Genetic and biochemical analyses demonstrate that cell-surface lectin receptors can potentially function as extracellular NAD+-binding receptors and provide direct evidence for extracellular NAD+ being a bona fide endogenous signaling molecule in plants.
Key numbers about the biology of the SARS-CoV-2 virus and the infection of a single human host by the virus have been compiled from the peer-reviewed literature.
More than 30 published articles have suggested that a protein kinase called MELK is an attractive therapeutic target in human cancer, but three recent reports describe compelling evidence that it is not.
Dubbed the 'green yeast', the model alga C. reinhardtii has profoundly advanced many areas of biology, but much remains to be learnt about its life in the wild.
A better understanding of the remarkable diversity, natural history and complex ecology of E. coli in the wild could shed new light on its biology and role in disease, and further expand its many uses as a model organism.
To leverage the tools, resources and knowledge that exist for C. elegans so that we can study ecology, evolution and other aspects of biology, we need to understand the natural history of this important model organism.
A late Middle Pleistocene age for Homo naledi demonstrates a diversity of hominin species in Africa at this critical time in the archaeological record.
