Tracing the evolutionary history of the morpho‐anatomy of baculum in primates

The Anatomical Record, EarlyView.
Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.

Investigating UAP Events Using Astronomical Techniques

Limina - The Journal of UAP Studies
The most important procedures about the scientific investigation of Unidentified Aerial Phenomena (UAP) using astronomy-like methods are conceptually presented and discussed, where results obtained in the past are triggering the proposal for new observational sessions using multiwavelength and multimode instruments.

Effects of Dietary Mannan Oligosaccharides on Growth, Disease Resistance, and Gut Microbiota in Zebrafish

Animal Research and One Health, EarlyView.
Supplementation with mannan oligosaccharides (MOS) enhances growth, disease resistance, antioxidant capacity, and gut microbiota diversity while suppressing inflammation, apoptosis, and strengthening intestinal barrier integrity in zebrafish challenged with LPS or DSS.

Principal Component‐Based Classification of Blazar Candidates of Uncertain Type in the 4FGL/LAT

Astronomische Nachrichten, EarlyView.
ABSTRACT We adopted principal component analysis (PCA), linear discriminant analysis (LDA), and support vector machines (SVM), to study classification for a sample of 2708 Fermi blazars: 1142 BL Lac objects (BLLs), 759 flat spectrum radio quasars (FSRQs), and 807 blazar candidates of uncertain type (BCUs).

The Inka Khipu and Yupana: A Reply to Zen Vasconcellos and Rojas Gamarra (2026)

Astronomische Nachrichten, EarlyView.
ABSTRACT A new analysis by Zen Vasconcellos and Rojas Gamarra offers a novel interpretation of the Inka devices used for calculating (yupana) and recording (khipu) numbers. They claim the Inka devices represented numbers neither positionally, with place value, as most researchers have assumed, nor additively, without place value, a possibility uniquely
