Cytogenotoxic and Molecular Assessment of Pyrethrins on Non‐Target Allium cepa Roots

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT The pyrethrins, which form a part of naturally occurring insecticidal chemicals derived from chrysanthemum flowers, not only provide rapid knockdown of a broad spectrum of insect pests but are also widely used in integrated pest management due to a generally favorable safety profile, largely attributed to low mammalian toxicity.

Tail wagging cats: Veterinary implications of AI‐generated video

open access: yesVeterinary Record, EarlyView.
Abstract Background Generative artificial intelligence (genAI) has the capacity to create realistic and convincing animal videos; however, it must simplify and reduce behavioural variation to do so, possibly leading to misinformation. Methods We categorised 29 videos in the press release for a specific video genAI engine. Twelve featured animals.

Quantitative collagen and proteoglycan imaging reveal organic layering, gradients and regional texture in young mature dental cementum

open access: yesVIEW, EarlyView.
Cementum, the mineralized tissue covering all mammalian tooth roots, helps maintain tooth stability, but its internal organization is still poorly understood. In this study, we combine quantitative histologial methods to map the regional distributions of collagen fibers and proteoglycan‐rich matrix layers in porcine cementum.

How weather got its words: a history of meteorological English – Part 2: the scientific age and beyond

open access: yesWeather, EarlyView.
The English language is a gargantuan, gluttonous beast. It has become extraordinary in its powers of assimilation – such that we rarely consider the origins of the words we use. In this paper, we will shed light on these origins, including the Pontic–Caspian steppe, the British Empire and, of course, a TV show.
