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
Microbes are hardly the poster-children of climate change, but they have far more impact than polar bears on Earth’s carbon cycle – and therefore on our climate. A new study published Friday in Science Advances finds that seabed bacteria and archaea (which look like bacteria but have very differ... Read More
Three young inventors and students at Stanford University are working to develop proteins that fight antibiotic resistant bacteria. They are optimistic they have found something that works. The proteins the team is developing attack "something that's essential to bacterial survival". But they wo... 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
The Fellowship of the Virus trace the early history of HIV in North America, based on genome sequences obtained from late 1970s archival sera, which also reveal that Gaetan Dugas was not Patient Zero.

I had my #Bio350 micronauts write one page "Nanobiographies" of their #MicrobialTermPapers. I'm very pleased. Read More
The call for abstracts is now open for Microbe 2017, the premier microbiology conference hosted by the American Society for Microbiology. This is your opportunity to submit your important research in the microbial sciences to the largest scientific audience, with a 50% higher chance of presentin... Read More
Just as humans have a complex relationship with microorganisms, some make us sick while others aid our health, plants too coexist with a mixture of mostly helpful but sometimes harmful microbes.
While geosmin may overwhelm our noses, plants are able to detect a number of compounds produced b... Read More
Most of the research to understand the effects of Zika infections has focused on pregnant women and birth defects. But new study in mice that focuses on the male reproductive system raises serious concerns about its effects on men.
Three weeks after male mice were infected with Zika, their te... Read More
The TWiVsters explain how superspreader bacteriophages release intact DNA from infected cells, and the role of astrocytes in protecting the cerebellum from virus infection.
Investigators at Johns Hopkins report they have new evidence that a bacterium known to cause chronic inflammatory gum infections also triggers the inflammatory “autoimmune” response characteristic of chronic, joint-destroying rheumatoid arthritis (RA). The new findings have important implication... Read More
Aravinda de Silva, PhD, professor of microbiology and immunology, and Stefan Metz, PhD, a post-doc in de Silva's lab, make up one of only two U.S. teams to be named to the European Union-funded worldwide initiative. Sponsored by the European Union's Horizon 2020 Programme, the consortium is inve... Read More
A new cross-sectional study comparing the asthma and environmental profiles of children aged 7-14 years, from Amish households in Indiana, and Hutterite households in South Dakota found that:
1. Dust extracts from Amish households were found to have higher concentrations of endotoxins and alle... Read More
Vincent, Michael, and Michele explain the use of an electrochemical gradient to eliminate bacterial biofilms, and how phage susceptibility can be transferred by exchange of receptor proteins.
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
A benefit of the voluminous wealth of research produced is that it allows us to stand on the shoulders of giants – we can take advantage of established facts, tools, and datasets. This may mean using a mutant library to find genes in your organism that are important for the process you study; ac... Read More
In some individuals, an influenza A virus infection can cause asymptomatic Staphylococcus aureus (S. aureus) to travel to the lungs where it can trigger severe, sometimes deadly, secondary pneumonia. S. aureus is one of the most common causes of secondary bacterial pneumonia in cases of seasonal... Read More
At St. Jude Children’s Research Hospital in Memphis, Tenn., scientist Stacey Schultz-Cherry has been studying the impact of obesity on influenza severity.
“We saw during the 2009 flu pandemic that there’s an epidemiological link between people getting severe flu and being obese,” says Schultz... Read More
Whether you're in town for ASM Microbe 2016 and looking for something to do with friends or family, or you're local to the Boston-area, come out to our "Microbial Conversations" public science event at the MIT Museum! Join us for short, sharp conversations about a variety of topics in microbiolo... Read More
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
