Demographic and zoological drivers of infectome diversity in companion cats with ascites

open access: yesmSystems
Cats (Felidae) have become an integral part of many households. However, our understanding of the full spectrum of pathogens affecting cats (referred to as the infectome) is limited, mainly due to the inadequacy of commonly used diagnostic tools in ...

Hydrostatic pressure activates HIF‐1α via β‐catenin to promote stemness in breast cancer cells

open access: yesFEBS Open Bio, EarlyView.
To mimic the elevated intestinal fluid pressure in breast cancers, we loaded human breast cancer cells (MCF‐7, MDA‐MB‐453, and BT‐474) to 50 mmHg hydrostatic pressure. Hydrostatic pressure exposure upregulated HIF‐1α and induced stemness in MCF‐7 and BT‐474 cells.

Bumblebees land rapidly by intermittently accelerating and decelerating toward the surface during visually guided landings

open access: yesiScience, 2022
Summary: Many flying animals parse visual information to control their landing, whereby they can decelerate smoothly by flying at a constant radial optic expansion rate.

Femtosecond‐Laser Mould Texturing Enables Tunable Biointerfaces in COC Microfluidics

open access: yesAdvanced Materials Interfaces, EarlyView.
Femtosecond‐laser texturing of injection‐mould inserts enables scalable engineering of biointerfaces in cyclic olefin copolymer microfluidics. Replicated micro‐ and nano‐topographies modulate surface roughness and wettability, leading to texture‐dependent protein adsorption and cell adhesion without chemical post‐processing.

Machine learning algorithms can predict emotional valence across ungulate vocalizations

open access: yesiScience
Summary: Vocalizations can vary as a function of their context of production and provide an immediate measure of an animal’s affective states. If vocal expression of emotions has been conserved throughout evolution, direct between-species comparisons ...

Use of ethnozoology and environmental education to unveilchildren's conception of anuran amphibians/Utilização da etnozoologia e educação ambiental para desvendar a concepção das crianças em relação aos anfíbios anuros

open access: yesDiversitas Journal, 2020
The absence of knowledge about anuran amphibians can lead to the banal extermination of species. Ethnozoology studies the relationship between human cultures over animals.

An appeasing pheromone ameliorates fear responses in the brown rat (Rattus norvegicus)

open access: yesiScience, 2023
Summary: The brown rat (Rattus norvegicus) is one of the major animals both in the laboratory and in urban centers. Brown rats communicate various types of information using pheromones, the chemicals that mediate intra-species communication in minute ...
