Geoscientists gradually decipher nature's playbook, discover new mineral-making secrets



Sugars are widely known as important sources of energy for all organisms.

Now, Virginia Tech researchers have discovered that certain types of sugars, known as polysaccharides, may also control the timing and placement of minerals that animals use to produce hard structures such as shells and exoskeletons of mollusks, lobsters, and shrimp.

Writing in the Proceedings of the National Academy of Sciences, Anthony Giuffre of Delafield, Wisc., a graduate student in the Department of Geosciences, and his research advisor, Patricia Dove, a University Distinguished Professor in the College of Science, propose a theory of how charged and uncharged sugars can be used to create shells and skeletons.
