In biology, phylogenetic trees represent the evolutionary history and diversification of species—the "family tree" of Life. Phylogenetic trees not only describe the evolution of a group of organisms ...

While teaching a class on coarse-graining methods in physics, James O'Dwyer realized that the technique could be used to understand how microbes evolve over time. The results, published in PNAS, ...

Once you look at trees through the eyes of a dendrochronologist, you never quite see the leafy wonders the same way again. Peel away the hard, rough bark and there is a living document, history ...

Leonardo da Vinci’s sketch of a tree illustrates the principle that combined thickness is preserved at different stages of ramification. The math that describes the branching pattern of trees in ...

Researchers used more than 1,400 climate-sensitive tree-ring chronologies from multiple tree species across North America to reconstruct the Palmer drought severity index (PDSI), a widely used soil ...
