A rapidly expanding house of cards: the silent loss of cell physiology hampers marine biosciences

Frank Melzner, Imke Podbielski, Felix C Mark, et al.

Perspective: An ongoing loss of expertise on the biochemistry and physiology of marine organisms hampers our understanding of biological mechanisms upon rapidly growing “-omics” approaches reply -ultimately affecting our ability to predict organismal responses to climate change.

Computational Modeling and Evolutionary Implications of Biochemical Reactions in Bacterial Microcompartments

Clair A. Huffine, Lucas Wheeler, Boswell Wing, et al.

Subjects: Biochemistry, Biochemistry, Biophysics, and Structural Biology, Biology, Life Sciences

Bacterial microcompartments (BMCs) are protein-encapsulated compartments found across at least 23 bacterial phyla. BMCs contain a variety of metabolic processes that share the commonality of toxic or volatile intermediates, oxygen-sensitive enzymes and cofactors, or increased substrate concentration for magnified reaction rates. These compartmentalized reactions have been computationally modeled [...]

On May 16, 2020, the Center for Academic Research and Training in Anthropogeny organized the symposium “Impact of Infectious Disease on Humans and Our Origins”. The symposium aimed to gather experts on infectious diseases in one place and discuss the interrelationship between different pathogens and humans in an evolutionary context. The talks discussed topics including SARS-CoV-2, dengue and [...]

Epicuticular compounds of Protopiophila litigata (Diptera: Piophilidae): identification and sexual selection across two years in the wild

Christopher Angell, Sharon Curtis, Anaïs Ryckenbusch, et al.

The epicuticular compounds (ECs) of insects serve both to waterproof the cuticle and, in many taxa, as pheromones that are important for various social interactions including mate choice within populations. However, ECs have not been individually identified in many species and most studies of their role in mate choice have been performed in a laboratory setting. Here we newly identify and [...]

Ecosystem services of a functionally diverse riparian zone in the Amazon–Cerrado agricultural frontier

The ecological services provided by protected riparian zones in human-altered landscapes are widely acknowledged, yet little is known about them. In this study, we assess ecosystem properties that a protected riparian zone maintains in contrast to environmental changes in its surroundings caused by agro-industrial activities in the northwestern fringe of the Brazilian Cerrado on the [...]

Steroid Receptors and Vertebrate Evolution

Michael Baker

Published: 2019-03-29
Subjects: Biochemistry, Biophysics, and Structural Biology, Biology, Ecology and Evolutionary Biology, Evolution, Life Sciences

Considering that life on earth evolved about 3.7 billion years ago, vertebrates are young, appearing in the fossil record during the Cambrian explosion about 542 to 515 million years ago. Results from sequence analyses of genomes from bacteria, yeast, plants, invertebrates and vertebrates indicate that receptors for adrenal steroids (aldosterone, cortisol), and sex steroids (estrogen, [...]
