Cyclic AMP signaling in Drosophila mushroom body neurons, anchored by the adenylyl cyclase encoded by the rutabaga gene, is indispensable for olfactory memory formation. From a screen for new memory mutants, we identified alleles of the gilgamesh (gish) gene, which encodes a casein kinase Iγ homolog that is preferentially expressed in the mushroom body neurons. The gish-encoded kinase participa...

Arecibo high-resolution radar images of the southern hemisphere of Venus extending to 78 degrees S show that the surface of the Themis-Alpha-Lada region is characterized by linear deformation zones with volcanoes and corona-like features and by regional volcanic deposits (primarily plains, small shields, and large edifices). Large-scale areal deformation is limited to the tessera of Alpha Regio...

There is a long history of stories about events that threaten the end world or life after major catastrophe. The Naxi Annals Creation and Mesopotamian Gilgamesh Epic tell floods all but on Earth. H.G. Well’s 1897 story, War Worlds, Martians invading Earth, who themselves are killed by terrestrial epidemic. 1954 Japanese film, ゴジラ (Godzilla), marine reptile mutated nuclear radiation attacks huma...
