Science Blog - Aged roaches experience perils of stiff joints

Science Blog: "'Insects provide a useful model for aging studies because they're short-lived compared with mammals,' reports Ridgel.

Schaefer contributed to the paper with his look at the roach's escape behavior and how it changes during the aging process. He also reported in the paper that roaches had lacked the spontaneous response to flee from a predator in lab studies, but this escape behavior returned after the roach's head was removed, suggesting a deficiency in the brain.

'There is also irony and humour in my objects as well as a criticism of the way animals are treated by society.'"
