Is science getting closer to identifying ways to reverse hearing loss from damaged hair cells?
This article discusses recent findings from the research team at the Johns Hopkins School of Medicine in Baltimore, Maryland, who investigated cochlear hair cell differentiation in mice during development.
The identification of two proteins, Activin A and follistatin, in this study may lead to innovative treatment options for hearing loss in the future. This article provides an overview of how these proteins contribute to cochlear hair cell development, and the implications this may have for future treatments of sensorineural hearing loss.

Lack of Physical Activity and Obesity in Individuals with Self-Identified Hearing and/or Visual Difficulties
It is reasonable that lack of physical activity would be one thing associated with obesity, but could difficulties hearing and/or seeing also be a factor influencing that relationship? What about gender? Pardhan and colleagues (2021) used data collected from the 2017 Spanish National Health Survey to evaluate the relationship between physical inactivity and obesity by…
Do you remember why Joseph Sauveur is important to our profession? If you do, you could have done better than a recent contestant on the legendary gameshow, Jeopardy. The question posed was: “Born hearing-impaired in 1653, Joseph Sauveur studied sound vibrations and coined this word for the science he pioneered.” While I was impressed that…
Sudden sensorineural hearing loss (SSNHL) can occur with or without symptoms of vertigo/vestibular dysfunction. In a recent study, investigators sought to determine the contribution of audiogram classification when evaluating vestibular dysfunction in those with SSNHL. A total of 50 subjects who had experienced SSNHL were divided into two groups, one without vertiginous symptoms and one…
