New sediment archive for historical climate research
Geological investigations of low-temperature young deposits on the Styrian Erzberg provide paleoclimatology with new data on the earth's history and its development. Additional at the end of the text How has the climate changed in the course of the earth's history? Which climatic processes have influenced the earth and its atmosphere? Paleoclimatology seeks answers to such questions in order to better understand climate changes and to derive forecasts for future climate scenarios.

Mineral undergoes self-healing of irradiation damage
Mineral undergoes self-healing of irradiation damage
Several minerals suffer radioactive self-irradiation and hence experience long-term changes of their properties. The mineral monazite virtually behaves "just alike Camembert cheese in which holes are drilled": Existing radiation damage heals itself. An international research team led by Lutz Nasdala, Institute of Mineralogy and Crystallography, University of Vienna, conducted an ion-irradiation study that has unravelled the causes of the self-healing of monazite.

Giant teenage shark from the Dinosaur-era
Giant teenage shark from the Dinosaur-era
Fossil vertebrae give insights into growth and extinction of an enigmatic shark group Scientists of the University of Vienna examined parts of a vertebral column, which was found in northern Spain in 1996, and assigned it to the extinct shark group Ptychodontidae. In contrast to teeth, shark vertebrae bear biological information, like body size, growth, and age and allowed the team surrounding Patrick L. Jambura to gain new insights into the biology of this mysterious shark group.
