A 3D-printed “meta-bot” developed by UCLA engineers is capable of propulsion, movement, sensing and decision-making. It is manufactured all at once by a new type of 3D printing process for engineered active materials with multiple functions (also known as metamaterials). (Source: Rayne Research Group/UCLA)

How to Print a Robot in a Single Step

A team of UCLA engineers and their colleagues have developed a new design strategy and 3D printing technique to build robots in one single step. A study that outlined the advance, along with the construction and demonstration of an assortment of tiny robots that walk, maneuver and jump, was published in Science.

New research from Chalmers University of Technology and the University of Freiburg shows that wounds on cultured skin cells heal three times faster when stimulated with electric current. The project was recently granted more funding so the research can get one step closer to the market and the benefit of patients. (Source: Science Brush/ Hassan A. Tahini)

How Electricity Can Heal Wounds Three Times as Fast

Chronic wounds are a major health problem for diabetic patients and the elderly — in extreme cases they can even lead to amputation. Using electric stimulation, researchers in a project at Chalmers University of Technology, Sweden, and the University of Freiburg, Germany, have developed a method that speeds up the healing process, making wounds heal three times faster.
