BAHS students present research at the Pennsylvania Academy of Science Meeting

The 91st Annual Meeting of the Pennsylvania Academy of Science was held on April 11 at Lebanon Valley College. Jacob Morton, Blake Shoemaker and Drs. Surmacz and Hranitz presented a poster on their research on the "Effects of Temperature on the Levels of Heat Shock Protein 70 in Blackworms (Lumbriculus variegatus)." The aim of this research is to determine if blackworms can be used as bioindicators to assess the health of aquatic ecosystems. Blackworms are good candidates because they are sensitive to a variety of environmental toxins and display easily measured physiological responses to stress.  Jake and Blake's research investigated the physical properties, physiological and behavioral changes, and cellular stress responses in a population of cold-adapted worms in order to establish a control for comparison. Dr. Surmacz also presented a talk on "Vision and Change in the Biology Classroom:  Meet the Life Science Teaching Resource Community."

Internship Experience for Medical Imaging Majors

BAHS medical imaging majors gained valuable experience with various imaging technologies  during internships at Geisinger Health System.   Intern Ashley Wilkins  reports: "I  have been able to see so much in the Radiology field. I have observed general diagnostic radiology, MRI, CAT scan, and ultrasound. I have seen x-rays of different body parts, especially of the chest. I have also seen numerous MRIs of the brain and spine and CAT scans of the chest and abdomen. Lastly, I have seen many pregnancy ultrasounds. My favorite part of the internship is being able to start learning early. I definitely recommend this internship to other students. It is a great way to become more familiar with the type of environment you will work in during your career. It is also  a jump start to your learning, because you get to see so much and you have the opportunity to ask questions. " Intern Xiang Liao states .  "I learned how to position patients, collimate light fields, locate cen
