Washington, DC – October 18, 2016 – Researchers at the University of California San Diego School of Medicine (UC San Diego) have found an association between migraines and microbes that reduce nitrates. Analyzing data from the American Gut Project, they found that migraine sufferers harbored sig... Read More
How do bacterial proteins destined for export move from inside to outside the cell? As mBiosphere readers may know, there are a number of secretion systems that bacteria use to move materials from inside the cell to outside the cell. Some of these systems, such as the Sec secretion system, are c... Read More
Five UCLA researchers were part of an international team that has used X-rays to reveal the structure of a molecule that is toxic to disease-carrying mosquitoes. The findings move the scientific world one step closer to genetically engineering a toxin that would be lethal to species that carry d... Read More
Medics charged with diagnosing the kind of extremely rare diseases that Hugh Laurie’s consultant routinely spots in TV drama House have found that artificial intelligence can do a similar job – but in seconds rather than days or weeks.
From December, doctors at the University Hospital of Marb... Read More
Advancing Partners & Communities is excited to launch part one of a two-part compelling, original video series showcasing the work in Sierra Leone to improve primary health care services at health posts and community levels. This first video focuses on the efforts needed to rebuild these service... Read More
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
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.
The bonded carbons are shown using E. coli, E. faecalis, and C. violaceum. Using BBL's CHROMagar, we were able to show the pi bonds in pink (E. coli) and blue (E. faecalis). Read More
Currently, it is well established that prokaryotes possess cytoskeleton and organelles. This image depicts how magnetic organelles, magnetosomes, are properly partitioned and segregated by a mechanism that relies on the treadmilling of a dedicated cytoskeletal structure, the actin-like MamK fila...

A team of researchers with members from Italy, Australia, the U.S. and Japan has found that viruses are the main culprit in killing archaea in the deep sea. In their paper published in the journal Science Advances, the researchers describe the techniques they used to study archaea in soil sample... Read More
The appearance of white blooms of plankton east of New Zealand suggests the ocean is responding to climate change, according to research by Victoria University of Wellington scientists.
As part of her Master's study, Bella Duncan investigated coccolithophores, a white algae with remains known... Read More
Researchers say there are 3 main factors that explain why women are more represented in some STEM (science, technology, engineering, and mathematics) fields than others.
The most powerful one, they say, is a “masculine culture” that makes many women feel like they don’t belong.
“There is w... Read More
In the new study, the scientists observed the virus's effects in animal models at two different points -- during early postnatal development, when the brain is growing rapidly, and at weaning, when the brain has largely reached adult size.
"In early postnatal Zika-infected models some brain a... Read More
A study published today in Ecology Letters adds to a growing body of work examining the relationship between harmful algal blooms in the Gulf of Mexico and agricultural runoff. The article focuses on water chemistry, specifically the ratio of dissolved silica to dissolved inorganic nitrogen in 1... 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...

A new drug combination helped stave off a monkey version of HIV for nearly two years after stopping all treatments, raising hopes for a functional cure for HIV, U.S. researchers said on Thursday.
The treatment involved standard HIV drugs, known as antiretroviral therapy or ART, plus an experi... Read More
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
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
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
