COLLEGE PARK, Md — Scientists at the University of Maryland and Tulane University have developed a computational model of a swimming fish that is the first to address the interaction of both internal and external forces on locomotion. The interdisciplinary research team simulated how the fish’s flexible body bends, depending on both the forces from the fluid moving around it as well as the muscles inside. Understanding these interactions, even in fish, will help design medical prosthetics for humans that work with the body’s natural mechanics, rather than against them. This research is published in the October 18, 2010 online early edition of the Proceedings of the National Academy of Sciences. (more…)

Deep Plumes of Oil Could Cause Dead Zones in the Gulf

WASHINGTON — A new simulation of oil and methane leaked into the Gulf of Mexico suggests that deep hypoxic zones or “dead zones” could form near the source of the pollution.

The research investigates five scenarios of oil and methane plumes at different depths and incorporates an estimated rate of flow from the Deepwater Horizon spill, which released oil and methane gas into the Gulf from April to mid July of this year.
