Researchers from Georgia Tech, the University of Tokyo, and Microsoft Research have developed a technique in which cheap, functional electric circuits can be printed using only $300 of material and equipment. This technique uses silver nanoparticle ink instead of utilizing sintering. The researchers were able to print a circuit in roughly 60 seconds onto almost any material that can go through a printer, though some materials worked better than others.

A group of app developers, consumer advocates and others are agreeing to test a voluntary code of conduct for data privacy for mobile apps. The code would set requirements for participating developers to release notices regarding whether their apps collect certain types of personal information or share user specific data with third party groups or data resellers. The Obama administration favors consumer privacy laws, but has yet to release additional details. Continue reading Code of Conduct to Disclose What Data Mobile Apps Collect
