Trio takes chemistry Nobel for ‘cool’ method to study molecules

– Tea party to celebrate –

But 72-year-old Henderson, from the MRC Laboratory of Molecular Biology in Cambridge, used an electron microscope in 1990 to generate a three-dimensional image of a protein at atomic resolution, a groundbreaking discovery which proved the technology’s potential.

Frank made it widely usable between 1975 and 1986, developing a method to transform the electron microscope’s fuzzy two-dimensional images into sharp, 3-D composites.

Dubochet, today an honorary professor of biophysics at the University of Lausanne, added water.

Now 75, he discovered in the 1980s how to cool water so quickly that it solidifies in liquid form around a biological sample, allowing the molecules to retain their natural shape even in a vacuum.

The electron microscope’s every nut and bolt have been optimised since these discoveries.

The required atomic resolution was reached in 2013, and researchers “can now routinely produce three-dimensional structures of biomolecules,” according to the Nobel committee.

The trio will share the prize money of nine million Swedish kronor (around $1.1 million or 943,100 euros).

“Normally what I’d do if I was in Cambridge, we will have a party around tea-time in the lab but I expect we’ll have it tomorrow instead,” said Henderson.

– ‘Beautiful pictures’ –

The prize announcement was praised by the scientific community and observers around the world.

“By solving more and more structures at the atomic level we can answer biological questions, such as how drugs get into cells, that were simply unanswerable a few years ago,” Jim Smith, science director at the London-based biomedical research charity Wellcome, said in a statement.

Daniel Davis, immunology professor at the University of Manchester, said details of crucial molecules and proteins that make the human immune system function, can now be seen like never before.

“It has been used in visualising the way in which antibodies can work to stop viruses being dangerous, leading to new ideas for medicines –- as just one example,” he said.

John Hardy, neuroscience professor at University College London, said Dubochet, Frank and Henderson’s technique has transformed the field of structural biology.

It has been used, for example, to compile a detailed identikit of an enzyme implicated in Alzheimer’s.

“Knowing this structure opens up the possibility of rational drug design in this area,” Hardy said.

“And as a biologist, I can say that the pictures are beautiful.”
