Astronomers use the term dark energy to refer to energy in the universe that is unaccounted for by ordinary matter but necessary to explain cosmology. Astronomy, however, isn't the only field with missing energy. Rice University professor Peter Wolynes and postdoctoral researcher Carlos Bueno, along with Universidad de Buenos Aires collaborators Ezequiel Gaplern, Ignacio Sánchez and Diego Ferreiro, recently published a paper describing the "dark energy" found in the structural protein universe. This missing energy comes from the tension between the form of a protein and its function.
