For the 150th anniversary of the periodic table, we asked our scientists about their favourite element

Dr. Sebastian Teichert, Chair of Palaeontology, on magnesium:

“My favorite element is magnesium (Mg), which can be found in numerous minerals. Even my main research object, the coralline red algae, incorporate it into their calcite skeleton – namely in dependence of the environmental conditions. Furthermore, as they develop an annual rhythm such as trees, I can, for example, indicate earlier temperatures or the advancing ocean acidification with the help of the magnesium concentration – exactly to the year and partly more than 100 years back in the past. To collect the respective sample material from the ocean floor of the Arctic Zone, my work area, is a special pleasure, of course.”
