Segmented genomes abound in the RNA virus world. They are found in virus particles from different families, and can be double stranded (Reoviridae) or single stranded of (+) (Closteroviridae) or (-) (Orthomyxoviridae) polarity. Our recent discussion of the advantages of a segmented viral genome,... Read More
For what may be the first time, researchers have discovered a virus inside a host with a non-standard nuclear genetic code — one that differs from the standard genetic code that almost all living things use to produce proteins.
“The finding is significant because it shows that these viruses... Read More
Recording together for the first time, the TWiV team celebrates their 300th recording at the American Society for Microbiology headquarters in Washington, DC, where Vincent speaks with Dickson, Alan, Rich, and Kathy about their careers in science.

In this blog entry, I discuss the perennial problem for educators: helping students find study strategies that help them reach their educational goals. I have found that student-generated study material is most helpful...and is sometimes quite artistic! Read More
The journal "RNA Biology" just published a memorial issue dedicated to the late, great Carl Woese. The entire issue is open access. I have a small contribution, but the entire issue is filled with great science, wonderful memories, and a fine celebration of a scientist who changed the way we l... 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

In this blog post, I discuss how students begin to find their "path" to a career that they will love in science. I aIso write about the late, great Richard Feynman. Read More
Until recently cancers were seen as lifestyle and genetic diseases, brought on by exposure to carcinogens or a mutated gene. Recent studies are linking microbes to many diffe... Read More
In this blog post, I describe some "rules for academics" as well as my own "rules for research." I hope that readers find them useful and perhaps a bit humorous. Read More
It is a well recognized uncommon cause of skin and nail infection of the hands and feet . Unlike Dermatophytosis these mould infections are not contagious. There are few reports of invasive infection caused by N. dimidiatum; most infections occurred in immunocompromised hosts. Arthrospores ar... Read More
Suzanne writes (re Aphids):
The best way to get rid of aphids in the garden (the ants in my yard love to herd them onto my okra) is a sharp stream of water from the hose. Aphids wash right off! They don't tend to come back right away, either.
Recently, the American Academy of Microbiology released a new report, Viruses Throughout Life & Time: Friends, Foes, Change Agents that delves into the origin of viruses, the overlooked biological and microbial ecological role of viruses, and how these live forms have contributed to evolution. T... 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
In this post from my blog, I discuss the recent interest in snarky-funny academic hashtags on Twitter, such as #overlyhonestsyllabi. Just like students, educators need to blow off some steam (especially as classes approach!). But it is also important to remember our educational goals, and matc... Read More
Researchers report the detection of a strain of Seoul hantavirus (SEOV) in pet rats in England and Wales. The discovery followed an investigation of a case of haemorrhagic fever with renal syndrome in Wales. Hantavirus RNA was detected via real-time reverse transcription-polymerase chain reactio...

In this blog entry, I describe how working with the artist Katie McKissick ("Beatrice the Biologist") helped improve my freshman biology course. The intersection of biology and art benefits both! Read More
On this Mothers' Day, I reflect on the role my late mother had on my own decision to become a scientist. We all owe are mothers a great deal, and not just for the mitochondria! So hurray for mothers everywhere! Read More
Wine grapes present a unique biogeography model, wherein microbial biodiversity patterns across viticultural zones not only answer questions of dispersal and community maintenance, they are also an inherent component of the quality, consumer acceptance, and economic appreciation of a culturally ...
