The future of clean energy is hot. Temperatures hit 800 Celsius in parts of solar energy plants and advanced nuclear reactors. Finding materials that can stand that type of heat is tough. So experts look to Mark Messner for answers. A principal mechanical engineer at the U.S. Department of Energy's (DOE) Argonne National Laboratory, Messner is among a group of engineers who are discovering better ways to predict how materials will behave under high temperatures and pressures.

A new take on artificial intelligence may open many doors for 3D printing and designing advanced nuclear reactors. The future of clean energy is hot.

CAMBRIDGE, MASSACHUSETTS – Has your child swallowed a small battery? In the future, a tiny robot made from pig gut could capture and expel it. Researchers at the Massachusetts Institute of Technology are designing an ingestible robot that could be used to patch wounds, deliver medicine or dislodge a foreign object. They call their experiment an "origami robot" because the accordion-shaped gadget gets folded up and frozen into an ice capsule. "You swallow the robot, and when it gets to your stomach the ice melts and the robot unfolds," said Daniela Rus, a professor who directs MIT's Computer Science and Artificial Intelligence Laboratory.
