A USC Stem Cell study found that the mammalian outer ear evolved from cartilaginous gills in fishes and marine invertebrates. The research used gene control elements to show a connection between gill and ear development.
Researchers found that specific auricular acupuncture improved the recovery rate for depression to 58%, compared to 43% for non-specific treatment. The study also showed no severe adverse effects, with most participants reporting mild pain at the needle application site.
Researchers from IOCB Prague and MED-EL have created a complete computer model of the ear, allowing for detailed simulation of sound conversion and hearing processes. This model may help improve cochlear implants and better compensate hearing impairments.
The MedSENS instrument measures body temperature, heart rate, and oxygen saturation from the ear canal using innovative sensors. It has been tested in harsh environments and proven to be easy to use, with its data transmitted wirelessly to other devices.
Scientists have discovered a master gene that programs ear hair cells into either outer or inner ones, enabling the development of these cells to restore hearing. This breakthrough could provide a previously unavailable tool to create specific hair cells and improve treatments for age-related hearing loss.
A research team from TUM discovered that birds use their oval-shaped heads to transform sound waves, allowing them to identify sounds from different elevation angles. This unique ability combines information from hearing and vision to improve orientation and evading predators.
