Hello Dr Racaniello and Despommier,
I recently saw an article about the paper linked below on Science Daily and thought it might be worth a discussion on TWIP. It is about the possibility of bed bugs being a vector for T. cruzi. I would love to... Read More
Since vaccines have been so successful at controlling diseases like smallpox and polio in the United States, we often take our relatively epidemic-free world for granted. But less than a lifetime ago, these diseases and others were still real threats to health. Despite vaccines’ successes, many ... Read More

Dear Vincent and Dickson,
Listening to TWiP on cyclosporiasis. Because I am all too aware of the possible contamination of many crops as a former public health nurse who worked in epidemiology for my state (Florida), I always wash my fruits and v... Read More
PLoS One has published an interesting paper that considers using smart phones for scientific field data collection and suggests mobile apps could also be beneficial for recruiting ‘citizen scientists’ to contribute data easily to central databases through their mobile phone.
Here's the abstr... Read More
Viruses can act as miniature couriers. When they infect, they may inadvertently take up a bit of their host’s DNA and have it copied into their progeny. When the offspring viruses move on to infect new cells, they may insert this bit of accidentally pilfered DNA into the new hosts’ genome. This ... Read More
