- Mangroves grow on tropical and subtropical coasts.
- Saltwater often covers their roots and soil.
- Scientists study how they survive salt.
- Mangroves often have very small leaf cells.
- Their cell walls are thicker than usual.
- Small cells and thick walls give strength.
- This helps stop leaves from wilting in floods.
- These traits appear in many different lineages.
- Researchers hope the ideas can help other plants.
- The work aims to make crops more tolerant.

Light controls a calcium-powered protein engine for artificial cells
Researchers adapted a ciliate calcium-pulse strategy to make a protein network that contracts when calcium is released by light. The light-controlled system can repeat cycles, move tiny particles and may help synthetic drug delivery.
