Many microorganisms produce secondary natural products, the potential antibioticeffects of which are extensively investigated. German scientists have now examined a class of quinone-like substancescontaining an additional epoxide functional group for their antibiotic activities. As they report i... Read More
Playing classic video games like Pac-Man with living single-celled microbes thinner than a human hair is now possible thanks to an interactive microscope developed by bioengineers at Stanford University.
After several prototypes, the researchers released blueprints earlier this month for a "L... Read More
As the durations of manned space missions increase, it is vitally important to understand the long-term consequences of microbial exposure on human health in closed human habitats. One mission of the Microbial Observatory Experiments on the International Space Station is to examine the traits an... Read More
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
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
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.
First, the scientists tagg... Read More
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
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
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
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.
But until now scientists didn't know how MRSA ... Read More
The world has been galvanized by the Zika epidemic spreading through the Americas, which has left more than two thousand infants with severe brain damage. But for pregnant women and their infants in the United States, cytomegalovirus, or CMV, is the far greater viral threat.
Every year, 20,00... Read More
The TWiVome reveal the first eukaryotic genes found in a bacteriophage of Wolbachia, and how DNA tumor virus oncogenes antagonize sensing of cytoplasmic DNA by the cell.
In Miami, where the Zika virus continues to be transmitted by mosquitoes, pregnant women are taking all sorts of measures to deal with the potential threat. Some barricade themselves inside, others leave town and a few, like Borr, take other precautions.
When she took the photo in September, ... Read More
The number of cases of Zika virus detected in Australia is now up to 76, with seven cases diagnosed this year in Far North Queensland.
The latest figures from the Federal Health Department show travellers arriving from countries such as Fiji, Tonga and Mexico have brought the virus to Austral... Read More

The bad news for people who suffer from migraines is that the debilitating headaches may be caused by some of your favorite foods.
Everyone who gets migraines can identify the symptoms: increased sensitivity to light and noise, blurred vision and dull throbbing in the head.
A new study by ... Read More
The remarkable transformation in the control of infectious diseases by antibiotics is one of the glorious stories in microbiology. But now, almost inseparable from their discovery and application, is its nasty sequel, the rapid evolution of antibiotic resistance. We continually read reports of... Read More
