The similarities between a Van Gogh painting and a golf ball

On a molecular scale, there are surprising similarities between the outer shell of a golf ball and the white oil paint used by Van Gogh and his contemporaries. In both cases, the interactions between zinc ions and polymer ...

Sheaths drive powerful new artificial muscles

Over the last 15 years, researchers at The University of Texas at Dallas and their international colleagues have invented several types of strong, powerful artificial muscles using materials ranging from high-tech carbon ...

French scientists claim to have created metallic hydrogen

Scientists have long speculated that at the heart of a gas giant, the laws of material physics exhibit remarkable characteristics. In these kinds of extreme pressure environments, hydrogen gas is compressed to the point that ...

3-D printed tissues and organs without the scaffolding

Engineered tissues and organs have been grown with various degrees of success in labs for many years. Many of them have used a scaffolding approach where cells are seeded onto biodegradable supportive structures that provide ...

Artificial muscles powered by glucose

Artificial muscles made from polymers can now be powered by energy from glucose and oxygen, just like biological muscles. This advance may be a step on the way to implantable artificial muscles or autonomous microrobots powered ...
