A simple new method better assesses the risks posed by emerging zoonotic viruses (those transmissible from animals to humans), according to a study published in PLOS Medicine this week. Dr. Simon Cauchemez and colleagues from Imperial College London in the UK and the Centers for Disease Control ... Read More
Dr. Naowarat Cheeptham, is a famous cave microbiologist. Dr. Cheeptham has been fascinated with the world of biology since she was out catching butterflies as a child with her father in her native country, Thailand. Her interest in microbiology developed while studying at Chiang Mai University ... Read More
Microbes can tailor transcriptional responses to diverse environmental challenges despite having streamlined genomes and a limited number of regulators. We present data‐driven models that capture the dynamic interplay of the environment and genome‐encoded regulatory programs of two types of prok... Read More
Chefs from top-notch restaurants are reaching out to microbiologists, seeking advice that goes beyond traditional food safety or conventional food-processing concerns. With or without professional scientific advice, some chefs and food producers are doing their own microbiological experiments, s... Read More
Popular Science has just launched a new science blogging network with 13 blogs. Among them are two that have a focus on microbiology, Under the Microscope by JA Tetro and Our Modern Plague by Brooke Borel. Each blog has an inaugural post that outlines the author's vision for future subject matte... Read More
A CNN iReport about an integrative lab series known as the Wolbachia in Nashville includes area high school students from School for Science and Math at Vanderbilt with the purpose of bringing real-world scientific research on microbes into high school biology classes. Angela Eeds, director with... Read More
Dear TWIM hosts,
I enjoyed episode 76, "Genetic biopixels and a pathogenic sweet tooth". I really enjoyed hearing about the course that Dr. Schaechter teaches and in particular the work his students did in developing the biosensor. I would like to ... Read More
Poliovirus has been found in sewage in Israel. The virus detected is not vaccine-derived poliovirus; it is wild-type 1 poliovirus, the strain that occurs naturally in the wild and which the World Health Organization is trying very hard to eradicate from the planet. Read More
Rare is the holiday meal that does not owe many of its pleasures to invisible cooks with tongue-twisting names. Do you enjoy charcuterie and pickles? Bread with cultured butter? A drizzle of vinaigrette on this or that? A bit of cheese? Some chocolates? Wine, beer or cider? Then raise a glass to... Read More
Pharmaceutical experts NSF DBA have created an interactive guide to hand washing.
Recently a number of children in California have developed a poliomyelitis-like paralysis. The cause of this paralysis is not yet known, and information about the outbreak is scarce. However, acute-flaccid paralysis is not uncommon (California would be expected to report about 75 cases a year, b... Read More
Miravirsen is a drug that binds to and blocks the function of a cellular microRNA called miR-122 that is required for the replication of hepatitis C virus (HCV). Treatment of chimpanzees chronically infected with HCV with this drug leads to suppression of viral replication. The results of a phas... Read More
Virologist Hilary Koprowski died on 11 April 2013 at the age of 96. His main accomplishments are nicely summarized in the New York Times, but for a more comprehensive overview of his life, I highly recommend his biography Listen to the Music by Roger Vaughan. I did not have many opportunities to... Read More
About eight percent of human DNA is viral – remnants of ancestral infections with retroviruses. These endogenous retroviral sequences do not produce infectious viruses, and most are considered to be junk DNA. But some of them provide important functions. The protein called syncytin, which is ess... Read More
The Twivsters discuss how reverse transcriptase encoded in the human genome might produce DNA copies of RNA viruses in infected cells.
The influenza virus particle is made up of the viral RNA genome wrapped in a lipid membrane (illustrated). The membrane, or envelope, contains three different kinds of viral proteins. The hemagglutinin molecule (HA, blue) attaches to cell receptors and initiates the process of virus entry into c... Read More
Where does the virus come from? How is it spread? Can we predict when and where outbreaks will occur? What factors determine how sick a person will become if they are infected with West Nile virus?
To help answer the many questions people have about this multi-faceted virus, the American Acad... Read More
Hi Dr.s R&D,
I thought you might be interested in this news article about aquaculture in Hong Kong. Perhaps it's time for another fish parasite episode? I love the podcast, keep up the great work.

This is an accurate visualization of the Bacteriophage T4 based on Cryo-EM datasets of the virus. The scope of the animation is to show the infection process of the T4 into an E. coli cell. All scientific data sets and motion based off of research from Michael Rossmann Laboratory (Purdue Univers... Read More
