Cockroaches can skitter through a crowded under-the-sink cabinet, eluding capture or worse, making the insects a model for rescue robots that would creep through the debris of disaster in search of survivors.
But learning how they use all six legs at the same time to walk, run and turn has been a difficult and time-consuming task. Until now.
Using a pair of high-speed cameras and a custom computer program, researchers at Case Western Reserve University are able to simultaneously extract three-dimensional movement of a cockroach’s 26 leg joints. They report their findings in the online journal PLoS ONE.
“Each leg does something a little different but in concert,” said John Bender, a postdoctoral research associate in the department of biology and lead author of the study. A cockroach doesn’t inch ahead on the push of one leg. So, to understand just one step requires a synchronous picture of what each joint in each leg is doing as the insect is propelled forward.
Bender, biology professor Roy Ritzmann and undergraduate researcher Elaine Simpson, who has since graduated, used synchronized digital high-speed cameras to produce 3-D images of the leg joints of a moving cockroach. The cameras shoot 500 frames per second for 8 seconds.
Bender led development of software that enabled them to analyze in hours 106,496 individual 3-D points, with about 90 percent accuracy. He estimated that to analyze the 3-D movement of all 26 joints frame-by-frame would take at least a couple of weeks. Read more.
Just as pumpkin pie is part of the Thanksgiving tradition, the Election Night Party hosted by Case Western Reserve University Department of Political Science, the Case Republicans, the Case Democrats, and Alexander Lamis’ Midterm Election class, is traditional November fare.

During this week full-time faculty who were hired before April 2010 will receive an invitation from Provost Bud Baeslack to participate in the Faculty Climate Survey. The survey is a follow-up to the 2007 faculty survey and is designed to help the university learn more about faculty members’ assessment of the quality of the academic community. A subset of questions will also be asked of students and staff in separate surveys. Results will allow comparison of how each campus constituency perceives the environment for inclusion and diversity. Questions about the survey can be directed to the Office of Institutional Research at email@example.com.

For two sequential UCITE sessions, Sarah de Swart (from UCITE) will discuss some of the central elements that go into making good presentations. The first session will cover important points such as voice and body language, and the second will give participants a chance to try out their skills on a presentation of their own. Being able to give good presentations is an important skill. Apart from simply being a way to influence how other people view you, preparing a good presentation helps to sharpen one's ideas, be more concise and pointed in one's message, and improve one's awareness of the power of language to persuade. Part one of this discussion is at noon Thursday in the Herrick Room on the ground floor of the Allen building (at Adelbert and Euclid). Pizza lunch and sodas will be provided at the sessions. To help us estimate the amount to order, please let us know if you plan to attend each session by email. More information is available online.
