This year marks the 100th anniversary of Haldan Keffer Hartline's graduation from the Bloomsburg State Normal School, the forerunner of present-day Bloomsburg University. Keffer's parents were both teachers. His father, Dr. Daniel S. Hartline, was a professor and biology department chair from 1897-1935 and his mother Harriet Keffer Hartline, served on the biology faculty. The Hartline Science Center at Bloomsburg University is named in honor of the Hartline family.  After graduating from the “college prep program” at the State Normal School in 1920, H. Keffer Hartline went on to Lafayette College, Johns Hopkins Medical School, and eventually to a position at the Rockefeller Institute in New York City.  Hartline investigated the very nature of vision—how photoreceptors of the retina convert light stimuli into electrical signals that are conducted along a neural pathway to the brain. His colleague Floyd Ratliff stated that “Hartline’s basic studies on the integrative action of the retina provided the foundation for practically every advance in the neurophysiology of vision.”  In 1967,  Haldan Keffer Hartline shared the Nobel prize in physiology or medicine with George Wald and Ragnar Granit for their work on elucidating the mechanisms of vision.  

To celebrate the 100th year anniversary of Dr. Hartline's graduation from Bloomsburg, the BU chapter of the Society of Physics Students hosted a symposium in reflect on Dr. Hartline's work, vision, and legacy.  Presenting at the symposium were BAHS professors Dr. Thomas Klinger, Dr. John Hranitz, and Dr. Clay Corbin. 

But what is more, if we have succeeded in adding to the basic understanding of our universe and ourselves, we will have made a contribution to the totality of human culture.

Internship Experience for Medical Imaging Majors

Image
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 ...

Heather Detwiler studies abroad in Australia

Image
Heather Detwiler , a B.S. Health Sciences major in the pre-accelerated nursing major, received a BU Professional Experience Grant to study abroad in Australia during the summer through at program at the University of Canberra.  She conducted research on the prevalence of concussions in youth populations in conjunction with the Australia Institute of Sport. Her work focused on the treatment and prevention of concussions in youth soccer players, a field that has not received much attention. Concussions are associated with long-term neurocognitive impairment. Australia has a higher prevalence rate for concussions among youth soccer players, perhaps since heading the ball during games and practices is allowed.  Heather's study compared the differences between youth soccer concussion treatment and prevention methods between Australia and the United States. During her stay in Australia, Heather had the opportunity to travel, visiting Melbourne, The Great Ocean Road, Canberra, Sydney...
