Re-reading the Classics

Written by
Important tools used in synthetic biology, bio-therapeutic design, and popular events like International Genetically Engineered Machine (iGEM) Competition emerged decades ago through basic questions about the nature of gene expression.  A single 1961 paper by Nobel Laureates François Jacob and Jacques Monod laid the groundwork upon which researchers continue to build. As work slows this time of year, it's a great time to visit this classic research.

Each year, millions across the globe travel for the holidays. But with the increase in human travel, what microbial gifts are we bringing home with us?
When you gain weight, you gain changes in microbes and metabolism too. But they’re harder to get rid of than those last five pounds ever were.

No Democracy for Tardigrades

Are you worried about the presidential election? Here's one way of putting it all in perspective—look into the beauty and biodiversity of the microbial world.
All cellular microbes thus far investigated release vesicles to their extracellular environment. These formations remain incompletely understood and are in many ways mysterious, but a recent flurry of research focused on gram-negative vesicles has shed a bit of light on their function and formation.

The Nose Knows Beneficial Bacteria

Complex bacterial communities live within our nasal passages. But what are these nasal bacteria actually doing? One step towards addressing this question is to mine bacterial community composition surveys for clues as to which bacteria might be interacting with each other or which bacteria are associated with disease. Hypotheses formulated from these datasets can then be tested in the laboratory.
What’s your gut feeling on microbiome research?  It seems like nearly every day a new connection between the human gut microbiome and a feature of our health is learned. While the advancements are exciting we need to balance enthusiasm with patience to avoid the spread of misconceptions.

After Hurricane Matthew, Cholera Becomes a Concern

Written by
Hurricane Matthew hit Haiti on October 4, 2016, and the southeast United States two days later, leaving tens of thousands without power, transportation, and in the worst cases, homes. Because of its extreme poverty, and its continuing recovery from previous natural disasters, Haiti is looking at a potential uptick in what had been a slight decline in its cholera epidemic. What is cholera and how might the aftermath of Hurricane Matthew affect the spread of its disease? Read below for a brief overview and more resources from ASM:
Research on the human microbiome has captured the public imagination. Data showing that gut bacteria could be involved in protection against everything from malnutrition to obesity to anxiety and sleep disorders has led to the hope that perhaps the answers to what ails us have literally been inside us all along. With this hope, however, have come calls for caution and moderation from a number of researchers.
The Nobel Prize for Medicine this year went to Dr. Yoshinori Ohsumi of the Tokyo Institute for Technology for his work on autophagy, the process of digesting unneeded or damaged cellular components. This process plays a role in many central cellular activities, with applications ranging from genetic to infectious diseases in microbes, plants, and animals. Dr. Ohsumi’s work to uncover the genes required for autophagy has relied on many model organisms, including the model microbe Saccharomyces cerevisiae. His work was published broadly, including in journals published by ASM. Some of these publications uncovered novel mechanisms or interactions. We spoke with…

Food for Thought: Microbes and Fermented Food

Written by
We might not always think about them when we sit down to eat a meal, but microbes are responsible for many of our favorite foods.  Are you ready to try some homemade microbiology?    
It appears that an imbalance of microbes in the GI tract can adversely affect how the immune system functions. In fact, we are learning more and more how normal human development is dependent on the microbes that have coevolved with us

Microbes Down on the Farm

Written by
Just 20 years after the classic, well-reasoned argument addressing the question “What is a Pathogen?” by Stanley Falkow, we are now confronting a similarly persuasive case against the very word “pathogen”!   A thoughtful argument against “healthy” vs. “unhealthy” microbiomes has also been made.
