During my visit to Berkeley, CA to record TWiV #228, I met Deb Sklut, an artist who is inspired by the power of science. I recorded a brief conversation with Deb which you can view below. Her work can be found at SqueakySqueegeeArt.etsy.com. Read More
Middle Eastern respiratory syndrome coronavirus (MERS-CoV), first identified in the fall of 2012 in a Saudi Arabian patient, has since infected over 160 individuals, causing 71 deaths. Identifying the source of infection is important for efforts to prevent further infections. Recently two studie... Read More
Virologist John Holland passed away on 11 October 2013. I asked former members of his laboratory for their thoughts on his career and what he meant to them. Read More
The microbes that call the New York City subway system home are mostly harmless, but include samples of disease-causing bacteria that are resistant to drugs — and even DNA fragments associated with anthrax and Bubonic plague — according to a citywide microbiome map published today by Weill Corne...

Wild poliovirus has been detected in the sewers of Brazil and Israel. Fortunately, no cases of poliomyelitis have been reported in either country. Why is poliovirus present in these countries and what are the implications for the eradication effort?
Wild type poliovirus (e.g. not vaccine-deri... Read More
Infection with influenza virus is known to increase susceptibility to bacterial infections of the respiratory tract. In a mouse model of influenza, increased bacterial colonization was also observed after administration of an infectious, attenuated influenza virus vaccine. Primary influenza viru... Read More
My wife, who is a mathematician and artist, made a stop motion video using Play-Doh that represents the life cycle of the bacterial predator, Bdellovibrio. This brings together interesting microbes, animation, and thoughts about what students might do to understand processes in microbiology! Read More
'The question of whether someone should be taking a probiotic or an antibiotic is one I hear fairly frequently. The answer, in short, is that this isn't a question of either / or! At this stage in time, with this level of research on probiotics, it is not right to suggest one stops taking their... Read More
ASM2014 tiene "sabor Latino". Por primera vez podrás participar de ASM ¡en vivo! Tendremos una sección solo en Español donde las anfitrionas, Greetchen y Catalina (Mundo de l... Read More
The stability of Middle East respiratory syndrome coronavirus (MERS-CoV) was determined at 20°C – 40% relative humidity (RH); 30°C – 30% RH and 30°C – 80% RH. MERS-CoV was more stable at low temperature/low humidity conditions and could still be recovered after 48 hours. During aerosolisation of... Read More
Based on a Twitter conversation with two microbiology educators, I share a story of how (through a survey) I encourage students to look deeply at their study strategies and promote "ownership" in their classroom experience. Read More
This episode: Genes taken from bacteria may have been important for the evolution of distinct groups of archaea!
(7.4 MB, 8 minutes)
By evaluating the bacteria and fungi found in fossilized feces, microbiologists are providing evidence to help support archeologists' hypotheses regarding cultures living in the Caribbean over 1,500 years ago. Researchers discuss how the analysis of 1,500-year-old coprolites from archeologica... Read More
PLOS ONE authors Cybulski, Clements and Prakash describe an ultra-low-cost origami-based approach for large-scale manufacturing of microscopes, specifically demonstrating brightfield, darkfield, and fluorescence microscopes. Merging principles of optical design with origami enables high-volume f... Read More
Genomes of non-defective viruses range in size from 2,400,000 bp of dsDNA (Pandoravirus salinus) to 1,759 bp of ssDNA (porcine circovirus). Are even smaller viral genomes possible? The subviral agents called viroids provide an answer to this question.
Viroids, the smallest known pathogens, ar... Read More
In this blog post, I describe how I use the commonly available pGLO plasmid to teach freshman students basic concepts about transformation, receptor recognition, drug resistance mechanisms, and gene regulation. Oh, and fluorescence via GFP! Read More
Reticuloendotheliosis viruses (REVs) are retroviruses that cause a rare disease of gamebirds and waterfowl that includes anemia, immunosuppression, neoplasia, runting, and abnormal feathering. Since the first isolation of REV from a turkey in 1957, REVs were believed to be strictly avian viruses... Read More

Satellites are subviral agents that differ from viroids because they depend on the presence of a helper virus for their propagation. Satellite viruses are particles that contain nucleic acid genomes encoding a structural protein that encapsidates the satellite genome. Satellite RNAs do not encod... Read More
Most gut bacteria are beneficial, aiding food digestion, producing vitamins, and protecting against harmful bacteria. If left unchecked, however, harmful bacteria can excrete... Read More
