Zika virus detected in ‘a few’ units of donor blood in Florida

Zika virus has been detected in units of donated blood in Florida, federal health officials said Tuesday.

But the number so far is small, and new testing in high-risk areas kept the virus from entering the U.S. blood supply.

Food and Drug Administration officials confirmed that “a few” uni... Read More

Microbes After Hours: The Necrobiome - Microbial Life After Death

What happens to us after we die?  A decomposing corpse becomes its own mini-ecosystem, hosting insects, scavengers and multitudes of microbes.  Microbes from the environment, the corpse, as well as the insects and scavengers are blended together and work to recycle tissues back to t... Read More

UC Davis researchers hope monkeys can aid Zika vaccine development

At first glance, the monkeys being studied by University of California, Davis researchers may look like they’re part of a zoo exhibit, but these primates may soon hold the key to preventing pregnant women from passing the Zika virus to their unborn babies.

Your next migraine might be thanks to your mouth microbes

When Antonio Gonzalez began doctoral studies in Rob Knight’s laboratory, then at University of Colorado, Boulder, the computer scientist quickly learned about microbes and their connection to human health. He soon found a connection to his wife’s health jumping out of the literature at him.

Migraine Sufferers Have Higher Levels of Nitrate-reducing Microbes in their Mouths

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

Seeking understanding of the bacterial sec system

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

A promising step toward controlling Zika virus and dengue fever

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

Dr House goes digital as IBM’s Watson diagnoses rare diseases

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

Viruses found to attack ocean archaea far more extensively than thought

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

Plankton blooms in New Zealand suggest the ocean is responding to climate change

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

Women don’t feel welcome in these STEM fields

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

Scientists uncover new facets of Zika-related birth defects

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

New research offers insights into managing agricultural runoff and coastal dead zones

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

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...

Experiment in monkeys raises hopes of "functional cure" for HIV

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

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

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

Quorum Sensing for the Mutes
