Whether a volcanic eruption is violent with high dust emissions, or quiet depends, among other things, on the composition of the melt (molten rock) which then forms the lava. It also depends on additional factors such as whether magma comes into contact with water on its way, says geologist Professor Ewa Słaby, director of the Institute of Geological Sciences of the Polish Academy of Sciences and president of the European Mineralogical Union.
Carrion beetles from the species Necrodes littoralis, commonly known as shore sexton beetles, cover the corpse with a heat-generating coating. This provides favourable conditions for the development of their offspring, Polish scientists have shown. In the future, this research could allow forensic scientists to more accurately determine the time of death.
