Researchers from Princeton and MIT have found a way to intercept underwater messages from the air, overturning long held assumptions about the security of underwater transmissions. The team created a device that uses radar to eavesdrop on underwater acoustic signals by decoding the tiny vibrations those signals create on the water’s surface. The technique could also roughly identify the location of an underwater transmitter. In the paper, the researchers detail the technology and offer ways to guard against the attakcs it enables.
Researchers have used artificial intelligence (AI) to analyse patient urine samples and predict when symptoms of chronic obstructive pulmonary disease (COPD) will flare up according to a study published today (Wednesday) in ERJ Open Research. This could make it possible to take steps, such as altering treatment, to minimise or even prevent a flare up.
