Hong Kong scientists found that ultrathin diamond sheets can generate electricity when bent, revealing a hidden piezoelectric effect

Researchers have identified a piezoelectric effect in ultrathin diamond membranes. This effect, previously unseen in bulk diamond, appears in thin polycrystalline sheets. Grain boundaries within these membranes are responsible for generating electrical responses when deformed. The strongest piezoelectric response was observed in membranes approximately five micrometres thick. This discovery opens doors for new applications in…

In 1990, John and Karen Lewis bought 1,000 acres of Costa Rican rainforest to stop it being logged; the reserve now shelters monkeys, sloths and over 300 bird species

John and Karen Lewis bought Costa Rica’s Osa Peninsula rainforest in 1990. They built a lodge and school, benefiting local residents and wildlife. The reserve became a vital buffer for Corcovado National Park. In 2013, a conservation easement ensured permanent protection for the land. This project demonstrates successful long-term private conservation efforts.
