• Deadly U.S. superbugs spread to South America: Variations of two deadly superbugs that had previously only been discovered in the United States have surfaced in South America. Variations of two U.S. strains of killer bacteria have cropped up in South America, researchers say. Variations of two U.S. strains of killer bacteria have cropped up in South America, researchers say. The drug-resistant microorganisms are sweeping across communities in Colombia and have the potential to unleash devastating results, according to researchers at The University of Texas Medical School at Houston.
• Biomedical Engineers' Detective Work Reveals Antibiotic Mechanism: A series of genetic clues led a team of Boston University biomedical engineers to uncover exactly how certain antibiotics kill bacteria. The findings could help rejuvenate the efficacy of older antibiotics and reveal new antibiotic targets within bacterial cells.

• Visual Science - How Termites Live on a Diet of Wood - NYTimes.com: "Wood is indeed convertible to useful chemicals, because termites do it every day, causing $1 billion of damage every year in the United States. But to live on a diet of wood is challenging, not least because wood contains so little nitrogen. So how do termites do it? [...] The trick lies in a cunning triple symbiosis, a team of Japanese scientists report in Friday?s issue of Science. In the termites? gut lives an amoeba-like microbe called a protist, and inside each protist live some 10,000 members of an obscure bacterium. [...] The overall process whereby this troika of species makes a meal of wood is shown in the graphic at left: the termite chews the wood into particles that are absorbed by the amoeba. The amoeba breaks down the cellulose of the wood and gets the nitrogen it needs from its bacteria. The net result is that the two microbes digest wood into sugars and other nutrients of use to the termite."

• First Detailed 3-D Glimpse Of Bacterial Cell-wall Architecture: The bacterial cell wall that is the target of potent antibiotics such as penicillin is actually made up of a thin single layer of carbohydrate chains, linked together by peptides, which wrap around the bacterium like a belt around a person, according to research conducted by scientists at the California Institute of Technology (Caltech). This first-ever glimpse of the cell-wall structure in three dimensions was made possible by new high-tech microscopy techniques that enabled the scientists to visualize these biological structures at nanometer scales.
