The Norwegian research organisation SINTEF will investigate whether rare earth element minerals contribute to pollution in costal areas.
The Norwegian research organisation SINTEF will investigate whether rare earth element minerals contribute to pollution in costal areas. Research scientists from Norway, Denmark and Germany are taking part in the project.
The rare earth elements (REEs) are also referred to as the ‘black gold’ of the 21st century. They constitute key metals utilised in high-tech technologies and are crucial if we are to achieve a greener and more efficient industrial sector and implement the green transition.
Medicines, electric vehicles, mobile phones, wind turbines, fuel additives and fertilisers, as well as other high-tech industries, all make use of REEs such as scandium and gadolinium. But can their use also be harmful to life in our fjords and oceans, our environment and the food we eat? Does the way we use REEs make it inevitable that they w

As climate change increases average global temperatures and creates more extreme heatwaves, researchers worry that not all organisms can still adapt and survive.
A study led by the Department of Biology at the Norwegian University of Science and Technology (NTNU) has spent four years studying zebrafish (Danio rerio), a species of tropical fish, and how it adapts to warmer climates, especially extremely warm periods. It looks like evolution is slower than global warming in this case, says associate Fredrik Jutfelt from NTNU, who also serves as the senior author in the study. Their findings are published in the Proceedings of the National Academy of Science (PNAS), December 14, with Dr. Rachael Morgan - now with the University of Glasgow - as the lead author.

The climate is changing, and heatwaves are becoming more common and intense as a result. For the Great Barrier Reef, the world’s largest structure of living tissue, the consequences are clear. The reef suffered its third mass coral bleaching event in five years in 2020, caused by prolonged periods with high water temperatures. Conservation scientists recently downgraded the ecosystem’s condition to “critical”.
You might expect mobile animals like fish to fare better, but their body temperatures closely match that of the surrounding water. Fish can of course swim and escape high temperatures to an extent – and many species have shifted their ranges poleward or into deeper, cooler waters. But migration isn’t always possible. Freshwater fish, for instance, are restricted to their native rivers or lakes. Their ability to adapt to high temperatures may decide whether or not they endure.
