Why doesn’t a single species that is better at competing for the resource crowd out all the others? According to new findings by Macquarie University, the answer to this question on coral reefs is like a very big game of rock-paper-scissors.

The 64-million-atom simulation offers new insights into how the virus senses its environment and completes its infective cycle.
