  I am told here at the NHM London that relaxed material is almost useless for DNA, but i have not reference only word from other lepidopterists.

  Racism noun [mass noun] the belief that all members of each race possess characteristics, abilities, or qualities specific to that race, especially so as to distinguish it as inferior or superior to another race or races: theories of racism prejudice, discrimination, or antagonism directed against someone of a different race based on the belief that one’s own race is superior: Oxford Dioctionary (http://oxforddictionaries.com/definition/english/racism) Unless you are suggesting that biologists (systematists) have prejudice, discriminate towards different subspecies or they themselves believe they are a superior race of the organism they study then I dont understand your comparison. but it might be me

  Hey Benjamin I know the work you guys do in Jena it is awesome. I was actually thinking about applying for some money to come do some imaging there. The work I am doing is far from that advanced. I am actually working with a DSLR (with a macro lens) and a turntable. this allows me to take about 100-200 images around the insect and then create a point cloud that can be made into a model. Although µ-ct is the way to go this is a small pet project of mine, that if it works could make my life as a morphologist a lot easier..

  Has anyone been playing with photosynth to create point clouds of small animals. I have had considerable success using it on Insects. Still have a long way to go as I am still not good enough with meshlab and blender to complete my 3d models. Would love to hear some opinions and helpful hints from people who have tried this.

  Hi I am a biologist working with insects. I recently came across an ant species that makes a very interesting entrance to it's nest. The entrance is basically a cylindrical hole with a funnel shaped entrance in the middle. The funnel does not extend above the cylindrical hole. I have been pondering what the design of this entrance is for and it struck me that it might have some thing to do with ventilation. So here is the question how do I go about measuring the airflow over the surface to see if the turbulence can suck out air from the entrance ? Or is this even possible?
