Get Ready for an Inspiring Lineup!

Mark your calendars for September 11th at 8 AM PDT / 11 AM EDT! Prepare to dive deep into the fascinating world of geosciences at the highly anticipated 2025 LIFE NASA RCN Seminar Series.

Meet the Experts!

This month's seminar features two leading figures in the field: Prof. Jennifer Macalady and Dr. Alta Howells, each bringing unique insights into our planet's mysteries.

Discover Microbial Wonders!

Prof. Jennifer Macalady, esteemed professor at Pennsylvania State University and director of the International Geobiology Course, will take center stage with her talk on "Microbial Pyrite Production." Her cutting-edge research explores the intricate interplay between life and Earth materials, from sunlit soils to the depths of subsurface caves. Using innovative tools in microbial ecology and geochemistry, she examines crucial cycles of carbon, iron, and sulfur, revealing how these elements have evolved over Earth's history and their impact on our climate today.

Unraveling the Mysteries of Methanogenesis!

Following her, Dr. Alta Howells will present on "Methanogenesis at Dissolved Inorganic Carbon Extremes: How CO2 Availability Shapes Methanogen Physiology." This talk promises to shed light on how varying levels of carbon dioxide influence the physiology of organisms that generate methane, a critical component of our ecological balance.
