For the first time, researchers have demonstrated a prototype device that can send unbreakable secret keys from a handheld device to a terminal.  But the potential introduction of ultra-powerful quantum computers renders our personal information vulnerable to direct attack.  When future users of quantum computers need to analyze their data or run quantum algorithms, they will often have to send encrypted information to the computer.  Quantum systems were believed to provide perfectly secure data transmission because until now, attempts to copy the transmitted information resulted in an altered or deteriorated version of the original information, thereby defeating the purpose of the initial hack.  Researchers have developed a new type of light-enhancing optical cavity that is only 200 nanometers tall and 100 nanometers across. Their new nanoscale system represents a step toward brighter single-photon sources, which could help propel quantum-based encryption and a truly secure and future-proofed network.  Researchers at Tohoku University have, for the first time, successfully demonstrated the basic operation of spintronics-based artificial intelligence.  The neural structure we use to store and process information in verbal working memory is more complex than previously understood, finds a new study by researchers at New York University.  Surviving breast cancer changed the course of Regina Barzilay's research. The experience showed her, in stark relief, that oncologists and their patients lack tools for data-driven decision making.  New research, led by the University of Southampton, has demonstrated that a nanoscale device, called a memristor, could be used to power artificial systems that can mimic the human brain.  Scientists at Helmholtz-Zentrum Dresden-Rossendorf conducted electricity through DNA-based nanowires by placing gold-plated nanoparticles on them. In this way it could become possible to develop circuits based on genetic material.
