In his Ted Talk, David Baker, a computational biologist draws our attention to how scientists, inspired by birds, uncovered the principles of aerodynamics. Engineers then used those principles to design custom flying machines.
He says, “In a similar way, we’ve been working for a number of years to uncover the fundamental principles of protein folding and encoding those principles in the computer programme called Rosetta. We made a breakthrough in recent years. We can now design completely new proteins from scratch on the computer. Once we’ve designed the new protein, we encode its amino acid sequence in a synthetic gene. We have to make a synthetic gene because since the protein is completely new, there’s no gene in any organism on earth which currently exists that encodes it.”
Baker’s audacious idea is to pull biology out of the Stone Age through technological revolution in protein design. He refers to the open and conducive collaborative environment nurtured by Bell Labs, to make his case.
The Labs which was home to the invention of the transistor, laser, satellite communication and the foundation of the Internet, has gone on to inspire Baker, who dreams of building the Bell Labs of protein design. Some of Baker’s ideas include, taking proteins from flu strains from around the world and putting them on top of the designed protein particles to make a universal flu vaccine, one shot of which gives a lifetime of protection against the flu.
He also is working towards building advanced delivery vehicles to target existing medications exactly where they need to go in the body – chemotherapy to a tumour or gene therapies to the tissue where gene repair needs to take place. Baker’s team now designing smart therapeutics too that can do calculations within the body and ‘go far beyond current medicines, which are really blunt instruments.’
Baker sums up by telling the audience what his life goal is: Making the world a better place through protein design.

SYNOPSIS: Proteins are remarkable molecular machines: they digest your food, fire your neurons, power your immune system and so much more. What if we could design new ones, with functions never seen before in nature? In this glimpse of the future, David Baker shares how his team at the Institute for Protein Design is creating entirely new proteins from scratch and shows how they could help us tackle five massive challenges facing humanity.
NOTEWORTHY: Baker designs new biomolecules (proteins) from first principles to address 21st-century challenges in health and technology. Baker is fascinated by biological self-organisation. For example: How does the information stored in DNA translate into the intricate world of proteins and cells?
