Hydrogen sulfide, recognized by its characteristic rotten egg smell, is synthesized in the respiratory center -- an integral brain region governing respiration. Researchers have identified that hydrogen sulfide within the respiratory center plays a crucial role in maintaining the rhythm and depth of respiration by modulating neurotransmissions.

A technology developed over the past few years for controlling microvehicles using ultrasound also works in the brain, as researchers have now been able to show. These microvehicles are gas bubbles, which are harmless and dissolve once their job is done. In the future, these microvehicles could be equipped with medications and deliver them to specific points in the brain. This may increase the efficacy of the drugs and reduce their side effects.

Engineers have developed a bio-compatible ink that solidifies into different 3D shapes and structures by absorbing ultrasound waves. Because the material responds to sound waves rather than light, the ink can be used in deep tissues for biomedical purposes ranging from bone healing to heart valve repair.
