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.

First, the scientists tagg... Read More

Frederick C. Neidhardt (1931 − 2016) An Obituary

A towering figure in microbiology, our friend Fred Neidhardt died on October 7, 2016 at his re­tire­ment home, the Academy Village near Tucson AZ. He made fundamental and abiding con­tri­bu­tions to research, teaching, academic administration, and social issues. In each, he left deep-root­ed mar... Read More

Bacteria on Device Said to Infect at Least 12 Patients in Pennsylvania

A device used during open-heart surgery that infected at least 12 patients at a Pennsylvania hospital last year was probably tainted at the plant in Germany where it was made, a federal investigation has found.

The device, called a heater-cooler machine, uses water to regulate the temperature... Read More

Happy couple

Happy bacteria couple drawn on TSA plate using a MRSA culture.
This picture illustrates how happy bacteria can become when people don't take all the antibiotic treatment correctly. Antibiotic resistance is a big problem nowadays. Read More

Oxidase Test

The oxidase test is performed using a reducing agent to detect bacteria’s ability to produce cytochrome c oxidase, an enzyme in the electron transport chain. The reducing agent (N,N,N′,N′-tetramethyl-p-phenylenediamine (TMPD)) changes or produces a purple color as it become oxidized. Pseudom... Read More

Cyanophages: Maximizing the Photo– and Redirecting the –Synthesis

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

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

Generation Zika

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 ...

Antarctica is practically defined by ice: What happens when it melts?

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.

Catalse Test on S. aureus

Organisms that have the catalase enzyme can detoxify the cell of hydrogen peroxide by converting it to oxygen gas. Bubbles indicate oxygen gas production after the addition of hydrogen peroxide directly to colonies growing on the TSA plate.

Zika infects neural cells related to skull formation, affecting their function

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

Examining Aspergillus fumagatus on the Space Station

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

Soil microbes flourish with reduced tillage

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

A New Zika Zone in Miami, but No Reason to Panic, Scientists Say

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

Post-Ebola Recovery in Sierra Leone

This first video focuses on the efforts needed to rebuild these service... Read More

Potentially life-threatening fungus found in water distribution systems of five French hospitals

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

Quorum Sensing for the Mutes

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...

Bacteria: Third RNA binding protein identified

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...

Cranberries squashed as folk remedy for urinary infections

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
