It is (almost boringly) obvious that cell-to-cell communication is vital in multicellular organisms. To function properly, all cells in a tissue have to know – and let their neighbors know – where exactly they are, which tasks they're performing right now, when it's time to differenti... Read More

The TWiVeroos examine a reverse spillover of Newcastle disease virus vaccines into wild birds, and identification of a protein cell receptor for murine noroviruses.
Host: Jeff Fox with special guests, Julia Yeomans and Vikas Berry.
Julia Yeomans of Oxford University in the United Kingdom and chemical engineer
Microbial infection is implicated in an ever-growing number of types of cancer. Adding to the already long list of microbial-associated cancers, an increasing body of evidence suggests breast cancer may also be associated with a specific microbial milieu. A report in Applied and Environmental Mi... Read More
Vincent Racaniello of the This Week in Virology podcast interviews Phillip Sharp, PhD, about his career and professional experience in the field of virology. Sharp's research interests have centered on the molecular biology of gene expression relevant to cancer and the mechanisms of RNA splicing... Read More
Ananda Chakrabarty, PhD, Distinguished University Professor, University of Illinois College of Medicine at Chicago, discuses how certain pathogenic bacteria, pseudomonas aeruginosa and neisseria menigitidis, secrete protein weapons (azurin and laz) to fight cancer, providing our next generation ...

Hurricane Matthew hit Haiti on October 4, 2016, and the southeast United States two days later, leaving tens of thousands without power, transportation, and in the worst cases, homes. Because of its extreme poverty, and its continuing recovery from previous natural disasters, Haiti is looking at... Read More
Barry Bochner with Biolog, Inc., presents an ASM Virtual Lecture on phenomics, a relatively new technology that can be applied with diverse microbial cells to expand our understanding of the effect of genetic or environmental changes on cells.
ASM’s virtual lectures are conducted by fellows ... Read More
Daniel Haeusser, an Assistant Professor in the Biology Department of Canisius College in Buffalo, New York, discusses the misconception of assuming that photosynthesis exists as single process of strict coupling between energy conversion and carbohydrate production. Read More
This episode: Slime molds have special cells that capture and kill bacteria using traps made of DNA!

Sharon and Scott join the TWiV team to talk about their work on dengue antibody-dependent enhancement of Zika virus infection, and identifying the virus in mosquitoes from Miami.
The TWiM team discusses the importance of neutrophils in microbial infections, and evidence that ancient bacteria had two cell walls.
Microbes are excellent at adapting to stressful situations, which is part of the reason antibiotic resistance is a problem today. Constant exposure to antimicrobials such as triclosan have selected for resistant strains, rendering the compound ineffective. This is why the FDA recently banned t... Read More
A new 3-D printed, easily assembled smartphone microscope developed at Stanford University turns microbiology into game time. The device allows kids to play games or make more serious observations with miniature light-seeking microbes called Euglena.
When it’s assembled, it has a platform for... Read More
In an attempt to preserve and defend the good name of the salmon fished in his state, Senator Warren Magnuson (D-WA), introduced in 1969 a bill in the US Senate proposing to change the name of Salmonella to the more inoccuous sounding Sanella. In some circles it may seem comforting to th... Read More
Two vaccines against Zika virus developed at the University of Pittsburgh School of Medicine have successfully conveyed immunity from female mice to pups conceived weeks after the mother's vaccination.
When challenged with Zika virus within a week of their birth, both vaccines protected the p... Read More
A new study shows that when heat-susceptible bacteria living symbiotically in the guts of insects are exposed to increased temperatures, both the bacteria and the insect are negatively impacted and can die. The study, reported online this week in the journal mBio®, illustrates another way globa... Read More
The Nobel Prize for Medicine this year went to Dr. Yoshinori Ohsumi of the Tokyo Institute for Technology for his work on autophagy, the process of digesting unneeded or damaged cellular components. This process plays a role in many central cellular activities, with applications ranging from gen... Read More
