Some of nature's most fascinating phenomena -- from clouds forming to insects hovering to droplets of saliva filled with influenza viruses floating in the office environment-- represent different types of turbulent fluid flows. The field of fluid dynamics deals with these and many other types of flows and helps to inform fields as diverse as aerospace and industrial hygiene. Session L42 examines a number of these practical examples and details what the latest breakthroughs measuring and modeling them is telling us about their nature.
SPEAKERS: Bin Liu (New York University) will discuss the keys to free and stable hovering of asymetric bodies -- work that is shedding light on the flight of hovering insects. John McLaughlin (Clarkson University) will present the first direct numerical simulation of the air velocity field and particle trajectories in a room -- looking at how particles spread in an office environment. Yong Wang (University of California, Los Angeles) will describe the physics that leads to the "cauliflower" shape of fair weather clouds.

THE MECHANICS OF CELLS AND MOLECULAR MOTORS: A NEW CONTROVERSY (Session L6)
The "intracellular" soup of material inside living cells is one of the most complex fluids known to science -- an almost impossibly complicated mixture of proteins, salts, and fatty acids, and numerous other molecules that coexist, interact, and play fundamental roles determining the fate of the cell. The interactions between these cellular materials with the environment surrounding the cells may hold some of the keys to understanding fundamental biological phenomenon that can aid in drug discovery, disease prevention, and the treatment of terminally ill patients.
