The soft hair under a goat’s neck is the key source of expensive cashmere fibers. Yak and sheep manes, which are much less valuable, are sometimes blended or exchanged with cashmere. To verify fabric labels, textile manufacturers usually rely on fiber surface analyses done with light microscopy or scanning electron microscopy. But those methods can be time-consuming and subjective. Now, a team in Italy has developed a proteomics strategy to identify the species from which . . .
