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
Daniel Haeusser, an Assistant Professor in the Biology Department of Canisius College in Buffalo, New York, discusses the misconception of assuming that photosynthesis exists as single process of strict coupling between energy conversion and carbohydrate production. Read More
U.S. public health officials are bracing for a wave of babies with severe Zika-related birth defects. The latest official numbers suggest 808 pregnant women in the U.S. appear to have been infected with Zika. Yet doctors are also steeling themselves for the possibility of birth abnormalities in ...

A single season of intense melting buffeted Antarctica in 2001-2002. It yielded changes that ranged from speeding up microbial food webs to shifting penguin populations. A special section in the October issue of BioScience examines the impacts on two very different Antarctic ecosystems.

Cranial neural crest cells--which give rise to the bones and cartilage of the skull--are vulnerable to Zika virus, report Stanford University School of Medicine researchers September 29 in Cell Host & Microbe. The discovery, made by infecting in vitro cultures of human cells, offers a potential ... Read More
For the past several decades, farmers have been abandoning their plows in favor of a practice known as no-till agriculture. Today, about one-third of U.S. farmers are no longer tilling their fields, and still more are practicing conservation tillage—using equipment that only disturbs the soil to... Read More
Another folk medicine remedy bites the dust. Cranberry capsules didn't prevent or cure urinary infections in nursing home residents in a study challenging persistent unproven claims to the contrary.
The research adds to decades of conflicting evidence on whether cranberries in any form can pr... Read More
Florida announced a new Zika transmission zone on Thursday, saying that the virus had popped up in a mile-square patch of northern Miami and that five people had been infected.
The area, around the Little Haiti neighborhood, goes from NW 79th Street in the north to NW 63rd Street in the south... Read More
A specific strain of the fungus, Fusarium oxysporum, circulates in the water distribution systems of five French hospitals, in two widely separated cities. This microbe is potentially a life-threatening risk to immunocompromised patients. The research is published September 23, 2016 in Applied a... Read More
It is (almost boringly) obvious that cell-to-cell communication is vital in multicellular organisms. To function properly, all cells in a tissue have to know – and let their neighbors know – where exactly they are, which tasks they're performing right now, when it's time to differenti... Read More
Small regulatory RNA molecules are vital for salmonella and other bacteria potentially harmful to humans: This RNA type controls gene activity and allows bacteria to quickly adjust to changing conditions of living and stress as are typical during an infection, for example, when entering the bloo...

In a very interesting development, a latest study has debunked the belief that it was safe to eat food fallen on the floor if picked up within “five seconds”.
Professor Donald W Schaffner, a food microbiologist at Rutgers University in New Jersey, said a two-year study he led concluded that no ... Read More
That twice-yearly trip to the dentist could do more than keep teeth and gums healthy: It may decrease the risk of pneumonia by reducing bacteria in the mouth, suggests research being presented at IDWeek 2016™.
Bacteria that commonly cause pneumonia include streptococcus, haemophilus, staphylo... Read More
It is not unexpected that the contemplation of bacteria and archaea should focus so much on the nature and importance of their cell envelopes. Here, after all, is the interface between the cell's interior and the outside world. It is also what a host perceives early on when becoming infected.... Read More
The 2016 MacArthur awards have just been announced. Among the handful of scientists are two microbiologists, Dianne Newman and Victoria Orphan, both at Cal Tech and both geomicrobiologists. We rejoice. Both are extraordinary scientists with an unusually broad range of interests.

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
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
Halloween will soon be upon us, and we are once again surrounded by stories of supernatural occurrences, violent crimes, monsters, and ghouls (not to mention a few creepy clowns thrown in for good measure). But are these just stories? Are ghosts, witches, and zombies just figments of our imagina... Read More
