The 2024 Nobel Prize in Chemistry recognizes groundbreaking advancements in understanding and manipulating proteins, the molecular powerhouses of life. These discoveries, made by David Baker, Demis Hassabis, and John Jumper, have paved the way for remarkable achievements in computational protein design and protein structure prediction.
Proteins are fundamental to life, serving as enzymes, hormones, antibodies, and the structural components of tissues. They drive the chemical reactions that sustain life and are composed of 20 amino acids, often called life's building blocks. Their unique three-dimensional structures, determined by the sequence of these amino acids, dictate their function. For decades, scientists have sought to predict protein structures based on amino acid sequences—a daunting task until recently.
David Baker, a scientist from the University of Washington in Seattle, made significant strides in 2003 when he successfully designed a novel protein using computational methods. His achievement marked the beginning of an era where researchers could design new proteins with specific functions. Over time, Baker's team has continued to push boundaries, creating proteins with applications in medicine, nanotechnology, and beyond. These innovative proteins can be used as pharmaceuticals, vaccines, sensors, and even as components of nano-materials.
One of the discoveries being recognised this year concerns the construction of spectacular proteins. The other is about fulfilling a 50-year-old dream: predicting protein structures from their amino acid sequences. Both of these discoveries open up vast possibilities.

In another breakthrough, Demis Hassabis and John Jumper, both working at Google DeepMind in London, presented AlphaFold2, an AI model capable of predicting protein structures with astonishing accuracy. Before this breakthrough, predicting protein structures based solely on amino acid sequences was an arduous challenge, dating back to the 1970s. However, with the advent of AlphaFold2 in 2020, scientists can now predict the structure of nearly all known proteins—a staggering 200 million. This achievement has had far-reaching implications, as AlphaFold2 has been adopted by more than two million researchers across 190 countries.
One of the most significant applications of AlphaFold2 lies in its potential to address antibiotic resistance and plastic degradation. By enabling researchers to visualize and understand enzymes' structures, this tool provides crucial insights into designing new drugs and creating environmentally friendly solutions for breaking down plastic waste. These advances underscore the vital role of proteins in addressing some of the world’s most pressing challenges.
The Nobel Committee acknowledged these achievements by awarding David Baker for his pioneering work in computational protein design and jointly recognizing Demis Hassabis and John Jumper for their breakthrough in protein structure prediction using artificial intelligence. These discoveries mark a paradigm shift in the field of chemistry, unlocking possibilities for drug development, environmental sustainability, and technological innovation.
In addition to their research, these laureates have opened the door to future discoveries and innovations. With the ability to predict protein structures and design new ones, scientists can now tackle problems ranging from disease to environmental degradation with unprecedented precision. The integration of AI into protein research, as exemplified by AlphaFold2, represents a transformative leap forward for science and humanity.
This year's Nobel Prize in Chemistry carries the tradition of recognizing work that benefits humankind, continuing from the 2023 award, which celebrated advancements in quantum dots, nanoparticles whose size determines their properties. The prize also comes with a cash award of 11 million Swedish kronor (approximately USD 1 million), provided by a bequest from Alfred Nobel, the Swedish inventor who established the Nobel Prizes.
As protein research continues to evolve, the discoveries of Baker, Hassabis, and Jumper stand as monumental contributions to science. Their work not only deepens our understanding of life’s fundamental processes but also offers solutions to real-world problems, ensuring that their impact will resonate for years to come.
