Modulation of a sustained calcium current by intracellular pH in horizontal cells of fish retina. [PDF]
A sustained high voltage-activated (HVA), nifedipine- and cadmium-sensitive calcium current and a sustained calcium action potential (AP) were recorded from horizontal cells isolated from catfish retina.

Somewhere over the... what? [PDF]
In order to defend his controversial claim that observation is unaided perception, Bas van Fraassen, the originator of constructive empiricism, suggested that, for all we know, the images produced by a microscope could be in a situation analogous to that

The Imbalance of Nature: The Role of Species Environmental Responses for Community Stability
This study shows that the distribution of species' fundamental responses to environmental change, quantified by a new metric, imbalance, is a key driver of ecological stability. In a large microcosm experiment, lower imbalance predicted greater temporal stability, independently of species richness. Our findings highlight the predictive power of species'

When the path is never shortest: a reality check on shortest path biocomputation
Shortest path problems are a touchstone for evaluating the computing performance and functional range of novel computing substrates. Much has been published in recent years regarding the use of biocomputers to solve minimal path problems such as route ...

Animals and Fungi are Each Other's Closest Relatives: Congruent Evidence from Multiple Proteins [PDF]
Phylogenetic relationships among plants, animals, and fungi were examined by using sequences from 25 proteins. Four insertions/deletions were found that are shared by two of the three taxonomic groups in question, and all four are uniquely shared by ...

Study on the role of microtubules related to the nuclear behaviors during conjugation of paramecium caudatum [PDF]
In most organisms, microtubules are involved in the migration of the pronuclei during fertilization. Fertilization process of Paramecium caudatum includes two stages of nuclear migration. One is a selection of meiotic products.

The Mechanisms of Codon Reassignments in Mitochondrial Genetic Codes [PDF]
Many cases of non-standard genetic codes are known in mitochondrial genomes. We carry out analysis of phylogeny and codon usage of organisms for which the complete mitochondrial genome is available, and we determine the most likely mechanism for codon ...

Biodiversity modulates the cross‐community scaling relationship in changing environments
Organismal abundance typically declines with increasing body size, with metabolic theory predicting a universal size–abundance slope of –0.75. Using protist microcosms across gradients of species richness, temperature and time, we found that while the expected slope is broadly supported, it is not invariant. Warming and biodiversity interacted to alter

Comparative Genomic Analysis of Holospora spp., Intranuclear Symbionts of Paramecia
While most endosymbiotic bacteria are transmitted only vertically, Holospora spp., an alphaproteobacterium from the Rickettsiales order, can desert its host and invade a new one.

A signal transduction blind spot: the function of adenylyl cyclase transmembrane domains
Transmembrane adenylyl cyclases (tmACs) are essential for synthesising the universal second messenger cyclic AMP. All tmACs share a common topology that includes a large 12‐helix transmembrane (TM) domain. This domain accounts for ~ 35% of the coding sequence but its function is still an open question.
