Cuttlefish color change as an emerging proxy for ecotoxicology
Frontiers in Physiology, 2023 Lately, behavioral ecotoxicology has flourished because of increasing standardization of analyses of endpoints like movement. However, research tends to focus on a few model species, which limits possibilities of extrapolating and predicting ...

tRNA functional signatures classify plastids as late-branching cyanobacteria. [PDF]
, 2019 BackgroundEukaryotes acquired the trait of oxygenic photosynthesis through endosymbiosis of the cyanobacterial progenitor of plastid organelles. Despite recent advances in the phylogenomics of Cyanobacteria, the phylogenetic root of plastids remains ...

Energy conversion in Purple Bacteria Photosynthesis [PDF]
, 2011 The study of how photosynthetic organisms convert light offers insight not only into nature's evolutionary process, but may also give clues as to how best to design and manipulate artificial photosynthetic systems -- and also how far we can drive natural

Natural selection drove metabolic specialization of the chromatophore in Paulinella chromatophora
BMC Evolutionary Biology, 2017 Background Genome degradation of host-restricted mutualistic endosymbionts has been attributed to inactivating mutations and genetic drift while genes coding for host-relevant functions are conserved by purifying selection.

Direct Imaging of Protein Organization in an Intact Bacterial Organelle Using High-Resolution Atomic Force Microscopy [PDF]
, 2016 The function of bioenergetic membranes is strongly influenced by the spatial arrangement of their constituent membrane proteins. Atomic force microscopy (AFM) can be used to probe protein organization at high resolution, allowing individual proteins to ...

What Is It Like To Become a Bat? Heterogeneities in an Age of Extinction [PDF]
, 2018 In his celebrated 1974 essay “What Is It Like to Be a Bat?,” Thomas Nagel stages a human-bat encounter to illustrate and support his claim that “subjective experience” is irreducible to “objective fact”: because Nagel cannot experience the world as a bat

Squid adjust their body color according to substrate
Scientific Reports, 2022 Coleoid cephalopods camouflage on timescales of seconds to match their visual surroundings. To date, studies of cephalopod camouflage-to-substrate have been focused primarily on benthic cuttlefish and octopus, because they are readily found sitting on ...
