Aging is an elusive property of life, and many important questions about aging depend on its definition. This article proposes to draw a definition from th
In essence, the ecosystem definition in biology is that it acts as the fundamental unit of nature. (Ref. 2) Just as a living organism is made up of cells that act as the structural and functional units of life, nature also consists of fundamental units calledecosystems. What is a simple ...

As scientists come closer to creating artificial life, the very definition of life is ever more elusive. Science writer Regis (The Biology of Doom ) tackles this large issue and more in a book that never quite finds its focus. By selecting the same title as Nobel laureate Erwin Schrodinger'...
Thus, narrow definitions have become inappropriate or inaccurate, and a more encompassing definition is required in order to describe this complex cell biological programme. Fig. 2: Growth of the primary literature in EMT. The first experimental analysis of epithelial–mesenchymal transition (EMT) in...
The vague definition ofmolecular biologywas nicely illustrated by the explanation that was given by Francis Crick (1916–2004) of how he became a molecular biologist15: I myself was forced to call myself a molecular biologist because when inquiring clergymen asked me what I did, I got tired ...
Advances in metagenomics have enabled genome-centric identification of many previously uncultured species that represent the potential tree of life lineages [35]. To further classify the Methanomassiliicoccales within the order, we collected 208 corresponding genomes from globally available datasets and ...
A fundamental question in protein evolution is whether nature has exhaustively sampled nearly all possible protein folds throughout evolution, or whether a large fraction of the possible folds remains unexplored. To address this question, we defined a se
