Five years after implementing a national initiative to reduce methicillin-resistant Staphylococcus aureus (MRSA) rates in Veterans Affairs (VA) medical centers, MRSA cases have continued to decline, according to a study in the November issue of the American Journal of Infection Control, the offi...

A newly discovered fungus that feasts on the skin of amphibians is threatening to decimate a species of salamander in the Netherlands, according to new research.
Fire salamanders are one of the most recognizable salamander species in Europe, and are characterized by their distinct yellow- and... Read More
Halomonas are a hardy breed of bacteria. They can withstand heat, high salinity, low oxygen, utter darkness and pressures that would kill most other organisms. These traits enable these microbes to eke out a living in deep sandstone formations that also happen to be useful for hydrocarbon extrac... Read More
Scientists at Emory Vaccine Center have found a link between immunity induced by vaccination and an ancient way that cells adapt to scarcity, a link that could help researchers develop vaccines against challenging infections such as HIV or malaria.
Researchers studying immune responses to the... Read More
We’re driving on a dirt road and my interpreter, one of the friendliest guys I’ve ever met, is absorbed in a conversation with a health worker in our group. Cornfields and rice paddies paint the landscape chartreuse. Donkey carts and herds of goats swerve into the plants when we rumble past. The... Read More
To know how many proteins assemble together at the nanoscale is fundamental for understanding protein function. Sometimes, proteins must be in an "oligomeric" state to be functional, although "oligomerization" of certain proteins can also lead to diseases. The ability to determine protein stoich... Read More
Here I remember a person who a great deal of influence on my views about microbiology in the classroom, and the laboratory: the late Abigail Salyers. RIP, Abigail. Read More
Some time ago, we asked this Talmudic Question: Can you think of a place on Earth where there is free water but no microbes? (A sterile flask of nutrient broth in a lab, the insides of the body, or an IV bag in a hospital don't count.) Someone answered that perhaps deep in Antarctica there would... Read More
MY GLOBAL VIDEO CHALLENGE (HOW MY SCIENCE AFFECTS MY COMMUNITY.)
Sometimes I wonder why diseases like typhoid fever and malaria lingers in West Africa and antibiotic as well as anti-malaria usage rises to resistant levels, until I met this community during one of my outreach trips. It was unima... Read More
By tinkering with their chemical structures, researchers at the University of California, San Diego School of Medicine have essentially re-invented a class of popular antimicrobial drugs, restoring and in some cases, expanding or improving, their effectiveness against drug-resistant pathogens in...

Cornell researchers have discovered five new species of a group of bacteria called Listeria – including one named for Cornell – that provide new insights that could lead to better ways to detect soil bacteria in food. To date, of the 10 previously known species of Listeria, only two are pathogen... Read More
An international team of researchers including scientists from the University of York have discovered a ‘microbial Pompeii’ preserved on the teeth of skeletons around 1,000 years old.
The key to the discovery is the dental calculus (plaque) which preserves bacteria and microscopic particles o... Read More
The emergence of antimicrobial resistance, coupled with the availability of fewer antifungal agents with fungicidal actions, prompted this present study to characterize Candida species in our environment and determine the effectiveness of virgin coconut oil as an antifungal agent on these specie...

In April three biohackers from a California Do-It-Yourself biology lab, BioCurious, posted a Kickstarter campaign to crowdsource their plan to bioengineer a glowing plant. They asked for $65,000. But by the close of their campaign at midnight on Thursday, June 6, they had raised a remarkable $48... Read More
A study conducted at the University of Strathclyde investigating the presence of Legionella in compost, has found that the bacteria exist in a significant number of commercial products.
The research, the first substantial analysis of Legionella in UK composts, suggests that the bacteria are a... Read More
Middle Eastern respiratory syndrome coronavirus (MERS-CoV), first identified in the fall of 2012 in a Saudi Arabian patient, has since infected over 160 individuals, causing 71 deaths. Identifying the source of infection is important for efforts to prevent further infections. Recently two studie... Read More
Every year, half of all Americans take some kind of pill as insurance against their diets.
But recently, researchers have noticed a surprising trend: Use of some of the most popular supplements is waning, possibly because of recent reports questioning their benefits and raising awareness abou... Read More
Many experts believe that chronic fatigue syndrome (CFS) has several root causes including some viruses. Now, lead scientists Shara Pantry, Maria Medveczky and Peter Medveczky of the University of South Florida’s Morsani College of Medicine, along with the help of several collaborating scientist...
