(Inside Science) — The 2019 Nobel Prize in physiology or medicine has been awarded to three scientists “for their discoveries of how cells sense and adapt to oxygen availability.”
The 9 million Swedish krona (more than $900,000) prize is shared equally between William Kaelin from the Dana-Farber Cancer Institute in Boston, Peter Ratcliffe from the Francis Crick Institute in London, and Gregg Semenza from Johns Hopkins University in Baltimore.
