Upside-down design expands wide-spectrum super-camera abilities

By turning a traditional lab-based fabrication process upside down, researchers at Duke University have greatly expanded the abilities of light-manipulating metasurfaces while also making them much more robust against the ...

Rocks unravel the secrets of the Earth's magnetic field

More than 350 million years ago something odd was going on with the Earth's magnetic field. Scientists now propose that the field was really weak, which may have affected life on our planet.

Shapeshifting microrobots can brush and floss teeth

A shapeshifting robotic microswarm may one day act as a toothbrush, rinse, and dental floss in one. The technology, developed by a multidisciplinary team at the University of Pennsylvania, is poised to offer a new and automated ...

Laser creates a miniature magnetosphere

Magnetic reconnections in laser-produced plasmas have been studied to understand microscopic electron dynamics, which is applicable to space and astrophysical phenomena. Osaka University researchers, in collaboration with ...
