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...

Survival in acute and severe low o environment: use of a genetic model system.

29 Sep 2009 Hypoxia whether present during physiologic states (e.g., embryogenesis) or during pathologic states (e.g., obstructive sleep apnea and sickle cell anemia), challenges the vertebrate or invertebrate organism. Clearly, hypoxia can lead to sublethal ... Read more...

The cell adhesion molecules Echinoid and Friend of Echinoid coordinate cell adhesion and cell signaling to regulate the fidelity of ommatidial rotation in the Drosophila eye.

29 Sep 2009 Directed cellular movements are a universal feature of morphogenesis in multicellular organisms. Differential adhesion between the stationary and motile cells promotes these cellular movements to effect spatial patterning of cells. A prominent ... Read more...
