- 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.

Molecule stores sunlight and releases heat on demand
Chemists at UC Santa Barbara designed a modified molecule called pyrimidone that captures sunlight, stores it in chemical bonds and releases it as heat when triggered. Tests released enough heat to boil water under normal conditions.
Jaw membrane in ancient Thrinaxodon may be an early eardrum
Researchers used CT scans and engineering simulations on a Thrinaxodon fossil. Their models show a membrane in the jaw could work as an eardrum, pushing the origin of sensitive mammal hearing back by nearly 50 million years.
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.
