A study published December 9 in the journal Physical Review E details the similarities between the trajectory of sea urchin sperm and computer systems that use a type of real-time search approach called extremum seeking. Engineers from the University of California, Irvine and University of Michigan made a mathematical model of the sperm’s pathway to better understand its behavior. According to the authors, assessing the sea urchin’s biological nature could help design miniature robots that follow cues from sources in the same way. Read More
