A shape-shifting robot can access hard-to-reach locations in the GI tract, and is a step up from conventional endoscopic techniques.
Making edible pigments from photonic materials
Using a derivative of cellulose, researchers explore making a natural food colorant from materials whose surfaces manipulate light.
Using ice to make ultra-clean 2D materials
Using the adhesive properties of ice, researchers have developed a transfer method to move large sheets of 2D materials without breaking them.
4D printing “living” structures inspired by immortal jellyfish
4D printing produces a living polymer network that can be printed into 3D shapes and then broken down into its monomer units for reuse.
What are neuromorphic computers?
To make computers faster and more efficient, scientists are using the brain as a model in this blossoming area of computer science.
3D cell spheroid promotes spinal cord repair in mice
Stem-cell laden nanostructures prevented cell death while promoting growth and differentiation to help repair the spine following injury.
Flexible zinc-air batteries for wearable electronics
A novel hydrogel component could increase the life cycle of cheap, safe, environmentally friendly, and energy-efficient batteries.
