Power/Performance Bits: July 10


Wearable heart monitoring Researchers at the University of Texas at Austin developed a lightweight, stretchy heart monitoring patch that can be worn externally. Along with being easy to wear, the graphene-based 'e-tattoo' is more accurate than existing electrocardiograph machines, according to the team. The e-tattoo measures cardiac health using both electrocardiograph and seismocardiograph... » read more

When Cryptographers Disagree


Six of the world's leading cryptography experts sat down this week to explore the most pressing issues in security. They took up topics ranging from whether Apple should facilitate the FBI's access to a known terrorist's iPhone, to what will become the next important cryptography algorithm. Among them: Ronald Rivest, an Institute Professor at MIT; Adi Shamir, co-inventor of the RSA algorithm... » read more

System Bits: Feb. 23


Making electrons act like liquid While electrical resistance is a simple concept in that rather like friction slowing down an object rolling on a surface, resistance slows the flow of electrons through a conductive material, and now, MIT professor of physics Leonid Levitov and Gregory Falkovich, a professor at Israel’s Weizmann Institute of Science have found that electrons can sometimes tur... » read more
