Each spring, animals move from their winter grazing grounds in search of greener pastures. For birds, where and when to start that journey is based on genetics, and signals from stars, and magnetic fields from the earth. But for some larger mammals like sheep and moose, they’re not born knowing where to go. They need to learn a mental migratory map—and it’s often passed down from other herd members. Ecologists Matthew Kauffman and Brett Jesmer join Ira to tell us more.

Plus: Employers tend to design offices and other workspaces to maximize productivity and minimize costs—hence the rise of the open office plan. But a recent study of two large companies published in Philosophical Transactions of the Royal Society B found that open office plans reduced face-to-face contact and productivity, a counterintuitive effect. What else is changing work-life balance into an imbalance? Researchers Ethan Bernstein, Nancy Rothbard, and Sarah Andrea discuss the changing science of work.
