SUMMARY:Reducing the problem: Photochemical Pathways in Prebiotic Chemistr
 y on Early Earth - Theresa Drobnik (Cavendish)
DTSTART:20260203T120000Z

CONTACT:Dr Dolev Bashi
DESCRIPTION:Understanding how life began on Earth is a major scientific ch
 allenge with direct relevance to the study of exoplanets. As part of the o
 rigin-of-life research\, scientists have identified chemical networks that
  could have produced life’s building blocks under early Earth conditions
 . One promising set of reactions\, known as cyanosulfidic chemistry\, can 
 efficiently make these molecules from simple starting materials abundant o
 n early Earth. However\, these reactions differ from modern biochemistry\,
  leaving a key question: How did early Earth chemistry evolve into modern 
 biochemistry?\nIn this talk\, I will introduce the origins of life researc
 h and briefly discuss its connections to the exoplanet community. I will t
 hen present our experimental work exploring whether ultraviolet (UV) light
  from the young Sun could help bridge the gap from geochemistry to biochem
 istry\, offering new insights into prebiotic chemical pathways. This talk 
 does not assume prior knowledge of origin-of-life research.
