There is no end to the fascinating questions we can ask about how the natural world functions. From dissecting the molecular mechanisms at play in cells to understanding the complexity of interactions in the biosphere, the beauty and mystery of nature astounds. There has never been a more exciting time to study biology, with subjects ranging from climate change and the conservation of biodiversity to the origin and evolution of life, and from the form and function of organisms to the ongoing “omics” revolution at the molecular level. Regardless of your area of interest, there is something in biology for you -- questions waiting to be answered and riddles of nature to be solved.
