Ritualized ink use during visual courtship display by males of the sexually dimorphic cuttlefish Sepia andreana

open access: yesEcology and Evolution, Volume 14, Issue 2, February 2024.
Cephalopods may release ink when attacked by predators, but we have discovered that ink is used as a part of the courtship display by males of the cuttlefish species Sepia andreana. Males of this species engage in a highly ritualized multi‐modal courtship using a pair of markedly long sexually dimorphic arms, and at the climax of the courtship, the ...

Melanin-like Nanoparticles Boosted the Photoprotective Efficiency and Stability of Sanshool

open access: yes, 2023
Sanshool, a naturally occurring molecule from Zanthoxylum xanthoxylum, is an essential component preventing photodamage; however, inherent instabilities and the potential risk of skin permeation limit its further application.
