Over a number of years, epidemiological studies established several well-defined risk factors for cancer, including age, heredity, diet, tobacco use, chronic viral infections, and inflammation. Paradoxically, the success of these studies left little room for incorporation of any new factors or c... Read More
Researchers at the Georgia Institute of Technology and the Joint BioEnergy Institute have engineered a bacterium to synthesize pinene, a hydrocarbon produced by trees that could potentially replace high-energy fuels, such as JP-10, in missiles and other aerospace applications. With improvements ... 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...

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
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
Our bones are remarkable feats of engineering; strong and yet light, shot through with holes and yet able to bear incredible loads. This super-strong natural material is built as cells incorporate hard minerals like calcium into living tissue. Now, scientists at the Massachusetts Institute of Te... Read More
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
In the spring of each year I teach a virology course to undergraduates and masters students at Columbia University. I produce video recordings of all my lectures not only for students in the course, but for anyone else who is interested in learning about viruses.
You can find my virology lect... Read More
When antibiotics first started being used in the 1940's they were considered a "miracle drug". It seemed that bacterial infections would no longer be a problem for the world. However, recently, one gene is making it seem as though the end of antibiotics is at hand. This gene is New Delhi metallo... Read More
When you hear the word “resurrection”, what’s the first thing that comes to mind? Religious miracles? Zombie viruses? The end of the world?
Whatever your mental association, I’m willing to bet it’s not “an emerging scientific discipline." Well, it just so happens a growing community of microb... Read More
Hello TWiMsters! I recently discovered the trifecta that is the TWi series, and now I can’t get enough of your discussions of all things micro. For graduate students like myself, keeping up with the scientific literature can all too easi... Read More
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
Close up view of the edges of an unknown bacteria swabbed form the bottom of a shoe, possible Bacillus, on TSA exhibiting spreading and rhizoid growth. The pigment is opaque white-beige with a mucoid surface towards the center of the colony and a matte surface towards the edges. Note: transmit... Read More
On the first day of Micro class instructors have students do an environmental swab. This sample was subcultured from a student who did the bottom of their shoe. The organism, possible Bacillus sp., was tough to scrap off the agar so subculture was done by taking a small chunk of agar containi... Read More
An unknown airborne environmental isolate on Mueller-Hinton agar exhibiting a single circular colony. White hyphal growth on the outer edges of the mold colony, where spores have not yet developed, surrounding the red/pink grainy spore formation in the center of the colony. This sample grew at ...

An unknown airborne environmental isolate on Mueller-Hinton agar exhibiting a single circular colony. White hyphal growth on the outer edges of the mold colony, where spores have not yet developed, surrounding the green and yellow grainy spore formation in the center of the colony with exudate ...

Media is poured in bulk in our lab for classroom use. Although contamination is low we do see airborne contamination especially durning the rainy season. This is an unknown airborne environmental isolate on Mueller-Hinton agar exhibiting a single circular colony. White hyphal growth can be see... Read More
For the millions of people forced to rely on a plastic tube to eliminate their urine, developing an infection is nearly a 100 percent guarantee after just four weeks. But with the help of a little bubble-blowing, biomedical engineers hope to bring relief to urethras everywhere.
About half of ... Read More
The emergence of community-acquired infections, such as urinary tract infections (UTI), due to strains resistant to common antibiotics are on the rise, according to Rhode Island Hospital researchers. The study is published online in the journal Antimicrobial Resistance and Infection Control.
