Protein-based drugs can quickly lose activity during transport and storage. To prolong the proteins’ activity, drug firms add stabilizers, including polyethylene glycol and trehalose, a disaccharide that some organisms use to protect themselves from dehydration.

Now Heather D. Maynard and her research team at the University of California, Los Angeles, have combined the two molecules to create trehalose glycopolymers . . .
