Close Quarters: The Importance of Interspecies Interactions in Microbial Biofilms

Biofilms, surface-attached microbial communities encased in an extracellular matrix, are one of the most common macroscopic microbial structures we can see in nature. Biofilms like those seen in pond scum, in dental plaque, or in hot springs, are mixed communities with the members forming both a... Read More

Scientists Uncover Why Hepatitis C Virus Vaccine Has Been Difficult to Make

Researchers have been trying for decades to develop a vaccine against the globally endemic hepatitis C virus (HCV). Now scientists at The Scripps Research Institute (TSRI) have discovered one reason why success has so far been elusive.

Using a sophisticated array of techniques for mapping tin... Read More

Microscopic technique to observe antibiotics live in action

A new microscopic technique is enabling scientists to observe the antibiotic daptomycine live in action. This marks an exciting first, because even though doctors have been prescribing this antibiotic for over a decade, its precise mechanisms have remained unclear.

Microbe hunters discover long-sought-after iron-munching microbe

A microbe that ‘eats’ both methane and iron: microbiologists have long suspected its existence, but were not able to find it - until now. Researchers at Radboud University and the Max Planck Institute for Marine Microbiology in Bremen discovered a microorganism that couples the reduction of iron... Read More

Microbe Mafia

Meet the Microbe Mafia: K. rhizophila, E. coli, and C. xerosis. They might seem like friendly bacteria but are always looking for opportunities to cause disease. Well ..... K. rhiz is really not that bad but peer pressure works in bacterial populations as well. When armed with C. violaceum th... Read More

'Farming' bacteria to boost growth in the oceans

Chemosynthetic symbionts are bacteria living inside or on the surface of animals, supplying their host with food that would otherwise be unavailable. It has long been known that these bacteria fix carbon and convert it into organic forms. Microbiologist Jillian Petersen and colleagues from the U... Read More

MRSA uses decoys to evade a last-resort antibiotic

Methicillin-resistant Staphylococcus aureus (MRSA) is responsible for thousands of deaths around the world each year. However, because the bacteria are resistant to many different antibiotics, treatment options are limited, and often ineffective.
