3 scientists — 2 American, 1 British — won the 2019 Nobel Prize in medicine for studying how cells sense and react to varying oxygen levels, per AP.
Why it matters: The Nobel Committee said the scientists' work has "greatly expanded our knowledge of how physiological response makes life possible" and kickstarted new strategies to fight anemia, cancer and other diseases.
