A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

The Anatomical Record, Volume 309, Issue 9, Page 2315-2330, September 2026.
Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...

Volcanic Eruptions Reorganize Climate Teleconnections: Detection via Riemannian Covariance Fingerprinting

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Standard detection and attribution of volcanic forcing targets spatial temperature anomalies. We show that the covariance structure of climate variability carries an independent volcanic fingerprint. Applying tangent‐space regression on the symmetric positive definite manifold SPD(8) to 40 years of eight teleconnection indices, we detect ...

A Lightweight and Erudite Automated BiLSTM‐Based Multi‐Cycle GAN for Retinal Blood Vessel and Optic Disc Segmentation in Fundus Images

Engineering Reports, Volume 8, Issue 8, August 2026.
This graphical abstract presents a lightweight and automated BiLSTM‐based Multi‐Cycle GAN framework for retinal blood vessel and optic disc segmentation in fundus images. Initially, fundus images undergo preprocessing, including green channel extraction, denoising, resizing, and dataset splitting.

Eriope barrinhae (Lamiaceae, Hyptidinae), a new montane species from northern Minas Gerais, Brazil

Nordic Journal of Botany, Volume 2026, Issue 8, August 2026.
In northern Minas Gerais, in the Monte Azul region, the Pico da Formosa mountain remains poorly explored botanically despite recent discoveries of new taxa. During fieldwork at the summit of this mountain, we discovered a distinctive population of Eriope that differs from all known species by a unique combination of morphological characters.

Statistical study of the equatorial F2 layer critical frequency at Ouagadougou during solar cycles 20, 21 and 22, using Legrand and Simon’s classification of geomagnetic activity

Journal of Space Weather and Space Climate, 2012
This paper presents the statistical analysis of the diurnal variations of the F layer at the equatorial station of Ouagadougou (Lat: 12.4° N; Long: 358.5° E; dip: 5.9°) from 1966 to 1998 (=> ~11 680 days).

Investigation of HZE particle fluxes as a space radiation hazard for future Mars missions

Heliyon, 2019
Manned Mars missions planned in the near future of very low solar activity period and hence higher than acceptable radiation doses due mainly to the Galactic Cosmic Rays (GCR), would require special techniques and technological development for ...

Near‐Earth Solar Wind Speed of Fast Coronal Mass Ejections

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Using solar wind and ground magnetometer data for solar cycles 23–25, extreme‐value power‐law models are developed that quantify relationships between near‐Earth solar wind speed and Sun‐to‐Earth transit times of interplanetary coronal mass ejections (ICMEs).

Latitude Survey of Neutrons and Muons to Determine Cosmic Ray Neutron Sensing Yield Functions

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Cosmic Ray Neutron Sensing (CRNS) is a ground‐based technique that utilizes epithermal neutron measurements as a proxy for environmental hydrogen content. Similarly to other ground‐based cosmic ray detectors (e.g., neutron monitors), CRNS detectors are affected by the solar cycle and space weather events.
