The opening ceremony for the Summer Olympics 2016 will be held this Friday, marking the onset of two weeks of competition between the world’s best athletes. The world has been focused on Brazil and its preparedness – not only for the infrastructure required for the games, but also for any potent... Read More
Michael Diamond visits the TWiV studio to talk about chikungunya virus and his laboratory's work on a mouse model of Zika virus, including the recent finding of testicular damage caused by viral replication.

If there is a problem built for a systems-based research approach, climate change – with its complex carbon and nitrogen cycles, numerous species involvement, and interaction of geographical zones – would be an excellent candidate. Concurrent with the launch of the systems-based microbial resear... Read More
Bacteria acquire and spread genetic information through several means. Some bacteria form a long, thin tube called a pilus, mediating transfer of DNA by direct cell-to-cell contact, in a process known as conjugation. Some bacterial take up environmental DNA and incorporate it into their existing... Read More
Evolutionary theory predicts that pairs of chromosomes within asexual organisms will evolve independently of each other and become increasingly different over time in a phenomenon called the 'Meselson effect.' Researchers from the University of Glasgow have demonstrated the Meselson effect for t... Read More
The study researchers found that placing a small, detoxified amount of E. coli in the guts of mice led to an increase in levels of leptin - known as the "satiety hormone."
Within 7 days of the increase, the number of sweet taste receptors on the rodents' tongues reduced, diminishing their ap... Read More
Marine plastic debris is a growing concern that has captured the general public’s attention. While the negative impacts of plastic debris on oceanic macrobiota, including mammals and birds, are well documented, little is known about its influence on smaller marine residents, including microbes t...

Evidence-based medicine is the approach used by doctors to make rational clinical decisions based on rigorous, well-controlled studies. By minimizing hunches, gut feelings, and anecdotal evidence, physicians and patients can follow recommendations that are most likely to have a positive outcome.... Read More
The Gram-positive bacterium Enterococcus faecium is a member of the ESKAPE pathogens for which drug resistance has been a growing problem. How E. faecium becomes drug resistant has been a long-standing question, and is the focus of a new study now available in Antimicrobial Agents and Chemothera... Read More
“Stefano, you seem like a smart person. Can I ask you why you decided to take a job with a scientific society?” I had just helped myself to a slice of a very sharp Stilton cheese, after a wonderful dinner supported by wonderful wine. All of a sudden the Stilton seemed even sharper. The question ... Read More
Pneumonia remains a serious worldwide problem, especially among the young, elderly, and immunocompromised. Over 900,000 children die each year due to the disease, and respiratory syncytial virus (RSV) is the most common viral cause (Streptococcus pneumoniae and Haemophilus influenzae type b bein...

Colony collapse disorder (CCD) has caused such a profound drop in honeybee populations that even the U.S. Congress is addressing the issue: Senator Jeff Merkley (D-Oregon) has proposed the Pollinator Recovery Act to preserve pollinator habitat. The rapid decline in these important pollinators af... Read More
Feeling under the weather? Are you congested, maybe having a hard time breathing, especially at night? Don’t worry – this is your body’s natural response to an infection. Mucus production is generally regarded as antimicrobial – it traps particles like virions before they can infect nearby host ... Read More
Given that the holidays are right around the corner, many of us will be trying to eat healthy outside of celebratory meals, and that includes turning to salad as a healthy meal option. Salads do provide fresh nutrients, but new research in Applied and Environmental Microbiology suggests pre-cut ... Read More
Tomorrow begins a Special President’s Edition ASM Conference, hosted by the American Society for Microbiology in collaboration with the American Society for Virology. The conference, “What Does the Biology of Flaviviruses Tell Us About Zika: The Importance of Fundamental Virus Biology” highlight... Read More
ASM aims to promote and advance the microbial sciences in a myriad of ways. In addition to promoting scientific education and discoveries, we also hope to engage the public with the diverse world of microbes! Last year, we held our first Agar Art contest, to highlight the often-overlooked beauty... Read More
I enjoy having my microbiology students explore their creativity in interesting ways. One approach is to have my micronauts "paint" on Petri dishes using luminous bacteria. In the past, I have inviting people to "vote" on their favorites, and hand out microbiologically themed gifts. This has ... Read More
In 2015, an unexpectedly large outbreak of Middle East Respiratory Syndrome coronavirus (MERS-CoV) in South Korea had a disastrous impact on the whole country and highlighted scientists limited knowledge of this virus. Now, new research into this outbreak has revealed some very surprising findin... Read More
As part of its Microbiology of the Built Environment initiative, the Alfred P. Sloan Foundation started funding projects a few years ago that touched on the interaction of microbiology with architecture, buildings or, in the case of Curtis Huttenhower, PhD, an associate professor of computationa...
