We must change how antibiotics are used and adopt proactive strategies, similar to those used to save endangered species. Preservation of the efficacy of antibiotics and to stabilization of antibiotic-susceptible bacterial ecosystems should be global goals.
We urge all of you to participate i... 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

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
Vincent and Dickson discuss how nibbling of human cells by Entamoeba histolytica, a process called amoebic trogocytosis, contributes to cell killing and tissue invasion.

Liquids are capable of forming a gas-liquid interface: maintenance of the surface requires adequate pressure in the gas. Adequate in this instance means a gas pressure greater than the vaporisation pressure in the liquid. The gas pressure... 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
Have you ever wondered why mozzarella bubbling and stretching between pizza slices is so different from the earthy flavors of blue-veined gorgonzola? The diversity of cheeses we love are created by encouraging and manipulating the growth of specific microbes. The American Socie... Read More

The Twivsters discuss how reverse transcriptase encoded in the human genome might produce DNA copies of RNA viruses in infected cells.
Ten years ago this month I wrote the first post at virology blog, entitled Are viruses living? Thanks to EE Giorgi for pointing out the ten year anniversary, and also for publishing an interview with me at her blog, Chimeras. Here is how this blog got started. Read More
Nuevas guías de la Agencia de Protección Ambiental (USEPA) para las aguas recreacionales: éste es el tópico que discutiremos hoy con Grace Robiou, quien ha trabajado durante los últimos años buscando nuevos indicadores de riesgo que protejan mejor a los bañistas.
Aunque en el mu... Read More
Matt updates the TWiV team on MERS-coronavirus, and joins in a discussion of whether we should further regulate research on potentially pandemic pathogens.
