Developing new fluorescent metal sensors to explore the gastrointestinal tract

A University of Houston researcher is developing a new set of metal sensors that will be able to function in the gastrointestinal tract, a low oxygen environment, to examine how gut bacteria respond when trace metal nutrients, like iron and zinc, are thrown out of balance either through diet or disease.

Bacteria-driven process greatly decreases the toxicity of dioxin in the Passaic River

Bacteria that can help defuse highly toxic dioxin in sediments in the Passaic River - a Superfund hazardous waste site - could eventually aid cleanup efforts at other dioxin-contaminated sites around the world, according to Rutgers scientists.

Greater gut microbial diversity in kidney cancer patients linked to better treatment outcomes

Physicians at City of Hope, working in collaboration with scientists at Translational Genomics Research Institute (TGen), have found that greater gut microbial diversity in patients with metastatic kidney cancer is associated with better treatment outcomes on Food and Drug Administration-approved immunotherapy regimens.

Novel molecular survival strategy of Shigella bacterium uncovered

Enteric pathogens, such as the bacterium Shigella, can cause severe intestinal disease with bloody diarrhea. In a new study, researchers from Tokyo Medical and Dental University (TMDU) discovered a novel molecular survival strategy by which Shigella is able to cause damage to the intestines despite two elaborate protective mechanisms used by host cells.

Researchers study how bacteria adapt to their host cells

In the environment, they are often found inside unicellular organisms. A research team led by Matthias Horn at the Centre for Microbiology and Environmental Systems Science at the University of Vienna has made use of laboratory experiments to gain a better understanding of how these bacteria adapt to their host cell over time.

Researchers discover the exit route for Vibrio bacteria from cells

As soon as the foodborne pathogen Vibrio parahaemolyticus infects a human intestinal cell, the bacteria are already planning their escape. After all, once it is in and multiplies, the bacterium must find a way out to infect new cells.

Ultra-low voltage electricity effectively damages and kills bacteria

Ultra-low voltage electricity is effective at killing bacteria because it causes membranes that surround bacteria to leak, according to a new study by University of Arkansas researchers. The research advances work to fight drug-resistant bacteria.

"Ocean-in-a-lab" shows air pollution can alter weather patterns

Oceans cover almost three-quarters of the globe, yet little is known about how gases and aerosols made by ocean microbes affect weather and climate, or how human-produced pollution could influence this process.

Flavonoids in sorghum roots may lead to development of frost-resistant crop

Flavonoid compounds -- produced by the roots of some sorghum plants -- positively affect soil microorganisms, according to Penn State researchers, who suggest the discovery is an early step in developing a frost-resistant line of the valuable crop for North American farmers.
