Could this be the end of bifocals? Researchers have devised a pair of specs that use flexible lenses and piezoelectric pistons to automatically adjust focus on the fly, shifting the lenses' curvature as the user gazes at objects near or far. The glasses are programmed by inputting the user's prescription through a phone app. Then a microcontroller uses info from a built-in sensor that measures the distance to the desired focal point.

Researchers have devised a way to measure dopamine in the brain much more precisely than previously possible, which should allow scientists to gain insight into dopamine's roles in learning, memory, and emotion. Read more at MIT News.
A new approach has been found to boosting the lifetime and effectiveness of electronic biomedical devices. The discovery will help the devices better communicate with neural tissue by improving adhesion. Read more at University of Delaware News.
U.S. researchers have taken a major step toward the use of frozen or cryopreserved tissues and organs for transplantation, an advance that may one day ease the shortage of available organs, experts said on Tuesday. Read more at Reuters.
Researchers have now found that physical forces exerted between cancer cells and the ECM are enough to drive a shape change necessary for metastasis. Those forces converge on an optimal stiffness that allows cancer cells to spread. Read more from the Wistar Institute.
Ultra-flexible, nanoelectronic thread (NET) brain probes have been designed that can achieve more reliable long-term neural recording than existing probes and don't elicit scar formation when implanted. These smaller-than-a-capillary-sized probes could provide the reliable brain interface needed to control prosthetics, or follow the progression of neurodegenerative diseases.

The cutting-edge biocompatible near-infrared 3-D tracking system used to guide the suturing in the first smart tissue autonomous robot (STAR) surgery has the potential to improve manual and robot-assisted surgery and interventions through unobstructed 3-D visibility and enhanced accuracy, according to a new study.
