Glass specialist Claudine Loisel studies the chemistry of stained glass on a nanoscopic scale. Here, she examines a panel that survived the fire at Notre‑Dame cathedral in Paris last year, checking it for damage. The protective gear guards her against possible exposure to lead in the metal framework that holds the shards of glass in place. “I’m part of an amazing team of historians, conservators and materials specialists working to restore, protect and eventually reopen Notre-Dame,” she says. “After that, we’ll have a glass of champagne.” (Nature | 2 min read) (Francois Mori/AP/Shutterstock)
