It Consumer-Friendly?", R.C. (Swamy) Anantheswaran,
Pennsylvania State University. State University of New York at
Buffalo’s National Center for Case Study Teaching
This case introduces students to
consumer perceptions and beliefs on scientific topics, and teaches
them how the food industry evaluates processing technologies from
a business perspective.
This case is appropriate for
undergraduate food science/technology and business/management
Hamburger". Graham Peaslee, Hope College, Juliette Lantz,
Siena College, and Mary M. Walczak, St. Olaf College. State
University of New York at Buffalo’s National Center for Case Study
In this dilemma case study, in which a
restaurant chain must decide whether to use irradiated beef to
protect its customers from E. coli, students are introduced to
nuclear applications aside from those involving nuclear power
generation and weapons
This case is appropriate for
undergraduate physics and physical chemistry courses.
Brain: A Case Study of Seizure Disorder and Brain Function".
Julia Omarzu, Loras College. State University of New York
at Buffalo’s National Center for Case Study Teaching.
This case study involves a couple
deciding whether or not their son should undergo brain surgery to
treat a severe seizure disorder. In examining this dilemma,
students apply knowledge of brain anatomy and function. They also
learn about brain scanning techniques and discuss the plasticity
of the brain.
The case was written for an introductory psychology course, but
could be adapted for any course that covers brain anatomy,
neurological disorders, or rehabilitation therapies.
A Systems-level View of a Pregnancy with Medical Complications"
Y. Lorentzen, New Jersey Center for Science, Technology &
Mathematics Education, Kean University, and Youssef Kousa, College of
Osteopathic Medicine & Biochemistry and Molecular Biology
Department, Michigan State University
This case study follows a
woman faced with a series of difficult medical
apply systems-level physiology as they explore a
pregnancy with medical complications and discuss
situations involving life-changing decisions
prompted by modern medical technologies.
This case could be
used in an advanced biology course at the high
school level, or in undergraduate courses in general
biology, human anatomy and physiology, human health,
human sexuality, medical ethics, sociology, or

"Insect Robots": Biology 8th Ed. CNN Ed 2004 (2:46)
Bob Full is interested in
cockroach movement, specifically the ability of these insects to
move quickly over various surfaces and obstacles. His computer
studies have shown that insects move three legs at a time. Using
this information, he and other scientists have developed
six-legged robots that move about independently at speeds of up to
three meters per second. Despite the lack of any sensory system or
brain, one of the robots shown can navigate over or through
obstacles. Such robots may one day be used to explore the surfaces
of other planets or to locate land mines. Professor Full is also
studying the ability of geckos to cling to surfaces and would like
to make a robot with similar abilities. The worksheet includes the
URL for Professor Full’s website, which describes his ongoing
projects. (Student worksheet provided on CD)
of Artificial Hearts": Biology 5th Ed. CNN Ed 2001 (2:25)
The history of artificial hearts
is reviewed, with video of the 1969 implantation of the first such
device by Denton Cooley and the Jarvik 7 used on Barney Clarke in
1982. The drawbacks of these devices led researchers to turn
toward devices that are not designed to replace the heart but
rather to assist a failing ventricle. The most recent
product, the fully implantable AbioCor artificial heart, is shown
and its function is described. The worksheet includes the URL for
AbioMed, the company that manufacturers and is currently testing
the AbioCor heart. (Student worksheet provided on CD)
for Back Pain": Biology 5th Ed. CNN Ed 2001 (1:47)
A man who suffers from chronic
lower back pain is interviewed. He is receiving a relatively
new treatment: injections of “botox” or botulinum toxin A.
At high doses, this bacterial toxin causes muscle weakness and
botulism poisoning. However, when injected at low doses,
botox lessens pain by decreasing input from sensory fibers to the
spinal cord. A small (31 patient) clinical study, reported
in the journal Neurology, showed that botox injections reduced
chronic back pain for up to 8 weeks, without any apparent side
effects. The worksheet includes the URL for the online version of
Neurology, where an abstract of the study is available. (Student

Hand Transplant": Biology 5th Ed. CNN Ed 2001 (2:39)
A surgical team in Louisville has
transplanted a forearm and hand from a brain-dead patient to a
Michigan man who had lost his in a 1996 firecracker
accident. Animation shows the basic steps in the procedure,
which took 13 hours and required a team of 18 surgeons. In a
pre-surgery interview, the transplant recipient, who will require
physical therapy and lifelong immunosuppressive medication,
describes his reasons for undergoing the procedure. Earlier
hand transplant attempts and outcomes are briefly described.

"The Trials of an Artificial Heart"
Ditlea, Steve. Current Issues in Biology. Scientific
American, Inc. July 2002. 42-53.
This article gives a brief overview of the history of
the artificial heart and some current issues being faced
today. The articles focuses on the Abiocor, an artificial
heart that began clinical trials in 2001. This article
is followed by a short quiz and critical thinking questions.
