A dynamic oral cancer field: unraveling the underlying biology and its clinical implication.

30 Oct 2009 Oral cancer is a complex disease that is characterized by histologic and genetic heterogeneity. The evolution and progression of this disease is thought to result from the accumulation of alterations in molecular pathways. Although the oral cavity ... Read more...

A stretch from the periphery helps brain clocks feel the daily heat.

27 Oct 2009 In this issue of Neuron, Sehadova et al. show that synchronization of circadian clocks in the brains of Drosophila by daily temperature changes requires chordotonal organs, mechanosensory structures that function as stretch receptors in insects. ... Read more...

The optogenetic catechism.

14 Oct 2009 An emerging set of methods enables an experimental dialogue with biological systems composed of many interacting cell types--in particular, with neural circuits in the brain. These methods are sometimes called "optogenetic" because they use ... Read more...
