- Materials Science
Mussel glue inspires coating for medical implants
An antifouling coating inspired by the sticky adhesive secreted by mussels could protect future medical implants from failure.
- Materials Science
Glass materials let Venetian art shine
Sixteenth-century Venetian painters mixed glassy materials with their paints to expand their palettes and enhance the vibrancy of their colors.
- Materials Science
Bonelike polymer supports stem cells
A polymer scaffold that mimics the environment in which natural bone grows provides stem cells with the right cues to lay down new bone.
- Materials Science
