Track4-3 Scientists and designers at Cornell University in the United States are working on fashion’s next big thing: “wearable technology.” These clothes do many different things, and some already exist. For example, Juan Hinestroza, a scientist from Colombia, is making shirts, pants, dresses, and other clothing items. Some of these clothes warm or cool your body when the weather changes. Others change color and style. A third type never gets dirty. We can use less water, says Hinestroza, if we don’t wash clothes all the time. Other scientists and designers are working together to protect people from malaria. Frederick Ochanda, a scientist from Kenya, is making a special suit to stop malaria. The clothes have a chemical inside that stops mosquitoes. Matilda Ceesay, a clothing designer from Gambia, is working with Ochanda to make the suit fashionable. This is important, she says, because the clothes must look good or no one will buy and wear them. Scientists need to work with fashion designers so the clothes are both comfortable and stylish.
