Growth Signaling: TSC Takes Its Place

The protein products of the tumor suppressor genes tuberous sclerosis complex 1 and 2 form a protein complex, TSC1-TSC2, that inhibits growth. Several new studies suggest that TSC1-TSC2 does this by inhibiting TOR and S6 kinase, and that PI 3-kinase-Akt signaling relieves this inhibition.

Mass Transfer Within the Location Where Micro Electroplating Takes Place

The eukaryotic tree of life: endosymbiosis takes its TOL.

Resolving the structure of the eukaryotic tree of life remains one of the most important and challenging tasks facing biologists. The notion of six eukaryotic 'supergroups' has recently gained some acceptance, and several papers in 2007 suggest that resolution of higher taxonomic levels is possible. However, in organisms that acquired photosynthesis via secondary (i.e. eukaryote-eukaryote) endo...

A Stochastic Competitive R&D Race Where "Winner Takes All"

The paper considers an environment in which multiple firms compete over the development of a product. The first firm to complete the project gains a reward whereas the other firms gain nothing. The decisions of the firms are the level of investment in the project and these decisions affect the random (exponential) completion time. The paper provides a method for explicitly computing a unique Na...

REVI EWS SPACE AN D PlACE , HASTE AN D WASTE

space sprung from violence, and is political and institutional. I n the process, Lefebvre fi lls in the glaring hole of Marx's project b y supplying a dialectical material analysis of urban space. In so doing he converts Marx's "land" to "space. • Furthennore, he considers space to have an exchange value. Thus, space becomes a force of production. I t usurps the role originally played by nature...
