Acoustic tweezers move objects in the body remotely

Researchers at the University of Washington and Moscow State University demonstrated the technique by trapping 3-mm glass beads in vortex-shaped beams of ultrasound. By steering the beams electronically, or by simply moving the ultrasound transducer, they directed the beads along complex 3D paths within a water tank and in the bladders of live pigs.

Cosmonaut builds engineered cartilage aboard the International Space Station

For the first time, 3D human tissue has been assembled in the microgravity of space. Through a magnetic levitation device, researchers in Russia, led by Vladislav Parfenov at the Russian Academy of Sciences and 3D Bioprinting Solutions, enabled a cosmonaut aboard the International Space Station (ISS) to fabricate human cartilage from a few isolated cells.
