A light-Controlled Flexible Lens may Give Soft Machines Vision

Healthcare, Medicine / Jorge Paka

Inspired by the human eye, our biomedical engineering team at Georgia Tech has developed an adaptive lens made from soft, light-sensitive materials. Traditional adjustable cameras rely on bulky, rigid lenses and a pupil to control focus and brightness. In contrast, the human eye achieves this through soft, flexible tissues in a compact design. A Soft,

Magnetic Gel May Offer a more Efficient Way To Eliminate Kidney Stones

Healthcare, Medicine / Ana Kiesse Zeleme

Stanford University has introduced a ureteroscopy-friendly device that uses a wire to magnetically capture and remove kidney stone fragments, demonstrating superior results compared to conventional methods in a pig model. Kidney stone disease impacts roughly 11% of people in the U.S. and frequently necessitates ureteroscopic laser lithotripsy. Removing fragments after lithotripsy is often inefficient, leaving
