Three studies find that a family of organic compounds affects the formation and initial growth of atmospheric aerosol particles in clean air — with implications for our knowledge of the climate ...

Analysis of organic compounds -- called polycyclic aromatic hydrocarbons (PAHs) -- extracted from the Ryugu asteroid and Murchison meteorite has found that certain PAHs likely formed in the cold areas ...

Chemists studying how life started often focus on how modern biopolymers like peptides and nucleic acids contributed, but modern biopolymers don't form easily without help from living organisms. A ...

An instrument on the Perseverance rover has identified large, complex carbon compounds alongside unusual patterns on the surface of rocks that resemble traces of microbial activity ...

Compound libraries form a foundational element of modern drug discovery—the process of identifying new chemical or biological compounds that can become safe and effective medicines. Compound libraries ...
