Macroanatomical, Histological, Histochemical and Ultrastructural Characterisation of the Kidney in the Aksaray Malakli Dog: First Comprehensive Renal Morphological Study of the Breed

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
This study provides the first comprehensive macroanatomical, histological, histochemical and scanning electron microscopic characterisation of the kidney in the Aksaray Malaklı dog. Key findings include normal canine renal architecture, absence of acidic polysaccharides, PAS‐positive basement membranes, and a previously unreported breed‐specific ...

An Operational Daily‐Filtered Dominion Radio Astrophysical Observatory F10.7 cm Solar Radio Flux Product

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract The F10.7 solar radio flux density, or F10.7, is a disk‐integrated measure of the Sun's total emission at 10.7 cm (2.8 GHz) and is a widely‐used proxy of solar activity. F10.7 emissions primarily originate from the Sun's upper chromosphere and lower corona. High‐frequency, transient “radio bursts” can dramatically increase the magnitude of F10.

Statistical Scale Analyses of a Diurnal Periodicity in Auroral Kilometric Radiation, Observed by Wind/WAVES

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract The Earth's strongest natural radio emission is Auroral Kilometric Radiation (AKR), which is correlated with auroral intensity, and is a barometer for space weather. AKR is generated by the electron cyclotron maser instability, with sources on auroral field lines. Previous work on AKR and radio emissions from other planets (or stars) points to

Iono‐PhyTAU: A Lightweight Global Ionospheric TEC Prediction Model Based on Temporal Attention Unit and Physical Condition Constraints of the Ionosphere

Space Weather, Volume 24, Issue 9, September 2026.
Abstract Ionospheric Total Electron Content (TEC) is the primary error source causing signal delay in Global Navigation Satellite Systems (GNSS). High‐precision TEC prediction is essential for positioning, navigation, and space weather monitoring. Although deep learning models including ConvLSTM, ConvGRU, and Transformer have advanced TEC forecasting ...

Did Space Weather Delay the 10:05 p.m. Train Departure From Exeter on 18 October 1841?

Space Weather, Volume 24, Issue 9, September 2026.
Abstract Although the Carrington Event of 1859 is typically cited as the first extreme space weather event of the scientific era, it is not the earliest example of modern human technology being impacted by geomagnetic activity. The literature includes reliable accounts of disturbances to telegraph equipment during geomagnetic storms dating to the late ...
