What happened

Light-controlled molecular switches offer exciting possibilities for future electronics, data storage Lisa Lock Scientific Editor Alexander Pol Deputy Editor Whether it's neurons responding to electrical signals or plants stretching toward light, nature is…

Why it matters

Now, researchers want to develop new responsive materials for a wide range of applications, such as sensing or low-energy technologies.

Common ground

However, achieving a balance of useful properties at the molecular level is challenging.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
