NASA OSIRIS-REx mission and sample analysis on Asteroid BennuOn September 24, 2023, NASA's OSIRIS-REx mission successfully returned a capsule to Earth containing material from asteroid Bennu. This marked the first time a U.S. mission delivered pristine asteroid samples and is the largest asteroid sample return to date. These samples, among the oldest, most primitive, and pristine materials available, originate from a well-studied asteroid. They offer a unique opportunity to deepen our understanding of the formation and evolution of the solar system. In this talk, I will provide a brief overview of NASA's OSIRIS-REx mission and present our latest findings on the major and trace elemental composition, as well as the isotopes of moderately volatile elements, in Bennu samples.

6,000 Years of Indigenous Land Use,
Fire Management, and Colonial Impacts
in the Southwestern Amazon Rainforest Ecotone
The southwestern Amazon Rainforest Ecotone (ARE), a transitional zone bridging the tropical forest and seasonally flooded savannahs of Bolivia’s Llanos de Moxos, is distinguished by its biodiversity and long-standing records of human occupation and plant domestication. Although Indigenous environmental legacies are well-documented across much of Amazonia, their specific influence within the ARE’s ecological dynamics remains less understood. This study draws on 6,000 years of archaeological and paleoecological data from Laguna Versalles (LV) and Laguna Ignacito (LI) to reconstruct Indigenous land use practices and assess the environmental impacts of colonial interactions in the region.
This research integrates archaeological, paleoecological, and anthropological evidence to contextualize Indigenous land-use strategies within broader environmental shifts and colonial histories. The findings contribute to our understanding of long-term human impacts on forest ecologies and underscore the role of historical land management in shaping current environmental and socio-economic landscapes. These insights highlight the value of cross-disciplinary approaches in addressing the enduring environmental challenges of the Anthropocene.

Understanding Central European Volcanism: new age, chemical and petrological data, and the connection between Alpine foreland tectonics, magmatism, and hydrothermal activityThe Central European Volcanic Province (CEVP) comprises hundreds of Cretaceous to modern volcanoes of basaltic, basanitic, nephelinitic, melilititic, and evolved compositions. New data show surprising correlations between age, whole-rock composition, and mineralogy in SW German volcanics between Frankfurt, Basel and Konstanz, which record different melting episodes in a heterogeneous mantle. These are related to specific stages in Alpine foreland tectonics and even correlate with hydrothermal activity responsible e.g., for the formation of base metal deposits in the crystalline basement of the Schwarzwald. The talk will cover all these topics and present a broad overview of these exciting new results.
