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
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
A virus that invaded the genomes of humanity's ancestors millions of years ago now plays a critical role in the embryonic stem cells from which all cells in the human body derive, new research shows.
The discovery sheds light on the role viruses play in human evolution and could help scientis... Read More
Given the evolutionary ability of microbes to rapidly adapt, the threat of antimicrobial resistance likely will never be eliminated. Today, many factors compound the problem, including the inappropriate use of antibiotics and a dwindling supply of new medicines, leading to a global crisis of ant... Read More
A study published recently in PLOS ONE authored by Dr. Henry Sun and his postdoctoral student Dr. Gaosen Zhang of Nevada based research institute DRI provides new evidence that Earth bacteria can do something that is quite unusual. Despite the fact that these bacteria are made of left-handed (L)... Read More
Six new cases of Heartland virus disease have been identified in residents of Missouri and Tennessee. The cause of this disease appears to be a member of the Phlebovirus genus in the Bunyaviridae family that was first identified in 2009 and appears to be transmitted by the Lone Star tick (Amblyo...

On any given day, one in 25 hospitalized patients - 4 percent - is battling an infection picked up in a hospital or other healthcare facility, according to a new survey by the Centers for Disease Control and Prevention (CDC).
That translates to more than 600,000 hospital patients each year. R... Read More
Q. When you eat yogurt or take a probiotic supplement, why aren’t the probiotic bacteria killed by stomach acids?
A. The point of consuming a probiotic supplement in a food like yogurt, a powder or a capsule is to introduce beneficial bacteria in the gut, said Dr. Christine Frissora, a gastro... Read More
Resistance to an entire class of antibiotics – aminoglycosides -- has the potential to spread to many types of bacteria, according to new biochemistry research. A mobile gene called NpmA was discovered in E. coli bacteria several years ago. Global spread of NpmA and related antibiotic resistance... Read More
A new kind of single-dose vaccine that comes in a nasal spray and doesn't require refrigeration could dramatically alter the public health landscape - get more people vaccinated around the world and address the looming threats of emerging and re-emerging diseases. Researchers presented the lates... Read More
GUECKEDOU, Guinea, April 8 (Thomson Reuters Foundation) - H iccups, say doctors in this remote corner of Guinea, are the final tell-tale sign of infection by the Ebola virus that has killed more than 100 people since an outbreak began this year.
Then come profuse bleeding, circulatory shock a... Read More
Researchers at Oregon State University have discovered novel proteins in, or on the surface of the bacteria that causes gonorrhea, which offer a promising new avenue of attack against a venereal disease that is showing increased resistance to the antibiotics used to treat it.
Only a single, t... Read More
There’s a hidden war going on for your fruit. The apple snatchers and orange thieves aren’t what you might think, though. Humans and other fruit-loving species are locked in an ongoing evolutionary battle against the microbes that also want to feast. Now, researchers believe they have found out ... Read More
Researchers with the U.S. Department of Energy (DOE)’s Joint BioEnergy Institute (JBEI), a multi-institutional partnership led by Berkeley Lab, have identified the genetic origins of a microbial resistance to ionic liquids and successfully introduced this resistance into a strain of E. coli bact...

On a recent morning, Noah Fierer, a professor of ecology and evolutionary biology at the University of Colorado, Boulder, found himself standing 1,000 feet above the farmland of eastern Colorado. He was perched near the pinnacle of the Boulder Atmospheric Observatory, a cellphone-tower-like spir... Read More
JOHANNESBURG, 2 April 2014 (IRIN) - Outbreaks of a deadly fungal disease in wheat crops in Germany and Ethiopia in 2013 have had the scientific community buzzing over the threat posed to global food security. Wheat stem rust, also known as wheat black rust, is often referred to as the “polio of... Read More
Bad weather and a delayed flight might be a recipe for misery - but in one instance 50 years ago it led to a discovery that has saved countless thousands of lives.
The discovery of the Epstein Barr virus - named after British doctor Anthony Epstein - resulted from his specialist knowledge of ... Read More
The American Academy of Microbiology has just released a new report, "Microbe-Powered Jobs: How Microbiologists Can Help Build the Bioeconomy," and along with it, an infographic, that summarizes the main points of the report.

In the otherwise barren space 220 miles above Earth's surface, a capsule of life-sustaining oxygen and water orbits at 17,000 miles per hour. You might know this capsule as the International Space Station (ISS), currently home to six humans—and untold billions of bacteria. Microbes have always f... Read More
An international research group led by Arizona State University professor Qiang "Shawn" Chen has developed a new generation of potentially safer and more cost-effective therapeutics against West Nile virus, and other pathogens. The therapeutics, known as monoclonal antibodies (MAbs) and their de... Read More
