A new study shows that when enough bacteria get together in one place, they can make a collective decision to grow an appendage and swim away. This type of behavior has been seen for the first time in marine sponges, and could lead to an understanding of how to break up harmful bacterial biofilms, such as plaque on teeth or those found on internal medical devices like artificial heart valves.
"Stop acting like we're bulletproof" urged Congressman Elijah Cummings at the kick off of a two-day conference on the Chesapeake Bay and human health at the Institute for Marine and Environmental Science at Baltimore's Inner Harbor, May 14-15.
Solomons, Md. (August 31, 2011) – According to recent research, published in the journal Marine Ecology Progress Series (Vol. 436), the oyster population in the upper Chesapeake Bay has been estimated to be 0.3% of population levels of early 1800s due to overfishing, disease, and habitat loss.
Chesapeake Oyster Population Less Than One Percent of Historic Levels
A research effort designed to prevent the introduction of viruses to blue crabs in a research hatchery could end up helping Chesapeake Bay watermen improve their bottom line by reducing the number of soft shell crabs perishing before reaching the market. The findings, published in the journal Diseases of Aquatic Organisms, shows that the transmission of a crab-specific virus in diseased and dying crabs likely occurs after the pre-molt (or ‘peeler’) crabs are removed from the wild and placed in soft-shell production facilities.

Based on a comprehensive analysis of the latest scientific findings and new data, UMCES researchers Dr. Margaret Palmer and Dr. Keith Eshleman are leading a group of leading environmental scientists calling on the U.S. Environmental Protection Agency and the U.S Army Corps of Engineers to stay all new mountaintop mining permits.

The Gulf Research Program of the National Academies of Sciences, Engineering, and Medicine announced today the recipients of nine data synthesis grants, totaling more than $4.4 million, including a $504,000 grant awarded to the University of Maryland Center for Environmental Science’s Horn Point Laboratory to improve understanding of the responses of zooplankton and fish to stressors such as oil spills and low oxygen in the northern Gulf of Mexico.
Emissions controls on coal-fired power plants are making a difference in reducing exposure of mercury to people, especially in the western Maryland community. A study of air quality from the University of Maryland Center for Environmental Science found that levels of mercury in the air from power plant emissions dropped more than half over a 10-year period, coinciding with stricter pollution controls.
