After studying a nationally representative dataset of more than 10,000 households, University of Chile researchers have identified a link between increased household density and symptoms of depression in Latin America.

German and Danish physicists used an electric field to control the single atomic bond between a specialized microscope and a one-atom-thick layer of graphene. The newly realized approach, accomplished by changing the voltage across the bond, allowed the researchers to pick up and drop the graphene with the microscope like a crane.

Researchers from the Massachusetts Institute of Technology have designed the worlds first fiber with digital capabilities that can be incorporated into fabric. Capable of storing music, videos or other files in clothing, the thread can also collect physiological data from the wearer in order to analyze and predict their activity, potentially revolutionizing the personal health technology industry.
