The effects of loose, firm, fine, and coarse substrates on the movement of the red flour beetle
Insect Science, Volume 32, Issue 2, Page 662-674, April 2025.The study focused on the impact of substrate roughness on movement properties, utilizing the red flour beetle as a model organism. Findings revealed significant variations in movement behavior between rough and smooth substrates, with beetles traveling longer distances on smooth surfaces compared to sandpaper and loose sand.

Rare Freshwater Ciliate Paramecium chlorelligerum Kahl, 1935 and Its Macronuclear Symbiotic Bacterium "Candidatus Holospora parva". [PDF]
PLoS ONE, 2016 Ciliated protists often form symbioses with many diverse microorganisms. In particular, symbiotic associations between ciliates and green algae, as well as between ciliates and intracellular bacteria, are rather wide-spread in nature.

Interaction of the mechanosensitive microswimmer Paramecium with obstacles
Royal Society Open Science, 2023 In this work, we report investigations of the swimming behaviour of Paramecium tetraurelia, a unicellular microorganism, in micro-engineered pools that are decorated with thousands of cylindrical pillars.

From Biosemiotics to Semiotics [PDF]
, 2002 Biosemiotics and Semiotics have similarities and differences. Both deal with signal and meaning. One difference is that Biosemiotics covers a domain (life) that is less complex that the one addressed by Semiotics (human).

Low-Reynolds number swimming in a capillary tube [PDF]
, 2013 We use the boundary element method to study the low-Reynolds number locomotion of a spherical model microorganism in a circular tube. The swimmer propels itself by tangen- tial or normal surface motion in a tube whose radius is on the order of the swimmer size.

Advanced Science, Volume 12, Issue 12, March 27, 2025.Fluorescence resonance energy transfer‐based sensor zebrafish are generated to visualize muscle cell apoptosis in live animals by color change from green to blue. Using these sensors zebrafish, starvation‐induced, or natural aging‐induced muscle atrophy models are established. The diameters of muscle cells decrease in both models; however, muscle cells

Protention and retention in biological systems [PDF]
, 2011 This paper proposes an abstract mathematical frame for describing some features of cognitive and biological time. We focus here on the so called "extended present" as a result of protentional and retentional activities (memory and anticipation).

Evolution &Development, Volume 27, Issue 1, March 2025.Hybrid Danionin embryos undergo normal developmental transitions until 1‐day postfertilization (dpf), where inter‐genera hybrids exhibit gastrulation defects. Despite juvenile growth variability hybrids reach adulthood, with males showing reduced fertility and abnormal sperm morphology. Only D. rerio x D.

BMC Evolutionary Biology, 2009 Background The sub-membranous skeleton of the ciliate Paramecium, the epiplasm, is composed of hundreds of epiplasmic scales centered on basal bodies, and presents a complex set of proteins, epiplasmins, which belong to a multigenic family.
