Recent Examples on the Web When dried out, these teeny crustaceans will fill their cells with a sugar called trehalose that suspends molecules within a glassy matrix, preserving them like fossils in amber. 
Katherine J. Wu, Smithsonian, 10 Dec. 2019 Researchers believe this trehalose molecule not only replaces water, but also in some cases can physically constrain the critter's remaining water molecules, keeping them from rapidly expanding when faced with hot and cold temperatures. Daisy Hernandez, Popular Mechanics, 7 Aug. 2019 Their process uses pullulan, used in the food industry to extend the shelf life of food, and trehalose, a stabilizing agent. Kelsey Piper, Vox, 5 June 2019 To us, trehalose is an indistinguishable sweetener. Beth Mole, Ars Technica, 10 Jan. 2018 When the mice drank trehalose-laced water, RT027 killed nearly 80 percent of them. Beth Mole, Ars Technica, 10 Jan. 2018 Check the label for ingredients like brown sugar, corn sweetener, corn syrup, dextrose, fructose, glucose, high-fructose corn syrup, honey, invert sugar, lactose, malt syrup, maltose, molasses, raw sugar, sucrose, trehalose and/or turbinado sugar. Rebecca Drudi, baltimoresun.com, 10 Sep. 2017 Scientists previously believed that tardigrades survive desiccation by using a sugar called trehalose found in other creatures that can complete such a feat, including brine shrimp, yeast and tree frogs.
