Bug Researchers Are Digitising Their Collections of Skewered Insects

Air mailing tiny biological specimens to entomologists in different countries is full of risks. Sometimes they get destroyed en route to their destination or even lost in the post.
Researchers from Berlin’s Museum of Natural History want to tackle these problems with a project dubbed “Zoosphere.” For this project, they’ve digitized around 80 insect specimens from a collection of several million so they can share them without risk of losing the originals.
“We don’t like sending out insects as occasionally they get lost in the post. We’re no longer sending them out to researchers in emerging countries, and that leaves them handicapped if they don’t have the resources to come to us,” Thomas von Rintelen, Zoosphere project manager, told me over the phone.
“Zoosphere is a tool that delivers 3D images of these specimens. It lets us open up our collections to everyone free of charge.”
To image a specimen, researchers retrieve it from its drawer, mount it on a special holding tray, then twirl it around so that a camera can capture it from all angles. The process takes several hours and the researchers end up with several hundred images with which to make their 3D virtual bug image. The final result allows users to access the bug and view it from all angles on their computer screen. The images are linked to a species name, and used as a reference point by entomologists when they are describing and categorizing similar species from the same family.
According to Martin Pluta, a biologist and programmer at Berlin’s Museum of Natural Science, the digital models offer some advantages over the physical copies. Everyone can access these models, and users can zoom and view the images at any angle without worrying about damaging them, and use the images in research papers. Most importantly, the digital images override the need for the museum to send out precious type specimens. These are the specimens upon which the name and description of a new species is based.
I'm sorry..but I will need more proof than I have seen so far. If you believe I accept what you all have accepted then by the same measure, you must accept that I must be smoking something in this splendid and smart pipe that I know for a fact I am not smoking ... unless, of course, understanding cause and effect as only I can, someone.. someone on this thread placed it there... and that my dear aspiring applicants to the vacancy left by my esteemed colleague,Watson ..is unacceptable.
