- 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.

Low-cost cooling could help Bangladesh garment workers
A University of Sydney study, published in The Lancet Planetary Health on Monday (20 October), tested simple low-cost cooling in a chamber that mimicked extreme factory heat. Fans and water partly restored productivity; a reflective roof cut indoor temperature by 2.5°C.
