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

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.

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

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

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.

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

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

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

The Five-second Rule Debunked

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

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

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

There’s a breast microbiome, and it’s different in women with breast cancer

In one of the most recent studies involving the microbiiome, researchers from the Mayo Clinic have identified significant differences in the breast bacteria of women with and without breast cancer.

The paper, published in the journal Scientific Reports, reveals that inside the breast is a com... 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...

Pseudomonas aeruginosa, casein hydrolysis, as noted by a zone of clearing around the organism, as... 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

A Sweater and a Shirt Came Before Just a Shirt

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

2016 MacArthur awards name two geomicrobiologists
