Tapping into underground urban heat islands
Cities are heat islands – not only above ground but below ground too, and therein lies the enormous potential to better harness this energy through geothermal heat exchangers. A group of researchers demonstrated this in a case study conducted in the city of Zurich.
Tiny organisms with a massive impact
Although diatoms are incredibly small, they have a significant impact on the dispersal of nutrients and trace elements in global marine waters. This is the conclusion of a study recently published in the scientific journal “Nature Geoscience
