New study shows that Lake Mien was formed by a meteoric impact

Published 23 March 2021 Illustration: Pixabay. Volcano or meteorite? Over the past 100 years, two different theories have been put forward to explain the formation of Lake Mien. However, researchers from Lund University can now definitively state in a new study that the lake in Småland was formed by a gigantic celestial object. It was long thought that the circular Lake Mien in southern Småland wa

Birds' blood functions as heating system in winter

Published 16 April 2021 Coal tit. Photo: Andreas Nord. Researchers at Lund University in Sweden have discovered that bird blood produces more heat in winter, when it is colder, than in autumn. The secret lies in the energy factories of cells, the mitochondria. Mammals have no mitochondria in their red blood cells, but birds do, and according to the research team from Lund and Glasgow this means th
