Quasiparticles do the twist
One of the most memorable lessons of an undergraduate course in quantum mechanics is that identical particles can have two types of “statistics.” An exchange of two identical bosons leaves the many-particle wave function unchanged, while an exchange of two identical fermions introduces a minus sign. The consequences of this minus sign are profound in all areas of physics. Moreover, it has long ...
متن کاملFlagellar microtubules do the twist
Pericentrin pivotal in primary cilia he centrosome protein pericentrin acts as an anchor for primary cilia formation in human cells, according to a report by Jurczyk et al. (page 637). The finding further unites the centrosome and primary cilia, both of which are based around centri-oles, and both of which use pericentrin as an anchor for other proteins. The authors show that pericentrin is loc...
متن کاملBacterial Sporulation: FtsZ Rings Do the Twist
Formation of the polar Z ring is a crucial step in the establishment of cellular asymmetry during sporulation of Bacillus subtilis. New results suggest that the transition from medial to polar Z rings involves a dynamic FtsZ spiral structure that may transfer FtsZ from medial to polar sites.

متن کاملContorted polycyclic aromatics.
CONSPECTUS: This Account describes a body of research in the design, synthesis, and assembly of molecular materials made from strained polycyclic aromatic molecules. The strain in the molecular subunits severely distorts the aromatic molecules away from planarity. We coined the term "contorted aromatics" to describe this class of molecules. Using these molecules, we demonstrate that the curved ...
