Honeybees somehow manage to efficiently collect a lot of nectar with limited resources and no central command - after all, the queen bee is too busy laying eggs to oversee something as mundane as where the best nectar can be found on any given morning. According to new research from the Georgia Institute of Technology, the swarm intelligence of these amazingly organized bees can also be used to improve the efficiency of Internet servers faced with similar challenges.

In the growing catalog of nanoscale technologies, nanowires - tiny rows of conductor or semiconductor atoms - have attracted a great deal of interest for their potential to build unique atomic-scale electronics. But before you can buy some at your local Nano Depot, manufacturers will need efficient, reliable methods to build them in quantity.
