B.P. Tu et al., ?Logic of the yeast metabolic cycle: temporal compartmentalization of cellular processes,? Science, 310:1152?8, Nov. 18, 2005.

Cells grown in continuous and nutrient-limited conditions exhibit periodic metabolic cycles accompanied by a synchronized expression of most of their genes in three consecutive waves. This temporal compartmentalization might optimize key metabolic and cell-cycle processes and could be the origin of circadian and ultradian oscillators.

R.C. Albertson et al., ?Integration and evolution of the cichlid mandible: The molecular basis of alternate feeding strategies,? Proc Natl Acad Sci, 102:16287?92, Nov. 8, 2005.?

This paper combines genetic and developmental data to implicate bmp4 (bone morphogenetic protein 4) as a key locus in the evolution of jaw morphology in cichlid fish. ? It suggests that bmp4 might be of general importance in the evolution of vertebrate head diversity.
