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

submitted by: MicrobeWorld
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...

Utilization of Geological Techniques to Help Solve an Archaeological Puzzle: When Did People Arrive in North America? Eleanora (Norrie) Robbins Department of Geological Sciences San Diego State University Knut Fladmark hypothesized that as soon as boat technology was developed 40,000 years ago, people probably traveled the oceans. The 40,000-year-ago shoreline is now below 150-160 ft (50 m) of water and an unknown thickness of sediment. So evidence for boat transport by maritime...
