During the winter of 1962 in California, a new virus was isolated from the oropharynx of 4 children who had been hospitalized with respiratory disease that included pneumonia and bronchiolitis. On the basis of its physical, chemical, and biological properties, the virus was classified as an ente... Read More
I liked the discussion of the interaction of bacteria and Leishmania in sandfly guts; it was very interesting! Here is another suggestion if you need a topic to discuss:

Hey Vincent, Elio, Michele and Michael!
I'm a first year microbiology graduate student at UC Berkeley and an avid listener of twim. Elio's snippet from the most recent podcast reminded me of a personal anecdote that might be useful to share with... Read More
Jason Roberts, a virologist at the Victorian Infectious Disease Reference Laboratory in Melbourne, Australia, creates three-dimensional simulations of viruses showing how the molecules that make up the capsid and genome might move in very short periods of time. I visited Jason in his laboratory ... Read More
Vincent, Dickson, and Daniel reveal last week's case study and introduce a new one concerning a patient who traveled to Belize.
Many people have a new awareness of the disease known as amyotrophic lateral sclerosis, or ALS, thanks to the Ice Bucket Challenge initiated by the ALS Association. Fewer might know that retroviruses have been proposed to play a role in the development of the disease. Read More
Scientist has described the possible existence of sixth DNA base, the methyl-adenine (mA) this week.
Deoxyribonucleic acid (DNA) is a polymer of nucleotides, which encodes every genetic information of living existence. The entire genetic information are stored within DNA as the form of millio... Read More
Antigenic variation is a hallmark of influenza virus that allows the virus to evade host defenses. Consequently influenza vaccines need to be reformulated frequently to keep up with changing viruses. In contrast, antigenic variation is not a hallmark of poliovirus – the same poliovirus vaccines ... Read More
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
Given the extent of the Ebola virus outbreak in West Africa, transport of an infected individual to the US was bound to happen. The case is an adult who had contact with an Ebola virus-infected woman in Liberia, then traveled to Dallas. He had no symptoms before arriving in the US and therefore ... Read More
New Massive Online Open Courses (MOOC) in Spanish about Pandemics and new viral infections.
An online open course about basic concepts of viruses and pandemics. We answer questions as what is a virus?, how a virus multiplies inside a cell?, what is a pandemic?, why appear new influenza virus ... Read More
I am a retired computer programmer and also a free market libertarian. I listened to a recent podcast where the subject of mandatory hand washing by food workers was tossed around. I would like to present a few more of the free marke... Read More
You've probably gone a few days without showering -- maybe a week. But let's say you don't bathe for days on end -- as in you use no soap, no water, no nothing.
What would happen?
