If you wanted to 3D print an object that was magnetic in some areas only, you'd typically have to print two separate items out of different metals, then join them together. A new take on an existing ...

Ultrasonic sound waves have been used to levitate objects in crowded rooms to make hologram-like displays. Such acoustic levitation was previously only practical in empty spaces, but a new algorithm ...

Researchers have mapped magnetic fields in three dimensions, a major step toward solving what they call the 'grand challenge' of revealing 3D magnetic configuration in magnetic materials. The work has ...

Physicists Prof. Dr. Ingo Rehberg from the University of Bayreuth and Dr. Peter Blümler from Johannes Gutenberg University Mainz have developed and experimentally validated an innovative approach for ...

A team of engineers at North Carolina State University has designed a polymer “Chinese lantern” that can rapidly snap into multiple stable 3D shapes—including a lantern, a spinning top, and more—by ...

Millirobots that can adapt to unstructured environments, operate in confined spaces, and interact with a diverse range of objects would be desirable for exploration and biomedical applications.
