Video: Swedish rare earth discovery calls attention to mining’s effects on Sámi reindeer herders
In January 2023, Swedish state-owned mining company LKAB announced that it had identified more than 1 million tonnes of rare earth oxides near the town of Kiruna in northern Sweden. Though mining this deposit may reduce reliance on China for rare earths, the impacts of a new mine on Kiruna residents and the indigenous Sámi people cannot be overlooked.

Read MoreSmall scale, big discoveries: Reducing thickness of antiferroelectric films turns them ferroelectric
While size effects in ferroelectric materials have been extensively studied, there are far fewer studies on how structure and properties evolve in antiferroelectric materials with reduced dimensions. In a recent open-access paper, researchers report the surprising discovery that below a certain thickness, antiferroelectric films will become completely ferroelectric.
