Control Of Molecular Switches Increased By Tailored Intermolecular Interactions - SpaceDaily   A means to stabilize molecular switches based on chemical interactions with surrounding molecules has been developed by a research team led by Penn State Professor of Chemistry and Physics Paul S. Weiss. "The chemical interactions that we observed reduce random switching, which could decrease the refresh rate needed for a random-access-memory device, and significantly reduce power usage." Weiss points out that this research is providing basic information about the mechanism of switching, and that its application in computers is not imminent. "By engineering tailored intermolecular interactions into our molecular designs, we have introduced control to electronic switching of single molecules," says Weiss. The research is an essential step toward molecular engineering of computer components at the nanoscale.
Neo-Tugboats: The No-Nukes Option? - SpaceDaily  Left: One concern about nuclear explosions on incoming asteroids is the 'buckshot effect' that one rock splits into a wider damage area. Image Credit: David Hardy  From current missions underway to others awaiting critical funding, to future proposals, a wealth of knowledge will soon be produced regarding the structural characteristics of these bodies. My concern reflects, of course, my own preference for the B612 "gentle push" methodology for asteroid deflection. But this concern in fact applies to virtually all of the "soft" deflection techniques, e.g., mirror deflection, laser deflection, and the direct push recommended by B612.    

After Trio Of Explosions, Scientists Say Supernova Is Imminent - SpaceDaily  Three powerful recent blasts from three wholly different regions in space have left scientists scrambling. The blasts, which lasted only a few seconds, might be early alert systems for star explosions called supernovae, which could start appearing any day. The first two blasts, called X-ray flashes, occurred on September 12 and 16. These were followed by a more powerful burst on September 24. The burst seems to be on the cusp between an X-ray flash and a full-fledged gamma ray burst, a discovery interesting in its own right.
