Bacteria 'launch a shield' to resist attack Researchers from the University of Copenhagen and the Technical University of Denmark along with other collaborators in Denmark and the US found that the bacterium Pseudomonas aeruginosa can 'switch on' production of molecules that kill white blood cells - preventing the bacteria being eliminated by the body's immune system. view more (2009-11-02)
Building better bone replacements with bacteria Bacteria that manufacture hydroxyapatite (HA) could be used to make stronger, more durable bone implants. Professor Lynne Macaskie from the University of Birmingham this week (7-10 September) presented work to the Society for General Microbiology's meeting at Heriot-Watt University, Edinburgh. view more (2009-09-08)

Cool plasma packs heat against biofilms Though it looks like a tiny purple blowtorch, a pencil-sized plume of plasma on the tip of a small probe remains at room temperature as it swiftly dismantles tough bacterial colonies deep inside a human tooth. view more (2009-06-11)
Texas A&M researchers examine 'invading' bacteria in DNA Researchers at Texas A&M University's Artie McFerrin Department of Chemical Engineering have discovered how certain types of bacteria integrate the DNA that they have captured from invading enemies into their own genetic makeup to increase their chances of survival. view more (2009-06-03)
Are You Okay to Kiss? A quick breath check in the palm of your hand can never give accurate results. Whether you're about to lean in for a smooch or start a job interview, you're better off asking a trusted friend if your breath is sweet. But what if a friend isn't around when you need one? view more (2009-05-19)
hus the bile does not overflow A consequence of the different cancers of the hepatobiliary system is blocked bile ducts. However, artificial catheters known as "stents" can remediate this problem. view more (2009-05-11)
Microbes turn electricity directly to methane without hydrogen generation A tiny microbe can take electricity and directly convert carbon dioxide and water to methane, producing a portable energy source with a potentially neutral carbon footprint, according to a team of Penn State engineers. view more (2009-03-31)
Genes that make bacteria make up their minds Bacteria are single cell organisms with no nervous system or brain. So how do individual bacterial cells living as part of a complex community called a biofilm "decide" between different physiological processes (such as movement or producing the "glue" that forms the biofilm)? view more (2009-03-30)
Strategy Discovered for Fighting Persistent Bacterial Infections Researchers at National Jewish Health have discovered a promising strategy for destroying the molecular scaffolding that can make Pseudomonas bacterial infections extremely difficult to treat in cystic fibrosis patients, wearers of contact lenses, and burn victims. Jerry Nick, MD, Associate Professor of Medicine at National Jewish Health, and his... view more... (2009-03-24)
Syracuse University researchers build new surface material that resists biofilm growth; new technology may lead to development of improved medical implants This is the tale of two biological substances-cells from mammals and bacteria. It's a story about the havoc these microscopic entities can wreak on all manner of surfaces, from mighty ships to teeth and medical devices, and how two Syracuse University researchers are discovering new ways to prevent the damage. view more (2009-03-20)
No hiding place for infecting bacteria Scientists in Colorado have discovered a new approach to prevent bacterial infections from taking hold. Writing in the Journal of Medical Microbiology, Dr Quinn Parks and colleagues describe how they used enzymes against products of the body's own defence cells to prevent Pseudomonas aeruginosa bacteria from building a protective biofilm which... view more...

Biofilms: Even Stickier Than Suspected Biofilms are everywhere - in dental plaque and ear canals, on contact lenses and in water pipelines - and the bacteria that make them get more resilient with age, finds a new study in FEMS Microbiology Letters. view more (2009-03-13)
New method monitors critical bacteria in wastewater treatment Researchers have developed a new technique using sensors to constantly monitor the health of bacteria critical to wastewater treatment facilities and have verified a theory that copper is vital to the proper functioning of a key enzyme in the bacteria. view more (2009-02-05)
Single gene lets bacteria jump from host to host All life - plants, animals, people - depends on peaceful coexistence with a swarm of microbial life that performs vital services from helping to convert food to energy to protection from disease. view more (2009-02-02)
Small molecule triggers bacterial community While bacterial cells tend to be rather solitary individuals, they are also known to form intricately structured communities called biofilms. view more (2008-12-23)
