00:00Inside every plant, animal and human cell are billions of molecular machines working tirelessly.
00:08These machines are composed of proteins, DNA and other molecules, but no single piece function alone.
00:14It's only when we see how they interact and combine in millions of ways that we can truly begin to understand the intricate processes that sustain life.
00:22In a groundbreaking paper published in the prestigious journal Nature,
00:25Google and DeepMind researchers introduced AlphaFold3, a revolutionary AI model that can predict the structure and interactions of all life's molecules with unprecedented accuracy.
00:36For the interactions between proteins and other types of molecules, AlphaFold3 demonstrates at least a 50% improvement compared to existing prediction methods.
00:47For some critical categories of interaction, it has even doubled prediction accuracy.
00:52The researchers hope AlphaFold3 will transform our understanding of the biological world and accelerate drug discovery.
00:59Scientists can now freely access the majority of its capabilities through the newly launched AlphaFold server, an easy-to-use research tool.
01:07To unlock AlphaFold3's potential for drug design, the biotech company Isomorphic Labs is already collaborating with pharmaceutical firms to apply it to real-world drug design challenges,
01:17ultimately aiming to develop groundbreaking new treatments for patients.
01:22This new model builds upon the foundations laid by its predecessor, AlphaFold2, which made a fundamental breakthrough in protein structure prediction back in 2020.
01:32Since then, millions of researchers worldwide have leveraged AlphaFold2 to make important discoveries across fields like malaria vaccines, cancer treatments, and enzyme design.
01:42AlphaFold2 has been cited over 20,000 times already, with its scientific impact recognized through numerous prestigious prizes, most recently the breakthrough prize in life sciences.
01:51AlphaFold3 expands beyond just proteins to encompass a vast spectrum of biomolecules.
01:57This leap could unlock even more transformative research from developing biorenewable materials and resilient crops to accelerating drug design and genomics.
02:07So how exactly does this new model reveal the secrets of life's molecular machinery?
02:12Given an input list of molecules, it generates their joint 3D structure, revealing how they precisely fit together.
02:18AlphaFold3 can model large biomolecules like proteins, DNA, and RNA, as well as smaller molecules known as ligands, a category encompassing many drugs.
02:28Furthermore, it can model the chemical modifications to these molecules that control healthy cell function and contribute to disease when disrupted.
02:36At its core, the new model features an improved version of the Evoformer module, a deep learning architecture that drove AlphaFold2's breakthrough performance.
02:45After processing the molecular inputs, AlphaFold3 assembles its predictions using a diffusion network similar to those used in AI image generators.
02:53This diffusion process starts with a cloud of atoms and converges over many steps to its final, highest accuracy structure.
03:01The researchers state that the model's predictions of molecular interactions surpass the accuracy of all existing computational systems.
03:09As a unified model computing entire molecular complexes holistically, it possesses a unique ability to unify scientific insights across disciplines.
03:18In the realm of drug discovery, it unlocks new capabilities by accurately predicting interactions of drug-like molecules such as ligands and antibodies that bind to proteins, influencing their roles in health and disease.
03:32The model achieves unprecedented accuracy in predicting these drug-relevant interactions, like ligand binding to proteins and antibodies binding their target proteins.
03:42On a key industry benchmark called PoseBusters, AlphaFold3 demonstrates over 50% higher accuracy than traditional modeling methods, without requiring any input of structural data.
03:53This makes it the first AI system to surpass physics-based tools for biomolecular structure prediction.
03:59Predicting antibody protein binding with such fidelity is critical for understanding immune response and designing new antibody therapeutics, an emerging drug class.
04:09At Isomorphic Labs, the researchers are using AlphaFold3 in tandem with complementary in-house AI models to accelerate and enhance the success of drug design pipelines.
04:18They are leveraging it for internal projects as well as partnerships with pharmaceutical companies.
04:23It is helping elucidate new disease targets and identify novel therapeutic approaches for previously intractable ones.
04:29But this model's capabilities extend far beyond drug discovery alone.
04:34Google DeepMind's newly launched AlphaFold server is now the world's most accurate tool for predicting how proteins interact with other molecules throughout cells.
04:43It offers scientists globally free access for non-commercial research purposes.
04:47With just a few clicks, biologists can tap into AlphaFold3's power to model molecular structures spanning proteins, DNA, RNA, ligands, ions, and chemical modifications.
04:58The AlphaFold server empowers researchers to formulate novel hypotheses for experimental testing, accelerating scientific workflows, and sparking innovation.
05:08No longer hamstrung by computational resources or expertise in machine learning, they gain accessible predictive capabilities.
05:15Traditionally, experimental determination of a single protein structure could span an entire PhD thesis and cost hundreds of thousands of dollars.
05:23The previous AlphaFold2 model enabled prediction of hundreds of millions of structures,
05:28a feat that would have required hundreds of millions of researcher years through conventional methods.
05:33The AlphaFold server democratizes this power, allowing scientists to ask bold questions and drive accelerated discovery.
05:40With each new AlphaFold release, the researchers have diligently worked to assess the technology's broad impacts in consultation with the research community and safety experts.
05:50They have adopted a science-driven approach, conducting rigorous evaluations to mitigate risks while maximizing the widespread benefits to biology and human health.
06:00Building upon extensive external consultations for AlphaFold2, over 50 leading domain experts across biosecurity, research, and industry have been engaged to scrutinize AlphaFold3's capabilities and carefully consider potential hazards.
06:15The researchers have also actively participated in community forums and discussions leading up to AlphaFold3's launch.
06:22The AlphaFold server exemplifies their steadfast commitment to sharing AlphaFold's benefits openly, including the free database of 200 million pre-computed protein structures.
06:33They are also expanding the AlphaFold educational curriculum in partnership with EMBL, EBI, and organizations across the Global South.
06:40This will equip more scientists worldwide with the tools to leverage AlphaFold, accelerate adoption, and tackle underfunded areas like neglected diseases and food insecurity.
06:51Responsible development and deployment of powerful AI technologies like AlphaFold remains a core tenet through sustained collaboration with the scientific community and policymakers.
07:01AlphaFold3 brings the biological world into unprecedented high-definition clarity.
07:07It empowers scientists to visualize cellular systems in their full, intricate complexity, from molecules to structures, interactions, and modifications.
