Traditional computer chips run on electricity, while the emerging photonic chips use light. Now, scientists at Harvard have demonstrated a new kind of chip that transmits data in the form of sound waves. Computer chips and circuits send and process data by modulating a particular medium. Most of the time that medium is electrons, the…

As far as data security is concerned, there is an even greater danger than remote cyberattacks: namely tampering with hardware that can be used to read out information — such as credit card data from a card reader. Researchers in Bochum have developed a new method to detect such manipulations. They monitor the systems with…
