To copy the way a desert beetle gets water, scientists have designed a membrane that can extract water from the air. Since all air contains water, even in the desert, this could provide a very inexpensive way to supply drinking water. This process is called “biomimicry,” or using ideas from nature to solve technological problems. This discovery could lead to reusable water bottles that refill themselves. Listen to learn why this invention would be inexpensive and how close scientists are coming to making it work.

Until recently, few people knew that the American space program’s early success was due in large part to a group of African American women known as “human computers.” They were brilliant mathematicians but were made to use segregated offices, bathrooms, and equipment. Their stories are told in a book and movie by the same name, “Hidden Figures.” One such overlooked mathematician was Katherine Johnson, who began working at Langley in 1953. Her report laying out trajectory equations for getting a craft into orbit played a key role in the program’s success. However, despite the vital roles Katherine and her colleagues held, their contributions were mostly unheard of until the publication of “Hidden Figures.” Listen to learn more about the obstacles these African American women faced and how a story this significant stayed buried for decades.
