Every few months, chemist Brian Bachmann sheds his white lab coat, collects his flashlight, helmet, surgical gloves and knotted rope, puts on old clothes and hiking boots and heads to a nearby cave. Bachmann, an assistant professor of chemistry at Vanderbilt, has combined his industrial experience in natural… Read More

Cosmologist Paul Steinhardt (Photo courtesy of Paul Steinhardt) Today, the idea that the universe expanded dramatically for a period of time after its birth in the Big Bang is one of the cornerstones of modern cosmology. However, Paul Steinhardt, the Albert Einstein Professor of Science at Princeton University,… Read More

Vanderbilt physicist Robert Scherrer supplements his scientific research with writing science fiction stories. Bob Scherrer is bicultural: Not only is he a practicing theoretical physicist, but the chairman of Vanderbilt’s physics department is also a published author of science fiction. Several years ago we did a… Read More

Toadstools in early morning light (Photo by Guy Nicholls, iStock) For some reason, fungi don’t get no respect. Despite the fact that genetically they are more closely related to animals than to plants and despite the fact that they play an absolutely critical role in the environment,… Read More

Since the days of Darwin, the “tree of life” has been the preeminent metaphor for the process of evolution, reflecting the gradual branching and changing of individual species. The discovery that a large cluster of genes appears to have jumped directly from one species of fungus to another, however,… Read More
