World’s first wireless molecular network uses rubbing alcohol to send text messages

World’s first wireless molecular network uses rubbing alcohol to send text messages

Researchers in the UK and Canada have succeeded in creating the world’s first text message via a molecular communication. The messages are encoded in molecules of alcohol, which are then wafted across the room to a receiver, which sniffs the molecules out of the air and decodes the message. Molecular networks are an area of interest for applications and environments ...

Researchers crack the world’s toughest encryption by listening to the tiny sounds made by your computer’s CPU

Researchers crack the world’s toughest encryption by listening to the tiny sounds made by your computer’s CPU

Security researchers have successfully broken one of the most secure encryption algorithms, 4096-bit RSA, by listening – yes, with a microphone — to a computer as it decrypts some encrypted data. The attack is fairly simple and can be carried out with rudimentary hardware. The repercussions for the average computer user are minimal, but if you’re a secret agent, power user, ...

The world’s most smallest FM radio transmitter – made from graphene

The heart of every radio transmitter is a reliable oscillator. Creating small, and tunable, oscillators that can maintain a precise frequency when conditions like temperature, pressure or humidity change, can be challenging. Engineers from Columbia University have just revealed to us the world’s smallest FM transmitter, which they managed to build around a nanoscale graphene oscillator. Details of their device ...
