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...

The human digestive system, a hotbed of living bacteria, comes in three variations just as distinct as variations in blood type, according to a study released on Wednesday. These "enterotypes" are found in people around the world and exist independent of race, origin, diet, body mass index (BMI), age and state of health, the study says. Researchers from the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, collaborators in the international MetaHIT consortium, and...

Gut type can explain efficiency of uptake of nutrients and medicines "The three gut types can explain why the uptake of medicines and nutrients varies from person to person," says bioinformatician Jeroen Raes of the VIB and Vrije Universiteit Brussel, one of the two lead researchers in the study. "This knowledge could form the basis of personalized therapies. Treatments and doses could be determined on the basis of the gut type of the patient." Improved knowledge of the gut types could also...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
