression of gonadotropin secretion. However, the mechanism for this inhibition is not clear. Neuropeptide Y (NPY) is a pleiotropic molecule that is produced in neurons throughout the brain and mediates several physiological ...

Unusual flux-distance relationship for pulsars suggested by analysis of the Australia national telescopy facility pulsar catalogue [PDF]

, 2009
We analyze pulsar fluxes at 1400 MHz (S(1400)) and distances d taken from the Australia National Telescope Facility (ATNF) Pulsar Catalogue. Under the assumption that pulsar populations in different parts of the Galaxy are similar, we find that either (a)

Iron‐Substituted Zn‐Al LDH‐Derived Mixed Oxides: Tailoring Structure, Composition and Redox Properties for Efficient CO2‐to‐Olefins Conversion

ChemCatChem, Volume 18, Issue 15, 14 August 2026.
LDH‐derived Zn‐Fe‐Al mixed oxides exhibited 40% CO2 conversion and 10.6% yield of light olefins. The composition and the properties of the mixed oxides strongly influenced the selectivity of products, while ZnFe2O4 and iron carbide structure promoted the conversion and the selectivity of light olefins.

Comparison of prostatic urethral lift (PUL) versus water vapour thermal therapy (WVTT): A focus on drug‐free status and unplanned admissions

BJUI Compass, Volume 7, Issue 7, July 2026.
Abstract Objectives To compare prostatic urethral lift (PUL) and water vapour thermal therapy (WVTT) for benign prostatic hyperplasia (BPH) in a real‐world setting, this study compares clinical management outcomes that are less thoroughly documented in current literature—such as drug‐free status, complications and post‐procedure readmission rates ...

A living biobank of sarcoma patient‐derived cell cultures reveals multi‐omic and functional insights that capture disease heterogeneity

Clinical and Translational Medicine, Volume 16, Issue 7, July 2026.
Preclinical models for sarcoma that preserve tumour biology are urgently needed to advance mechanistic understanding and functional precision oncology. 29 early‐passage patient‐derived sarcoma cell (PDC) cultures from 19 patients, representing 11 sarcoma subtypes were established and extensively characterized.

A New X-Ray Census of Rotation Powered Pulsars

The Astrophysical Journal
To date, over 4000 pulsars have been detected. In this study, we identify 231 X-ray counterparts of Australia Telescope National Facility (ATNF) pulsars by performing a spatial cross match across the Chandra, XMM-Newton observational catalogs.

Tuning the Geometric and Electronic Structures in PtMn/SiO2 Catalysts via Oxygen Plasma Treatment for Enhanced Propane Dehydrogenation

Carbon and Hydrogen, Volume 28, Issue 2, Page 184-195, June 2026.
Oxygen plasma treatment promotes Pt dispersion, reducing the average Pt particle size of PtMn catalyst from 2.7 to 1.2 nm, and increases the electron cloud density of Pt. The optimized catalyst exhibits excellent mass‐normalized activity (171 molC3H8·gPt−1·h−1) and an ultralow deactivation rate constant, outperforming most reported Pt‐based catalysts ...
