Rare-earth elements that are crucial for clean-energy technologies are jealously fought over. Policies and programmes to encourage recycling and recovery could reduce tensions.
Origami — the art of making various shapes from a single piece of paper — has been realized at the nanoscale using DNA. Sheets of ‘DNA wireframe paper’ have been developed that, through folding along crease lines, can be transformed into a range of target shapes in response to external stimuli.
