Research Bits: Feb. 28


Single-molecule switch An international team of researchers have demonstrated a switch on a single fullerene molecule. Using a laser, the team switched the path of an incoming electron. “What we’ve managed to do here is control the way a molecule directs the path of an incoming electron using a very short pulse of red laser light,” said Project Researcher Hirofumi Yanagisawa from the Uni... » read more

How To Build Resilience Into Chips


Disaggregating chips into specialized processors, memories, and architectures is becoming necessary for continued improvements in performance and power, but it's also contributing to unusual and often unpredictable errors in hardware that are extremely difficult to find. The sources of those errors can include anything from timing errors in a particular sequence, to gaps in bonds between chi... » read more
