Histological changes in the testicle of a calico cat

Veterinary Record Case Reports, Volume 14, Issue 1, February 2026.
Abstract A cat that presents orange and black colours (tortoiseshell), or all three colours (calico), is expected to be female since orange and black are colours related to the X chromosome, and white to the autosomal chromosomes. This study reported the case of an entire male calico cat.

Decreased PTGES2 Farnesylation in Granulosa Cells Compromises PGE2‐Dependent Cumulus Expansion and Oocyte Maturation During Ovarian Aging

Aging Cell, Volume 25, Issue 2, February 2026.
A schematic showing decreased PTGES2 farnesylation in granulosa cells compromises PGE2‐dependent cumulus expansion and oocyte maturation during ovarian aging. In young ovaries, PTGES2 farnesylation of GCs regulates the process of cumulus expansion and oocyte maturation by facilitating PGE2 production.

Improved taxonomic and gene sampling advance the knowledge of deep relationships within Macrodasyida (Gastrotricha)

Cladistics, Volume 42, Issue 1, Page 25-45, February 2026.
Abstract Advances in Macrodasyida (Gastrotricha) phylogenetics, fuelled by new species discoveries and molecular data, are reshaping taxonomic classifications. Molecular analyses suggest polyphyly in Cephalodasyidae and Macrodasyidae, yet insufficient sampling continues to obscure precise relationships.
