A materials scientist's dream come true

Materials can deform plastically by atomic-scale line defects called dislocations. Many technical applications are based on this fundamental process, such as forging, but we also rely on the power of dislocations in our everyday life: in the crumple zone of cars dislocations protect lives by transforming energy into plastic deformation. Researchers have now found a way of manipulating individual dislocations directly on the atomic scale.

Stern of World War II US destroyer discovered off remote Alaskan island

In the midst of World War II on August 18, 1943, the USS Abner Read struck what was presumed to be a Japanese mine in the Bering Sea. The catastrophic blast took the lives of 71 American sailors. For their families, the final resting place of loved ones lost remained unknown. Until now. On July 16, 2018, a team of researchers using robotics technology discovered the sunken stern of the World War II destroyer — solving a 75-year-old mystery.
