The second modern synthesis of biology [1] must start with new stratifications and conceptualizations, as well as new ways to connect all of them [2], which are to be perfected through in-depth discussions that may be provoked by seemingly controversial ideas. And new paradigms can thus be built upon the novel thoughts that may eventually converge. As knowledge accumulates based on either newly...
متن کاملBlood on the Tracks: Two Pathways for Predation
Accurate predatory behavior requires coordination between pursuit activity and prey consumption, yet the underlying neuronal circuits are unknown. A novel study published in this issue of Cell identifies two coordinated circuits emanating from the central amygdala that control the efficiency of prey capture and the ability to deliver fatal bites to prey.
متن کاملCancer genetics: Two tracks but one race?
The protein p16 was initially identified as an inhibitor of cyclin-dependent kinase (Cdk) activity — specifically, it was found to bind and inhibit cyclin D–Cdk4 [1]. This inhibition prevents phosphorylation of the retinoblastoma product (Rb) and progression from G1 to S phases of the cell cycle [2,3]. Previous observations that the Rb gene is frequently inactivated, and the cyclin D gene ampli...
متن کاملTrees on Tracks
Simultaneous embedding of planar graphs is related to the problems of graph thickness and geometric thickness. Techniques for simultaneous embedding of cycles have been used to show that the degree-4 graphs have geometric thickness at most two [3]. Simultaneous embedding techniques are also useful in visualization of graphs that evolve through time. The notion of simultaneous embedding is relat...
