Viruses can be broadly classified according to whether or not the particle is enveloped – surrounded by a membrane taken from the host cell – or naked. Some naked viruses apparently are more modest than we believed. Read More

I just listened to the latest TWiM. Thanks for covering our horizontal gene transfer paper! It was great to hear you all talk about it and give your thoughts.
With regards to the selective pressure for retention of the Dae’s in genomes o... Read More

Vincent, Dickson, and Daniel explain how trypanolytic factor forms membrane channels to lyse trypanosomes, and present a new case study.
This is fun, and although I'm sure someone will gripe about Dicksons enthusiastic response to the crayfish, it made my life easier. I think it's Paragonimus kellicoti. As for eating raw crayfish; how drunk... Read More

My experience with Foldscope, the paper microscope. See the images of insects, parasites, vegetal and animal tissues and cells, yeast, bacteria and (almost) virus (the cytopathic effect), with Foldscope, the paper microscope (text in Spanish). Read More

Vincent, Dickson, and Daniel consider the delivery of anti-trypanosome nanobodies to the tsetse fly via a bacterial symbiont, and present a new case study.
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:
Delivery of a functional anti-trypanoso... Read More
Plants and Microorganisms are the major sources of drugs till date. Most of these "natural products" come from a few genera of soil and marine bacteria that have long been known for their prolific chemistry. The classical process of discovering drugs from microorganisms have two drawbacks- it is... Read More
Because viruses must bind to cell surface molecules to initiate replication, the use of soluble receptors to block virus infection has long been an attractive therapeutic option. Soluble receptors have been developed that block infection with rhinoviruses and HIV-1, but these have not been licen... Read More
