Skeletons in the Closet
Breakthroughs in microscopy technology provide new insights into cell biology. Early microscopes allowed Robert Hooke to see cells. Improved staining techniques enabled Camillo Golgi to see the apparatus that bears his name, and Robert Feulgen to visualize DNA in chromosomes. Similarly, EM allowed Keith Porter to visualize the endomembrane system. More recently, transgenic technology using fluo...
متن کاملThe Nodal Closet
The synthesis of this text comes from a contemporary appraisal of the term “the closet” and its current place in culture since the advent of cybernetics. The authors’ assertion is that this metaphor, one that is rooted in the iconography of the late-capitalist home, is in a moment of transition and constant redefinition. In this paper, the authors explore and assess three basic modern manifesta...
متن کاملMorgenbesser cases and closet determinism
(MC1) Chump tosses an indeterministic coin and, whilst it is in midair, calls heads. The coin lands tails, and Chump loses. His betting was causally independent of the coin’s fall. Chump seems right to say: ‘If I had bet tails, I would have won.’1 (MC2) Champ narrowly misses a plane which subsequently crashes due to unexpected indeterministic events. His missing the plane was causally independe...
متن کاملSkeletons from the Treecode Closet
We consider treecodes (N-body programs which use a tree data structure) from the standpoint of their worst-case behavior. That is, we derive upper bounds on the largest possible errors that are introduced into a calculation by use of various multipole acceptability criteria (MAC). We find that the conventional Barnes-Hut MAC can introduce potentially unbounded errors unless < 1=p3, and that thi...
متن کاملAnother Cytoskeleton in the Closet
Many eukaryotic cells contain up to three families of cytoskeletal proteins that are responsible for the spatial organization of the cell. Although the prokaryotic origins of the actin and tubulin families have now been established, the origin of the third was unknown. In this issue of Cell, provide evidence that the third family, comprising the intermediate filaments, also has origins in bacte...
