Yossi Matias, head of Google Research, is pioneering the use of AI in scientific discovery with two innovative systems: Co-Scientist and ERA (Empirical Research Assistant). Co-Scientist assists researchers by generating and ranking scientific hypotheses, while ERA automates the development of computational models. These tools have already shown promising results, including identifying new drug candidates for acute myeloid leukemia and aiding in understanding antimicrobial resistance. Matias emphasizes the transformative potential of AI in research, likening it to having a 'polymath in your pocket' that can sift through extensive scientific literature. He cites a successful AI study with the NHS that enhanced breast cancer detection rates. Matias believes that as AI technology evolves, it will empower scientists to tackle significant questions earlier in their careers and potentially lead to breakthroughs in treating diseases like cancer. He envisions a future where AI acts as an amplifier of human ingenuity, making advanced research capabilities accessible to a broader range of scientists.
