Researchers create prosthetic hand that offers more lifelike dexterity

Researchers at Georgia Tech have developed a prosthetic hand inspired by the bionic one given to Star Wars' Luke Skywalker. What sets this one apart from other prosthetics is the amount of dexterity it offers, allowing users to move individual finger...

Researchers use electric currents to detect cancer in human tissue

In a study published recently in Angewandte Chemie, researchers demonstrated that an imaging technique called scanning electrochemical microscopy could become a very useful medical tool. Rather than having to use additional chemicals like dyes or flu...

MIT researchers made a living ink that responds to its surroundings

Researchers at MIT have developed a 3D printable hydrogel that can sense and respond to stimuli. The hydrogel is loaded with bacteria that can be genetically programmed to light-up when they come in contact with certain chemicals and, therefore, coul...

Researchers 3D-print WiFi-connected objects that don’t need power

Researchers at the University of Washington have developed a way for 3D-printed plastic objects to transmit information via WiFi without the help of batteries or electronics. And they show that it can be done with commercially available plastics and...
