University of Sheffield researchers have developed a new ultrasound method that could help to more easily diagnose abnormal tissue, scarring and cancer. A new ultrasound method that can measure the level of tension in human tissue for the first time – a key indicator of disease – has been developed by researchers from the University of Sheffield.

The breakthrough, made by Dr Artur Gower from the University’s Department of Mechanical Engineering, together with researchers from Harvard, Tsinghua University, and the University of Galway, could be used to build new ultrasound machines that are able to better diagnose abnormal tissue, scarring, and cancer.

Ultrasounds use sound waves to create images of organs inside the human body...

Carnegie Mellon University engineers have developed a soft material with metal-like conductivity and self-healing properties that is the first to maintain enough electrical adhesion to support digital electronics and motors. This advance, published in Nature Electronics, marks a breakthrough in softbotics and the fields of robotics, electronics, and medicine.

At Carnegie Mellon University, softbotics represents a new generation of soft machines and robots manufactured by multi-functional materials that have integrated sensing, actuation, and intelligence.

The research team introduced the material, a liquid-metal filled organogel composite...

In a historic achievement, University of Rochester researchers have created a superconducting material at both a temperature and pressure low enough for practical applications.

“With this material, the dawn of ambient superconductivity and applied technologies has arrived,” according to a team led by Ranga Dias, an assistant professor of mechanical engineering and physics...

As the evolution of standard microchips is coming to an end, scientists are looking for a revolution. The big challenges are to design chips that are more energy efficient and to design devices that combine memory and logic (memristors). Materials scientists from the University of Groningen, the Netherlands, describe in two papers how complex oxides can be used to create very energy-efficient magneto-electric spin-orbit (MESO) devices and memristive devices with reduced dimensions.

The development of classic silicon-based computers is approaching its limits...
