COVER This week's Focus Issue highlights the nucleus (see the Editorial Guide [http://stke.sciencemag.org/cgi/content/abstract/sigtrans;2007/415/eg11]). Articles and resources at STKE focus on signaling within the nucleus, as well as transport between the nucleus and the cytoplasm. The image depicts an artist's rendition of a cell nucleus.
