Read moreInverse design: New route to design a practical invisibility cloak
Invisibility has become a scientific possibility with the emergence of metamaterials and transformation optics in the past few years. A recent paper reviewed design methodologies and experimental developments of the invisibility cloak from a practical perspective. The recent transition from a forward cloaking design to inverse cloaking design was also addressed.

Read moreNew nanotechnology therapeutics could soon fight influenza, other viruses
Newly emerging flu viruses could soon be countered by a treatment that Draper Laboratory is developing that 'traps' viruses before they can infect host cells. Further into the future, patients suffering from any type of virus could be cured with DRACO, a drug also under development at Draper that is designed to rapidly recognize and eliminate cells infected by virtually any virus.

Read moreResearchers find that computer components can be damaged by key manufacturing processes
During a recent experiment, a number of gold nanorods were irradiated with xenon atoms. They were a good subject for the experiment because nanowires or rods have a large surface area. The findings were dramatic. The scientists were hoping to generate bubbles. They actually found that they were eroding the nanowires.
