Pattern analysis of phylogenetic trees could reveal connections between evolution, ecology

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 but can also be constructed ...

A study analyzes the unexpected behavior of hydrogen flames

Hydrogen flames can propagate even with very little fuel, within surprisingly narrow gaps and can extend breaking up into fractal patterns. That is the unexpected physical behavior of this gas when it burns, which has been ...

Halting climate change means a world without fossil fuels—not merely curbing emissions

A new study by two University of Toronto researchers is proposing a different way to think about tackling climate change—one that shifts focus away from emissions reductions in favor of eliminating fossil fuel energy altogether.
