Science: Graduate students who study biological physics now have their own international network to help them advance their careers. The Physics of Living Systems Student Research Network (PoLS-SRN) is hosted by the center for theoretical biophysics at the University of California, San Diego, and includes 28 participating institutions from North and South America, Europe, and Asia. Biological physics is a relatively young, interdisciplinary field that lacks the career networks that form naturally when several “generations” of researchers spread out and establish laboratories. One goal of PoLS-SRN is to introduce theorists and experimenters who work on the same problems.
