Y. Zhou et al., "The mammalian Golgi regulates numb signaling in asymmetric cell division by releasing ACBD3 during mitosis," Cell, 129:163-78, Apr. 6, 2007. This excellent paper reports a novel means of coupling cell-cycle progression with cell fate decisions. The authors show that the fragmentation of the Golgi complex, which precedes mitosis of neural progenitor cells, releases a Numb binding protein, thereby modulating cell fate decisions fol

C.A. Feillet et al., "Lack of food anticipation in Per2 mutant mice," Curr Biol, 16:2016-22, Oct. 24, 2006. The two period genes, Per1 and Per2, are integral parts of biological rhythm generation in the body's master clock, housed in the hypothalamic suprachiasmatic nuclei. The authors show now that the absence of Per2 expression abolishes the centrally regulated anticipation of meal times without interfering with the entrainment of peripheral clocks by nu

Some data have shown, not quite conclusively, that the major histocompatibility complex profile of a man plays some role in the type of woman he attracts. Women prefer non-matching MHC profiles, sometimes, but not all the time. These preferences haven't been followed up much in those aspects that go beyond simple mate choice. A newly published study in linkurl:__Psychological Science__;http://www.blackwellpublishing.com/journal.asp?ref=0956-7976&site=1 looked at 48 couples in long-term relatio

In 1973, the Cohen-Boyer team introduced a plasmid fragment from one strain of Escherichia coli, conferring kanamycin resistance in
