MOON MOSAIC — A gorgeous image of the Moon from Noel Carboni via NASA: “No single exposure can easily capture faint stars along with the subtle colors of the Moon. But this dramatic composite view highlights both. The mosaic digitally stitches together fifteen carefully exposed high resolution images of a bright, gibbous Moon and a representative background star field. The fascinating color differences along the lunar surface are real, though highly exaggerated, corresponding to regions with different chemical compositions.” (NASA)
DARPA publishes all its open source code in one place
"Making our open source catalog available increases the number of experts who can help quickly develop relevant software for the government," Chris White, the DARPA program manager behind the effort, said in a statement. "Our hope is that the computer science community will test and evaluate elements of our software and afterward adopt them as either standalone offerings or as components of their products."
In science fiction, there’s no problem a good giant robot suit can’t solve. And yet, in reality, we all commute to work in dumb ol’ cars, fight our wars with boring guns, and make bland love with our decidedly non-mechanical genitals. Where are our mechs, science? Where are our god damn mechs?! Oh wait, here they are. Sorry about that, Science.
By coaxing light out of a single polymer molecule, researchers have made the world’s tiniest light-emitting diode.
This work is part of an interdisciplinary effort to make molecular scale electronic devices, which hold the potential for creating smaller but more powerful and energy-efficient computers. Guillaume Schull and his colleagues at the University of Strasbourg in France made the device with the conducting polymer polythiophene. They used a scanning tunneling microscope tip to locate and grab a single polythiophene molecule lying on a gold substrate. Then they pulled up the tip to suspend the molecule like a wire between the tip and the substrate.
The researchers report in the journalPhysical Review Letters that when they applied a voltage across the molecule, they were able to measure a nanoampere-scale current passing through it and to record light emitted from it.
