THE MAKING OF... MY FIRST TEDx PRESENTATION
Being part of a TEDx event was an incredible experience. I loved every minute of it, and should thank the organizers for setting up such an amazing event. At around 14.30 hrs it was showtime, and my stories on cheese, dogs, and a pill to kill mosquitoes were presented. There I was, in front of a huge audience, in bed, wearing boxer shorts. The idea for this did not come from me. I owe it to Inga, my wife. She thought of the idea to start the show in bed...
My first story focused on Limburger cheese as an attractant for malaria mosquitoes. What better to start with in the heart of Limburg than this story. The research that got us focusing on foot odour, by putting a naked volunteer in a cage and releasing mosquitoes into it to see where they were biting, was published in 1995 (1). By the way, I was the naked volunteer. My former colleague Ruurd de Jong was the one releasing mosquitoes. In 1996 we published the work on the cheese (2). For this work, in 2006, Ruurd and I received the IgNobel Prize in Biology at Harvard University (3). Since then we worked on the fatty acids, lactic acid, and ammonia that is found in the aroma of Limburger cheese, and the story about this mixture being 2-3 times more attractive to mosquitoes than humans was published by friend and colleague Fredros Okumu and others (4).
The story that I presented about dogs, and how we can use them to fight malaria is very new. In fact, we only started working on this idea recently. It was the huge expertise of Ellen van der Zweep, of Llanfarian border collies, and Winny Kolder, of the Dutch police force, that was crucial for this success. They managed, within 8 weeks, to train Tweed (the dog in the video) to learn the smell of mosquito larvae. I am excited to report here that soon Ellen and I will fly out to the tropics to work with Tweed in the field!
The story of the mosquito-killing pill was born after I attended a lecture about new drugs, and reasoned that the compound we used might work against mosquitoes. Online, there is a lot of speculation about human safety of this drug, but this looks very promising - it is toxic to insects, but harmless to humans. We have filed a patent for this invention in October 2011, and are now looking for partners (and funding!) to bring this drug to the market. I hope that Bill Gates will see the video ;-). The video that I showed for this - killing mosquitoes after taking a pill, was shot by Dr. Hans Smid, a macro photography specialist at 'Bugs in the Picture', for which I am very grateful indeed.
