The Nobel Prize in chemistry has been given to three scientists who developed electron microscopes.
The winners – Jacques Dubochet, Joachim Frank and Richard Henderson – allowed people to see tiny things in incredible detail, allowing for pictures of some of the most fundamental parts of life.
Until the scientists did their work, it was thought it was only possible to use electron microscopes to view dead things, because the powerful beam used destroys living material. But it was this problem that the researchers helped overcome, allowing scientists to fill in gaps in their understanding of how molecules worked.
The Swedish Royal Academy of Sciences said their method, called cryo-electron microscopy, allows researchers to "freeze biomolecules" mid-movement and visualise processes never previously seen.
The development "is decisive for both the basic understanding of life's chemistry and for the development of pharmaceuticals", the academy said.
Scottish-born scientist Henderson used an electron microscope to generate a three-dimensional image of a protein at an atomic resolution, showing the potential of the technology.
His breakthrough was further developed by German-born scientist Frank while Dubochet of Switzerland used rapidly frozen water to preserve the natural shape of the biomolecules.
Chemistry is the third of this year's Nobel Prizes after the winners of the medicine and physics prizes were announced earlier this week.
The prizes are named after Alfred Nobel, the inventor of dynamite, and have been awarded since 1901 for achievements in science, literature and peace, in accordance with his will.
While the chemistry award has sometimes been overshadowed by the towering reputations of physics winners such as Albert Einstein, laureates include ground-breaking scientists such as radioactivity pioneers Ernest Rutherford and Marie Curie, though she also won the physics prize.
The award passed over one of the highest-profile fields of research, the so-called CRISPR-Cas9 gene editing technology that earlier this year allowed U.S. scientists to alter genes in a human embryo to correct a disease-causing mutation.
