Where Zika Struck Hardest, Brazil Moms Say More Help Needed

Zika initially was known only to cause flu-like symptoms in some people. But a surge late last year in cases of babies born with small heads in northeast Brazil set off worldwide alarm about the virus, which was later linked to a birth defect known as microcephaly. When the connection was made, ... Read More

Zika Virus Found in Woman's Vagina for Weeks

A woman infected with Zika carried the virus in her vagina for weeks, researchers reported Tuesday.

It's yet more evidence that the virus can hang out in the human body for weeks or months after symptoms have cleared up. The findings, rushed online by the journal Emerging Infectious Diseases,... Read More

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

Physarum

Physarum polycephalum, slime mold, grown in a large perti plate on moist paper towels using oatmeal as the food source. Culture was grown in the dark at room temperature. The paper towel was moistened every day with tap water. After 3 week’s the culture formed sporangia (fruiting bodies). Image ... 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.

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

Post-Ebola Recovery in Sierra Leone

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

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.

Carbon-Based (micro) Life

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

Breaking a bacterial-made magnet apart

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...

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
