Anyone who s seen an old cartoon or film about mining knows the image of a sooty man making his way through a dark tunnel. When his lantern lights upon a brilliant diamond or a hunk of gold, he hacks away at the rock until the precious mineral is free.
In today s world, of course, it s a lot more complicated than that. Minerals hosting important metals like cobalt, copper, uranium and vanadium are thoroughly embedded in less valuable rock, and extracting the metals requires knowing the properties of the minerals and surrounding rock, as well as a long list of tools and processes. As the world moves toward sustainable technologies ranging from solar panels and windmills to electric vehicles, mining the material to build these technologies is more important than ever. ....

WEST LAFAYETTE, Ind. Autonomous underwater vehicles have become versatile tools for exploring the seas. But they can be disruptive to the environment or have trouble traveling through confined spaces.
Purdue University researchers are studying an alternative: highly maneuverable, low-cost underwater gliders that operate silently. Components and sensors of the glider also can be easily swapped out or added according to a wide range of mission specifications. ....

Polished glass has been at the center of imaging systems for centuries. Their precise curvature enables lenses to focus light and produce sharp images, whether the object in view is a single cell, the page of a book, or a far-off galaxy.
Changing focus to see clearly at all these scales typically requires physically moving a lens, by tilting, sliding, or otherwise shifting the lens, usually with the help of mechanical parts that add to the bulk of microscopes and telescopes. ....
