For a single supermassive black hole, extremely strong lensing occurs only when a star lies almost exactly along the line of ...
Researchers propose a new technique to identify supermassive black hole binaries through gravitational lensing causing ...
Researchers unveil octopus-inspired smart skin that hides images, changes shape, and encodes data via 4D printing.
The team used their new printing method to encode a photo of the Mona Lisa onto their smart skin material (left). The photo, which can initially appear hidden in the material, can be revealed by ...
Researchers at Penn State have developed a fabrication method that can print multifunctional “smart synthetic skin” — ...
