Elizabeth Culotta and Shraddha Chakradhar, both Deputy News Editors, explore the influential impact of colonial legacies on modern science, emphasizing the shift towards inclusivity in research methodologies, especially in the Global South. They discuss efforts to integrate local voices and perspectives into scientific practices. Mario Fischer-Gödde, a research scientist, dives into the origins of the Chicxulub asteroid, revealing insights about its unique geologic signatures and the implications for our understanding of Earth's history and potential asteroid resources.
The new series emphasizes how researchers in the Global South are addressing colonial legacies in scientific practices through inclusive collaboration.
Research on the Chicxulub impactor sheds light on asteroid origins, enhancing our understanding of cosmic events and their impact history.

Innovative Postbiotic Research
Research into postbiotic gut microbiota metabolites is gaining traction as a potential solution for metabolic and immune-related diseases. Companies like Noster are pioneering this field by developing products such as biosynthesized GMP bacteria preparations and the world's first HYA-50 metabolite postbiotics healthcare supplement. These innovations are set to revolutionize healthcare by utilizing the body's microbiome, promoting better health outcomes. Analytical services offered, including liquid chromatography and mass spectroscopy, allow for advanced gut microbiota analysis, further supporting the effectiveness of these products.
Confronting Colonial Legacies in Science
A new series aims to highlight how researchers, especially in the global South, are addressing the lingering effects of colonialism in scientific practices. The introduction discusses how the historical context of colonialism still influences modern science, particularly through practices like parachute paleontology, where scientists extract fossils from previously colonized countries without local engagement. Examples show significant participation from local authors in recent publications, indicating a shift towards more inclusive scientific collaboration. The series will explore these themes further, showcasing models of success in overcoming the colonial legacy.
Asteroid Impact Research and Its Implications
A study examined the origins of the Chicxulub impactor, which is believed to have led to the dinosaurs' extinction, providing insights into asteroid formations in our solar system. This research strengthens the hypothesis that the Chicxulub impactor was likely an asteroid, while highlighting the significance of detecting platinum group elements in the geological signature left by the impact. Over time, different impact structures have revealed distinct isotopic signatures that suggest varying sources from the inner and outer solar system. Future applications could involve analyzing lunar samples to trace impact history, enhancing our understanding of these cosmic events.
First up this week, Deputy News Editors Elizabeth Culotta and Shraddha Chakradhar join host Sarah Crespi to talk about the launch of a new series highlighting the latest in postcolonial science. They cover how researchers around the world, but especially in the Global South, are reckoning with colonial legacies and what is in store for the rest of the series.
Next, producer Meagan Cantwell talks with Mario Fischer-Gödde, a research scientist at the University of Cologne about the origins of the giant asteroid thought to have killed off the dinosaurs 66 million years ago.
