Dr. Greg Byrnes (Siena College, Loudonville, NY) and Dr. Bruce Jayne (University of Cincinnati, OH) discovered that snakes use more force than is necessary to support their weight when climbing. To climb, snakes rely on friction and repeatedly contract and extend their bodies, a process called concertina locomotion. To study the forces generated by snakes during this type of locomotion, the researchers constructed a vertical cylinder that was covered with textured tennis racket tape…
jhalper | September 18, 2011Our latest annual report is now online, and we think the results are worth looking at. We started with a favorite theme -- art and science -- and took it a step further. Ten short pieces on scientific research that deals with movement -- of proteins, electrons, black holes or theoretical random walkers -- are paired with works of art on a similar theme. Then we added poetry and fiction written by scientists, for good measure.

The feeling that you willed your arm into motion, and the realisation that you moved it at all, are both the result of an area at the back of your brain called the posterior parietal cortex.
