The proof-of-concept study, conducted by researchers at North Carolina State University, uses finely ground eggshells directly in the production of magnesium alloys through a process known as friction stir extrusion. The approach allows calcium-containing materials needed to improve magnesium’s mechanical properties to be produced during the manufacturing process itself, rather than being separately processed from mined ore before being added to the alloy.

Lawrence Livermore National Laboratory researcher Isaiah Santistevan led the development of three-dimensional simulations exploring how a nuclear device could deflect or disrupt an asteroid threatening Earth.
