Food-related microbiology can be one of the most fun - or least fun - ways to interact with microbes. In the ‘most fun’ category, scientists and non-scientists alike can use microbes to create delicious foods from fermentative processes; in the ‘least fun’ category, scientists and non-scientists...

Communication of experimental results via publishing is one of the most important steps of the scientific method; if you don’t share your results, how will knowledge within a field grow? A well-written article contextualizes the author’s data into a broader scientific landscape, which allows rea... Read More
This episode: Cyanobacteria in biocrusts produce pigments that heat their surroundings up to 10 degrees hotter!
(7 MB, 7.6 minutes)
How is it that we are we able to devote so little of our personal time and energy to producing or acquiring the healthy, safe food that we consume multiple times every day? A large part of the reason we seldom worry about agricultural output is that most of us benefit enormously from modernized,... Read More
This episode: Spherical cyanobacterium Synechocystis acts like a tiny eyeball in sensing light, allowing cells to move closer to light sources!

Given the complexity of host-microbiota symbioses, scientists and philosophers are asking questions at new biological levels of hierarchical organization—what is a holobiont and hologenome? When should this vocabulary be applied? Are these concepts a null hypothesis for host-microbe systems or l... Read More

Vincent Racaniello of the This Week in Virology podcast interviews Neal Nathanson, MD, about his career and professional experience in the field of virology. Nathanson's work has focused on the epidemiology and eradication of poliomyelitis, the control of the HIV/AIDS pandemic and the developmen... Read More
Evidence suggests that microbes existed on Earth as far back as 3.7 billion years ago, a billion years after the planet formed. Animal remains, however, don't appear in the fossil record until 600 million years ago during the Ediacaran period, though there are indirect signs that animal life may... Read More
Dear Vincent, Elio, Michael, and Michelle,
I've just recently finished TWiM number 133 and wanted to comment about the use of the term "secondary metabolite" throughout the episode and often in the primary literature. Michael pointed out that a se... Read More
"Hivi and his team of viruses (Ebola, Pox,..etc) believe they can win the battle, but the Virologists (who are real famous professors) beat them. However, new viruses pop-up, it will be a long battle. This makes the story very interesting and ever so engaging."

Researchers at the Okinawa Institute of Science and Technology Graduate University in Japan are exploring the possibility of disrupting infections by modifying the flagella of infected bacteria. They are doing this by modifying a protein outside of the bacteria and then re-inserting into the ba... Read More
In a creative stroke inspired by Hollywood wizardry, Harvard scientists have designed a simple way to observe how bacteria move as they become impervious to drugs. The experiments are thought to provide the first large-scale glimpse of the maneuvers of bacteria as they encounter increasingly hig... Read More
The world's oceans teem with scientific mystery, unknowns that could prove to be tools that will one day protect the planet from global warming.
An international research team now reports they've tripled the known types of viruses living in waters around the globe and have a better idea what ... Read More
With California in its fifth year of severe drought and many western states experiencing another year of unusually dry conditions, plants are stressed.
Agricultural crops, grasses and garden plants alike can get sick and die when factors such as drought and excess sun force them to work harde... Read More
Fungi from Santiria apiculata rhizosphere grown on water agar, 14 days incubation period. With the same morphological appearances, there is a strong cross communication, thus creating zones of inhibition. Read More
The BBSRC and NERC-funded ShellEye project seeks to help shellfish farmers manage threats from harmful algal blooms and E. coli bacteria. The multi-partner ShellEye project brings together industry, government and scientists and aims to develop a satellite-based forecasting system to help fisher... Read More
