Sources of Fecal Indicator Bacteria in Urban Streams and Ocean Beaches, Santa Barbara, California; Fecal indicator bacteria (FIB) concentrations in urban streams and ocean beaches in Santa Barbara, Calif. can exceed water-quality standards for recreational water. During low flow, high FIB concentrations in urban streams were associated with point discharges from storm drains, and concentrations in urban streamflow varied three-fold over the course of a day as a result of small variations in...

Our First Sip of Seawater

submitted by: ucsandiego

There's one way Scripps Institution of Oceanography at UC San Diego researchers see the future of desalination in California going. Before a regulatory structure can take shape to govern how seawater is treated and transported to a thirsty public, a gubernatorial order will be handed down that fast-tracks the construction of desalination plants during an episode of extreme drought when battles over water turn violent. Ecological casualties would be assured.

Stromatolites: Myths and Legends; Stromatolites are classically interpreted as “organo-sedimentary structures”, where layers and doming/branching result from microbial mats. As such, they could be considered quintessential ‘astrobiologic’ structures—a stromatolite, as a macroscopic manifestation of microbial processes, would be much easier to image remotely (on Mars, for example) than a microbe. While there is no doubt that some (perhaps most) stromatolites on Earth were formed...

Antibiotics: Is a Strong Offense the Best Defense? (Part 2 of 3) MWV

On September 18, 2008 at the Koshland Science Museum in Washington, D.C., Dr. Stuart Levy, professor of Molecular Biology and Microbiology at Tufts University School of Medicine and Dr. Linda Tollefson, Assistant Commissioner for Science at the U.S. Food and Drug Administration, discussed how to optimize antibiotic use and how to minimize the emergence of drug resistant pathogens. In part 2 of this 3 part video series, Dr. Levy discusses how antibiotic resistance develops, the development...

Antibiotics: Is a Strong Offense the Best Defense? (Part 1 of 3) MWV

submitted by: MicrobeWorld
Will we become defenseless against bacteria? Will bacteria always find a way to infect and even kill us? The emergence of antibiotic resistant strains of bacteria poses an enormous problem around the world. Scientists believe that the overuse of antibiotics is increasing the appearance of these pathogens. In the US, increasing casualties resulting from drug resistant staphylococcus infections received wide media attention. While antibiotics only work on bacterial infections, many patients...
