Have you ever wondered if there may be a way to identify noise-induced damage before hearing loss occurs?
If so, you may want to check out this study by Parham and colleagues (2018). In 2018, these researchers studied the levels of prestin (a protein found specifically in outer hair cells) in the blood of mice after being exposed to noise. This study revealed that the levels of prestin rose sharply when outer hair cells were damaged and start to die. The authors discuss the implications of these findings and next steps for studying the phenomena in humans.

When you present one tone to one ear and a second to the other ear, your brain perceives an additional tone. This is the essence of binaural beats.

Who’s Afraid of Snakes?
Research shows that approximately half of the population feel “anxious” about snakes, and a whopping three percent of the population meet the diagnostic criteria for snake phobia (Polak et al., 2016). Is it their skin? Is it that they have no legs and thus slither? Is it the tongue? Is it their ears? Wait—do snakes…
