Terwijl andere studenten over de boeken gebogen zaten, bivakkeerde de feestcommissie van S.V. Life (de studentenvereniging voor life science & technology, zie sylife.n
l) afgelopen maandag in een koetent. Dit om aandacht te vragen voor hun feest van 25 april met als thema ‘Boer zoekt Habibi: Van nijlpaard tot kamelenteen, waar ga je met je harem heen?’ Voeg daarbij de biertjes voor een euro en een optreden van Barry Badpak op Quintus in Leiden. Maar ja, eerst die tentamens.
He took the photo himself, Dr Jason Pierson notes, after his appeal to Old Amsterdam for high-res pictures was rebuffed. It seemed entirely fitting to use Old Amsterdam cheese on the cover, since much of Pierson’s PhD research had been conducted at the NKI (Netherlands Cancer Institute) in the Dutch capital. Pierson even explained to the cheesemakers that his project had to do with cutting slices off biological cells, just as one slices cheese with the typically Dutch cheese slicer known as a ‘kaasschaaf’. “Biological cells and cheese are very different things,” the cheese company decided and thus turned down Pierson’s request. Undeterred, he then bought some cheese, removed the Old Amsterdam’s typical black rind, made some slices and set up his cover’s still life. “I hope they can’t sue me for that,” he adds in jest.
Pierson developed a method for using a diamond knife to slice a deep frozen cell into 10 to 20 0.1 micron thin slices and then transferring the slices in an orderly manner to the grid of an electron microscope for imaging. The technique has been sold to Leica for use in their new microtomes.
