- Scientists at a university study rubber with small particles.
- These particles make the rubber much stronger and stiffer.
- The team used many computer simulations to test ideas.
- Simulations showed how many atoms move inside the rubber.
- The rubber does not like to change its shape.
- Particles stop the rubber from thinning when stretched strongly.
- Because of that, the material becomes harder to stretch.
- The finding can help make safer, longer‑lasting products today.

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.
