Scientific Discovery, Frame by Moving Frame The world is full of questions about the natural world that scientists are working to answer every day. Beginning this week, a new science video series will showcase some of the research that is revealing the answers to the natural world's many mysteries. In years past, research results were often relegated to the pages of scientific journals - written for other scientists and accessible to a select few. But the pervasiveness of digital photography and video is changing how science is done and how it is brought to the public. Now you can often see science happening before your eyes. High-speed video can capture the cheetah's turn, or the dragonfly's anticipation of a gnat trying to evade its fate. You can see waves of the bacteria Myxococcus xanthus, in the video above, spread across a prey sample in high-resolution, time-lapse photography. But what's missing is a guide. The science remains complex, the interactions between prey and predator subtle, the microscopic drama is sometimes very quietly dramatic. That's where I come in. In ScienceTake, a new regular series on the science pages, I will be your guide to discoveries, large and small - a kind of scientific sportscaster, giving you the science play-by-play. So join me in coming weeks. We will look into controlling the starfish's stomach. We will see why the peacock's dance is so elaborate. And we will take a ride on the fungal superhighway.
