Deep Dive

This groundbreaking system AlphaFold has revolutionized the understanding of protein structures, a challenge that has perplexed scientists for over half a century. Kohli recounted a compelling story of a biologist who, after a decade of research on a specific protein, utilized AlphaFold to determine its structure in mere minutes. This moment encapsulated the excitement and surprise that many scientists felt upon realizing the capabilities of AlphaFold, which not only predicts protein structures but also elucidates how these proteins interact with other biomolecules, thereby opening new avenues for drug discovery and vaccine development.

The AlphaFold Database, which houses the structures of nearly all known proteins, has become a vital resource for the scientific community. With over 250 million structures available for free, it has been accessed by 1.8 million scientists across 140 countries. Kohli emphasized the significance of this database, noting that it represents a collective leap forward in biological research, allowing scientists to explore protein structures that were previously elusive. The excitement surrounding AlphaFold is palpable, as it empowers researchers to rethink their approaches to biology, akin to how the invention of the telephone transformed communication.

Kohli also discussed the advancements in weather forecasting through DeepMind's GraphCast, which has outperformed traditional models by providing more accurate long-term predictions. He highlighted a specific instance where GraphCast predicted the landfall of Hurricane Lee nine days in advance, while classical models could only manage six days. This capability not only enhances preparedness for natural disasters but also democratizes access to accurate weather predictions, enabling researchers and policymakers to make informed decisions.

The conversation then shifted to the realm of material science, where Kohli described the potential of deep learning to create new materials. He explained the traditional challenges in material discovery, which often relied on serendipitous findings in the lab. With AI, however, researchers can now rationally design materials with specific properties, such as higher energy density for batteries or improved thermal stability. Kohli mentioned the GNNME model, which has expanded the known stable materials from around 50,000 to an astonishing 2.2 million, showcasing the vast possibilities that AI brings to material science.

Kohli's journey into this multidisciplinary field was not without its challenges. He candidly shared his experience with imposter syndrome, particularly when working alongside Nobel Prize winners. Despite his background in computer science, he found himself navigating complex scientific problems, often starting from scratch. This experience underscored the importance of being a generalist in a rapidly evolving field, where the ability to integrate knowledge from various domains is crucial for innovation.

Choosing the right projects is another critical aspect of Kohli's work. He emphasized the need to focus on root node problems—fundamental challenges that, once solved, can have far-reaching implications across multiple disciplines. For instance, understanding protein folding not only aids in drug discovery but also has applications in designing enzymes for plastic decomposition. This strategic approach ensures that the research conducted at DeepMind addresses issues of significant importance and potential impact.

The integration of large language models into scientific research is another frontier that Kohli is exploring. He discussed how these models can process vast amounts of unstructured data from scientific literature, extracting valuable insights that can inform research directions. One of the projects, FunSearch, exemplifies this approach by using a large language model to discover new algorithms for complex problems in computer science. This initiative has already yielded new results, including a breakthrough in the cap set problem, demonstrating the potential of AI to uncover novel solutions.

Kohli also touched on the challenges faced by AI systems in solving complex mathematical problems, such as those presented at the International Math Olympiad. The development of AlphaGeometry, an AI capable of tackling these high-level geometry problems, marks a significant achievement in demonstrating AI's potential in mathematics. Kohli's team generated a vast array of synthetic problems to train the model, enabling it to solve real-world challenges that require deep understanding and lateral thinking.

Looking ahead, Kohli expressed optimism about the future of AI in science. He believes that the next five to ten years will see significant advancements in material design and discovery, particularly in the quest for room-temperature superconductors. The implications of these developments could be transformative, impacting everything from energy storage to medical technologies.
