MIT engineers have developed a small ultrasound sticker that can monitor the stiffness of organs deep inside the body. The sticker, about the size of a postage stamp, can be worn on the skin and is designed to pick up on signs of disease, such as liver and kidney failure and the progression of solid […]
A new fusion of materials, each with special electrical properties, has all the components required for a unique type of superconductivity that could provide the basis for more robust quantum computing. The new combination of materials, created by a team led by researchers at Penn State, could also provide a platform to explore physical behaviors […]
Superhydrophobic surfaces, which repel water strongly, are useful for self-cleaning, anti-corrosion, and oil/water separation. Traditional methods to create these surfaces are complex and material-specific. Recent innovations include 3D printing for customizable surfaces and hydrothermal methods for durable coatings. A new approach using femtosecond laser and chemical treatments promises easier creation of these surfaces on various […]
See the comprehensive testing of Lego plastic vs carbon fiber vs aluminum vs stainless steel Lego-compatible axles in this video, evaluating their maximum torque, durability, and friction.
This video from Modern Goldsmith demonstrates how to extract pure gold from a raw mineral blob.
