Max Planck scientists unravel key pathway in the nitrogen cycle The anaerobic oxidation of ammonia (anammox) is an important pathway in the nitrogen cycle that was only discovered in the 1980s. Currently, scientists estimate that about 50 percent of the nitrogen in the atmosphere is forged by this process. A group of specialized bacteria perform the anammox reaction, but so far scientists have been in the dark about how these bacteria could convert ammonia to nitrogen in the complete...

Will our next generation of space travel be powered by cat urine? Researchers from Radboud University Nijmegen in the Netherlands released a study which details the work of a particular bacterium that turns the smelly contents of your cat box (or any other type of urine) into space fuel, AFP is reporting. The results of the scientists´ work show that the bacterium anammox, first identified in the 1990´s, thrives in the absence of oxygen and transforms ammonium, the...

Max Planck researchers discover hydrogen-powered symbiotic bacteria in deep-sea hydrothermal vent mussels The search for new energy sources to power mankind's increasing needs is currently a topic of immense interest. Hydrogen-powered fuel cells are considered one of the most promising clean energy alternatives. While intensive research efforts have gone into developing ways to harness hydrogen energy to fuel our everyday lives, a natural example of a living hydrogen-powered 'fuel cell' has...

Many medical devices, ranging from artificial hip joints to dentures and catheters, can come with unwelcome guests "“ complex communities of microbial pathogens called biofilms that are resistant to the human immune system and antibiotics, thus proving a serious threat to human health. However, researchers may have a new way of looking at biofilms, thanks to a study conducted by University of Iowa biologist David Soll and his colleagues published in the Aug 2 issue of the online, open...

The Alkek Center for Metagenomics and Microbiome Research at Baylor College of Medicine, under the direction of Dr. Joseph Petrosino, builds on local expertise in the study of how the microbiota that colonize the human body (the microbiome) impact health and disease. The center is coordinating and leading research and development efforts in this area across the college, the Texas Medical Center and with collaborators from around the United States and abroad. Established in January of 2011,...

A revolutionary biodegradable pellet which slowly releases antibiotics into the middle ear could transform the lives of thousands of children who suffer from glue ear. Scientists at The University of Nottingham have developed the tiny controlled-release antibiotic pellet which can be implanted in the middle ear during surgery to fit grommets, or small ventilation tubes. Over a period of three weeks it will release effective quantities of antibiotics to target any infection which can, in up to...

Study could help researchers develop anti-bacterial surfaces Jacinta Conrad, an assistant professor of chemical and biomolecular engineering at the University of Houston, likens her research into how bacteria move to "tracking bright spots on a dark background." Using a digital camera affixed to a microscope, Conrad and her collaborators videotape hours of moving bacteria. They then analyze these tens of thousands of images to determine exactly how they cross surfaces before forming biofilms,...

Scientists use new imaging technique to reveal complex microbial interactions Even the merest of microbes must be able to talk, to be able to interact with its environment and with others to not just survive, but to thrive. This cellular chatter comes in the form of signaling molecules and exchanged metabolites (molecules involved in the process of metabolism or living) that can have effects far larger than the organism itself. Humans, for example, rely upon thousands of products derived from...
