The TWiVoids discuss the March for Science, the GOF moratorium, and a classic virology paper on mapping the gene order for vesicular stomatitis virus.
Mentoring scientific teams in a project-oriented competition, like engineers can do through the ASCE Concrete Canoe National Competition or the SAE Supermileage Competition, is rare in the microbial sciences. Mentoring a team through this experience allows scientists impart different skills than... Read More
The last time you had a stomach bug, you probably didn’t feel much like eating. This loss of appetite is part of your body’s normal response to an illness but is not well understood. Sometimes eating less during illness promotes a faster recovery, but other times—such as when cancer patients exp... Read More
Restricting the use of a common antibiotic was more important than a high profile 'deep clean' of hospitals in massively reducing UK antibiotic resistant Clostridium difficile (C. diff) cases, a major new study has found.
The study concluded that overuse of antibiotics like ciprofloxacin led... Read More
Scientists at the University of Rochester School of Medicine and Dentistry have developed, for the first time, two new vaccines for canine influenza. This research is not only important for improving the health of our furry friends, but for keeping us safe, too. Dogs that have been infected with... Read More
In a joint study, published today (Friday 27 January) in the journal Nature Communications, scientists from the Centro Nacional de Biotecnología in Madrid and the University of Sussex / Brighton and Sussex Medical School in Brighton report the discovery of a gene called NucS that dramatically re...

What Silicon Valley is to technology, Kansas State University is to biodefense.
When former Senate Majority Leader Tom Daschle and the bipartisan Blue Ribbon Study Panel on Biodefense visited the Manhattan campus on Thursday, Jan. 26, for a series of agrodefense discussions, the university ce... Read More
When biochemists deciphered the genetic code in the 1960s (the triplet 'alphabet' for amino acids whose defined order make up the protein 'words' ) it was – and still is – the most compelling evidence for a common "descent with modifications" (Charles Darwin) of all life on Earth: the alpha...

The sages of TWiV explain how chronic wasting disease of cervids could be caused by spontaneous misfolding of prion protein, and the role of the membrane protein Axl in Zika virus entry into cells.

The Coalition for Epidemic Preparedness Innovation (CEPI) hopes to prevent future outbreaks by generating, testing, and storing vaccines before outbreaks occur. How do you design a vaccine before a prevailing serotype is determined? Read More
It’s winter in the northern hemisphere and many are itching to hit the sun and sand in an exotic location. I, myself, took leave from the cold weather and spent several weeks this January traveling through India. This is the first time I travelled to Asia, and it took slightly more than a few mo...

The TWiMers discuss how changes in domestic laundering affect the removal of microorganisms, and assembly of a nucleus-like structure during viral replication in bacteria.
Hey there TWIM team
I am a Veterinary Microbiologist in Cork in Ireland!
Long time listener of all the TWIX series and I love everyone of them.
I work in a diagnostic lab in cork and the only thing that gets me through the day is ... Read More
One of the most important aspects of a new laboratory protocol is its reproducibility (as previously discussed on ASM’s Microbial Sciences blog). A protocol must produce the same results when performed by different scientists at different labs, and this is especially important when considering n... Read More
If you live with pets, you know where their tongue has been, yet you let them kiss and lick you all they want without even thinking twice about it. I've heard people say that a dog's mouth is very clean, and that their saliva, delivered by licking, can help heal wounds, but is that really true?

“There are many gut microbiome studies on humans and rodents, but not a whole lot on dogs, in particular,” says Johnny Li, a computational biologist at the Nestle Purina PetCare Company, in St. Louis. He recently led a study on the connection between diet and intestinal bacteria on 64 dogs — 32 ... Read More
Viruses may be stealthy invaders, but a study at the Weizmann Institute of Science reveals a new, chatty side of some: For the first time, viruses have been found communicating with one another. This communication – short “posts” left for kin and descendants – helps the viruses reading them to d... Read More
Scientists have discovered how a unique bacterial enzyme can blunt the body’s key weapons in its fight against infection.
Researchers at the University of Illinois at Urbana-Champaign and Newcastle University in the U.K. are investigating how infectious microbes can survive attacks by the bod... Read More
