- Scientists study recycling of old batteries now.
- They want to recover valuable metals from these batteries.
- The new method uses safe water-based chemical solutions.
- The reactions are very fast at room temperature.
- It is faster and uses much less energy.
- Water lowers thickness and helps molecules move faster.
- Researchers turned the recovered metals into new batteries.
- The method may be easier for factories to scale up.

The Philippine government has opened renewable energy projects to more foreign investment while authorities have intensified "red‑tagging" of activists. Local NGOs that deliver disaster relief and clean technology say they have been targeted, hindering aid work.
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.
Father’s microplastic exposure affects offspring health
A mouse study found that when fathers were exposed to microplastics, their offspring developed metabolic problems. Female offspring showed diabetic signs and researchers linked the effect to changes in sperm small RNAs; the work was published in the Journal of the Endocrine Society.
