Nitin Phadnis joins Nels and Vincent to explain how he identified a gene that is responsible for male inviability in hybrids from a cross between two species of fruit flies. Read More
The previous post mentioned the onset of antibiotic resistance as one of the scarier, if less sensationalist, outbreaks of our time. We generally discuss antibiotic resistance in medically relevant microbes (on this blog and in the news), where resistance means the ability of disease-causing mic... Read More
Drug-resistant infections are becoming one of the scariest epidemics since the advent of antibiotic discovery. Although microbes like methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Klebsiella pneumoniae, and multidrug-resistant Pseudomonas aeruginosa are responsible for... Read More
Imagine taking an ocean-side vacation, with the sun, sand, and water lulling you to relaxed bliss. After day at the beach, you experience an intense bout of stomach cramps and – more delicately put – GI distress. A rare day off is ruined because of a bug you picked up. Next, imagine a situation ... Read More
In four months, 155 countries will together switch from using trivalent to bivalent oral poliovirus vaccine. Will this change lead to more cases of poliomyelitis? Read More
Los virus son considerados por la mayoría como patógenos en todo tipo de entidades biológicas. Sin embargo la gran mayoría de los virus son inocuos a sus células hospedero. Nuestro invitado de hoy, el Dr. Paolo Zanotto es investigador y profesor en la Universidad de Sao Paolo, Bra... Read More
Feeling a bit under the weather? There’s a decent chance you’re suffering from an infection with an enterovirus. Enteroviruses are a commonly encountered virus, especially in the summer and fall. They can cause a variety of symptoms, from cold-like symptoms such as runny nose or fever to more se... Read More
The TWiP trifecta solves the case of the Woman from Bolivia with Belly Pain, and discuss a method for population modification of malaria mosquitoes using a Cas9-mediated driver gene.

In episode #3 of the new science show This Week in Evolution, Nels and Vincent examine another important driver of evolution: recombination. The results of two papers in which the process is studied in finches and in yeast lead to the unexpected conclusion that recombination evolves more slowly ... Read More
As we’ve seen in numerous cases in 2015, food contamination is a real issue for a number of different food types. Vegetable, meat, packaged, fresh – even pet food – we’ve seen too many examples of how bacteria can outsmart our best food safety practices. The Canadian government estimates 1 of ev... Read More
I have worked on poliovirus for over thirty-six years, first as a posdoctoral fellow with David Baltimore in 1979, and then in my laboratory at Columbia University. The end of that research commences this year with the destruction of my stocks of polioviruses. Read More
Host: Jeff Fox with special guest, Stijn Mertens.
Mertens, a graduate student working with Kevin Verstrepen at the University of Leuven in Belgium, talks with Jeff Fox about their efforts to develop new yeast strains for making lager beers—imparting novel flavor and aroma notes withou... Read More
How does a single-celled organism ‘know’ how to respond to its environmental conditions? Understanding microbial cell signaling is one way to determine how bacteria will react in a particular setting. In the past decade, researchers have revealed a significant role for cyclic-di-GMP in bacterial... Read More
I made this video in October of 2015, with my Biology 350 Microbiology students at the University of Puget Sound. A drop of Pseudomonas syringae expressing ice nucleation protein hits supercooled pure water, and fun results. This is the way that Snomax works to commercially generate snow, inci... Read More
