Veterans are approximately 30% more likely than non-veterans to suffer from severe hearing impairment. Tinnitus, or ringing in the ears, which is increasingly common among military service men and women, has been linked to significant cognitive and psychological impairment and can be worsened by the same sounds that trigger post-traumatic stress disorder (PTSD). In fact, tinnitus and PTSD often present as comorbidities, and recent studies suggest these two disorders may share a common neurological pathway. Additional studies are required to better understand the connection between hearing loss and impaired cognitive function such as that observed in with PTSD. Here, we use the fruit fly, Drosophila melanogaster, to explore the relationship between hearing loss and cognitive function. Negative geotaxis climbing assays and courtship behavior analysis were used to examine neurobehavioral changes induced by prolonged, intense auditory stimulation. Preliminary results suggest that exposure to loud noise for an extended period of time significantly affected Drosophila behavior, with males being more sensitive than females. Based on our results, there appears to be a potential connection between noise exposure and behavior, further suggesting that Drosophila could be an effective model to study the link between hearing loss and PTSD.

Socioeconomic differences have driven society and laid the foundation for the types of opportunities and resources one is eligible to receive. Higher socioeconomic status provides individuals the chance of obtaining an overall better education, occupation, and income. We see this with particular clarity when we examine healthcare. The World Health Organization has regarded healthcare as a fundamental human right, except socioeconomically disadvantaged individuals not only do not have equal access to healthcare, but they also often receive a lower quality of care. These socioeconomic differences are often paired with racial differences, resulting in one group, or set of groups, having social advantage over the others. Although this problem has been discussed throughout the past century, it has not been properly addressed materially and practically. Unequal access to quality healthcare is especially highlighted throughout the COVID-19 pandemic, where there has been evidence that minorities, in particular Black communities, have received inadequate care. Quality healthcare has become unaffordable and a luxury that only certain groups get the privilege of receiving. Not only that, but the ongoing inequalities in the healthcare system have gone so far that they have instilled hostility and mistrust towards the healthcare system.

The COVID-19 pandemic places significant strain on the U.S. healthcare system due to the high number of coronavirus cases. During the pandemic, there was much unknown about the virus, its course of the disease, COVID-19 diagnosis, treatments, or other imperative information needed to contain the virus. Resources within the healthcare system, such as PPE and healthcare workers, were in short supply and exacerbated the difficulty of managing the viral outbreak. Peer-reviewed articles suggest that telehealth, the application of electronic information and telecommunication technologies in healthcare, proved useful in public health and clinical care during the 2020 public health emergency due to a novel virus. The scoping review broadly assessed themes of telehealth’s strengths and weaknesses during the COVID-19 pandemic. These findings could suggest how virtual medicine may be a helpful tool to improve access in addition to the quality of care in the future of medicine. Assessments of case studies suggest that telehealth helped provide care to large patient volumes by aiding with communication, data collection, triage, remote patient monitoring, and critical care. Limitations of expanding telehealth subsequent to the pandemic include, but not limited to, a lack of national standards for practice and restrictions of utility for certain populations. Populations may include those with low socioeconomic status, specific cultural practices, and beliefs, or physical and cognitive ability barriers. Outlining the benefits and limitations of telehealth may suggest how virtual medicine can provide valuable in day-to-day medical practices and other pathogenic outbreaks.

Communication skills are vital for the world we inhabit. Both oral and written communication are some of the most sought-after skills in the job market today; this holds true in science, technology, engineering and mathematics (STEM) fields. Despite the high demand for communication skills, communication classes are not required for some STEM majors (Missingham, 2006). STEM major maps are often so packed with core classes that they nearly exclude the possibility of taking communication courses. Students and job seekers are told they need to be able to communicate to succeed but are not given any information or support in developing their skills. Scientific inquiry and discovery cannot be limited to only those that understand high-level jargon and have a Ph.D. in a subject. STEM majors and graduates must be able to translate information to communities beyond other experts. If they cannot communicate the impact of their research and discoveries, who is going to listen to them?<br/>Overall, the literature around communication in STEM fields demonstrate the need for and value of specific, teachable communication skills. This paper will examine the impact of a communication training module that teaches specific communication skills to BIO 182: General Biology II students. The communication training module is an online module that teaches students the basics of oral communication. The impact of the module will be examined through the observation of students’ presentations.
