Ultrasound can propagate through solid surfaces and activate voice recognition systems, allowing the person who initiates the attack to also hear the phone's response. Out of 17 different phone models tested, 15 were vulnerable to ultrasonic wave attacks.
A new technology known as sonogenetics can control neural activity by using sound frequencies. The technology could be used to non-invasively treat a range of neurological conditions, including Parkinson's disease and epilepsy.
Using transcranial focused ultrasound in combination with injectable microbubbles, researchers open a pathway through the blood-brain barrier. The technique allows drugs to penetrate the brain and trigger therapeutic effects for those with neurodegenerative diseases.
A study of macaque monkeys reveals low-intensity ultrasound can both generate and suppress signalling in the brain and modulate normal function. The ultrasonic stimulation alters counterfactual thinking, allowing the ability to decide upon a better alternative in decision-making tasks.
